Wazuh is a powerful open-source SIEM/XDR — built for Linux first. WinSentinel is purpose-built for Windows hardening with auto-remediation. Different tools, different missions.
| Capability | WinSentinel | Wazuh |
|---|---|---|
| Primary Focus | Windows hardening & compliance | SIEM / XDR / Log analysis |
| Platform DNA | Windows-native (.NET) | Linux-first (C, Python) |
| Auto-Remediation | ✓ One-click fix for every finding | ✗ Active response (scripts) — manual setup |
| Windows Hardening Depth | ✓ 33 specialized audit modules | SCA policy checks (generic CIS) |
| Setup Complexity | 30 seconds (dotnet tool install) | Manager + Agent + Indexer stack |
| Infrastructure Required | None (runs locally) | Linux server (4+ cores, 8GB+ RAM) |
| Real-Time Monitoring | ✓ Process, file, registry watch | ✓ File integrity + log collection |
| Security Score | ✓ 0–100 overall + per-module | ✗ No unified score |
| Threat Intelligence | ✓ Threat Hunt engine + MITRE mapping | ✓ MITRE + VirusTotal + YARA |
| Compliance Mapping | ✓ CIS, SOC2, HIPAA, Essential 8 | ✓ PCI-DSS, HIPAA, GDPR, CIS |
| Log Analysis / SIEM | Event log audit (Windows focus) | ✓ Full SIEM with indexing |
| Vulnerability Detection | ✓ Outdated software + weak configs | ✓ CVE database scanning |
| Multi-Platform | Windows only (by design) | ✓ Linux, Windows, macOS |
| Open Source | ✓ MIT license | ✓ GPL v2 |

Wazuh's "active response" requires you to write and maintain custom scripts. WinSentinel generates FixEngine commands with one-click remediation for every finding.
Wazuh's SCA checks are cross-platform YAML policies. WinSentinel has 33 Windows-specific modules that query WMI, Registry, Group Policy, Defender, BitLocker, and Windows APIs directly.
Wazuh gives you alerts and compliance check results, but no unified "how secure is this machine?" score. WinSentinel gives you 0–100 overall and per-module scores with grade trends over time.
Wazuh needs a dedicated Linux manager server plus Elasticsearch/OpenSearch indexer. WinSentinel runs locally with zero infrastructure — install in 30 seconds, scan in 60.
Wazuh is an operational security tool — it doesn't fit into GitHub Actions or build pipelines. WinSentinel ships as a GitHub Action with SARIF output for code scanning integration.
Wazuh excels at cross-platform SIEM and log analysis. WinSentinel excels at deep Windows hardening and auto-fix. Run WinSentinel on your Windows endpoints for hardening + auto-remediation. Run Wazuh for centralized log analysis and alerting. They're complementary, not competing.
They overlap but differ in focus and effort. Wazuh is a self-hosted SIEM/XDR built Linux-first that you must deploy and maintain. WinSentinel is purpose-built for Windows hardening with auto-remediation and installs in seconds. Different missions - log/event analytics versus configuration hardening.
No. The free tier runs entirely on the local Windows machine. There's no manager, indexer, or dashboard server to stand up - that complexity is exactly what WinSentinel avoids for single-machine hardening.
WinSentinel is free for unlimited use on a single machine. Wazuh is free and open source, but it's a self-hosted SIEM/XDR you operate yourself. WinSentinel Pro - which adds fleet management across many machines - is $29/mo for up to 25 nodes or $79/mo for up to 100 nodes, with annual billing saving 17%.
Yes. The CLI and every audit module are free and open source under the MIT license, installed with dotnet tool install --global WinSentinel.Cli. A single machine gets the full power - all audit modules, the real-time monitor, scheduled scans, and PDF reports - with no limits and no account required. Pro is only for organizations that want to manage many machines from one control plane.
Yes. WinSentinel is built specifically for Windows 10 and Windows 11 (and Windows Server). It uses native Windows APIs to audit configuration that cross-platform tools treat generically, which is why its hardening checks are deeper on Windows.
