DNS SECURITY

DNS service and cybersecurity

Cisco SD-WAN and Cisco Umbrella integration allows organisations to deploy DNS-layer protection across their network and extend security to hundreds of devices quickly and efficiently.

By inspecting DNS requests in real time, threats such as malware, ransomware and command-and-control (C2) callbacks can be blocked before a connection is established.

Strengthen DNS security across your network

Protect users, devices and locations with DNS security services designed to monitor and control DNS activity. Zen supports the management of primary and secondary DNS servers while applying cloud-delivered security policies to prevent access to malicious domains.

How DNS security works

DNS security protects your organisation by analysing DNS requests before a connection to a website or service is made.

1. A user or device requests a domain

When someone in your organisation tries to access a website or cloud service, their device sends a DNS query to resolve the domain name.

2. The DNS request is inspected

The request is analysed against threat intelligence and security policies to determine whether the domain is trusted or potentially malicious.

3. Threats are blocked early

If the domain is associated with malware, phishing, ransomware or command-and-control infrastructure, the request is blocked before any connection is established.

4. Safe requests continue normally

Legitimate requests are resolved as usual, allowing users to access the internet and cloud services without disruption.
