How secure are they and  what are the most reliable ?

Plenty of info and discussion on this in the IT forum.

 

MOVED.

Most modern VPNs are secure and reliable especially if you go for a well-known one. If you're willing to pay, NordVPN seems to be amongst the best. For a free one, TunnelBear is really good and incredibly simple to use.

Do not trust a free VPN service, due to that they do not have any responsibilities to you. They also offer a more bad service and not as many countries like you would want. The speed is also bad.

The best ones you have to choose from is Nord VPN and Express VPN, where I can vouch for Express VPN as the better one.

They are all secure if you enable encryption during the VPN connection.  Yes, you can have un-encrypted VPN connections depending on your VPN settings.   Now if you are talking privacy issues in terms of do they keep logs....give logs up to the authorities if required....well, you will see reviews which rates privacy issues and also reviews that are dead wrong about the privacy issues.   

 

VPN plans come in prices from high to lower.  ExpressVPN is one of the highest priced ones but also one of the best ones in terms of speed.  Nord is a mid to lower priced VPN provider with mid to high range speed.  I'm only mention those two since they have already been mentioned.  I do not use either...I use PureVPN which I'm happy enough with as I got it for around $1.15/month for 5 years.  

 

So, so many VPN now days to choose from....just google "Best VPN" or something along those lines and then read the reviews keeping in mind the review are often biased due to affiliation/sponsorship/ad payment from the VPN service. 

 

Below website constantly monitoring VPN speeds....not to imply this is the speed you will get from Thailand to wherever you are connecting to.

+1 for NordVPN

 

Currently halfway through my current 2 year subscription with them. Happy with them, speeds are good and connections are reliable. NordVPN keep no logs, are based in Panama, and if I check the connection against websites like  https://www.doileak.com/  or https://ipleak.net/  there is no indication of my actual IP address being leaked.
