Block phishing and malware on your office Wi‑Fi

Most small-business break-ins start with one click on a fake login page. A filter on your network stops that page from loading at all.

Short answer

Point your office router's DNS at Sheepdog Filter. Known phishing, malware and scam sites stop loading on every computer and phone on the network, with new ones added every hour. It takes ten minutes and needs no software on any computer.

What it stops

  • Phishing pages: fake Microsoft 365, bank, shipping and payroll logins.
  • Malware sites: pages that push fake updates, viruses and ransomware.
  • Scams: fake stores, tech-support scams and crypto scams.

Lists come from respected community sources and are refreshed every few hours, and newly seen sites are checked every hour.

Set it up

Create your account, then follow the guest Wi‑Fi guide on your office router. Put your team's devices on the Staff setting: adult sites, scams and malware blocked, everything else open. Guest and waiting-room Wi‑Fi uses Guest Wi‑Fi rules.

What it doesn't replace

A DNS filter is one layer. Keep computers updated, use two-step sign-in on email, and back up your files. Together they cover most of what goes wrong in a small office.

Do we need to install anything on our computers?

No. It works on the router, so every device on the network is covered.
