Get a clear, scored view of your OT cybersecurity maturity - and a practical roadmap to improve it. Automated, IEC 62443-aligned, and built for industrial environments. Results in days, not months.
Traditional OT security audits stall before they start. Scoping calls turn into scoping months. By the time the report lands, the threat landscape has moved on. The HMS OT Cybersecurity Assessment runs in a single two-hour session - you get a maturity score and a prioritised roadmap in days, not quarters, so momentum stays on your side.
OT risk conversations usually break down because everyone's working from a different picture. IT talks policy. OT talks uptime. Leadership wants a number. The assessment gives you all three: a clear maturity score across five NIST domains, mapped to IEC 62443-3-3, in language that works for the plant floor and the boardroom.
A good assessment doesn't just tell you where you stand - it tells you what to do next. Every finding comes with a prioritised action point, ranked by impact, so you leave with a concrete improvement roadmap rather than a list of problems to interpret. Ready to present to leadership the same week you receive it.
Industrial environments face cybersecurity challenges that differ fundamentally from traditional IT. Legacy systems, long equipment lifecycles, and the need for continuous uptime create a uniquely exposed attack surface - one that regulations like NIS2 and IEC 62443 now demand you address.
“How secure is our OT environment today?”
“Where are our biggest risks?”
“Which improvements should we prioritise first?”
The OT Cybersecurity Assessment by HMS Networks gives you clear answers.
The assessment evaluates your environment across 5 categories and 17 subcategories - covering every dimension of IT security from governance to technical controls.
1. Assessment Management: Know what's in your OT network before attackers do.
2. Identify & Access Management: Control who can access critical systems and when.
3. Network Segmentation: Isolate OT from IT and limit lateral movement risk.
4. Patch & Vulnerability Management: Stay ahead of known exploits in legacy-heavy environments.
5. Monitoring & Incident Response: Detect threats and respond before impact reaches production.
6. Backup and Recovery: Ensure you can restore operations when the worst happens.
7. Security Governance & Training: Build the human layer - policies, awareness and accountability.
Designed for organisations where operational technology and IT security intersect - and where a breach could halt production, compromise safety, or trigger regulatory action. These include IT and OT teams in manufacturing, critical infrastructure, and multi-site industrial environments.
Choose a site on where you need the assessment to focus. Get IT and OT responsible together for the interview.
Guided by HMS Networks OT Cybersecurity Specialist, you and your team completes the structured OT cybersecurity questionnaire in approx. 2 hours.
Responses are analysed by HMS Networks OT Cybersecurity specialists and translated into a cybersecurity maturity score per domain.
You receive a detailed report: identified risks, maturity scores, and a prioritised improvement roadmap.
A quantified score across all assessed domains, giving you a clear baseline. More text here to bring it down to 2 lines
Compare security posture across plants and production sites to prioritise investment.

Prioritised recommendations you can act on immediately, not a report that gathers dust.
The assessment maps your findings directly to the frameworks your auditors, regulators, and leadership already speak. No translation required.
IEC 62443: The global standard for industrial cybersecurity. Results map to every relevant security level.
NIST CSF & SP 800: Identify, Protect, Detect, Respond, Recover - findings structured to the NIST five-function
model.
NIS2 Readiness: Understand your obligations under NIS2 and identify gaps before regulators do.
Ready to see where your OT security stands?
With NIS2 in force and industrial attacks rising, "probably fine" isn't a strategy. Book your assessment and turn uncertainty into a scored, prioritised roadmap - mapped to NIST CSF, IEC 62443 and NIS2 - in a single guided session.
