OT Cybersecurity & ISA/IEC 62443
We design and harden control system environments around the ISA/IEC 62443 family of standards and NIST guidance — moving security forward without locking out the people who run the plant. Risk assessments, zone-and-conduit models, and security level targets are translated into practical, sustainable controls.
/ What's included
Scope of work
Practical OT cybersecurity aligned with ISA/IEC 62443 and NIST — segmentation, secure remote access, hardening, patching strategy, and tested backups.
Helps with: 62443 alignment, network segmentation, recovery planning, audit readiness.
- ISA/IEC 62443 zone-and-conduit and risk assessments
- IT/OT segmentation, DMZ design, and firewall policy
- Secure remote access for staff, vendors, and integrators
- PLC and SCADA hardening, account hygiene, and MFA
- Patch and backup strategy with tested recovery
- Policy, procedure, and audit documentation
/ Where this fits
Typical use cases.
- 0162443-aligned segmentation for a multi-plant utility
- 02Replacing shared logins with role-based access and MFA
- 03Establishing tested PLC and SCADA backups
- 04Standing up secure remote access for integrators
