OTNOS is an OT vulnerability intelligence platform for industrial environments. The SaaS service continuously collects security advisories from more than 160 OT vendors and public sources (CISA ICS, CERT feeds), enriches them with exploitation data (KEV, EPSS), and matches them to each customer's asset inventory, so operators of plants and industrial networks know within hours which of their devices are affected and what to do first.

The platform provides risk-based prioritization, digest and instant alerting (email, webhooks, SIEM/SOAR integration), API access, and compliance-oriented reporting aligned with IEC 62443, NIS2, and the EU Cyber Resilience Act. Alongside the platform, OTNOS offers vendor-independent OT security services across the IEC 62443 lifecycle: risk assessments, secure network design, product qualification, and configuration hardening.

OTNOS is operated from Germany with all customer data processed in EU data centers, GDPR-aligned, with security practices documented in this CAIQ self-assessment.
