A WAF inspects requests at the server edge; it sees headers and IPs, not what the browser actually is or does. A bot using a real browser engine from a residential proxy looks like a legitimate request to a WAF. Detection has to happen in the browser, where cside draws on 250+ browser, device, and network signals to reveal the automation a WAF cannot see.
Can cside work alongside my existing WAF without conflicts?
We monitor an entirely different dimension of the application stack; hence, there is no interference.
How does cside solve the client-side blind spot that WAFs can't address?
Cside analyses every third-party script on our side before it runs, making it easy to stop attacks by analyzing JavaScript content asynchronously and hashing a list of bad scripts, preventing them from being loaded again.
Why is the browser environment invisible to WAF monitoring?
A WAF (Web Application Firewall) operates at the perimeter, analyzing traffic as it crosses between external networks and your internal network towards your web servers.
Can a WAF protect against supply chain attacks on third-party JavaScript libraries?
WAFs cannot protect against client-side supply chain attacks because they don't intercept the fetch to the 3rd party endpoint and therefore have no visibility into the JavaScript files from the 3rd party sources.
