Deprecated TLS/SSL protocol versions (SSLv2, SSLv3, TLS 1.0, TLS 1.1) are vulnerable to downgrade and cipher attacks, fail PCI-DSS, and are rejected by up-to-date browsers and API clients.
A scan reports where your tenant stands on this check — pass, fail with a step-by-step fix, or not applicable if your licensing doesn’t include the feature. When Tenant Strike can’t read a setting with read-only access, it says unverified and gives you a one-command way to confirm it yourself — it never guesses.
