Executive Summary

Tamnoon sells managed remediation for cloud security findings. Its AI agent Tami triages and investigates the alerts that tools such as Wiz and Orca Security raise, and its cloud experts validate the fixes or execute them in the customer's environment. Its founders came from Dome9, which Check Point acquired, started Tamnoon in 2022, name Warner Music Group a customer, and won a public endorsement from Nextracker's security chief. Two findings stand out. Tamnoon distributes through the CNAPP ecosystems it depends on, and Wiz, its flagship partner, now ships a remediation agent of its own. And while its experts change configurations inside customer production clouds, its site exposes only an image-only SOC 2 badge, with no trust portal or downloadable report.
