A key market discriminator is threat intelligence - it makes all of the products that customers are buying smarter, more efficient, and allows them to sort the wheat from the chaff. That same intelligence allows security solutions, service providers and incident response teams to better defend customers, and the world, from malicious actors who seek to steal, disrupt, or destroy for a variety of motivations. In this world of threat intelligence the lines between what is proprietary/competitive advantage and what is in the greater interest are fuzzy. This session will discuss the calculus for sharing, and provide a forum to discuss ways to improve.
