Prosopo

Prosopo provides a privacy-first, risk-based security platform designed to protect websites, applications, APIs, and digital services from automated threats without compromising legitimate user experiences. Unlike traditional CAPTCHA solutions that present challenges to every visitor, Prosopo continuously evaluates the risk level of each interaction and dynamically applies the appropriate level of verification. This adaptive approach allows organizations to stop malicious bots, unauthorized web scraping, account abuse, and automated attacks while maintaining a seamless experience for genuine users. At the core of the platform is a sophisticated risk-scoring engine that analyzes a wide range of behavioral, environmental, and network-based signals in real time. Rather than relying on a single indicator, Prosopo combines multiple layers of intelligence to determine whether a request is likely to originate from a human user or an automated system. These signals can include browser characteristics, device attributes, interaction patterns, network reputation, and indicators commonly associated with automation frameworks and bot infrastructure. Based on the resulting risk score, Prosopo automatically determines the most appropriate response. Low-risk users may pass verification with an invisible Proof of Work (PoW) challenge that requires no active participation, while medium-risk traffic may receive a lightweight puzzle. High-risk requests can be escalated to image-based CAPTCHA challenges or blocked entirely depending on configured policies. This tiered enforcement model significantly reduces friction for legitimate users while increasing the cost and complexity of automated abuse. A key differentiator of Prosopo is its commitment to privacy and regulatory compliance. The platform is designed around the principle of collecting the minimum amount of information required to effectively identify abuse. Unlike some legacy bot mitigation providers, Prosopo does not depend on invasive user tracking, cross-site profiling, or extensive data collection practices. This privacy-first architecture helps organizations maintain compliance with regulations such as GDPR while still benefiting from enterprise-grade bot detection and abuse prevention capabilities. Businesses can strengthen their security posture without introducing unnecessary privacy concerns or creating additional compliance burdens. Prosopo protects against a broad range of automated threats that impact modern digital businesses. Organizations use the platform to defend against web scraping operations that extract proprietary content, pricing information, product data, and intellectual property. It also helps prevent credential stuffing attacks, account takeover attempts, fake account creation, spam submissions, click fraud, inventory hoarding, ticket scalping, loyalty program abuse, and other forms of automated exploitation. By stopping these attacks before they reach critical business systems, Prosopo helps reduce fraud losses, infrastructure costs, support overhead, and operational disruption. For organizations with more advanced security requirements, Prosopo's Enterprise offering extends beyond CAPTCHA-based verification and provides deeper threat intelligence and access control capabilities. Enterprise customers can identify and mitigate traffic originating from residential proxy networks, VPNs, anonymization services, Tor exit nodes, and other sources commonly used to disguise malicious automation. The platform can also detect suspicious TLS and JA4 fingerprint inconsistencies, helping identify bots attempting to impersonate legitimate browsers. Additional controls enable organizations to monitor and block traffic from abusive autonomous systems (ASNs), high-risk network providers, and known malicious infrastructure. These capabilities help security teams address increasingly sophisticated bot operators who rely on proxy rotation, browser spoofing, and distributed attack networks to evade traditional defenses. Prosopo's Enterprise platform also provides protection against spam email registrations, form abuse, API abuse, and fraudulent onboarding activity. Organizations can apply custom policies, risk thresholds, and rule-based controls to different user journeys, allowing them to tailor security measures to specific workflows such as account registration, login, password reset, checkout, ticket purchasing, or content submission. High-risk sessions can be challenged, restricted, or routed through additional verification steps, while trusted users continue through the application without interruption. This granular approach enables businesses to balance security, conversion rates, and customer satisfaction more effectively than one-size-fits-all CAPTCHA implementations. The platform is designed for rapid deployment across websites, mobile applications, and APIs, making it suitable for organizations ranging from startups and SaaS providers to large e
