Picture this: You've spent six months building your Salesforce app. Your development team has poured countless hours into features your customers will love. You submit it for the Salesforce security review, confident you'll be listed on AppExchange within weeks.

Then the rejection email arrives.

"Your application does not meet our security requirements."

Back to the drawing board. Another month of development. More delays for your go-to-market strategy. Frustrated stakeholders. And worst of all? This scenario happens to over 60% of first-time AppExchange submissions.

Here's the truth: The Salesforce security review isn't just a formality. It's a rigorous examination that protects millions of Salesforce users from vulnerabilities, data breaches, and compliance nightmares.

But here's the good news: With the right preparation and a comprehensive Salesforce security review checklist, you can pass on your first attempt.

I've helped dozens of ISV partners navigate this process successfully. Today, I'm sharing the exact framework that's helped teams avoid costly delays and launch their apps faster.

The Salesforce security review is a mandatory assessment for any app seeking public listing on the AppExchange marketplace. Think of it as a security audit that validates your application meets Salesforce's strict standards for data protection, authentication, and code quality.

Salesforce takes this seriously because your app will potentially access sensitive customer data across thousands of organizations.

The review examines several critical areas:

• Code security practices and vulnerability testing

• Data handling and encryption protocols

• Authentication mechanisms and session management

• API security and rate limiting

• Third-party integrations and dependencies

Passing this review isn't optional if you want AppExchange visibility. But the benefits extend beyond marketplace access—it validates your commitment to security and builds customer trust.

After analyzing hundreds of security review submissions, I've identified the top reasons apps get rejected:

Many developers assume Salesforce's built-in protections are enough. They're not.

Your app must validate and sanitize all user inputs to prevent injection attacks. This includes SOQL injection, XSS (cross-site scripting), and command injection vulnerabilities.

Common mistake: Accepting user input directly into SOQL queries without proper escaping or binding variables.

Session tokens must be handled securely throughout the user journey. Weak session management opens the door to session hijacking and unauthorized access.

Your application needs proper HTTP security headers to protect against common web vulnerabilities. Missing Content Security Policy (CSP) or X-Frame-Options headers are red flags for reviewers.

Error messages that expose sensitive system information, stack traces, or database structures create security risks. Your error handling should be informative for developers but generic for end users.

Believe it or not, incomplete security documentation causes many rejections. Reviewers need clear explanations of your security architecture, data flows, and threat mitigation strategies.

Let me walk you through the exact checklist that's helped my clients achieve first-time approval.

Before you even think about submitting, complete these foundational steps:

• Create a comprehensive security architecture document

• Map all data flows between systems

• Document authentication and authorization mechanisms

• List all third-party services and APIs used

• Prepare vulnerability assessment reports

• Implement parameterized queries for all SOQL/SOSL operations

• Apply proper encoding for all user-generated content

• Use platform-provided security libraries (like String.escapeSingleQuotes())

• Enable and configure CRUD/FLS (Field-Level Security) checks

• Remove all hardcoded credentials and sensitive data

Pro tip: Create a dedicated security review environment that mirrors production but allows reviewers safe access.

This is where most teams need to roll up their sleeves.

Your Salesforce security review checklist must include rigorous input validation:

• Validate all input types (text, numbers, dates, files)

• Implement whitelist validation where possible

• Sanitize HTML content using Salesforce's sanitization methods

• Escape special characters in dynamic SOQL

• Limit file upload sizes and validate file types

• Implement rate limiting for API endpoints

Real-world example: A financial services app we reviewed was accepting currency amounts as raw strings. By implementing strict numeric validation with decimal precision checks, we prevented potential calculation errors that could have cost customers thousands.

Security reviewers scrutinize how you verify user identity and control access:

• Implement OAuth 2.0 for authentication (required for connected apps)

• Use Salesforce's session management (never create custom sessions)

• Enforce proper permission checks before data operations

• Implement role-based access controls (RBAC)

• Validate sharing rules are respected

• Check object and field-level permissions before CRUD operations

Protecting customer data is non-negotiable:

• Encrypt data in transit using TLS 1.2 or higher

• Implement encryption for sensitive data at rest

• Use Salesforce Shield Platform Encryption for highly sensitive fields

• Implement proper key management practices

• Ensure PII (Personally Identifiable Information) is handled securely

• Document data retention and deletion policies

Salesforce expects you to actively hunt for vulnerabilities before submission.

• Run Salesforce CLI Scanner on your codebase

• Use PMD or similar tools for code quality checks

• Review and fix all critical and high-severity findings

• Document any accepted risks with justification

• Ensure code comments don't contain sensitive information

• Perform penetration testing on your application

• Test for OWASP Top 10 vulnerabilities

• Conduct injection attack testing (SOQL, XSS, etc.)

• Test session management and timeout behaviors

• Verify proper error handling under attack scenarios

Important: Keep detailed records of all testing performed. Reviewers often request this documentation.

If your app connects to external services, pay special attention here.

• Implement API authentication (API keys, OAuth tokens)

• Validate all API responses before processing

• Implement timeout handling for external calls

• Use HTTPS for all external communications

• Implement circuit breakers for failing services

• Log all external API interactions

• Audit all third-party libraries and packages

• Ensure all dependencies are current and patched

• Document the security posture of each dependency

• Remove unused libraries and code

• Verify open-source licenses are compatible

Cautionary tale: One app was rejected because it used a JavaScript library with a known CVE (Common Vulnerabilities and Exposures). The library wasn't even actively used—it was just included in the codebase. Always audit your dependencies.

This is often the most underestimated aspect of the Salesforce security review process.

• Security architecture diagram showing data flows

• Threat model identifying potential risks

• Security controls matrix mapping threats to mitigations

• Vulnerability assessment report with remediation status

• Data classification and handling procedures

• Incident response plan

• Change management procedures

Write your security documentation as if you're explaining to a skeptical CISO (Chief Information Security Officer). Be thorough but clear.

Include:

• Assumptions about the security environment

• Boundaries of what your app protects

• Limitations and known constraints

• Compensating controls for accepted risks

Data privacy regulations are tightening globally. Salesforce reviewers check compliance carefully.

• Implement privacy policy accessible from the app

• Provide clear data collection notices

• Enable user consent mechanisms where required

• Implement data portability features (GDPR requirement)

• Create data deletion workflows

• Document data processing agreements

Consider these common requirements:

• GDPR compliance for EU data subjects

• CCPA compliance for California residents

• HIPAA considerations for healthcare apps

• SOC 2 controls for enterprise customers

• PCI DSS for payment processing

You're almost ready to submit. Don't skip these final verification steps.

• Test app installation in a fresh Salesforce org

• Verify all security configurations deploy correctly

• Test with different user profiles and permission sets

• Confirm no hard-coded org-specific IDs or URLs

• Validate all remote site settings are documented

• Complete security questionnaire accurately

• Upload all required documentation

• Provide clear deployment instructions

• Include test user credentials (with proper permissions)

• Document any special configuration steps

Pro tip: Have someone unfamiliar with your app attempt the installation using only your documentation. If they struggle, reviewers will too.

Let me share some real scenarios I've encountered:

Problem: Your app works perfectly in your development org but fails during security review because you've made assumptions about permissions or configurations.

Solution: Test installation in a completely fresh org with minimal customizations. Use standard profiles first, then custom profiles.

Problem: Your app relies on an external service that goes down during the review period, causing functionality failures.

Solution: Implement graceful degradation. Your app should handle external service failures without crashing. Include mock services for testing scenarios.

Problem: Your technical documentation is excellent, but your security documentation is an afterthought.

Solution: Treat security documentation as a first-class deliverable. Allocate proper time and resources. Consider hiring a security professional to review.

Understanding the timeline helps you plan accordingly:

1. Submission: You submit your app and documentation

2. Initial Review (1-2 weeks): Automated scans and preliminary checks

3. Deep Dive (2-4 weeks): Manual security testing and code review

4. Clarifications (variable): Back-and-forth on findings

5. Final Review (1-2 weeks): Verification of remediation

6. Approval: You're cleared for AppExchange listing

Total time: Expect 6-10 weeks for a clean, well-prepared submission. Factor in additional time for any remediation required.

Here are insider insights that can make the difference:

If reviewers ask questions, respond quickly with detailed answers. Delays in communication extend the review timeline significantly.

When explaining security controls, provide the "why" behind your decisions. Reviewers appreciate understanding your threat model and risk assessment process.

Security review feedback makes your app better. Even if comments seem harsh, they're protecting your customers and your reputation.

Don't treat security review as a final gate. Integrate security practices throughout development:

• Security requirements in user stories

• Security-focused code reviews

• Regular vulnerability scanning

• Security testing in your CI/CD pipeline

Leverage these tools to strengthen your Salesforce security review checklist:

• Salesforce CLI Scanner: Static analysis for security issues

• Security Health Check: Baseline security settings

• Field Audit Trail: Track sensitive data changes

• Event Monitoring: Monitor suspicious activities

• Checkmarx: Application security testing

• Veracode: Static and dynamic analysis

• OWASP ZAP: Open-source security testing

• Burp Suite: Web application security testing

• Salesforce provides security review documentation templates in the Partner Community

• Use these as starting points and customize for your application

The typical security review process takes 6-10 weeks from submission to approval. However, this timeline assumes your application is well-prepared with complete documentation and minimal security findings. Apps requiring significant remediation can take 12-16 weeks or longer. Submitting during Salesforce's busy periods (end of quarter) may also extend timelines.

Yes, you can resubmit your application after addressing all identified security issues. Salesforce provides detailed feedback on why your app was rejected. Most teams need to remediate findings and resubmit within 30-60 days. There's no penalty for resubmission, but delays impact your go-to-market timeline and revenue projections.

The initial security review is included with your AppExchange Partner Program membership. However, significant updates to your app may require a re-review, which could incur fees. Budget for internal costs including security testing tools, potential security consultants, and developer time for remediation work—typically $10,000-$50,000 depending on app complexity.

While not strictly required, having a security professional review your application before submission significantly increases first-time approval rates. Consider hiring a consultant if your team lacks deep security expertise or if you're building apps handling sensitive data like financial, healthcare, or personal information.

If a security vulnerability is discovered in your app post-approval, Salesforce may require an emergency patch or temporarily delist your app from AppExchange until the issue is resolved. Maintain ongoing security practices including regular penetration testing, monitoring security bulletins for dependency vulnerabilities, and having an incident response plan ready.

The Salesforce security review checklist I've shared isn't just about passing an assessment—it's about building trust with your customers and protecting their data.

Yes, the process is rigorous. Yes, it requires significant effort. But apps that prioritize security from day one move faster through the review and build stronger customer relationships.

Remember these key takeaways:

Start security early in your development process, not as an afterthought before submission.

Document thoroughly—reviewers can't approve what they don't understand about your security architecture.

Test extensively using both automated tools and manual security assessments before submission.

Communicate clearly with reviewers and respond promptly to any questions or findings.

The teams that succeed treat security review as a continuous practice, not a one-time gate. They build security into their culture, processes, and code from the very first sprint.
