When we named our company, we named it after the part of the web that no one else was protecting effectively: the client-side.
c/side = client-side.
Also commonly found written as cside on most social media platforms. And pronounced like seaside.
Every time someone loads your site or web app in their browser, they load dependencies you didn’t write or own. In other words, scripts you didn’t audit. It all runs in the browser. On their side. In the client of the user. And the server it comes from, you do not control and can be totally dynamic. And that’s where the real risk begins.
Most security tools stop at the server.We started where they left off.
That’s why we built c/side.To protect the code that actually touches your users’ browser.
The slash in our name?It’s a dividing line between what you control and what you don’t.Between your intentions and what actually gets executed.
We’re drawing a clear boundary.And we’re defending it.
With our name defined, our palm tree logo came naturally with the play on words.
Other spelling
It should be written as c/side, all lowercase.
Some write it cside (no slash).
Others write C/Side.
While we advocate to use the correct spelling, we embrace the others.
And we’re here to put client-side security on the map.
- Claiming ownership over what your users actually load
- Making invisible threats visible again
- Challenging the idea that the client-side is out of scope
We're building a platform that doesn't just patch the past, rather protects the present in its truest form. Today, browsers are the new OS, and scripts are the new supply chain.
So call us c/side.Call us cside.
Just know that we exist to protect the part of the web that everyone else forgot.
