What Is the Meaning of Alert Fatigue?
Alert fatigue is when a monitoring system handles multiple unfiltered alerts that aren’t correctly tuned or false positives. In IT and cybersecurity, alert fatigue occurs from burnout analytics, leading to a diminished ability to react effectively and investigate threats and attacks.
Cyberattacks are growing more complex and frequent, which is contributing to alert fatigue. A recent alert fatigue statistics by IDC white paper report shows that cybersecurity and IT teams struggle with alert fatigue across businesses of all sizes. It was found that 30% of alerts were not investigated and wholly ignored, significantly impacting the cyber attack.
To better understand the causes of alert fatigue, here’s a table summarizing its causes and description.
| Cause of Alert Fatigue | Description |
| Excessive Alerts | High volume of alerts, including false positives and redundant alerts |
| Lack of Alert Prioritization | No differentiation between critical and non-critical alerts |
| Poorly Defined Alert Criteria | Imprecise or irrelevant alert conditions and criteria |
| Inadequate Alert Management Tools | Outdated or inefficient alert systems |
Excessive Alerts
An excessive number of alerts, including false positives and redundant alerts, can overwhelm DevOp and IT teams. When security professionals become progressively flooded and desensitized to alerts, they may assume they are false positives and ignore them, leading to a false sense of security and more critical issues.
Some of the most common activities or potential threats that cause excessive alert notifications include:
- Login attempts and attempted unauthorized access
- Suspicious network activity, including data breaches and network intrusion
- Detection of software viruses and malware
- False positive alerts
Lack of Alert Prioritization
Alerts have different levels of criticality, including high-priority level and lower-priority security incidents. Without meticulous and proper prioritization, alerts are handled equally, which makes it difficult to focus and respond to the most critical issues.
Poorly Defined Alert Criteria
Poorly defined alert criteria contribute to alert fatigue, generating excessive irrelevant or low-priority alerts. The high volume of irrelevant alerts desensitizes teams, making it difficult to differentiate between essential and trivial alerts. This situation eventually leads to slower responses and missed critical incidents.
Inadequate Alert Management Tools
Inefficient or outdated alert management tools significantly contribute to alert fatigue. That’s why IT teams find it hard to manage and respond to alerts. Modern tools with advanced features like filtering and automation can help reduce alert fatigue.

Effects of Alert Fatigue
Alert fatigue has many detrimental effects on IT operations and overall business performance. When DevOps teams are constantly flooded with alerts, their ability to respond effectively decreases, leading to more incidents and significant revenue, cost, and brand reputation consequences.
Here are the adverse effects of alert fatigue on IT operations and practices:
Decreased Responsiveness
When IT and DevOps teams are bombarded with alerts related to performance issues, system vulnerabilities, and IT-related events, it becomes harder for them to manage and organize system infrastructure.
Additionally, differentiating security-related and operational alerts becomes more challenging, leading to confusion and potential delays in critical security incident response.
Increased Risk of Incidents
Essential alerts are mostly overlooked and unnoticed when there is data fatigue, which causes increasing incidents and puts the company’s security at risk.
Successful malware attacks, for example, will not be detected due to ignored alerts. One alert fatigue example is the aforementioned IDC report, which estimated that over 5,000 employees of cybersecurity teams ignored 23% of their alerts. It led to unnoticed attacks, resulting in problematic system issues.
Reduced Team Morale
When team members are bombarded with alerts, it disrupts their workflow and reduces their ability to focus on significant tasks. Over time, this constant barrage of alerts leads to exhaustion, burnout, and frustration, ultimately affecting the team’s overall productivity and morale.
Higher Operational Costs
When cybersecurity experiences increased downtime, longer resolution times, and higher resource resolution, it increases organization costs and financial loss.
One relevant example is the Equifax data breach in 2017, which cost over $1.4 billion in operational costs. According to reports, the security team failed to act on system vulnerabilities primarily due to alert fatigue and overwhelming notifications.
You must know how to prevent alert fatigue to avoid these effects from impacting your operations.
