Francis Bacon said: “Knowledge is power”, which is perhaps why a VPN is becoming increasingly crucial to many internet users. There is an abundance of information available on the internet, much of it personal, and many of us are unwilling to see that information fall into the hands of hackers, government moles or advertisers. As VPN technology becomes ever more erudite, so does the process of selecting the right product. One of the benefits of PIA VPN is that, as a US-based company, it doesn’t have to abide by data retention laws that affect providers such as Overplay in the UK. Overplay’s advantage over PIA is its compatibility with a range of devices. In this competitive world, affordability, speed, server location and abundance and customer service are all key and, sadly, Zenmate battles to stay in the competition in any of these categories. Limited servers and poor customer service are particularly damaging to Zenmate’s appeal.
