The critical role of security technology in a post-covid world

This year marks 20 years since the tragic events of 9/11, which forever changed how we view the role of security technology to protect us against attacks in airports and our public lives. Taking stock of the future of security technology makes it clear that innovation, especially in a post-pandemic world, remains critical in staying one step ahead of emerging threats and addressing changing needs.

I’ve been in the security industry for 30 years now and have been part of technological advances in security detection that have significantly changed how we conduct safety and security operations. I’m amazed to see the continued industry growth that shows no signs of slowing. The simple reason for this is that companies must stay ahead of constantly evolving threats. That means we continually need to develop new technology to thwart more sophisticated weapons that now include 3D printed and ghost guns, plastic and liquid explosives, as well as plastic knives and other concealed weapons.

Unfortunately, we continue to see acts of domestic and international terrorism all too often, and violent crime, as well as gun purchases, are also on the rise. As a result, there is continually expanding demand for cutting-edge security detection technology that does the important job of keeping people safe in our communities and our skies.

Enhanced airport security

Aviation checkpoint security is due for an upgrade to the technologies that were so successfully implemented in the years post 9/11. The gun seizure rate doubled at airports in 2020 despite fewer passengers, and the TSA successfully removed many creatively concealed weapons and other threats. The body scanners that are in airports today are clearly effective but could benefit from enhanced throughput and improved threat detection with higher resolution for fewer false alarms. In addition, the passenger experience can also be improved by not having to divest shoes and other items. As in the last decade and a half, critical airport security needs will pave the way for commercial security applications of the future.

Any location can be a secure location

Technological diligence today also includes securing checkpoints that have recently become vulnerable to attacks, such as hospitals, places of worship, casinos, even grocery stores, hotels, and other hospitality venues. It is evident that safety and security are becoming paramount, and in discussion with operators, they want to have the ability to screen for all potential threats to their business. This includes the latest threats that can be metallic and non-metallic as well as being creatively concealed. This requirement is really going to drive security detection in our day-to-day experience of public life.

Contactless security

Detection is key, but contactless screening is also the new hallmark of security technology needs during the pandemic and after as people begin traveling and going to live events. Contactless screening provides a streamlined, faster experience, moving people through to prevent long lineups without wanding, pat-downs, and bag checks.

Integrated security

Integration with other technologies is important for a layered defense against threats. Open-architecture technology should allow systems to talk to one another, whether that is a walk-through body scanner that integrates with an X-ray baggage screener, shoe screener, or infrared cameras. They all provide connected defense layers of security protection as part of a multi-technology approach.

Innovation then and now has and will continue to guide us in the development of security technology that successfully keeps ahead of the curve of evolving threats. At Liberty Defense, our mission is to protect communities and preserve peace of mind through next generation security detection solutions. The opportunity to work with industry and partners like MIT Lincoln Labs, PNNL, TSA, and the international aviation community is what drives our team to provide disruptive technology.

We will never forget the tragic events of the past, but at Liberty Defense, we are driven to be part of the solution in preventing the next violent event from happening.



Liberty Defense is currently developing leading-edge security detection technology including the HEXWAVE body scanner that can detect metallic and non-metallic concealed threats for use in buildings and indoor/outdoor events for high-throughput screening. Liberty is also developing aviation security technology that includes the millimeter wave-based, High-Definition Advanced Imaging Technology body scanner and shoe screener walk-through technologies that were licensed from a national laboratory and funded by the Department of Homeland Security.
