25 Security Vendors To Watch

{EDITOR'S NOTE: This story has been updated to clarify that this list encompasses both emerging and established security companies.}

As cyberattacks become more complex and dangerous, security pros will be on the hunt for new technologies to protect their networks and information.

A wave of emerging and established security companies are bringing next-generation security technologies to enterprise users. These organizations have captured the industry's attention and are generating a lot of interest within the security community.

Their technologies span all aspects of the modern cybersecurity space, from mobile app security to cloud security. Their tools are aimed at helping organizations spot previously unknown cyber threats, detect attacks in real-time, and mitigate damage as soon as possible.

There are three key themes driving the cybersecurity market, says Scott Crawford, research director of the Information Security practice at 451 Research. They are: new approaches to endpoint threat prevention, security analytics, and the continued transition to the cloud.

These three trends will have a broader affect on the types of technologies offered by security vendors, as well as the tools businesses will implement and use to protect themselves from attack.

Here are some of these security companies and the technologies they offer. Some of these businesses are fairly new, but all are established and building interesting, game-changing technologies. This list is not scientific and by no means comprehensive; it's simply a sampling of vendors to watch.
