How a Global Financial Institution Built Deeper Detection and Greater Assurance with Stairwell
business challenge
This global financial institution already had a sophisticated security operation: multiple EDRs and sandboxes, plus dedicated detection engineers, threat hunters, and specialized security teams around the world. The challenge wasn’t finding more alerts. It was knowing what they had missed, and confidently ruling out what they hadn’t.
The CISO wanted to go deeper than traditional endpoint, email, and network analysis, with the ability to understand suspicious files before execution and investigate them across the entire environment.
“It’s really good to find problems in cyber. It’s much harder to rule them out. How do you rule out five million alerts? Stairwell does that for us.”
WHY STAIRWELL
The team wasn’t looking for another sandbox or another replacement for its existing stack.
It wanted a fundamentally different layer of visibility.
Stairwell analyzes what files are written to do, identifies related variants, and lets security teams search across their historical file data in all time.
“Stairwell had the kind of deep analysis
we couldn’t get anywhere else.”
That gave the team the ability to answer a critical question quickly:
Has this file, campaign, or related malware ever touched our environment?
From deployment to value in weeks
“ When Stairwell brings something up, we all pay attention. The value is that it’s quiet until it’s not. ”
Stairwell was deployed region by region across the global environment.
Full rollout took
3 WEEKS
Within weeks, Stairwell was identifying real issues while also helping the team confidently rule out false ones.
From threat intelligence to an answer
Today, Stairwell is embedded across the institution’s security workflows.
Threat hunting, vulnerability management, and SOC teams use Stairwell to:
✓ Search new IOCs against historical enterprise data
✓ Discover related malware variants
✓ Determine whether new campaigns have touched the environment
✓ Understand suspicious files quickly with AI Triage
✓ Confidently prove or rule out impact
“It’s really good to find problems in cyber. It’s much harder to rule them out. How do you rule out five million alerts? Stairwell does that for us.”
The result:
quiet confidence
When a highly suspicious file entered the environment, Stairwell analyzed the file,
provided the full scope of impact and delivered remediation steps when other tools could not.
“We were able to show exactly what it did and make a confident determination, even when others couldn’t.”
For the CISO, that’s the real measure of success.
“The less Stairwell finds, the happier we are. We know it’s working because we’re continuously running new intelligence through it and it keeps us covered.”
