Unified security information and event management platform

One platform,
total control.

Centralize your security operations

Bring log data, security alerts, and threat intelligence into one platform. Sekoia Defend connects your existing security stack, including cloud services, so teams gain centralized visibility across multiple systems. The platform supports data collection, normalization, and log management without forcing teams to work across disconnected tools.

Make security data easier to analyze

Use dashboards, reporting, and unified search to analyze data across your environment. Advanced analytics help teams investigate activity, identify patterns, and improve their organization’s security posture.

Focus analysts on real threats

Native threat intelligence, entity behavior analytics, and contextualized security alerts help teams reduce false positives. Security analysts can then spend more time investigating suspicious activity and potential security breaches.

Respond faster and with more confidence

Continuous detection, case management, and security orchestration help teams accelerate incident response. Playbooks support automated responses while keeping actions consistent and auditable.

Do you have any questions about SIEM?

What is a SIEM?

SIEM stands for Security Information and Event Management. A SIEM combines security information management with security event management, collecting and analyzing activity from across an organization’s IT environment.

A SIEM solution gives security teams centralized visibility into security events, log data, and security alerts. It helps security analysts identify suspicious activity, investigate incidents, and coordinate incident response from one platform.

Sekoia Defend is an agentic security information & event management tool for modern security operations.

How does a SIEM work?

A SIEM (security information & event management platform) collects data from network devices, servers, endpoints, and other security systems. It normalizes the log and event data so teams can analyze activity consistently.

The platform can analyze log data, correlate related events, and identify suspicious behavior through detection rules, threat intelligence, and machine learning.

When the SIEM identifies a potential threat, it creates a security alert for the team to review. Analysts can then investigate the activity and coordinate incident response from the same event management system.

Why is a SIEM important?

Cyber threats often affect more than one system. A SIEM connects related security events across your environment so teams can identify patterns that may be difficult to see in separate tools.

SIEM platforms support comprehensive security monitoring and help teams investigate external threats, insider threats, security breaches, and other security issues.

A SIEM also stores historical security events that can support compliance reporting and compliance management.

How do you effectively deploy a SIEM solution?

Start by connecting the most important data sources in your environment. Focus on the systems that hold the information your security team needs to monitor first.

Then, define the detection use cases that matter most to your organization. Tune the rules to match normal activity so analysts can focus on credible threats and reduce false positives.

Finally, connect your SIEM software to security orchestration and response tools. This gives teams a practical way to investigate alerts, manage security incidents, and trigger automated actions when appropriate.
