DNS Firewall for Small Business: Affordable Protection That Works
By [FILL IN], [FILL IN] · Last updated
Small businesses are prime phishing targets. See how a DNS firewall protects every office device without IT staff or expensive hardware.
Why small businesses are targeted
Attackers know small offices rarely have dedicated security staff. One clicked phishing link can lead to stolen banking credentials, ransomware or invoice fraud.
What a DNS firewall adds
A single change on the office router puts every laptop, phone, printer and guest device behind the same protection.
- Blocks phishing links even when an email filter misses them
- Stops ransomware from reaching its command servers
- Prevents staff from landing on fake login pages
- Shows which devices contact suspicious domains
Cost versus impact
A DNS firewall costs a fraction of an endpoint security suite and needs no hardware. It works alongside the antivirus and backups you already have.
A practical rollout
Start with security categories only, watch the log for a week, then add productivity rules such as blocking gambling or streaming during work hours.
