Is DLP encryption Quantum Proof? Cyber Program & PQC
Verdict
DLP is not a quantum-proof control. When it intercepts TLS, it inherits middlebox and enterprise CA quantum issues; coordinate with network hybrid pilots.
Overview
Data loss prevention often needs visibility into encrypted channels. That creates deliberate classical MITM patterns requiring strong CA custody—and can block hybrid TLS if outdated.
Program inventory focus: DLP middleboxes concentrate classical CA risk (see TLS middleboxes). Typical classical surfaces: DLP inspection TLS interception; Enterprise CAs. Cross-read /security/program and /assessment. Educational only—not compliance advice.
