DNS is the Internet protocol that converts website names (called domain names) to IP addresses. Filters at that level prevents the DNS resolution for the blocked sites, so their content is never loaded. It is the fastest way to block sites.

Network Security

KA-WALL's security solution provide powerful, real-time protection that ensures service continuity, best performance and improved network control.

Internet Filter

Protect your network from malware, ransomware, malicious & viral websites, fake, fraudulent or scam websites, and phishing attacks with KA-WALL real time AI driven protection.

URL Filter

In addition to the automatic network content filter, you can add a URL to the blacklist to avoid access to specific websites from your network.

Block Websites

KA-WALL uses the best's antivirus cloud databases to identify and block known malicious sites, preventing infection even before you click. The protection is more precise than normal DNS-based filtering because it detects and blocks specific URLs rather than generic domain names.

Restrict Access to Adult Content

KA-WALL is a web filter that restricts the access of children and adolescents to undesirable sites, such as websites with porn content, propaganda of violence, drugs and crime.

24/7 Auto Update

KA-WALL stays in sync with the best's antivirus cloud databases to get the latest signatures for the Intrusion Prevention System, Malicious Site Blocking, Infected Device Detection and Blocking, and Content Filter features.

Network-wide Ad Blocking

Instead of browser plugins or other software on each device, KA-WALL in one place and your entire network is protected. Network-level blocking allows you to block ads in non-traditional places such as mobile apps and smart TVs, regardless of hardware or OS.

Real-time stats

Our Web interface offers control of your KA-WALL and a central place to view your network access statistics for all users. We also include an API for extending these stats.

Improve network performance

Since advertisements are blocked before they are downloaded, network performance is improved and will be faster and more secure and reliable.

Cyber Safety for Kids

Keep your kids safe when they explore the internet.

The online world is becoming every child’s favorite playground. With more children accessing the Internet with different devices, they are learning and growing more each day. When used appropriately the cyber world can be your child’s portal to achieve great things.

While every parent wants their child to have access to the latest and best information, they also know that safety is paramount.

Learning is not limited to children alone. It is important for parents to know what is out there. With the launch of new apps and social media sites, children are exposed to new things – things with the potential to destabilize them psychologically. As a parents it is best to stay fortified with all the information there is know about emerging threats, the latest school yard jargon and ways to deal with issues that emerge as a result of cyber behavior.

KA-WALL was designed to help you look out for your kids online and for their future.
