Security

How Hermetry protects organisations, people and devices – isolation, sign-in, device identity, API keys, the AI firewall, audit and privacy.

This section explains the security controls of Hermetry and how to use them well. It is written for administrators, security officers and integrators who must answer “how is this protected?” and “what should we switch on?”. Each page says what is built, what you can set, and what to watch.

A security checklist for a new organisation

  1. Give every owner and admin a passkey, plus a backup passkey. See Two-factor sign-in and passkeys.
  2. Turn on Require two-step verification for every member under Settings > Sign-in Policy once everyone has a second factor.
  3. Keep at least two owners or admins, and give field staff the User role with the IoT operator group.
  4. Keep every device profile on TLS only (port 8883), and list allowed networks for fixed sites. See Device transport security.
  5. Create API keys with the Read only preset where possible, an allowed network, and an expiry. See API key hardening.
  6. Set the audit log retention your compliance rules need, and subscribe to the audit.high_risk webhook.
  7. Review the AI firewall’s Security incidents once a week. See The AI firewall.
