Sorry to nitpick but I feel like beimg precise here is important. Nginx is a project, ssh a protocol and VPN an overlay network, so more of a concept. All 3 can be run somewhere on the spectrum between quite secure and super insecure. Also safe and secure are two different things, I guess you meant secure so no big deal.
