BackHow Rotate Detects Fake Senders and Protects Your Inbox
How Rotate Identifies Fake Senders
Rotate employs multiple layers of detection to ensure that only legitimate emails are delivered:
1. Email Authentication Enforcement
- DMARC (Domain-based Message Authentication, Reporting, and Conformance) – Ensures emails claiming to be from a domain are authenticated before reaching recipients.
- SPF (Sender Policy Framework) – Verifies whether the email was sent from an authorized mail server.
- DKIM (DomainKeys Identified Mail) – Uses cryptographic signatures to confirm email integrity and legitimacy.
2. Sender Reputation Analysis
- Rotate maintains a dynamic reputation database for email senders, flagging suspicious domains or those associated with fraudulent activity.
- Behavioral analysis helps detect anomalies, such as unexpected email patterns from a known contact.
3. Header and Metadata Inspection
- Identifies inconsistencies in email headers, such as mismatched "From" and "Reply-To" addresses, which are common in spoofing attempts.
- Detects signs of display name spoofing, where attackers use misleading names to appear as trusted senders.
4. Content and Contextual Analysis
- AI-powered analysis scans for phishing indicators, urgent requests for sensitive data, and other social engineering tactics.
- URL and attachment scanning prevent malicious links and files from reaching the recipient.
5. Real-Time Threat Intelligence
- Rotate integrates with global threat intelligence feeds to identify known phishing campaigns and malicious sender domains.
- Continuous updates ensure protection against emerging email-based threats.
Frequently Asked Questions
What is the Email Add-On?
The Email Add-On is a tool designed for Gmail and Outlook that helps you identify and manage malicious emails, including spam, phishing attempts, and malware. It enhances your email security by reporting suspicious emails and managing your personal spam list.
Why are mail rules a security risk?
Mail rules can be exploited to exfiltrate data, hide security alerts, or modify incoming messages. Attackers often use forwarding rules to silently send emails to external accounts or create rules that auto-delete security notifications, making it harder to detect compromises.
Why is email security important?
Email is a common attack vector for phishing, spoofing, and other cyber threats. Properly configured DMARC, DKIM, and SPF records help prevent unauthorized parties from sending emails on behalf of your domain, protecting your organization from email-based attacks.
