Operating a corporate VPN solution can be expensive, and sometimes feel like navigating a minefield. With high stakes and a confusing sea of available solutions, mistakes are frequent and costly. Your VPN is a critical layer of defense in your corporate network, and intrusion can have serious consequences. Take the Target and Home Depot breaches for example: In 2014, these companies lost an estimated 120 million payment records due to mismanaging third party access to their VPN. A company VPN is indispensable for increasing employee productivity when working from home, or allowing third parties access to company assets for various reasons. However, you need to take a closer look at what makes a VPN secure and what some common pitfalls are so you can avoid them. When talking about VPN security, you may often associate it with transport security, e.g. making sure no one can intercept or manipulate your communication.
