TL;DR: 26 and 18 leave mobile security testing without jailbreakable current devices for runtime inspection, Corellium argues in case work. Filesystem, keychain, and network evidence now has to come from paths that still reflect production iOS behavior.
Editorial analysis by NHI Mgmt Group, based on content published by Corellium: “Mobile Security Testing Challenges in 2025: What 2026 Will Demand”.
Key questions
Q: Why does the loss of jailbreak-based testing create compliance risk?
A: Because many assurance frameworks expect demonstrable control testing, not just design claims.
Q: How do teams know whether simulator-based mobile testing is insufficient?
A: Simulator coverage is insufficient when the app’s risk depends on real-device behaviour such as Secure Enclave use, keychain handling, runtime file creation, or SSL pinning.
Q: What breaks when mobile security testing no longer has runtime visibility?
A: Teams lose the ability to prove how an app stores data, handles certificates, and manages secrets on the same operating system versions customers use.
Practitioner guidance
- Audit the current test matrix Inventory the iOS versions you test, compare them with versions in production, and identify where you no longer have runtime evidence for storage, cryptography, or network controls.
- Prioritise high-risk mobile apps first Start with applications that process payment data, identity verification, or sensitive personal information, because those workflows carry the highest audit and abuse impact when runtime visibility is missing.
- Move runtime checks into the delivery pipeline Add mobile security gates that validate filesystem behaviour, certificate handling, and secret storage on current OS versions before release approval.
Bottom line: Mobile security testing on current iOS versions has crossed from difficult to structurally limited, which weakens runtime assurance for real-device behaviour.

Runtime visibility is now a governance control, not a specialist testing enhancement. When current mobile operating systems remove practical jailbreak-based inspection, organisations lose the ability to prove what their apps do on the same platforms customers use. That shifts assurance from evidence-based validation to assumption management, which is a poor fit for regulated mobile environments. Practitioners should treat runtime visibility as part of control design, not a late-stage quality check.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should mobile security teams do when current iOS versions cannot be inspected directly?
A: They should redesign assurance around live-device validation methods that still work on current OS versions, then prioritise the apps with the highest data sensitivity and regulatory exposure. The goal is not more testing volume, but defensible evidence that controls operate in production conditions.
