Replacing Cisco Umbrella in 2026: Why DNS Filtering Stopped Being Enough

Cisco Umbrella did the job for a long time. It still does, for the right org. The problem is the org you're running in 2026 is not the org Umbrella was designed to protect. Distributed teams, AI tool sprawl, regulated data, and SaaS-tenant control all push past what DNS filtering and a backhauled SWG can do.

The two-sentence version: A Cisco Umbrella replacement in 2026 needs three things Umbrella was never built for: on-device SSL inspection, tenant-level Cloud Application Control for SaaS apps, and inline AI DLP for ChatGPT, Claude, and the long tail of agents. The migration is more straightforward than vendors make it sound, with most teams cutting over inside 90 days.

Why teams are looking to replace Cisco Umbrella

The complaints we hear from buyers cluster around four themes.

DNS-only filtering misses HTTPS content. Domain-level blocks are coarse. They don't see URL paths, file uploads, or prompt content. For a regulated team, "we blocked the domain" is no longer enough proof of control.

The SWG component still backhauls. Cisco's full SWG product routes traffic through Cisco data centers. That works for an office in Iowa. It does not work for a Singapore-based engineer or a partner team in Shanghai. Latency is real, and so is the privacy implication of routing user traffic through a vendor's cloud.

SaaS tenant control is missing. Most legacy DNS and SWG products can't tell the difference between corporate ChatGPT and personal ChatGPT. They live on the same domain. If your governance plan depends on blocking personal accounts while allowing the enterprise tenant, you need tenant-level control. DNS filtering can't do that.

Pricing and renewal lift. Buyers tell us Cisco renewals get bigger every cycle, and the surface area you actually need (DNS plus SWG plus CASB plus AI controls) ends up costing more than a unified platform that does all four.

What DNS filtering misses

This is the question that decides whether you actually need to replace Umbrella or just upgrade your tier. A short version of the answer:

• HTTPS payloads. DNS filtering ends at the domain name lookup. The body of the request is invisible.
• File uploads. A user uploading a customer list to a sanctioned SaaS domain is undetectable to DNS.
• Prompt content. The text pasted into ChatGPT or Claude is invisible to DNS.
• SaaS tenant identity. Personal vs. corporate accounts on the same domain look identical.
• MCP-connected agent activity. Most MCP servers run on legitimate cloud domains. DNS sees the domain, not the agent activity behind it.

If any of those gaps map to a real risk in your org, DNS-only is not the right control plane.

What a Cisco Umbrella replacement actually needs to do

Eight capabilities that should be on your evaluation grid:

1. On-device SSL inspection so HTTPS payloads are visible without a third-party data center in the loop.
2. URL-level filtering and category control across web traffic.
3. Cloud Application Control to allow enterprise SaaS tenants and block personal ones.
4. Inline DLP for files and prompts going to any AI tool.
5. CASB coverage for data at rest in OneDrive, Google Drive, and other cloud storage.
6. Shadow IT and shadow AI discovery in the same product.
7. One console, one agent, one billing line.
8. Architecture that works in China and other restricted regions where backhauled SWG fails.

If a vendor checks fewer than six of those, you are looking at another point product, not a real Umbrella replacement.

The Greylock story: a real Umbrella replacement

Greylock Partners is the iconic Silicon Valley VC firm behind LinkedIn, Discord, Figma, and Workday. They were on Cisco Umbrella. They moved to dope.security and went from first proposal to signed contract in 27 days.

The case against Umbrella was specific. DNS-only filtering missed HTTPS traffic, and the SWG component backhauled through Cisco's data centers, which added latency for a distributed, device-first VC team. Greylock deployed dope.security via Intune in a phased rollout and was up and running across the firm without an army of consultants. The team's own quote: "We are signed! We are excited to be working with you and the team. Thanks for always checking in and keeping this partnership warm. Let's go!"

Greylock isn't the only one. Another Cisco Umbrella customer migrated 2,000 machines to dope.security in two days. The migration lift is real but it's nothing like the deployment lift Cisco itself implies.

How dope.security compares to Cisco Umbrella

The high level differences:

Architecture. dope.security runs on-device. Traffic flies direct to the destination with no backhaul. Umbrella's SWG tier routes through Cisco data centers.

SaaS tenant control. Cloud Application Control is a first-class feature in dope.console. Umbrella requires layering additional Cisco products to approximate it.

AI governance. Three layers from one console: shadow AI discovery, SWG policy, and tenant control. Inline AI DLP through Dopamine DLP. Umbrella does not have a comparable AI control surface.

Geographic coverage. dope.security works in restricted regions like China where backhauled SWGs struggle. Umbrella's geo coverage depends on Cisco's data center map and the routing to it.

Deployment lift. Cisco Umbrella migration to dope.security: 2,000 machines in two days for one customer, 99% of devices in a week for Outreach Health, 27 days from first touch to signed contract for Greylock.

Console UX. dope.console was built from the ground up as a single console for SWG, CASB, DLP, and CAC. Cisco's stack is a series of consoles stitched together over time.

The bottom line

A Cisco Umbrella replacement in 2026 isn't a like-for-like swap. It's an upgrade from DNS-plus-cloud-proxy thinking to on-device SWG with tenant control and AI DLP in the same agent. The migration is doable inside a quarter. The renewal savings usually pay for the rest.
