Portland cloud-security startup raises $6M in seed money for engineering, sales growth

A newly formed cybersecurity business in Portland has obtained $6 million of seed funding to expand development of the company's open-source solution for cloud computing.

ProwlerPro Inc. on Monday said it received the money in a financing round led by Decibel VC, a venture capital firm based in Palo Alto, Calif. With the boost, Prowler intends to expand its engineering, sales and marketing teams and make operational improvements.

Prowler provides a cloud-based security platform that relies on open-source technology. The company was launched in August by CEO Casey Rosenthal, an engineering veteran of Netflix, and Toni de la Fuente, who serves as chief technology officer.

“Prowler is redefining cloud security for the modern era, championing a shift towards systems that offer both transparency and adaptability. This is essential for security teams who need to respond swiftly and monitor their environments effectively,” Rosenthal said in a news release.

“The support from Decibel underscores the critical transition towards an open cloud security paradigm. With this backing, Prowler will further empower security professionals, granting them the autonomy they require to safeguard our digital future.”

Jon Sakoda, partner at Decibel VC, said, "In the rapidly evolving landscape of cloud security, we find ourselves at a transformative moment. Casey and Toni, with their unmatched track record in open-source security, are exactly the leaders we need to usher us into this new chapter. Their approach with Prowler isn't just forward-thinking; it's foundational for the next phase of secure, transparent cloud environments."

Prowler says its software has been downloaded more than 7 million times and is used by customers including Amazon Web Services, an Amazon Inc. subsidiary that's one of the world's largest providers of cloud computing platforms.
