Privacy-first bot detection and fraud prevention for the web
Multi-layered detection delivers risk scores and near-zero false positives, with passive and no-CAPTCHA modes.
Stop transaction fraud, account takeovers and multi-accounting with privacy-preserving signals and no PII.
A stronger, toll-free alternative to SMS MFA that reduces fraud while simplifying the user experience.
Build custom risk models with adaptive learning and enrich your own ML using blinded, compliant signals.

Attack-led AI security testing and red teaming
Agent-native reconnaissance maps models, agents, tools, instructions, permissions and behaviours the way an attacker would before launching attacks.
Continuous, adaptive testing of AI agents and systems against evolving attack techniques, rather than one-off audits.
Findings are backed by a knowledge base built from more than 175 publicly disclosed AI vulnerabilities across major AI systems.
Runtime protections and remediation guidance help close defensive gaps and verify that fixes actually hold.
