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.
TorGuard is incorporated in St. Kitts and Nevis, and operates out of offices mostly in the US. But most people shouldn’t be worried about the legal jurisdiction of their VPN’s offices—we detail the reach of government surveillance above. In short, we think a privacy-focused VPN with public leadership that can be trusted not to collect information about their customers is a better choice in any country, rather than an opaque company run from the most liberty-ensuring country on the planet.

[...] VPNs using dedicated circuits, such as Frame Relay [...] are sometimes called trusted VPNs, because customers trust that the network facilities operated by the service providers will not be compromised.
And they manage to do all of this without sacrificing performance, offering one of the fastest download speeds (83 Mbps out of 100 Mbps) and the best 24/7 customer support in the industry. The only downside? It’s a little on the pricey side, with monthly plans starting between $6.67 and $12.95/mo. But it’s a small price to pay for excellent performance in almost every category.
