Question: is pptp safe to use?
Answer: Not only is it easier, it's faster than other built-in protocols like L2TP/IPSec, SSTP, and IKEv2. But PPTP is widely regarded as obsolete. ... In short, don't use PPTP if you care at all about security when setting up a VPN. Instead, opt for a more secure protocol: OpenVPN, L2TP/IPSec, SSTP, or IKEv2.
