VPN Protocol vs VPN provider


New member
Hello everyone! I wonder about the relation between VPN protocols and the VPN Provider, can it be different using same protocols with 2 different VPN providers? For example IKEv2 is said to maybe be compromised by NSA, it is an issue can not be ignored, the providers i asked said its not an issue tho cause their VPN can not be compromised and you are just as good of with any of their protocols. Are they telling the truth? Or is it the provider handling the encryption aside of the protocols?
