VPNs may allow for super-efficient communication between customer and company – but they rely on information which, if compromised, can cause huge losses. The Internet is still a frontier – sometimes so wide open it leaves us bewildered – and, like any frontier, the risks go hand in hand with potentially huge rewards. Virtual Private Networks for Dummies offers you a no-nonsense, practical guide to evaluating your company’s need for a VPN, understanding what it takes to implement one, and undertaking the challenging quest to set it up, make it work, and keep it safe.
