Frequently asked questions
Is MDR better than XDR?
MDR (Managed Detection and Response) and XDR (Extended Detection and Response) serve different roles. MDR is a fully managed security service that includes human-led threat detection, investigation, and response. XDR is a technology-driven platform that integrates multiple security tools to improve visibility and automate threat detection. If your organization lacks an in-house SOC team, MDR is a better choice for 24/7 expert protection.
What does MDR stand for?
MDR stands for Managed Detection and Response, a cybersecurity service that combines AI-driven detection with human security analysts to provide continuous monitoring, rapid incident response, and proactive threat hunting.
How big is the MDR market?
The MDR market is rapidly expanding due to the rising number of cyberattacks and the need for businesses to outsource security operations. Industry reports estimate the global MDR market will exceed $5 billion by 2027, growing at a CAGR of over 20%.
What is MDR for small businesses?
MDR for small businesses provides enterprise-level security without the need for a full in-house security team. It offers affordable, scalable protection, 24/7 monitoring, rapid response, and compliance support, making it a cost-effective solution for SMBs that need to safeguard against cyber threats.
What is included in MDR services?
MDR services typically include:
- 24/7 threat monitoring & response
- Proactive threat hunting
- Incident investigation & forensics
- Security log management & SIEM integration
- Compliance support (SOC 2, ISO 27001, HIPAA, PCI DSS).
How does MDR compare to MSSP?
An MSSP (Managed Security Service Provider) mainly focuses on log monitoring and alerting, whereas MDR actively investigates, responds to, and contains threats. MDR provides hands-on security expertise and incident response, while MSSPs typically stop at alerting.
How much does MDR cost?
MDR pricing varies depending on the service level, organization size, and provider. Most MDR services use a per-endpoint, per-user, or tiered pricing model. Costs typically start at $30-$100 per endpoint per month but can scale based on custom integrations and response capabilities.
Does MDR help with compliance?
Yes, MDR helps businesses meet SOC 2, ISO 27001, HIPAA, PCI DSS, and other security regulations by providing continuous monitoring, log management, threat detection, and audit-ready reports.
Can MDR replace SIEM?
MDR and SIEM (Security Information and Event Management) serve different functions. MDR provides active threat response and investigation, while SIEM collects and analyzes security logs. Many businesses use both MDR and SIEM for a stronger security posture.
How do I choose the best MDR provider?
When selecting an MDR provider, consider:
- Threat detection & investigation capabilities
- Response time & 24/7 SOC availability
- Technology integrations (SIEM, XDR, cloud security, endpoint protection)
- Compliance support (SOC 2, HIPAA, PCI DSS, ISO 27001)
- Pricing transparency & service scalability.
