DNS-Level Threat Filtering
Every website address a business device tries to reach is checked against a live threat list before the connection goes through, so phishing pages, malware hosts and attacker servers are blocked before your devices ever make contact with them.
What you're actually up against
Phishing & Social Engineering
Employees can be tricked into revealing passwords or sensitive information.
Ransomware
Attackers can encrypt business data and demand payment to restore access.
Weak Passwords
Compromised or reused passwords can provide attackers with access to business systems.
Unpatched Systems
Outdated software can contain vulnerabilities that attackers exploit.
Data Breaches
Sensitive customer, employee and business information can be exposed or stolen.
What happens without DNS-Level Threat Filtering
Most attacks don't arrive fully formed on a device. They rely on the device making contact with something on the internet first, whether that's fetching a malicious file, pulling up a fake login page designed to steal credentials, or quietly sending data back to whoever launched the attack.
Without a check at that address-lookup stage, a device can land on a convincing copycat site and start downloading harmful content before anything on the device itself raises a flag. And if an infection does take hold, malware that can communicate freely with its controller tends to cause considerably more damage than malware that can't reach out at all.
What you'll get once DNS-Level Threat Filtering is in place
- Every web address a device tries to reach checked against a live threat database at the moment of lookup, before any connection is established.
- Known malware sources, phishing pages and attacker command-and-control servers blocked before your device exchanges any data with them.
- Per-device protection that travels with the device, so remote workers and staff on the move get the same level of checking as anyone inside the office.
- A meaningful limit on what a hidden infection can do, since malware that cannot reach its controller is far more restricted in what it can carry out next.
- Visibility into what your devices are attempting to reach, which can surface risky browsing patterns or a quietly compromised machine before it becomes a larger problem.

DNS-Level Threat Filtering questions
They do different jobs. Antivirus largely looks at files already sitting on your device and flags what it recognises as harmful. DNS filtering works at an earlier point: it checks where the device is trying to go before the connection is even made. A phishing site, for example, might not trigger antivirus at all because no malicious file has landed yet. Running both gives you checks at two separate stages rather than relying on one.
Yes. The filtering runs on each device rather than at your office router, so it travels with the device. A laptop on a home broadband connection or a coffee shop network gets the same level of protection as one connected inside your office. That matters a lot when staff are working across multiple locations.
Sites flagged as hosting malware, running phishing campaigns, acting as remote-control points for attacker tools, or distributing harmful content. The threat list is updated continuously, so newly registered malicious domains are caught quickly rather than waiting for a scheduled update cycle.
In normal day-to-day use, no. The check happens in a fraction of a second at the lookup stage. Your staff will not notice any difference in how quickly sites load.
It can disrupt key parts of a ransomware attack. Many ransomware campaigns need to fetch tools or instructions from an external address, and some attempt to send stolen data outward before locking down your files. Blocking those outbound connections at the lookup stage can slow or limit an attack in progress. That said, no single security layer is a complete answer on its own. Combining DNS filtering with next-generation antivirus and a reliable backup gives your business considerably stronger overall resilience.
