Security that keeps up with how fintech ships.
Neobanks and wallets release fast and carry money, identity and API keys in a binary on a hostile device. Mobexa tests the exact build on every release, proves where tokens, APIs and tamper defenses hold, and turns it into PSD2 and PCI-DSS-ready evidence - without slowing the train down.
Where fintech apps actually get hit
The expensive incidents come from the device and the API edge - not the parts a web scanner can see.
Tokens & secrets
Access tokens in weak storage and API keys reachable in the binary - the shortest path to account takeover.
Mobile API edge
How the app talks to your backend, what it trusts, and whether pinning and request integrity actually hold at runtime.
SDK supply chain
Payment, KYC and analytics SDKs inventoried and matched to known CVEs - the third-party risk inside your app.
Continuous, evidenced, on your release train
Fintech cannot trade velocity for security, and cannot hand build artifacts to a black box during partner-bank onboarding. Mobexa runs on every build, can stay fully inside your perimeter, and produces evidence that ties each finding to the control behind it.
- Every release tested, gated only on new criticals.
- PSD2, PCI-DSS, GDPR, KVKK mappings auditors and partner banks accept.
- Self-hosted option so artifacts never leave your network.
- SARIF + ticketing so fixes land in the tools engineers already use.
Every app, one risk number
Core app, wallet, onboarding, partner white-labels - findings land in one deduplicated backlog with severity, ownership and SLA timers, and a trend leadership can report. Android and iOS read as a single estate.
Where fast-moving fintech releases usually leak risk
Fintech teams ship weekly and lean on SDKs to move fast. The exposures follow the same pattern: velocity outruns the review of what actually ends up in the binary.
SDK sprawl with stale versions
KYC, card-scanning and analytics SDKs pinned to old releases with published CVEs, invisible without an SBOM of every build.
Test endpoints in production builds
Staging URLs, debug flags and feature switches left compiled into the release the app store serves.
Onboarding data over-collected
Identity documents and selfies cached on device longer than the flow requires, a direct GDPR and KVKK exposure.
Deep links without validation
Payment and referral deep links accepting unvalidated parameters, usable for account-state manipulation.
Fintech mobile security, answered plainly
Fintech ships every week. Does security have to slow that down?
No. Mobexa runs on the build your CI already produces and returns findings as SARIF, so testing rides your existing release train instead of blocking it. You can gate only on new criticals, keeping fast iteration while still catching the exposure that matters before it reaches users.
What is different about a fintech threat model?
Fintech apps concentrate money, identity and API keys in a binary that runs on a hostile device. The exposure that hurts is account takeover through leaked secrets, abused mobile APIs, weak token storage and missing tamper resistance - exactly the binary-level material Mobexa is built to read.
Can the evidence support PSD2, open banking and PCI-DSS reviews?
Findings map to OWASP MASVS and roll up to PCI-DSS, PSD2 strong-customer-authentication expectations, GDPR and KVKK. You get traceable technical proof tied to each control, which is what regulators and partner banks ask for during onboarding.
We embed third-party finance SDKs. Are those covered?
Yes. Mobexa inventories every bundled SDK and library, matches them to known CVEs, and flags the supply-chain risk you ship inside your own app - the dependencies you did not write but are still accountable for.
Test every release in your own pipeline.
We will wire Mobexa into a build of your choosing and show findings, evidence and the gate in your own pipeline.
