Kasada Bot Defense
Invisible bot defense and AI agent trust that stops bots, scrapers, and fraud without CAPTCHAs.
Kasada Bot Defense Overview
What it does
Kasada Bot Defense protects websites, mobile apps, and APIs from sophisticated bots, scrapers, and automated attacks before they reach the backend. Instead of CAPTCHAs or rule maintenance, it uses invisible client-side challenges combined with server-side detection, in a dynamic defense-in-depth architecture built to stay unpredictable and expensive to attack as adversaries retool. The same platform and detection engine extend to AI agent governance, allowing verified AI agents and crawlers while restricting or blocking untrusted automation, and to account-level fraud signals that surface takeover and repeat abuse.
How it works
Hundreds of sensors invisibly collect traces of automation within the client, detecting bots from the first request, while client validation checks the returned data for signs of automation and tampering. Server-side analytical models based on trillions of bot interactions identify automated session behavior in less than 2ms, and defenses adapt in seconds to counter retooling. Traffic decisions are enforced inline through one of three server-side integrations (NPM packages for CDN edge compute platforms, a low-latency proxy requiring no server-side code, or a customizable API called from any application backend) with client-side JavaScript and mobile SDKs. For AI-driven traffic, agents and bots are classified by verification strength, from cryptographic Web Bot Auth signatures to weaker signals such as user agents and IP ranges, and granular per-agent permissions are enforced by HTTP method, with dashboards and log export separating crawling bots from agentic bots. Account Intelligence links devices, accounts, emails, and behavior through a high-fidelity DeviceID to expose account takeover, coordinated fraud, and checkout abuse.

Key Capabilities
mapped to solution categoriesDetects automation through layered client-side and server-side detection models - behavioral, device, network, and challenge signals - resilient to AI-driven evasion and CAPTCHA-solving services.
Establishes and manages trusted relationships with legitimate AI agents: an out-of-the-box library of known agents plus granular per-agent permissions and policies governing what each agent may access and do.
Protects account creation, login, and session flows against credential stuffing, account takeover, and fake-account abuse, building per-account trust from user, device, and session signals.
Protects high-value transaction flows (checkout, payments, hype sales, registrations) from automated abuse while prioritizing legitimate human and agent-delegated transactions.
Detects and governs content scraping, including LLM training and retrieval crawlers: blocking value-damaging scrapers while permitting or monetizing sanctioned automated access.
Determines and surfaces the intent behind automated traffic - distinguishing malicious bots, benign automation, LLM crawlers, and human-delegated AI agents - so policy decisions rest on what the traffic is trying to do, not only whether it is automated.
