WAFs analyze incoming requests to determine if they're malicious, but third-party scripts are delivered from external CDNs and domains that your WAF considers legitimate. When a trusted script source like a popular analytics library gets compromised, your WAF continues to allow those requests because they're coming from a previously approved domain. The WAF has no way to analyze the actual JavaScript code content to determine if it has become malicious since the last time it was delivered.
Can cside work alongside my existing WAF without conflicts?
We monitor an entirely different dimension of the application stack; hence, there is no interference.
Does cside's JavaScript proxy add latency like a WAF does to all traffic?
cside only adds 8-20 milliseconds to specific dynamic JavaScript files we proxy, with static scripts cached for faster loading.
How does cside's approach compare to the complexity of managing a WAF?
cside is much simpler because we're only handling JavaScript files, not your entire web infrastructure.
What happens if cside's proxy goes down? Will my website break?
Your website will continue working as intended with our fail-open design and 99.99% uptime SLA.
