Microsoft 365 Security Audit
for Your Business

Find the security gaps in your Microsoft 365 before hackers do. Get an 80+ point audit with prioritized fixes.

We’ll reach out within one business day with next steps.

Microsoft 365 runs more than 400 million business mailboxes worldwide. That makes it the biggest target in business email. Adelia Risk performs detailed Microsoft 365 security assessments that check every critical setting across your Exchange Online, SharePoint, OneDrive, Teams, and Entra ID environment. We identify what’s misconfigured and prioritize the fixes. Then we give you a clear roadmap to lock things down.

The Wrong Assumptions
Breach Companies

"We set it up correctly"

In a typical Microsoft 365 security audit, Adelia Risk finds 60-80+% of security settings misconfigured or left at defaults. IT teams are busy keeping things running. Business owners are focused on running their company. That means security settings get missed. One wrong setting is all it takes for a hacker to get in.

We audit dozens of Microsoft 365 environments a year. The “set it and forget it” assumption is always wrong.

Consider that hackers breached Microsoft’s own corporate tenant through a legacy test account that didn’t have multi-factor authentication. They then used OAuth apps to read corporate email. If Microsoft’s own environment had gaps, yours likely does too. And in 2023, attackers used a stolen signing key to forge access tokens and read government officials’ Exchange Online email for over a month before anyone noticed. A government review board later called the breach preventable.

"Microsoft handles security for us"

Microsoft secures the underlying platform. You’re responsible for how it’s configured. Conditional access policies, admin permissions, external sharing in SharePoint, email authentication, OAuth app consent settings. These are all YOUR responsibility. Microsoft provides the tools, but you have to use them correctly (either on your own or through our Microsoft 365 Security Management service).

This catches a lot of business owners off guard. Microsoft’s Shared Responsibility Model spells it out clearly, but the marketing makes it sound like they handle everything. They don’t.

"We're too small to be targeted"

Business email compromise doesn’t discriminate by company size. Hackers send millions of phishing emails and see who bites. If one of your employees clicks the wrong link, your size won’t save you. You won’t have a security team to catch it. That’s what makes small businesses attractive targets.

Microsoft 365 is the most-used business email platform in the world. Attackers build their tools and playbooks around it because that’s where the targets are. It doesn’t matter whether you have 15 employees or 1,500.

"We already use 2-factor authentication"

Two-factor authentication is one setting. We check 80+ more. Are your conditional access policies actually blocking risky sign-ins? Can users forward emails to external addresses? Are third-party apps accessing your SharePoint data through OAuth consent? 2FA is table stakes. It’s not a complete security program.

During a Microsoft 365 security audit, we’ve seen businesses with MFA enabled get compromised because everything else was wide open.

Microsoft 365 Is a Great Platform.
But It's Not Secure by Default.

Adelia Risk does Microsoft 365 security audits every week. It’s well-designed, reliable, and gives businesses powerful tools for email, file sharing, and collaboration. But Microsoft’s default settings prioritize convenience over security. That means your employees can probably share files externally without restriction, third-party apps may have access to your data through OAuth consent, and email spoofing protection is likely incomplete.

We see this constantly during Microsoft 365 security reviews. Businesses assume Microsoft has them covered, then we find a big list of fixes that need to be implemented.

  • Urgent: Fix these immediately
  • Easy: Low user impact, implement anytime
  • Moderate: May affect users, communicate first
  • High Impact: Requires planning and user training

Screenshots and Instructions

You won’t be guessing where to find settings. Every recommendation includes screenshots and step-by-step instructions for how to make the fix. Hand it to your IT team or follow along yourself.

Microsoft 365 Security Audit and Management
Questions Answered

Will you be able to see our emails and documents?

This is the first question everyone asks before a Microsoft 365 security audit, and the answer is ABSOLUTELY NOT. The Global Reader role we use gives us access to settings only. We cannot read your emails, view your documents, or access any of your data. We see configuration options, but not the content.

Typically 2-4 weeks from when you grant us access. The timeline depends on how quickly you can assign the Global Reader role and schedule the findings review. Most clients have their report within two weeks.

Nothing. Once you’ve granted access, we handle everything. You’ll hear from us when the report is ready to review. Clients tell us this is refreshingly hands-off.

We can do it for you. A lot of our clients don’t have dedicated IT staff, so we offer implementation services after the audit. We also offer our Microsoft 365 security management option, which includes annual audits, quarterly setting checks, 24/7 monitoring and more. We’ll handle the technical changes while you focus on running your business.

Microsoft releases so many updates that we’d recommend checking more often. But annually is the minimum to catch drift. Your business changes too: new employees, new tools, new processes. An annual audit catches configuration drift and makes sure new features are set up securely.

Many companies actually need more than annual audits. That’s why we also offer our Microsoft 365 security management service, which includes quarterly checks, advanced email protection, and more.

The audit is a point-in-time review. You get the report, implement the fixes, and you’re done until next year, for a one-time fee. The managed service adds continuous monitoring, quarterly checks, and advanced email protection for an ongoing service fee. If you want ongoing peace of mind without thinking about it, the Microsoft 365 Security Management plan is the way to go.

Good question. We monitor for suspicious sign-in activity, admin configuration changes, unusual mailbox access patterns, and security rule modifications. If something looks wrong, we alert you. Think of it as a security camera for your Microsoft 365 environment.
