Arkose Labs

Arkose Labs is a San Francisco-based fraud and bot management company whose platform is designed to stop automated attacks and human-driven fraud at scale. The company targets threats such as SMS toll fraud, account takeover, fake account creation, web scraping, card testing and credential stuffing, which impose direct financial losses and degrade the experience of legitimate users. Its approach differs from conventional bot detection in that it aims not only to identify malicious traffic but to undermine the economics of attacks, making them too costly and time-consuming for fraudsters to sustain. Arkose Labs backs this proposition with a warranty of up to USD 1 million against certain credential stuffing and SMS toll fraud losses for qualifying customers.

The Arkose Bot Manager platform evaluates each session using a wide range of device, network and behavioural signals, applying risk-based decisioning to classify traffic in real time. Low-risk users proceed without friction, while suspicious traffic is presented with adaptive challenges, branded as Arkose MatchKey, that are designed to be simple for humans but resistant to automated solving, including by AI-powered solvers and human click farms. Challenges escalate in difficulty as attack pressure increases, depleting the attacker's resources. Detailed dashboards and reporting provide visibility into attack patterns, and the company's security operations centre offers around-the-clock monitoring and threat intelligence support. Additional products address account security, email intelligence, device identification and protection against SMS pumping. Integration is achieved through client-side SDKs for web and mobile applications and server-side verification APIs, and the platform can work alongside existing content delivery networks, fraud tools and identity systems. Arkose Labs serves large consumer-facing businesses in sectors such as technology, gaming, social media, financial services, travel, ecommerce and telecommunications, where high volumes of logins, registrations and transactions attract sophisticated attackers. Deployment is delivered as a cloud service with professional onboarding. Pricing is quote-based and not published in this listing, and no information on a free trial or free version is provided here.
