Out of band and invisible: How Stairwell stays one step ahead of attackers

Traditional security tools, while effective to a degree, share a critical flaw: they can be reverse-engineered. Once an attacker understands how a defense system operates, they can devise ways to bypass it, leaving organizations vulnerable. This cat-and-mouse game has defined the cybersecurity industry for years, with defenders constantly playing catch-up.

But what if there was a way to break this cycle? What if you could deploy a security solution that attackers couldn’t see, couldn’t reverse-engineer, and therefore couldn’t bypass with near certainty? This is where Stairwell’s out-of-band architecture comes into play.

The power of out-of-band architecture

Stairwell’s platform is built on a unique out-of-band architecture, unlike traditional security tools that interact directly with network traffic and applications. Instead, Stairwell discreetly collects and securely stores every executable file in a protected cloud vault, preventing attackers from wiping their tracks or viewing analysis results. This approach enables continuous, in-depth analysis of all files without exposing your security operations.
By operating out of band, Stairwell remains completely hidden from attackers, who can’t adapt to defenses they can’t detect. This stealth advantage prevents adversaries from reverse-engineering or manipulating the security system, providing defenders with a powerful, resilient edge.

Continuous rescanning: Security that evolves

The traditional security model is inherently reactive, often identifying threats only after they’ve already breached defenses. Stairwell alters this paradigm by enabling continuous rescanning of all files, even if they’ve been deemed safe. As new threat intelligence emerges, we reevaluate every file ever collected, ensuring that nothing slips through the cracks.

This proactive approach ensures that organizations are not just protected against known threats, but also against those that are yet to be discovered. It’s a security posture that evolves in real time, adapting to the latest intelligence without waiting for the next breach to occur.

The invisible advantage

Visibility is crucial — but only for defenders. Attackers thrive on understanding and manipulating the tools arrayed against them. Stairwell denies them this advantage by remaining invisible, out of band, and out of reach. Our architecture isn’t just about defending against the threats you know — it’s about staying ahead of the threats you don’t.

At Stairwell, we believe that true security means ensuring nothing escapes detection, even against the unknown. By operating out of band and remaining invisible to attackers, we keep our customers one step ahead — always. We’re your silent, invisible partner, relentlessly protecting your enterprise from every angle. With us, security is not just about reacting to threats — it’s about proactively positioning against them before they come knocking.
