The Trench Guard - Protect your business from Phishing

🛡️ PROTECT YOUR BUSINESS FROM PHISHING ATTACKS

The Trench Guard is your shield against fraudulent emails. Automatically detects identity spoofing attempts while you read your mail in Gmail and Outlook.

✅ WHAT IT DOES

Analyzes every email you receive and instantly alerts you if it detects:
- Senders impersonating your company emails
- Domains similar to legitimate ones (example: micr0soft.com instead of microsoft.com)
- Suspicious characters that look like normal letters but aren't
- Known users using unauthorized external domains

🎯 KEY BENEFITS
