Yes. cside deploys as a single first-party script tag (or the agentless Scan Method) on any web application, including multi-tenant SaaS, with no DNS changes and without routing your traffic. It monitors every third-party script your app loads and analyses what actually executes in each user's browser, so browser-based attacks such as skimming, XSS-delivered payloads, and compromised dependencies are caught per session. Because it works at the browser layer rather than per-tenant infrastructure, one deployment on your shared frontend covers every tenant. SaaS teams that also want fraud and bot or AI-agent detection get it from the same client engine, which powers Device Intelligence (250+ signals per session).
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.
