About this tag
The bitlocker security tag covers discussions about the real-world risks and limitations of Microsoft's BitLocker encryption, including vulnerabilities like CVE-2026-45655 and CVE-2025-48804 that can bypass protection on physically accessible devices. Topics include TPM-only deployment weaknesses, key escrow concerns when cloud providers hold recovery keys, and practical guidance for securely wiping BitLocker-protected drives before device handoff. The content emphasizes that BitLocker is not a silver bullet and that administrators must consider physical attack vectors, patch management, and key custody to maintain data protection.
