MICROSOFT 365 SECURITY
Is your Microsoft 365 environment properly protected?
Microsoft 365 sits at the centre of your business - email, files, identities, devices, collaboration and access to critical information. But having Microsoft 365, or simply enabling MFA, does not mean the environment is properly secured.
OmekaTech helps businesses review, configure, strengthen and manage Microsoft 365 security. We identify the gaps, explain the risks clearly and implement practical improvements without making everyday work unnecessarily difficult.

THE BUSINESS CHALLENGE
Microsoft 365 can appear secure while important gaps remain
Microsoft provides a powerful set of security capabilities, but those capabilities still need to be licensed appropriately, configured correctly and reviewed over time.
Many businesses rely on default settings, basic MFA and assumptions made during the original Microsoft 365 setup. As users, devices and applications change, weaknesses can develop around administrator access, authentication, email, sharing, devices and third-party applications.
Identity and administrator risk
Excessive administrator privileges, weak authentication controls, old accounts and unreviewed sign-in methods can provide attackers with opportunities to gain or retain access.
Email and account compromise
Phishing, impersonation, malicious links, unsafe attachments and unusual mailbox activity can place business communications, customers and payments at risk.
Unmanaged devices and information
Business information may be accessed from personal or poorly managed devices without appropriate security, compliance or data-protection controls.
HOW OMEKATECH HELPS
A coordinated approach to Microsoft 365 security
OmekaTech looks beyond individual settings and products. We review how identities, email, devices, applications, data and administrative access work together across the business.
Microsoft 365 security assessment
We review the current tenant configuration, licences, administrator roles, authentication methods, security policies, devices, applications and areas requiring further investigation.
We explain findings in clear business language and prioritise them by risk, impact, and urgency.
Identity and access protection
We strengthen how users and administrators access Microsoft 365 through appropriate MFA, Conditional Access, dedicated administrative accounts, session controls and sign-in policies.
The objective is to reduce unauthorised access while preserving a practical experience for legitimate users.
Email and collaboration security
We review and configure appropriate protections for Exchange Online, SharePoint, OneDrive and Teams, including anti-phishing controls, impersonation protection, Safe Links, Safe Attachments, external sender identification and sharing settings.
Device, endpoint and data protection
Where licensing and business requirements allow, we use Microsoft Intune and Defender for Business to manage devices, establish security baselines, improve endpoint protection and reduce the risk of business data being accessed from unsafe devices.
We also review backup, retention and information-protection requirements rather than assuming Microsoft 365 alone provides a complete recovery strategy.
BUSINESS BENEFITS
What stronger Microsoft 365 security means for your business
Reduced risk of account compromise
Stronger authentication, access policies and administrative controls make it more difficult for an unauthorised person to gain or retain access.
Better protection for business information
Email, files, devices and collaboration services are managed as connected parts of the same environment rather than isolated products.
Greater control over devices and access
The business gains clearer control over which users and devices can access company information and under what conditions.
Clearer management visibility
Leadership receives a more understandable view of the current security position, priority risks and improvements requiring attention.
OUR APPROACH
Clear steps towards a stronger Microsoft 365 environment
1
Understand
We identify how the business uses Microsoft 365, what information it depends on, how staff work and where management requires greater confidence.
2
Assess
We review the Microsoft 365 environment, licences, identities, administrator access, authentication, email protection, devices, applications, sharing and relevant security information.
3
Improve
Agreed recommendations are implemented in a controlled order. Important changes are tested and communicated to reduce unnecessary interruption to staff.
4
Review
Security is reviewed as users, devices, applications, Microsoft services and business requirements change. The objective is ongoing improvement rather than a one-time configuration exercise.
MICROSOFT 365 RECOVERY AND HARDENING
From lost administrative control to a stronger Microsoft 365 environment
The Challenge:
A business lost legitimate administrative access to its Microsoft 365 environment following the compromise of a privileged account. The incident affected access to the systems and clinical business information the organisation depended on.
A password reset alone would not have been sufficient. An attacker with privileged access may create additional accounts, authentication methods, forwarding rules, permissions, applications or active sessions that continue working after the original password is changed.
The OmekaTech Response:
OmekaTech worked through the Microsoft recovery process to restore legitimate administrative control.
Following recovery, the environment was reviewed for additional or hidden methods of access. Security was then strengthened through Microsoft 365 Business Premium, Conditional Access, MFA, email protection, Microsoft Defender and improved administrative controls.
The Outcome:
The business regained control of its Microsoft 365 environment and access to its critical information.
Its Microsoft Secure Score increased from approximately 25% to 65%, providing a measurable indication of the security improvements completed.
25% → 65%
Microsoft Secure Score improvement
Administrative control restored
Legitimate access recovered following compromise
Business Premium protections implemented
Identity, email, endpoint and administrative security strengthened
Important note: Microsoft Secure Score is an improvement measure. It should not be interpreted as a guarantee that an organisation cannot experience a security incident.
FREQUENTLY ASKED QUESTIONS
Questions about Microsoft 365 security
Clear answers to common questions from business owners and leadership teams.
Isn’t Microsoft 365 already secure?
Microsoft operates and protects the underlying Microsoft 365 cloud services, but every organisation is responsible for how its users, administrators, authentication methods, devices, applications, sharing settings and security policies are configured.
A capable platform can still contain significant weaknesses if the available controls have not been configured appropriately or reviewed over time.
Is MFA enough to protect Microsoft 365?
MFA is an essential security control, but it is not a complete Microsoft 365 security strategy.
Security should also address administrator privileges, Conditional Access, legacy authentication, device compliance, email protection, application permissions, session controls, data sharing, monitoring and recovery.
Do we need Microsoft 365 Business Premium?
Business Premium is often the recommended foundation for small and medium businesses that need stronger Microsoft 365 security and device management.
It includes Microsoft Entra ID P1, Intune, Defender for Business and Defender for Office 365 Plan 1. However, the appropriate licence depends on the organisation’s users, devices, security requirements and existing subscriptions.
OmekaTech reviews the current licensing position before recommending changes.
What does a Microsoft 365 security review include?
The review may cover licences, users, administrator roles, MFA, Conditional Access, authentication methods, sign-in activity, email protection, mailbox rules and forwarding, application permissions, devices, sharing, security policies, audit information, retention and backup considerations.
The final scope depends on the environment and the level of review required.
Can OmekaTech work with our existing IT provider or internal IT team?
Yes. OmekaTech can work alongside an existing IT provider or internal technology team where responsibilities, access and expectations are clearly agreed.
The objective is to strengthen the business’s Microsoft 365 security without creating unnecessary duplication or conflict.
Will security changes interrupt our staff?
Some security improvements may require users to sign in again, register MFA, update applications or enrol devices.
OmekaTech plans and tests material changes where practical, communicates expected impacts and avoids introducing multiple major changes without appropriate preparation.
Does Microsoft Secure Score prove that we are secure?
No. Microsoft Secure Score is a useful way to measure configuration improvements and identify recommended actions, but it is not proof that an organisation is secure and it does not guarantee that a breach cannot occur.
The score should be considered alongside the organisation’s risks, licences, devices, business processes and other security controls.
Does Microsoft 365 include a complete backup?
Microsoft provides service availability, retention and recovery capabilities, but these should not automatically be treated as a complete independent backup strategy.
Backup requirements should be reviewed against the organisation’s operational, legal, retention and recovery needs. Where appropriate, OmekaTech can recommend and manage an independent Microsoft 365 backup solution.
