Identity-Based Access for Every Guardian-Discovered Asset — Zero Trust Without Network Change

ConnectCyolo PRO with Nozomi Networks Guardian to turn OT asset visibility intoenforced, identity-based access. Cyolo PRO polls the Guardian asset inventoryand automatically populates its own asset database with discovered devices —name, IP, MAC, vendor, type, and operating system — so administrators buildaccess policies on real, current inventory instead of manual lists.Configurable polling intervals, matching keys, and attribute-override ruleskeep records accurate and deduplicated over time. Every asset Guardiandiscovers can be brought under zero-trust privileged access control, with MFA,supervised sessions, recording, and full audit — without network redesign.

Features
Automated OT Asset Inventory Sync
Cyolo PRO polls Nozomi Networks Guardian on a configurable interval and imports discovered assets directly into its inventory, eliminating manual asset entry and keeping access policy aligned with the live state of the OT network.
Accurate Matching and Deduplication
Cyolo administrators define matching keys and attribute-override rules, so assets already known to Cyolo are enriched rather than duplicated, and the authoritative source is respected field by field.
From Discovery to Enforced Access
Assets surfaced by Guardian become targets for least-privilege connections with MFA, supervision, session recording, and audit — closing the gap between knowing an asset exists and controlling who reaches it.
