Tenable Exposure Management Platform — Implementation, MS & Support

About the service

Assertiva SA provides professional consulting, implementation, managed, and support services for Tenable, the leader in exposure management. Tenable helps organizations understand and reduce cyber risk by delivering comprehensive vulnerability visibility and actionable intelligence across all assets — from traditional IT endpoints and cloud workloads to operational technology (OT) and industrial control systems (ICS).

The Tenable platform implemented by Assertiva includes Tenable One, the unified Exposure Management Platform that aggregates vulnerability management, cloud security, identity security, OT/IoT security, and AI-powered attack path analysis into a single risk-based view of the entire attack surface; Tenable Vulnerability Management (formerly Tenable.io), the cloud-managed vulnerability management solution powered by Nessus technology for continuous discovery and assessment of IT assets; and Tenable OT Security for asset discovery, vulnerability assessment, threat detection, and configuration control in OT, ICS, and SCADA environments.

Assertiva’s approach goes beyond deployment. We partner with clients from initial asset discovery and exposure baseline through platform configuration, integration with IT and OT environments, risk-based remediation program design, training, and ongoing managed operations.
