OT GRC vs a running industrial security program
OT GRC records whether a control exists. A running program assigns an owner, a site, and a close date, then stores the evidence. Resilion is built for the second job.
Two jobs buyers mix up
Plant operators compare us to GRC even when we refuse the label. The table states the jobs. We do not name vendors. Pick the job you need done.
| Lens | OT GRC register | Running program |
|---|---|---|
| Job | Record whether a control exists | Assign the work, close it on each site, keep the proof |
| Input | Framework catalog and attestations | Standards, policies, and the assessments you paid for |
| Output | A register and a status | Site-tiered tasks, owners, and an audit trail as work closes |
| Plant network | Varies by product | Resilion does not sit on the plant network |
| People | Control owners check a box | Named owners receive site-specific work |
What Resilion does in that job
Resilion ingests your standards, policies, and audit findings. It scores maturity against IEC 62443 and NIST CSF, drafts the governance you are missing, routes site-tiered tasks to named owners, and captures evidence as each task closes. Integrations with EDR, IAM, and CMMS are on the roadmap. Do not treat them as shipped.
Hillstrong staffs the work when you want people on the ground. The platform is how that work scales across the fleet. See the Resilion platform. If you are sitting on a binder, read assessment PDF vs a running program. If you already bought a sensor, read OT detection vs a running program.
// FAQ
OT GRC, answered
- Is Resilion an OT GRC tool?
- Resilion runs the program work: it drafts missing governance, routes site-tiered tasks, and stores evidence as each task closes. A GRC register tracks whether a control exists. Those are different jobs.
- Can we keep our GRC tool?
- Yes. Many teams keep a corporate GRC system for enterprise reporting. Resilion is the execution layer for OT program work across plants.
- What standards does this map to?
- IEC 62443, NIST CSF 2.0, and your internal standards. Resilion scores maturity against them and maps controls to each site by criticality.
- Does this replace the assessment firm?
- No. Use the assessment you have. Hillstrong turns those findings into a program you can run. See what to do after an OT security assessment.
