Introducing Secure Access – DNS Defense


Cost-effective protection of your organization’s network and users is critical. That’s why I’m excited to announce the availability of Cisco Secure Access – DNS Defense, the newest member of the Secure Access product family.

Building upon Cisco’s position as the leading provider of DNS-layer security, we now offer a seamless pathway to our Universal ZTNA solution. Whether you’re a prospective customer looking to strengthen your network and user security, or an existing Cisco Umbrella DNS customer exploring what’s next, Secure Access – DNS Defense delivers value, simplicity, and unmatched protection.

With hybrid work, organizations need user protection on and off the corporate network. Many want to secure users and networks with a scalable foundation for zero trust security. Cisco Secure Access – DNS Defense delivers both with robust foundational security that is simple to deploy.

Cisco Secure Access – DNS Defense employs advanced AI-powered capabilities, such as DNS tunneling mitigation and Domain Generation Algorithm (DGA) detection, to stop sophisticated threats before they can take hold. These enhancements build upon Cisco’s top industry ranking in DNS-layer security, as recognized by GigaOM and Miercom, ensuring you’re protected from ransomware, phishing, and advanced threats.

Across 190+ countries, Cisco processes over 800 billion DNS requests daily, affording us unparalleled visibility into global threats. Secure Access – DNS Defense delivers faster, more precise threat detection with fewer false positives. This ensures threats are stopped at the DNS layer—before they can even reach your network and endpoints.

Unlike other Secure Service Edge (SSE) solutions that have added basic DNS security in a “checkbox” attempt to meet market demand, Cisco Secure Access – DNS Defense embeds strong security into its global network of 50+ DNS data centers. Among all SSE solutions, only Cisco’s features a recursive DNS architecture that ensures low-latency, fast DNS resolution, and seamless failover, delivering a superior user experience with stronger threat defense.

For organizations leveraging SaaS platforms like Microsoft 365, Google Workspace, and Box, Secure Access – DNS Defense (Advantage Package) includes SaaS API Data Loss Prevention (DLP) to discover and protect sensitive data stored and shared in your cloud-sanctioned applications. Further, it includes Cloud Malware Protection to identify and remove malware from cloud file storage applications, preventing malicious files from reaching endpoints. These features automatically protect sensitive data in cloud applications, helping you maintain compliance, and safeguard your intellectual property.

If you’re an existing Cisco Umbrella DNS customer, we’ve designed Secure Access – DNS Defense with you in mind. Our goal is to provide a simple upgrade path to our most modern platform, providing you with more value, protection, and capability — without extra cost.

Upgrading has never been easier. With our Upgrade Manager built into the Umbrella dashboard, upgrading to Secure Access – DNS Defense is simple. Your configurations are seamlessly transferred, and your existing policies are automatically converted to an easy to manage rules-based policy, ensuring zero disruption to your operations.

Secure Access – DNS Defense retains the features you’ve come to rely upon with Umbrella DNS while adding the powerful new capabilities of cloud malware scanning and SaaS API DLP—at no additional cost. Whether you choose DNS Defense exclusively or explore the broader possibilities of Cisco’s Secure Access product family, Secure Access adapts as your needs change.

Secure Access – DNS Defense can act as an onramp to Cisco’s Universal ZTNA vision. When you’re ready, you can easily add additional integrated SSE components—like Zero Trust Network Access (ZTNA) and Secure Internet Access (SIA) with full DLP, CASB, SWG, RBI and more—all within the same unified console, and at your own pace.

We’re honored to be the trusted DNS-layer security partner for over 40,000 customers worldwide. Secure Access – DNS Defense is designed to meet the needs of organizations of all sizes. For prospective customers, it’s the most cost-effective way to enhance your security posture, protect your hybrid workforce, and accelerate connectivity. For our valued Umbrella DNS customers, it’s a seamless, cost-neutral upgrade that delivers even greater value.
