Secure Protect apps and APIs while accelerating growth AI is changing how fast you build, and how fast attackers move. Fastly helps you stop threats, control bots, and ship AI-powered products with confidence, without slowing your team down. Trusted by the world's leading companies Protection for your digital experiences Fastly secures your applications, APIs, and workloads at every layer, turning security from the "department of no" into an engine for growth. Layer 7 - Web app and API protection (WAAP) Stop client-side and server-side threats to your apps and APIs with one of the industry's lowest false positives. Learn more Compute - Secure-by-design compute environment A WASM compute environment isolates workloads to minimize or eliminate blast radius from zero-days. Learn more Client-side - Control over third-party scripts Gain visibility and control over the third-party scripts running in your users' browsers. Learn more Stop threats Stop threats from derailing big moments Cyber attacks are unavoidable; their costs shouldn't be. Fastly ensures uptime, availability, and protection automatically, cutting security incidents up to 30% and false positives 25%, with no constant tuning - so your biggest moments stay your best. SmartParse detection Analyzes the intent and context of every request for the lowest false positives with the least tuning. Network Learning Exchange Shared threat intelligence preemptively flags 54% of attacks before they happen. Automatic mitigation Intelligently spots and remediates attacks so they never stop your pipeline or your business. Highest mitigation capacity The fastest network with the highest capacity to absorb the world's largest DDoS attacks. Accelerate AI Accelerate AI innovation, minimize risk Ship faster without sacrificing protection. Fastly's security integrates into developer workflows to lift productivity 25% and conversion up to 8%, with predictable billing and no attack taxes - so you can adopt agentic AI with confidence. Developer-native security Deploys into developer workflows to cut friction and speed reviews before pushing to production. Secure-by-design compute A WASM environment isolates code with granular insights, minimizing blast radius from zero-days. Fair, predictable pricing No attack taxes or surprise overages; one bad month won't change your bill. Govern bots Govern bots without user friction AI scraping and AI-powered attacks overwhelm legacy defenses. Fastly gives you the granularity, flexibility, and intelligence to govern bot traffic on your terms, blocking bad bots and controlling AI access, while legitimate users pass through untouched. Adaptive Threat Engine Automatically separates attack spikes from legitimate surges like sales and viral moments. Dynamic Challenges Serves the optimal challenge, PATs for humans and CAPTCHAs for bots, reducing friction. Deception technology Patent-pending deception confuses attackers to fight the scale of AI-informed account takeover. Trusted by leading companies "Fastly Bot Management significantly reduced our unwanted bot traffic. The rule building, rapid signal visualization, and behavioral analysis all justified the investment." Randy Naraine Cybersecurity Architect Read customer story "As an engineering leader, I care deeply about the interplay between developer experience and security experience. Building trust with developers is easier with Fastly." Matt Brandman Senior Engineering Manager Read customer story "We've seen DDoS Protection activate multiple times. During an attack where traffic spiked over 17,000%, it automatically blocked the malicious surge before it reached our core services." Miguel Castillo Staff Software Engineer 17,000+ DDoS traffic auto-blocked 0 manual intervention needed Read customer story "Every time we needed a new feature, such as advanced rate limiting or bot protection, either Fastly already had it in place or it was on the roadmap and just a matter of months until we could implement it in the platform and deliver it to customers." Jan Haderka CISO Read customer story Frequently asked questions What does Fastly's security solutions help businesses do? AI is redefining the digital world in real time, but most security solutions weren't built to keep up. Fastly secures applications, APIs, and workloads at every layer, turning security from the "department of no" into an engine for growth. It helps teams stay ahead of evolving threats and bots with advanced detection, purpose-built capabilities, and a resilient global network. How does Fastly protect against both client-side and server-side threats to apps and APIs? Fastly's Layer 7 web app and API protection (WAAP) stops client-side and server-side threats with one of the industry's lowest false positive rates. It's one of three layers of Fastly's security model, working alongside Compute and client-side protection to secure applications and APIs end to end. That combination is designed to protect your digital experiences without slowing teams down. What is Fastly's secure-by-design compute environment? Fastly's Compute layer is a secure-by-design environment built to run application logic safely. It uses a WASM environment that isolates code with granular insights, minimizing the blast radius from zero-day vulnerabilities. That isolation is also core to how Fastly keeps productivity high while adopting agentic AI with confidence. Does Fastly give me control over third-party scripts running on my site? Yes. At the client-side layer, Fastly gives you control over third-party scripts. This is the third layer of Fastly's protection model, alongside Layer 7 WAAP and secure-by-design Compute, so client-side risk is covered along with your apps and APIs. How much can Fastly reduce security incidents and false positives? Fastly ensures uptime, availability, and protection automatically, cutting security incidents up to 30% and false positives 25% with no constant tuning required. The goal is to keep your biggest moments safe from the cyber attacks that are unavoidable, without their costs being unavoidable too. That protection is delivered without adding manual tuning overhead for your team. Turn security into a growth accelerator Whether you're stopping advanced threats, shipping faster, or taking control of bots, Fastly security helps your team move quicker, confidently.
