Centri · BTL2
Develop skills in security, blue-team with Blue Team Level 2. Review the official objectives and practical assessment requirements.
Official lookup
Search the official directory by the holder's name or certificate ID. Centri also covers the former Security Blue Team credentials. Check the exact certification shown in the result.
If your award has a public Credly badge, you can import its URL. CertSprout automatically checks supported Credly and Microsoft Learn records. Provider-site lookups and manually attached links do not automatically mark a credential verified. A public record confirms the award; it does not prove the signed-in user owns it.
