#### ⭐ Highlight Feature: **2FA Lock**

A fully custom **on-Discord 2FA system** (Google Authenticator or similar) that locks down critical actions such as:

* Announcements
* Event management
* Server alterations
* Maintenance work

Even if a team member is hacked, your community remains protected.\
This is the gold standard of Discord security in Web3.

💡 *Site Note:* Most exploit attacks happen through compromised team accounts. This single feature eliminates that entire threat vector.

***

#### 🔒 Automod (Enhanced)

Sentinel enhances Discord’s native automod by adding:

* Scam-text format block
* Mixed-format message detection
* Markdown & disguised-link detection
* Global signature library informed by **80+ Web3 communities**

New scam techniques are automatically blocked across all Sentinel servers.

***

#### 🥸 Impersonation Protection

Sentinel detects:

* Fake “team clones”
* Copycat usernames
* Stolen profile images
* Approximated impersonators

The bot continuously monitors team profiles and:

* Flags suspicious accounts
* Suggests automated bans
* Can quarantine or verify decisions instantly

{% hint style="info" %}
⚠️ *Warning:* Impersonation scams are the #1 cause of wallet drains in community channels.
{% endhint %}

#### 💽 Server Backup

A full disaster recovery system:

* Structure, roles, and permissions backup
* Up to **30 messages** saved in **5 channels**
* One-click restore
* Messages recreated via webhook with original name + PFP for authenticity

Ideal for server wipes, raids, or emergency rebuilds.

#### 🤖 Captcha System

Replace tools like Pandez with a fully customizable verification layer:

* Familiar number pad captcha
* Custom text
* Optional images
* Clean UI with no cross-promotions

Fits perfectly with branding for any Web3 project.

***

#### 🗣️ Disable Server DMs

Permanently enforce Discord’s “friends-only DMs” rule server-wide:

* Blocks unsolicited direct messages between non-friends
* Protects new joiners from phishing and scam DMs
* Removes the most common scam vector in Web3 communities

***

#### 🛠️ *Beta Feature:* Cross-Server Bans

Ban malicious users across **all servers you manage** simultaneously.

Perfect for agencies handling multiple client communities.
