Layer7 Networking × Tenable

De gouden standaard voor kwetsbaarheidsscanning — van IT tot OT.

Tenable

Tenable is the creator of Nessus — the world's most widely deployed vulnerability scanner — and the company behind the Tenable One exposure management platform. With over 40,000 customers and the largest vulnerability research team in the industry, Tenable provides the depth and breadth of assessment coverage that security programmes depend on.

Tenable's evolution from vulnerability scanning to exposure management reflects the reality of modern attack surfaces: organisations need to understand not just what's vulnerable, but what's actually exploitable given their specific configuration, network topology, and identity relationships. Tenable One delivers this contextual risk analysis across IT, cloud, identity, and OT environments.

Key Products

• Tenable One — Exposure management platform unifying vulnerability data across IT, cloud, identity, and OT. Attack path analysis shows how an attacker could chain vulnerabilities to reach critical assets.
• Tenable Vulnerability Management (formerly Tenable.io) — Cloud-managed vulnerability assessment with risk-based prioritisation. Predictive scoring using VPR (Vulnerability Priority Rating) based on exploit intelligence.
• Tenable Security Center (formerly Tenable.sc) — On-premises vulnerability management for organisations requiring data residency. Full Nessus scanning capability with local data storage and reporting.
• Nessus Professional — Industry-standard vulnerability scanner. 200,000+ plugins covering CVEs, misconfigurations, and compliance checks.
• Tenable OT Security (formerly Tenable.ot) — Purpose-built for operational technology environments. Passive and active scanning of SCADA, ICS, and industrial control systems without disrupting operations.
• Tenable Cloud Security (formerly Ermetic) — CNAPP with CSPM, CIEM, and workload protection. Identity-first cloud security with least-privilege analysis.
• Tenable Identity Exposure (formerly Tenable.ad) — Continuous Active Directory security assessment. Detects misconfigurations, attack paths, and indicators of compromise in AD environments.

Product Capabilities

Why Layer7 Chose Tenable

Tenable's Nessus engine has the deepest plugin library in the industry — over 200,000 checks covering known CVEs, vendor-specific misconfigurations, default credentials, and compliance controls. When a new vulnerability is disclosed, Tenable typically has a detection plugin within 24 hours. This speed matters when zero-days are being actively exploited.

The OT security capability is particularly relevant for Layer7's South African client base. Mining, manufacturing, energy, and water utilities all run industrial control systems that traditional IT vulnerability scanners cannot safely assess. Tenable OT uses passive network monitoring and purpose-built active queries that don't disrupt PLC operations — providing visibility into OT vulnerability posture without operational risk.

For compliance-driven organisations — those pursuing PCI DSS, ISO 27001, or sector-specific regulations — Tenable provides the audit evidence that assessors require. Continuous scanning with historical trending demonstrates that vulnerabilities are being identified, prioritised, and remediated within defined SLAs. This is not optional for regulated industries — it's a compliance requirement that Tenable satisfies directly.

How Layer7 Delivers Tenable

Vulnerability Assessment Programmes

Design and implementation of enterprise vulnerability management programmes using Tenable Vulnerability Management or Security Center. Scanner deployment, scan policy development, asset grouping, and credential management for authenticated scanning.

OT/IT Convergence Security

Tenable OT deployment for industrial environments. Passive monitoring configuration, active query scheduling, asset discovery in OT networks, and vulnerability assessment for SCADA/ICS systems. Bridging the visibility gap between IT security teams and OT operations.

Exposure Management

Tenable One deployment for organisations requiring attack path analysis and contextual risk scoring. Integration of IT vulnerability data, cloud security posture, identity risk, and OT exposure into a unified risk view.

Compliance & Audit Readiness

Configuration of compliance scanning profiles for PCI DSS, ISO 27001, CIS Benchmarks, and South African regulatory requirements. Automated reporting, historical trending, and evidence packages for external audit preparation.

Managed Vulnerability Services

Ongoing vulnerability programme operation: scheduled scanning, results analysis, risk prioritisation, remediation tracking, and executive reporting. Layer7 operates the programme — your team focuses on fixing what matters most.
