As an IT professional, I get asked a lot how securing recursive DNS proactively can protect an organization’s network. With high-profile security attacks occurring every day, organizations are more concerned than ever with cybersecurity with many going well beyond anti-virus protection and firewalls to adopt multiple layers of security such as intrusion prevention systems, sandboxing, and secure web gateways.
