Detect 0-day attacks
c/side is crawling many sites to get ahead of new attacks. c/side is the only fully autonomous detection tool for assessing 3rd party scripts. We do not rely purely on threat feed intel or easy to circumvent detections. We also use historical context and AI to review the payload and behavior of scripts.
1 million scripts processed in last 24h
All scripts get processed by us to continually enhance our detection capabilities. We monitor over 70 attributes and use various AI-driven techniques to review the scripts, making our solution the most advanced detection system in the space to date.
