Arctic Wolf is a cloud-delivered managed security operations platform — a 24/7 SOC, Managed Detection and Response, Managed Risk, and a named Concierge Security Team that watches your telemetry and walks you through incidents, sold per-seat on annual contracts. WinSentinel eliminates the misconfigurations attackers exploit before any alert fires — auditing and hardening Windows, then scoring it — for free and fully local. Harden first, then let the SOC monitor what's left.

MDR · Managed Risk · Security Awareness · 24/7 SOC
No configuration hardening. Arctic Wolf monitors telemetry and advises on risk — it doesn't audit your Windows registry, GPO settings, firewall rules, or SMB configuration and then fix them. If LLMNR is enabled, SMBv1 is on, or BitLocker is off, the SOC may eventually flag the resulting incident, but it won't remediate your config for you.
No posture scoring. You can't get a single number representing your machine's configuration hygiene, or track "you improved from 67 to 84 this month." Arctic Wolf reports detections, risks and incidents through its portal, not a Windows configuration benchmark score.
No proactive prevention of misconfiguration. Its model is monitor-detect-respond, with a human team in the loop after telemetry arrives. WinSentinel closes the doors and windows — disabled legacy protocols, enforced policies, locked-down accounts — before any payload ever lands or any alert is raised.
No local-only / self-service config audit. Arctic Wolf is delivered as a cloud platform that requires onboarding, sensor deployment, and log shipping to its SOC; you can't run a one-shot, air-gapped configuration audit with no account or telemetry egress. WinSentinel runs entirely on the machine, free, with no account.
No CI/CD pipeline fit. You can't drop Arctic Wolf's managed SOC into a GitHub Action to verify your Windows image is hardened before it ships. WinSentinel gates your build with --audit --sarif and uploads to GitHub code scanning.
WinSentinel reduces your attack surface by 60–80% before Arctic Wolf's SOC ever raises an alert. Fewer open ports, disabled legacy protocols, enforced policies, encrypted volumes — fewer footholds for attackers to gain, fewer incidents for the Concierge Security Team to triage, and a cleaner Windows baseline for Managed Risk to measure.
dotnet tool install --global WinSentinel.Cli winsentinel --audit --score
No - they solve different problems and work well together. Arctic Wolf is a managed security operations platform: its Concierge Security Team and 24/7 SOC monitor your telemetry, hunt threats, triage alerts, and walk you through incident response across your whole environment. WinSentinel eliminates the misconfigurations attackers exploit before any alert fires - it audits and hardens Windows configuration (registry, GPO, firewall, SMB, BitLocker, accounts) and scores your posture. Harden with WinSentinel, get monitored and managed by Arctic Wolf.
No. WinSentinel is a configuration-hardening and posture tool, not a managed service. There are no analysts, no 24/7 monitoring, and no incident-response team - it is a CLI you run yourself. It audits how Windows is configured and fixes the misconfigurations a SOC would otherwise have to notice after the fact, like SMBv1 being on, LLMNR enabled, BitLocker off, or local admin sprawl.
WinSentinel is free for unlimited use on a single machine. Arctic Wolf does not publish list pricing; it is sold through annual contracts scoped to your environment (users, endpoints, and the modules you buy - Managed Detection and Response, Managed Risk, Managed Security Awareness), typically a five- to six-figure annual commitment with a multi-year term. 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%.
No - and that is the point. Arctic Wolf's strength is continuous human-led monitoring: its SOC ingests logs from your endpoints, network, cloud and identity providers and a named security team watches them around the clock. WinSentinel does not duplicate that; it removes the attack surface those threats need - disabled legacy protocols, enforced policies, locked-down accounts, encrypted volumes - so there is less for the SOC to catch in the first place. They are complementary layers, not substitutes.
No. WinSentinel runs fully local - the CLI audits the machine it runs on and keeps all data on that machine, with no account, no sensor deployment, no log shipping, and no cloud connectivity required. Arctic Wolf requires onboarding with your Concierge Security Team, deploying sensors and log collectors, and streaming telemetry to the Arctic Wolf cloud. WinSentinel's optional Pro control plane is opt-in and only for organizations that want fleet management.
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. Arctic Wolf monitors across Windows, macOS, Linux, cloud and SaaS from its platform, but it does not provide a Windows configuration posture score or one-click config remediation.
Yes. WinSentinel is a lightweight CLI that reads Windows configuration and applies opt-in fixes on demand - it is not an always-on agent, does not install a real-time scanning driver, and does not hook process execution, so it runs cleanly next to Arctic Wolf sensors or any other agent. Hardening with WinSentinel reduces the number of incidents Arctic Wolf's SOC has to triage, and its Managed Risk module will see a cleaner Windows baseline.
