Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

If you have ever built a LEGO set, then you have a general idea of how telemetry works. Telemetry starts with individual data points, just like your LEGO build starts with a box of bricks. In complex IT environments, your security telemetry is spread across different technologies and monitoring tools, just like in a large build your LEGO bricks come separated into smaller, individually numbered bags. In both cases, the individual bricks or data points aren’t special.

Security teams often struggle to keep up with rapidly evolving threats, especially when they have to manually manage detection rules. Without automation or version control, it's difficult to maintain consistency across environments, track changes, or deploy updates quickly. Datadog Cloud SIEM supports detection as code, a structured approach to authoring, testing, deploying, and managing detection rules using code and infrastructure-as-code tools like Terraform.

Security analysts face unprecedented challenges in today's cloud landscape. Security operations center (SOC) teams are chronically understaffed, and cybersecurity threats are skyrocketing—further intensified by GenAI-driven attacks. High false positive rates add to this strain, fueling alert fatigue and delaying the detection of real threats. These hurdles make it harder for analysts to keep pace, which ultimately drives up mean time to resolution (MTTR).

The traditional approach to managing security operations centers (SOCs) is straining the mental and physical reserves of even the most skilled security analysts—while also failing to provide the protection organizations need against today’s threats. Analysts are left to respond to a never-ending stream of alerts, resulting in an overwhelming, reactive cycle that stifles proactive investigation and threat hunting.

The decision to buy a Security Information and Event Management (SIEM) product or outsource to a Managed Detection and Response (MDR) depends on a number of factors, including the size of your organization, the complexity of your IT infrastructure, and your overall security needs. Before we get into the main discussion, let’s step back and define what we are talking about so everyone is on the same page.
