cside is a client-side security solution designed to help organizations protect their websites and web applications from advanced client-side threats such as script injection, data skimming, and browser-based attacks. As traditional security measures often overlook these vulnerabilities, cside addresses the growing need for comprehensive protection against risks associated with third-party JavaScript and web supply chain vulnerabilities. By focusing on real-time visibility and control over third-party scripts, cside enables organizations to safeguard sensitive data and uphold user privacy. Targeting businesses that rely heavily on websites and web applications, particularly in the e-commerce sector, cside offers a proactive, hybrid proxy-based protection model. This model not only helps organizations meet compliance requirements such as PCI DSS 4.0.1, DORA, and GDPR but also ensures that performance remains uncompromised. With the rise of sophisticated cyber threats, the need for a robust client-side security platform has never been more critical. cside empowers organizations to take control of their client-side security by providing tools that can intercept and analyze scripts before they reach the user. One of the standout features of cside is its hybrid proxy model, which allows for the interception of attacks before they occur. Unlike other solutions that rely on purchasing malicious domain intelligence, which can be slow and reactive, cside's approach captures the full payload of scripts delivered to users and conducts real-time analysis. This capability is essential for understanding the exact code impacting visitors, providing organizations with the insights needed to mitigate risks effectively. Many existing solutions, such as Content Security Policy (CSP) or JavaScript agents, lack the ability to perform this level of analysis, making cside a unique offering in the market. In Q1 2025, cside's homegrown detection engine identified over 300,000 unique client-side stacks, showcasing its effectiveness in helping e-commerce companies detect and respond to threats rapidly. By stopping attacks before they become widespread knowledge, cside enhances the security posture of organizations and minimizes the potential for data breaches. The platform offers a free entry point for users to get started, with additional features available in the business tier that provides enhanced visibility, retention, and control. For larger organizations managing multiple domains and extensive scripts, the enterprise level of cside is tailored to meet their advanced operational needs. Overall, cside represents a significant advancement in client-side security, offering organizations the tools necessary to navigate the complexities of modern web threats while ensuring compliance and protecting user data.
