Stop Account Takeovers Before Attackers Break Through

When attackers target your sign-in workflows, they're betting you can't tell them from real consumers. Arkose Titan makes that bet unprofitable — stopping credential stuffing, malicious AI agents and every ATO variant in between before unauthorized access occurs, while real customers and trusted AI agents sign in without friction.

Account Takeover Is Getting Harder to Stop

AI agents are changing account takeover. Where legacy bots followed predictable patterns, malicious agents mimic human behavior, solve traditional challenges and rotate infrastructure to evade detection, while other agents sign in on behalf of real customers.

The 2026 Agentic AI Security Report finds 97% of enterprise leaders expect a material AI-driven incident within 12 months, yet 72% question whether their defenses will scale as AI-driven attacks continue to evolve. Telling a trusted agent from a malicious one — and deciding what each is allowed to do — is now part of protecting every sign-in.

01

Let Real Customers and Trusted Agents Sign In

Real consumers sign in without friction, and you set the rules for which AI agents can access accounts on their behalf.

02

Catch Threats Before They Break In

Nearly 1,000 detection signals identify suspicious sign-in attempts, recognizing AI agents and bots by their behavior even when they don't identify themselves.

03

Turn Every Sign-In Attempt Into a Losing Bet

Proof-of-Work validation and LLM-resistant challenges force attackers to burn through costly resources on every attempt, with difficulty scaling based on risk to keep friction minimal for legitimate consumers.

04

Adapt as Sign-In Attacks Evolve

True/false API results and rich session data allow for immediate action as attack patterns evolve, meaning defenses keep pace with attacker innovation.

Frequently Asked Questions

What is account takeover fraud?

Account takeover fraud occurs when someone gains unauthorized access to a legitimate user's account, often to drain funds, make purchases or steal personal information.

How are account takeover and credential stuffing related?

Credential stuffing is one of the most common ways account takeover happens: attackers test stolen username-password pairs from past data breaches until they find matches that unlock real accounts.

How do you prevent account takeover?

Arkose Titan analyzes signals such as device, behavioral and credential-risk data at sign-in, then routes suspicious sessions to adaptive challenges and invisible Proof-of-Work, stopping unauthorized access before an account is compromised.

What are the best account takeover fraud detection solutions?

The strongest solutions combine signals such as device, behavioral and credential data with real-time adaptive enforcement rather than a single static check. Arkose Labs backs this with a $1 million credential stuffing warranty.

Can AI agents be used for account takeover?

Yes. Attackers can use AI agents to test stolen credentials and mimic real sign-in behavior at scale, while other agents sign in on behalf of real customers. Arkose Titan identifies AI agents at sign-in so you can decide which to allow and which to block.
