QENEX Pulse — the same scanner, every business day, for your whole vendor portfolio

One-off scans like this one are useful, but auditors increasingly ask "prove this score was true on 14 November 2024". QENEX Pulse runs these nine checks plus tougher ones (sub-processor watch, contract- term capture, regulator-mapped reports) on every vendor your firm depends on, every day, with each result SHA-256 hashed and anchored into IPFS + OpenTimestamps. From £79/month for 10 vendors.

Why this is free. This scanner is free because it's the entry point to QENEX Pulse — continuous, anchored vendor monitoring from £79/mo. We don't run ads. We don't sell your scan data. The scanner runs entirely on QENEX-owned bare-metal infrastructure in London with no third-party tracking in the request path.
