If there's one area of the tech industry that's undoubtly growing - and growing fast - it's security. According to a recent report by Big Market Research, the Internet security market is set to grow at a rate of 8.1% per year between 2014 and 2020. As Internet-based technology spreads into nearly all areas of government, retail, IT and telecommunications, the threat of malware, spam and viruses has become an increasingly pressing concern. Fortunately, it's also an area where new security technology and insights continue to emerge.

Want to stay on top of new developments in this area? We've compiled a list of the most influential voices who are talking about it on Twitter.

Why this list? Well, it's based on Twitter data culled according to content, follower/following ratios, frequency of tweets, blog popularity, the opinions of other IT security experts and influencers, and our own subjective judgment.

One note: Some influential voices are not included, either because they don't have active Twitter accounts, or because they only tweet about IT security sporadically. Here, our goal is to provide the best possible stream of security news and insight.
