How Defendr stops a scam link
Scroll, and the example plays step by step. This is what a real case looks like.
Skip the example- A message arrivesAn account posts a free Nitro link in #general. It may have been taken over.
- Defendr checks the linkThe domain is on Defendr's reviewed threat list. That takes a split second, so the chat looks the same.
- The message goesDefendr deletes it, gives the account a one-hour timeout and explains why in a direct message. A short notice in the channel disappears again after a few seconds.
- Your team sees whyIn #defendr-logs your team sees the case with the reason, and buttons to report a false positive, revert the timeout or add a note.
Example in four steps. A member's account posts a free Nitro link in #general. The link is on Defendr's reviewed threat list. Defendr deletes the message, gives the account a one-hour timeout, explains why in a direct message and posts a short notice in the channel that disappears again after a few seconds. In #defendr-logs your team sees case 1042 with the reason and buttons to report a false positive, revert the timeout or add a note.

False positiveRevertNote
15 modules. One calm setup.
Every module starts with sensible defaults. Pick one to see what it does.
Every case comes with a reason and a way back
Case
A case shows the member, the rule and every step Defendr took.
Why?
Plain reasons, not a score: which list, which pattern, which limit.
Undo
One click lifts a timeout, a ban or a quarantine role. If Defendr got it wrong, mark the case as a false positive, and Defendr asks its team to check the match.
Appeal
Appeals are on by default: members can ask for a second look and see by when they get an answer. Appeal a decision
Start gently, get strict when you need it
Three levels cover most servers. Add-ons tune them for your kind of community, and you can change every single value later.
Logs everything, never deletes or punishes. Good for a trial.
Deletes confirmed threats, times out hijacked accounts, pauses invites during raids.
Stronger actions for reviewed threats and a join gate for new accounts.

- Sell or share your dataNothing goes to advertisers, analytics services or data brokers.
- Keep messages it did not act onMessages are checked in memory for a moment. Only when Defendr acts on one does it keep a sealed copy with the case for the team's review, deleted 90 days after the case is closed.
- Send welcome or advertising messagesMembers only hear from Defendr when an action concerns them.
- Charge for safetyAll protection is free, and it stays free. There is no paid tier for safety.
No ads. No trackers. No cookie banner, because there is nothing to consent to.

Built and run independently in Germany
Independent, based in Germany and reachable directly. The rules Defendr follows are public, and so is every change to them.
Questions people ask first
Is Defendr free?
Yes. All protection is free of charge, and there is no paid tier for safety: every module, every protection level and the website are free for every server.
Which permissions does Defendr need?
Only the ones its enabled modules use, and never Administrator. When you add Defendr, Standard asks for the permissions the protection modules need, for example Manage Messages to delete a scam and Timeout Members for timeouts. Full also asks for Manage Channels to lock channels down and Manage Webhooks to follow the update channel.
Presets and add-ons
A preset sets every value at once: Monitor-only logs without acting, Recommended acts on clear threats, Strict acts early. Add-ons for community, gaming and crypto servers adjust a few values. Your own settings stay on top. Defendr never changes behaviour on its own: new preset versions wait for your decision.
What happens if Defendr gets it wrong?
Every case shows its reasons. A moderator can press False positive: Defendr lifts a timeout, a ban or a quarantine role and asks its team to review the match. Members can appeal with /appeal while the server keeps appeals on (the default), and a reviewer who was not involved answers by direct message within 14 days.
Appeals
If Defendr or a server acted on you, you can ask for a review with /appeal: appeals are on by default. A reviewer who was not involved in the original decision looks at it and answers by DM within 14 days.
Does Defendr store my messages?
Only what is needed to check a case. Message content is checked in memory for a moment. When Defendr acts on a message, for example deletes it, it keeps a sealed copy with the moderation case so the Defendr team can check the case and an appeal fairly; only the team can open it, and it is deleted 90 days after the case is closed or the appeal is decided. Detection records and moderation cases keep IDs, the type of match and the action taken. Only if a server turns it on, a short, defanged excerpt is kept with a case. Two things are kept so the team can answer you: what you write to Defendr by direct message, and the conversation in your support tickets on the Defendr support server. When someone reports a message to the Defendr team, a sealed copy of that message is kept for the review, until 90 days after the decision.
How is Defendr different from Discord AutoMod?
Defendr can create a word filter in Discord's AutoMod for you: Discord holds back messages with hateful or sexual words before anyone sees them, and Defendr adds a case. Discord AutoMod blocks messages by keywords, mention counts and Discord's own spam filter. Defendr adds what keyword rules cannot see: links on known threat lists, known scam images, hijacked accounts, raids and nuke attempts, and for each of its own actions a case with the reasons. One click lifts a timeout or a ban, and appeals are on by default. Both work side by side, and Defendr's Security Score checks that a mention-spam AutoMod rule exists.
Who runs Defendr?
Defendr is built and run by an independent operator in Germany. It is not affiliated with or endorsed by Discord Inc. The legal notice (Impressum) names the operator and how to reach them.
