Your Purple Team Isn't Purple - It's Just Red and Blue in the Same Room

"Defending a network at 2 am looks a lot like this: an analyst copy-pasting a hash from a PDF into a SIEM query. A red team script is being rewritten by hand so the blue team can use it. A patch waiting on a change-approval window that's longer than the exploitation window itself. Nobody in that chain is incompetent. Every human is doing their job correctly. The problem is the system, its workflows, and its messy handoffs. In contrast, the attacker's clock has nearly disappeared."

"In 2024, the mean time from a CVE being published to a working exploit was 56 days. By 2025, it had shrunk to 23 days. So far in 2026, it's sitting at roughly 10 hours across 3,532 CVE-exploit pairs from CISA KEV, VulnCheck KEV, and ExploitDB. The minor piece of good news is that the defender's clock has accelerated to run in hours. The really bad news is that the attacker's clock has leapfrogged past it and now runs in seconds. It's not even close to a fair fight."

"Purple teaming is simple in concept. Red finds the paths an attacker would take. Blue validates whether detections fire and prevention holds. They iterate. Red's output becomes blue's input. Blue's output becomes red's next input. The loop tightens your organization's posture continuously instead of once a quarter. That's the idea, and again, it's a solid one. The execution is where, sadly, it all falls apart."

"Reason 1: Human purple teaming creates too much friction. Almost nobody runs purple teaming as a real loop. The teams don't talk often enough;and when they do, people get pulled into long meetings, detailed reports, lengthy post-mortems, and family emergencies. The bottleneck is almost always human, in the most ordinary sense. Loo"

Defending networks often relies on slow, manual workflows such as copying hashes into SIEM queries, rewriting red-team scripts by hand, and waiting for change approvals longer than exploitation windows. Vulnerability exploitation speed has accelerated sharply: the time from CVE publication to working exploit fell from 56 days in 2024 to 23 days in 2025, and in 2026 is about 10 hours across thousands of CVE-exploit pairs. Defender validation has improved to hours, but attacker speed now runs in seconds. Purple teaming is presented as the correct approach because it creates an iterative loop where red identifies attacker paths, blue tests detections and prevention, and both sides feed results back to tighten posture continuously. Traditional purple teaming fails due to friction, bottlenecks, and insufficient operationalization.
