Red teaming has always played a role in testing defenses, but in 2026 its role is changing. Security teams are no longer asking whether an attacker can get in. That question has already been answered. The real challenge is whether teams can detect, validate, and respond before an incident escalates.

That shift sits at the center of this year’s Rapid7 Global Cybersecurity Summit, taking place on May 12-13. As part of the Continuous Threat Defense pillar, the summit will explore red teaming not as a standalone exercise, but as a core input into how modern security operations function day to day.

From validation to continuous feedback

In sessions like Using Red Teaming to Power Preemptive MDR, the focus moves away from point-in-time testing and toward becoming part of a continuous feedback loop. Detection logic is tested against real attacker techniques and gaps are exposed before they become incidents. Response workflows are refined in conditions that reflect how attacks actually unfold, rather than how they are expected to behave.

This represents a clear shift from traditional engagements. Instead of producing a static report, red teaming feeds directly into detection engineering and MDR operations. Many teams still rely on assumptions about coverage, but those assumptions often break down under pressure. Continuous validation helps close that gap.

Aligning red teaming with how attacks really happen

Modern attacks rarely follow a clean path. They move across identity, cloud, and endpoint, taking advantage of timing, visibility gaps, and delayed decisions. Red teaming has to reflect that reality.

At the summit, the conversation connects adversary behavior with how detection and response teams operate in practice. This includes how signals are correlated across environments, how escalation decisions are made, and where teams lose time during an investigation. The goal is not to simulate attacks for the sake of it, but to understand how those attacks would be detected, prioritized, and contained in a real environment.

Why red teaming matters now

The move toward preemptive security operations depends on confidence. Teams need to know that what they have built will hold up when it matters. Red teaming supports that by grounding security programs in evidence. It shows what works, highlights what does not, and gives teams an opportunity to improve before a live incident forces change.

This becomes even more important as organizations adopt MDR models, integrate AI into workflows, and operate across increasingly complex environments. Without continuous validation, complexity creates blind spots that are difficult to see until it is too late.

Rapid7's Cybersecurity Summit: A preview of what’s to come

Red teaming is one part of a broader shift happening across the summit. Sessions across detection, response, AI, and exposure management all point in the same direction: Security operations must move earlier in the attack lifecycle, reduce noise, improve prioritization, and support faster decisions with better context.

More sessions and speakers will be announced in the coming weeks, building out how this shift is being applied in practice. If you are responsible for detection, response, or validation of your security program, this is a conversation worth being part of.
