Over deze dienst
Is your Microsoft 365 tenant actually secure, or just running on defaults?
Most M365 breaches happen through default settings: legacy authentication bypassing MFA, unmonitored forwarding rules enabling invoice fraud, and standing Global Admin accounts creating massive risk.
I provide a measured, zero-downtime security audit and hardening service for your Microsoft 365 and Entra ID estate, lifting your Secure Score while keeping your business running.
What I Secure:
- Identity Protection: Enforce MFA via Conditional Access, permanently block legacy auth, and configure secure break-glass accounts.
- Anti-Spoofing & Email: Align SPF, DKIM, and DMARC. Enable Defender Safe Links and Safe Attachments.
- Privileged Access: Strip unnecessary Global Admin rights down to a least-privilege model.
- Data Defense: Restrict anonymous sharing links and mandate unified audit logging.
The 3-Phase Process:
- Audit: A read-only review against CIS Benchmarks.
- Harden: Staged, reversible changesyou approve every step.
- Verify: Live testing and a before/after Secure Score export.
Your Deliverables:
- Executive Findings Report (PDF)
- Step-by-step Remediation Plan
- Admin Runbook for your IT team

Veelgestelde vragen
What level of access do you need to my Microsoft 365 tenant?
For the initial Phase 1 audit, I strictly require a 'Global Reader' role. This is a read-only permission that allows me to evaluate your security posture without the ability to change any settings. If we proceed with the hardening phase, I will require a temporary 'Global Administrator' assignment d
Will these security changes cause downtime or lock my employees out?
No. Every configuration change is staged, tested, and carefully rolled out. For example, when we enforce Multi-Factor Authentication (MFA), I implement a registration grace period so your staff can configure their authenticator apps without being abruptly locked out of their daily workflows.
Do I need to buy expensive E5 licenses or third-party tools for this to work?
No. My security methodology is designed to maximize the defenses already included in your existing subscription (such as Microsoft 365 Business Premium or E3). I will not pressure you into buying third-party software. The goal is to properly configure the tools you are already paying for.
Can we revert a setting if it conflicts with one of our internal apps?
Absolutely. I document a clear rollback path for every policy applied during the hardening phase. We conduct per-role sign-in verification tests, and if a Conditional Access policy or legacy authentication block conflicts with a critical business process, it can be immediately reverted or scoped wit
How do I know the changes you make are actually effective?
I rely on measurable data, not estimates. Included in the final delivery is a before-and-after export of your Microsoft Secure Score, proving the direct impact of the applied hardening. You will also receive an Administrator Runbook documenting exactly what was changed and why.
