Why Security Teams Are Replacing BigID With Sentra.

BigID moves your data to its SaaS platform and takes months to deploy. Sentra scans in-place with under 3% false positives — and delivers results in days.

4 Reasons Security Teams Switch from BigID to Sentra

Advantage
Install in Minutes, See Value Instantly
Low Operational Cost at Petabyte Scale

AI-Powered Classification Accuracy Using Rich Context
Real-Time Risk Reduction

Sentra
Instant Deployment, Instant Insights

Agentless and API-based, Sentra scans data in-place without moving or copying—delivering results in days, not months.

Built for Scale, Without the Cost

Sentra is highly efficient, scanning with <3% false positives while using minimal compute—ideal for petabyte-scale environments.

Contextual Intelligence That Learns

Uses AI/ML and composite classifiers with rich context across identity, access, and environment—finding toxic data combinations and enforcing labels like M365 MIP.

Intelligent Risk Scoring and Data Threat Detection

Prioritizes risk with real-time DDR, anomaly monitoring, and access/movement mapping to prevent breach, GenAI data loss, and toxic sprawl.

BigID

Requires connector setup and moves data to its SaaS platform, complicating deployment and slowing time to value.

Relies on brute-force sampling and heavy compute, making scanning slow, costly, and difficult to scale.

Classifiers are often ineffective (only ~25 perform well), with high false negatives. Limited context and no differentiation between structured and unstructured data.

No DDR capabilities, and cannot track access or data movement effectively.
