Most teams run on velocity budgets, not risk budgets. While features get sprints, milestones, and release slots, risk, on the other hand, gets hope. When scan depth and speed decisions are made without an explicit budget for risk, the outcome is predictable: throughput is optimized while exposure compounds silently in the background.

Software delivery today is a delicate balancing act between moving quickly and maintaining security. CXOs chase release velocity, PMs measure success by the number of features shipped, and developers are asked to code faster with every sprint. However, every pipeline that prioritizes speed without embedded security is essentially gambling with the risk of a breach. Legacy security models still act like toll gates, piling on reviews and post-deploy scans that stall progress.

In Part 1 of this blog series, we explored the architecture, capabilities, and risks of the Model Context Protocol (MCP). In this post, we will focus on two attack vectors in the MCP ecosystem: prompt injection via tool definitions and cross-server tool shadowing. Both exploit how LLMs trust and internalize tool metadata and responses, allowing attackers to embed hidden instructions or persistently influence future tool calls without direct user prompts.

Today we’re announcing the beginning of the next phase of our journey. We’re launching our Vulnerability Intelligence feed, Nucleus Insights. As we’ve worked with many companies, partners, and clients over the years, this became an obvious next step for Nucleus, and I want to share with you why. Fixing vulnerabilities is expensive. Not just in terms of patching costs or system downtime, but in people, time, and lost focus.

As IT environments become more complex, organizations face rising threat volumes, persistent cybersecurity talent shortages, and adversaries capable of dwelling undetected for days and moving laterally within hours. In this context, choosing between SIEM and XDR is no longer a technical preference; it’s a strategic decision that shapes how your organization defends itself.

Jury duty scams are on the rise. Learn how to recognize the red flags, protect your personal data, and verify real court notices. “You missed jury duty and there’s a warrant out for your arrest.” If you've received a call like this, take a breath. Odds are, it's not the court—it’s a scam. These jury duty scams are making the rounds again, and they’re catching people off guard.
