Meet today’s work-from-home security challenges with DNS Filtering

Today, as more employees work from home, your network is more vulnerable than ever before to malicious websites. That’s why it’s crucial to include DNS Filtering in your organization’s security system.

Without DNS Filtering

Employees can accidentally access sites that trigger malware to be installed, or they can fall prey to a phishing scheme that uses a fictitious site to access secured information.

With DNS Filtering

IT teams can easily manage and alter their organization’s web filter, providing protection against malware and phishing campaigns across all networks and environments.

Define Unwanted Sites with Perimeter 81 DNS Filtering

Using the Perimeter 81 DNS filtering dashboard, your IT team can easily determine which IP sites and content will be blocked on their employee’s devices. Blacklisting, whitelisting and category-based groups can be used in combination, allowing you to fine-tune your DNS security policy. 

Define Unwanted Sites with Perimeter 81 DNS Filtering

Category-Based Filtering

Block access to the most popular and often compromised websites by category, such as social media and gaming sites.

Blacklisting

Add specific, non-category-based websites you want to block through the blacklisting feature for added control.

Whitelisting

Give your IT team more control over the list of destinations that employees are allowed to access with the whitelisting tool. Ensure that the websites employees need for their job is accessible.

Once DNS Filtering is activated, it prevents your system’s DNS Resolver from identifying, retrieving, and displaying unwanted websites according to your definitions. Instead, Perimeter 81 displays an alert to the user that the URL or content they were trying to access is blocked.
