Perseus Named First Accredited Certification Body for ISASecure ACSSA Program
Perseus Information Security Consulting has achieved a major milestone, securing full A2LA accreditation to become the first authorized certification body (CB) for the ISASecure Automation and Control System Security Assurance (ACSSA) program. This development provides asset owners with a standardized, independent pathway to validate that their Operational Technology (OT) environments conform to the rigorous ISA/IEC 62443 global security standards.
Let’s be honest: for years, "OT security" often felt like the Wild West, where everyone claimed their systems were hardened, but very few could actually prove it to an auditor’s satisfaction. We’ve all seen the "security" white papers that are essentially just marketing fluff. That’s exactly why this accreditation is such a massive deal. By stepping up as the first entity to fully clear the IC49 evaluator certification and achieve ISO/IEC 17065 status for ACSSA, Perseus is effectively moving the goalposts for what true industrial cybersecurity looks like. They aren't just checking boxes; they are bringing the level of rigor we usually reserve for safety-instrumented systems into the realm of general OT control.
For any asset owner struggling to translate the dense requirements of ISA/IEC 62443-3-3 or 62443-2-4 into actual field configurations, having a specialized certification body like Perseus finally operational is a game-changer. It means you can now get a verifiable, third-party assessment that actually carries weight in the industry. Whether you are dealing with legacy SCADA gear or modern IIoT gateways, the ability to demonstrate conformance to these benchmarks is going to become the new table stakes for vendor contracts and insurance compliance. This isn't just another layer of bureaucracy; it’s a necessary maturation of the industrial space. If you’re serious about defending your plant floor against modern threat actors, you need to be looking at the ISASecure designation as the gold standard for your system integration strategy.
