One of the most rewarding things about our work at Evolv is that we get to help people do the things they love with a greater sense of safety, security, comfort, and convenience. It’s not just something we sense; it’s something we see and experience. It happens in every customer engagement, yet it particularly hit home for Jeff and me working with our first MLB team.
Jeff and I are big baseball fans. We know that one-of-a-kind feeling of going to the ballpark, seeing that lush green diamond and spending the day cheering or commiserating with family, friends and like-minded strangers who share a common bond. Once you’ve had that experience, it becomes a part of your very essence.
In 2020, fans were deprived of that experience because of COVID-19. It was a tough year for professional baseball, as it was for so many of the simple joys in life that we normally take for granted. The teams played the games, but the fans stayed home.
As we head into the 2021 season, one of the top priorities for Major League Baseball is to bring fans back to the ballpark. Each team must think about delivering a safe experience for everyone who enters. We are proud to be part of our first Major League Baseball security solution to deliver a safe experience for their fans, and anyone else passing through.
Earning Our Place in the Line Up
We were put to the test, and we passed. We have become embedded with the expert security and operations teams. We always say to our customers: “We are an expert in our technology, you are an expert in your space”. Nothing could be closer to the truth.
At Evolv, The Mission is Personal
For Jeff and me, and for all of us at Evolv, there is a personal connection to the work we do. We know we are creating a safer and better environment for people to do the things they enjoy or go back to work with less fear and trepidation following the trauma of COVID.
Jeff says the camaraderie in baseball is akin to what he feels working at Evolv, the spirit of all being in it together and believing we can accomplish great things. As he told me the other day: “I’ve never experienced such dedication and commitment in any job I’ve ever had. I feel like I’ve known the people at Evolv forever.”
For many people, baseball is an important part of forging connections. Fathers and sons, grandfathers and granddaughters, friends and family. And as we talked, we both felt a wave of pride knowing that we, in our own small way, are helping reopen ballparks for our country’s favorite pastime and enabling those connections to continue once again at one of the most celebrated and iconic venues in America. What more could you ask for?
The continued acceleration of the digital transformation has unleashed seemingly limitless possibilities for technological applications, from the widespread global standpoint all the way down to the personal level. The emergence of artificial intelligence (AI) presents incredible opportunities in many arenas, including the practical application of physical security.
Anil Chitkara, Evolv Technology Co-founder and host of Digital Threshold Live, was joined by Mahesh Saptharishi during episode No. 4 to discuss the technological possibilities at the intersection of sensors and AI. Saptharishi is the CTO of Motorola Solutions and leads innovation of mission-critical communications, as well as video and command center software.
Saptharishi provided a detailed and thorough perspective on the synergies of machine learning, AI, big data and analytics and how each plays a necessary part in the digital threshold and the creation of state-of-the-art physical security systems.
“Machine learning are the core algorithmic capabilities that power AI,” Saptharishi said. With regards to physical security, “when cameras, or when systems, see things, detect objects or respond to what the objects are doing in the scene, that is artificial intelligence, but that ability to detect and the ability for that system to adapt to the environment is powered by machine learning algorithms.”
Episode 4 Highlights and Provides Insights on the Security Threshold
Saptharishi explained that AI has come a long way in the past 10 years as computing power and speed have taken major strides – in large part due to the evolution of gaming GPUs.
“I think storage becoming cheaper, network bandwidth becoming cheaper, the ability to collect data becoming more practical – that acted as a fuel that powered all these algorithms to develop further and actually reach their performance potential and become practical through the processor technology that has come out,“ Saptharishi said.
This has been instrumental in AI development. One such real world application is AI understanding audio and speech patterns, as well as analyzing video. Utilizing improved GPU technology, these computations can now be done in real time. What once was done with multiple computers can now be done from your phone.
Chitkara asked about the human impacts of AI and whether this technology is replacing people or helping them.
To a degree, AI can replace or augment existing jobs done by humans.
“But, that said, humans are not static entities in terms of how we apply our intelligence,” Saptharishi said. When AI replaces certain tasks, people can focus on other areas where AI does not apply presently or perhaps cannot perform in the same way a human would.
For example, AI can assist law enforcement by helping search for people on video or by calling the attention of the officer to a particular situation that would require human judgement on whether or not intervention is applicable.
Saptharishi also explained the process of developing AI for particular applications. It starts by identifying the human factor opportunities. By shadowing individuals as they progress through their normal tasks, the development team can determine tasks that can be automated or assisted through technology.
This can greatly increase the productivity of the individual. With the automation of sensory actions, people can do things earlier, faster and also allow for more response time to particular situations, as technology has assisted in collecting information in an expedited manner.
In terms of security and technology, Saptharishi noted some key trends that have emerged. One trend is the combination of sensing modalities to create more powerful solutions. Other trends are the increased utilization of cloud connectivity and the integration of public safety, private security and enterprise security.
Chitkara and Saptharishi also discussed the security threshold and the factors that make AI successful for this application.
“Along with this notion that you need a high throughput solution, the threshold cannot become a bottleneck,” Saptharishi said.
The technology threshold needs to be as seamless as possible and not become an overwhelming burden to the flow of people. Secondly, the threshold needs to identify a person along with the right context. Is this person permitted to enter? Along with that identity permission, is this person bringing along something that is not permitted, such as a weapon or an illness?
“The days of somebody sitting in front of a security operations center, watching a video wall, hoping that they can detect something that is potentially suspicious or requires attention – I think those days are starting to reduce,” Saptharishi said.

The New Normal
Throughout this global pandemic period I’ve had many conversations with leaders responsible for people screening at live sports and entertainment venues, workplaces, schools, houses of worship, and outdoor theme parks across America. We’ve all felt a pandemic anxiety. Along with our heroic first responders, few feel it more acutely than these men and women responsible for helping people safely gather in a time when the act of gathering itself has become a mortal threat. Their entire world was shut down and is now in the process of reformatting and rebooting.
Most of the security leaders I am talking with are struggling with how to reopen safely, attract visitors, and stay open indefinitely. One thing I know for sure: there will be no going back to the old screening procedures. Why? Because three waves of change are combining to crest and crash down on the thresholds of their venues at the same time. The future of people screening will be quite different indeed, but it will be much, much better—at least for those who learn to adapt.
So, what are these three waves of change? They are the Normalization of Pandemics, Armed Anxiety, and the Digital Transformation of Physical Security. Let’s look at each in detail.
Wave 1: Normalization of Pandemics
Pandemic viruses turn unwitting visitors into weapons. COVID-19 has weaponized people in a way never seen before. Everyone now knows that packed crowds and human contact multiply the danger. Visitors and employees are looking at every venue and workplace with new eyes and formulating an internal risk score based on what they see. They are highly sensitized and are looking for evidence that the operators “get it” and have taken action. They don’t always know what they should expect, but they absolutely will expect security screening to be visibly different. COVID-19 has changed the risk profile of gatherings forever. A pandemic-aware security posture is the new normal.
Traditional high-touch entry screening is obsolete. Helping visitors feel safe in the new environment while delivering a financially sustainable entry throughput is just not possible with old metal detectors, manual bag inspections, and the resulting crowds. Along with new regulations and mandated protocols that venues must abide by, visitors and employees now also want to see a very orderly, safe, and socially-distanced people flow. A touchless visitor experience is part of the new normal.
A pandemic-aware security posture is not some passing fad. There have been six serious pandemics in just the last two decades: SARS, MERS, avian flu, swine flu, Ebola, and now COVID-19. Will there be more? Absolutely. Every physical security team must now develop the ability to adapt to future pandemics that are certainly on the way. Ongoing pandemic readiness is part of the new normal.
Evolv Technology customers, such as Six Flags and Hersheypark, have adapted to the pandemic by rolling out a new comprehensive health and safety plan for reopening their amusement parks. In the case of Six Flags, they’ve added thermal imaging for identifying guests with elevated body temperature and Evolv’s touchless security screening as part of their social-distancing procedures. We believe this is the beginning of a new trend of multi-threat screening that is changing venues and guest experiences forever.
Wave 2: Armed Anxiety
Research shows that there are as many as 393 million privately owned guns in circulation in the United States. The recent pandemic has spurred a new surge in gun purchases. More guns were sold in the first eight months of 2020 than were sold in all of last year. While most crime has significantly declined during the pandemic, shootings and killings remain at pre-pandemic levels.
Soon after pandemic lockdown orders started to lift, there was a venue-targeted active shooting incident in Arizona, and other active shooter incidents in Kansas and Texas. In 2020 the U.S. is on track to have an all-time record year for mass shootings, having reached the 2019 total of 417 on September 2, with four months still left to go.
The fact that shooting incidents persist amid the pandemic is unsurprising when we consider the historic levels of depression and anxiety that people are experiencing right now. The CDC reports that 40% of U.S. adults reported struggling with mental health or substance abuse during the pandemic—with the prevalence of anxiety being three times higher and depression four times higher than the same period last year.
The combination of an unprecedented number of weapons and unprecedented levels of anxiety and depression creates an unprecedented danger. We are living in an era of armed anxiety. Even though people are not gathering at scale today, that will change someday soon. Any gathering or workplace could be the next target. Any employee or visitor could suddenly erupt into the next violent threat. It could happen anywhere at any time.
Wave 3: The Digital Transformation of Physical Security
Outside the physical security world, businesses in every industry are unlocking efficiency and value by digitizing old manual and analog processes. They are re-imagining their organizations and operations in a future defined by software, data, sensors, mobility, networks, machine learning, automation, and analytics. It isn’t change for the sake of change; it’s change to allow the business to perform better in the modern world and be ready to respond more quickly to change in the future.
Anheuser-Busch InBev is using machine learning to help bars create more accurate orders, resulting in better customer satisfaction. Walmart is using shelf-scanning robots to optimize inventory performance. Black & Decker is using networked sensors to track the movement of materials in factories to increase labor efficiency and quality.
Is digital transformation worth the effort? Yes, with the greatest rewards going to those who start early and do it right. Across all industries, digital leaders clearly outperform the laggards in their industry in both growth and profitability according to recent Bain & Company research:
After comparing financial results for five categories of companies based on their degree of digital maturity, Bain found that revenues for the digital leaders grew 14 percent over the past three years, more than doubling the performance of the digital laggards in their industries. Profitability followed a similar pattern—83 percent of the leaders increased margins over that period while less than half of the industry laggards did so.
Unfortunately, physical security stands out as a laggard in digital transformation—especially when compared to the modern cybersecurity best practices that I am used to. Consider the findings of Accenture and Microsoft in their recent survey of physical security leaders:
“We found that although security leaders see the opportunity to enhance risk management with digital capabilities, the industry is at various levels of maturity, and at worst is a decade behind. Respondents identified “reactive threat management” and “intuition-led decision-making based on subjectivity” as the two leading challenges facing physical security operations today. These challenges—operating reactively and improving decision-making—make it difficult to be proactive. This puts your people, brand and reputation at risk.”
It’s not surprising that physical security managers are worried about “reactive threat management” and “intuition-led decisions” when their security screening technology hasn’t fundamentally changed since the 1920s and is completely devoid of digital data. Old analog metal detectors, hand wands, and manual bag inspections are artifacts of a pre-digital age. Weapons screening sometimes feels like the land that time forgot.
Today’s lack of modern technology in physical security operations has created an undue reliance on security staff. The security officers are burdened with an ever-growing list of tasks: watch out for bad behavior, answer guest’s questions, handle minor incidents, and clean up the physical space, in addition to the core screening role of manually checking everybody entering for prohibited items. There are simply too many things for any one security guard to manage.
Things could not be more different in the cybersecurity part of the business. Because cybersecurity was born inherently digital, cybersecurity professionals are immersed in oceans of digital data and refined pattern recognition based on cutting edge artificial intelligence. They have deep and meaningful analytics and real-time threat intelligence that help them adapt to new threats, in real time, and continuously tighten their perimeter.
The Rise of the Digital Threshold
How long will it be until we close the gap between the digital haves in cyber and the digital have-nots in physical security? It’s already happening. A new vision and technology architecture are emerging. We call this vision the Digital Threshold. The Digital Threshold vision applies the proven patterns of digital transformation and cybersecurity to everything that happens in the space people cross as they enter and exit modern venues and facilities.
Within the Digital Threshold vision, venues and facilities can intelligently use data to create a frictionless experience for guests and employees. The result is an entry process that enhances the overall experience instead of diminishing it as it so often does today.
Making weapons screening faster and more precise is part of the Digital Threshold vision, but it’s just the beginning. What if the entry experience could also seamlessly integrate digital health screening and health credential processing into the screening process? What if electronic ticketing, VIP identification, and BOLO alerts could also be part of the same seamless flow? And what if the Digital Threshold generated useful analytics that enable data-driven decisions about system adjustments and people flows? All of this is part of the Digital Threshold vision that not only addresses the current environment, but also creates the ability to adapt and flex to handle future needs as necessary.
The Digital Threshold as a Technology Architecture
The Digital Threshold is more than just a vision for frictionless entry experiences—it’s a digital technology architecture of components that work together to realize the vision. These components include Sensors, Analytics, and Actions, all on top of the AI Platform.
In the Digital Threshold vision, sensors work together to spot multiple threats and to supply useful insights about visitors. Each sensor fills in a different part of the picture. Data from magnetic field sensors make it possible to see the difference between a gun and a smartphone. Thermal imaging cameras provide the raw data that makes it possible to spot people with elevated body temperature—a sign of potential infection. Visible light cameras could gather the imagery needed to count visitors, estimate visitor demographics, and identify visitors as employees, VIP season pass holders, or known threats. Microphones, biometric and credential readers, and other types of sensors could supply added insights about who and what is coming through the Digital Threshold.
As threats evolve and new sensors emerge, the Digital Threshold sensor array can expand as needed. Rather than sending visitors through an obstacle course of standalone technologies, the Digital Threshold allows venues to touchlessly screen for multiple threats in a single concept of operation (CONOP).
AI Software Platform
Digital Threshold sensors produce a flood of raw digital data that must be stored, organized, and turned into meaningful information. That’s where the AI software platform comes in. It’s the brains of the Digital Threshold vision.
AI uses machine learning to spot complex patterns in data. More data and more kinds of data make machine learning models more precise over time. Having multiple digital sensors makes it possible to bring everything together in a way that increases situational awareness.
The core value of the Digital Threshold vision is embodied in software. The hardware is almost incidental and will someday come in many different forms. Instead of installing new hardware to improve accuracy, the machine learning models could be upgraded just like the software on smartphones. This completely changes the game of system upgrades. As the Digital Threshold gets smarter over time, rolling out new capabilities becomes a matter of clicks, not forklifts.
At Evolv, we call our AI software platform the Evolv Cortex AI™. From the beginning we designed Cortex AI to be upgradable and extensible across a wide variety of threats. It’s the brain of all our products and an early expression of the Digital Threshold vision.
When the AI software platform identifies a problem, imagine if the Digital Threshold action flow engine could spring into action to orchestrate the appropriate response. It’s about much more than beeps and alarms. Imagine if visitors could see a temporary “Slow Down” message when sensors detect crowding that violates social distancing requirements. If a potential weapon is spotted, the visitor might be visually directed to a weapon screening resolution station on the left, while a person with elevated body temperature could be directed to a health screening station on the right. Season ticket holders might be greeted with a “Welcome Back!” display.
Whatever the situation, the Digital Threshold could guide visitors and guard staff with a suitable programmed response. The key word is programmed. Because it would be a software workflow engine, actions could be changed and customized over time without a hardware upgrade. It’s software-defined physical security that could prove to be just as revolutionary as software-defined networking.
Because the Digital Threshold feeds on digital data, it could become possible to generate an ever-growing number of useful analytics to help plan and execute a frictionless experience. For example, based on the type of event, day of the week, forecast weather, and current tour of a specific performer, a Digital Threshold-equipped venue manager could potentially answer questions like the following:
- What time did the arrival rate peak before last week’s event?
- What is the mix of families and demographics of individuals coming through different entrances?
- Is entrance throughput consistent with our social distancing guidelines?
- Which doors seem to attract the most VIPs?
- What are the demographic characteristics of our visitors by entrance?
- What is the alarm rate at each entrance?
- What are the top threats detected at each entrance?
Once the data is in an analytics platform, there is almost no end to the questions we might answer. Remember the Accenture and Microsoft research finding that physical security managers were worried about “intuition-led decisions?” Having powerful analytics could be a huge step down the path to data-driven decision-making. These analytic insights not only keep people safely moving based on their risk profile but also allow for venues to monetize the visitor experience more effectively.
Toward Agile Readiness
These four components of the Digital Threshold come together to transform the screening process to both block today’s known threats and quickly adapt to future threats as they emerge. I call this the state of “Agile Readiness.” Modern venues with agile readiness can quickly flex and surge into whatever comes next.
While it is impossible to specifically predict every new threat, digital technology makes it possible to reduce the window of exposure and minimize disruption. It’s about generating, harnessing, and trusting data to make the most important decisions about safety instantaneously. It’s about maintaining a security posture that engenders trust and confidence among employees and visitors. It’s security that is obvious but low-profile, strong but not invasive, fast but not cumbersome. That’s what the Digital Threshold vision could deliver, creating Agile Readiness.
Software Eats the World of Physical Security
Web pioneer Marc Andreessen has famously claimed that “software is eating the world” and I completely agree with him. The most interesting thing about cars these days is the software that makes them more efficient and safer. The most interesting thing about a watch these days is the software that makes it a fitness and health tracker and an extension of my phone rather than just a timepiece. The hardware of modern technology is still important, but more often only as a vessel for the innovative software it contains.
At Evolv, we are bringing the “software eats the world” phenomenon to security screening, and it’s already creating incredible value for our customers. Our early implementation of the Digital Threshold vision is successfully devouring the old security screening technologies, and it shows no signs of slowing down. It’s also empowering security teams to do an even better job of keeping people safe while optimizing financial and staff resources.
The software platform supplies the brain and connective tissue to integrate capabilities of new emerging technologies that transform the new visitor or fan experience. It becomes the security platform to seamlessly integrate biometrics, video analytics, crowd intelligence, health posture data, electronic ticketing, and on-demand liability wavers to allow for a frictionless visitor, employee, and fan experience in a post COVID-19 world.
We have made substantial progress in realizing the Digital Threshold vision in the Evolv product line. Customers are telling us we have it right, but in many ways, we are just getting started. There’s a lot of room left to apply artificial intelligence to physical security, including new types of sensors to consider and analytics to create. It’s an extremely exciting time.
Addressing the realities of pandemics and armed anxiety while also developing the potential of digital transformation will require a new approach. We must reimagine these challenges and opportunities in a whole new light, unbound by legacy technologies or preconceived, outdated ideas. Armies of people using old ways of working simply cannot keep the public safe. The old solutions don’t scale wide enough or deep enough to address these threats everywhere they can appear. Much like we’ve seen in other industries, technology can fundamentally bend the curve back in our favor and return peace of mind. And peace of mind is what we all want and deserve, now more than ever.
One Chance to Get it Right
I believe that the realization of the Digital Threshold vision is inevitable, and the time to get started is now. I also believe that the transition will create winners and losers. Facilities that embrace and adapt to the digital future will earn lasting trust and long-term viability and loyalty. Facilities that are slow to adapt may never recover from the resulting loss of business and trust.

All around the world, attacks on soft-targets — churches, nightclubs, shopping districts, train stations, sports stadiums — have become an all-too-common occurrence. We at Evolv Technology aggregate these outrages in our daily newsletter, The Scan, and too many of them share the same maddening story line: a troubled person, often known to authorities as a possible terror threat, walks into a venue unimpeded and causes mass casualties. Government officials bemoan the tragedy, sometimes warning citizens to get used to this “new normal.” Terror organizations are emboldened. Shortly before ISIS spokesman Abu Mohammad al-Adnani was killed by a U.S. drone last summer, he urged lone wolves around the world to action. “The smallest act you do in their lands is more beloved to us than the biggest act done here,” he wrote in ISIS’ online magazine.
We started Evolv three years ago to give security professionals a fighting chance against these anytime, anywhere attacks. Last month, we announced our first hardware product — the first ever body scanning system designed from the ground up for use at soft-target locations. It’s called the Evolv Edge™, and it differs from traditional products in four main ways.
It’s fast. Evolv Edge can check up to 600 people per hour for concealed firearms, non-metallic explosives, suicide vests and other threats, without requiring anyone to empty pockets or take off shoes. So long as people walk at normal speed and go through one at a time, they might not even notice they are being scanned.
It’s connected. The Evolv Edge can be configured to provide real-time alerts when a terror suspect or criminal approaches the system. A camera in the column of the unit captures footage of approaching people. By the time they arrive, the imagery has been compared to official watch lists for possible matches. Customers can also opt to have the matches sent off to a human expert for real time review, to increase the likelihood of a positive ID before interdicting the suspect. The process typically only takes a few seconds more. (We don’t keep any of the imagery or other information we collect on individuals.)
It’s easy to use. No one is looking for another security system that requires extensive training, and is only as good as the operators’ ability to stay vigilant hour after hour. We designed a simple software interface, in which potential problems show up as a red alert on a photograph of the visitor.
Under the covers, the software offers simple but powerful controls that enable users to adjust the system— say, to automatically turn up the scan sensitivity for unrecognized visitors or to turn it down when a badged executive walks through. But our goal was to create a system that any temp security guard can use with minimal training.
Evolv Edge is portable. The system is comprised of two 5’6” towers that weigh a combined 250 lbs. It comes on wheels, so can be easily rolled into place and be up and running in less than 30 minutes. Use it to screen employees and visitors at the main entrance of your facility, or move it to add a random, unobtrusive layer of security in response to heightened threat levels..
Many of us at Evolv Technology are veterans of the security screening business. We built Reveal Imaging Technologies, a leader in checked baggage explosives detection which is now part of Leidos. But to create Edge, we had to throw out much of what we had learned in the past. Rather than bake all of our technical capability into the hardware, we took a much more software-centric approach. That way, Evolv Edge could be reconfigured for a broad set of environments and applications. Rather than obsess over spotting the smallest pen-knife, we recalibrate our priority to focus on the most dangerous threats, but in far less time and with far fewer false positives. And for the first time, we had to worry about aesthetics. After all, Evolv Edge units won’t be tucked away at some nondescript checkpoint, but will reside in office atriums, stadium entrances and in front of restaurants and night clubs. They’ll have to look good.
Judging from the early response to the system, we’ve hit a nerve. We’ve spoken with more than 300 entities, ranging from leading transportation authorities to rock and roll band managers looking for a system they could take on the road to concerts. Some of these parties are anticipating upcoming regulation. For example, governments around the world are considering mandatory curbside screening at airports, to avoid the types of attacks that occurred in terminals in Brussels and Istanbul earlier this year. Other companies are determined to find cost-effective means to prevent the most heinous, mass casualty attacks, both to protect life and limb and because they believe they will increasingly be judged by their ability to keep employees, customers and other visitors safe.
While we recognize we are just at the start of a long journey, we’re confident the Evolv Edge™ system is an important first step. We deployed it at the entrance to one of the sections of UK Security Expo last month, and it performed admirably during the two-day test drive. We think of it as a basic building block — a layer that almost any company can use as part of a security system to meet its particular needs.
If you agree that there are too many media headlines proclaiming the tightening of security AFTER an attack, then we should connect.
