Identify and stop internet-based threats where they begin—beyond your borders.

Stop threats before they reach your network. 

Internet-based attacks in the form of malware, phishing, and ransomware can happen at any time, and a successful attack can damage your reputation and bottom line. Operating from the cloud, DNS Safeguard acts as a DNS firewall by preventing your on- and off-network devices from connecting to malicious sites. It identifies where dangerous domains and other intrusive internet infrastructures are staged, then blocks those requests over any port or protocol. 

When it comes to DNS security, finding a partner you can trust is critical. Our Verizon Threat Research Advisory Center (VTRAC) analysts keep up with rapidly changing threats by processing more than 1 million security events every day at our global network operations centers and security operations centers. With Verizon, you can trust us to protect your network the same way we protect our own. 

What is DNS Safeguard?

DNS Safeguard is a cloud-based DNS security platform that blocks unsafe internet destinations at the earliest point of contact, before a connection is made. Protect your network from web content and sites known for malware, phishing, ransomware, and other common and uncommon threats. 

How does DNS Safeguard work?

DNS Safeguard reviews every DNS request, identifies where it came from, and either routes the traffic seamlessly to the appropriate location, or blocks it if it’s identified as malicious. In addition, VTRAC analysts provide continuous updates, integrating our threat feeds with intelligence from the Cisco Umbrella platform.

Features & benefits

Using the latest intelligence, DNS Safeguard identifies where dangerous domains and other intrusive infrastructures are staged. This prevents your devices—on or off your network—from connecting to malicious sites, allowing you to manage the internet experience with greater control. Other features and benefits include:
