c/side Information

Browser security platform. Device intelligence, AI agent detection, fraud prevention, and script security. What happens in the browser is cside’s business. You’ve secured your servers. The browser is still a blind spot. Scripts, AI agents, and fraud all exploit the same gap: the browser layer your server-side tools cannot see. cside deploys as one first-party script tag. You get full browser-layer visibility into what scripts, users, and AI agents actually do inside the live session, in real time. Device intelligence Collect 250+ live browser, device, and behavioral signals to stop fraud as it happens. Detect VPNs, residential proxies, bots, and anti-detect browsers, then feed risk scores into your existing fraud stack as raw signals or pre-made alerts. AI agent detection AI agents (OpenAI Operator, Amazon Buy For Me) operate inside real browsers, bypassing WAFs and CAPTCHA. cside identifies them by what they do inside the session: scripted typing cadence, device fingerprint anomalies, autofill injection into payment fields, and absent mouse movement. Allow trusted agents. Block abusive ones. Fraud prevention Account takeover, multi-accounting, account sharing, fake profiles, stolen credit card testing, and fraudulent job applications. cside captures device fingerprints, browser state, and behavioral signals at transaction time, so chargeback evidence is ready before a dispute is filed. Script security and compliance Detect and block Magecart, e-skimming, formjacking, and third-party script compromise as it executes. Automate PCI DSS 4.0.1 requirements 6.4.3 and 11.6.1 with QSA-ready reports, validated by VikingCloud. Monitor third-party scripts for GDPR, CCPA, and HIPAA exposure, and manage CSP.
