DNS Firewall
Protect your entire network at the DNS level — block malicious domains, phishing attacks, and malware before they reach your devices. Our DNS firewall solution, powered by NanoFirewall, provides a critical first line of defense without requiring software on individual endpoints.
In partnership with AST
NanoFirewall is developed by Advanced Security Technologies (AST). As an official partner, we deploy and manage NanoFirewall solutions for our clients.
NanoFirewall Features
DNS-Level Threat Blocking
Malicious domains are blocked at the DNS resolution stage, preventing connections to known dangerous sites before any content is loaded.
Zero-Latency Protection
DNS filtering operates at the network level with negligible impact on browsing speed — security without sacrificing performance.
No Client Installation Required
Protection is applied at the network level. No additional software needs to be installed on individual devices — simplifying deployment and management.
Phishing & Social Engineering Defense
Automatically blocks access to phishing websites and social engineering traps, protecting employees from credential theft and fraud.
Malware Domain Filtering
Continuously updated threat intelligence blocks connections to command-and-control servers, malware distribution sites, and botnet infrastructure.

Control access to website categories across your network — enforce acceptable use policies and reduce exposure to risky or unproductive content.
Reporting & Analytics
Detailed dashboards and reports on DNS queries, blocked threats, and network activity patterns to help you understand your security posture.
Compliance Support
Meet regulatory requirements with DNS-level logging, audit trails, and configurable policies that help demonstrate security compliance.
Easy Integration

Frequently Asked Questions
What is a DNS firewall and how is it different from a traditional firewall?
A traditional firewall inspects network packets and controls traffic based on IP addresses and ports. A DNS firewall works at the domain name resolution level — it blocks access to malicious websites by preventing your devices from resolving dangerous domain names. Both complement each other for layered security.
Does DNS firewall slow down internet speed?
No. DNS resolution happens in milliseconds, and filtering adds negligible overhead. In many cases, DNS firewall can actually improve performance by preventing connections to slow or resource-heavy malicious sites.
Can I customize which domains are blocked?
Yes. NanoFirewall supports custom allow and block lists, category-based filtering, and policy-based rules. You can tailor the protection to match your organization's specific needs and compliance requirements.
