OT Security Assessment
Assess cyber risk in operational technology environments without disrupting production systems.
OT environments — industrial control systems, SCADA, PLCs, and manufacturing networks — have unique security requirements driven by availability, safety, and legacy architecture constraints. Mitigence assesses OT risk using passive, non-disruptive techniques that won't impact production.
Engagement Phases
Asset Discovery
3–5 daysPassive network discovery and asset enumeration using OT-safe techniques (Nozomi, Claroty, or equivalent) — no active scanning of production systems.
Architecture Review
3–4 daysReview OT/IT network architecture: Purdue model alignment, DMZ design, remote access controls, and wireless exposure.
Passive Network Analysis
4–6 daysAnalyse network traffic to identify unencrypted protocols, unauthorised communications, and anomalous device behaviour.
Threat Modelling
2–3 daysModel realistic attack scenarios relevant to your sector: ransomware impact on operations, engineering workstation compromise, supply chain intrusion.
Reporting & Remediation Planning
2–3 daysRisk-rated report with operational context — recommendations respect production constraints and safety requirements.
What You Receive
- OT asset inventory and network topology
- Architecture review findings
- Passive traffic analysis report
- Sector-specific threat model
