OT Security Best Practices for Power & Energy Operations
A practical guide to securing industrial systems without disrupting uptime or safety.
What’s Inside the Guide?
Why OT security is now critical
Explains how increased IT/OT connectivity, legacy systems, and third-party access have expanded the attack surface —and why traditional IT security models fail in OT environments.
Core OT security best practices that actually work
Covers practical, field-tested practices across OT visibility, threat monitoring, patching, backups, and third-party access—designed for uptime-critical systems.
How to secure OT without disrupting operations
Focuses on risk-aware patching, passive visibility, non-intrusive monitoring, and recovery planning that respects safety, compliance, and operational constraints.
Real-world OT security outcomes
Includes power and energy case studies showing how visibility, vendor control, and continuous monitoring prevented downtime, reduced risk, and improved resilience.
Modernization is the right move. But doing it without an OT-aligned security strategy creates unnecessary risk.

So How Do You Secure OT Without Breaking It?
Start with OT security best practices
OT Patching: A Risk-Aware Operation, Not a Routine Task
OT patching requires validation, testing, and phased deployment to reduce operational risk and avoid disrupting critical systems.
OT Visibility: See Everything. Miss Nothing
Complete visibility across OT assets and network activity helps detect risks early and eliminate blind spots.
OT Backup Is More Than Storage—It’s Operational Insurance
Tested, secure backups protect critical OT configurations and ensure operations can recover quickly after incidents.
Third-Party Access: Vendors Can Be Your Weakest Link
Strict access controls and continuous monitoring reduce the risks introduced by external vendors and remote access.
