After a string of concerning news about some of the world’s biggest brands falling victim to cyber attacks (Insider Threats?), it’s only natural to devote a great majority of your security budget to defending your business from outsider threats. After all, if hackers can penetrate the gates of companies like Sony Pictures, Target, or the University of Calgary, then it should be evident that you must focus on hardening your security from the outside-in, right?


While cyber attacks are a danger, you mustn’t ignore or dismiss the risks that insider threats pose to your company. According to a report from Forrester Research, insider threats are the main source of data breaches. U.S companies alone lost $40 billion in 2014 because of employee theft and fraud.

However, in spite of the importance of keeping your network protected from malicious insiders, many businesses continue to ignore such breaches. That mentality must change. If insider security isn’t your focus yet, you should strive to educate yourself and stay up to date with the latest news.
