Why Every Windows Dev Should Run a Security Audit

If you write code on Windows, your machine likely has: SSH keys, cloud credentials, access tokens, API keys, database connection strings, and maybe even production secrets cached in environment variables or config files. A compromised dev machine is a shortcut past every perimeter defense your company has.

Yet most developers never audit their own workstation. Why?

• "IT handles security" — IT manages group policy but can't see your personal browser extensions, sideloaded tools, or disabled Defender.
• "I'd know if something was wrong" — Most misconfigurations are silent. Disabled firewall on Public profile? No popup. Stale Windows updates? No notification after you clicked "remind me later" six months ago.
• "Security tools are enterprise-only" — True for Nessus, Qualys, CrowdStrike. Not true for WinSentinel.

The 60-second audit

dotnet tool install --global WinSentinel.Cli
winsentinel --score

You'll get a score out of 100 with a letter grade. Most developer machines land between 65–80 on first run. The findings that drop your score are usually:

• Windows Firewall disabled on one profile (usually Public)
• Outdated Windows patches (30+ days behind)
• Guest account enabled
• RDP enabled without NLA
• AutoRun still on for USB drives
• PowerShell execution policy set to Unrestricted

Each finding is fixable in one command or one registry edit. WinSentinel shows you exactly what and where.

But I'm on a personal machine…

Doesn't matter. If you git push to work repos, SSH into production, or access cloud consoles from this machine, it's a work machine. Treat it like one.

The machine that has your SSH keys is the machine that matters.

Run an audit. Fix the critical findings. Set up a weekly schedule with winsentinel schedule create --cadence weekly so drift doesn't sneak back in. Your future self — and your security team — will thank you.
