​
Schema & Key Analytics

Your schema, under surveillance. Continuous monitoring of your data’s shape. DataHarbor learns schema over time and surfaces emerging risks automatically.

​
How it works

As Virtual APIs are used, DataHarbor:
  1. Learns schema shape over time
  2. Detects net-new fields as they appear
  3. Flags uncovered keys that may contain sensitive data
  4. Identifies risky combinations that enable re-identification
  5. Surfaces compliance violations

​
Net-new field detection

When your upstream API adds new fields, DataHarbor notices: 
{
  "alert": "new_field_detected",
  "virtual_api": "partner-view",
  "field": "emergency_contact_phone",
  "first_seen": "2025-01-15T10:30:00Z",
  "sample_value_type": "string",
  "suggested_action": "review_for_pii"
}
New fields are not automatically protected. You receive an alert to review and apply appropriate controls.

​
Uncovered key detection

DataHarbor flags fields that may contain sensitive data but have no controls applied: 
{
  "alert": "uncovered_sensitive_field",
  "virtual_api": "partner-view",
  "field": "drivers_license",
  "confidence": 0.92,
  "reason": "Field name matches known PII pattern",
  "suggested_control": "redact"
}

​
Risky combination detection

Some field combinations enable re-identification even when individual fields seem safe: 
{
  "alert": "risky_combination",
  "virtual_api": "analytics-view",
  "fields": ["zip_code", "date_of_birth", "gender"],
  "risk": "high",
  "reason": "Combination can identify 87% of US population",
  "reference": "Sweeney 2000",
  "suggested_action": "anonymize_or_generalize"
}

​
Compliance detection

Automatic detection of potential compliance violations:
RegulationDetection
GDPR Article 4(1)Personal data exposed without consent basis
CCPACalifornia resident PII without disclosure
HIPAAPHI fields without BAA coverage
{
  "alert": "compliance_risk",
  "virtual_api": "partner-view",
  "regulation": "GDPR",
  "article": "4(1)",
  "issue": "email field exposed to non-EU processor",
  "suggested_action": "apply_tokenization_or_consent"
}

​
Dashboard view

The Schema Analytics dashboard shows:
  • Schema coverage: Percentage of fields with controls applied
  • Risk score: Aggregate risk based on uncovered and risky fields
  • Field inventory: Complete list of observed fields with control status
  • Alert history: Timeline of detected issues
