AI Security

Secure and govern AI everywhere innovation happens

Built on the network trusted by 80% of top GenAI companies, Cloudflare brings model traffic, MCP servers, AI apps, and data controls into one platform designed to work together from the start — and run everywhere in the world.

Reduce shadow AI risk

Understand how AI is being used across your organization. Combine SaaS analytics and traffic policy controls to manage risky or unsanctioned AI usage.

Prevent data loss

Detect sensitive information in AI-bound traffic. Apply policies to model requests, browser sessions, and SaaS destinations so users do not accidentally send sensitive data into external services.

Govern agent tool access

Centralize access to third-party and internal MCP servers. Curate which tools and prompts are exposed, and control access through zero trust policies.

Keep costs under control

Set real-time spend limits so AI usage stays predictable, even as teams work across multiple models and providers. Prevent runaway token costs without slowing down approved AI use.

Security across the AI lifecycle

Accelerate and secure agentic and GenAI adoption with a single unified platform

Secure workforce AI use
Get visibility into shadow AI and sanctioned GenAI apps, with app confidence scores and posture risk insights. Enforce zero trust AI controls to block, isolate, redirect, or allow access while reducing sensitive data leaks.

Govern AI agents
Secure AI agent access to corporate resources by centralizing MCP server connections behind a single URL. Enforce least privilege access and aggregate request logs for auditing, visibility, and control.

Build AI securely
Build compliant AI services faster with a unified control plane for routing, caching, cost control, and performance monitoring. Protect credentials and backend data with edge-stored secrets, guardrails, and secure integrations to internal APIs and identity providers.

Protect AI-powered apps
Protect public-facing AI apps with a single policy layer that discovers models and APIs across your web properties. Block prompt injection, model poisoning, abusive usage, and sensitive data exposure with a purpose-built AI firewall.

Take the fast path to safe AI adoption

AI Gateway

Centralize requests to AI models for security and cost control.

Remote MCP servers

Host MCP servers remotely, instead of locally on developer devices.

MCP server portals

Centralize MCP traffic for internal services and SaaS apps.

ZTNA (Access)

Enforce zero trust policies to authenticate and authorize all requests.

Built for this moment.

Everything teams need to build, adopt, and secure AI, running on one of the world’s largest and fastest networks.

Zero trust network access (ZTNA)

Secure AI access to verify users and devices before they reach AI tools and resources.

MCP server portals

Centralize agent-to-tool connections to govern access to approved corporate resources.

Secure web gateway (SWG)

Inspect AI-driven web traffic to block or redirect risky destinations and enforce policy.

Remote browser isolation (RBI)

Isolate high-risk AI browsing to keep untrusted content away from endpoints and protect data.

Cloud access security broker (CASB)

Implement AI security posture management (AI-SPM) to find and fix AI tool misconfigurations.

Data loss prevention (DLP)

Prevent sensitive data loss; detect and stop exposure in prompts, responses, and shared content.

AI Gateway

Manage model traffic; add visibility, rate limits, caching, and guardrails across AI providers.

Workers

Build and host remote MCP servers on Cloudflare to expose secure, scalable agent tools.

AI security for apps

Protect AI applications and block threats like prompt injection, abuse, and data leakage.

Applied Systems

"

We wanted to let employees take advantage of AI while keeping it safe. We prevent users from copying and pasting sensitive data from other apps into our isolated instance of ChatGPT, which prevents a lot of company info from being exposed to the tool. "

Tanner Randolph CISO

Frequently asked questions

What are the top risks of AI security?

Top AI risks include data poisoning, prompt injection, model abuse, intellectual property theft, and sensitive data exposure through AI model outputs.

How does Cloudflare secure AI?

Cloudflare secures AI with a unified platform that protects both internal workforce tools and public applications. It helps you discover unapproved AI usage (shadow AI), shield your models from abuse, secure how AI agents access data, and prevent sensitive information from being exposed in prompts.

What is AI security posture management (AI-SPM)?

AI-SPM constantly manages your AI security by finding and fixing model vulnerabilities. We simplify this with CASB integrations for tools like ChatGPT and Gemini that automatically surface misconfigurations and other security risks.

How do AI Gateway and Cloudflare One work together?

AI Gateway secures and manages model traffic, giving you visibility, controls, and guardrails for every request to and from AI providers. Cloudflare’s SASE platform, Cloudflare One, extends that protection across users, devices, and applications so AI usage stays controlled end to end.

What are the benefits of using Cloudflare for AI security?

Cloudflare provides unified security for public and private AI on a single platform. It protects the entire AI lifecycle with a future-proof global network, AI-powered threat detection, and model-agnostic controls, while also offering a platform that empowers developers to build AI apps securely.

Can you provide an example of how Cloudflare AI Security Suite works in a real-world scenario?

A remote employee tries to use an unsanctioned AI app to summarize a confidential document and includes prompts that suggest sensitive customer data may be leaving the company. Cloudflare’s SASE platform detects the shadow AI app, analyzes the prompt content and intent, and uses AI security controls to block or steer the request before sensitive data is exposed.
