Managing endpoint security across hundreds or thousands of devices can quickly become overwhelming. Every organization wants secure configurations, but determining which settings should be enabled, disabled, or monitored often requires extensive security expertise.
This is where Microsoft Intune Security Baselines become invaluable.

Security Baselines provide a pre-configured collection of recommended security settings developed by Microsoft security experts. Instead of manually configuring hundreds of individual settings, administrators can deploy trusted security configurations with just a few clicks.
What Are Security Baselines?
Security Baselines are groups of security settings that represent Microsoft's recommended configuration for securing devices and users.
These settings are based on:
- Microsoft security research
- Industry best practices
- Enterprise security recommendations
- Modern threat intelligence
The primary goal is to help organizations establish a strong security foundation without spending weeks validating individual settings.
Think of Security Baselines as a pre-built security blueprint for your devices.
Why Security Baselines Matter
Many organizations face common challenges:
- Inconsistent device configurations
- Security settings configured differently across teams
- Difficulty identifying secure defaults
- Limited security expertise
- Time-consuming manual policy creation
Security Baselines address these challenges by providing standardized configurations that can be deployed and managed centrally through Microsoft Intune.
Benefits of Security Baselines
Faster deployment of secure settings
Reduced configuration errors
Consistent security posture
Simplified security management
Alignment with Microsoft's recommendations
Lower operational complexity
Types of Security Baselines in Intune
Microsoft Intune offers several baseline categories.
1. Windows Security Baseline
Designed for Windows devices and includes recommendations related to:
- Password policies
- Microsoft Defender settings
- Firewall configuration
- User account controls
- Device security options
This is the most widely used baseline in enterprise environments.
2. Microsoft Defender for Endpoint Baseline
Focuses on advanced endpoint protection features including:
- Antivirus protection
- Attack Surface Reduction (ASR) rules
- Cloud-delivered protection
- Real-time monitoring
- Threat detection settings
Ideal for organizations using Microsoft Defender for Endpoint.
3. Microsoft Edge Baseline
Provides secure browser configurations such as:
- SmartScreen protection
- Privacy settings
- Browser security controls
- Extension management
Protects users during daily web activities.
4. Microsoft Defender for Office 365 Baseline
Helps secure collaboration services by strengthening protection against:
- Phishing attacks
- Malicious attachments
- Unsafe links
- Business email compromise attempts
How Security Baselines Work
Step 1: Create Baseline Profile
Navigate to:
Microsoft Intune Admin Center → Endpoint Security → Security Baselines
Choose the baseline type you wish to deploy.
Step 2: Review Configuration Settings
Each baseline contains hundreds of recommended settings.
Administrators can:
- Accept defaults
- Modify specific settings
- Exclude unnecessary configurations
Step 3: Assign to Groups
Deploy baselines to:
- Device groups
- User groups
- Pilot environments
Starting with a pilot group is always recommended.
Step 4: Monitor Deployment
Track:
- Success rates
- Conflicts
- Configuration failures
- Device compliance
Key Security Settings Included in Baselines
Microsoft Defender Antivirus
Security Baselines often enforce:
- Real-time protection
- Cloud protection
- Automatic signature updates
- Behavior monitoring
These settings help detect and prevent malware attacks.
Firewall Configuration
Baselines typically ensure:
- Firewall enabled
- Inbound traffic restrictions
- Network protection controls
A properly configured firewall reduces exposure to unauthorized access.
Credential Protection
Settings may include:
- Credential Guard
- Secure authentication controls
- Password protection mechanisms
These controls help defend against credential theft.
Attack Surface Reduction
ASR rules help block common attack techniques such as:
- Malicious Office macros
- Script-based attacks
- Suspicious executable files
- Ransomware behavior
This significantly strengthens endpoint resilience.
Security Baseline vs Configuration Profile
This is a common source of confusion.
Security Baseline
Purpose:
- Rapid deployment of recommended security settings
Advantages:
- Microsoft-tested configurations
- Faster implementation
- Simplified management
Configuration Profile
Purpose:
- Customized device settings
Advantages:
- Greater flexibility
- Granular control
- Organization-specific requirements
Best Practice
Use:
Security Baselines for foundational security
AND
Configuration Profiles for business-specific needs
The combination provides both security and flexibility.
Common Deployment Strategy
Phase 1: Pilot Group
Deploy baseline to:
- IT administrators
- Test devices
- Small user population
Validate:
- Application compatibility
- User experience
- Potential conflicts
Phase 2: Department Rollout
Expand deployment to selected business units and gather feedback.
Phase 3: Enterprise Deployment
Roll out organization-wide once testing is complete.
This minimizes disruption and improves success rates.
Monitoring Baseline Health
After deployment, administrators should regularly monitor:
Security Baseline Reports
Review:
- Assigned devices
- Successful deployments
- Failed deployments
Endpoint Security Reports
Track:
- Security posture
- Threat trends
- Policy effectiveness
Compliance Reports
Verify devices continue meeting organizational security requirements.
Regular monitoring ensures long-term effectiveness.
Common Challenges
Policy Conflicts
Sometimes:
- Configuration Profiles
- Group Policy
- Security Baselines
may attempt to configure the same setting.
Result:
Configuration conflicts
Best Practice:
Review overlap before large-scale deployment.
Legacy Application Issues
Older applications may rely on less secure configurations.
Always test baseline settings thoroughly before production rollout.
User Resistance
Enhanced security may introduce:
- Additional prompts
- Restricted actions
- New authentication requirements
Educating users helps improve adoption and reduce support calls.
Security Baselines and Zero Trust
Security Baselines align closely with Zero Trust principles.
Zero Trust assumes:
"Devices should continuously prove they are secure."
Security Baselines help achieve this by ensuring:
- Consistent security settings
- Standardized protections
- Reduced attack surface
- Strong endpoint security posture
When combined with:
- Conditional Access
- Compliance Policies
- Microsoft Defender
- Entra ID
organizations can build a robust Zero Trust architecture.
Best Practices for Success
Start with Microsoft's Defaults
Avoid modifying numerous settings immediately.
Deploy defaults first and introduce changes gradually.
Test Before Production
Always pilot baseline deployments before large-scale implementation.
Monitor Regularly
Security settings should be reviewed as threats evolve.
Document Exceptions
Record all deviations from Microsoft recommendations along with business justifications.
Keep Baselines Updated
Microsoft periodically releases updated baseline versions.
Review and adopt new versions when appropriate.
Final Thoughts
Microsoft Intune Security Baselines provide a powerful way to establish a secure endpoint foundation without the complexity of configuring hundreds of settings manually. They help organizations standardize security, reduce risk, and accelerate their journey toward modern endpoint management.
Rather than guessing which security configurations are important, administrators can leverage Microsoft's expert guidance and focus on maintaining a strong, consistent security posture across the organization.
Endpoint Sphere Takeaway
"Security doesn't have to start from scratch. With Intune Security Baselines, organizations can transform Microsoft's security expertise into a consistent and scalable endpoint protection strategy."
