Why do we need anomaly detection?

Anomaly detection is imperitive for businesses in order to identify potential issues that can impact revenue, customer experience, application performance and more.

Which method is best for anomaly detection?

<span data-sheets-value="{"1":2,"2":"Automated anomaly detection is the fastest and most accurate mothod of anomaly detection. Unlike manual detection of anomalies, which relies on a large team of data analysts, automated systems can monitor an unlimited amount of metrics and provide real-time, accurate insights into anomalies.

What are the challenges in anomaly detection?

<span data-sheets-value="{"1":2,"2":"The challenges of anomaly detection include the ability to detect abnormal behavior in massive data sets if monitoring manually. If an organization is building an automated anomaly detection system, the challenges include the time and resources needed, the complexity of learning normal behavior and data quality issues.
