Eight decision layers

The dashboard summary is not the complete classifier.

Link topology
Visible CTA, hidden trap, pixel, and related-request sequence.
Network identity
Verified crawlers, scanners, mail infrastructure, cloud, and privacy relays.
HTTP client
User-Agent, method, language, accept and Fetch Metadata headers.
Timing & velocity
Delivery latency, rapid bursts, repeated requests and prefetch order.
Browser execution
JavaScript callback, WebDriver, screen and capability consistency.
Interaction
Pointer, touch, keyboard and page dwell evidence.
Contact history
Prior verified-human behavior reduces repeat false positives.
Privacy semantics
Apple and Gmail image loads never become verified human opens.

Detection engine

Sentinel combines independent signals; no weak signal decides a verdict alone.

13 signal families active

Manual template studio

Create or edit a guided template, or optionally provide your own instrumented HTML.

Custom HTML is optional. Use {{SENTINEL_CTA_URL}} for the tracked link. Sentinel can automatically add the pixel and honeypot when their toggles are enabled.

IP intelligence feeds

0 normalized CIDRs in the bounded-prefix index.

Platform settings

Secrets are write-only and never returned by the API.

AI Agent API

Manual monitoring and controls remain available throughout Sentinel. Only this machine-to-machine API requires its separate key.

The key stays in this browser tab. Use HTTPS before transmitting it over an untrusted network.
