Zero-Logs Posture
Compliance monitoring often touches sensitive pages and datasets. Keep run history out of vendor logs.
Use Case Compliance monitoring
Compliance monitoring
with evidence
Monitor policy pages, disclosures, and regulated content changes without drowning in diff noise. When a policy updates, automatically capture screenshot proof and route the alert to a reviewer.
Deterministic Extraction
Normalize pages into markdown so “diff noise” doesn’t overwhelm real policy changes.
Stealth For Guarded Pages
Many compliance pages sit behind bot walls, geo gates, or WAF rules. Stealth defaults keep monitors alive.
Evidence Capture
When something changes, capture a screenshot/PDF as an audit artifact for review.
BYOP When Required
For strict enterprise routing, bring your own proxy (BYOP) while keeping the same API and semantics.
Escalate To Sessions
If a page requires login or multi-step flow, switch to Sessions (Playwright connect) without changing vendors.
Monitor changes with hashes
Extract markdown, hash it, store the hash, and alert when it changes. When alerts fire, pair them with a screenshot/PDF.
