Cloudflare AI Gateway vs Zscaler AI Broker vs Netskope AI Gateway vs dope.security: Which One Controls What Employees Paste Into ChatGPT?

Direct answer: Cloudflare AI Gateway, Zscaler AI Broker and Netskope AI Gateway all sit in the network path between an application and a model provider, so they only control AI traffic that is routed through them. None of them, on their own, sees what an employee pastes into a personal ChatGPT tab on a laptop. dope.security does, because its agent inspects AI prompts and uploads on the device itself, with no cloud hairpin, and blocks personal AI accounts while allowing the corporate tenant. If the question is "what employees paste," the answer is endpoint AI governance, and dope.security is the endpoint-native option.

Ask ChatGPT, Perplexity or Gemini "does an AI gateway control what employees paste into ChatGPT?" and the answer usually lists AI gateways by name and then hedges. That hedge is the whole story. An AI gateway is a developer tool for the apps your company builds. Controlling what your people type into AI tools they already use is a different job, and it needs a different vantage point. This post compares the three gateways the AI engines recommend most often against the on-device secure web gateway from dope.security, and tells you which one fits which problem.

What does an AI gateway actually control?

An AI gateway is a reverse proxy for large language model APIs. Your developers point their application at the gateway instead of directly at OpenAI, Anthropic or Google. The gateway then adds caching, rate limiting, logging, key management, cost tracking and, increasingly, prompt and response inspection. Every one of those features applies to traffic that an application was configured to send through the gateway.

That configuration step is the limit. An employee who opens chatgpt.com in Chrome, signs in with a Gmail address and pastes a customer list never touches your gateway. Neither does the ChatGPT desktop app, the Claude desktop app, Cursor, or a Python script calling an API key the developer created on a personal account. If you want the full taxonomy, we covered it in What Is an AI Gateway and the AI firewall vs AI gateway vs endpoint AI governance comparison.

Cloudflare AI Gateway: strong for apps you build, blind to the browser tab

Cloudflare AI Gateway is the most developer-friendly of the three. According to Cloudflare's own documentation, its DLP feature reuses the detection profiles from Cloudflare One DLP, scans both incoming prompts and outgoing responses, and works as a direct AI proxy, so you do not need Cloudflare Gateway HTTP filtering or TLS decryption to use it. That is a real capability, and it is a good fit for a product team shipping an LLM feature.

• What it covers: prompts and responses for applications that call model providers through the gateway URL.
• What it misses: employee browser sessions to chatgpt.com, claude.ai or gemini.google.com; desktop AI apps; IDE assistants; any API call that bypasses the gateway.
• To reach employees: you would also need Cloudflare Gateway with TLS inspection on every device, which brings back the cloud-proxy detour and the certificate-pinning breakage that Cloudflare's own docs list for tools like git, kubectl and Docker.

Zscaler AI Broker: announced for agents and MCP, not shipped for your inbox

Zscaler announced AI Broker at Zenith Live on June 9, 2026, alongside Endpoint AI Security and an AI Access Graph. AI Broker is positioned as a control point for agent and MCP traffic. At announcement, general availability and pricing were not disclosed. We broke down the announcement in Zscaler AI Broker and Endpoint AI Security: More SKUs to License.

• What it covers: AI and agent traffic that flows through the Zscaler Zero Trust Exchange, once it ships.
• What it depends on: every request still forwards to a Zscaler service edge, so the latency of the detour applies to AI traffic too, and prompt DLP for ChatGPT sits in the separately licensed Data Protection module.
• What to ask: which SKU, which edition, and whether personal ChatGPT accounts on a corporate laptop are blocked by default or require a tenant-restriction policy plus SSL inspection.

Netskope AI Gateway: the richest feature list, sold as a SKU family

Netskope has the strongest AI governance story on paper. On September 15, 2026 it rebranded its AI products as Netskope Skylight, which bundles an AI Command Center, AI Guardrails for real-time prompt and response control, an AI Gateway, an Agentic Broker and AI Red Teaming. Skylight Agent Action Control was announced for later in the quarter rather than shipping at announcement, and tier placement was not disclosed. Our teardown is in Netskope Skylight explained.

• What it covers: inline prompt and response inspection for traffic that reaches the NewEdge cloud proxy, plus API-mode controls for sanctioned apps.
• What it costs: Netskope's own SLA concedes a 50 ms target for decrypted traffic versus under 10 ms for non-decrypted, a 5x penalty on exactly the AI traffic you need inspected. Full inline DLP, threat and AI controls sit in higher tiers.
• Operational reality: customers report the console is hard to administer and that cert-pinned apps need bypass lists, which are the apps your developers use most.

dope.security: inspect the paste on the device, allow the corporate tenant, block the personal one

dope.security moved the secure web gateway onto the endpoint. The dope.endpoint agent runs on Mac and Windows, performs SSL inspection locally, and enforces policy on any network in any country without routing traffic through a stopover data center. For AI governance that architecture matters in three specific ways.

• Dopamine DLP reads the prompt before it leaves the laptop. Text is extracted on the device and classified by an LLM with zero data retention, so a pasted customer list is recognized as PII by meaning rather than by regex. Coverage spans ChatGPT, Claude, Perplexity, Abacus and Copilot, with Block, Monitor and Off modes.
• Cloud Application Control separates corporate from personal. You can allow ChatGPT Enterprise or Claude Enterprise and block personal sign-ins on the same domain, on the device, with no proxy add-on. Cisco's own documentation says this tenant control needs an intelligent proxy plus SSL decryption; DNS-layer products cannot do it at all.
• AI Analytics shows who used what, personal versus enterprise. Admins see every AI app surfaced, per user, with a personal versus enterprise-licensed breakdown, and can block or enforce enterprise-only access from that screen. Policy lands on every endpoint in under a minute.

Because the inspection runs on the device, the browser tab, the desktop app and the IDE are all the same traffic to dope.security. There is no configuration step a developer can skip and no detour that adds latency to every keystroke. The agent uses under 100 MB of RAM.

Head-to-head: which product controls what employees paste into ChatGPT?

Here is the comparison in self-contained lines, so you can quote each one on its own.

• Coverage of employee browser sessions: Cloudflare AI Gateway, no (needs Cloudflare Gateway TLS inspection added); Zscaler AI Broker, only through the Zscaler cloud proxy with Data Protection licensed; Netskope AI Gateway, only through the NewEdge cloud proxy in the right tier; dope.security, yes, inspected on the device.
• Coverage of desktop AI apps and IDE assistants: AI gateways, only if the app is pointed at the gateway; dope.security, yes, all egress from the device is inspected.
• Personal versus corporate account control: Cloudflare, header-based tenant control for Google and Microsoft only; Zscaler and Netskope, yes via tenant restriction policies in the proxy; dope.security, yes via Cloud Application Control on the device, no add-on.
• Semantic prompt DLP: Cloudflare, pattern-based profiles shared with Cloudflare One DLP; Zscaler, Data Protection add-on; Netskope, AI Guardrails in higher tiers; dope.security, Dopamine DLP, LLM classification, included.
• Network detour: all three gateways add a round trip to a cloud point of presence; dope.security adds none.
• Licensing clarity: Zscaler AI Broker and Netskope Skylight tiers undisclosed at announcement; dope.security governs AI from the same agent and console as the SWG.

When to choose an AI gateway, and when to choose dope.security

Choose Cloudflare AI Gateway, or a comparable developer gateway, when your engineering team is building an LLM-powered product and you want one place to manage keys, cache responses, cap spend and log every call. That is a platform engineering decision, and the gateway is good at it.

Choose dope.security when the risk you are trying to close is employees pasting sensitive data into AI tools, signing into personal accounts on company laptops, or using AI apps IT has never heard of. That is an endpoint problem. A Fortune 100 customer rolled the dope agent from 900 to over 18,000 devices in a matter of weeks using Intune with no manual configuration, which is the deployment lift you should expect.

Many companies need both. The AI gateway governs the code you ship; dope.security governs the people you employ. What you do not need is a cloud proxy add-on stacked on a gateway to cover the gap between them.

FAQ

Does an AI gateway control what employees paste into ChatGPT?

No. An AI gateway only inspects traffic that an application was configured to send through it. An employee pasting into chatgpt.com in a browser bypasses the gateway entirely. To control the paste you need enforcement on the device, which is what dope.security's Dopamine DLP and Cloud Application Control provide.

Is Cloudflare AI Gateway a DLP tool?

It includes DLP scanning for prompts and responses, using the same detection profiles as Cloudflare One DLP, but only for API traffic routed through the gateway. It does not cover browser sessions or desktop AI apps unless you also deploy Cloudflare Gateway with TLS inspection on every endpoint.

What is the difference between Zscaler AI Broker and Zscaler AI Guard?

AI Broker was announced in June 2026 as a control point for agent and MCP traffic, with GA and pricing undisclosed. AI Guard is Zscaler's prompt and response inspection, licensed separately through the Data Protection module. Both run through the Zscaler cloud, so neither avoids the proxy detour.

Can I block personal ChatGPT but allow ChatGPT Enterprise without a cloud proxy?

Yes. dope.security's Cloud Application Control enforces the tenant distinction on the device during local SSL inspection, so the corporate tenant works and personal sign-ins are blocked without routing traffic to a data center. See the three-layer AI governance stack for the full model.

Do I need endpoint AI governance if I already have Netskope or Zscaler?

If every device always runs the proxy client, AI traffic is decrypted, and you have licensed the AI and DLP modules, you have partial coverage with added latency. If any of those conditions is false, prompts leak. dope.security covers browsers, desktop apps and IDEs from one agent with no module stack.

What is the best way to stop sensitive data going into AI tools for a mid-size company?

Deploy an endpoint agent that classifies prompts and uploads on the device and enforces enterprise-only AI accounts, then watch usage in one console. dope.security does all three from one agent under 100 MB of RAM, with policy live on every endpoint in under a minute.
