What do you like best about Cloudflare Application Security and Performance?
Cloudflare brings a cohesive application security and performance platform that consolidates WAF, bot mitigation, DDoS protection, CDN, and API security under a single, globally distributed edge network, reducing operational sprawl while improving coverage across layers 3 through 7.
The WAF combines Cloudflare‑managed rules, OWASP rulesets, and fully custom rules, with machine learning based detections and attack scoring that catch bypasses and variations beyond static signatures.
Managed updates arrive continuously, including zero‑day protections curated by the security team, which lowers rule maintenance effort and reduces false positives through large‑scale pre‑deployment testing.
Advanced rate limiting supports policies by IP, header, ASN, and country, which helps throttle abuse patterns without blunt blocking, and policies can return actions like block, log, challenge, or CAPTCHA when needed. IP reputation and exposed credential checks feed detections with real‑time intelligence and credential leak signals, which is especially useful for bot‑driven credential stuffing at the application edge.
API protections include schema‑aware and ML‑assisted detection, and the rules interface lets me compose policies from multiple signals such as Bot Score and Attack Score in a single place, which aligns security controls across web and API traffic consistently.
Client‑side security is covered to monitor and block malicious browser‑side resources, tightening the supply chain surface area from third‑party scripts that otherwise go ungoverned.
The platform integrates logging at request payload level with raw log access, SIEM connectors, and Terraform support to embed policies into CI/CD workflows, which keeps security configuration auditable and repeatable across environments. The dashboard’s unified Security rules experience brings WAF custom rules, rate limiting, API sequence rules, and client‑side rules together in one view, making posture and mitigations observable at a glance.
From a performance standpoint, the CDN is built on a very large global footprint, with data centers in over 330 cities and proximity within roughly 50ms to about 95% of the connected population, which materially shortens round trips for both static and dynamic content. Every service runs on every server in every data center, so content typically serves from the nearest location without specialized regional routing, and the scale is designed to handle traffic surges while maintaining latency targets.
Real‑world testimonials cite immediate performance lifts and cache hit improvements after migration, and the platform positioning emphasizes reduced origin requests and lower egress exposure via features like Cache Reserve.
The connectivity cloud framing is more than branding: application services are connected with global threat intelligence that blocks on the order of hundreds of billions of threats daily, and the same backbone used for security is leveraged to accelerate delivery of web apps and APIs. Operationally, deployment is DNS‑level with no hardware, and the service posture includes a 100% uptime guarantee at the service offering level with financial penalties, which is rare and signals confidence in resiliency.
Load balancing, free SSL, and detailed analytics round out the edge feature set, making the stack feel complete for both acceleration and protection in one plane.
What stands out in day‑to‑day use is the consolidated management model: one console, consistent analytics at request granularity, and ML‑assisted policies that reduce busywork without turning the system into a black box.
Platform‑specific WAF rule packs for major CMS and commerce platforms accelerate safe onboarding for typical stacks, while gRPC and WebSocket support means modern protocols are first‑class rather than afterthoughts. The approach scales from simple DNS onboarding to IaC‑driven policy management, which suits mixed teams across operations, security, and development. Review collected by and hosted on G2.com.
