PSG, Mercury Security partner to extend Zero Trust to physical security's far edge

AUSTIN, Texas—Prometheus Security Group Global (PSG) has announced a technology partnership with Mercury Security aimed at bringing Zero Trust principles to the furthest edge of physical security systems, including readers, sensors, door hardware and other field devices. The partnership combines Mercury's access control hardware platform with PSG's technology for embedding cryptographic identity, authentication and verification capabilities directly into field devices. The companies said the effort is designed to help organizations verify the integrity of data before it enters a security system or network. According to the companies, the partnership targets operational technology (OT) Layers 0 and 1, where field devices generate signals and data used by access control and other security systems. The companies said many physical security systems continue to rely on end-of-line resistor technology to monitor device circuits. While effective at detecting faults, those systems generally do not provide device identity, authentication or signal verification capabilities. PSG said its technology enables organizations to cryptographically authenticate field devices and verify signals at their source, reducing the risk of compromised or spoofed inputs entering the system. “Zero Trust begins with knowing that the data entering a system is both authenticated and verified,” said Rick Gross, CEO of Prometheus Security Group Global. “Mercury's leadership in access control, combined with PSG's embedded identity and signal verification at Layers 0 and 1, gives customers a powerful way to strengthen security at the far edge across both analog and digital environments without requiring wholesale replacement of existing infrastructure.” Mercury Security said the partnership aligns with growing customer demand for stronger cybersecurity protections within physical security systems. “Mercury has built its reputation on delivering open, flexible and highly reliable access control solutions,” said Damon Dageenakis, senior director of product management at Mercury Security. “By collaborating with PSG, we are strengthening the integrity of physical security data and supporting the evolving cybersecurity requirements of our customers.” The companies said they will collaborate on technology initiatives, customer engagement efforts and market education programs focused on applying Zero Trust principles throughout physical security environments. The partnership is intended to help organizations strengthen security at the device level while preserving existing investments in access control and other physical security infrastructure.
