We have tracked security technologies for over a decade and scour the community for indications of new, virtuous technologies and companies that can help enable enterprise missions through better security.

The most virtuous of these firms focus on doing a small number of things well, or sometimes just doing one and only one thing very well. That is the nature of cyber security technology today. Threats are so complex and enterprises consist of such unique, mission-focused infrastructure that this can make it better for enterprise decision-makers. You can find the one firm that scratches your biggest itch and then move on to the next itch.

But the bad news is with every solution introduced another challenge then becomes the priority. Clearly this is a never ending cycle.

To help you with your continuous searches we maintain this list with continuous updates. The firms we report on below are among the best available. And these are firms with staying power, making them lower risk options. Please contact us for more information on any of them. And please let us know if you think we are missing anyone we should be reporting on.
