VPN Security Standard encryption. The security is minimum but better than doing without a VPN. Highest encryption. Verifies data integrity by checking twice. Highest level of encryption.Data gets thoroughly verified before being sent and received. SSL encryption included. Fastest and most secure VPN protocol. It makes you and your online activities anonymous on the web. Highest encryption. Verifies data with digital certification. This is the most secure VPN protocol amongst all which offers unparalleled security while you’re on the web.
VPN Speed Fast due to lower level of encryption. Relatively slow as it requires more CPU processing. Slow speed due to superior level of privacy and security. Fast VPN speed along with encrypted online connectivity. Smooth performing protocol. Fast speeds on high latency connections. Stealth VPN maintains a balance between speed and encryption.
Ports Used

PPTP uses TCP port 1723 and GRE Protocol 45

L2TP uses UDP ports -1701 and ESP protocol 50 443 4500 OpenVPN uses TCP port 80 and Port 53 for UDP. It also uses Multi-ports as well for TCP from port number 5500 to 55000 443 and 5500
Conclusion PPTP is easy to setup and delivers decent speeds. Less secure than other VPN protocols. Also, bypasses geo-restrictions L2TP delivers lower speeds because of encryption but allows you to bypass geo-restrictions SSTP is the most secure protocol that delivers exceptional privacy and security IKeV2 uses strong encryption and delivers fast browsing speeds OpenVPN performs great under high latency connections and provides strong encrypted connectivity Stealth VPN allows you to bypass firewalls and access restricted content from anywhere
