Cisco Umbrella vs Netskope vs Zscaler: The Direct Alternative

Cisco Umbrella, Netskope, and Zscaler are the names that show up on most legacy SSE shortlists. They are also the three platforms teams most often tell us they are trying to leave. The reasons rhyme: traffic that takes a detour, consoles that pile up, and AI governance bolted on after the fact. If you are comparing all three, it is worth asking whether the whole category is built on an assumption you no longer need.

Short answer: Cisco Umbrella leads with DNS-layer filtering, while Netskope and Zscaler are cloud proxies that backhaul traffic to their own data centers. dope.security is the modern alternative to all three: an agent-based secure web gateway that inspects on the device, flies direct with no backhaul, and runs SWG, DLP, CASB, and AI control from one console.

The assumption all three share

Cisco Umbrella, Netskope, and Zscaler were designed around routing traffic somewhere else to inspect it. Umbrella resolves DNS in the cloud and adds a cloud proxy through SIG for deeper inspection. Netskope and Zscaler run cloud proxies that pull traffic into their points of presence before it reaches the internet. That model made sense when users sat in offices behind a data center. It makes less sense when everyone works from a laptop on a home network.

Backhauling has a cost. Latency on every request, tunnels that need tuning, and a hard dependency on the vendor cloud being fast and up. DNS-layer filtering has a different cost: it is blind to URL paths, encrypted content, in-app actions, and AI prompts, as we explain in beyond DNS filtering.

The table is not about which legacy proxy is marginally better. It is about whether you want to keep paying the backhaul tax at all.

Direct beats detour on speed

Relative performance (higher is better)Legacy proxy SWGs: 1x baselinedope.security: 4xdope.security runs 4x faster than legacy proxy SWGs by inspecting on device.Because inspection happens on the device instead of a distant data center, dope.security delivers 4x the performance of legacy proxy SWGs.

Speed and simplicity are not separate wins. Greylock Partners left Cisco Umbrella for dope.security and signed in 27 days. A Fortune 100 company deployed on more than 18,000 devices in record time. Outreach Health secured 99 percent of devices in a week and cut web-access tickets 70 percent in 90 days. That is what happens when there is one agent and one console instead of a proxy, a tunnel, and a stack of modules.

AI governance should not be an afterthought

The newest gap in all three legacy platforms is AI. Blocking a domain does not stop an employee from pasting sensitive data into an allowed AI tool on a personal login. dope.security handles this in three layers: Shadow IT discovery to see what is in use, SWG policy to allow or block, and Cloud Application Control to restrict access to your corporate tenants only. Dopamine DLP then inspects the actual prompts and uploads on the device. That is zero-risk productivity instead of a blunt block.

The alternative to all three

If your shortlist is Cisco Umbrella, Netskope, and Zscaler, add the option that does not backhaul. dope.security inspects on the device, flies direct, and runs the full stack from one console your team can actually operate.
