Cloud Services / Microsoft 365
Microsoft 365 setup, identity security, permissions review, and secure configuration for the cloud environment your business runs on.
Who this service is for
Microsoft 365 management and security from NetFortress is for SMBs that run their business on M365 and need it configured, protected, and backed up properly, including the independent backup that Microsoft's shared-responsibility model leaves to you and the SPF, DKIM, and DMARC records that stop attackers spoofing your domain.
- Businesses already on Microsoft 365 that have never had a security review
- Teams migrating to M365 from another provider or an on-premises server
- Offices storing client files in SharePoint or OneDrive
- Companies whose employees work from multiple devices and locations
- Businesses that assume Microsoft backs up their data – under the shared-responsibility model, that is your side
Where Microsoft 365 goes wrong
Default settings favor ease of use over security, so most businesses run M365 with significant gaps without realizing it. Our Microsoft 365 security checklist walks through the same ground:
MFA not enforced on every account
One phished password gives an attacker mailbox access, and from there password resets for every system connected to that mailbox.
Open external sharing and mail forwarding
Client files and email can leave the organization silently, with no audit trail that anyone actually reviews.
Excessive admin role assignments
Every unnecessary admin account is a high-value target; compromising one can compromise the whole tenant.
No dedicated backup for M365 data
Accidental deletion, a departing employee, or ransomware can permanently erase mail and files that retention defaults do not preserve.
What a managed tenant looks like
- A tenant hardened against phishing, impersonation, and account takeover
- MFA and conditional access enforced without blocking day-to-day work
- Sharing and permissions that match how your business actually collaborates
- Independent backup of Exchange, SharePoint, OneDrive, and Teams
- The right licensing plan for your security needs, with no unnecessary spend
- A team coached to use the platform safely day to day

When was your tenant last reviewed?
A detailed Microsoft 365 security review shows exactly which default settings are exposing your business. It is the fastest way to know where you stand.
How we take over your Microsoft 365
Security review
We audit MFA coverage, admin roles, sharing policies, email security, and audit logging to map the gaps in your tenant.
Hardening and backup
The highest-risk settings are corrected, protection policies are deployed, and independent backup is put in place.
Ongoing management
We monitor the environment, manage licenses and policies, and support your team as the platform and your business evolve.
How ongoing management works
Alerts from your tenant – suspicious sign-ins, phishing detections, unusual mailbox rules – are reviewed and acted on rather than left in a dashboard. Policy changes are planned with you, tested, and documented, so security never arrives as a surprise to your team.
Day-to-day requests – a new starter's account, a sharing question, a licensing change – are handled as part of the service, so the platform keeps pace with how your business actually works.
What we manage
- Exchange Online
- SharePoint and OneDrive
- Microsoft Teams
- Entra ID and MFA
- Microsoft Defender for Office 365
- Conditional access policies
- Data loss prevention
- Microsoft 365 backup
Boundaries worth knowing
- Custom SharePoint development and app building are out of scope – we secure and manage the platform itself
- License costs are set by Microsoft; we optimize which plans you need, not their pricing
- The service covers Microsoft 365; other productivity platforms are supported as migration sources
Microsoft 365 management FAQs
Microsoft already secures the platform. Why do we need this?
Microsoft operates a shared-responsibility model: it keeps the platform running, while configuring it securely and protecting your data remain your responsibility. This service covers your side of that model.
Will MFA and new policies disrupt the team?
Rollouts are planned and communicated: policies are tested first, exceptions are handled deliberately, and your team is coached through the change. Security that blocks work gets bypassed, so we design controls people can live with.
Do we really need backup if Microsoft has retention?
Retention defaults are limited and are not a backup. Accidental deletion, a departing employee, or ransomware can put data beyond recovery. Dedicated backup for Exchange, SharePoint, OneDrive, and Teams keeps your records restorable.
Can you migrate us without downtime?
Migrations are planned so email and files stay available throughout the transition, with the cutover scheduled deliberately to avoid downtime and data loss.
Which Microsoft 365 plan should we be on?
It depends on your size and security needs. Licensing optimization is part of the service: getting the security features you need without paying for plans you do not use.
