Client-Side vs Server-Side Monitoring: Why You Need Both

Your SIEM, WAF, and EDR tools work overtime to protect your infrastructure. But what about your browser layer?

Here’s the difference:


LayerServer-Side ToolsClient-Side Monitoring (Breachfin)
Sees Requests✅ Yes🚫 No
Sees Scripts🚫 No✅ Yes
DOM Changes🚫 No✅ Yes
Real User View🚫 No✅ Yes
Detects Magecart🚫 No✅ Yes

Why Both Matter

  • WAF stops DDoS and SQLi — but can’t stop injected JS
  • SIEM logs backend activity — but can’t see DOM mutations
  • SCA audits code — but doesn’t inspect what’s actually running

Breachfin Complements Your Stack

Think of Breachfin as:

“Your browser-side detection & alerting engine”

We monitor what your users experience — from DOM changes to script drift — and send the data to your SOC in real time.


You protect your servers.
