Real-time browser attack visibility requires a tool that instruments the browser itself, not one that reads server logs after the fact. cside captures script execution events, device fingerprints, AI agent signals, and fraud indicators across every session and fires alerts to Slack, Teams, email, or webhooks instantly. WAFs and edge security tools operate before the browser renders the page and cannot see what scripts do once loaded. For script attacks, formjacking, and AI agent fraud, detection has to happen at the browser layer.
How do client-side attacks actually happen?
Compromising a third-party service your website relies on is one common way attackers get in.
Why can't traditional security tools detect client-side threats?
Firewalls, WAFs, and vulnerability scanners are traditional security tools used to protect your server, but they cannot see what's happening in your users' browsers.
What's the difference between client-side security and server-side security?
Server-side security protects your infrastructure, while client-side security focuses on where your application actually runs, inside your users' browsers.
What's the difference between client-side security and application security?
Client-side security is a critical subset of AppSec that focuses on protecting applications where they actually execute--in users' browsers.
