Data Deluge Becomes Primary Obstacle for Cyber Threat Hunters, SANS Report Shows

According to a recent study by the SANS Institute, the most pressing difficulty faced by cyber threat hunters is no longer a shortage of skilled personnel but an overwhelming volume of data that must be sifted to uncover malicious activity.

The findings, highlighted in Infosecurity Magazine, indicate a shift in the threat‑hunting landscape where the sheer amount of log files, telemetry and cloud‑generated alerts is outpacing the ability of analysts to process it efficiently. Researchers surveyed professionals involved in active threat‑hunting operations and found that data overload consistently ranked above traditional skill gaps.

Historically, organizations have invested heavily in training programs to address a perceived deficit of expertise in identifying and responding to advanced threats. While talent remains essential, the SANS study suggests that even well‑trained hunters are hampered by the exponential growth of information produced by modern IT environments, including Internet‑of‑Things devices, multi‑cloud deployments and continuous integration pipelines.

Experts note that the challenge is twofold: first, the need to collect and retain massive datasets for retrospective analysis; second, the difficulty of extracting actionable insights from noisy, heterogeneous sources. Without effective data‑management strategies, critical indicators of compromise can be buried beneath benign traffic, increasing dwell time for attackers.

The report recommends that security teams prioritize investments in data‑centric solutions such as advanced security information and event management (SIEM) platforms, automated analytics, and machine‑learning‑driven threat detection. By augmenting human expertise with tools that can normalize, correlate and prioritize alerts, organizations can alleviate the bottleneck created by data volume.

Looking ahead, the SANS Institute suggests that the industry’s focus will likely move toward building robust data pipelines and fostering cross‑functional collaboration between threat hunters, data engineers and incident responders. As the data landscape continues to expand, the ability to efficiently navigate and interpret it may become the defining factor in successful cyber defense.
