Chief Information Security Officers are realizing, in greater numbers than ever before, that cybersecurity can no longer be viewed as a siloed technical function but instead as a core enabler of business growth, innovation, and AI adoption, according to LevelBlue’s latest Persona Spotlight: CISO.

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.

Defense evasion is one of the main reasons cyberattacks go undetected for days or weeks. Attackers avoid breaking systems now. They prefer to hide inside them. For that, they use defense evasion techniques that allow them to blend into normal activity and avoid alerts. Tools like EDR and SIEM can detect parts of an attack, but cannot provide the complete picture. This creates detection blind spots. Teams also face alert fatigue, which prevents them from recognizing real threats.

Preemptive cybersecurity defense refers to the ability to detect and disrupt fraud and account takeover attempts before credentials are misused and damage occurs. According to a 2026 analyst brief from Frost & Sullivan, most enterprise fraud and cybersecurity controls still activate too late in the attack lifecycle to prevent loss.

Security logs tell you who accessed a system, but they won’t tell you where a CSV file went after someone exported it. Files move between apps, users, and third-party vendors without anyone truly tracking where they go, who touches them, or how they’re used. And that’s a massive problem when a breach happens, when auditors come knocking, or when you’re trying to tighten internal controls.
