I was looking for an VPN provider and I was looking for one which also offer SSTP because the OVPN-client solution is not support as it is now.
I found one however they did not offer SSTP any more because the following reason: “SSTP protocol is no longer supported by XYZVPN and will not be supported in the future due to being old, outdated and not secure.”
Is SSTP indeed outdated as they say? That IPSEC is not absolutely safe and the NSA can read it (rumoured) is not a reason for me not to use it.
SSTP is not outdated and it is the most secure VPN protocol equivalent to OpenVPN. Infact SSTP can work where openvpn may not work due to its SSL nature. You must have misunderstood SSTP with PPTP. You can read more about PPTP and OpenVPN comparison here
SSTP connection starts as HTTPS connection, i.e. it needs to initialize TLS first, then it sends HTTP-like request and then it’s switched to SSTP. The established TLS channel is kept, so if this shouldn’t be secure, then no HTTPS connection would be secure either.
