For many organisations Cisco Umbrella has been worth it. DNS-layer security is quick to deploy and stops a large share of threats before a connection is ever made. In 2026, though, the answer depends heavily on timing, because Cisco has announced that Umbrella is being retired.
Where Umbrella delivers good value
- Fast deployment. Pointing your network’s DNS at Umbrella can protect a whole office in under an hour, with no hardware to install.
- Low latency. Anycast routing sends each query to the nearest Cisco data centre, so users rarely notice it.
- Protocol coverage. Because it works at the DNS layer, it protects every port and application that uses DNS, not only web browsers.
- Threat intelligence. Verdicts draw on Cisco Talos and Umbrella’s own global DNS data, which is especially good at spotting new malicious domains.
- Roaming protection. The Umbrella module in Cisco Secure Client keeps laptops protected off network.
Where it falls short
- DNS has limited visibility. It sees the domain a user visits but not the full URL, the page content or what they upload.
- Full inspection needs a higher package. URL filtering, TLS decryption, DLP and the cloud firewall are only available in the SIG packages.
- Decryption takes tuning. The secure web gateway needs the Cisco root certificate on every device and exceptions for apps that use certificate pinning.
- Limited insight into AI use. DNS can show that someone visited an AI chatbot, but not which data they pasted into it.
The 2026 factor: end of sale
| Milestone | Date |
|---|---|
| End of sale for Umbrella DNS and SIG | 31 January 2027 |
| Last date to renew or add subscriptions | 31 January 2028 |
| Last date of support | 31 January 2029 |
So, is it worth it for you?
| Your situation | Verdict |
|---|---|
| Existing customer, happy with DNS protection | Worth keeping for now, but start planning a migration before 2028. |
| New buyer | Buying a product with a set retirement date rarely makes sense. Compare Cisco Secure Access with other SSE and DNS security platforms instead. |
| Need to govern generative AI and Shadow AI | Umbrella alone will not be enough. Look at tools that inspect prompts and data on the endpoint. |
Umbrella remains a solid first line of defence. The question in 2026 is less whether it works and more whether you want to commit to it while its successor is already on the market.
