Overview

In this highlight from our recent webinar on modern versus legacy Attack Surface Management (ASM), Assetnote co-founders Michael Gianarakis and Shubham Shah share an example of how one customer broke their remediation record using Assetnote.

They also discuss the increasing threats to attack surfaces and provide real-world examples of how:

  1. Threat actors are weaponizing security vulnerabilities faster - as soon as patches are released and disclosed.
  2. Ransomware groups on the dark web are beginning to identify novel zero-day vulnerabilities, becoming more proactive in their approach to targeting organizations.

So what's the takeaway? Speed is critical. All organizations should be looking at their time to mitigation (TTM) and ensuring their teams are empowered with access to relevant and highly targeted security research.
