DNS (Domain Name System) filtering, also known as web filtering, is a security measure that helps protect your business from accessing harmful or inappropriate websites. Here's a breakdown of what it is and why it's essential for your business:

What is DNS/Web Filtering?
DNS filtering works by controlling which websites can be accessed from your network. When a user tries to visit a website, a DNS query is sent to a DNS resolver. If the resolver uses DNS filtering, it checks the requested domain against a blocklist or allowlist before resolving the query. If the domain is on the blocklist, access is denied¹².

Why Does Your Business Need It?

• Enhanced Security: DNS filtering blocks access to malicious websites that could host malware, phishing scams, or other cyber threats. This helps prevent data breaches and cyberattacks.
• Productivity Control: By restricting access to non-work-related sites, such as social media or gaming sites, you can help ensure employees stay focused on their tasks.
• Compliance: Many industries have regulations requiring businesses to protect sensitive information. DNS filtering helps meet these compliance requirements by preventing access to risky sites.
• Cost Savings: Preventing cyberattacks, and data breaches can save your business significant costs associated with recovery and downtime.

Implementing DNS filtering is a proactive step towards securing your business's digital environment. If you have any more questions or need further details, feel free to ask!
