Build Smarter Threat Detection with Next-Gen SIEM

SOC teams across businesses, industries, and geographies share the same goal: Stop cyberattacks before damage is done. But for those with legacy SIEMs, this is nearly impossible to achieve. Legacy SIEMs demand an overwhelming investment of time, resources, and expertise to set up and maintain.

Legacy SIEMs force SOC teams to manually define every possible attack scenario and ingest massive amounts of data to detect threats, creating complexity and driving up costs. Next, they must build thousands of rules to cover every attack scenario, from malware to insider threats, across every stage of the kill chain. Although most SIEMs provide default correlation rules, detection engineers must customize these rules for their unique environments and update them to keep pace with evolving threats and changing log formats.

Despite the massive effort poured into building correlation rules, SIEMs still flood analysts with low-fidelity alerts. Analysts spend up to two hours every day investigating false positives, increasing burnout and delaying response. The traditional SIEM model isn't just inefficient — it's broken. Teams need a new approach. 

Mehmet Halit Sumen, Head of IT for Domino’s Pizza Eurasia, faced this precise challenge: “Our biggest challenge was false positives,” he said. “Any policy we enforce within our network might cause an outage. And since we operate 24/7, any outage can result in revenue loss … so it’s important our SOC operates efficiently and effectively.” 

Detection Powered by Data, AI, and Deep Adversary Insights

CrowdStrike redefines SIEM by combining the right data, AI, and expert-driven analytics for superior threat detection. The goal is simple: to deliver accurate, up-to-date detections that work from the start and offer maximum coverage with minimal tuning. This empowers teams to adapt at the pace of the adversary, an evolution that sets CrowdStrike Falcon® Next-Gen SIEM apart from its predecessors.

Falcon Next-Gen SIEM is built for faster threat detection. It collects and processes data quickly, avoiding the ingestion bottlenecks of legacy tools. Because it tightly integrates with CrowdStrike’s endpoint security, threat intelligence, and SOAR capabilities, it can detect attacks immediately, without waiting for data handoffs or separate tools to trigger alerts and start triage workflows. This eliminates delays and ensures teams are always a step ahead of threats. 

While organizations need visibility across dozens or even hundreds of data sources to detect threats, most detections come from just a few key data sources. Falcon Next-Gen SIEM simplifies detection engineering by focusing on these critical sources and delivering thousands of prebuilt, high-fidelity detections — ready to go on Day One, no rule-building required. 

CrowdStrike accomplishes this by integrating industry-leading endpoint detection and response, identity protection, cloud security, and next-gen SIEM into a single platform. With over 10,000 indicators of attack (IOAs), customers see immediate value and streamlined rule management. A U.S. pharmaceutical company, for example, deprecated 60-70% of its correlation rules by switching from a legacy SIEM to Falcon Next-Gen SIEM and leveraging the endpoint detections already in the CrowdStrike Falcon® platform.

By unifying security operations, Falcon Next-Gen SIEM reduces complexity and costs. Teams save on detection engineering while avoiding redundant ingestion and storage of key data sources, boosting efficiency and improving return on investment.

Detecting Advanced Attacks with AI and the Power of the Crowd

Falcon Next-Gen SIEM unlocks the full potential of AI by combining cloud-scale processing with a deep understanding of key data sources such as endpoint, cloud, and identity data. It applies machine learning to massive volumes of events to power AI-driven detections that identify attacks with laser precision. It can also interpret scripting languages and commands to expose malicious behaviors that legacy SIEMs miss.

CrowdStrike automatically updates detections to identify new attack techniques and behaviors. Unlike legacy SIEMs’ static, noisy correlation rules, the AI-powered detections in the Falcon platform evolve to counter changing threats, eliminating the inefficiencies of manual rule maintenance. This is more than an improvement — it’s a fundamental shift in how security operates at scale.

Extending Industry-Leading Detection to All Data Sources

Attacks can come from anywhere — network devices, email gateways, user credentials, IoT, and more — and target anything. To deliver complete visibility and protection, Falcon Next-Gen SIEM connects the dots to correlate data and uncover the stealthiest attacks.

It detects techniques across the entire cyber kill chain with out-of-the-box correlation rules mapped to both specific adversaries and the MITRE ATT&CK® framework. Hundreds of precision-engineered correlation rules, combined with thousands of AI-powered IOAs for key data sources, empower teams to detect nearly any type of attack.

Falcon Next-Gen SIEM lets teams build custom correlation rules with a single, intuitive query language — the same one used for search and dashboards. Teams can streamline operations by adding custom attributes, or tags, to detection rules, simplifying rule management and organization. They can choose whether correlation rules will generate detections or incidents for added flexibility, and can stay connected with instant alert notifications via email, Slack, and more. 

A Crystal-Clear View of Detection Coverage

Legacy SIEMs depend on massive rule sets, but without the right data, detections can fail or never trigger at all, making coverage maps unreliable. Falcon Next-Gen SIEM changes that by streamlining collection of key data, providing a real-time view of defenses, and showing how detection posture evolves as new rules are added.

Detection engineers can easily see which ATT&CK techniques Falcon Next-Gen SIEM can detect, identify gaps in coverage, and determine the data sources needed to close them. They can also map data rules to specific adversaries and see which rules trigger the most alerts to fine-tune them and reduce false positives. Detection Coverage helps teams discover blind spots and strengthen their security posture to stay ahead of evolving threats.

Maximizing Next-Gen SIEM with Next-Generation MDR

Just like legacy tools, outdated approaches to managed security fall short. Organizations need professionals who deeply understand their technology and can deliver around-the-clock monitoring, lightning-fast threat detection, expert analysis, and comprehensive remediation. Next-gen managed detection and response (MDR) isn’t just about detection — it’s about decisive action. That’s exactly what CrowdStrike Falcon® Complete Next-Gen MDR delivers.

Falcon Complete Next-Gen MDR combines world-class security experts with cutting-edge technology to stop breaches. At its core are advanced, high-fidelity detections, built by a dedicated team of detection engineers who leverage elite threat intelligence and real-world attack patterns. This continuous feedback loop sharpens detection accuracy, helps analysts stop threats earlier in the kill chain, and fuels new detections in Falcon Next-Gen SIEM.

 DJ Goldsworthy, VP of Security Operations at Aflac, shares his company’s experience: “When we started, we had a large SOC and built most of our detections ourselves. Since shifting to Falcon Complete Next-Gen MDR, alerts have dropped 20x. It's head-over-heels more mature and effective than what we had in the past.”

Take Detection Capabilities to the Next Level

Legacy SIEMs, burdened by massive sets of manually defined rules, often fail to catch modern attacks. Next-generation approaches, like Falcon Next-Gen SIEM, deliver up-to-date, cloud-native detection capabilities, including expertly crafted correlation rules that enhance protection across the environment. AI-powered IOAs for critical data sources identify stealthy threats without time-consuming rule building and tuning. For teams that need extra support, Falcon Complete Next-Gen MDR acts as a force multiplier, delivering continuous threat detection, investigation, and response to enhance SOC operations.

This is what next-gen SIEM is all about: uncovering advanced threats and stripping away the noise so you can focus on stopping breaches.
