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. Even in the event of an attack on popular libraries or CDNs, the malicious payloads continue to be delivered from the same trusted sources that your WAF has whitelisted. Your WAF still sees these compromised sources as legitimate requests and allows them through, not knowing that the contents have been weaponized by bad actors.
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.
How do conditional client-side attacks avoid WAF detection?
Sophisticated client-side attacks use conditional logic that only triggers under specific circumstances - certain geographic locations, specific times, or particular user behaviors.
