Turn Sensitive Data Visibility into Action

Understand exactly where sensitive and PII data exists across your APIs. Uncover hidden exposures, prioritize the highest risks, and protect the data that matters most to your business.

See Sensitive Data Discovery in Action

Every API Call Is a New Place for Data to Hide

Every new endpoint can expose sensitive data. AppSentinels finds, classifies, and tracks it automatically, giving you complete visibility across your API ecosystem.

AI-Powered Classification

  • Near-zero false positives: Our AI classification engine identifies sensitive data points across structured and unstructured payloads without flooding your team with noise.
  • Context-aware detection: Data is read in context, not matched on pattern alone, so lookalike fields never get mistaken for regulated data.
  • Structured and unstructured coverage: JSON bodies, headers, logs, and free-text fields are all classified, not just tabular schemas.
  • Continuous re-classification: As APIs evolve, classification updates automatically instead of going stale.

Region-Specific Compliance Coverage

  • 60+ built-in recognizers: Pre-mapped to the regulations your business actually operates under, ready out of the box.
  • Global regulation mapping: GDPR, CCPA, PCI-DSS, DPDP, and more are covered without custom rule-building.
  • Jurisdiction-aware flagging: Data is evaluated against the compliance regime tied to its region, not a single global standard.
  • Audit-ready evidence: Compliance mapping doubles as documentation your audit team can hand over directly.

Custom Data Recognizers

  • Proprietary data protection: Define recognizers for data types unique to your business that no off-the-shelf tool would catch.
  • Industry-specific patterns: Build recognizers around the identifiers and formats specific to your sector.
  • Business-critical field tracking: Track internal IDs, contract data, and trade secrets with the same rigor as regulated PII.
  • No-code rule definition: Recognizers are configured, not coded, so security teams stay in control without engineering dependencies.

Real-Time Monitoring & Risk Reduction

  • Continuous API-wide scanning: Every endpoint is monitored as data moves, not audited on a quarterly cycle.
  • Exposure alerts: Sensitive data appearing in an unexpected endpoint, response, or third-party call triggers an immediate alert.
  • Data flow mapping: See exactly where sensitive data enters, transforms, and exits your API ecosystem.
  • Risk-prioritized visibility: Findings are ranked by exposure severity, so teams fix what matters first.

Frequently Asked Questions

What is sensitive data discovery in API security?
Sensitive data discovery is the continuous process of identifying, classifying, and tracking PII, PHI, payment data, and other regulated information as it moves through API requests and responses. AppSentinels does this automatically across your full API ecosystem instead of relying on periodic manual audits.
AppSentinels uses AI-powered classification that reads data in context rather than matching surface-level patterns, distinguishing genuine sensitive fields from lookalike values so security teams aren’t chasing noise.
AppSentinels ships with 60+ built-in, region-specific recognizers mapped to regulations including GDPR, CCPA, PCI-DSS, and DPDP, with coverage expanding as new regulations emerge.
Yes. AppSentinels lets teams define custom data recognizers for proprietary datasets, industry-specific identifiers, and other business-critical information that generic classifiers won’t catch.
Yes. AppSentinels continuously monitors your API ecosystem so newly exposed sensitive data is flagged the moment it appears, rather than surfacing weeks later during the next audit cycle.
