Microsoft 365 by Industry — Zero-Knowledge Backup & Audit

How zero-knowledge Microsoft 365 backup, audit and migration fits regulated industries — healthcare, legal, financial services, public sector, education, and tax & accounting.

Microsoft 365, matched to your industry

GTools.pro is a zero-knowledge Microsoft 365 toolkit: the vendor never sees plaintext, and the Desktop edition keeps backup, audit and migration data on the operator machine. For regulated sectors that maps directly onto the question that actually decides procurement — can a third party read our data? Below, the pages address each industry’s specific drivers with sourced framing. These pages are general information, not legal advice.

Industries covered

  • Healthcare & Life Sciences (Gesundheitswesen) — Back up, audit and migrate Microsoft 365 for hospitals and medical practices without a vendor ever being able to read patient data.
  • Law Firms & Legal (Kanzleien & Rechtsanwälte) — Microsoft 365 backup and migration for law firms where privileged client data never becomes readable to a third-party vendor.
  • Financial Services (Finanzdienstleister & Banken) — Microsoft 365 backup, audit evidence and migration for financial firms — DORA-aware ICT third-party risk minimisation with data the vendor cannot read.
  • Public Sector & Government (Öffentliche Verwaltung) — Microsoft 365 backup and audit for public bodies where data sovereignty is non-negotiable — the Desktop edition keeps everything on-premise.
  • Education (Bildungseinrichtungen) — Microsoft 365 backup and audit for schools and universities — pupil data protected, budgets respected, free for a single administrator.
  • Tax & Accounting (Steuerberater & Wirtschaftsprüfer) — Microsoft 365 backup and audit for tax advisors and auditors — mandant data the vendor cannot read, GoBD-friendly point-in-time evidence.

Limitations — what these pages are not

These are marketing pages describing how GTools.pro’s architecture maps onto common sector requirements. They do not assert certification against any named standard unless stated, and they do not replace your own data-protection, legal, or procurement assessment.

About the platform

This is a zero-knowledge toolkit. It helps IT admins, MSPs, security teams run their cloud safer. Use it inside a browser. Or install our Mac or Windows app.

Tenant secrets stay on your disk. We never store, log, or read them. Our server only sees billing metadata.

How it works

  1. You unlock a local vault with a passphrase. Argon2id stretches it.
  2. Tokens get sealed with XChaCha20-Poly1305 before any sync.
  3. X25519 protects shared keys. Ed25519 signs every action.
  4. Each operation runs against Graph from your device, not ours.
