prosopo.io received a security score of 63 out of 100 in Guard's comprehensive security analysis, classified as "Moderate Risk". This report covers PROSOPO LIMITED (UK)'s website security posture. PROSOPO LIMITED (UK) operates in the Technology industry in United Kingdom.

Prosopo Limited is a UK-based technology company specializing in advanced CAPTCHA and bot protection solutions. Their flagship product, Procaptcha, offers a dynamic, proof-of-work CAPTCHA system designed to provide superior bot defense while maintaining user privacy and GDPR compliance. Positioned as a cost-effective alternative to Google reCAPTCHA and hCaptcha, Prosopo targets businesses and website owners seeking robust security with minimal user friction. The company emphasizes ease of integration, customizable difficulty levels, and a privacy-first approach with no centralized data storage or user tracking. Technically, the website is built using modern web technologies including Eleventy static site generation, JavaScript libraries like PrismJS and Font Awesome, and is hosted with Cloudflare DNS services.

Business Intelligence

Market & Strategic Analysis

Prosopo operates in the competitive CAPTCHA and bot protection market, differentiating itself through privacy-first design and cost-effective pricing. Their SaaS model targets small to medium businesses and enterprises needing scalable bot defense. The company leverages partnerships and integrations with popular platforms like WordPress and Shopify to expand reach. Customer testimonials and Trustpilot reviews indicate positive market reception and effective bot mitigation. The transparent pricing calculator and free tier encourage adoption. Prosopo's growth potential is supported by increasing demand for GDPR-compliant security solutions and rising costs of incumbent CAPTCHA providers. The company maintains active community engagement via Discord, GitHub, and social media, fostering a supportive ecosystem.

Security Posture Analysis

Comprehensive Security Assessment

Prosopo demonstrates a solid security posture with HTTPS enforced and a Content Security Policy in place. The website does not expose sensitive data or use vulnerable libraries. Privacy compliance is strong, with no user tracking or centralized data storage. However, the lack of DNSSEC reduces DNS security, and no explicit security policy or incident response contact is published, which could hinder vulnerability reporting and incident management. The absence of a security.txt file limits transparency for security researchers. Overall, the security maturity is good but could be enhanced by adopting additional headers (HSTS, X-Frame-Options) and formalizing security policies.

Strategic Recommendations

Priority Actions for Security Improvement
