Wazuh replaces Microsoft Defender, Sentinel, and Defender for Cloud with open-source unified security: file integrity monitoring, threat detection, vulnerability scanning, and compliance dashboards.
Wazuh is an open-source security platform that unifies SIEM, XDR, and compliance monitoring in a single solution. Used by thousands of organizations worldwide, it provides the capabilities of Microsoft Defender, Sentinel, and Defender for Cloud without per-agent or per-GB licensing.
Wazuh deploys lightweight agents on every endpoint -- Windows, macOS, Linux, Solaris, and more. These agents collect log data, monitor file integrity, detect vulnerabilities, assess security configuration, and respond to threats in real time. All data flows to the Wazuh manager for correlation, alerting, and dashboarding.
The Wazuh dashboard (built on OpenSearch Dashboards) provides full visibility: security events, alerts by severity, MITRE ATT&CK mapping, compliance status, and vulnerability inventory. Custom rules and decoders let you tailor detection to your specific environment. Active response modules can automatically block IPs, kill processes, or quarantine files.
Last updated:
Real-time detection of file changes on critical system files, configuration files, and sensitive directories. Know instantly when files are created, modified, or deleted with full audit trails.
Over 4,000 built-in detection rules mapped to MITRE ATT&CK. Anomaly detection, rootkit scanning, and active response. Automatically block malicious IPs, kill suspicious processes, or quarantine files.
Continuous scanning of installed software against CVE databases (NVD, Red Hat, Canonical). Prioritize patching by CVSS score and exploitability. Track remediation progress per endpoint.
Centralized log collection from endpoints, network devices, firewalls, and applications. Real-time correlation, alerting, and forensic search. Replaces Microsoft Sentinel at zero ingestion cost.
Pre-built dashboards for HIPAA, PCI-DSS, GDPR, NIST 800-53, and CIS benchmarks. Security Configuration Assessment (SCA) checks endpoints against hardening standards.
Monitor AWS, Azure, GCP, and Docker/Kubernetes environments. Detect misconfigurations, unauthorized access, and policy violations across cloud infrastructure.
Wazuh is an open-source unified SIEM and XDR platform. It provides file integrity monitoring, log analysis, intrusion detection, vulnerability scanning, security configuration assessment, incident response, and compliance dashboards. It replaces Microsoft Defender for Endpoint, Defender for Cloud, and Microsoft Sentinel with a single, self-hosted platform at zero per-agent licensing cost.
Yes. Wazuh includes pre-built compliance dashboards and rule sets for HIPAA, PCI-DSS, GDPR, NIST 800-53, and CIS benchmarks. It provides the audit logging, file integrity monitoring, access control verification, and continuous monitoring required by these frameworks. Because data is self-hosted, data residency requirements are easier to meet than with cloud-based alternatives.
Wazuh uses a combination of signature-based detection (over 4,000 built-in rules), anomaly detection, and integration with threat intelligence feeds (MITRE ATT&CK, VirusTotal, AbuseIPDB). It correlates events across endpoints, network devices, and applications in real time. While Defender relies on Microsoft's cloud-based intelligence, Wazuh gives you full control over detection rules and can be customized for your specific environment.
Yes. Wazuh agents run on Windows, macOS, Linux, Solaris, AIX, and HP-UX. The agent is lightweight (under 50MB RAM), runs as a service, and communicates with the Wazuh manager over encrypted channels. All platforms get the same capabilities: FIM, vulnerability scanning, log analysis, and active response.
Wazuh scales horizontally. A single Wazuh manager can handle up to 10,000 agents. For larger deployments, multi-node clusters with load balancing are supported. Infrastructure requirements are modest: a 4-core, 8GB RAM server handles 100-500 agents comfortably. Data is stored in the Wazuh Indexer (based on OpenSearch), which can be clustered for high availability and retention.
