SentinelOne uses AI to detect and respond to active threats. WinSentinel eliminates attack surfaces before threats arrive by hardening Windows configuration. Together they form a complete defense-in-depth strategy.
| Capability | WinSentinel | SentinelOne |
|---|---|---|
| Primary Function | Proactive hardening & posture scoring | AI-powered EDR/XDR + autonomous response |
| Approach | Prevent — close attack surface before breach | Detect & respond — catch threats in progress |
| Security Posture Score | ✓ 0–100 across 33 audit modules | ✗ No configuration hardening score |
| Configuration Hardening | ✓ Auto-remediation with dry-run preview | ✗ Not a hardening tool |
| Threat Detection | Preventive (removes attack paths) | ✓ Real-time AI behavioral detection |
| Autonomous Response | Auto-fix misconfigurations | ✓ Kill/quarantine/rollback malicious processes |
| Rollback Capability | Dry-run preview before changes | ✓ Ransomware rollback via VSS |
| Open Source | ✓ MIT licensed, full source on GitHub | ✗ Proprietary, closed-source agent |
| Cloud Dependency | ✓ Fully local — no cloud required | Requires cloud console + connectivity |
| Setup Time | 30 seconds (dotnet tool install) | Agent deployment + cloud console setup |
| Windows-Specific Depth | ✓ 33 modules (registry, GPO, SMB, LLMNR, etc.) | Generic cross-platform agent |
| Compliance Mapping | ✓ CIS, SOC 2, HIPAA, Essential 8 | Limited (compliance dashboards are add-on) |
| CI/CD Integration | ✓ GitHub Action + SARIF output | ✗ Runtime-only, not CI/CD friendly |
| Agent Footprint | ~5 MB CLI, runs on demand | ~500+ MB always-on kernel agent |
| Privacy / Data Residency | ✓ All data stays local | Telemetry sent to SentinelOne cloud |
| MITRE ATT&CK Coverage | Maps findings to ATT&CK techniques | ✓ Full ATT&CK detection matrix |
$0/forever
All 33 audit modules, real-time monitor, scheduled scans, PDF reports — no limits on one machine.
Pro fleet: $29/25 nodes · $79/100 nodes
$6–12/endpoint/mo
Per-endpoint pricing. Annual commitment. Enterprise plans require sales call.
Control ~$6/ep · Complete ~$12/ep · Enterprise = custom
No configuration hardening. SentinelOne detects malware and suspicious behavior — it doesn't audit your Windows registry, GPO settings, firewall rules, or SMB configuration. If LLMNR is enabled or BitLocker is off, SentinelOne won't tell you.
No posture scoring. You can't get a single number representing your machine's security hygiene. No trend tracking, no "you improved from 67 to 84 this month."
No proactive prevention. It waits for something bad to happen, then responds. WinSentinel closes the doors and windows before the burglar arrives.
No local-only option. SentinelOne requires cloud connectivity and sends telemetry data off-machine. For air-gapped or privacy-sensitive environments, this is a dealbreaker.
No CI/CD pipeline fit. You can't run SentinelOne in a GitHub Action to verify your Windows image is hardened before deployment.
WinSentinel reduces your attack surface by 60–80% before SentinelOne even needs to fire. Fewer open ports, disabled legacy protocols, enforced policies — fewer alerts for your SOC team to triage.

No - they complement each other. SentinelOne uses AI to detect and respond to active threats. WinSentinel eliminates attack surfaces before threats arrive by hardening Windows configuration. Together they form a complete defense-in-depth strategy.
No. WinSentinel is a configuration-hardening and posture tool, not an endpoint detection and response product. It pairs with an EDR like SentinelOne rather than replacing it.
WinSentinel is free for unlimited use on a single machine. SentinelOne Singularity is per-endpoint EDR/XDR with annual contracts. 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.
