Before joining Regroove, I served as a Signals Officer in the Canadian Army Reserves. Military security protocols are thorough, rigorous, and deeply ingrained in how everyone operates. Your organization does not handle national security, but the underlying principles translate directly to protecting business data. Here are the three that matter most.
All Information Is Accessed on a Need-To-Know Basis
In the military, having a higher clearance level does not automatically grant access to everything. Access requires a legitimate reason, regardless of rank. Organizations can apply the same principle through least privilege access, restricting both data access and administrative capabilities to only what each employee needs for their specific role.
In Microsoft 365, this looks like:
- Azure Privileged Identity Management (PIM), which allows time-based, approval-based access to sensitive functions rather than permanent elevated permissions
- Dedicated admin accounts separate from standard user accounts, so administrators log into a privileged account only when performing administrative tasks
- SharePoint and Teams sites treated as security zones with clearly defined access parameters
The U.S. Department of Defence pioneered the concept of least privilege in modern cybersecurity practice. It remains one of the most effective controls available.
All Information Should Be Labeled With Its Classification
Every document should have a classification that reflects how sensitive it is. This determines what protections apply, who can access it, and where it can be stored. Over-classification creates unnecessary friction. Under-classification creates unacceptable risk.
Microsoft 365 sensitivity labels address this directly. Labels classify and protect files, emails, folders, and document libraries. They can enforce encryption, apply access controls, add watermarks, and trigger retention policies. AI can automatically assign labels based on content analysis, reducing the burden on individual users.
Everyone Is Responsible for Security All the Time
This is the most important cultural element and the hardest to maintain. Security awareness cannot live only in an annual training session. It needs to be reinforced through all-hands meetings, newsletters, and regular conversation.
The statistics are sobering. Ninety percent of data breaches result from phishing attacks that target end users. Technology controls help, but they are not sufficient on their own.
Protective technologies that support a security-minded culture include:
- Multifactor authentication: MFA prevents 99.9 percent of all incoming attacks. This is not an exaggeration. It is the single highest-impact security control most organizations can implement.
- Device management: Microsoft Intune restricts access to authorized devices and enables remote data wiping if a device is lost or compromised.
- Attack simulation training: Sending realistic phishing simulations to your team identifies who is vulnerable and provides targeted training in context, which is far more effective than general security awareness content.
Creating an environment where employees feel safe reporting security mistakes is equally important. People who are afraid of punishment for clicking the wrong link will hide mistakes rather than report them, which makes breaches worse.
Getting a Security Assessment
Regroove provides security assessments that evaluate your Microsoft 365 environment against current best practices and produce a prioritized roadmap for improvement. If you are not sure where your organization stands, a security assessment is the logical starting point.
