In today’s threat landscape, one of the biggest challenges facing small and medium-sized businesses (SMBs) isn’t just the volume or complexity of cyber threat, it’s knowing where they’re most vulnerable and how to take meaningful action.
Many organizations invest in a patchwork of security tools, often without a clear picture of how those tools interrelate, or whether their controls are actually effective. This is where the Microsoft Cyber Security Assessment Tool (CSAT) offers immense value.
CSAT is not just another scanner or reporting dashboard. It’s a comprehensive, automated assessment tool designed to give businesses a clear, fact-based view of their security maturity across Microsoft-based environments including Office 365, Azure, and endpoint infrastructure. More importantly, it turns technical data into actionable risk insights, helping businesses make informed decisions about where to prioritize their limited security budgets.
In this post, we’ll unpack what the Microsoft CSAT is, how it works, and why it should be a key part of any organization’s cyber security improvement strategy.
1. What Is the Microsoft Cyber Security Assessment Tool (CSAT)?
The Cyber Security Assessment Tool (CSAT) is a solution designed to assess the technical and organizational security posture of Microsoft-centric environments. Developed by QS Solutions in partnership with Microsoft, CSAT combines automated technical scans with a structured governance questionnaire to deliver a comprehensive report on an organization’s security maturity.
The goal of CSAT is simple:
- Identify vulnerabilities and gaps in your technical controls and security config policies
- Benchmark your current maturity against recognized security frameworks, and
- Prioritize remediation activities based on real-world risk.
It’s ideal for SMBs, enterprises, and IT service providers that need to:
- Understand their security status across Microsoft 365 and Azure,
- Demonstrate compliance with frameworks like CIS
- Build an actionable cyber security roadmap without lengthy manual audits.
2. Why Does Security Maturity Assessment Matter?
Most organizations today face two common problems:
- Too many alerts, too little clarity. Even well resourced security teams struggle to filter noise from genuine risk.
- Security investment without strategic alignment. Businesses often buy tools without a clear sense of whether they’re mitigating the most important threats.
Assessing your security maturity helps cut through that confusion. By understanding where you stand today, and what best practices look like, you can:
- Rationalize your security stack,
- Focus effort and budget where it matters most,
- Demonstrate progress to stakeholders and regulators, and
- Prepare for future audits or certifications.
3. What Does CSAT Assess? A Deep Dive
CSAT is designed to be both thorough and efficient. It evaluates your organization from two primary perspectives:
A. Technical Security Posture
Using secure, read-only APIs and agents, CSAT scans your Microsoft environment to gather configuration, compliance, and usage data across:
Endpoints
Scans both workstations and servers, identifying:
- Patch status
- Antivirus coverage
- Local administrator accounts
- Firewall settings
- Windows Defender status
Local Active Directory and/or Azure Active Directory
Identifies risks in:
- User account hygiene (e.g., stale or orphaned accounts)
- Password policies
- Group memberships
- Privileged access assignments
Microsoft 365 Tenant
Analyzes:
- Mailbox permissions
- External sharing configurations
- MFA adoption
- Secure Score alignment
- Exchange Online, SharePoint Online, OneDrive, Teams security settings
Azure Tenant and Resources
Scans:
- Azure subscription security settings
- Network configurations (NSGs, public IPs, etc.)
- Resource policies and compliance with best practices
- Identity and access controls for cloud services
B. Organizational Controls & Governance
CSAT also includes a structured questionnaire aligned to the Center for Internet Security (CIS) Controls, which evaluates:
- Security policies
- Incident response readiness
- Employee awareness training
- Vendor and third-party risk
- Data classification and privacy governance
This ensures you’re not only looking at technical controls, but also the people and process factors that are often overlooked in purely automated assessments.
4. What Does the Output Look Like?
At the end of the assessment, CSAT provides:
A Security Maturity Score
This score is mapped to your organization’s alignment with the CIS framework and Microsoft best practices. It gives you a clear, quantifiable benchmark.
A Prioritized Action Plan
Rather than dumping a list of issues, CSAT prioritizes remediation steps based on:
- Risk impact
- Business criticality
- Ease of implementation
- Compliance relevance
This helps IT leaders plan improvements in phases, focusing on the highest risk first.
Visual Dashboards
Interactive dashboards help stakeholders, technical and non-technical alike, understand current weaknesses and track improvements over time.
5. Use Cases: Who Should Use CSAT and Why?
Small and Medium Businesses (SMBs)
For resource-constrained businesses, CSAT is an excellent entry point to identify gaps and start building a cyber resilience strategy. It helps SMBs:
- Justify investments in MFA, patching, or EDR tools,
- Prepare for cyber insurance assessments,
- Align with the UK’s Cyber Essentials or ISO 27001 certification pathways.
Managed Service Providers (MSPs)
MSPs can use CSAT to:
- Deliver structured security assessments to clients,
- Offer remediation services based on prioritized outputs,
- Prove value with before and after maturity scores.
Enterprises Undergoing Cloud Transformation
Organizations migrating to Microsoft 365 or Azure can use CSAT to:
- Audit misconfigurations during transition,
- Identify legacy risks,
- Improve compliance readiness in cloud-native environments.
6. CSAT vs Microsoft Secure Score: What’s the Difference?
While Microsoft Secure Score provides helpful insights into tenant-level security configurations, it has a narrower focus:
- Primarily centered on Microsoft 365,
- Measures feature adoption more than actual risk posture,
- Lacks governance-level assessment.
CSAT complements Secure Score by:
- Including endpoint and on-premises Active Directory data,
- Assessing Azure cloud workloads,
- Evaluating governance, awareness, and policy gaps,
- Producing a risk-prioritized plan, not just a usage score.
7. Compliance and Reporting Benefits
With GDPR, Cyber Essentials Plus, and ISO 27001:2022 placing greater emphasis on accountability, CSAT helps organizations:
- Demonstrate a commitment to continuous improvement,
- Produce defensible risk assessments,
- Guide remediation with traceable outputs.
For UK-based organizations, this is particularly important in the context of the NCSC’s Secure by Design principles and the upcoming Cyber Security and Resilience Bill.
8. Getting Started with CSAT
Implementation is straightforward:
- You deploy lightweight agents or connect APIs via secure, read-only credentials.
- The scan runs in the background and takes minimal time.
- Questionnaire completion usually takes a few hours with relevant stakeholders.
- Within days, you receive a full assessment and tailored action plan.
It’s often run as a one-time audit, but best practices recommend re-running CSAT quarterly or biannually to track improvement and maintain a current view of your security posture.
