Tenable, Tuesday, November 4th, 2025
Discover how the latest NERC CIP standard for Internal Network Security Monitoring (INSM) shifts the focus inside your network, and how Tenable can help deliver the comprehensive visibility required to achieve compliance and enhance security.
Key takeaways:
1. NERC CIP-015 mandates Internal Network Security Monitoring (INSM) to detect threats that bypass perimeter defenses, focusing on east-west traffic within the Bulk Electric System (BES).
2. With compliance deadlines looming in 2028 and 2030, entities must begin planning and implementation now to ensure a smooth path to compliance.
3. Tenable OT Security addresses all core CIP-015 requirements (R1, R2, R3) by providing continuous asset discovery, anomaly detection, data retention, and access control.
