Why Your Threat Hunting Program Might Be Failing

CISOs and security operations center (SOC) teams worldwide face growing uncertainty at the leadership level and widespread fatigue among analysts. Burnout is at an all-time high (84% of cybersecurity professionals report experiencing it), yet many teams still struggle to determine whether they’re detecting the threats that pose the most risk. When asked about insider threats or subtle shifts in behavior, many leaders can’t say with confidence whether their tools can catch them.

This blog explores why conventional detection methods continue to fall short and how a modern, programmatic approach to threat hunting can help uncover hidden activity and strengthen organizational security. If you’re relying solely on rule-based alerts or legacy workflows, it’s time to take a closer look.

When Threats Don’t Look Like Threats

Not every breach begins with a brute force attack or a suspicious domain. Sometimes it’s a trusted employee innocently plugging in a USB drive, a contractor using valid credentials to access sensitive data, or a seemingly harmless VPN session that hides something far more dangerous.

Many of today’s most damaging threats are subtle and slow moving. They often involve compromised credentials or insider activity and mimic legitimate user behavior, making them difficult to detect. These threats operate from within, blending in with normal activity. This is why more security teams must evaluate how they approach threat hunting. If your tools are only built to detect known indicators of compromise (IoCs) and catch obvious attacks, chances are you are missing the real threats.

Why Conventional Threat Hunting Falls Short

Many SOCs still depend on rules, signatures, and basic IoCs to detect threats. These methods work for known attacks but often miss stealthier tactics, especially when adversaries use valid credentials or move laterally without triggering obvious alerts. That’s why firms like Gartner now recommend identity-based security and behavioral anomaly detection.

The issue goes beyond the volume of data. It stems from a lack of meaningful context. Isolated artifacts such as IP addresses or file hashes change frequently and offer limited insight into how a threat behaves once inside the network. Analysts end up chasing alerts that may not reflect actual risk.

More importantly, behavior-based anomalies such as unexpected access to sensitive systems or inconsistent login activity often go unnoticed. These signals do not fit into predefined rules, which makes them easy to miss even when they signal something serious.

This creates a false sense of security. Teams often assume their detections are working until it is too late. By focusing on what is easy to detect, they miss subtle patterns that signal real threats. As environments become more complex and attackers adapt, these visibility gaps continue to expand.

Exabeam supports this shift with machine-learned threat detection and contextual enrichment that identify behavior-based anomalies in real time. By moving beyond static correlation rules, analysts can detect subtle, high-risk activity as it unfolds, gaining the visibility they need to stop threats that traditional tools often miss.

The Shift to Programmatic Threat Hunting

As threats grow more subtle and compromised credentials remain the attacker’s favorite tool, security teams are realizing that ad hoc detection is no longer enough. A missed login anomaly here or a quiet data transfer there can snowball into a major breach. What is needed now is a more structured approach to threat hunting that focuses on behavior, not just artifacts.

Programmatic threat hunting is about making threat detection repeatable, consistent, and tied to real patterns of attacker behavior. Instead of reacting to alerts as they come in, analysts follow defined processes to proactively search for suspicious activity based on tactics and techniques rather than just known indicators.

This approach requires more than just tooling. It depends on context, collaboration across teams, and a clear understanding of what normal looks like in your environment. When done right, it helps uncover threats that would otherwise remain hidden and gives analysts the context and structure they need to investigate efficiently and respond quickly and accurately.

Exabeam operationalizes this approach through workflows that combine risk scoring, visual timelines, and MITRE ATT&CK^® mapped detections to guide investigations. With Exabeam Nova, a coordinated system of six AI agents designed just for the SOC, behavior-based anomalies are surfaced automatically. And the Outcomes Navigator app aligns detection coverage to 21 use cases and ATT&CK threat techniques. These capabilities enable proactive threat hunting and help leaders track progress, close gaps, and strengthen their detection coverage over time.

A Better Way Forward

Modern threat actors do not follow simple, linear playbooks. They adapt quickly, hide in plain sight, and take advantage of blind spots across the environment. To keep up, security teams need a better strategy—one that goes beyond reactive alerts and surface-level indicators.

Leading organizations align their threat hunting efforts with frameworks like ATT&CK. Instead of just chasing individual artifacts, they are looking for tactics and techniques that reveal how an attacker thinks and moves. This shift gives analysts the ability to track behavior across the full kill chain, not just at the point of compromise.

Exabeam Nova turns this strategy into tangible results with automatically generated ATT&CK coverage summaries that show where your detection is strong and where gaps remain. These insights help CISOs and analysts prioritize improvements and demonstrate measurable progress. Threat Center adds to this by stitching together attack sequences into automated timelines and offering built-in case management, so investigations stay focused and organized throughout the entire workflow.

It also means investing in user and entity behavior analytics (UEBA), where context becomes the key to separating noise from real risk. When you understand how a user typically behaves, it becomes easier to spot when something is off, even if the credentials look valid.

If your SOC still relies on basic correlation rules and scattered detection tools, it may be time to ask whether your current approach is designed for the threats you face.

If your team is spending more time reacting than detecting, you are not alone. Many SOCs are built around legacy models that were never designed to handle today’s complex, identity-driven threats. But that can change.
