A good VPN provider cares about its customers and can offer a free trial version for the user to test and decide on a choice. Moreover, some VPNs will please you with a money back guarantee. If within 30 days of using the VPN, it does not suit you or does not satisfy your needs, you can take advantage of the return guarantee and be sure that you will get your money back.
A virtual private network (VPN) gives you online privacy and anonymity by creating a private network from a public internet connection. VPNs mask your internet protocol (IP) address so your online actions are virtually untraceable. Most important, VPN services establish secure and encrypted connections to provide greater privacy than even a secured Wi-Fi hotspot.
Through years of reporting and the Snowden leaks, we now know that the NSA's surveillance apparatus is enormous in scope. At one point, the agency had the ability to intercept and analyze just about every transmission being sent over the web. There are jaw-dropping stories about secret rooms inside data infrastructure hubs, from which the agency had direct access to the beating heart of the internet. With a VPN, you can rest assured that your data is encrypted and less directly traceable back to you. Given the mass surveillance efforts by the NSA and others, having more ways to encrypt your data is a good thing.
A P device operates inside the provider's core network and does not directly interface to any customer endpoint. It might, for example, provide routing for many provider-operated tunnels that belong to different customers' PPVPNs. While the P device is a key part of implementing PPVPNs, it is not itself VPN-aware and does not maintain VPN state. Its principal role is allowing the service provider to scale its PPVPN offerings, for example, by acting as an aggregation point for multiple PEs. P-to-P connections, in such a role, often are high-capacity optical links between major locations of providers.
The first step to security is usually a firewall between the client and the host server, requiring the remote user to establish an authenticated connection with the firewall. Encryption is also an important component of a secure VPN. Encryption works by having all data sent from one computer encrypted in such a way that only the computer it is sending to can decrypt the data.
