archTIS NC Protect vs Sentra Accurate Data Discovery & Classification: Side-by-Side Comparison (2026)

archTIS NC Protect

Mid-market and enterprise teams protecting sensitive data across Microsoft 365 and on-premises file shares need archTIS NC Protect's attribute-based access control, which evaluates policy in real time rather than relying on static labels alone. The tool covers NIST PR.AA (access control) and PR.DS (data security) with per-file encryption and dynamic watermarking that adjusts based on user, device, and network context, delivering protection that moves with your data. Skip this if your organization runs primarily on non-Microsoft infrastructure or needs native cloud-only deployment without on-premises file share integration.

Sentra Accurate Data Discovery & Classification

Mid-market and enterprise teams buried under shadow data across multiple clouds need Sentra Accurate Data Discovery & Classification because its proprietary LLM classifies unstructured data with >95% accuracy, eliminating the false positives that tank adoption of weaker rule-based classifiers. The agentless architecture works across AWS, Azure, GCP, and Snowflake without slowing cloud operations, and continuous monitoring actually catches exfiltration attempts instead of just cataloging what you already know exists. Skip this if your primary need is access governance; Sentra's strength is finding and classifying hidden data, not orchestrating least-privilege controls across identity systems.
