Synapse Edge Defense

# Data Loss Prevention at the Edge

Inline response inspection. Real-time blocking. Zero additional latency. Sensitive data never leaves your infrastructure unprotected.

API
Custom Patterns
Organization-specific regex patterns via API — internal IDs, proprietary formats, domain-specific data. Fully configurable per site.

Action
Block / Mask / Log / Alert
Response Actions
Block
Replace entire response with error. Sensitive data never transmitted.
Mask
Redact matched patterns in-flight. Response delivered with data obscured.
Log
Record detection event for audit. Response passes through unmodified.
Alert
Generate real-time notification. SOC visibility without blocking traffic.
Architecture — Why Edge DLP Matters
Traditional DLP
Multiple hops, added latency, blind spots. Response passes through — data exfiltrated. Breach discovered 200+ days later via audit.
✗ BREACH
Synapse Edge DLP
Single hop, inline inspection, real-time blocking. 847 SSNs, 10,000 emails detected. Action: BLOCK + Alert + Actor risk +85.
✓ BLOCKED
Detection Examples
Social Security Number
{"user": {"ssn": "123-45-6789", "name": "John"}}
⚠ SSN pattern detected in response
Pattern: \b\d{3}-\d{2}-\d{4}\b
Action: Block + Log + Actor risk +25
Credit Card Number
{"payment": {"card": "4532015112830366"}}
⚠ Valid credit card (Luhn check passed)
Pattern: 16-digit + Luhn validation
Action: Block + Alert + PCI flag
AWS Secret Key
{"config": {"aws_secret": "wJalrXUtnFEMI/K7MDENG..."}}
⚠ AWS secret access key pattern
Pattern: High entropy + known prefix
Action: Block + Critical alert + Incident
Edge Advantages
Response Body Inspection
Not just headers — full payload analysis. JSON, XML, HTML, raw bytes.
Inline Blocking
Block before data leaves the edge. Not detect-and-alert-later.
Zero Additional Latency
DLP runs in the WAF decision path. No separate proxy hop required.
Actor Correlation
DLP violations affect actor risk scores. Cross-session behavioral memory.
