SOC Insider Threat Security Analytics
UEBA has been growing for some time, and a 2022 Market Data Forecast report predicts its global market size to grow from $890.7 million in 2019 to $1.1 billion by 2025. User and Entity Behavior Analytics (UEBA) tools are critical to any organization’s cybersecurity framework. UEBA tools empower companies with the capability to detect suspicious activities, identify potential threats, and mitigate security risks effectively. This article delves into the nuts and bolts of UEBA tools, their features, benefits, and how to select the right UEBA tool for your organization.
UEBA tools are robust software systems that leverage data science, machine learning and statistical methodologies to continuously monitor user and non-user entities activity and behavior that deviates from normal (or baseline) behavior to identify anomalies that occur over a network. UEBA tools have been a game-changer in the cybersecurity landscape, bringing some of the earliest implementations of artificial intelligence (AI) into security operations.
These tools operate by analyzing and learning from historical data, crafting a baseline of standard behavior. This baseline is then used to detect deviations or anomalies that could indicate potential security threats. In this regard, UEBA tools deliver an “early warning” that identifies potential risks as an attack campaign is forming or before security analysts have enough traditional event data or known patterns to detect a threat.
UEBA tools have an edge over traditional security analytics solutions as they don’t rely on predefined security rules or signatures. Instead, they employ machine learning algorithms to continuously learn and adapt to new patterns and behaviors. This adaptive learning makes them highly effective at detecting unknown threats, such as compromised credentials, zero-day exploits, and advanced persistent threats (APTs), which traditional security solutions are ineffective at detecting.
It’s important to note that UEBA tools can be highly effective as standalone solutions. This is especially true when looking at Insider Threat programs and the niche use cases associated with them. However, over the past few years we’ve seen the rise of UEBA solutions for augmenting traditional SIEM solutions in-order to fill gaps in their threat detection limitations. This has given way to a new pedigree of SIEM called Next-Gen SIEM, where UEBA tools are at the foundation of the modern architecture required for high-fidelity threat detections and unlocking AI within the SOC.
UEBA tools are designed with a multitude of capabilities that make them a valuable addition to any organization’s cybersecurity arsenal. Here’s an overview of the key features that UEBA tools possess:
UEBA tools provide early warnings by identifying potential risks and security threats as they are forming, enabling proactive threat mitigation before traditional event data or known patterns are available.
These tools employ machine learning algorithms to continuously adapt and learn new patterns and behaviors, making them highly effective at detecting unknown threats, such as compromised credentials, zero-day exploits, and advanced persistent threats.
UEBA tools can be highly effective as standalone solutions, especially in Insider Threat programs and niche use cases, offering robust security monitoring and anomaly detection capabilities.
UEBA solutions augment traditional Security Information and Event Management (SIEM) solutions, filling gaps in threat detection limitations and contributing to the emergence of Next-Gen SIEM, which is essential for high-fidelity threat detections.
UEBA tools form the foundation of modern architectures required for unlocking the potential of artificial intelligence within Security Operations Centers (SOC), leading to enhanced threat intelligence and response capabilities.
You can deploy a standalone UEBA tool for your insider threat program or augment the capabilities of your SIEM to further empower SOC analysts with higher-fidelity detections. Here are the top 5 use cases for UEBA tools:

By asking these 10 questions when evaluating UEBA vendors, you can make an informed decision and choose a solution that best aligns with your cybersecurity requirements and business objectives.
Gurucul’s UEBA tool is a standout product in the cybersecurity market, having pioneered the space over a decade ago prior to Gartner formalizing the term UEBA. Behavioral analytics is at the heart of Gurucul’s capabilities having dedicated extensive R&D toward providing enterprise customers with the clarity to predict, detect and respond to the most advanced unknown threats.
Gurucul’s User and Entity Behavior Analytics (UEBA) tool works by leveraging machine learning and advanced analytics to monitor and analyze the behavior of users and entities within an organization. Here’s how it functions:
The UEBA tool detects and analyzes abnormal behaviors establishing a baseline, assigns dynamic risk scores, and then, through integration with SOAR, triggers automated workflows to mitigate risks. This combination allows for faster and more efficient incident response, reducing the time and effort required for manual intervention. This approach helps in detecting insider threats, compromised accounts, and other security risks more effectively than traditional methods.
UEBA tools are increasingly essential for robust cybersecurity, with market growth reflecting their importance. UEBA tools utilize machine learning to monitor and analyze behavior, detecting anomalies and potential threats early on. They surpass traditional security solutions by continuously learning and adapting to new patterns, making them effective against advanced threats. Tools like Gurucul’s UEBA offer comprehensive features, including data aggregation, anomaly detection, and automated responses, integrating with SOAR for enhanced threat detection and incident response, ultimately strengthening an organization’s security posture.
User and Entity Behavior Analytics (UEBA) tools are advanced cybersecurity solutions that utilize machine learning and data science to monitor user and entity behaviors continuously. They identify deviations from established baselines to detect potential security threats, such as insider attacks and compromised accounts. It’s an ever-growing market. According to Grand View Research, the user and entity behavior analytics market has a “Revenue forecast in 2030 of USD 12.11 billion.” That’s compared to a market size value of “USD 1.61 billion in 2023.”
UEBA tools enhance cybersecurity by:
Detecting Anomalies: They analyze user behavior to identify unusual activity that may indicate a breach.
Early Warning Systems: UEBA tools provide early alerts about potential security risks before traditional methods can detect them.
Adaptive Learning: These tools continuously learn and adapt to new behaviors, improving their threat detection capabilities.
Predictive analytics in UEBA refers to using historical data and statistical algorithms to forecast potential future threats. By analyzing patterns in user behavior, UEBA tools can predict anomalies that may indicate malicious activities, allowing organizations to take proactive measures.
Dynamic risk assessment evaluates the risk associated with user and entity activities in real-time. UEBA tools assign risk scores based on behavioral anomalies, enabling organizations to respond quickly to emerging threats.
Data science is integral to UEBA as it involves:
Analyzing Large Data Sets: UEBA tools process vast amounts of data from various sources to establish behavioral baselines.
Applying Machine Learning: Algorithms learn from historical behavior to effectively identify patterns and detect deviations.
Improving Threat Detection: Data science techniques enhance the accuracy and efficiency of anomaly detection.
Real-time monitoring refers to continuously observing user and entity activities to detect suspicious behavior as it occurs. UEBA tools provide real-time insights, allowing organizations to respond instantly to potential security incidents.
Cross-vendor integration involves the ability of UEBA tools to work seamlessly with other security solutions, such as Security Information and Event Management (SIEM) systems. This integration enhances the overall security posture by providing a unified view of threats across different platforms.
User activity monitoring is a feature of UEBA tools that tracks and analyzes user interactions within an organization. By observing typical user behavior, these tools can identify anomalies that may signify security risks, such as unauthorized access or data exfiltration.
Forensic investigation capabilities refer to the features that allow UEBA tools to analyze and record user activities for security investigations. These capabilities include:
Detailed Activity Logs: Recording user actions for review during incidents.
