HCL BigFix manages and patches endpoints at enterprise scale across nearly every operating system. Senserva is the independent patch double-check and the Microsoft 365 posture layer.
HCL BigFix uses a single intelligent agent and its Fixlet relevance language to patch and manage endpoints across Windows, macOS, Linux, and Unix at very large scale. It is a powerful deployment platform. Senserva complements it with an independent verification of patch coverage through Microsoft's own APIs, plus the Microsoft 365 configuration posture and compliance that an endpoint platform does not cover.

Senserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside HCL BigFix.
HCL BigFix keeps endpoints running and patched. Senserva sits beside it as the independent read on Microsoft patch state: it reads Intune, Defender for Endpoint TVM, and Azure Update Manager through Microsoft’s own APIs, then ranks missing patches by real-world exploitation, not just severity.
| What HCL BigFix does well | Where teams want more |
|---|---|
| A single lightweight agent manages and patches endpoints across Windows, macOS, Linux, and Unix. | Endpoint-focused: Microsoft 365, Intune, Defender, and Entra ID cloud configuration is out of scope. |
| Scales to very large, distributed enterprise estates. | A deployment platform reports its own actions, not an independent cross-tool check. |
| Fixlet relevance language gives precise, real-time targeting. | No native Microsoft 365 compliance mapping such as SCuBA or MCSB. |
| Modules for compliance, inventory, and lifecycle management. | Heavyweight to stand up if the question is cloud configuration posture. |
| Capability | HCL BigFix | Senserva |
|---|---|---|
| Cross-OS endpoint patching at scale | Core strength | Does not deploy |
| Independent patch verification | Self-reported | Cross-tool double-check |
| M365 configuration posture | No | 650+ checks |
| CVE risk ranking | Module dependent | MSRC, CISA KEV, EPSS |
| Setup to answer cloud posture | Heavyweight | No agents, reads APIs |

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.
HCL BigFix, formerly IBM BigFix and originally Tivoli Endpoint Manager, is a long-standing enterprise endpoint management platform. A single intelligent agent and its Fixlet relevance language let it manage and patch endpoints with precise, real-time targeting.
BigFix is built for very large, distributed estates and covers an unusually wide range of operating systems, Windows, macOS, Linux, and Unix, from one console. That breadth and scale are its defining strengths.
BigFix is delivered as modules, Lifecycle, Patch, Compliance, Inventory, and Remediate, so organizations can adopt patch, configuration compliance, software inventory, and remediation as needed within one architecture.
BigFix excels at deploying and managing endpoints. Pairing it with an independent, agentless view of Microsoft 365 configuration posture and a CVE-ranked patch double-check covers the cloud-configuration questions an endpoint platform does not address.
No. BigFix manages and patches endpoints at scale; Senserva independently verifies patch coverage through Microsoft's APIs and adds Microsoft 365 configuration posture and compliance.
Senserva reads patch state through Microsoft's own APIs, Azure Update Manager, Intune via Microsoft Graph, and Defender TVM, so it confirms the result on the device no matter which platform applied the update.
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.
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.
