About Tamnoon
Tamnoon sells software that closes cloud security findings. It sits downstream of the scanners a customer already runs, such as Wiz, CrowdStrike, Orca and Defender for Cloud, and works on the alerts those tools produce. Its customers are enterprise security and cloud teams with large backlogs of open findings. The engine, called Tami, investigates each finding in read-only mode and returns one of three verdicts. Safe fixes run through the customer's own change process and are rescanned until clean. Anything it cannot prove safe is refused in writing with the evidence attached. Context such as usage, ownership and blast radius drives the decision rather than severity alone. Every decision is kept as a record showing the verdict, the evidence, who approved and what ran. Fixes are written to survive later infrastructure-as-code applies, and each one comes with a guardrail to stop the same issue returning. Tamnoon was founded in 2021.
