SonicWall DNS Security Service for TZ580 1 Yr | DNS Protection, SMB

Stop DNS-driven attacks before they turn into incidents. SonicWall DNS Security Service for TZ580 adds a dedicated security layer that inspects and filters DNS activity to help block access to malicious domains, reduce exposure to phishing infrastructure, and interrupt command-and-control traffic. For teams running TZ580 appliances, it extends protection at the point where many threats first attempt to connect. This 1-year service is designed for organizations that want stronger threat control without adding operational complexity. It fits into existing SonicWall deployments and supports a more disciplined security posture by helping enforce DNS policy consistently across the environment. That matters when you need to protect users, preserve uptime, and reduce the chance that a single bad click becomes a broader compromise. Compared with basic DNS filtering, this service is built for security teams that need more than simple category blocking. It helps close a common blind spot in the attack chain and gives the TZ580 a more complete defensive profile. For environments where every layer must justify itself, DNS security is a practical upgrade with clear value.
