A sophisticated cyberattack can last for weeks, even months without being detected, according to cybersecurity company Stairwell. The Mountain View-based company secured $45 million in Series B funding to help organizations stay ahead of these bad actors with its automated analytics solution. 

The company’s latest funding round was led by Section 32 and will go toward building out its Inception product. This tool works to offer actionable visibility into a company’s digital environment, enabling security team members to detect and respond quickly to current, future or past attacker compromises. Several Fortune 500 companies use the solution, according to release from Stairwell.

“New vulnerabilities are discovered daily, and continuous monitoring, threat hunting and response are needed for around-the-clock efforts to secure the enterprise,” Mike Wiacek, CEO and founder of Stairwell, said in a statement. “Our goal is to plug these gaps, while simultaneously strengthening organizations’ overall security stack via capturing, storing and analyzing all executable files across their environment.”

Amid a continual rise in malware attacks, Stairwell is responding to increased demand for new features to its Inception product. Its new capital will help scale the platform and provide clients with additional capabilities for securing their organizations against malware threats, such as supply chain attacks.

Stairwell also plans to invest in growing its team, building on past momentum. When recently growing its headcount by 100 percent, Stairwell brought on Brian Lee, formerly of Ogilvy, as VP of marketing and Eric Byrd, from Red Canary, as head of enterprise sales.

Looking ahead, the company is currently hiring for a handful of engineering roles as well as a field marketing and events manager. The Series B raise brings Stairwell’s total funding to date to $69.5 million.
