One trial per company. Trials run Shield Defend with blocking enabled from first boot — the license entitlement turns it on automatically.
Your Shield Defend license key
1. Install Shield on your server
Run this on a fresh Linux box (Amazon Linux 2023, Ubuntu, or any Docker host). Add a domain you control as the second argument to get automatic HTTPS.
New to Docker, or want HTTPS and troubleshooting? See the full install guide.
2. Add the Chrome extension
Install “Shield by Cinder Labs” from the Chrome Web Store on each user's browser (or push it org-wide via Chrome's ExtensionInstallForcelist policy), then point it at your Shield server URL.
3. Open Shield & create your admin account
Browse to your server (http://your-server-ip or your HTTPS domain) and register the first admin user. Blocking is on from the start.
