I have the impression that VPN is good, but then in How Apple’s New Find My Service Locates Missing Hardware That’s Offline, Matt McCaffrey said , “(using a VPN as a small measure of security)” and it made me wonder. Other threads on TidBITS Talk have mentioned https://encrypt.me, so I visited that site. It seemed to confirm that a VPN is not necessary if one is connecting using HTTPS.
Notwithstanding http://chronicle.com/article/Why-Privacy-Matters-Even-if/127461/ (an interesting article from 2011 that seems to be behind a paywall now, which makes me wonder how I got it), I wonder if using a VPN is worth the bother, time, and cost.
I do have access to a VPN server, and I almost always try to use it when I connect while not at home and not tethering through my iOS devices hotspot. However, the server seems to be down way too often (perhaps 10% of the time I try to connect). Also, the institution is still providing the 32 bit client software for MacOS (Cisco AnyConnect Secure Mobility Client 3.1.13015).
If VPN adds no security to an HTTPS connection and almost every web site I visit uses HTTPS, am I being excessively cautious using VPN? If I need VPN, is there a source for a 64 bit version of Cisco AnyConnect Secure Mobility Client? (I visited the Cisco web site and got the impression that there is a 64 bit version, but could not find a way to download it.) If VPN is a really good thing to have, is Encrypt Me a good company? (It sure seems like the 5 GB per month plan that I can turn on and off would satisfy my needs. On the other hand, my nature is to have as few accounts as possible, and using any commercial VPN provider would mean setting up another account.)
Thank you for any education or advice.
