What CISOs Should Expect from AI Powered MDR in 2026, According to Rapid7 CEO Corey ThomasIn the latest episode of Rapid7’s Experts on Experts, I’m joined by Rapid7 CEO Corey Thomas for a candid conversation about where AI is genuinely changing security operations, and where the hype still outruns reality. The short version is that AI is already improving productivity in software development, but the bigger shift for security leaders is what it can do with telemetry at scale. As Corey puts it, no team of humans can process all security telemetry, all the time, across an entire environment. That gap is where AI can help, but only if the inputs are right. We also dig into what this means for Managed Detection and Response (MDR), and why the market is moving from “watch a subset of signals” toward monitoring the full environment, 24 x 7. The catch is that raw volume is not the goal. The goal is a comprehensive data set that enables decision making under pressure, with enough context to act early. AI is only as good as the context behind it One theme that kept coming up in our conversation is trust. Corey explains why earlier automation and SOAR efforts struggled. They followed strict rules, but security rarely behaves in strict patterns. When something looked similar but required a different response, teams hesitated to rely on automation. The dynamic rule making that newer AI models provide can help, but only if fueled with the right context. Corey breaks “context” into practical components: understanding what technologies are deployed, how they are configured, what controls exist, what vulnerabilities are present, and what activity is actually happening across those systems. Without that full picture, teams spend time chasing the wrong risks. He compares it to buying earthquake insurance without knowing where you live. If you are in California, it might make sense. If you are in Florida, hurricane coverage is the real concern. Context tells you which risk actually matters. Preemptive MDR is the shift CISOs should plan for now Where the conversation gets especially relevant for 2026 is the move from reactive to preemptive security. To frame the change in plain terms: reactive posture waits for alerts, while leaders want partners who anticipate and identify risks earlier. Corey describes preemptive MDR as an attack surface discipline. It starts with understanding the full attack surface, spotting where attacks are likely to occur, and identifying the most attractive exposures in the environment. The operational step is what matters: identifying those exposures quickly, prioritizing realistically, and having preset remediation and response plans ready before the moment hits. Corey is direct about constraints, too. No organization can remediate everything all the time, but better planning and efficiency are still possible, and business expectations of security leaders are rising. He also notes that government and regulators are pushing in the same direction, and that Gartner and other analysts are reinforcing the shift toward anticipation
