c/side is a client-side security platform that monitors and secures third-party scripts running in website visitors' browsers. Unlike server-side security tools such as WAFs, c/side focuses on what executes in the end user's browser environment. The platform inspects scripts before they reach users, analyzes what each visitor's browser executes, and detects targeted attacks that may only occur for specific users, times, or locations. It maintains a full historical record of every script payload to support incident response. Core use cases include: - Credit card skimming prevention (Magecart-style attacks) - PCI DSS 4.0.1 compliance automation (requirements 6.4.3 and 11.6.1), including script inventories, HTTP header monitoring, and audit-ready reports - Outbound data privacy monitoring and cookie tracking - Chargeback fraud evidence collection - Job application fraud detection (Applicant Check) - VPN detection - AI agent detection The platform is designed to detect attacks that bypass Content Security Policy (CSP), including shadow DOM tricks and obfuscated code. It includes a privacy monitoring module (Privacy Watch) and a chargeback evidence solution. c/side holds GDPR, SOC 2, and PCI DSS certifications. It is available on the AWS Marketplace and integrates with compliance platforms such as Vanta. Every customer receives a shared Slack or Microsoft Teams channel for direct access to the security team.
