cside
Computer and Network Security
cside is a client-side security platform that detects script attacks, AI agents, account takeover, fake account creation, and fraud at the browser layer. It is active runtime detection: it watches what scripts, users, and agents actually do as they execute in the live browser session, in real time, rather than relying on static scans or block-lists. cside automates PCI DSS 4.0.1 requirements 6.4.3 and 11.6.1 and deploys as a single JavaScript snippet, with no proxy and no DNS changes.
