The detection engine uses an open-source LLM that runs entirely inside a self-hosted environment

The cside AI engine detected that the modified script exhibited keylogger behavior and was flagged as malicious. Customers can then review the script and, if necessary, block the corresponding hash values.

cside is a cutting-edge client-side security solution designed to protect organizations from the growing threat of browser-based attacks. Unlike traditional security tools that rely solely on threat feed intelligence, cside employs a fully autonomous detection system that uses historical context and AI to analyze the behavior of third-party scripts. This proactive approach allows cside to identify and block potential threats before they can reach your users, ensuring robust protection against zero-day vulnerabilities and supply chain attacks. With its unique multi-layer solution, cside offers unparalleled defense for client-side applications, making it an essential tool for any organization looking to safeguard their web presence.

100 % session coverage, DOM-level diffing, conditional threat detection (geo/time/user cohort). c/side sits in the path of every third-party request, fetches the actual JavaScript, and inspects it in real time. So malicious code is blocked before the browser can execute a single line.

VikingCloud’s independent assessment confirms that, when properly configured, cside fulfills these requirements by continuously analyzing integrity and, if necessary, blocking scripts in real-time. The cside platform offers a dedicated PCI DSS dashboard that explicitly covers insights into 6.4.3 and 11.6.1 requirements.

cside only stores the requester’s IP address for incident scoping; that data is never brokered or used for advertising. All collected data remains in cside managed clusters hosted in AWS.

Stop Magecart, formjacking, token hijacking, cryptojacking, and more! By integrating client-side protection every third, fourth, and nth party script behavior is monitored for malicious signals. cside delivers full–spectrum visibility and control over all third party scripts executed in the user’s browser 100 % of the time without sampling.

By providing real-time payload inspection, automated blocking, full historical payload storage, and auditor-ready reports that map directly to the testing procedures in PCI DSS 4.0.1.

VikingCloud noted that the cside platform intercepted and blocked the third-party script actively to prevent data leakage.
