Fewer account takeovers after protecting login forms and back-end APIs.
Read the Case Study →Arkose Titan protects APIs, connected devices and programmatic endpoints from credential stuffing, account takeover and automated abuse, including the surfaces browser-based defenses can't reach, while real customers and trusted AI agents get through without friction.
API security is a top concern for 71% of cybersecurity professionals at large enterprises, according to Arkose Labs research.
APIs are multiplying fast: 25% of businesses say the number they manage doubled or more last year, according to Salt's State of API Security Report 2025. Many of those APIs are called by devices that can't run browser-based security, like gaming consoles, set-top boxes and in-vehicle systems. Others are accessed programmatically, machine to machine, through payment, social media and AI developer APIs. Attackers use both to run credential stuffing around the clock, create fake accounts, scrape data and hoard inventory without tripping browser defenses. Arkose Edge, part of Arkose Titan, protects these endpoints at the network edge, with no client-side code.
When bots bypassed the web forms at a leading U.S. fintech and hit its back-end APIs with about 30,000 credential stuffing attempts a day, Arkose Titan validated every request with a secure token, and account takeovers fell 75%.
Agents mostly use the front door. Send them to the one you built.
Most agents don't call your API. They drive your web UI as if they were a person, through the login page and the checkout. On business platforms the right answer is often a redirect rather than a block: detect the agent, hand it an agent-facing message, and send it to your MCP server or API where it belongs. The human-facing flows stay for humans, and your API sees the traffic you designed it for.
Arkose Titan validates every API request and extends protection to non-browser surfaces with Arkose Edge, stopping automated abuse before it reaches your back end.
Nearly 1,000 detection signals identify abnormal request patterns, unauthorized access attempts and replay token usage at each API entry point.
Adaptive challenges ensure only legitimate, authenticated sessions can obtain the tokens needed to call your APIs.
Arkose Titan identifies AI agents hitting your endpoints so you can decide which to allow and which to block.
True/false API results and detailed session data let downstream systems act immediately on every request.
Arkose Labs works. The proof is in the pudding. Since the implementation of Arkose Labs, we have not seen any attacks like the bot attacks that we experienced previously.
API security is the practice of protecting application programming interfaces from abuse, unauthorized access and data theft, typically by validating tokens and monitoring for abnormal request patterns at each entry point.
APIs often expose direct access to sensitive data and backend systems, and many are called by devices like gaming consoles, smart TVs and IoT products that can't run browser-based security, leaving them less protected than a website's front end.
Arkose Titan validates user tokens at every API entry point, analyzing signals such as request patterns and replay token usage to catch abnormal activity, then applies escalating defenses that only let legitimate, authenticated sessions through.
The strongest solutions treat API security as a continuous, adaptive layer rather than a one-time authentication check. Arkose Titan combines real-time risk signals with global threat intelligence shared across its customer network to catch abnormal activity as it happens.
API edge protection inspects and filters API traffic at the network edge, before it reaches your application. Because it doesn't rely on client-side scripts or SDKs, it can protect APIs called by consoles, smart TVs, IoT devices and machine-to-machine integrations. Arkose Edge works with existing API gateways and management platforms.
Yes. AI agents can call APIs directly, skipping the web interface entirely to test credentials, scrape data or automate abuse, while other agents call APIs on behalf of real customers. Arkose Titan identifies the agents hitting your endpoints so you can decide which to allow and which to block.
