CyberArk Privileged Threat Analytics

SIEM solutions have long faced practical limits in defensive effectiveness despite high expectations. Real-world experience shows that the volume of logs and events is difficult to calibrate well enough to reliably distinguish benign anomalies from serious incidents requiring rapid response, making SIEM more effective for auditing and compliance than real-time attack response. In response, Real-Time Security Intelligence (RTSI) emerged as an evolution: it still aggregates and correlates activity data, but applies advanced analytics from big data and business intelligence to enable continuous self-calibration and, in modern solutions, automated mitigation.

Because compromised privileged access can cause outsized damage, risk mitigation should start with the highest-impact accounts and entitlements—typically administrator/root credentials—rather than attempting to monitor everything equally. Privilege Management is therefore increasingly a mandatory element of enterprise security, with vendors offering discovery, vaulting, monitoring, and in some cases real-time analytics.

CyberArk Privileged Threat Analytics (PTA) exemplifies an RTSI-style approach targeted at privileged misuse. Version 3.0 adds automated response to contain attacks by invalidating suspected compromised privileged credentials, plus the ability to gather and analyze network traffic using existing tap/mirroring infrastructure. This enables deterministic detection of in-progress Kerberos attacks, including Golden Ticket attacks that are otherwise difficult to detect without correlating authentication events and network data. PTA combines deterministic attack-pattern algorithms (continuously updated) with statistical, deployment-specific baselining that improves over time, while keeping configuration minimal.

PTA integrates bidirectionally with SIEM: it can ingest SIEM events about privileged systems and feed SIEM alerts, evidence, and response actions, allowing SIEM to remain an enterprise-wide monitoring/compliance layer while PTA specializes in privileged threat detection and response. Remaining challenges include limited managed services options and difficulty handling planned maintenance windows that deviate from baseline behavior without generating alerts or risking miscalibration.

• SIEM implementations commonly struggle to separate innocuous events from serious incidents due to the overwhelming quantity of collected logs and events.
• SIEM tools have often proven more useful for auditing and compliance than for reliable real-time response to serious attacks.
• Real-Time Security Intelligence relies on analytics to perform continuous self-calibration rather than manual calibration of anomalous activity.
• Privilege Management has become a mandatory component of many enterprise security infrastructures.
• CyberArk was founded in 1999 and has focused on monitoring and control of privileged access.
• CyberArk Privileged Threat Analytics 3.0 can automatically invalidate privileged credentials deemed to be compromised.
• Privileged Threat Analytics 3.0 can gather and analyze network traffic using existing network tap aggregators or switch port mirroring.
• The product can detect in-progress Kerberos attacks by deterministically identifying anomalous Kerberos authentication traffic.
• The solution includes detection algorithms for a Kerberos “Golden Ticket” attack exploiting a known Active Directory vulnerability.
• SIEM integration with Privileged Threat Analytics is bidirectional, supporting both ingest of privileged-system events and export of anomaly alerts.

• “This difficulty has made SIEM tools more useful for auditing and compliance requirements than as a reliable tool for responding in real time to serious attacks.”
• “Instead of taking an all-or-nothing approach, risk mitigation should start with those accounts, systems or entitlements that have the potential to cause the greatest detrimental impact to an organisation should they be compromised.”
• “It is here that risk mitigation should begin.”
• “Modern RTSI solutions should not only be able to now detect serious threats, but should also be capable of automatic mitigation responses to perceived threats.”
• “A key improvement of Privileged Threat Analytics 3.0 is its new automated response capability.”
• “This additional source of data allows Privileged Threat Analytics 3.0 to detect in-progress Kerberos attacks by deterministically identifying anomalous Kerberos authentication traffic.”
• “There is little to configure when it comes to the analytical algorithms, which is both a product strength and a challenge.”
• “Privileged Threat Analytics builds a behavioural profile of all privileged users, accounts and systems, which is how it is able to distinguish between regular and anomalous usage patterns.”
• “The focus with high-risk, privileged access must be on detection and response, in contrast to purely forensic analysis given the potentially severe impact the abuse of privileged access can cause to an organisation.”
• “Overall, we strongly recommend evaluating CyberArk Privileged Threat Analytics both in the context of existing CyberArk deployments and in the context of SOC infrastructures.”
