Cisco Umbrella vs Palo Alto Prisma Access: A DNS Filter Against a Cloud Firewall
.jpeg)
Cisco Umbrella and Palo Alto Networks Prisma Access solve different-sized problems. Umbrella is DNS-layer security with an optional cloud proxy (SIG). Prisma Access is a cloud-delivered firewall and secure web gateway that extends PAN-OS policy to remote users and branches. Prisma Access is far deeper and far heavier. Moving from Umbrella to Prisma Access isn't a swap. It's a platform decision.
How do they compare?
| Cisco Umbrella | Prisma Access | |
|---|---|---|
| What it is | DNS filtering, plus SIG cloud proxy | Cloud-delivered firewall and SWG built on PAN-OS |
| Typical buyer | Teams that want simple web filtering | Enterprises standardized on Palo Alto firewalls |
| HTTPS inspection | SIG only | Yes, in Palo Alto's cloud |
| Endpoint client | Cisco Secure Client | GlobalProtect |
| Deployment lift | Low for DNS, moderate for SIG | High |
| Price position | Entry to mid | Premium |
| Analyst view | Cisco placed as a Challenger in Gartner's 2026 SASE Platforms Magic Quadrant | Palo Alto Networks a Leader in Gartner's SSE Magic Quadrant three years running, including 2025 |
| Product status | End of support January 31, 2029 | Actively developed |
Where does Cisco Umbrella fit?
Umbrella's appeal has always been simplicity. Point DNS at it and you're filtering domains across the whole network in an afternoon. For Cisco shops, it plugs into Duo, Meraki, and Cisco SD-WAN.
Two limits push teams to look elsewhere:
- DNS can't see inside HTTPS. No URL path, no upload, no account context.
- The end-of-life timeline. Cisco's bulletin EOL15975 sets the last renewal date at January 31, 2028. The path Cisco recommends is Cisco Secure Access.
Where does Prisma Access fit?
Prisma Access makes sense when you already run Palo Alto firewalls and want one security model from the data center to the remote laptop.
- Policy parity. The same rule logic you use on-prem, extended to the cloud.
- Depth. Firewall, SWG, and threat prevention in one service.
- Trade-offs. It's heavy to deploy and priced at the premium end. The value assumes you're committing to more of the Palo Alto platform, which is a bigger decision than replacing a DNS filter.
If your starting point is "our DNS filter is going away," Prisma Access is often more platform than the problem needs.
What do both have in common?
Both inspect traffic in the vendor's cloud. Every request takes a stopover, HTTPS is decrypted off the device, and users far from a point of presence feel it. Cloud proxies typically add 40 to 80 ms near a PoP and 150 to 400 ms far from one.
The lighter third option
dope.security puts the secure web gateway on the endpoint. No DNS ceiling, no cloud firewall project.
| Cisco Umbrella | Prisma Access | dope.security | |
|---|---|---|---|
| Sees inside HTTPS | SIG only | Yes | Yes |
| Where decryption happens | Cisco data center | Palo Alto cloud | On the device |
| Traffic detour | Yes with SIG | Yes | None |
| Time to deploy | Hours to weeks | Weeks to months | Agent through MDM, live on install |
| Policy push | Cloud-side | Cloud-side | Seconds |
| AI account control | Limited | Yes | Cloud Application Control |
| DLP | SIG only | Yes | Dopamine DLP, LLM-powered, no rules to write |
| Network firewall and ZTNA | No | Yes | No |
| Covers unmanaged devices | Yes, at the resolver | Yes, via network | No |
Why teams leaving Umbrella pick it:
- It deploys like Umbrella, not like a firewall. Install the agent and a base policy enforces immediately. Greylock Partners went from first proposal to signed contract in 27 days. Another Umbrella customer moved 2,000 machines in two days.
- It sees what DNS can't. On-device SSL inspection covers every web transaction, and data never leaves the device.
- One console. SWG, CASB Neural, SSPM, AI Analytics, and Dopamine DLP live together in dope.console, with one-click SSO and SIEM integration.
- AI governance in a few clicks. Enter your ChatGPT Enterprise workspace ID or Claude organization ID in Cloud Application Control and personal accounts are blocked. It's simple to operate without a dedicated team.
- Policy per group. Custom categories, per-group overrides, and customizable Block and Warn screens that coach users instead of just stopping them.
The honest limits: dope.security isn't a network firewall, has no built-in ZTNA today, and protects managed Mac and Windows devices only. If you need firewall policy for branches and data centers, that's Prisma Access territory.
Which should you pick?
- Pick Prisma Access if you run Palo Alto firewalls and want a single policy model everywhere.
- Pick Cisco Secure Access if you want to stay with Cisco.
- Pick dope.security if you need full web, SaaS, and AI security for a distributed workforce without a months-long project.

Frequently asked questions
Is Palo Alto a competitor to Cisco Umbrella?
Yes. Palo Alto Networks Prisma Access competes with Umbrella SIG as a cloud-delivered secure web gateway, with a much broader firewall feature set.
Is Prisma Access better than Cisco Umbrella?
It's deeper. It's also heavier and more expensive. It fits best when you already run Palo Alto firewalls.
Can Prisma Access replace Cisco Umbrella?
Yes, but it's a larger migration than moving between DNS filters, with new agents, policies, and network design.
Does Cisco Umbrella include a firewall?
Umbrella SIG includes a cloud-delivered firewall. The DNS packages don't.
What is a simpler alternative to both?
dope.security: an on-device secure web gateway with SSL inspection, Cloud Application Control, and Dopamine DLP, managed from one console.
