Protocol Harmonization Playbook for Mixed-Vendor OT

Reducing integration drag across legacy and modern controllers and sensors.

Create a canonical OT interface

Mixed-vendor OT stacks thrive on a stable abstraction layer. Build a canonical interface with strict contract tests to prevent bespoke integrations from creeping back. Every exception is future drag.

Close observability gaps

Different protocols expose different signals. Map what each hides and deploy edge collectors to fill the gaps. Blind spots in control systems are operational and safety risks—instrumentation is your insurance policy.

Retire drag with data

Quantify integration drag in hours, defects, and downtime. Use those numbers to prioritize retiring or containing legacy protocols. Decisions backed by drag metrics are easier to fund and defend.

sys3(a)i POV: We approach critical systems work by stress-testing architectures, integrating observability and governance from day one, and designing sovereign or edge footprints where independence and continuity matter most.

What to do next

Identify where this applies in your stack, map dependencies and failure modes, and align observability and governance before committing capital. Need help? Engage sys3(a)i.
