Happy to chime in - Love the discussion ;-) Disclosure: I am the co-founder of Strong Network - a Swiss company. We are using and selling our own CDE solution.
My background is in cybersec and I worked at Snapchat after they acquired my previous (cybersec) startup - first time I saw the concept of CDEs, naturally I thought - can we combine productivity and security? This is what Ozrenko (my partner and ex Snap as well) and I decided to do.
Along with all CDE management functions, we designed infrastructure security mechanisms that are transparent to developers and that make their life easier (I and Oz are developers) - we realized that, we can expand the concept with a load of DevSecOps automation and eventually, we've hit very novel code security practices that we embedded in the environment (and filed patents on them).
Our security is mostly to keep developers chill while protecting the org (and reduce infrasec cost ;-) : protect all resource access credentials from leaking (phishing and malware), we provide data loss prevention (IDE, web apps), we detect secrets and prevent sprawling, we detect external code pasting in the code base, etc. All transparently and no hassle for the dev team - everybody gets free SSO to any resources!
Most importantly, we have hardened the platform at very complex organizations such as Broadcom, SwissRe, Niantic Labs and others with our self-deployed platform - you can imagine the difficulty of running efficiently across WAF, traffic proxies, VDIs and SASE. Oz is the man for that.
So in summary - we have today the most advanced CDE platform that provides both efficiency and security for all your resources and assets. We are a Swiss company working world-wide (greetings from Tokyo this week), so if you are motivated to join us (any function), please let me know!
Sadly, we have not chosen a codename for the platform yet.
