However, things do not just end here, as the VPN even offers plenty of advanced features. These include NAT Firewall for preventing malicious attempts on your network. Split Tunneling and SOCKS5 proxy for improved performance to download torrents and stream content online. Ad/Tracker blocking features to hide away those irritating adverts when browsing the internet.
For two years running, Private Internet Access has performed the best in our network tests and remained the cheapest full-fledged VPN service we've tried. It has more than 3,000 servers worldwide, supports platforms ranging from Windows and Mac to open-source routers, and lets you customize your tunneling and encryption protocols. You can pay in bitcoin, and you don't have to provide your real name.
If you use Intrusion Detection System (IDS) technology, you should know that if the IDS machine is between the Internet and the VPN concentrator that decrypts the encrypted packets (e.g., on a demilitarized zone—DMZ—network), it won't be able to detect intrusion activity that occurs between VPN-connected machines. Most IDS sensors match packet payloads to a database of intrusion signatures so that they know when to flag something as suspicious. If the packets are encrypted, they'll look like gibberish to the IDS machine. If you want your IDS machine to be able to monitor network traffic from VPN connections, make sure you place the IDS machine behind the VPN concentrator so that the IDS machine checks the traffic after the VPN concentrator decrypts it. You can't use an IDS on a software VPN, which operates directly from one VPN host to another.
Some VPNs offer “split tunneling,” which routes all traffic through your VPN except specific services or sites that you allow. For example, you might want to send your Web traffic through your VPN but stream Netflix on your fast, domestic connection. But these types of rules are complicated to implement without also leaking other important information, and we didn’t assess how effective they were in practice.
Your ISP may already be involved in some of these spying operations, but there's an even-newer concern. The FCC has rolled back Obama-era rules that sought to protect net neutrality, and in doing so allowed ISPs to profit off your data. The ISPs wanted a slice of that big data monetization pie that has fueled the growth of companies like Facebook and Google. Those companies are able to gather huge amounts of information about users, and then use it to target advertising or even sell that data to other companies. ISPs now have the green light to bundle anonymized user data and put it up for sale.
Computer and software providers work hard to make sure that the devices you buy are safe right out of the box. But they don't provide everything you'll need. Antivirus software, for example, consistently outperforms the built-in protections. In the same vein, VPN software lets you use the web and Wi-Fi with confidence that your information will remain secure. It's critically important and often overlooked.
