OT SECURITY

Operational technology runs the physical world — the pumps, valves, turbines, and production lines that keep manufacturing, energy, and utilities moving. When those systems fail, the cost is not a data breach; it is downtime, damaged equipment, and risk to people. Assessing them takes a different discipline from testing a web application: you cannot fuzz a PLC in production the way you would a login form. Our certified team assesses OT and industrial environments, and every engagement starts from a single rule — production safety and availability come first, always. We help asset owners find and fix weaknesses in their SCADA and ICS estates before an attacker or an accident does.

OT Security Assessment

OT systems such as SCADA and ICS are the backbone of manufacturing, energy, and utilities industries. These systems control and monitor physical processes, making them prime targets for cyberattacks that could disrupt operations, cause financial loss, and endanger public safety.

Our comprehensive assessment is specifically designed to protect SCADA and ICS environments. Our team of highly qualified cybersecurity professionals identifies and addresses vulnerabilities across your entire OT infrastructure — covering firewalls, DMZ, sensors, instrumentation networks, and control systems.

Approach

• Both active and passive techniques used while systems are in production
• Minimal impact on operations and maintained availability
• Evaluates security against industry standards and frameworks:
  • NIST CSF
  • IEC 62443
  • NERC CIP

How we work

Every OT engagement follows the same five-step process, built around the reality that these systems cannot simply be taken offline for a test.

1. Scoping — We map the environment with you: the Purdue levels in play, which zones and conduits are in scope, the specific PLCs, RTUs, HMIs, and historians involved, and where the IT/OT boundary sits. The proposal states exactly what will be assessed and how deep — no open-ended activity near safety-critical systems.
2. Rules of engagement — Before any traffic touches the network, we agree on maintenance windows, off-limits assets, emergency contacts, and a clear escalation path. Anything that could affect a live process is scheduled with your operations and engineering teams first, and nothing intrusive happens without their sign-off.
3. Execution (passive first) — We begin with passive techniques: network traffic capture, asset discovery, and configuration review, so we build an accurate picture without sending a single packet a controller did not expect. Active testing is introduced only where it is safe, and always during agreed windows with operations staff on hand. Production safety is never traded for coverage.
4. Reporting — You receive a report written for two audiences at once: an executive summary that frames risk in terms of operational impact and safety, and technical findings that your control-system engineers and integrators can act on, each mapped to the relevant framework.
5. Retest & debrief — After your team and vendors remediate, we verify the fixes — passively where possible — and update each finding's status. The engagement closes with a debrief that includes both your security and operations stakeholders, not a PDF dropped in your inbox.

What you get

Every assessment is documented for both the boardroom and the plant floor:

• Executive summary — a risk picture framed in operational terms: what could disrupt production, damage equipment, or endanger safety, and how likely it is.
• Findings with severity ratings — each issue scored with CVSS and, crucially, weighted by its real operational and safety impact, so remediation can be prioritised where it matters.
• Reproduction & evidence — clear documentation of each finding with supporting evidence, gathered in a way that respects the sensitivity of a live control environment.
• Remediation guidance — practical, OT-aware fixes that account for legacy equipment, vendor constraints, and the fact that patching is rarely as simple as it is in IT — not a copy-paste of scanner boilerplate.
• Retest verification — findings are re-checked after remediation and the report is updated to reflect closed items.

We have delivered zero blank reports in the company's history — every engagement so far has surfaced real, validated findings.

Team credentials

Assessments are performed by our in-house team holding industry certifications including OSCP, OSCE, CREST CRT, CREST CPSA, and GIAC GREM — credentials earned through rigorous, hands-on examination. The same team presents its research at international venues and has served 180+ clients across finance, enterprise, and critical sectors. That practitioner background is what lets us work safely inside sensitive industrial environments rather than treating them like ordinary IT networks. See the full list of certifications the team holds.

Standards & compliance

Our OT assessments evaluate your environment against the frameworks that matter for industrial and critical infrastructure: NIST CSF, IEC 62443, and NERC CIP. Findings are mapped back to these standards so you can show auditors and regulators where you stand and demonstrate measurable progress between engagements. If your assessment needs to produce evidence in a specific format for an internal audit or a sector requirement, tell us during scoping — aligning the report costs nothing at that stage.

For IT-side systems, cloud environments, and applications that sit alongside your OT estate, pair this with a conventional penetration test so the whole attack surface — from the corporate network down to the plant floor — is covered.
