Alert fatigue and its impact on SOC efficiency are clear issues. However, the underlying causes, consequences, and potential solutions are far more nuanced and challenging to address.
Security Operations Center (SOC) analysts face an overwhelming and constant stream of alerts from various security tools. On their own, most alerts lack meaningful significance unless they can be linked to other related events. Yet, identifying these connections is a laborious process—and even when correlations are found, they may have little bearing on actual business security. The majority of alerts are essentially background noise, but sifting through this flood to isolate genuine threats (signals) from false alarms (noise) is tedious, monotonous, and frequently unproductive.
Several factors contribute to this challenge:
Lack of automated prioritization. While security tools excel at detecting potential threats, they fall short when it comes to ranking them by importance. Alerts sometimes include a severity score—“A tool might report, ‘I’ve detected a threat with a score of 32 out of 100,’” explains Obbe Knoop, founder and CEO of Lanxit. “But what does that really mean? What would a perfect 100 look like? Why assign a 32? Without proper context, such scores are essentially meaningless.”
Insufficient alert context. Alerts often lack—or entirely miss—the contextual information needed to assess their true urgency. For instance, an alert might flag a critical vulnerability, yet further context could reveal that the affected device has no external network access and poses zero risk to business operations. In such cases, the alert can be safely deprioritized. Accurate, comprehensive context is essential to determine real-world relevance.
Jeff Reed, CTO at SentinelOne, puts it succinctly: “Alert fatigue isn’t really about how many alerts there are—it’s about how relevant those alerts actually are.”
Cybercriminals’ growing use of AI is accelerating the speed, complexity, and stealth of attacks. “Attackers are leveraging AI to scale their efforts—processing stolen data more quickly, crafting highly convincing phishing emails, and automating stages of their intrusion workflows,” notes Reed. This trend directly fuels the ever-increasing volume of security alerts.
Defensive adoption of AI also expands the attack surface available to adversaries. “AI systems themselves are now part of the threat landscape, creating new vulnerabilities related to model tampering, data leaks, and misuse—which in turn generate even more alerts,” Reed adds.
“Ultimately,” he emphasizes, “human analysts simply can’t keep up with the pace at which modern environments produce security signals.”
This creates two major problems. First, analysts endure relentless pressure and chronic stress. Second, leaving the role may not be feasible due to personal obligations—like family commitments or financial responsibilities such as a mortgage. This environment is a breeding ground for burnout.
In short, today’s SOC analysts face a dual threat: alert fatigue (which undermines job performance) and burnout (which harms both professional effectiveness and personal well-being)—ultimately weakening the organization’s overall security posture.
Effects
Burnout isn’t a medical condition—it can’t be “cured,” only prevented or mitigated. One option is switching jobs, but that means the company loses a highly skilled professional. Prevention is far more effective than remediation—and it also helps reduce or eliminate alert fatigue altogether.
Alert fatigue doesn’t stem from occasional spikes in workload or stress; it results from unrelenting, high-pressure conditions with no relief in sight. If left unaddressed, it can start with analysts missing a few false negatives and escalate into a full-scale security breach.
For the individual analyst, it may begin with subconscious, overly aggressive filtering—just to stay ahead of the incoming alert deluge. During this process, too many alerts get dismissed as false positives. While most may indeed be noise, some could be real threats mistakenly ignored.
The fix must come from the organization—not from overburdened analysts. Without systemic changes, the noise will only grow, worsening both the causes and effects of alert fatigue.
Left unchecked, alert fatigue can turn a strong security defense into a hidden liability—leading to delayed threat containment, longer attacker dwell time, and a broader impact across the organization.
Solutions
Two primary strategies can help prevent alert fatigue: either reduce alert volume through smarter filtering to improve the signal-to-noise ratio, or enhance triage speed and accuracy using AI-driven automation. However, aggressive filtering risks discarding real threats along with the noise, while current AI solutions aren’t yet infallible.
Ariel Parnes, former colonel in the IDF’s 8200 Cyber Unit and now co-founder and COO of Mitiga, proposes a different approach: instead of reducing alerts, increase their visibility—but intelligently correlate and surface related ones for analysts. The aim is to reconstruct every action, log, and signal into a coherent attack narrative, so analysts aren’t reviewing isolated incidents but instead interpreting a complete, decoded story of adversary behavior.
“AI-native automation,” he suggests, “can transform overwhelming alert floods into clear priorities—automating initial triage and speeding up investigations so the SOC leads the response rather than constantly reacting to it.”
Ismael Valenzuela, VP of Threat Intelligence at Arctic Wolf, supports this vision, emphasizing that automation should free analysts to focus on deep threat investigation rather than repetitive, manual alert sorting.
“Organizations are shifting toward integrated operational models that combine automation, event correlation, and continuous monitoring—to cut through the noise, improve prioritization, and give analysts room to address both sides of the equation.”
Reed concurs: “Routine tasks like log analysis, data enrichment, and preliminary investigations can be automated, enabling analysts to concentrate on understanding attacker tactics and making high-level strategic decisions. When machines handle the heavy lifting of data processing,” he adds, “security teams gain the clarity and bandwidth needed to respond effectively.”
His recommendation centers on leveraging artificial intelligence for automation: “AI is becoming indispensable for analyzing vast amounts of telemetry, correlating signals across diverse environments, and pinpointing the tiny fraction of events that represent genuine risk. Instead of bombarding analysts with thousands of disconnected alerts, AI can cluster related activities, enrich them with context, and rank incidents based on potential business impact.”
Michael Brown, Field CISO at Presidio, adds: “Analysts should never work directly on raw alerts—only on correlated, contextualized incidents. This dramatically accelerates investigation and remediation while reducing staff burnout and turnover.”
The real question is, ‘How do we make this happen?’ Not every AI system performs at the same level. AI is limited to what it has been trained on. It doesn’t recognize the gaps in its knowledge – yet it might still generate an incorrect answer to fill those gaps.
Merlin Gillespie, CTO of Cybanetix, proposes a different strategy. He argues that relying primarily on known indicators of compromise (IoCs) is no longer enough. “Attacks have grown much more sophisticated over the past few years. Adversaries are now gaining access through stolen credentials and maintaining persistence using ‘living off the land’ methods, which makes detection far more challenging.”
Supporting Parnes’s viewpoint, he adds, “We need to gather more alerts, not fewer, to catch and piece together those subtle indicators. Collecting more alerts and adopting a defensive mindset allows these attacks to be detected sooner. But this naturally increases the risk of alert fatigue and analyst burnout. That’s exactly why we need technology to handle the heavy work.”
His recommended approach combines machine learning (ML) with large language models (LLMs). “Used together, they can manage about 90% of alert triage and investigation. ML can analyze enormous datasets and detect patterns, anomalies, and potential breaches. Over time, even make predictions about future attacks and enhance detection capabilities,” he explains.
“LLMs, meanwhile, can clarify alerts, summarize investigation findings, and generate case reports – accelerating the investigation process and delivering easy-to-read outputs.”
However, he cautions that AI still has significant limitations. “Its subjective nature makes it prone to inconsistency. In a recent experiment, we observed an agent that not only mischaracterized the threat but also invented an entirely fabricated kill chain. This shows,” he notes, “that AI hasn’t yet reached the level of maturity required.”
The answer seems to come down to context. While everyone agrees that alert context is essential for accurate correlation and prioritization, there’s little consensus on what context actually entails or how to obtain it.
Valenzuela ties it to deviations from the norm. “Effective noise reduction requires… identifying which assets are genuinely at risk and defining what normal versus abnormal activity looks like in their specific environment,” he says.
“Simply layering on more tools without that understanding tends to increase complexity and alert volume rather than improve results – creating what many refer to as an ‘all noise, no signal’ problem.”
He emphasizes that the focus should be: “Improving signal quality by adding context to alerts and continuously updating detection logic to reflect an evolving environment, rather than depending on fixed, static rules.”
Rob Demain, CEO of e2e-assure, believes that once AI handles the routine analysis, context becomes clear to the analyst. “AI takes over the repetitive tasks that consume so much of an analyst’s time. The outcome is faster, more consistent initial responses, and a team that can focus their energy where it counts most: grasping context, refining threat intelligence, and making the nuanced decisions that no machine can replicate.”
Gillespie sees the LLM component of an ML and generative AI combination as the key to uncovering context. Reed agrees: “AI can cluster related activities, provide context, and rank incidents based on probable impact.”
Toby Lewis, global head of threat analysis at Darktrace, shares the same view. He acknowledges that manually extracting context from the noise is an enormous challenge. “Constructing a tech stack that integrates these data feeds without massive manual effort seems almost impossible – but AI makes it far more achievable. Its ability to combine, correlate, and analyze data in real time creates a unified picture.”
Brown offers a more detailed explanation. “Mature SOCs automatically enrich their raw alert data so that analysts begin investigations with context already in place. This enrichment might include asset inventory details, asset criticality ratings, identity privileges, device ownership and physical location, historical behavior analytics, network traffic context, and much more.”
“Correlation and contextualization allow analysts to see entire attack chains rather than isolated alerts. Signals from multiple sources – endpoints, cloud logs, IAM systems, network device telemetry, and more – are linked together to build an incident narrative and help analysts grasp the full picture far more quickly.”
Having complete context helps pinpoint the genuine positive alert amid the noise. It clarifies what demands immediate action and what can be deferred.
Knoop illustrates why this context matters. “You might receive an alert about a vulnerability on a machine. The vulnerability is scored 100 out of 100 – extremely critical – so it seems like an emergency. The analyst panics.”
But, as Knoop points out, “When you examine the full context, you might discover that the machine is in a lab somewhere, with no connection to any business data. So even if something does happen, the revenue impact – the operational impact – on the business could be zero. Yet current tools don’t reason holistically across all available context and ongoing activity.”
While artificial intelligence is a powerful new capability, it can also be a risky one. AI knows only what it has been taught. If it doesn’t have the right answer, it may fabricate one to cover the gap. And the people relying on AI – in this case, overworked and stressed SOC analysts – might not catch the error.
“AI is used to filter alerts,” Knoop warns, “and separately used to automate responses. But it operates without full context, and lacking full context, it can lead to wrong decisions and incorrect actions.”
In his view, context is critical to properly understanding and responding to alerts, but today’s approach to context is generally too narrow. To fully determine whether an alert is truly important or just background noise, context must be built from a deep understanding of the entire business. He believes context needs to be elevated to a new tier – or as he puts it, a new layer – which he calls ‘the reasoning layer.’ Over the past five years, he has been building such a reasoning layer at Lanxit, loosely categorized under the emerging discipline of security decision intelligence (SDI).
This reasoning layer must comprehend the business as a whole. For IT assets, it leverages the company’s CMDB. It doesn’t just register each device – it understands what data that device processes, which other devices it connects to, and the potential blast radius should that device be compromised.
This advanced reasoning layer also understands the company’s industry sector; it grasps what an adversary might be after; it uses threat intelligence to stay informed about current threats targeting that sector. It has the potential to understand every aspect of the organization – for instance, which departments may be understaffed, and even identify potential blind spots that today’s security tools can’t detect.
“It’s a system that can reason contextually across all the signals currently available – a
A new security layer operates above your existing tools, gathering and analyzing alerts to provide smarter decisions,” Knoop explains.
“When a security product flags an issue, this reasoning layer analyzes it, considering the affected machine’s details from your asset database, comparing it with industry-specific threats and business impacts,” he says. “Is this a financial institution? An auto manufacturer? A chemical producer? What threats are common in their sector?”
With all context gathered, the reasoning layer delivers a clear recommendation to the security analyst, rather than just a priority score, suggesting the appropriate next steps.
“It might say, ‘This is a problem, but the device is isolated, so monitor it and patch soon.’ Or it might urge, ‘Act now—this could cause serious financial damage,’” Knoop adds.
Knoop’s system, which is currently in beta testing, aims to tackle alert fatigue through a context-driven, advisory approach, offering a fresh strategy compared to the current incremental improvements.
As the volume of security alerts continues to rise, finding effective relief for overloaded security teams is becoming ever more critical.
