SonicWall DNS Security Service for TZ280P 4YR | DNS Protection, Support

Stop DNS-layer attacks before they turn into incidents. SonicWall DNS Security Service for TZ280P adds a dedicated protection layer that inspects DNS requests for signs of malicious activity, helping block access to harmful domains and reduce exposure to phishing, malware, and command-and-control infrastructure. Built for organizations that want more than basic filtering, this 4-year service term extends protection across the life of the appliance and helps maintain consistent security coverage without frequent renewal cycles. It is a practical fit for teams that need to harden branch or edge deployments while keeping policy enforcement centralized and predictable. For environments where DNS is a common attack path, this service helps close a gap that perimeter controls alone can miss. It supports a stronger security posture by adding visibility into one of the most frequently abused protocols on the network. The result is cleaner traffic, fewer risky connections, and a better chance of stopping threats early—before endpoints, users, or applications are affected.
