Standard Approach vs. infoLib Enterprise Architecture
A side-by-side comparison of capabilities, recovery benchmarks, and operational security standards.
| Security Discipline | Default Unmanaged Microsoft 365 Tenant | infoLib Governed & Hardened Tenant |
|---|---|---|
| User Authentication | Basic passwords or legacy SMS MFA vulnerable to bypass | Zero Trust Conditional Access with push MFA & device compliance |
| Data Exfiltration | Unrestricted: employees can email customer lists externally | Strict DLP policies and Purview sensitivity labels prevent data leaks |
| Email Security | Standard spam filters blind to sophisticated BEC attacks | Defender for O365 with Safe Links, Safe Attachments & DMARC |
| Subscription Spend | Paying recurring monthly fees for inactive former employees | Continuous license optimization saving up to 30% on cloud spend |
| Regulatory Standing | Fails European NIS-2, ISO 27001, and GDPR compliance checks | Hardened Secure Score (>80%) with full audit trail documentation |

Microsoft 365 Governance FAQ
Everything you need to know about hardening your Microsoft 365 environment.
Why are default Microsoft 365 settings inadequate for business security?
Microsoft configures default tenant settings for maximum convenience, leaving critical protections (such as conditional access, data loss prevention, and strict audit logging) disabled. Without hardening, organizations remain exposed to credential theft and accidental data leaks.
How does infoLib lower our recurring Microsoft 365 subscription costs?
We perform comprehensive license utilization audits that identify unassigned licenses, active subscriptions assigned to departed staff, and over-provisioned premium tiers, reducing licensing waste by up to 30%.
What is Microsoft Secure Score and how do you improve it?
Microsoft Secure Score is a numerical benchmark (0-100%) measuring your tenant's security posture. Most unmanaged tenants sit below 40%. infoLib systematically addresses configuration gaps to lift your score above 80%.
How are company files protected on employee mobile phones?
We deploy Mobile Application Management (MAM) via Microsoft Intune. Corporate emails and documents are encrypted within protected app containers, preventing staff from copying corporate data into personal apps like WhatsApp.
Does Microsoft 365 Governance satisfy European NIS-2 requirements?
Yes. The NIS-2 directive mandates robust multi-factor authentication, incident logging, access control, and supply chain security—all of which are implemented and documented during our governance engagements.
How long does a tenant security hardening engagement take?
Our comprehensive security audit is completed within 3 to 5 business days, with remediation policies phased in over 1 to 2 weeks without disrupting daily employee productivity.
