Tenable is a leader in vulnerability management. Senserva focuses on Microsoft 365 configuration posture and adds an independent patch double-check.
Tenable (Nessus, Tenable One) is a recognized leader in vulnerability and exposure management across infrastructure. Its strength is finding software vulnerabilities broadly. Senserva is complementary and Microsoft-focused: it audits Microsoft 365 configuration posture and verifies patch coverage across Microsoft's own APIs, the SaaS control plane Tenable is not built for.
Demo and Game Mode run free, no registration, no access to your tenant. Windows and Mac.

Senserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Tenable.
| What Tenable does well | Where teams want more |
|---|---|
| Industry-leading vulnerability scanning (Nessus) and exposure management. | Focused on infrastructure vulnerabilities, not Microsoft 365 SaaS configuration posture. |
| Broad asset coverage across on-prem and cloud infrastructure. | Entra ID, Intune, Exchange, SharePoint, Teams, and Purview configuration is not its core. |
| Mature risk scoring and prioritization. | Microsoft-specific compliance mapping is limited. |
| Large ecosystem and integrations. | No agentic remediation of Microsoft 365 misconfigurations. |
| Capability | Tenable | Senserva |
|---|---|---|
| Infrastructure vulnerability scanning | Core strength | Not a vuln scanner |
| M365 configuration posture | Limited | 650+ checks |
| Microsoft 365 patch verification | Partial | Cross-API double-check |
| M365 compliance mapping | Limited | Native |
| Agentic M365 remediation | No | Yes |

Senserva builds a complete, structured Microsoft 365 security dataset, configuration, identity, devices, logs, CVEs, and compliance mappings, as one connected graph, and opens all of it to the AI of your choice through the Claude MCP and the Senserva SDK. Bring your own model, there is no AI markup. Point Claude, or any AI you run, at the whole dataset and it can audit, threat-hunt, explain, and remediate from your real findings, not a vendor summary.
That is the part most tools do not give you. Many have no AI at all, or a closed built-in assistant you cannot point at your own model, or they keep their findings in a dashboard you cannot query. Where a tool does expose its data to your AI, Senserva runs right alongside it and adds the rest of the Microsoft 365 picture. Either way, the data stays with you, nothing is locked in a vendor cloud.
Tenable is best known for Nessus, one of the most widely used vulnerability scanners, and has grown into a full vulnerability and exposure management vendor. Its core competency is discovering assets and the known vulnerabilities (CVEs) they carry.
Tenable Vulnerability Management (cloud) and Tenable One extend scanning into exposure management, correlating vulnerabilities, misconfigurations, and attack paths across IT, cloud, OT, identity, and web apps to prioritize what truly matters.
Tenable enriches findings with CVSS and its own Vulnerability Priority Rating (VPR), which factors in threat intelligence and exploitability so teams remediate the vulnerabilities most likely to be used against them, not just the highest CVSS.
Tenable is a vulnerability and exposure platform spanning infrastructure broadly. For Microsoft 365 specifically, dedicated configuration posture and compliance coverage of Entra ID, Intune, and Purview is a different, complementary lens.
No. Tenable scans infrastructure vulnerabilities; Senserva audits Microsoft 365 configuration posture and verifies patch coverage. They cover different layers.
No agents and no cloud service. Senserva reads your tenant through Microsoft's APIs and runs on Windows or Mac. You can explore the whole product first on the free Advanced Microsoft 365 Security Simulator, with no access to your environment at all.
Yes. The Advanced Microsoft 365 Security Simulator and the game let you explore a full scan, the findings, the AI, and the reports for free. Scanning your own tenant takes a free registration, which unlocks 2 tenants with up to 25 users each, and education institution and nonprofit discounts are available.
Yes. It supports multi-tenant and MSP fleets, with bulk tenant security audits and unified, client-ready reporting across many customers.
Senserva is built for AI from the ground up and also runs fully without it. Turn it on for AI-enhanced reports and to run the product from Claude, or the AI of your choice, via our market-leading MCP. You bring your own model, so there is no AI markup, and the rich data model keeps calls and cost low.
"We believe Senserva provides a great amount of innovation in the Microsoft security world."
