Today, we announced our Series C funding. I want to start by saying thank you to Delta-v Capital and Arthur Ventures for their partnership and conviction in what we’re building. We’re grateful for their support and for the trust they’ve placed in our team. They didn’t invest because Nucleus tells a good story.

When vulnerability remediation succeeds at enterprise scale, it’s very rarely because the vulnerability management team is finding more vulnerabilities. It’s because the program was built around the idea of turning messy findings into steady, measurable risk reduction. That’s not an easy task. It’s easier to make it a numbers game, pointing to vulnerability volumes and how many findings were addressed, rather than accurately depicting how much real risk was eliminated.

Most large organizations rely on multiple vulnerability and exposure scanning tools out of necessity. Infrastructure scanners, cloud security platforms, application security testing tools, container scanners, and attack surface management solutions all play a role. Each one is designed to answer a specific question. But when it comes to understanding the risk of the vulnerabilities and exposures they detect, each tool has its own approach to quantifying it.

For years, the cybersecurity industry has told itself that vulnerability management has been improving. This story is centered around “more”: more scanners, more data, more dashboards. Despite this abundance, by 2025 the gap between activity and outcomes became impossible to ignore. Security teams were doing more work than ever but struggled to show that risk was actually going down.

Cybersecurity in 2026 will be driven by economics. Not hype. Not novelty. Economics. Attackers follow financial incentives and scale their operations faster than most enterprises can defend. CISOs must shift from reporting technical metrics to explaining business impact, guide safe AI adoption as Shadow AI grows, and design programs that emphasize resilience over perfection.

When Kenna launched more than a decade ago, it reshaped an industry that had grown numb to vulnerability overload. Back then, vulnerability management meant looking at mountains of CSV files, scanner reports, and a never-ending backlog of unprioritized issues. Kenna introduced the idea that risk instead of raw counts should determine what gets fixed first. For many security teams, it was the first time they realized they didn’t have a vulnerability problem.

Many organizations set remediation SLAs, but static severity-based timelines and manual tracking prevent them from meeting those deadlines in a way that meaningfully reduces risk. This article outlines how automated, risk-based SLAs connect timelines to real exploitability, exposure, and asset value, turning deadlines into reliable, measurable outcomes. Key takeaways from this article.

For nearly a decade, we’ve been building Nucleus with a clear mission: to help security teams make faster, smarter, and more business-aligned decisions about what to fix first. When we started, the world called it vulnerability management. Today, the industry calls it exposure assessment. To us, that evolution isn’t just semantics, t’s the culmination of years spent redefining how organizations understand and reduce risk.

We’re proud to share that Nucleus Security has been named a Challenger in the inaugural 2025 Gartner Magic Quadrant for Exposure Assessment Platforms (EAPs) — recognized for our completeness of vision and ability to execute. This marks a significant milestone not only for Nucleus, but for the evolution of our entire industry. For the first time, Gartner has formally recognized Exposure Assessment Platforms as a distinct category.

Building an exposure management program is just the beginning of a long journey. True success comes from scaling that program through continuous optimization, measurable progress, and organizational alignment. As enterprises expand their digital footprint, exposure management must evolve from reactive vulnerability remediation to a proactive, data-driven discipline that continuously strengthens resilience.
