SonicWall DNS Filtering Service for TZ570P 6-Year | Security Subscription

Stop risky domain traffic before it becomes a security event with DNS filtering coverage for the SonicWall TZ570P. This 6-year service adds a policy-driven layer of protection at the DNS level, helping reduce exposure to phishing, malware, and other web-based threats without adding complexity to daily operations. For security teams, the value is straightforward: fewer dangerous requests reach the network, and acceptable-use policies are easier to enforce. DNS filtering is especially effective where you want broad coverage with minimal user friction, making it a strong fit for distributed environments, branch offices, and organizations that need consistent controls across many users. Compared with basic firewall-only approaches, DNS filtering gives you a more targeted way to shape internet access and reduce attack surface. With a long service term, procurement is simplified and security posture stays consistent over time, which is exactly what mature infrastructure teams expect from a paid security subscription.
