Our company

We empower you to outsmart attackers

Conference Call
Inside Out Security

Security that starts on the inside

Stairwell believes in forging a future in which any security team, regardless of size, sophistication, or resources, can be empowered to defend against every attacker.

The team behind Stairwell, including security leaders and engineers from Google and Mandiant, is singularly focused on making that future a reality. Security is currently practiced as a linear process, but ideally it is circular, continuous and should always be building on itself. And, it should always start by looking at what’s most important to an organization, which is their own internal data. Good security starts with a deep understanding of the assets, software, and files inside your environment.

That’s why we start inside out.
