SonicWall AVANAN DMARC Add-On 1 Yr Per License | Email Security

Strengthen email trust at the domain level with a 1-year AVANAN DMARC add-on license for SonicWall. Built for organizations that need clearer control over sender authentication, this subscription helps reduce spoofing, phishing impersonation, and unauthorized domain use without adding operational complexity. DMARC gives security and messaging teams the policy framework they need to validate legitimate mail streams and act on failures with confidence. For enterprises managing multiple domains or high-value brands, that means better visibility into authentication results and a more disciplined path to enforcement. It is a practical fit for teams that want to harden email identity controls while keeping administration focused and predictable. As an add-on license, this offering is designed to extend SonicWall’s email security posture with a defined 1-year term. It is well suited for procurement cycles that prefer annual renewal control and for IT teams that need a targeted security layer rather than a broad platform change. When email impersonation carries real business risk, DMARC is one of the most direct ways to protect sender reputation and support policy-driven defense.
