What is a Microsoft 365 Security Review, and why every Perth business needs one
Microsoft 365 account compromises are the #1 cause of cybercrime losses for Australian businesses. An account compromise occurs when an attacker gains access to an employee’s Microsoft 365 account, using it to steal funds or data, and damage your reputation before you even know they’re there.
Our Microsoft 365 Security Review for businesses analyses six months of your Microsoft 365 tenant’s activity across Entra ID, Exchange Online, OneDrive for Business, SharePoint Online, and Microsoft Teams. It detects active intruders and attackers who are targeting your employees but haven’t broken through yet – so you can act before they do.
How it works
Three steps to a complete picture of your Microsoft 365 threat landscape
Step 1 – Collect six months of Microsoft 365 signals
We gather activity data from Microsoft Entra ID, Exchange Online, OneDrive for Business, SharePoint Online, Microsoft Teams, and Defender for Microsoft 365, building a complete baseline of your tenant’s behaviour across the period.
Step 2 – Filter noise from genuine threats
Classic signals like impossible travel and VPN logins are analysed carefully. While many are normal business activity, some mask active attackers operating from Australian or overseas IPs. We separate the two, and identify the real threats to your organisation.
Step 3 – Microsoft 365 breach detection
Signature-based tools miss low-and-slow, advanced attackers. We build a baseline of normal behaviour, and surface patterns that bypass Microsoft Defender and traditional email security that would otherwise remain invisible for months.
What you’ll get from us
Your Microsoft 365 security Report in plain-English, with actionable findings
Active attacker detection: The report identifies Microsoft 365 breaches, naming compromised accounts, how long the attacker had access, and exactly what they did (including emails read, files accessed, and malicious emails sent).
Full forensic timeline: Every attacker action is logged with timestamps, IP locations, and method of entry, including how they bypassed multi-factor authentication using AiTM (Attacker-in-the-Middle) phishing techniques.
Business impact assessment: The report measures real-world impact. This includes financial records accessed, sensitive files opened, and malicious emails sent to your contacts. These are categorised as Financial Risk, Data Theft, or Reputational Harm.
What should have happened: A side-by-side view shows where Ever Nimble’s real-time monitoring would have blocked the attack, at every stage, before any damage was done.
A clear next step: You get plain-English recommendations to stop the same attack patterns from succeeding again, so you can protect your Perth business. This includes the option to turn on ongoing support and continuous monitoring from Ever Nimble.
FAQs
Does the review process email contents?
No. The review only processes the metadata of your Exchange Online activity, including sender, recipient, timestamps, and routing information. Email body content is never read, accessed, or stored.
We have Microsoft Defender and email security. Are we still at risk of account compromise?
Yes. The majority of modern Microsoft 365 account compromises bypass Defender and email gateways entirely, arriving via trusted third-party app phishing, OAuth token theft, or logins from legitimate Australian IP addresses that your tools treat as safe.
How long does the Microsoft 365 Security Review take?
Typically 48 hours from initiation to a completed Scan Report. We’ll walk you through the findings in a short debrief call at a time that suits your team.
Do I need an admin account to initiate the review?
Yes, a Global Admin or Security Admin account is required to grant the read-only Microsoft Graph permissions the review needs. No data is modified during the process, and permissions can be revoked immediately after completion.
Is this suitable for Perth SMEs, or only enterprise?
The Microsoft 365 Security Review is designed for any Australian organisation running Microsoft 365, from 20 to 2,000 seats. Cyber criminals don’t discriminate by company size, and neither does our process.
