## Overview
58

-
Datadog Cloud SIEM (Security Information and Event Management) unifies developer, operation, and security teams on one platform. Use a single dashboard to display DevOps content, business metrics, and security insights. Cloud SIEM detects threats to your applications and infrastructure, such as targeted attacks, communications from threat intel-listed IP addresses, and insecure configurations, in real time. Notify your team of these security issues by email, Slack, Jira, PagerDuty, or webhooks.
59
+
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.

61
+
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.
62
62
63
-
Threats are surfaced in Datadog as Security Signals and can be correlated and triaged in the [Security Signals Explorer][1]. Security Signals are generated by Datadog Cloud SIEM with [Detection Rules][2]. Detection Rules detect threats across different sources and are available out of the box for immediate use. You can clone any of the provided detection rules to change the configuration. You can also add a [new rule][3] from scratch to fit your specific use case.
63
+
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][1] to read articles about their recent investigations.
64
+
65
+
### Security and observability
66
+
67
+
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.
68
+
69
+
### Flexible cost control for security data
70
+
71
+
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.
72
+
73
+
Store logs using one of the available options:
74
+
-[Standard indexing][6] for logs that need to be queried frequently with the most compute.
75
+
-[Flex Logs][7] for logs that need to be retained long-term, but sometimes need to be queried urgently.
76
+
-[Log Archives][8] for logs that are infrequently queried and need to be stored long-term.
77
+
78
+
### Guided security data onboarding
79
+
80
+
Cloud SIEM [Content Packs][9] 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.
81
+
82
+
### Content pack health monitoring
83
+
84
+
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.
85
+
86
+
### Log search and analysis
87
+
88
+
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][11] and [Log Search Syntax][10] for more information.
