Here’s a breakdown of some of the major product updates from Q2 2025.

You Can't Automate What You Don't Understand: Why Context Is the Missing Link in Exposure Management

In our recent webinar featuring Enterprise Strategy Group Principal Analyst, Tyler Shields, we discussed the widening gap between vulnerabilities organizations know about and what they can realistically fix. Most teams are swamped. Too much data, too many tools, and not enough people. Naturally, automation and AI come up as potential solutions. One comment from Tyler has stuck with me since watching and subsequently reviewing the webinar recording.

Why Threat Exposure Management Is Broken - And What Needs to Change | ESG + Nucleus Security

Security teams today aren’t struggling to find issues; they’re struggling to reduce risk in a measurable, scalable way. In this webinar, ESG Principal Analyst Tyler Shields joins Nucleus Security to unpack brand-new research on the state of threat and exposure management (TEM).

Why 'Vulnerability Management' Was Always the Wrong Name for the Job

Let’s get this out of the way: the term vulnerability management has always been misleading. It evokes the idea that we’re wrangling a tidy list of software flaws, checking boxes, patching holes, and keeping things humming. But anyone who’s worked in the trenches or tried to explain this chaos to an executive board knows the truth. What we call “vulnerability management” isn’t a single discipline, or even a well-contained function.

Nucleus MCP Integration: Scaling Risk Reduction with AI-Driven Insights

Today, we’re excited to announce a preview of the Model Context Protocol (MCP) Server for Nucleus. This marks an important step towards AI-native workflows for vulnerability and exposure management. Model Context Protocol (MCP) is an emerging industry standard enabling seamless integration between enterprise applications and AI models. Backed by leading organizations like OpenAI, Microsoft, and Google, MCP servers are quickly becoming the foundation for AI-enablement across the enterprise.

Best Practices for Aggregating and Normalizing Exposure Data

In our first article exploring vulnerability management vs. exposure management, we explored the growing recognition that exposure management is not just a rebranding of vulnerability management. Rather, it’s a strategic evolution. Where traditional vulnerability management often focuses narrowly on CVEs and technical severity, exposure management demands a broader, more integrated understanding of risk across assets, environments, and attack vectors.
