Despite all of the advances made in security over the past decade, it still takes organizations 15 times longer to close critical vulnerabilities than it does for attackers to weaponize and exploit them. In 2020, we’ll continue to see major enterprise-threatening breaches caused by known vulnerabilities for which a remediation was available. Organizations will have no choice but to radically accelerate the speed at which they harden their endpoints, with the most resilient adopting a new best-in-class response threshold of 24 hours for zero-day vulnerabilities and 72 hours for other critical exposures. Automation that delivers machine speed for endpoint hardening is required if organizations are to achieve defensible outcomes. Thus the 24/72 threshold will be the security metric that separates resilient organizations from those that suffer catastrophic breaches
