Security defaults or basic MFA, legacy auth often open
Microsoft 365 Security Hardening Services in Dubai, UAE & USA
Most Microsoft 365 tenants are not breached through clever exploits. They are breached through default settings nobody changed.
M365 Enterprise Hub delivers Microsoft 365 security hardening services for organizations in Dubai, across the UAE and in the USA. We review your tenant against the CIS Microsoft 365 Foundations Benchmark and Microsoft Secure Score, then fix what matters first.
You get a hardened tenant, a dated evidence pack and a baseline that stays in place. Hardening is one part of our wider cyber security services.
What Is Microsoft 365 Security Hardening?
Microsoft 365 security hardening is the process of changing tenant, identity, email, device and data settings from their defaults to a secure, documented baseline.
It closes the gaps attackers use most: legacy authentication, weak MFA, open external sharing, missing email authentication and too many admins.
A hardening project is not a product purchase. It uses the licences you already pay for, such as Microsoft 365 Business Premium, E3 or E5, and makes them work as intended.
Security Hardening Areas We Cover
We harden every layer of the tenant, in the order that removes the most risk first.

Why Secure Score Alone Does Not Mean Secure
Secure Score rewards actions, not outcomes. A tenant can score 70% and still allow legacy sign-ins for a service account.
We map each finding to real attack paths, such as password spray, consent phishing and mailbox takeover. Then we fix the settings that break those paths first.
Every change is tested in a pilot group before it reaches all users, so hardening does not lock anyone out.
Our Microsoft 365 Hardening Services
Delivered as a fixed-scope project, with optional monthly drift monitoring afterwards.
01Tenant Security Assessment
A full review against the CIS benchmark, Secure Score and Microsoft best practice, with every finding ranked by risk.
02Prioritised Remediation
We implement the fixes in your tenant, starting with identity and email, using pilot rings and change records.
03Baseline Documentation
A written security baseline covering each setting, why it is set and who owns it, ready for audits.
04Drift Monitoring & Review
Monthly checks that catch settings changed back, new admins and new risky apps, with a short report.
Hardening Gaps We Close
These issues appear in almost every tenant we review in the UAE and the USA.
- Legacy authentication still allowed, bypassing MFA
- More than five permanent Global Administrators
- No DMARC enforcement, so your domain can be spoofed
- Anyone links and guest access enabled with no expiry

Default Tenant vs Hardened Tenant
| Area | Default Tenant | Hardened by M365 Enterprise Hub |
|---|---|---|
| Sign-in | Conditional Access, phishing-resistant MFA, legacy auth blocked | |
| Admin Access | Several standing Global Admins | Least privilege roles with just-in-time elevation |
SPF only, DMARC missing or at p=none | SPF, DKIM and DMARC enforced, Defender policies tuned | |
| Evidence | No record of what was changed or why | Documented baseline and dated Secure Score history |

Microsoft 365 Security Hardening FAQs
It is the process of changing Microsoft 365 settings from their defaults to a secure, documented baseline. It covers identity, email, devices, data and admin access.
A typical tenant takes two to six weeks. The assessment takes about one week, and staged remediation takes the rest, depending on user count and change windows.
Not if it is done in stages. We test each change on a pilot group first, communicate it in advance and keep a rollback plan ready.
No. Most hardening uses Business Premium or E3 features. Some controls, such as Privileged Identity Management, need Entra ID P2 or E5.
It is a free, consensus-based checklist of recommended Microsoft 365 security settings published by the Center for Internet Security. We use it as one of our review baselines.
Yes. A documented baseline supports ISO 27001, NIST CSF, SOC 2 and UAE regulations. See our compliance services for full audit support.
Yes. We work remotely across the UAE and the USA, with on-site support in Dubai when needed.
