OT Cybersecurity Mitigations & Remediations
When a CVE (Common Vulnerabilities and Exposures) is identified, we apply structured mitigation pathways to minimize risk while maintaining operational continuity.
Upgrading Software Version
Updating to the latest vendor-supported software release to address known CVEs and security gaps.
Upgrading Firmware
Applying firmware updates to PLCs, RTUs, and field devices to patch vulnerabilities at the hardware level.
Installing Patches
Deploying vendor-released security patches after compatibility verification in staging environments.
Performing Modifications in SW/HW Configurations
Adjusting system configurations to disable vulnerable features, close unnecessary ports, or restrict access.
Legacy Automation SW/HW Modernization
Planning and executing upgrades for end-of-life automation systems that can no longer receive security updates.
ICS Hardening (Defense-in-Depth)
Employing layered security methods in system design to restrict and control access to individual products and control networks.

Our Services
Explore our OT services
OT Topology Assessment
Per-plant scoped assessment producing documented OT topology — asset inventory, network segmentation evidence, and security-level capability mapping. Scoped per plant, returned within standard SOW timing, delivered to a named owner on your team.
Learn moreOT Topology Authority
Continuous topology authority for your OT environment — not a point-in-time pen test, not an annual vulnerability scan. The operator's source of truth for what is on the network and how it connects.
Learn moreOT Service Owner
Operational extension of the customer's OT team. ITIL-aligned governance, ongoing service ownership across multi-plant fleets. The OT Service Owner cannot be the OT Vendor — structural independence is the operating principle.
Learn moreManaged OT Support Services
A unified operating model for OT security across every plant you run — continuous network monitoring, vendor-coordinated patching, and a 30-minute critical response SLA. Built on Potenza's Defense-in-Depth framework, aligned to NIST SP 800-82r3 and ISA/IEC 62443, and proven to reduce OT-related incidents by 60% in a multi-year cement industry engagement.
Learn moreOT Network Monitoring Services
Continuous visibility across your OT network with active monitoring, industrial IDS, and AI/ML-based anomaly detection for EtherNet/IP, Profinet, and Modbus environments. Integrated into Potenza's Defense-in-Depth framework — proven to reduce OT-related incidents by 60% in a multi-year cement industry engagement.
