An attempt to steal passwords, money or access through a message impersonating a trusted person or service.
It is one of the most common ways to compromise business email and accounts.
Business cybersecurity
Microsoft 365 security starts with accounts, email and MFA
Microsoft 365 is the communication center for many companies. Account takeover or phishing can quickly become an operational problem.
Key risk
Microsoft 365 as a risk center
In many companies, Microsoft 365 is the center of communication, documents and teamwork. Account takeover can mean access to email, files, contacts, invoices, customer data and further impersonation of an employee.
Practical context
Terms and information that make the decision easier
These short explanations help discuss risk without going too deep into technical detail.
An account with elevated permissions that can change settings, users and access to data.
Needs stronger protection because compromise gives broad control over the environment.
An independent copy of email, OneDrive, SharePoint or Teams data.
Helps recover data that account settings alone cannot restore.
Scope and approach
What to know before the next step
What we check
We start with the settings that have the greatest impact on account and email security.
- MFA for users and administrators
- administrator accounts and their permissions
- basic email settings and phishing protection
- permissions to data and groups
- Microsoft 365 data backup
- procedure for removing access after an employee leaves
Why a password alone is not enough
Phishing and password leaks make a single password too weak as protection. MFA, permission limitation and control of administrator accounts are the foundation of Microsoft 365 security.
Effect
The company gains better account control, lower risk of email takeover, more organized permissions and clarity on whether Microsoft 365 data is also protected by backup.
Who Microsoft 365 security is for
This service is for companies where Microsoft 365 has become the center of email, documents, teamwork and access to business services. The business problem appears when one compromised account can expose invoices, correspondence, customer files or enable further impersonation of an employee.
- companies using Exchange Online, OneDrive, SharePoint or Teams
- organizations unsure whether MFA is properly enforced
- companies after staff changes where access removal was not systematic
- companies preparing for an audit, cyber insurance, ISO 27001 or NIS2
When Microsoft 365 should be reviewed
A Microsoft 365 review is useful when the company does not know who has administrative rights, whether MFA covers important accounts, whether email is protected against phishing and whether data can be restored after deletion or an incident. The greatest risk often comes from default or historical settings that no longer have an owner.
Service scope
Aptigo reviews and organizes settings that directly affect account takeover, data loss and continuity of work.
- MFA for users, administrators and remote access
- administrator accounts, roles and excessive permissions
- email protection against phishing and impersonation
- permissions to data, groups and shared mailboxes
- access removal procedure after an employee leaves
- retention and backup of Microsoft 365 data
What we do not promise
We do not promise that Microsoft 365 will be immune to every phishing attack or that configuration alone replaces user awareness, backup and response procedures. The goal is to reduce the likelihood of account takeover, limit incident impact and clarify responsibility.
FAQ
Common questions
Does Microsoft 365 create backup by itself?
Microsoft provides service availability, but requirements for data recovery after deletion, error or incident should be assessed separately. In many companies, independent backup is needed.
Is MFA necessary for everyone?
It is best to treat MFA as a standard, especially for administrator accounts, email and people with access to important data.
Does Microsoft 365 need backup?
In many companies, yes. Microsoft provides service availability, but the company should separately assess data recovery after deletion, user error, ransomware or account takeover.
Is MFA enough?
MFA is a foundation, but it is not enough on its own. Permissions, administrator accounts, email security and access removal procedures also need to be controlled.
