The platform

One layer of defence across every server you run

Detection, escalation and evidence in one place — with a public registry your whole network shares.

Real-time protection

A constantly updated threat registry, automated detection and instant escalation — so raids and scammers are stopped before your team wakes up.

  • Cross-server flag propagation
  • Automated joins & alt screening
  • Full moderator audit trail

Fully customisable

Tune moderation rules, logging and filters per server with /settings and a clean web dashboard.

Privacy first

Evidence stays with the Sentinel team. We never sell or resell data about your server or its members.

Built for developers

Query the registry straight from your own stack, FiveM resource or Roblox game with a free API key.

  • Shared evidence, reviewed by humans before it lands
  • Appeals handled openly, with a public paper trail
  • One dashboard for every server you moderate
