Modern mobile blind spots

What modern apps miss when security is treated as a checklist.

Today’s mobile apps ship fast, change often, and rely on complex flows. The blind spots aren’t always ‘classic vulnerabilities’—they’re broken assumptions that show up as trust, churn, and deal friction risk.

The thesis

Most problems aren’t caused by exotic exploits. They come from mismatches between how the product is supposed to work and how it behaves under edge cases: state transitions, account switching, deep links, local persistence, and fragile boundaries around sensitive actions.

Questions to ask before a milestone

  • What are the 2–3 flows that would create the most trust damage if abused?

  • What assumptions does the product make about user state and access?

  • Where does sensitive data live (device + backend), and how is it protected in the real build?

  • What happens when a device is compromised (root/jailbreak, backups, shared devices)?

  • How will we verify fixes—not just ‘ship them’?

How we help

A Security Health Check gives you a fast, evidence-backed snapshot of what matters most—and a prioritized plan your engineers can ship and verify.
