Is Cloudflare enough for your hybrid multicloud enterprise?
Cloudflare centralizes application delivery and security at the edge. F5 gives enterprises the flexibility to deploy these services wherever applications run.
Why enterprises choose F5
F5 gives enterprises the flexibility they need to deliver and secure apps, APIs, and agents across distributed hybrid, multicloud environments. Rather than forcing traffic to a single CDN edge ingress point, F5 secures data flows locally across your entire hybrid, multicloud footprint wherever applications run.
Distributed applications
Secure beyond a single edge
Consistent policy
Custom policies travel across environments
Hybrid environments
Proven security engineered for modern architectures
Risk control
Reduce dependency on centralized inspection
F5 vs. Cloudflare: key differences
F5 | Cloudflare | |
Protect public-facing web applications |  Protects internet-facing applications with WAF, API security, DDoS protection, bot management, and application delivery services. | Provides security and performance services for internet-facing applications delivered through its global network. |
Apply consistent security across hybrid and multicloud environments | Applies consistent security policies across cloud, on-premises, Kubernetes, and edge environments from a single platform. |  Security capabilities are optimized for applications routed through the Cloudflare edge. Organizations with highly regulated, data-sensitive, or on-premises workloads that require local security enforcement may require additional solutions. |
Discover APIs across all environments | Discovers APIs through traffic analysis, code scans, and across third-party gateways. | Discovers APIs primarily from application traffic routed through the Cloudflare edge. Does not provide the same breadth of discovery from code repositories, third-party API gateways, and distributed Kubernetes clusters outside the Cloudflare edge. |
Protect applications beyond the public edge | Protects public-facing, private, and internal applications, including applications that must remain on-premises due to regulatory, sovereignty, or operational requirements. | Best suited for public, internet-facing applications. Applications requiring local enforcement, customer-controlled inspection, or strict data residency controls may be limited by the need to transit traffic to the Cloudflare edge. |
Requires routing all traffic through the provider's network | Applications can be protected without routing traffic through a third-party network. | Traffic must be routed to the Cloudflare platform to be protected. |

Frequently asked questions
Cloudflare is highly effective for protecting internet-facing applications and edge-delivered traffic. Organizations with distributed applications, internal services, or hybrid environments typically require additional enforcement beyond a single edge architecture.
The primary difference is architectural. Cloudflare delivers security by routing application traffic through its global edge network for inspection and enforcement. F5 enables consistent enforcement both at our edge and within customer-controlled environments, allowing security policies to be applied closer to applications without requiring all traffic to pass through a single network.
Cloudflare is a strong fit for organizations prioritizing simplicity and edge-based protection for internet-facing applications.
F5 is a better fit for enterprises with diverse application environments—including private and internal applications, APIs, and Kubernetes workloads—where regulatory, data residency, or architectural constraints require security to be enforced within customer-controlled environments instead of routing all traffic through a single edge network.
F5 enables security enforcement within cloud, on-premises, and Kubernetes environments—including within customer-controlled infrastructure—so security policies can be applied closer to where applications and data actually reside. This allows organizations to consistently protect public, private, and internal applications, including internal APIs and east-west traffic, without relying solely on routing traffic through a centralized inspection point.
Both platforms support API protection, but they differ in how APIs are discovered and secured. F5 provides API discovery and protection across distributed environments—including internal APIs, service-to-service traffic, and applications running on multiple data paths—enabling visibility even for APIs that are never exposed through a public ingress. Cloudflare primarily applies API discovery and protection to traffic routed through its platform, which can limit visibility into APIs that exist outside its edge or on non-Cloudflare infrastructure.
