Microsoft 365 security for businesses
Microsoft 365 security tailored to your environment
Microsoft 365 is at the heart of day-to-day work for many businesses. Emails, files, meetings, collaboration and devices are closely connected. This centralization improves productivity but it also requires a consistent approach to security.
Groupe SL helps you review and strengthen the security of your Microsoft 365 environment. We focus on the most significant risks to your organization and help you implement measures tailored to your users, data and priorities.
Start by understanding your risks
Every business uses Microsoft 365 differently. A small team that communicates primarily by email does not have the same needs as an organization that makes extensive use of SharePoint, Teams, OneDrive and mobile devices.
An assessment provides a clear picture of your current environment and helps prioritize improvements. It can highlight:
- Accounts and privileges that require particular attention
- Authentication methods currently in place
- File sharing and access to collaboration spaces
- Email settings and phishing risks
- Devices that access organizational data
- Issues that should be addressed first based on your level of risk
A clear process
Our approach is tailored to your organization’s needs, one step at a time.
Define the scope and priorities
Together, we determine which applications, user groups and issues should be addressed first to keep the assessment practical and relevant.
Assess practices and settings
We review relevant configurations and practices, including accounts and privileges, authentication methods, file sharing, email settings and devices.
Present risks and recommended actions
You receive our findings and recommended actions in a practical order, along with the rationale behind each one. This gives you a clear understanding of what needs to be done and why.
Implement the selected improvements
We help you implement the selected changes while minimizing the impact on your teams’ day-to-day work.
Maintain good security practices
Your environment evolves. We help you maintain good practices as new tools, use cases and users are added.
Security that covers your entire environment
Microsoft 365 security goes beyond using a strong password. It depends on how identities, emails, devices and data are protected and managed every day.
Our approach covers four essential areas, which we adapt to the size of your organization and the way you use Microsoft 365.
Four essential areas
Each area can be assessed and strengthened separately based on your priorities and level of maturity.
Identities and access
We review account access, administrative privileges and authentication methods. The goal is to reduce risks related to compromised accounts and access permissions that no longer reflect users’ actual needs. See also our Identity Security page.
Email and collaboration
Email remains a common entry point for phishing and fraud. We help you review the appropriate protections for your email environment, sharing practices and collaboration spaces. See also our Email Security page.
Devices and workstations
Computers and mobile devices that access Microsoft 365 need to be considered as part of your security posture. We can help you establish consistent measures to reduce exposure for your users and data. See also our Endpoint Security page.
Data and files
Your teams need to collaborate without making sensitive information more accessible than it should be. We review access permissions, sharing and file management practices to help improve control. See also our Data Security page.
How secure is your Microsoft 365 environment?
A targeted assessment can quickly identify which settings, access permissions and practices should be addressed first without disrupting your teams.
Microsoft 365 security and Copilot adoption
The introduction of Copilot in Microsoft 365 makes access and file management even more important. Copilot relies on users’ existing permissions. Information that is shared too broadly can therefore become easier to find.
Before a deployment or Copilot training, a Microsoft 365 security review can help ensure that access permissions, collaboration sites and sensitive content are managed appropriately.
Review access before deployment
File access, SharePoint sites, Teams and external sharing: a targeted review helps prevent unpleasant surprises when users first start working with Copilot.
Train your teams with a clear framework
Once the environment is ready, your teams can adopt Copilot with realistic expectations and clear usage guidelines that everyone understands.
Tell us about your current environment and the challenges you want to address. We’ll help you determine the most relevant next steps.
Frequently asked questions about Microsoft 365 security for businesses
Do we need to replace our Microsoft 365 environment?
No. The goal is to improve the security of the environment you already use based on your tools, licences and priorities.
Do we need an assessment even if we use multifactor authentication?
Multifactor authentication is an important security measure but it does not cover email, devices, file sharing, administrative privileges and other aspects of Microsoft 365 security on its own.
Can you help us prioritize improvements?
Yes. A good approach starts with the areas that present the greatest risk or will have the greatest impact on protecting your environment.
Can this approach support our compliance obligations?
Technical controls are part of good data management but compliance also depends on your legal obligations, processes and governance. We can support the IT component and collaborate with other stakeholders in your organization.
