Audit trail & diary
A tamper-evident log for auditors. A daily diary for engineers. A fault register that spots the problems that keep coming back.

Every command, approval, refusal and result, timestamped and hash-chained. Alter, delete or reorder an entry and the chain breaks visibly. Copies can go to your own log server.
What was done, what broke, what’s waiting for approval and what’s planned for tomorrow, written so any engineer can pick up where Guardian left off.
Open and closed faults, time to fix, and repeat offenders, like the third link drop on the same PC this month.
Weekly and monthly reports and change records for clients, auditors and insurers, covering Cyber Essentials, ISO 27001 and GDPR evidence.
Guardian can only mark an incident resolved when the system itself re-runs the original fault check after the last change, and it passes. Faults that come and go stay under watch until they’ve stayed fixed.
