Maximize iOS Application Security: Stop Wasting Two-Thirds of Your Mobile App Pentesting Efforts

As the famous quote goes about advertising, attributed most often to department store owner John Wanamaker, “Half the money I spend on advertising is wasted, the trouble is, I don't know which half.”
The same issue applies to iOS app pentesting. Security testing often overlooks how the app performs on the most current version of iOS, leaving critical gaps. Why? Approximately 68% of all iPhones are now running iOS18. If your iOS app pentesting strategy is unable to test in Apple’s newest operating system, your application is at risk. Two-thirds of users are running iOS 18, and failing to test on that version leaves major gaps.
Why iOS Application Security Testing is Falling Behind
Traditional mobile app security testing often focuses on functional correctness, not exploitability. But advanced mobile threats increasingly target insecure storage, API vulnerabilities, and root detection flaws—gaps that only surface with dynamic, OS-level pentesting.
Apple's iOS 18 was released in September 2024, followed by iOS 18.1 in October, and we announced Corellium’s support for iOS 18 in our blog. Just last month iOS 18.3.1 was released and we announced that Corellium supports the latest iOS versions, ensuring compatibility with this most recent update. Leveraging Corellium to test your mobile application means your team can analyze the latest iOS devices without compromising functionality or security features.
Corellium not only supports the latest iOS, we also support every prior version -- and since 19% of iPhones are running iOS 17, if you aren’t leveraging Corellium, then more than two thirds of your application security testing efforts aren’t as effective as they could be.
Only Corellium enables mobile application security testing with full access to modern iPhone models, complete with iOS 18.3.1 running on fully jailbroken virtual devices. Whether you're assessing an application’s security or hunting for vulnerabilities, you can now gain root-level access seamlessly, allowing for comprehensive security assessments.
Corellium alleviates the challenge of jailbreaking iOS devices, even for the newest iOS version. Our virtual hardware platform enables built-in jailbreak for iOS 18, removing the constraints of locked-down devices.
Corellium enables continuous, mobile application security testing, on a virtualized hardware platform, for deeper visibility into data security risk during development. Integrates into your mobile application development process and helps identify risk before negative impact to the data security or compliance for mobile applications.
