To prepare for a security review, here are the proactive steps you should take:
1. **Secure Your Solution**: Follow industry-standard security practices and address common vulnerabilities like injection attacks, cross-site scripting (XSS), cross-site request forgery (CSRF), and insecure cryptography.
2. **Enroll in the AppExchange Partner Program**: Ensure your solution is Lightning Ready.
3. **Connect to the AppExchange Partner Console**: Link your packaging org and create a provider profile.
4. **Thorough Testing**: Perform manual testing and automated scans using tools like Salesforce Code Analyzer and Source Code Scanner (Checkmarx).
5. **Address Security Issues**: Fix any identified issues or document false positives.
6. **Prepare Submission Materials**: Gather a Developer Edition org with the solution installed, solution documentation, and any required credentials or test environments.
7. **Schedule Office Hours**: Consult with the Security Review Operations or Product Security team for guidance or questions.
8. **Final Preparations**: Complete all necessary testing and ensure your solution is ready for submission.
These steps will help ensure a smooth security review process.
