In today’s online world your data is never completely safe. Because we’re always connected, it means that somehow, somewhere, someone can access our information. We’re a culture dependent on online connectivity; we need it, we yearn for it, we can’t live without it.

But our compulsive need to be constantly connected leaves us vulnerable. Hackers are able to steal information from us without leaving a trace.

Now is the time to bolster your defenses and be better equipped for such attacks. And the way to do this? Easy. Get off those public networks and start using a VPN (Virtual Private Network).

Be smart and be secure

Let’s put it this way: when you surf on a public network you’re swimming in a public pool of hackable data with everything on show and no defense. If you’re working remotely from a public network and need to access data that could be very sensitive, like your company’s private log-in details, you’re putting all that data at risk because the network is not secure.

What a VPN does for you

Virtual Private Networks enable you to access private networks securely with complete peace of mind, so you don’t need to live in fear when accessing or sharing data remotely. We all like our online privacy, whether we’re torrent hounds, concerned data experts, or just scared of “the man” getting on our back. Using a VPN is the best way of protecting yourself and securing your sensitive internet details and traffic.

How a VPN works

A VPN is a WAN (Wide Area Network). It works a bit like a firewall, but the main difference is that it disguises your network. It gives you an alternate physical location, and changes your IP information, allowing you to slip through content filters and government censorship. You could be in London but your network suggests you’re in New Jersey.

VPNs use a number of connections and encryption protocols to generate virtual P2P connections which defend your data from potential threats. It’s super easy to establish this secure link. Say you want to access your private company network remotely. All you do is connect to the internet through the usual ISP, then proceed to link your VPN with the company’s VPN server using client software. The client software connects and gives you remote access to your company’s precious data – securely, of course.

How to find the right VPN

There are plenty of VPN providers to choose from. Although they share many similarities, each VPN offers something differentwith a varying levels of security. Although you can find free VPNs, these are usually compromised in terms of bandwidth, range of protocols, and encryption. The cost of a VPN service can range from one provider to the next, and it’s usually more affordable to purchase a yearly subscription. Many offer a free test period or money-back guarantees, so there’s no need to fear being stuck with a VPN service you’re unhappy with. You’re data is precious, so you want to be able to trust your VPN security!
