# xcitium knowledge base ## EDR - [What is EDR Security](https://www.xcitium.com/knowledge-base/edr-security/): EDR Security (Endpoint Detection and Response) is the cornerstone of modern cybersecurity, providing real-time threat detection, rapid response, and comprehensive protection for your organization's endpoints. ## XDR - [What is XDR] (https://www.xcitium.com/knowledge-base/xdr/): Extended Detection and Response (XDR) is an advanced cybersecurity solution that integrates multiple security components into a single platform to provide enhanced threat detection, investigation, and response capabilities. ## MDR -[What is MDR] (https://www.xcitium.com/knowledge-base/mdr/): Managed Detection and Response (MDR) is a cybersecurity service that combines advanced threat detection, continuous monitoring, and rapid incident response to protect organizations from cyber threats. ## Cloud Security - [What is Cloud Security] (https://www.xcitium.com/knowledge-base/cloud-security/): Cloud security is essential for safeguarding your data, applications, and workloads from evolving cyber threats. ## Zero-Day Exploits - [Zero-Day Exploits] (https://www.xcitium.com/knowledge-base/zero-day-exploit/): Zero-Day exploits are one of the most dangerous threats in cybersecurity, targeting unknown vulnerabilities before developers can patch them. ## Zero Trust Security - [Zero Trust Security] (https://www.xcitium.com/knowledge-base/zero-trust-security/): Zero Trust Security is a modern cybersecurity approach that eliminates implicit trust and continuously verifies every user, device, and application before granting access. ## Zero Trust Cybersecurity - [Zero Trust Cybersecurity] (https://www.xcitium.com/resources/knowledge-base/zero-trust-cybersecurity/): Zero Trust cybersecurity operates on the principle that no entity, whether inside or outside the network, should be inherently trusted. Instead, every access request must be verified continuously based on identity, device security posture, and context.
