The Security Alert Fatigue Problem
Security teams aren’t short on dedication–they’re short on time. Many SOCs face more than 11,000 alerts a day, but lack the tools and context needed to prioritize what’s real. It can take days to confirm whether a file is malicious, and weeks to understand if that file or its variants ever existed across an organization’s environment. The outcome is as predictable as it is dangerous: wasted time, missed threats, and burned-out analysts.
Stairwell Intelligent Analysis Delivers Alert Triage, Done Right
Stairwell Intelligent Analysis changes the game. Powered by Stairwell’s platform, SIA goes beyond log data to analyze the files themselves which are the source of the alert. It draws on Stairwell’s unmatched inventory of threat intelligence.
“Every alert is a question about a file’s intent and history. SIA delivers the answers instantly, allowing security teams to move faster, make better decisions, and know they’re not missing what matters,” said Mike Wiacek, founder and CEO of Stairwell. “Stairwell is cutting through the noise to confirm what’s benign, flag what’s suspicious, and uncover the never-before-seen, including AI-generated malware designed to evade traditional defenses.”
Where most tools ask, “Does this file match something we already know to be bad?” Stairwell asks the better question: “What can this file do?” That shift in mindset is what enables SIA to deliver answers in seconds.
Key Advantages SIA Brings to Security Teams:
- Triage alerts in seconds. Fight alert fatigue. What used to take days, now takes seconds. Identify false positives instantly. Stairwell triages thousands of alerts every hour so you don’t miss a beat.
- Identify and analyze novel malware, including AI-generated. Stairwell helps you identify and analyze never-before seen malware that’s evading your existing tools.
