Key protections
The foundations of secure email.
Sender authentication
SPF, DKIM and DMARC work together to validate sending domains and reduce spoofing and impersonation.
Spam and threat filtering
Filtering tools help identify malicious links, unwanted messages and suspicious attachments.
Access & recovery
Security is an ongoing process.
Strong authentication, preferably phishing-resistant MFA, account monitoring, recovery planning and regular updates help keep email systems protected.
