Email impersonation and business email compromise (BEC) form the starting point for over 90% of successful corporate network breaches.
Technical depth and operational guidance
Without correct DNS controls, any external server can send emails claiming to originate from your business domain, allowing attackers to target your clients, employees, and partners with highly convincing phishing campaigns.
Protecting your domain requires configuring a triad of DNS safeguards: SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).
SPF lists authorized mailing IP ranges. DKIM provides cryptographic signatures proving the email hasn't been altered. DMARC tells the receiving server how to handle messages that fail SPF/DKIM verification, with a final goal of 'reject' to completely block spoofed mails.
