AI is changing that resource equation — and giving security teams a way to measure and close coverage gaps that most programs have never been able to quantify. - Author: George V. Hulme - Tags: AI Detection Engineering, Detection Engineering, Security Automation, Article For three decades, detection has been a broken promise in security. Organizations have spent billions on tools, analysts, and processes built on the assumption that if something malicious happens in their environment, they can and will see it. However, most won't. The detection stacks most enterprises run today were not designed to measure their coverage; they were designed to generate alerts. A system optimized for alert volume with no agreed metric for what proportion of actual attacker behavior it catches is not a detection program. It is a noise machine. The lack of effective and efficient detection capability has been a drum Sima has been beating. Caleb Sima, founding general partner at Whiterabbit and founder and chair of the CSA AI Security Alliance, contends the more fundamental problem lies in the detection logic (the rules, queries, and behavioral signatures that tell a security system what to look for) enterprises use. "Organizations are at a place where they are always late to detect," Sima said. "They’re not doing early detection; they’re generally finding out they’ve been breached after the fact. That’s largely because they’re dealing with an overload of false positives, a lack of coverage, and a lack of capability." [Subscribe to the CYBR.SEC.Media newsletter](#/portal/signup/free) In practice, detection engineering automation continuously interrogates the detection stack: identifying which attacker behaviors current rules would catch, which would slip through, and what new or modified logic would close the gap. Rather than waiting for an alert to process, it reasons proactively: given what is known about how attackers move through an environment, what should the detection stack be looking for that it currently isn’t? Detection engineering builds and tunes rules, retires logic that generates noise without signal, and maps coverage against known threat behaviors. Detection engineering as a discipline has historically been expensive, slow, and dependent on scarce senior talent. Writing a high-fidelity detection rule requires deep knowledge of attacker tradecraft, intimate familiarity with the environment's data sources and logging behavior, and enough experience to anticipate the false-positive conditions that make a rule unusable in production. Most organizations have a handful of people who can do that work well, and those people spend most of their time maintaining existing rules that drift as the environment changes, leaving little capacity to close new coverage gaps as threat actor techniques evolve. Automating detection engineering changes that equation. An AI detection engineering system can continuously map the organization's current detection coverage against known threat behavior frameworks like MITRE ATT&CK, which provide the structured catalog of attacker techniques that makes this mapping tractable, identify which techniques the current stack would catch and which it would miss, draft new detection logic to close specific gaps, and test proposed rules against historical data before they reach production. Work that previously took a senior detection engineer days now runs continuously in the background. The practical benefit is not just speed. It is coverage visibility: for the first time, security teams can answer what proportion of attacker behavior their stack would actually detect and show how that number changes over time. The instinct within many teams is to focus on false negatives, the threats that slip through. Sima says this is the wrong priority for most organizations. "Organizations can't catch basic stuff today," he said. "So they should not be worried about catching the zero-day attacker, or catching advanced attacks. What you need to worry about right now is knowing whether or not they even have the ability to catch a basic or intermediate threat actor." Beyond less-than-optimal detection capabilities, most organizations still don’t know what they’re protecting. Benjamin Spencer, product director at cybersecurity services provider Optiv, says most organizations don’t understand their environment because they never completed basic asset management, formally mapped which assets connect to what, or established what normal looks like well enough to know when something has deviated. Without that foundation, the question of what the detection stack is missing is not just unanswered: it is not answerable. Without a clear metric for detection coverage, security programs can't know where their gaps are, can’t prioritize detection engineering investment, and can’t make a credible business argument that they’re improving their detection capabilities. And if a security team can’t demonstrate that AI SOC tooling measurably improved detection coverage during a pilot, the business case for moving to production doesn’t exist. Detection engineering automation addresses that problem directly: not by generating more alerts from existing logic, but by giving security teams the ability to measure and improve the probability of detecting an actual attacker and to show that improvement in terms a budget conversation can support.
