Your SOC receives 10,000 alerts today. But here is the terrifying reality security vendors won't tell you: 23% of those alerts are critical incidents that your team will completely miss. Why? Becau...

 Boaz Barzel, Field CTO at OX Security, recently conducted research with colleagues at OX Security and discovered that an average organisation had more than half a million alerts at any given time. More astonishing is that 95% to 98% of those alerts are not critical, and in many cases are not even issues that need to be addressed at all.  This deluge has resulted in the alert fatigue issue, which jeopardises the foundations of our digital defence and is firmly entrenched in neuroscience.  Security experts must constantly manage alerts. Veteran security practitioner Matt Johansen of Vulnerable U characterises the experience as follows: "You're generally clicking 'No, this is OK.'" 'No, this is OK' 99 times out of a hundred, and then, 'No, this is not OK.' And then this is going to be a very exciting and unique day."  This creates a perilous scenario in which alerts keep coming, resulting in persistent pressure. According to Johansen, many security teams are understaffed, resulting in situations in which "even big, well-funded organisations" are "stretched really thin for this frontline role.” Alert overload  As the former director of the Gonda Multidisciplinary Brain Research Centre at Israel's Bar-Ilan University and the Cognitive Neuroscience Laboratory at Harvard Medical School and Massachusetts General Hospital, Professor Moshe Bar is regarded as one of the world's foremost cognitive neuroscientists. According to Bar, alert weariness is especially pernicious since it not only lowers productivity but also radically changes how professionals operate. "When you limit the amount of resources we have," Bar notes, "it's not that we do less. We actually change the way we do things. … We become less creative. We become … exploitatory, we exploit familiar templates, familiar knowledge, and we resort to easier solutions.”  The science driving this transformation is alarming. When neurones fire frequently during sustained attention activities, they produce what Bar refers to as "metabolic waste." With little recovery time, waste builds and we are unable to effectively clean it. What was the result? Degraded cognitive function and depleted neurotransmitters such as dopamine and serotonin, which regulate our reward systems and "reward" us for various activities, not just at work but in all aspects of our lives. The path ahead Alert fatigue poses a serious threat to security efficacy and is not only an operational issue. When security personnel are overburdened, Bar cautions, "you have someone narrow like this, stressed, and opts for the easiest solutions." The individual is different.  Organisations can create more sustainable security operations that safeguard not only their digital assets but also the health and cognitive capacities of individuals who defend them by comprehending the neurological realities of human attention.

Although alert fatigue is blamed for high override rates in contemporary clinical decision support systems, the concept of alert fatigue is poorly defined. We tested hypotheses arising from two…

Alert fatigue is overwhelming SOC teams because security tools generate too many low-context alerts, making it hard to distinguish real threats from noise. The article argues that the best path forward is better correlation, enrichment, and AI-assisted automation that adds context rather than simply reducing alerts. #Lanxit #SentinelOne #ArcticWolf #Darktrace #Presidio...

MSPs are overwhelmed by fragmented security alerts that create noise, blind spots, and delayed threat detection across client environments. Unified SIEM visibility helps connect signals, reduce alert fatigue, and improve response speed while strengthening the business case for security services. #Kaseya #KaseyaSIEM

Alerts should be like smoke alarms—rare, loud, and only triggered by real danger. If your monitoring screams for burnt toast, engineers will ignore it. This ELI5 guide explains alert fatigue, actionable alerts, and why good alerting keeps systems—and humans—safe.
