Datadog Cloud SIEM (Security Information and Event Management) is a security data analysis and correlation system. It enables your entire security operations team to view, detect, investigate, and respond to security issues. Leveraging Datadog’s scalable platform, Cloud SIEM ingests telemetry from both cloud and on‑premises systems using the Datadog Agent and API-based integrations.
Effective security response requires speed, context, insight, and automation. Cloud SIEM continuously analyzes incoming data to detect threats, generate actionable security signals, and correlate them across multiple sources. This empowers your team to investigate incidents and respond quickly.
To keep your team on top of the latest attacks, Datadog also has a team of threat researchers who analyze petabytes of telemetry across cloud and on-premises systems to identify emerging threats and attacker behaviors. See Datadog Security Labs to read articles about their recent investigations.
Security and observability
Cloud SIEM embeds both cloud and on-premises telemetry directly into security workflows to accelerate investigation and response. And with a shared platform that brings DevOps and Security teams together, organizations can break down silos and respond to threats collaboratively and efficiently.
Flexible cost control for security data
As your organization scales, controlling the ingestion cost of security logs without compromising visibility is critical. Cloud SIEM is integrated with Datadog Log Management so you can choose the appropriate retention and querying capability for your security logs. This flexibility helps you balance cost efficiency with your threat detection needs.
Store logs using one of the available options:
Standard indexing for logs that need to be queried frequently with the most compute.
Flex Logs for logs that need to be retained long-term, but sometimes need to be queried urgently.
Log Archives for logs that are infrequently queried and need to be stored long-term.
Guided security data onboarding
Cloud SIEM Content Packs are a curated set of Datadog integrations designed for security teams. Each content pack has instructions on how to configure the integration and what is included, such as detection rules, out-of-the-box interactive dashboards, parsers, and SOAR workflows. Content Packs highlight actionable insights specific to each integration to help you investigate security issues.
Content pack health monitoring
After a content pack is activated, it gives you the integration’s health status and provides troubleshooting steps if something goes wrong so you can get back up and operational as fast as possible.
Log search and analysis
Build searches in the Log Explorer using facets or by clicking fields directly in the logs. Or use Bits AI and natural language search to find important security events. With built-in group-by and table lookup functions as well as pattern analysis and visualizations, security teams can get security insights from their data. See Log Explorer and Log Search Syntax for more information.

A high-level overview of all signals.
Signal Distribution
On the left side of the section, see signals grouped by severity and trend over the selected time window.
On the right side, see a break down of signal activity by severity, source, and resolution. Click on a node in the sankey diagram to see signals in the Signal Explorer filtered to the specifics of that node.
Mean Time to Respond to Signals
See KPIs of how quickly your team responds. Click a severity tile to view signals set to under review or archive and filtered to the selected severity.
MITRE ATT&CK coverage
Detection rule coverage and signal activity by MITRE ATT&CK tactics and techniques.
Techniques with at least 1 rule
See how many techniques are covered by the detection rules enabled in your environment.
Rule density KPIs
See how many techniques have high, medium, or low density or no rules at all. Click on a tile to view a filtered MITRE map.
Signals per tactic view
See which MITRE ATT&CK tactics are generating signals. Click a pie chart wedge to view the Signal Explorer filtered by that tactic. Click the dropdown and select Rules count to see which tactics have the most rules mapped to it.
