Confidencial Advanced Data Protection vs ManTech EchoMark: Side-by-Side Comparison (2026)

Confidencial Advanced Data Protection

Mid-market and enterprise teams handling unstructured data across hybrid clouds will get the most from Confidencial Advanced Data Protection; its selective encryption at the cell and pixel level lets you protect sensitive information without breaking AI workflows or full-text search, which matters when you can't just block access to the data. The platform covers ID.AM through DE.CM in NIST CSF 2.0, with automated discovery and policy enforcement for HIPAA and PCI workloads built in. Skip this if your team needs native DLP for email and endpoint communications; Confidencial is designed for data at rest and in transit across storage systems, not message interception.

ManTech EchoMark

Mid-market and enterprise teams managing insider risk through document control will find real value in ManTech EchoMark's invisible watermarking; it catches leaks at the source and ties them back to specific users in ways that visible warnings alone don't. The screenshot-resistant watermark embedding and automatic application across email and documents means protection scales without requiring users to opt in. Skip this if your priority is preventing exfiltration before it happens rather than forensic traceability after the fact; EchoMark assumes the leak occurs and focuses on attribution, not interception.
