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 β€” 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 β€” and deciding what each is allowed to do β€” is now part of protecting every sign-in.

Account Takeover

What changes when the attacker is an agent.

Agents now pass the identity checks built for humans.

Consumers hand their agents every login factor: the password, the one-time codes, the inbox they arrive in, the saved card. The agent logs in as the customer. Password, MFA and step-up all pass. Device trust misreads it: new hardware, new IP, new geography looks like a takeover when it is the customer's own agent.

MFA proves someone had the factors. It no longer proves a human was there.

Take over the agent, take over everything.

An agent holds the customer's credentials for every service it manages. Compromise the agent and every linked login falls with it.

Credential stuffing from the customer's own street.

Attack traffic now exits through the same residential pools as legitimate agents, with replayed biometrics that look human. IP reputation and behavior alone no longer separate them.

The false positive you didn't have before.

A customer's own agent on a cloud machine trips every device-trust rule you have. Blocking it is a locked-out customer who doesn't know why.

Detect the agent, not the credential. Device, compute and network signals expose a cloud agent even when every credential is valid. Agent ID recognizes a returning agent instead of reading it as a takeover. Score login, money movement and credential changes separately, and block every agent at the steps that matter.

Explore the Arkose Titan Platform β†’
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.

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.

How do you tell a customer's own AI agent from an account takeover?

Passing the password and MFA no longer proves a human is there, because customers hand their agents every login factor. Arkose Titan looks past the credential: device, compute and network signals expose a cloud agent even when every credential is valid, and Agent ID recognizes a returning agent instead of reading new hardware or a new location as a takeover. You can then score login, money movement and credential changes separately and block agents at the steps that matter.
