Salesforce Experience Cloud Security Best Practices
Security is one of the most important considerations when building a Salesforce Experience Cloud portal.
Whether you’re creating a customer self-service portal, a partner collaboration platform, or a public knowledge site, your portal often contains sensitive business data, customer information, and operational processes.
Salesforce Experience Cloud security is no longer just a technical concern. Recent security incidents involving misconfigured Experience Cloud sites demonstrated that overly permissive guest user settings can expose sensitive data to unauthorized users. The issue wasn’t a Salesforce platform vulnerability—it was a configuration problem.
Poor security configuration can lead to:
- unauthorized access;
- data exposure;
- compliance issues;
- reputational damage;
- increased operational risk.
In this guide, we’ll explore Salesforce Experience Cloud security best practices and explain how to secure customer and partner portals while maintaining a great user experience.
Why Salesforce Experience Cloud Security Matters
Experience Cloud sites are different from internal Salesforce applications because they serve external audiences:
- customers;
- partners;
- suppliers;
- anonymous visitors;
- community members.
This creates additional security requirements.
Organizations must protect:
- personally identifiable information (PII);
- customer records;
- files and documents;
- business processes;
- API endpoints.
Strong security practices also support compliance initiatives such as GDPR, SOC 2, HIPAA, and industry-specific regulations.
Understanding the Four Layers of Experience Cloud Security
Experience Cloud security works in layers.
1. Authentication
Determines who can access the portal.
Examples:
- Username and Password
- Single Sign-On (SSO)
- Multi-Factor Authentication (MFA)
2. Object Permissions
Determines which objects users can access.
Examples:
- Cases
- Accounts
- Opportunities
- Custom Objects
3. Record Access
Determines which records users can see.
Examples:
- Organization-Wide Defaults
- Sharing Rules
- Sharing Sets
- Account Relationships
4. Field-Level Security
Determines which fields are visible to users.
Even if a user can see a record, sensitive fields should remain hidden when necessary.
A secure Experience Cloud implementation requires all four layers to work together.
Best Practice #1: Apply the Principle of Least Privilege
The most important security principle is simple:
Give users only the access they actually need.
Avoid:
- broad permissions;
- unnecessary object access;
- excessive CRUD permissions;
- large permission sets.
A good model looks like this:
Authentication
↓
Site Membership
↓
Profile
↓
Permission Sets
↓
Sharing Rules
↓
Field-Level Security
Whenever possible:
- keep Profiles minimal;
- use Permission Sets to extend access;
- review permissions regularly.
This approach is easier to audit and significantly reduces security risks.
Best Practice #2: Design a Secure Sharing Model
Many Experience Cloud security problems are caused by overly permissive sharing settings.
Follow these recommendations:
- use Private Organization-Wide Defaults whenever possible;
- grant access only where necessary;
- avoid exposing records broadly;
- regularly review sharing rules.
Pay special attention to:
- Sharing Sets;
- Guest User Sharing Rules;
- Account Relationships.
A common mistake is enabling Public Read/Write access simply to make a portal feature work.
That approach almost always creates future security problems.
Best Practice #3: Secure Guest User Access
This is arguably the most important Experience Cloud security topic today.
Salesforce has repeatedly warned customers about the risks of misconfigured Guest Users and recommends a zero-trust approach.
Keep Guest Access to an Absolute Minimum
Guest users should only access:
- login pages;
- public knowledge articles;
- public forms;
- carefully selected records.
Never Grant View All or Modify All Permissions
Guest users should never have:
- View All Records;
- Modify All Records;
- broad object access.
Review API Enabled Permission
Salesforce strongly recommends disabling API access for Guest Users unless it is absolutely required.
Audit Guest User Sharing Rules
Guest User Sharing Rules grant access to unauthenticated users.
Use them carefully.
Salesforce explicitly warns that improperly configured sharing rules can expose records to anyone on the internet.
Never Allow Guest Users to Own Records
Records created by Guest Users should be automatically reassigned to an authenticated default owner.
Disable Self-Registration If It Isn’t Needed
Following recent attacks against public Experience Cloud sites, Salesforce recommended disabling self-registration when it isn’t required and reviewing all public pages and Guest User permissions.
Best Practice #4: Use Profiles and Permission Sets Carefully
A common security problem is permission sprawl.
Recommendations:
Keep Profiles simple.
Use Permission Sets for additional access.
Use Permission Set Groups where appropriate.
Review assignments quarterly.
This approach makes Experience Cloud environments easier to manage and audit.
Best Practice #5: Enable Multi-Factor Authentication (MFA)
MFA significantly reduces the risk of account compromise.
Experience Cloud supports:
- Salesforce Authenticator;
- TOTP applications;
- third-party identity providers.
For portals containing sensitive customer or partner data, MFA should be considered mandatory.
Best Practice #6: Secure Authentication and Login Policies
Review:
- password policies;
- session timeout;
- login hours;
- IP restrictions;
- Single Sign-On settings.
Strong authentication controls reduce the likelihood of unauthorized access.
Best Practice #7: Protect Files and Documents
Files are often overlooked during security reviews.
Review:
- Salesforce Files visibility;
- Content Delivery links;
- external sharing;
- file permissions.
A secure object model can still expose sensitive information through improperly shared files.
Best Practice #8: Monitor and Audit Portal Activity
Security is not a one-time configuration exercise.
Use Salesforce monitoring tools:
- Login History;
- Event Monitoring;
- Setup Audit Trail;
- Security Health Check.
Monitor for:
- unusual login patterns;
- unexpected API activity;
- spikes in Guest User traffic;
- permission changes.
Recent Experience Cloud incidents demonstrated the importance of continuously monitoring public sites and investigating suspicious activity quickly.
Best Practice #9: Secure Integrations and Connected Apps
Every integration increases your attack surface.
Review:
- OAuth policies;
- Connected Apps;
- API access;
- token expiration policies.
How to Prepare for a Salesforce Connected App Audit
Best Practice #10: Review Security Regularly
A security review should be performed at least quarterly.
Checklist:
✓ Review permissions.
✓ Audit sharing rules.
✓ Review Guest User access.
✓ Verify MFA.
✓ Review integrations.
✓ Remove inactive users.
✓ Test record visibility.
✓ Audit public pages.
Common Salesforce Experience Cloud Security Mistakes
Excessive Guest User Permissions
Overly Permissive Sharing Rules
Missing MFA
Exposed Files
Unused Connected Apps
Excessive API Access
No Regular Security Reviews
These issues appear frequently during Experience Cloud security assessments and can often be resolved through proper governance and regular audits.

Conclusion
Salesforce Experience Cloud security should be planned from the beginning of every implementation—not added later.
Most Experience Cloud security incidents are caused by misconfigured guest user access and overly permissive sharing settings, not platform vulnerabilities.
By applying the principle of least privilege, securing guest access, enabling MFA, auditing integrations, and continuously monitoring portal activity, organizations can build customer and partner experiences that remain secure as they scale.
A secure Experience Cloud portal doesn’t just reduce risk—it builds trust, improves compliance, and protects your most valuable data.
