commercial SSH vs. OpenSSH
I'm not sure if this is appropriate for the forum, but I figured it was security related, so here goes...

I'm writing an anlaysis for my group about moving some of the old internet protocols (rsh, rlogin, etc...) to the SSH suite of tools. An outside security group recommended a commercial version of SSH (Tectia), but I'm not sure that it's worth paying for. I have lots of previous experience with OpenSSH, and I was wondering if the commercial version offered anything more than the open-source version. I understand that the open-source version does not use patented algorithms. Am I losing any level of security by using the open-source version over the commercial version?

Any info would be greatly appreciated!!
