Frenos, the industry's only fully simulated AI penetration testing platform, today announced it has been recognized as a Cool Vendor in the Coolest Vendor Innovations in Cyber-Physical Systems (CPS) Security, 2026 report.

Frenos's Simulated OT Penetration Testing Platform tests existing industrial environments for exploitable attack paths and adversary tactics using a digital twin, without ever touching or disrupting the actual production systems. This is important in today's threat environment as attackers increasingly target operational technology directly, and OT operators need a way to test their real exposure without introducing any risk of operational downtime to mission critical services their customers depend on.

"OT operators are under more pressure than ever to prove their environments can withstand an attack, not just pass an audit. After spending a decade on the defender's side of OT security, the honest truth is most OT environments have never been pen tested. Frenos exists because OT asset owners need a technology that helps them move beyond a vulnerability list to understand what is actually exploitable. In our opinion, being named a Cool Vendor tells us we're on the right track. Our job is not done yet, and we will continue to give the people running these plants something they can actually act on," said Brian Proctor, founder and CEO of Frenos.

Frenos has raised $6.4 million to date, most recently through a seed extension led by Momenta and Exposition Ventures, joined by Riptide Ventures. Additionally, Frenos has been awarded $1.1 million from the Department of Energy's (DOE) Office of Cybersecurity, Energy Security, and Emergency Response (CESER). These resources are supporting continued development of the Frenos platform for all critical infrastructure sectors including the federal government and defense.
