Microsoft 365 has become the productivity platform of choice for many financial advisors, wealth management firms, CPA firms, and insurance agencies.
Email, Teams, SharePoint, OneDrive, and cloud collaboration have made it easier than ever to work securely from virtually anywhere.
But one question continues to come up:
Is Microsoft 365 secure enough by itself?
The short answer is yes—with the right configuration.
Out of the box, however, many organizations leave important security features disabled or only partially configured.
Microsoft 365 Provides a Strong Foundation
Microsoft invests billions of dollars annually into cybersecurity.
The platform includes features such as:
- Multi-factor authentication (MFA)
- Encryption
- Spam and malware filtering
- Identity protection
- Secure cloud storage
- Compliance tools
These features provide an excellent starting point.
However, firms should still understand that Microsoft 365 security is part of a broader cybersecurity strategy. The NIST Cybersecurity Framework is a helpful resource for organizing cybersecurity practices around risk identification, protection, detection, response, and recovery.
Where Many Firms Fall Short
Buying Microsoft 365 does not automatically mean your environment is secure.
Common gaps include:
Multi-Factor Authentication Not Enabled
Passwords alone are no longer enough.
Without MFA, stolen credentials can allow attackers direct access to email and client information.
Excessive User Permissions
Employees often have more access than necessary.
Limiting permissions reduces security risk if an account becomes compromised.
Financial firms should also review vendor and third-party access. For banks and regulated organizations, vendor risk management requirements can help guide how outside providers and service partners should be reviewed.
Poor SharePoint and OneDrive Configuration
Documents containing sensitive client information should have appropriate sharing controls.
Public links and unrestricted sharing increase unnecessary risk.

No Conditional Access Policies
Conditional Access helps control:
- Device access
- Geographic login restrictions
- Risk-based authentication
These controls significantly strengthen security.
Best Practices
Financial firms should regularly review:
- MFA status
- User permissions
- Email security
- Device management
- Backup strategy
- Security monitoring
Technology evolves quickly, and security settings should evolve with it.
