What are the benefits of outsourcing penetration testing for cloud apps?

Outsourcing gives you access to specialized testers who bring an attacker's perspective without the cost of building that expertise in-house. An experienced third party can simulate real-world threats more objectively than internal teams, since they aren't testing their own work. For cloud-hosted applications specifically, an outside team familiar with mobile and API testing can uncover vulnerabilities in network communications, backend integrations, and authentication that internal reviews often miss.
