Sophos DNS Protection enforces security at the DNS layer - the lightest, highest-leverage control in the security stack. Block connections to malicious, phishing, and policy-violating domains before the browser, app, or malware ever opens a TCP connection. Roaming agent extends the same policy to off-network users.
Most malware needs DNS to resolve its command-and-control infrastructure. Most phishing relies on DNS to load the lure page. Block at DNS and you knock out the first step of most attack chains for almost no overhead.
Resolution requests for known-malicious domains never return an answer. Browsers, apps, and malware all hit a dead end before any TCP handshake, before any payload, before any inspection.
A lightweight agent on each endpoint forwards DNS to Sophos’s resolvers regardless of network. Users get the same blocking policy at home, at the coffee shop, on cellular - everywhere.
SophosLabs feeds updated continuously with the latest known-bad domains: malware C2, phishing kits, exfiltration endpoints, and active-attack infrastructure.
Block by content category in addition to threat intel. Adult, gambling, file-share, social media, streaming - whatever your acceptable-use policy says, enforce it at DNS.
Override category and intel rules for specific domains. Need to allow a borderline business app, or block a legitimate-looking site you don’t trust? Manage exceptions in Sophos Central.
See exactly which users, devices, and apps are querying which domains. Spot policy violations, sanctioned-but-noisy apps, and possible compromises that show up as outbound DNS anomalies.
A surprising amount of attack tooling depends on DNS at runtime. Block the resolution, you break the tooling. And it’s the only layer where you get this control without inspecting payloads, without decrypting traffic, and without any noticeable overhead.
DNS Protection is one of those products where the question is rarely “should we?” and usually “how fast can we?” These are the three deployments where the value shows up fastest.
Smaller organizations whose firewall doesn’t do URL category filtering or whose Wi-Fi guest network is wide open. DNS Protection adds web-filtering posture without a firewall upgrade.
Web filtering without a firewall changeYou have a firewall doing perimeter filtering, but half your users are at home or on the road. The roaming agent extends the same DNS policy off-network so policy travels with the user.
Same posture, any networkK-12 education, healthcare, public sector, and family-friendly organizations needing content-category enforcement. DNS Protection produces the audit trail those frameworks expect.
Audit-ready content filteringDNS Protection is the wide-net layer; pair it with the surgical layers around it for full coverage.
DNS Protection is included in the Workspace Protection bundle alongside Endpoint, Mobile, ZTNA, Protected Browser, and Email Monitoring - usually cheaper than buying separately.
DNS blocks the obvious bad. Protected Browser isolates the maybe-bad. Together they form a layered safe-browsing posture for users.
Sophos Firewall does deep packet inspection on traffic that does get through. DNS Protection catches the easy stuff before the firewall has to inspect it.
