Building Open Cloud Security for the Long Haul

Today we’re sharing an exciting milestone for Prowler and the open cloud security community: we’ve raised an additional $6.5 million in seed-extension financing, bringing our total seed round to $12.5 million. This round was led by Decibel VC, with participation from SNR, IrregEx, and several angel investors who deeply understand what’s needed to secure the cloud — and believe in the future we’re building together.

This funding allows us to continue doing what we’ve always done: build in the open, serve our users, and push cloud security forward — not by locking things down, but by opening them up.

Why Open Cloud Security?

The cloud is not getting simpler. As organizations move faster, adopt more services, and connect more dots, the need for adaptable, programmable, and community-driven security is more urgent than ever.

Security should not be a black box. It should not require a procurement process to see how it works. It should not be siloed from the people it’s meant to protect.

That’s why we created Prowler. And that’s why we’re betting everything on open.

What This Means for Prowler

Since our founding, we’ve stayed focused on three principles:

• Build for practitioners — the people in the trenches, not just the buyers in the boardroom.
  
• Stay transparent — in our code, our roadmap, and our values.
  
• Work with the community — not just as users, but as contributors and co-creators.

This funding enables us to go further, faster. With it, we’ll accelerate multi-cloud coverage, improve extensibility and automation, and support more integrations with the tools security and DevOps teams already rely on. We’ll also be investing in the community — from documentation and education to our contributor experience and our upcoming Open Cloud Security Conference.

What’s Next

At AWS re:Invent, we launched Prowler 5 — our biggest release yet, with unified multi-cloud support and continuous security assessments across AWS, Azure, GCP, and Kubernetes. Since then, we’ve shipped multiple updates (hello, Prowler 5.4) and doubled down on enabling practitioners to secure complex cloud environments in simple, powerful ways.

On April 8, we’ll host the first Open Cloud Security Conference, where we’ll gather voices from across the industry — engineers, CISOs, researchers, and open source maintainers — to talk about where cloud security is going, and how we build it together.

We are grateful to our new and existing investors, our community of contributors, and our early customers who have believed in us, challenged us, and helped us grow. You are the reason we’re here and the reason we will keep pushing forward.

We’re Just Getting Started

Open cloud security is not a slogan. It’s a movement. It’s a commitment to building tools that are transparent, extensible, and usable by anyone, anywhere. That’s what the cloud demands. And it’s what we believe in.

We’re hiring. We’re building. And we’re listening.

Thanks for being part of this journey.
