Cloud exposure remediation that proves each fix safe before it runs

Tamnoon is a remediation platform for cloud exposures—the misconfigurations and other findings that security tools detect but teams leave open.

Much of that backlog persists because every production change needs someone to sign off on it, and few teams will switch on automation they cannot explain to a change board.

To remedy this Tamnoon’s engine checks each proposed fix against your environment and runs only the ones it can show are safe, and sends them through your existing change process with a rollback ready to go if needed.

When it cannot establish that a change is safe, it declines in writing, with the evidence behind the decision which includes what would change the outcome and the steps to apply the fix by hand.

The security team keeps the final say on every change.

The engine’s judgment draws on years of engineer reviews of remediations across Tamnoon’s customer base, then applies stricter rules to each individual environment.

It works with the scanners and cloud security tools a team already runs across AWS, Azure, and GCP, and connects in about 30 minutes with read-only access and nothing installed.

Tamnoon reports that one customer cut its open findings to a third over four quarters, and that another brought the cost per finding to one-eleventh of manual remediation.

The company was founded in 2021 and has raised more than $18 million, including a $12 million Series A in 2024 and a $5.1 million seed round in 2023.
