Trellix (formed from McAfee Enterprise and FireEye) is an enterprise XDR/EDR platform built to detect and respond to active attacks across endpoints, email and network. WinSentinel is purpose-built for Windows hardening with one-click auto-remediation — it closes the misconfigurations attackers exploit before detection ever matters.
| Capability | WinSentinel | Trellix |
|---|---|---|
| Primary Focus | Windows hardening & compliance | XDR / EDR / threat response |
| Security Model | Prevention by configuration hardening | Detection & response to active threats |
| Auto-Remediation | ✓ One-click fix for every finding | Guided response / remediation actions |
| Windows Hardening Depth | ✓ 33 specialized audit modules | ✗ Not a hardening/config-audit tool |
| Setup Complexity | 30 seconds (dotnet tool install) | ePO / Central console + agent rollout |
| Infrastructure Required | None (runs locally) | Managed platform (ePO / Trellix Central) |
| Real-Time Monitoring | ✓ Process, file, registry watch | ✓ Behavioral EDR telemetry |
| Security Score | ✓ 0–100 overall + per-module | ✗ No hardening posture score |
| Threat Intelligence | ✓ Threat Hunt engine + MITRE mapping | ✓ Insights threat intel + GTI |
| Compliance Mapping | ✓ CIS, SOC2, HIPAA, Essential 8 | Detection coverage, not config compliance |
| Managed Detection (MDR) | Not an MDR service | ✓ MDR / managed services available |
| Multi-Platform | Windows only (by design) | ✓ Windows, macOS, Linux |

Trellix watches for malicious behavior; it doesn't audit whether SMB signing, BitLocker, LSA protection, or WDigest are configured correctly. WinSentinel has 33 Windows-specific modules that query WMI, Registry, Group Policy, Defender, and Windows APIs directly.
XDR alerts you to an incident and helps you respond. WinSentinel generates FixEngine commands with one-click remediation for every misconfiguration it finds — you fix the weakness, not just chase the alert.
Trellix gives you detections and an investigation view, but no unified "how hardened is this machine?" score. WinSentinel gives you 0–100 overall and per-module scores with grade trends over time.
Trellix is a centrally managed platform requiring ePO / Central and an agent rollout. WinSentinel runs locally with zero infrastructure — install in 30 seconds, scan in 60, no account required.
Trellix is an operational security platform — it doesn't fit into GitHub Actions or build pipelines. WinSentinel ships as a GitHub Action with SARIF output for code scanning integration.
Trellix is quote-based enterprise software on annual contracts. WinSentinel is free and open source for unlimited single-machine use — the whole CLI and every audit module.
Trellix excels at detecting and responding to active threats across an operation. WinSentinel excels at hardening each Windows machine so there's less to detect in the first place. Run WinSentinel to close the misconfigurations attackers exploit, and let your XDR watch for what slips through. Prevention and detection, not either/or.
They solve different problems. Trellix (formed from McAfee Enterprise and FireEye) is an enterprise XDR/EDR platform that detects, investigates, and responds to active threats. WinSentinel is purpose-built for Windows hardening with one-click auto-remediation and installs in seconds. Prevention-by-hardening versus detection-and-response - they complement each other.
No. The free tier runs entirely on the local Windows machine - no ePO / Trellix Central console, no agent enrollment, no server to provision. That's the opposite of Trellix, which is a centrally managed platform with a per-endpoint enterprise sales motion.
WinSentinel is free for unlimited use on a single machine. Trellix is enterprise XDR/EDR sold per endpoint on annual contracts with quote-based pricing. 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 XDR platforms treat generically, which is why its hardening checks are deeper on Windows.
