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.
