CastelGuard Tools

Built in-house, tested on my own business first, and available to you.

Most consultants sell you a checklist. I build the tools myself, run them against my own company before I ever bring them to a client, and I'm happy to show you exactly how they work. If you'd rather see the code than take my word for it, it's all public. No black box, no "trust me."

Cloud Security Snapshot

Available for: Google Workspace • Microsoft 365

What it is: A focused, automated check of your cloud email and file platform, whether that's Google Workspace or Microsoft 365. It looks at six of the most common ways small businesses get exposed, and shows you exactly what it finds in plain English.

The Problem: Most small businesses run their entire company on Google Workspace or Microsoft 365 and have never once checked the security settings underneath it. Nobody looks until something goes wrong: an old employee's account still has access, a file got shared outside the company by accident, or an app someone connected two years ago still has the keys to your email.

The Solution: The Cloud Security Snapshot checks six areas that matter most on either platform: multi-factor authentication, inactive or disabled accounts, admin access, file sharing, connected third-party apps, and email forwarding rules. You get a short report ranking what it finds by severity, with a handful of concrete next steps, not a 40-page audit nobody reads.

The CastelGuard Difference: I built this tool myself, for both platforms, and ran each version against my own company's environment before I ever offered it to a client. I can walk you through every single thing it checks and why it matters, because I wrote the code that checks it.

Here's what you walk away with:

  • A plain-English PDF report, ranked by severity

  • 3 to 5 concrete fixes you can act on right away

  • Full transparency: I'll explain every finding, no jargon, including where a lower-tier license limits what a check can see

Prefer to run it yourself, or have your MSP run it? Both versions of the tool are open source. Full setup instructions for Google Workspace and Microsoft 365 are on GitLab: gitlab.com/jbisutti/castelguard

The Cloud Security Snapshot is the first of several tools I'm building for small businesses in the Mahoning Valley. Next up: a broader security posture dashboard for tracking your risk over time. If there's a specific check or tool you'd find useful, tell me on a call, I build these based on what actually helps.
