Frequently asked questions
How can organizations improve application security without slowing down users?
Effective security should stop malicious activity without creating unnecessary friction for legitimate users. Fastly combines edge-native protection with accurate, developer-friendly controls to help teams defend applications and APIs while maintaining performance. Security teams can fine-tune protection down to individual rules or endpoints without making security a roadblock to application delivery.
Why stop application and API attacks at the edge?
Stopping attacks at the edge prevents malicious traffic from reaching application and origin infrastructure. Fastly applies security controls across its edge platform to protect applications and APIs from application-layer attacks, bots, automation, and DDoS attacks while allowing legitimate traffic to continue without unnecessary friction.
How can organizations protect and monitor APIs they don't know about?
APIs can exist outside the visibility of security teams, creating gaps in application protection. Fastly API Security helps organizations discover, protect, and monitor APIs, including previously unknown or hidden APIs. This gives teams greater visibility and control over the APIs interacting with their applications.
How can businesses manage bot and AI agent traffic?
Effective bot management requires distinguishing automated traffic from legitimate users and deciding how different types of automation should be handled. Fastly helps organizations detect and govern bots, AI agents, and other automated traffic while minimizing friction for real users, with controls for identity, policy, and access as agent-driven traffic scales.
What should organizations look for in a web application and API security platform?
Organizations should consider protection for web applications, APIs, bots, automated traffic, and DDoS attacks alongside accuracy, ease of configuration, auditability, and flexible deployment. Fastly brings these capabilities together on one platform with granular controls, global policy updates, and visibility across security, delivery, and compute.
