AhnLab CPS PLUS vs Cigent SSD ICS Data Protection: Side-by-Side Comparison (2026)

AhnLab CPS PLUS

Mid-market and enterprise operations teams protecting manufacturing or critical infrastructure will find AhnLab CPS PLUS valuable for its unidirectional data diode capability and portable endpoint scanning, which work in air-gapped or severely restricted OT networks where standard agents fail. The platform covers 10 of 23 NIST CSF 2.0 functions with particular strength in asset identification, continuous monitoring, and incident analysis across IT and OT together. Skip this if your priority is recovery and resilience post-breach; AhnLab emphasizes prevention and detection over response coordination, and the Asia-Pacific vendor presence means longer support latencies for North American teams.

Cigent SSD ICS Data Protection

Mid-market and enterprise OT teams protecting critical infrastructure from data exfiltration need Cigent SSD ICS Data Protection because it enforces encryption and erasure at the firmware level, making data unrecoverable even if adversaries gain physical access to drives. The dual-layer encryption aligns with NSA Commercial Solutions for Classified requirements, and the patented block-by-block verified erasure actually proves deletion rather than assuming it. Skip this if your threat model is primarily logical access and insider threat; Cigent's value is defending against nation-state adversaries and sophisticated theft of ICS artifacts, not preventing lateral movement across your network.
