OT Cyber Audits

The convergence of operational technology and IT has made cybersecurity more critical than ever, and OT networks are too often the ones left behind.

Why It's Critical

The Gap Most Organizations Miss

Most organizations lock down their IT networks tightly. OT networks often don't get the same attention, and they're frequently managed by facilities staff without dedicated cybersecurity expertise or resources. That's a real problem: much of today's critical infrastructure and facilities equipment wasn't built with security in mind, and some of it hasn't been patched in decades.

DSA's approach, grounded in industry best practices and standards, is built to find those gaps and close them.

Why This Matters

The Case for an OT Cyber Audit

Legacy Systems at Risk

Many OT systems are 30 years old or older and haven't been updated in a decade or more. They weren't designed with cybersecurity as a priority, which makes them easy targets.

Comprehensive Security Measures

An audit baselines your OT environment, identifies vulnerabilities, and puts real protections in place, including networks assumed to be air-gapped or disconnected.

Stronger Cyber Hygiene

As threats evolve, your defenses have to keep pace across the entire enterprise, not just the systems that get the most attention.

DSA's Approach

An Independent, Third-Party Assessment

DSA proposes an independent third-party assessment of your OT systems, including vulnerability management, internal and external penetration testing, and wireless testing across your IP and OT networks. Focus areas include facilities and ICS networks, external and internal networks, and manual verification of assets, ports, and vulnerabilities, not just automated scans.

Penetration Testing Covers

Determining the feasibility of real attack vectors
Identifying higher-risk vulnerabilities created by combined lower-risk issues
Detecting vulnerabilities automated scanning tools tend to miss
Testing your network defenders' ability to detect and respond to attacks
Providing evidence for the remediation that follows

Standards We Follow

NIST 800-53 Rev 4 and SANS best practices
CIS Top 20 security controls
CWE weaknesses and OWASP controls
Ransomware exposure assessment

You'll get a comprehensive final report on tests run, findings, and recommended fixes, plus a risk score modeled on the same 300–850 scale used in credit reporting, so severity is easy to communicate to non-technical stakeholders.
