DNS Firewall stops malware and ransomware

CIRA's DNS Firewall provides protection against malware and phishing attacks by blocking access to malicious websites.

CIRA combines advanced data science with decades of experience managing the DNS to provide a critical element of your defence-in-depth strategy.

Strengthen your defence-in-depth strategy

Cybersecurity is a game of layers. No one cybersecurity solution is 100% effective. Whether you have traditional endpoint or firewall protection, a defence-in-depth strategy that includes a DNS firewall is essential.

DNS Firewall adds a cost-effective, low-maintenance layer to your cybersecurity footprint. By monitoring and analyzing your DNS traffic, DNS Firewall can block users from accessing malicious websites, prevent phishing attacks, and even stop malware already on your network from accessing the internet.
