Microsoft 365 Security Review
Strengthen your Microsoft 365 environment with expert-led configuration analysis.
Why a Microsoft 365 Security Review Matters?
Microsoft 365 is at the heart of how modern organisations operate, powering email communication, document collaboration, file storage, and identity management. Its widespread adoption and deep integration into business processes make it a critical asset, but also a potential point of exposure if not properly secured.
Despite its robust native security capabilities, Microsoft 365 environments are often underutilised or misconfigured. Default settings may not reflect the unique requirements of your organisation, and unmanaged growth in users, devices, and third-party integrations can lead to blind spots, privilege creep, and increased risk.
Secon’s Microsoft 365 Security Review delivers a thorough, expert-led assessment of your current configuration. We examine your security policies, user access controls, and threat protection mechanisms in detail, ensuring they not only align with Microsoft’s best practice recommendations and CIS Controls, but also support your business goals and regulatory obligations.
Whether you’re looking to improve compliance, reduce your threat surface, or maximise your existing Microsoft 365 investment, this review offers the clarity and direction you need to move forward with confidence.
What’s included in a Microsoft 365 Security Review?
Configuration Assessment.
We conduct a focused review of your Microsoft 365 tenant to identify misconfigurations, security gaps, and opportunities for improvement across:
- Authentication & Access Controls
We assess MFA deployment, Conditional Access policies, and identity management practices to ensure access is secure and role-appropriate. - Email Security
We evaluate anti-phishing and anti-malware protections, including Defender for Office 365 settings, transport rules, and SPF/DKIM/DMARC records. - Data Loss Prevention (DLP)
We review DLP policies across Exchange, SharePoint, OneDrive, and Teams to ensure sensitive data is protected from unauthorised sharing. - Audit & Logging
We check that audit logging is active and configured to support incident response, compliance, and integration with security tools.
Risk-Based
Analysis.
Every identified issue or misconfiguration is assessed in context—based on the level of risk it poses to your users, data, and overall security posture.
Rather than just flagging technical concerns, we rank findings by their real-world impact and exploitability. This ensures that you can prioritise remediation efforts effectively, focusing first on the changes that deliver the greatest reduction in risk.
Comprehensive Reporting.
At the end of your Microsoft 365 Security Review, you’ll receive two well-structured reports designed to support both strategic decision-makers and technical teams:
- Executive Summary – A concise, accessible overview that outlines the scope of the review, key findings, and top-priority recommendations. Ideal for leadership and stakeholders looking for a clear understanding of current risk and next steps.
- Technical Findings Report – A detailed analysis of each issue identified, including affected configurations, risk severity, remediation guidance, and relevant Microsoft best practice references. Where appropriate, this includes supporting screenshots or evidence.
Together, these documents provide a practical, prioritised roadmap to help your organisation improve its Microsoft 365 security posture with confidence and clarity.
Benefits of a Microsoft 365 Security Review.
Identify Vulnerabilities.
We uncover overlooked misconfigurations, excessive access, and legacy settings that attackers exploit.
By benchmarking your environment against Microsoft and CIS best practices, we highlight risks automated tools often miss, giving you a clearer view of your true exposure.
Ensure Compliance.
We assess your setup against key frameworks like CIS, ISO 27001, and NIS2, helping you stay audit-ready and compliant.
You’ll understand where your configurations fall short and how to align with governance, risk, and regulatory standards, without the guesswork.
Optimise Security Investments.
We help you get more from your existing Microsoft 365 licensing, highlighting underused features, eliminating inefficiencies, and recommending cost-effective improvements.
The result? Stronger security, without unnecessary spend.
Tailored Security Posture Insights.
Generic scores don’t tell the full story.
We provide contextual insights based on your actual usage and structure, so you can prioritise changes that will have the biggest impact and track how those changes improve your posture over time.
Dark Web
Monitoring.
We check for leaked credentials and compromise indicators tied to your domain, giving you early warning of risks that could lead to account breaches.
It’s a critical layer of visibility beyond your Microsoft 365 perimeter.
Uncover risks, unlock value, and take control of Microsoft 365.
Our Microsoft 365 Security Review goes beyond surface-level checks. It provides a tailored analysis of your configurations, highlights real security gaps, and offers clear, prioritised steps to improve your security posture and compliance readiness.
