Targeted hardening of PLCs, HMIs, RTUs and gateways, from factory defaults to a hardening baseline.
OT environments run nonstop, 24/7. Yet pre-installed, unnecessary software, open ports and unused user accounts create new attack vectors. We eliminate this “overlapping attack surface” by auditing, documenting, and safely removing every extraneous component.
Continuous uptime is non-negotiable in OT. Any excess functionality or accounts can be exploited. Hardening reduces risk by removing software, ports and permissions that threat actors could leverage.
More stable systems: Fewer software/service failures, improved operational reliability.
Reduced attack surface: Fewer entry points and exploit paths for attackers.
Simplified auditing: Less components & accounts means faster, clearer compliance checks.
Automated & manual asset discovery; baseline firmware & configuration.
Identify unused services, open ports, scripts, user accounts & permissions.
Schedule controls prioritized by risk and business impact.
Remove unneeded components, tighten configurations, restrict access.
Functional testing, regression checks, security monitoring setup.
Ongoing reviews, patch management & change-control guidance.
This service is particularly valuable in the sectors below, due to their specific regulations, asset base and threat models.
