Cisco Umbrella vs Netskope: DNS Filtering Meets Cloud Proxy

Cisco Umbrella and Netskope solve different halves of the same problem, which is why teams keep ending up with both and a confusing bill. Umbrella started as DNS-layer filtering. Netskope started as a cloud proxy and CASB. If you are comparing them, you are really asking how much inspection you actually need and where it should happen.

Short answer: Cisco Umbrella filters at the DNS layer and is blind to URL paths and encrypted content unless you add its cloud proxy, while Netskope proxies traffic through its own network. dope.security inspects everything on the device and flies direct, replacing the DNS resolver, the proxy, and the second console with one agent.

DNS filtering versus full inspection

DNS filtering answers one question: should this domain resolve or not. That blocks known-bad domains and it is fast, but it cannot see the path after the domain, it cannot read TLS-encrypted content, and it cannot tell a corporate Google account from a personal one. To get URL filtering and SSL inspection, Cisco Umbrella points you at its Secure Internet Gateway, which is a cloud proxy that backhauls traffic. So you end up with the proxy model anyway.

Netskope skips the DNS-only stage and proxies from the start. It sees more than DNS, but everything still detours through Netskope's points of presence. Two roads, same toll booth.

Where each one leaves a gap

Umbrella's gap is depth. DNS is a coarse filter, and the moment you need URL paths, TLS content, in-app actions, or AI prompt inspection, you are buying the proxy and accepting the backhaul. Netskope's gap is the detour and the module sprawl. dope.security closes both: full inspection at the depth Netskope offers, on the device where Umbrella wishes it could see, with no second console.

Deployment is where this gets decided

Greylock Partners left Cisco Umbrella for dope.security and signed in 27 days, in part because Umbrella's DNS-only filtering missed HTTPS traffic and the proxy still backhauled through Cisco data centers. A separate Umbrella customer migrated 2,000 machines in two days. Cloud proxy rollouts and DNS-plus-proxy stacks rarely move that fast.

Is Cisco Umbrella or Netskope better?

If you only want to block bad domains cheaply, Umbrella's DNS tier is simple. If you need full content inspection, Netskope does more out of the box but routes everything through its cloud. Neither inspects on the device, which is the choice that removes latency and keeps data local.

What replaces both Cisco Umbrella and Netskope?

dope.security replaces the DNS resolver and the cloud proxy with a single agent that inspects on the endpoint and flies direct. You get SWG, CASB Neural, Dopamine DLP, and three-layer AI governance under one console. Read what Cisco Umbrella is and is not, see the case for going beyond DNS filtering, then start a free trial.
