SonicWall 02-SSC-5592 DNS Filtering Service for TZ570W 4-Year | Security

Extend DNS-layer protection on your SonicWall TZ570W with a 4-year DNS filtering service. By controlling domain resolution before a connection is made, this service helps reduce exposure to phishing, malware delivery, and unwanted web destinations while giving security teams a cleaner way to enforce acceptable-use policy. For small and midsize environments, DNS filtering is valuable because it adds protection without requiring a major redesign of the network. It works at a point where threats are easier to block and user impact is easier to manage. That makes it a strong fit for organizations that need consistent policy enforcement across offices, remote users, or mixed device environments. The 4-year term supports longer planning cycles and reduces the churn of short renewals. For teams standardizing on SonicWall security, this service helps keep the TZ570W aligned with a layered defense strategy that is easier to administer and more difficult for users to bypass. It is a focused control that improves security posture while keeping operations straightforward.
