Turn on security

Security can only act on members whose highest role is below Element's. To protect the server from a compromised admin, Element's role needs to be above theirs.

In Server Settings › Roles, drag Element's role to the top, or as close as you can.

Run /security settings. The overview lists every module and whether it's on. Every module starts off, so nothing happens until you switch one on.

Only the server owner can open it at first.

Open the Logging page and pick where each kind of event is logged. With logging on, you can see what the other modules would do before trusting them with your members.

On the Authority members page, add your co-owners as Extra Owners (up to 5) and your most trusted admins as Trusted Admins (up to 8). They can change Security's settings.

Open Anti Nuke and switch it on. It watches for destructive actions, like mass bans or channel deletions, by members or bots, and quarantines whoever does them.

Then add the rest you need, one at a time: Anti Raid, Join Gate and Verification for new members, Auto Mod for spam, and so on. The security page lists what each does.

If a trusted bot or channel keeps setting a module off, run /security whitelist with it. Pick only the checks it needs to skip, and give a duration if it's temporary.

/mod quarantine and /mod unquarantine quarantine a member by hand, and /security lastactions shows recent audit log actions when you need to see who did what.
