Building the next generation of web security

Accessible to all, no matter how big or small your venture

Our story

The mission

We're building the next generation of web security, accessible to all, no matter how big or small your venture.

Because security is not something we should put behind an unclimbable paywall. Starting with the best 3rd party script monitoring, performance and analysis engine. Using AI in clever ways to solve obscurity that actively blocked security for decades.

Established vendors in the cybersecurity space do not take client-side security seriously enough. This is a shame, as browser-side supply chain attacks are continuing to be a severe threat. Frustrated by the status-quo, we decided to build something better. A solution that offers such thorough security, in an elegant way, it allows security teams to rest assured, knowing this aspect of their security stack is well-protected.

cside was previously known as c/side (also written c-side).

Companies we've worked at

The team behind cside is made up from senior security engineers from the most forefront tech companies in the world. We're a fully remote team, composed of individuals who were friends before becoming colleagues, and now colleagues again. Every individual is dedicated to their core to provide the highest level of quality and care, and our product reflects that.

cside was founded by Simon Wijckmans, who was a product manager on Cloudflare Page Shield, co-chairs the W3C Anti-Fraud Community Group, and was named to the Forbes 30 Under 30 list. He was featured in WIRED for exposing North Korean IT workers infiltrating US companies.
