Crytica Security Launches RDAi for Deterministic OT Device Tampering Detection

Crytica Security has developed a patented solution called RDAi (Rapid Detection, Alert, and Isolation) that delivers rapid, deterministic threat detection specifically for operational technology (OT) environments. This new system aims to protect the embedded systems and connected devices that are crucial for critical infrastructure, national security, and healthcare sectors, all without causing operational disruptions.

The increasing urgency for such solutions is driven by the rapid evolution of cybersecurity threats, particularly AI-driven attacks. IBM's 2026 Cost of a Data Breach Report indicated a 56% year-over-year increase in AI-driven attacks, while simultaneously, 50% of organizations with Security Operations Centers (SOCs) have already deployed AI agents in production. As both attackers and defenders increasingly operate at machine speed, the confidence in the underlying security signal becomes paramount.

Existing cybersecurity technologies provide essential visibility into networks, communications, assets, vulnerabilities, and behavior. However, Crytica's RDAi complements these external visibility tools by addressing a critical gap: determining whether a device itself remains in a trusted operating state. This is achieved by operating from *inside* each protected device.

The RDAi system detects unauthorized changes to a device's instruction sets and provides deterministic evidence of these modifications. This high-confidence evidence is designed to augment existing SOC, SIEM, and XDR workflows, as well as AI-assisted security operations, without requiring organizations to replace their current cybersecurity investments. The system's 'Probe' is a small agent, less than 100 KB, designed to operate non-disruptively within each device.

"Cybersecurity has become extraordinarily good at observing what is happening around and external to a device, but ultimately, for detection to be truly effective, it must take place inside of each device itself," stated Dr. C. Kerry Nemovicher, CEO of Crytica Security. "If an attacker changes a device’s instruction set and/or any of the other ‘static’ data, such as configuration files, it is imperative that the appropriate alerts be generated. Our approach is to install an ‘Agent’ (called a Probe because it is less than 100 Kb) to reside and operate non-disruptively inside each protected device. Its function is what we call iNSiM….Instruction Set Integrity Monitoring."

This internal detection capability is particularly vital in sectors like critical infrastructure, national security, and healthcare, where compromised devices can have direct impacts on physical operations, essential services, mission readiness, and human safety. Crytica is actively applying its technology across commercial, utility, and federal cybersecurity environments, supported by an expanding ecosystem of security technology providers, OEMs, systems integrators, and channel partners.

"What we’re seeing now is an ecosystem forming around deterministic detection and Crytica is at the vanguard of that effort," commented C. Lloyd Mahaffey, Executive Chairman of Crytica Security. "Customers and technology partners aren’t looking to replace the security investments they already have. They are seeking technologies that can help detect malware and performance anomalies faster. The relationships we’re building across security platforms, OEMs and critical infrastructure reflect that shift and you’ll see more of those collaborations announced in the weeks ahead."

Crytica plans to announce further technology integrations and industry collaborations soon, aiming to extend its deterministic device-level detection capabilities into existing cybersecurity architectures. Unlike current OT and IoT cybersecurity solutions that observe devices externally and infer threats, RDAi promises immediate, internal threat detection with high-fidelity alerts that SOC operators can trust and act upon.
