Frequently Asked Questions
How does CHEQ prevent account takeovers (ATO)?
CHEQ prevents account takeovers by evaluating every login and sign-in request in real time using a correlated intelligence approach.
CHEQ analyzes:
- Traffic signals to identify bots, automation, and AI-driven access attempts
- Behavioral patterns to detect credential stuffing and abnormal login flows
- Identity intelligence to verify whether the user behind the request is real, consistent, and legitimate
Based on this analysis, CHEQ can block malicious access attempts or trigger step-up actions before stolen credentials are successfully validated.
What role do AI agents play in modern account takeover attacks?
AI agents significantly increase both the scale and sophistication of account takeover attacks.
Modern AI-driven threats can:
- Mimic human browsing and login behavior
- Rotate devices, IPs, and fingerprints to evade legacy detection
- Generate or leverage synthetic identities to validate stolen credentials
- Bypass traditional CAPTCHAs and rule-based defenses
CHEQ is specifically designed to detect AI-driven impersonation and synthetic identity abuse, while distinguishing legitimate automation from malicious activity.
Can CHEQ detect credential stuffing attacks?
Yes. CHEQ is designed to detect and mitigate credential stuffing attacks.
Credential stuffing is identified through:
- High-velocity automated login attempts
- Reused or patterned credential combinations
- Botnet and network-level fingerprinting
- Behavioral signals are inconsistent with real users
CHEQ helps block these attacks before they impact authentication systems or customer accounts, reducing both security risk and infrastructure strain.
Does CHEQ add friction for legitimate users during login?
No. CHEQ is designed to protect accounts without introducing unnecessary friction for real users.
Key reasons:
- Detection happens in milliseconds during the request lifecycle
- Decisions are based on entity trust and identity consistency, not blanket challenges
- CHEQ maintains a false positive rate below 0.009%, ensuring legitimate customers are not disrupted
Only confirmed threats or high-risk sessions trigger enforcement or step-up actions.
How is CHEQ different from a traditional Web Application Firewall (WAF)?
CHEQ complements WAFs but solves a different problem.
While WAFs focus on:
- Infrastructure exploits like SQL injection or XSS
- Static rules and request patterns
CHEQ focuses on:
- Business logic abuse, including account takeover and credential stuffing
- Identity-based risk, not just request structure
- AI-driven and human-mimicking attacks that bypass traditional defenses
This makes CHEQ especially effective against modern ATO attacks that appear legitimate at the infrastructure level.
Can CHEQ work alongside our existing IAM or authentication provider?
Yes. CHEQ is designed to integrate with existing IAM and authentication platforms.
CHEQ:
- Evaluates risk and trust at the request level
- Sends signals to your authentication stack
- Enables step-up actions like MFA or secondary verification when needed
CHEQ does not replace your IAM provider. It enhances it by adding traffic, behavioral, and identity intelligence that IAM tools typically lack.
How does CHEQ detect synthetic or fake user identities?
CHEQ uses advanced identity intelligence to detect synthetic and AI-generated identities used in ATO campaigns.
Signals include:
- Disposable, invalid, or malformed email addresses
- Nonsensical or automated form inputs
- Behavioral inconsistencies across sessions
- Impossible travel, device anomalies, and identity cycling
These signals are evaluated in context to distinguish real users, legitimate agents, and synthetic actors with high confidence.
What types of businesses benefit most from CHEQ’s ATO protection?
CHEQ’s ATO protection is used by organizations where account trust directly impacts revenue and brand reputation, including:
- E-commerce and marketplaces
- SaaS and subscription platforms
- Financial services and fintech
- Higher education and enterprise platforms
Any business facing credential abuse, fake account activity, or AI-driven impersonation can benefit from CHEQ’s approach.
