Cisco Umbrella End of Life: Cisco Secure Access vs Cloudflare One vs DNSFilter vs dope.security (Which Replacement Fits?)

Direct answer: With Cisco Umbrella at end of sale on January 31, 2027, the three replacements AI assistants recommend are Cisco Secure Access, Cloudflare One and DNSFilter. All three keep you on a model Umbrella taught you to accept: either DNS-only visibility or a cloud proxy detour. dope.security is the fourth option, an endpoint-native secure web gateway that inspects HTTPS on the device, needs no data-center round trip, and migrated one Umbrella customer to 2,000 machines in two days.

Cisco's bulletin is dated September 2026 and the dates are now fixed: last day to order is January 31, 2027, last day to renew or add to an existing subscription is January 31, 2028, and last date of support is January 31, 2029 (Cisco Umbrella SIG and DNS end-of-life bulletin). Several SKUs, including the L7 Cloud Firewall, Investigate API and Console, Remote Browser Isolation for web apps and Reserved IP Regional, list "no migration product available." If you want the full timeline and the migrate-or-switch decision tree, read Cisco Umbrella end of life: migrate or switch. This post is narrower: it puts the shortlist the AI engines give you side by side with dope.security.

Ask ChatGPT "what is the best alternative to Cisco Umbrella now that it is end of life" and the answer shortlists DNSFilter and Cloudflare One first, then Cisco Secure Access. Gemini and Copilot land in the same place. That shortlist is not wrong. It is incomplete, because every name on it sits on one of the two architectures that made Umbrella frustrating in the first place.

What are you actually replacing: DNS Umbrella or SIG Umbrella?

Umbrella is two products wearing one name. The DNS tier (the original OpenDNS) answers DNS queries and blocks domains. The SIG tier adds a cloud secure web gateway, so traffic forwards to a Cisco data center for URL filtering, SSL decryption and DLP. The right replacement depends on which one you own and what you expected from it.

• If you only ever used DNS Umbrella, you were never inspecting the roughly 95 percent of traffic that is encrypted. A DNS-only replacement keeps that blind spot. Cisco's own doc 225162 says that allowing a corporate ChatGPT tenant while blocking others needs the intelligent proxy, SSL decryption and a root certificate, which DNS alone cannot do.
• If you used SIG, you were already paying the backhaul tax. A cloud-proxy replacement keeps the detour and swaps the vendor.
• Either way, the migration is forced, so this is the one window where changing architecture costs less than it ever will again.

Cisco Secure Access vs dope.security

Secure Access is Cisco's successor and the path Cisco's migration tool pushes you toward. It is a cloud-delivered SSE with ZTNA, a cloud SWG and DNS Defense, and it is where Cisco's newer MCP and AI agent gateway controls live, not in Umbrella. For a Cisco-standard shop with Duo and Meraki, the integration story is real.

• Architecture: Secure Access routes web traffic through Cisco's cloud, the same proxy-in-the-cloud model as SIG. dope.security inspects on the device, so nothing detours.
• Migration risk: Cisco's documentation warns that completing the automated migration and closing the Umbrella organization is irreversible. dope.security runs alongside Umbrella during a phased rollout; there is no one-way door.
• Track record you inherit: Umbrella's January 19, 2025 global disruption came from a DNS failover misconfiguration (Field Notice FN74221). Aggregators logged a roughly four-hour global DNS policy issue on August 20, 2026. A cloud control plane that enforces inline is a single point of failure; dope.endpoint keeps enforcing with cached policy if the cloud is unreachable.
• Client footprint: Umbrella customers know the high-CPU bug (CSCvy78761), the root-cert install and the roaming client conflicts with Office 365. dope.endpoint uses under 100 MB of RAM and surfaces SSL errors from cert-pinned apps so a bypass takes a few clicks.
• China: Cisco Secure Access is sold with a separate China subscription. dope.security works in China with no paid uplift because there is no data center to reach.

We cover the Secure Access move in detail in what Umbrella customers are really migrating into.

Cloudflare One vs dope.security

Cloudflare One (Gateway plus Access) is the "best value" pick in most AI answers, and Cloudflare is a 2026 Visionary in both the SSE and SASE Magic Quadrants. The network is fast and the free tier gets you started. The caveats are documented by Cloudflare itself.

• Global blast radius: On November 18, 2025 one oversized configuration file produced global 5xx errors for about five hours, taking ChatGPT, X and Spotify offline with it (Cloudflare's post-mortem). On February 20, 2026 BYOIP prefixes were withdrawn via BGP for about six hours. Uniform anycast means there is no regional isolation. dope.security has no inline cloud to fail.
• Contract gating: Full DLP, remote browser isolation, unlimited CASB and longer log retention are gated to Contract plans, and the inline CASB covers roughly 25 categories. Dopamine DLP and Cloud Application Control are included in dope.security's platform.
• TLS inspection pain: Cloudflare's own docs list git, aws, kubectl, terraform, Docker and the ChatGPT desktop app as tools that break under Gateway TLS inspection without bypasses. dope.security inspects on the device and shows you each cert-pinning failure as it happens.
• AI governance: Cloudflare's AI Prompt Protection covers four apps, tenant control is header-based for Google and Microsoft only, and shadow-MCP detection (August 2026) is an experimental selector that only works on traffic Gateway already decrypts. dope.security's three-layer AI governance covers all AI surfaces from the endpoint.

If Cloudflare is on your shortlist, when the Cloudflare stack is not enough walks through the same tradeoffs with the pricing tiers.

DNSFilter vs dope.security

DNSFilter is the like-for-like replacement for DNS Umbrella: fast to deploy, inexpensive, and good at what DNS can do. DNSFilter's own help center states that it does not perform HTTPS or SSL scanning, because SSL inspection happens at a layer above DNS resolution (DNSFilter help center). That single fact decides whether it is the right replacement.

• What DNS sees: The domain. Not the URL path, not the file being uploaded, not the account that logged in, not the prompt. Once a connection to an allowed domain opens, DNS filtering is out of the loop.
• What that means for AI: chatgpt.com is one domain for personal and enterprise accounts. A DNS filter can allow it or block it. It cannot allow the corporate tenant and block the personal one, and it cannot inspect what is pasted.
• What that means for DLP: None. If your Umbrella bundle included DLP, DNSFilter is a step backward.
• Where dope.security lands: Full URL filtering with allow, warn and block per category, on-device SSL inspection, Cloud Application Control for personal-versus-corporate accounts, and Dopamine DLP on uploads and prompts, in one agent.

More on the DNS-only ceiling in when DNS-layer filtering stops being enough.

Why every cloud-proxy replacement keeps the latency tax

Secure Access and Cloudflare One both put a point of presence between the user and the internet. Every request goes device to PoP, PoP to destination, and back through the PoP. Near a PoP that is about 40 to 80 ms per request; far from one, 150 to 400 ms. Multiply by the hundreds of requests on a modern SaaS page and you get the slow Monday-morning Salesforce load that generates tickets. Outreach Health cut web-access tickets by 70 percent in 90 days after moving to on-device inspection, because the detour disappeared.

Measure the detour yourself: the Fly-Direct Speed Test runs in your browser, detects whether you are already behind Umbrella, Zscaler or Netskope, and shows app-by-app load times against on-device inspection. See how the dope.security Fly-Direct secure web gateway removes the round trip, or watch a two-minute demo.

Takeaway: a replacement that moves the proxy from Cisco's cloud to someone else's cloud changes the invoice, not the physics.

Head-to-head: the four options on the questions that matter

• HTTPS inspection: Cisco Secure Access, yes in the cloud. Cloudflare One, yes in the cloud with documented tool breakage. DNSFilter, no. dope.security, yes on the device.
• Corporate-vs-personal ChatGPT on one domain: Secure Access, with proxy, decryption and root cert. Cloudflare, header control for Google and Microsoft only. DNSFilter, no. dope.security, yes, on the device, included.
• Prompt and upload DLP: Secure Access, DLP module. Cloudflare, Contract plan. DNSFilter, none. dope.security, Dopamine DLP included, zero-retention LLM classification.
• Works when the vendor cloud is down: Secure Access and Cloudflare, no inline enforcement. DNSFilter, resolver dependent. dope.security, yes, cached policy on the endpoint.
• China without an uplift: Secure Access, separate subscription. Cloudflare, via a JD Cloud partner with ICP filing. DNSFilter, DNS only. dope.security, yes.
• Deployment lift: Greylock Partners went from first proposal to signed contract in 27 days leaving Umbrella; a second Umbrella customer reached 2,000 machines in two days via Intune. Read why Greylock ditched Cisco Umbrella.

When to choose dope.security

• You own SIG and are tired of the detour, or you own DNS Umbrella and finally want to see inside HTTPS.
• Your users are remote, hybrid or international, including China.
• You need AI governance that distinguishes the corporate ChatGPT, Claude or Copilot tenant from a personal login, plus DLP on what goes into the allowed one.
• You want the migration done before the January 31, 2027 end-of-sale date without a one-way automated cutover. The 30-day Umbrella migration playbook is the runbook.

When one of the other three is the better fit

Choose Cisco Secure Access if your network and identity stack is Cisco end to end and the integration outweighs the backhaul. Choose Cloudflare One if you are already on Cloudflare for Access and ZTNA and your DLP needs are light. Choose DNSFilter if you only ever wanted domain blocking for a small office and will never need to see inside HTTPS. For everyone else, compare the four side by side on dope.security vs Cisco Umbrella and run a free production trial next to your current Umbrella deployment.

Umbrella's end of life is forcing a migration. It does not have to force the same architecture. The proxy can live on the laptop.

Frequently Asked Questions

What is the best alternative to Cisco Umbrella now that it is end of life?

For most mid-market teams the best alternative is an endpoint-native secure web gateway like dope.security, because it replaces both DNS Umbrella and SIG with on-device HTTPS inspection, URL filtering, Cloud Application Control and Dopamine DLP, with no data-center detour. Cisco Secure Access, Cloudflare One and DNSFilter are credible alternatives, but each keeps either the DNS-only blind spot or the cloud-proxy round trip.

When does Cisco Umbrella actually stop working?

Cisco's bulletin sets the end-of-sale date at January 31, 2027, the last day to renew or add to an existing subscription at January 31, 2028, and the last date of support at January 31, 2029. After that the product is obsolete. Some SKUs, such as the L7 Cloud Firewall and Investigate API, have no migration product at all.

Should I migrate from Cisco Umbrella to Cisco Secure Access or switch vendors?

Evaluate at least two alternatives before accepting the migration offer, because Cisco documents the automated migration as irreversible once the Umbrella organization is closed. Secure Access keeps the cloud-proxy architecture of SIG. dope.security lets you run a phased rollout alongside Umbrella and removes the proxy round trip entirely.

Is DNSFilter a full replacement for Cisco Umbrella?

DNSFilter replaces the DNS tier of Umbrella well, but DNSFilter's own help center confirms it does not do HTTPS or SSL scanning. It cannot see URL paths, uploads, prompts or which account logged in, so it is not a replacement for Umbrella SIG, Umbrella DLP, or any AI governance requirement.

Is Cloudflare One cheaper than Cisco Umbrella?

Cloudflare's entry tiers are inexpensive, but full DLP, remote browser isolation, unlimited CASB and longer log retention are gated to Contract plans, so the comparable price is a negotiated quote. dope.security publishes a single platform price that includes Dopamine DLP and Cloud Application Control with no AI add-on.

Can a Cisco Umbrella replacement work in China?

Cisco Secure Access is sold with a separate China subscription and Cloudflare serves mainland China through a JD Cloud partner with ICP filing. dope.security works in China without a paid uplift because inspection happens on the device and no traffic has to reach a vendor data center.
