An Intellyx RSAC 2025 Brain Candy Brief
c/side was at RSAC demonstrating a lean web proxy layer that prevents unauthorized adware and malicious browser-based scripts from slowing down site performance, manipulating user sessions and intercepting user sessions and data.
“A lot of security people don’t necessarily know of this issue, but just in Q1 of 2025, we reported nearly 300,000 websites with client-side attacks on them,” said Simon Wijckmans, Founder and CEO, c/side. “To meet PCI compliance requirements, companies are already protecting the server side, and putting firewalls in front of their infrastructure, so bad actors know that it’s time to shift to an attack surface that isn’t monitored–the browser of the user.”
Any company with a robust web presence or e-commerce platform that needs to accept transactions, conduct customer support, or display user-generated content or media could stand to benefit from intercepting 3rd party scripts through this method.
