What an Office 365 Security Assessment Covers
Identity and Access Security Analysis
Your assessment evaluates Entra ID configuration, Multi-Factor Authentication coverage, Conditional Access policies, and Privileged Identity Management settings. Our engineers identify users and admins without MFA, review legacy authentication risks, and analyze risky sign-in patterns. Guest access permissions and B2B collaboration security are examined against enterprise best practices developed from 84 Fortune 500 M365 deployments.
Email and Communication Security Review
Defender for Office 365 configuration is assessed for effectiveness against phishing, malware, and spam threats. Safe Attachments, Safe Links, and email authentication protocols including SPF, DKIM, and DMARC are evaluated. Mail flow rules, transport policies, and quarantine management are reviewed to identify security gaps and false positive patterns that impact productivity.
Data Protection and Compliance Evaluation
Data Loss Prevention policies, sensitivity labels, and retention policies are analyzed for coverage and effectiveness. External sharing controls, encryption configuration, and Compliance Center settings are reviewed. Our assessment maps your current controls to regulatory requirements including HIPAA, PCI-DSS, SOC 2, and GDPR to identify compliance gaps and remediation priorities.
Collaboration Security Assessment
Teams security settings, SharePoint site-level permissions, and OneDrive sharing controls are evaluated. Guest access policies, external collaboration rules, and app permissions are assessed for risk. OAuth consent configurations and information barriers are reviewed to ensure collaboration security aligns with your organization’s risk tolerance.
Microsoft Secure Score Analysis
Current Secure Score is evaluated and benchmarked against industry peers. Improvement actions are prioritized by security impact and implementation effort. Historical trending reveals score progression and regression patterns. Control mapping aligns recommended actions to compliance frameworks, creating a roadmap for measurable security improvement.
Endpoint Security Integration
Intune compliance policies and Defender for Endpoint integration are assessed. Device enrollment, compliance baselines, and conditional access integration are reviewed. Endpoint security gaps that create identity or data protection vulnerabilities are identified with remediation guidance.
Why Choose US Cloud for M365 Security Assessment
30-50% Guaranteed Savings vs Microsoft Assessment Services
Our M365 security assessment delivers equivalent or greater depth than Microsoft consulting services at guaranteed savings of 30% to 50%. Clients receive comprehensive evaluation without premium consulting markups. The same expert engineers who conduct assessments can implement recommendations, eliminating costly knowledge transfer and duplicate discovery phases.
Assessment-to-Implementation Continuity That Competitors Cannot Match
Most security consulting firms assess and walk away. US Cloud engineers who evaluate your M365 environment can implement the remediation roadmap. No handoff delays, no re-learning your configuration, no knowledge loss. Assessment insights become action within days, not months. Optional 24/7 ongoing monitoring means security improvement continues beyond implementation.
Benchmarked Against 84 Fortune 500 M365 Deployments
Your security posture is compared to real-world enterprise configurations, not generic checklists. Recommendations reflect threat patterns and best practices from supporting Fortune 500 and Global 2000 enterprises across industries. This benchmarking identifies risks that automated tools and generic assessors miss.
Microsoft Specialization vs Generic Security Consultants
US Cloud engineers average 14+ years of Microsoft experience, many as ex-Microsoft employees. 100% of our focus is on Microsoft technologies. Generic security firms lack this depth in M365 architecture, licensing implications, and Microsoft-specific threat landscape. Our engineers resolve M365 cloud tickets over 77% of the time without escalation.
Financially-Backed Response Guarantees
Critical findings during assessment receive <15 minute response, backed by financial SLAs. Microsoft consulting provides targets, not guarantees. This speed ensures security risks are addressed immediately, not queued behind other engagements. Clients experience the same rapid response during implementation and optional ongoing support.
The ONLY 100% Dedicated Microsoft Support Specialist
US Cloud is Gartner-recognized as the only independent third party providing a legitimate, full replacement for Microsoft Premier and Unified Support. 100% of our revenue comes from Microsoft support and security services. We built our technical, legal, and business structures specifically for Microsoft enterprises. This singular focus delivers unmatched depth in M365 security assessment and remediation.
Our M365 Security Assessment Process
Phase 1: Discovery and Planning
Assessment scope is confirmed with stakeholders and compliance requirements are identified. Our team collects documentation, configures environment access, and conducts a kickoff meeting to align timeline and expectations. This phase typically completes within one week, establishing clear objectives and success criteria for the evaluation.
Phase 2: Technical Assessment and Configuration Analysis
Automated security scanning is combined with manual configuration review across identity, email, data protection, and collaboration domains. Secure Score is evaluated and benchmarked. Compliance control mapping begins. Our engineers analyze threat landscape patterns specific to your industry, drawing from experience supporting 750+ clients across sectors. This phase spans two weeks of intensive evaluation.
Phase 3: Analysis, Risk Prioritization, and Remediation Planning
Findings are consolidated, validated, and scored by risk level. Remediation effort is estimated for each finding. Quick wins that deliver immediate security improvement are identified. Strategic initiatives requiring longer timelines are planned. This analysis phase completes within one week, producing prioritized recommendations ranked by risk reduction per implementation hour.
Phase 4: Reporting, Roadmap Delivery, and Stakeholder Presentation
Executive summary, technical findings documentation, and remediation roadmap are developed. Deliverables include compliance mapping if regulatory frameworks were specified. Stakeholder presentation walks through findings, risk priorities, and recommended actions. Implementation planning and quote are provided if requested. This reporting phase completes within one week.
Optional Phase 5: Implementation Support and Ongoing Monitoring
The same engineers who assessed your M365 environment implement the remediation roadmap. Configuration changes and policy deployments are validated through re-assessment. Transition to 24/7 monitoring is available, providing continuous security posture management. Implementation timeline varies by scope, but continuity accelerates delivery compared to traditional consultant handoffs.
