In this conversation, Ryan Cribelar, R&D Engineer at Nucleus Security, breaks down why internet exposure is one of the most important layers of context in vulnerability and exposure management. Security teams are flooded with vulnerability data, but not every finding carries the same level of risk. As Ryan explains, whether a vulnerability is reachable from the internet can dramatically change how urgent it really is. Internet exposure shortens the path from discovery to exploitation and often determines whether a vulnerability is theoretical or immediately actionable.

In a joint webinar with leaders from Nucleus, Cycode, and HackerOne, HackerOne product manager Kyle Mativier explains how advancing AI capabilities are collapsing how long it takes attackers to exploit seemingly low to medium severity vulnerabilities.

Security researcher and analyst Jon Oltsik examines how some companies go too far with automation and capabilities, stressing the need for alignment between security and IT operations.

Security researcher and analyst Jon Oltsik talks about the importance of shifting lift and employing threat informed defense in this short clip.

Industry researcher and analyst Jon Oltsik explains why vulnerability management should be considered a business issue and stop being viewed as a technical issue.

In this episode of Nucleus Conversations, industry analyst and researcher Jon Oltsik unpacks the current state of exposure management, why so many organizations still struggle to manage cyber risk at scale, and the impact the recent Nucleus 3.0 releases will have for customers.

Security leaders are bracing for a pivotal shift in 2026. Attacker economics are evolving, extortion models are changing shape, and organizations are rethinking how they allocate resources to defend against more scalable and financially motivated threats. In this on-demand webinar, four industry experts break down the forces reshaping cybersecurity strategy and offer practical guidance for leaders preparing for the next wave of challenges.

Nucleus Manager of Channel Enablement and Training, Tony Ramirez, talks about his recent recognition in CRN's 100 people to know for the channel. During this conversation, he also discusses the evolving role of channel leaders in cybersecurity, the importance of continuous threat exposure management (CTEM) as a process rather than a tool, and the need for contextual understanding in vulnerability management. Tony emphasizes the significance of engaging non-security stakeholders and the opportunities for the channel to educate clients on security posture and vulnerability management.

Adam Dudley, Nucleus VP of Strategy and Alliances, provides some background on the Common Vulnerability Scoring System (CVSS) version 4.0 in this Nucleus conversation. He discusses the improvements made in the new version, the evolving role of CVSS in vulnerability management, the limitations practitioners face, and the future of scoring systems in the context of emerging technologies like AI. The conversation emphasizes the importance of context and quality inputs in effectively utilizing CVSS for risk assessment.

As AI use grows, so does its dependency on the energy grid remaining up and running. This makes the energy grid a more likely target for future attacks.
