Who can perform security penetration testing for Android and iOS mobile apps?

Here is my views on Who can help you test your app's security?

1. Security Companies: These are professional companies that specialize in finding security flaws.
2. Independent Security Experts: These are individuals who can test your app for vulnerabilities.
3. Crowdsourced Testing Platforms: These platforms connect you with a community of security testers.

What to look for in a security tester:
-Experience: They should know how to test mobile apps.
-Reputation: They should have a good track record.
-Tools: They should use the latest tools to find vulnerabilities.
-Reporting: They should be able to explain their findings clearly.
