Email is the lifeblood of business communication, but it is also the primary entry point for cyber attacks. Phishing, malware, business email compromise - these threats arrive in inboxes every day. Protecting your email is protecting your business.
Enable Multi-Factor Authentication
MFA should be mandatory for all email accounts. Even if credentials are stolen, attackers cannot access accounts without the second factor. This single measure blocks the vast majority of account compromise attempts.
Email Filtering and Scanning
Implement robust email filtering that scans incoming messages for malware, phishing attempts, and spam. Modern email security tools use AI and threat intelligence to identify sophisticated attacks that might bypass traditional filters.
Essential Email Security Measures
- SPF, DKIM, and DMARC: These email authentication protocols help prevent spoofing and verify sender identity.
- Link Protection: Tools that scan links in emails and block access to malicious websites.
- Attachment Sandboxing: Automatically analyzes attachments in isolated environments before delivery.
- Email Encryption: Protects sensitive information in transit and at rest.
- Archive and Retention: Proper email archiving for compliance and e-discovery needs.
User Training Is Critical
Technology cannot catch every threat. Train your team to recognize phishing attempts, verify unusual requests through secondary channels, and report suspicious emails. Regular simulated phishing exercises help keep security awareness high.
Handling Sensitive Information
Not everything belongs in email. Establish policies about what information can be sent via email and when encryption is required. Consider secure file sharing platforms for sensitive documents rather than email attachments.
