looked at the report to see if they'd reviewed torguard and apparently they... don't realize it's a VPN service and think it's related to the onion router. Kinda undermines they're credibility a bit if they can't even identify the tools they're auditing properly.

Actually, their report is much more credible because they note the difference between TorGuard (and a few similar apps) vs normal VPNs. To actually quote the report[1]: 67% of Android VPN apps claim to provide traditional VPN services (labeled here as “VPN clients”) including enhanced security and privacy, anti-surveillance or tunnels to access geo-filtered or censored content. Note that we consider Tor clients (e.g.…

Tor == "The Onion Router".

TorGuard == something completely unrelated to Tor. Per the TorGuard website (https://torguard.net/faq.php):

"Is TorGuard related in any way to the “tor” project? No, The reference to "tor" in TorGuard relates to "torrents" and guarding one’s privacy when using bitorrent. We are not related in any way to the “tor” project however the company does support through donations."

Orbot, OTOH, is part of the Tor Project (https://www.torproject.org/docs/android.html.en) and Globus (https://play.google.com/store/apps/details?id=com.globus.vpn...) claims to support Tor.

Why would you need a third party app on Android? I just use the native VPN support over ipsec. Or are people using them for older Android installs?

What I've noticed is that if you pay for premium service, the apps keep the connection up way better and offer nice features, like switching your country from an easy menu.

Tha being said I've been quite happy with http://privateinternetaccess.com/. A good Android client, fast, don't ask any personal information when you register, they say no logging, the Android app doesn't ask any permissions and so on. I can choose the key length and additionally block all connections if the VPN is not connected.

Well that's.. stupid.

Ok, I entirely agree they (and I) are wrong. But obviously I'm going to take the position that it isn't unreasonable to think something called "TorGuard" has something to do with Tor.

TorrentFreak maintains a list of providers that responded to a questionnaire about anonymity, including one about encryption used: https://torrentfreak.com/vpn-anonymous-review-160220/ Personally, I prefer the "roll your own" approach mentioned above. A VPS from DigitalOcean or something beats most providers' pricing.

> A VPS from DigitalOcean or something beats most providers' pricing. Does it? A VPN subscription costs around $40 a year, DigitalOcean starts from $60 a year for the lowest level standard droplet. Am I overlooking something?

You can get a VPS for far cheaper than DO's prices.

I'm currently posting through a VPN running on a VPS I discovered through Low End Box, works just fine for browsing and downloading. 500GB transfer per month for $10 a year.

It is no surprise that 'free' VPNs don't work or compromise security. Would be good to see the actual list of VPNs that comply with basic security requirements.

There is no anonymity if you roll your own.

The whole idea of VPN providers is that a lot of users have a connection to the same server so it's hard to monitor who talks to who.

One side effect of schools blocking websites is students downloading and using free VPN software. They have no money, and it works well enough for "unblocking" websites as far as they're concerned. Rip privacy.

Can you elaborate where you are seeing this? Is this as the post-secondary level or lower? I worked in higher-ed in the US and almost uniformly our institution and those we talked to in mailing lists were adamantly anti-blocking. Remembering back to when I was in HS and our library was outfitted with a few donated computers that shared a 56k connection, I know they had a net-nanny installed, but that was quite some t…

Schools blocking stuff is very active still- it's extremely prevalent up to and including high school, and only a handful of colleges do any sort of filtering.

Furthermore, kids find increasingly shady free vpns as IT blocks more and more free vpns.

Lots of kids will use free vpns to get their SAT/ACT/AP scores a day or so early.

People should NOT trust free VPN services at all, as you don't pay level of service is not guaranteed. What's worse, who knows what the service provide is doing with the data flowing through the tunnels (to)? cover the operational cost (and goal for profits) Install and configure your own VPN services (IPsec or OpenVPN), use strongSwan (Android native client which works great with RSA authentication with x509 certs,…

FTFU.

> People should NOT trust free VPN services at all, as you don't pay level of service is not guaranteed. The corollary is that ones you pay for should not be trusted either: a service can both take your money and insert ads. huh.... reminds me of pay/cable tv....

Actually, I missed this point. Thank you for pointing out ;-)

I think that's why more and more open source tools (scripts or automation {cook,play}books, etc.} have been made available to enable people to self serve and build their own VPN service ;-)

You don't get anonymity with a VPN…
