Managed XDR vs. SIEM: Which one is right for your business?
Amid the twists and turns of today’s cyber security landscape, businesses face a critical decision: how to protect their systems, data, and reputation effectively. Two popular solutions—Managed Extended Detection and Response (Managed XDR) and Security Information and Event Management (SIEM)—offer distinct approaches to advanced threat detection and response.
But which one is right for your business? This guide will help you compare these solutions and make an informed choice.
Growing need for advanced threat detection
Cyber threats are increasing in frequency and sophistication. According to a report by IBM, the average cost of a data breach reached USD $4.88 million in 2024, a stark reminder of why robust threat detection is no longer optional. Businesses must proactively defend against these risks by implementing solutions that offer real-time insights, rapid responses, and comprehensive protection.
Managed XDR and SIEM represent two approaches to tackling these challenges.
Let’s explore what each offers.
What is SIEM? Core benefits
Security Information and Event Management (SIEM) is a solution designed to collect, aggregate, and analyse log data from across an organisation’s IT infrastructure.
Key Benefits of SIEM:
- Data Aggregation: SIEM collects logs from multiple sources, providing a centralised view of network activity.
- Compliance Support: It helps organisations meet regulatory requirements by generating detailed audit trails.
- Customisability: Advanced SIEM systems can be tailored to monitor specific threats or compliance needs.
- Threat Alerts: SIEM provides alerts for potential issues, although the response often relies on in-house expertise.
What is managed XDR? Core benefits
Managed Extended Detection and Response (Managed XDR) takes a broader, more integrated approach to cyber security. Unlike SIEM, Managed XDR not only collects and analyses data but also includes automated threat detection and response capabilities.
Key benefits of Managed XDR:
- All-in-One Solution: Combines threat detection, response, and remediation in a single service.
- Proactive Monitoring: Managed XDR includes 24/7 monitoring by security experts.
- Automated Responses: Reduces the need for manual intervention by automating threat containment and remediation.
- Outsourced Expertise: Ideal for businesses without extensive in-house cyber security teams.
Key differences between managed XDR and SIEM
When comparing Managed XDR and SIEM, several key differences stand out:
| Feature | SIEM | Managed XDR |
| Scope and Focus | Data aggregation and alerting | Active threat detection and response |
| Complexity and Cost | Requires in-house expertise; higher setup costs | Outsourced, cost-effective solution |
| Response Capability | Alert-focused, manual responses | Automated and integrated responses |
What is EDR vs. XDR vs. MDR vs. SIEM?
Understanding the terminology can clarify your options:
- EDR (Endpoint Detection and Response): Focuses on endpoint-level threats.
- XDR (Extended Detection and Response): Extends threat detection across endpoints, networks, and applications.
- MDR (Managed Detection and Response): A managed service for EDR or XDR capabilities.
- SIEM: Focuses on log aggregation and compliance support, requiring additional tools for active response.
| Solution | Coverage | Managed Service? | Automation Level |
| EDR | Endpoint-specific | No | Moderate |
| XDR | Multiple vectors | Yes | High |
| MDR | Endpoint or XDR (outsourced) | Yes | Moderate |
| SIEM | Logs and data aggregation | No | Low |
Which solution best fits my business?
Choosing between SIEM and Managed XDR depends on your business size, needs, and resources.
When SIEM is Ideal
- Larger organisations with dedicated in-house cyber security teams.
- Businesses requiring extensive customisation and regulatory compliance support.
- Those already invested in robust security infrastructure.
When managed XDR is Ideal
- Small to mid-sized businesses or organisations without large IT teams.
- Companies seeking a comprehensive, outsourced security solution with minimal complexity.
- Businesses prioritising proactive threat detection and rapid response.
