Your OT risk includes every company with access to your plant
Integrators, equipment makers, maintenance contractors and remote support providers all touch your control systems. SecurityGate.io measures them with the same assessments you use on your own sites, so supplier risk stops living in a separate spreadsheet.
The supplier with remote access is part of your attack surface
Industrial sites run on outside expertise. The integrator who built the control system, the OEM who supports a turbine, the contractor who connects a laptop during a shutdown: each one is a path into OT that your own controls do not cover.
Regulators have noticed. Supplier risk is now written into the main OT mandates.
| Supplier | Assessment | Status |
|---|---|---|
| Controls integrator | IEC 62443 based | Complete |
| Turbine OEM | Remote access set | Gaps found |
| Maintenance contractor | Site access set | Overdue |
| Cloud historian vendor | Custom questionnaire | Complete |

One yardstick for your sites and your suppliers
SecurityGate.io sends suppliers the same kind of assessment you run internally, built on the platform's OT frameworks or on your own questionnaire. Their answers come back into the platform, not into an inbox, and sit alongside your own site results.
Follow-up happens in one place too: questions, clarifications and agreed fixes stay attached to the assessment, so nothing depends on who kept which email.
Assessments that scale to every supplier, not just the biggest ones
When assessments take hours instead of weeks, you can cover the long tail of suppliers that manual programs never reach.
Supplier gaps get owners, deadlines and proof
A supplier gap becomes a remediation item just like an internal one. It can be assigned to the vendor, tracked to a due date and validated before it closes, with the conversation kept on the record.
Business impact views then show which suppliers add risk to which sites, functions and regions, so leadership can see where a single vendor's weakness would matter most.
A supplier program that runs without adding headcount
your IT provider builds the program
Identifies which suppliers touch your OT, chooses the right assessment for each, and handles outreach so vendors respond on the platform rather than by email.
your IT provider keeps it moving
Reviews supplier results with you, follows up on overdue assessments and open gaps, and prepares the supply chain evidence your regulators expect.
Find out which suppliers carry the most risk into your sites
Start with the vendors that have remote or physical access to OT, then extend the same assessment to the rest.
