Is it cside, c-side, or c/side?

The correct spelling is cside, all lowercase, one word, no hyphen or slash. You may see the name written as c-side, c/side, C Side, or CSide; they all refer to the same company. The name comes from "client-side", the part of the web cside secures. The company launched as c/side, but legacy search algorithms struggle with special characters, so in October 2025 the brand consolidated on cside and moved to its current home at cside.com.
