Cloud Security Hardening — Azure & Microsoft 365
Secure Your Identities, Access and Cloud Data Before Attackers Do
Cyber Sentinel Solutions Ltd — London & Bristol, UK
We help UK organisations harden their Azure and Microsoft 365 environments by closing common security gaps in identity, access control, configuration, logging and monitoring.
Why Cloud Security Hardening Is Critical
Many modern attacks never touch your on-premises network. Instead, they target cloud identities, weak authentication policies and misconfigured Azure / Microsoft 365 tenants.
Typical weaknesses we see include:
- incomplete or inconsistent MFA rollout
- over-privileged global admin accounts
- legacy authentication still enabled
- overly permissive sharing in SharePoint and OneDrive
- risk-based or conditional access not in use
- Defender alerts not reviewed or tuned
- poor logging coverage for sign-ins and cloud activity
Attackers use these gaps to perform account takeover, data theft and ransomware operations — often without touching a VPN or internal network.
What Is Cloud Security Hardening?
Cloud Security Hardening is a focused effort to tighten your Azure and Microsoft 365 configuration so that attackers have fewer opportunities to exploit misconfigurations or over-privileged accounts.
We focus on:
- identities and access control (Entra ID / Azure AD)
- authentication (MFA, Conditional Access, risk-based controls)
- privileged accounts and roles
- data access and sharing
- Defender security controls
- logging and monitoring
The result is a cloud environment that is significantly harder to abuse, even when credentials are stolen or phishing succeeds.
Scope of Cloud Security Hardening
1. Identity & Access (Entra ID / Azure AD)
- review of admin accounts and privileged roles
- implementation or tuning of Privileged Identity Management (PIM)
- analysis of group memberships and role assignments
- hygiene of break-glass and emergency accounts
2. Authentication & Conditional Access
- MFA rollout and enforcement review
- Conditional Access policy design or optimisation
- blocking of legacy authentication
- session controls and sign-in risk policies
3. Data Access & Sharing
- external sharing configuration for SharePoint and OneDrive
- Teams data access and guest access settings
- permissions for high-sensitivity locations
- data leakage paths through cloud apps and connectors
4. Defender & Security Controls
- Microsoft Defender for Office 365 policies
- Defender for Cloud & endpoint integration review
- secure baseline for email filtering and safe links/attachments
- security recommendations from Defender for Cloud / Secure Score
5. Logging, Monitoring & Alerting
- sign-in log retention and use
- Audit logs for M365 and Azure resources
- Log Analytics and SIEM integration
- critical alert definitions and escalation paths
Our Hardening Methodology
We combine Microsoft best practices, CIS Benchmarks and real-world attacker techniques seen in ransomware and account takeover incidents.
Typical hardening engagement:
- Discovery and baseline review of current tenant configuration
- Identification of high-risk misconfigurations and privileges
- Design of improved policies and control sets
- Implementation or guided implementation of changes
- Validation and monitoring of new settings
- Final documentation and knowledge transfer
Work can be done fully by us, or collaboratively with your internal IT / MSP team.
What You Receive
- baseline risk assessment of your current Azure/M365 configuration
- list of misconfigurations and high-risk settings
- new or improved Conditional Access and MFA policies
- cleaned-up privileged roles and admin accounts
- hardened external sharing and guest access settings
- Defender and logging configuration improvements
- documentation of the new security baseline
Who Is This For?
Cloud Security Hardening is ideal for organisations that:
- use Azure and Microsoft 365 as core platforms
