More Agentic AI Response Playbooks

Overview

For nine consecutive years DFIN experienced a 30% annualized growth rate in attack volume, leaving DFIN to face immense challenge: protecting its clients from sophisticated adversaries without overwhelming its security team with manual processes and alert fatigue.

A New Standard in Financial Security

With attackers leveraging AI to move faster, DFIN recognized the need to shift from their manual approach to stay ahead of evolving threats. By adopting the GreyMatter Agentic AI security operations platform, DFIN accelerated investigation and response times, empowering agentic AI response playbooks to take action on confirmed threats. The shift to agentic AI delivered:

  • 97% Faster Containment: Cut the mean time to contain threats from two hours to just three minutes by deploying agentic AI response playbooks.
  • 10x More Agentic AI Response Playbooks: Scaled from 17 to over 170 response playbooks run by AI agents.
  • Maximized Team Efficiency in Incident Response: Avoided the need for additional headcount for the ninth consecutive year, maximizing impact without driving cost.

Driving Business Outcomes

Though initially hesitant to allow AI and automation to take action on DFIN’s behalf, Senior Vice President & CISO Dannie Combs was thoroughly impressed by the positive impact GreyMatter had on cost and his team.

“We were absolutely stunned by GreyMatter’s accuracy and speed, which has really elevated our confidence. We have seen a definitive return on investment. To be quite candid, the speed of ROI was very surprising.”

This newfound efficiency has proved to be a game-changer for DFIN. “It used to be that to get faster, you had to spend a lot more. With agentic AI, we don’t need a small army of high-cost, extremely talented individuals on the team to grow. GreyMatter allowed those individuals to be redirected to more strategic activities.”

Our investment and overall adoption of GreyMatter is truly one of the most impactful decisions we’ve made over the last five years. Dannie Combs Senior Vice President & Chief Information Security Officer (CISO) at Donnelly Financial Solutions
