+# Domain Squatting Detection
+
+Domain squatting protection helps keep you safe from fake websites that try to trick you by using look-alike domain names. Attackers create these fake domains to steal your login credentials.
+
+## What is Domain Squatting?
+
+Domain squatting (sometimes called "typosquatting") is when attackers register website addresses that are intentionally similar to legitimate sites. For example:
+
+- `micros0ft.com` (using a zero instead of the letter O)
+- `microsоft.com` (using a Cyrillic "о" that looks like an English "o")
+- `login-microsoft.com` (adding extra words to a real domain)
+
+These fake sites often look exactly like the real Microsoft login page, but they're designed to capture your username and password.
+
+## How Check Protects You
+
+Check automatically watches for these fake domains using four smart detection methods:
+
+### 1. **Character Difference Detection**
+Spots domains where characters are changed, missing, or swapped around.
+
+**Examples Check catches:**
+- `microsft.com` → missing the letter "o"
+- `micorsoft.com` → letters swapped ("or" instead of "ro")
+- `microosoft.com` → extra letter added
+
+### 2. **Look-Alike Character Detection**
+Finds domains using special characters that look similar to normal letters.
+
+**Examples Check catches:**
+- `micrоsoft.com` → uses a Cyrillic "о" that looks like an English "o"
+- `microsоft.com` → mixes different alphabet characters
+- `micro𝐬oft.com` → uses special Unicode characters
+
+### 3. **Typing Mistake Detection**
+Identifies domains based on common typing errors and keyboard slip-ups.
+
+**Examples Check catches:**
+- `micrisoft.com` → finger slipped to nearby key
+- `microssoft.com` → double-typed a letter
+- `microosft.com` → typo mixing up letters
+
+### 4. **Suspicious Word Combination Detection**
+Spots domains that add words before or after legitimate domains to look more official.
+
+**Examples Check catches:**
+- `secure-microsoft.com`
+- `login-microsoft-verify.com`
+- `microsoft-auth.com`
+- `official-microsoft-support.com`
+
+Common suspicious words attackers use: `login`, `secure`, `verify`, `official`, `support`, `auth`, `signin`, `portal`
+
+## What Domains Are Protected?
+
+Check protects **30+ popular domains** by default, including:
+
+**Microsoft Services:**
+- microsoft.com, microsoftonline.com, office.com, outlook.com, onedrive.com, and more
+
+**Other Popular Services:**
+- google.com, github.com, facebook.com, amazon.com, apple.com, paypal.com, and more
+
+**Plus: Your URL Allowlist**
+
+{% hint style="info" %}
+**Unified Protection:** Check uses your [URL Allowlist](../settings/detection-rules.md#url-allowlist-regex-or-url-with-wildcards) for double protection. Any domains you add there are automatically protected from squatting attempts too!
+
+For example, if you add `https://yourcompany.com/*` to your allowlist, Check will also protect against fake domains like `yourcompany.net` or `your-company.com`.
+{% endhint %}
+
+## How It Works in Practice
+
+When you visit a website, Check automatically:
+
+1. **Checks** if the domain looks similar to any protected domain
+2. **Analyzes** using all four detection methods
+3. **Warns** you if it finds a suspicious match
+4. **Blocks** the page if it's clearly a phishing attempt
+
+You don't need to do anything - the protection works automatically in the background!
+
+## Configuration
+
+{% hint style="warning" %}
+**For most users**: Domain squatting detection works automatically with default settings. You don't need to change anything!
+{% endhint %}
+
+### Page Blocking Control
+
+Check has an **"Enable Page Blocking"** setting in the extension options that controls how suspicious pages are handled:
+
+- **Page Blocking Enabled** + **Action: "block"** = Page is completely blocked with full-page warning
+- **Page Blocking Enabled** + **Action: "warn"** = Warning banner shown, page remains accessible
+- **Page Blocking Disabled** = Warning banner shown regardless of action setting (never blocks)
+
+This gives you control over whether you want aggressive blocking or just warnings for suspicious domains.
+
+### For Advanced Users and IT Departments
+
+Domain squatting detection is configured in your detection rules file (not in the Settings UI). This follows the same pattern as other advanced security features like Rogue Apps Detection.
+
+#### How to Configure
+
+Edit your `rules/detection-rules.json` file to customize:
+
+**Enable/Disable Detection:**
+```json
+{
+  "domain_squatting": {
+    "enabled": true,  // Turn detection on/off
+    "action": "block" // Action when detected: "block" or "warn"
+  }
+}
+```
+
+**Set Action Type:**
+```json
+{
+  "domain_squatting": {
+    "action": "block"  // "block" = full page block, "warn" = banner only
+  }
+}
+```
+Note: Page blocking also requires "Enable Page Blocking" to be turned ON in settings.
+
+**Adjust Sensitivity:**
+    "enabled": true
+  }
+}
+```
+
+**Adjust Sensitivity** (how strict the checking is):
+```json
+{
+  "domain_squatting": {
+    "deviation_threshold": 2
+  }
+}
+```
+- Lower numbers (1) = Very strict, catches fewer variations
+- Higher numbers (3-5) = More lenient, catches more variations
+- Default is 2 (recommended for most organizations)
+
+**Choose Detection Methods:**
+```json
+{
+  "domain_squatting": {
+    "algorithms": {
+      "levenshtein": true,
+      "homoglyph": true,
+      "typosquat": true,
+      "combosquat": true
+    }
+  }
+}
+```
+
+You can turn individual detection methods on/off. We recommend keeping all four enabled for maximum protection.
+
+## For MSPs and Enterprise IT
+
+### Enterprise Policy Management
+
+Domain squatting detection can be managed through Group Policy (GPO) or Microsoft Intune, just like other Check settings.
+
+**What You Can Control via Policy:**
+- Detection sensitivity (character difference threshold)
+- Which detection methods are active
+- Additional protected domains specific to your organization
+
+**What's in the Rules File:**
+- Enable/disable domain squatting detection
+- Default protected domains list
+- Detection rules and patterns
+
+This separation gives you flexibility - you control the core security settings through your detection rules file, while still allowing policy-based customization for different clients or departments.
+
+### Adding Organization-Specific Domains
+
+{% hint style="info" %}
+**Use the URL Allowlist!** 
+
+The easiest way to protect your organization's domains is to add them to the URL Allowlist in Detection Rules settings. This automatically:
+1. Prevents false positives on your internal sites
+2. Protects those domains from squatting attempts
+3. Works without modifying detection rules files
+{% endhint %}
+
+**Example:** Adding `https://contoso.com/*` to your allowlist protects against fake domains like:
+- `cont0so.com` (zero instead of o)
+- `contos0.com` (zero at the end)
+- `login-contoso.com` (suspicious prefix)
+
+### CIPP Reporting and Webhooks
+
+Domain squatting detections are automatically reported through your existing Check monitoring:
+
+- **Activity Logs**: View all domain squatting warnings and blocks
+- **CIPP Integration**: Squatting detections appear in your CIPP logbook
+- **Webhooks**: Configure webhooks to receive `domain_squatting_detected` events
+
+See [General Settings](../settings/general.md) for configuring reporting and webhooks.
+
+## Troubleshooting
+
+### "Check blocked a legitimate site"
+
+If Check blocks a site you trust:
+
+1. **Add it to your URL Allowlist** in Detection Rules settings
+2. The site will be both allowed and protected from squatting
+3. Report the false positive to help improve Check
+
+### "A phishing site wasn't detected"
+
+Domain squatting detection works alongside Check's other phishing protections. If a site gets through:
+
+1. Use "Report False Negative" if you encounter a phishing site
+2. Check will update rules to catch it in the future
+3. Your report helps protect the entire community
+
+### "Settings are grayed out"
+
+If you can't see or change domain squatting settings, your IT department has configured these centrally. This is normal for managed deployments - contact your IT team if you need adjustments.
