Unfortunately, the Teleport open-source version has been discontinued and the free version doesn't allow companies above 100 employees or with more than 10 million dollars of revenue per year. Fair enough, everyone should live well.
But Teleport Enterprise is very expensive and I have been priced out. I don't know if I can share the price behind the "contact sales" but if you wonder about the price, you probably are too poor. In my case, it's quite a few orders of magnitude more than the time Teleport saves me.
So, I have been looking for a replacement that is open-source and likely to stay open-source for a while. I can pay for it, but I don't have a "contact us" budget.
For HTTPS, I never used Teleport and will stay with oauth2-proxy. For SSH, I found warpgate and sshportal, which may work but it looks a bit experimental. For Kubernetes, it's a mess but perhaps kubelogin could do.
If you replaced Teleport, how did you do it?
You’d still need something to sign the certificates based on some other identity of course (it can be done manually but kind of defeats the purpose) be it smallstep or something else
Since I was working in an environment where development teams tended to obtain root credentials from CI-CD pipelines and use them to change all the permissions on production servers or fill the storage with database dumps, I ditched teleport, ssh, and logins altogether! We followed the serverless model and there are no logins to any compute resource. The only way to bring data in is via unprivileged ci/cd pipelines or the application's API, the only way to get data out is via stderr or writing to a resource like S3. Nothing runs with privileges, there is no ssh, there are no admin-only access methods. Overnight that eliminated almost everything mysterious or unreproducible. No more permissions issues.
It supports to record each Session and save to various sources.
