National Energy Grid Operator Cuts Mean-Time-to-Remediate by 68%
A national energy grid operator managing 12,000+ OT assets across 48 substations relied on annual penetration tests and quarterly vulnerability scans. Between assessments, new threat vectors emerged undetected — and manual remediation workflows averaged 45 days from discovery to fix.
The Challenge
A national energy grid operator managing 12,000+ OT assets across 48 substations relied on annual penetration tests and quarterly vulnerability scans. Between assessments, new threat vectors emerged undetected — and manual remediation workflows averaged 45 days from discovery to fix.
The Solution
Piscium's autonomous CTEM platform was deployed across all 48 substations, continuously discovering attack paths through OT/IT convergence points. Offensive AI agents validated exploitability without disrupting operations, while the remediation orchestrator automatically generated and dispatched playbooks to ServiceNow and Palo Alto XSOAR.

Continuous Coverage
Replaced quarterly snapshots with real-time validation
“We went from hoping our quarterly scans caught everything to knowing — in real time — exactly where our exposure is and having automated playbooks ready to close the gaps.”
