cside is a browser-layer security platform that gives you visibility for every visitor, human or agentic. Security, fraud prevention, privacy and compliance, all from a single script. Unlike traditional WAFs and server-side security tools, cside operates directly in the browser environment, monitoring every third-party script loaded on your pages in real time. This means threats that bypass your backend defences are caught at the point of execution. What cside does: Script Monitoring and Control: cside inventories, monitors, and enforces policy on every third-party JavaScript tag running on your site. 100% session coverage, no sampling. Every script. Every page load. Detect supply chain attacks, shadow scripts, and unauthorised tag injections before they reach your customers. PCI DSS 4.0.1 Compliance: cside is the fastest path to meeting PCI DSS 4.0.1 requirements 6.4.3 and 11.6.1. Automated script authorisation, tamper detection, and continuous monitoring satisfy QSA requirements without manual effort. Validated by VikingCloud. Device Intelligence: Persistent, privacy-safe device intelligence using 102+ signals and 40+ hashed attributes. 99.7% fingerprint accuracy enables fraud prevention, bot detection, and session continuity across logins, checkouts, and account actions. AI Agent and Bot Detection: Identify and classify AI crawlers, headless browsers, and automated agents interacting with your site. Protect pricing data, inventory, and content from scraping and abuse. Chargeback Evidence: Capture cryptographically verifiable session evidence at checkout to dispute fraudulent chargebacks. Reduce dispute losses without adding friction to genuine customers. Who uses cside: E-commerce retailers, payment service providers, digital agencies, travel and hospitality platforms, iGaming and betting operators, financial services firms, and SaaS companies managing PCI compliance, fraud risk, and client-side attack surface across high-traffic web environments. Deployment: One-line script tag. No proxy. No latency impact. Up and running in under 5 minutes. SOC 2 Type II certified. PCI SAQ-D validated.
