Mobile App Security Audit

WHOAMI’s Mobile App Security Audit service provides a business‑aware iOS/Android application security assessment across the full ecosystem (APIs, authentication, sessions, storage, integrations). We identify relevant weaknesses and prioritize fixes by risk and operational impact, helping reduce data exposure, feature abuse, and trust erosion.

Mobile App Security Audit Service in Spain

WHOAMI provides mobile security audits in Spain for organizations building apps for customers, employees, or partners. We define a controlled scope and deliver an actionable plan for product and engineering, with evidence and clear priorities.

For companies and product teams

Mobile apps often concentrate personal data, persistent sessions, and integrations (payments, SSO, analytics, push). A weakness here rarely stays “mobile‑only”: it can translate into privacy exposure, fraud, reputational damage, and operational disruption. That’s why we focus on consequences and practical remediation decisions—not generic lists.

Objective and scope (what’s in, what’s out)

The objective is to identify weaknesses that affect confidentiality, integrity, availability (resilience to abuse), and traceability. Typical scope includes:

• Mobile application: permissions, configuration, local storage, secret handling, error handling
• Authentication and session: login, MFA if applicable, renewal, expiry, cookies/tokens
• Backend communication: API usage, validations, authorization/state consistency
• Integrations: SDKs, analytics, push notifications, deep links, SSO, third parties
• Privacy: minimization, accidental exposure, consistency with declared behavior

What we validate (and why it matters)

In a mature mobile assessment, controls map to business impact. Examples:

• Session handling: reduces unwanted persistence and improper access caused by weak session controls
• App‑API authorization consistency: prevents out‑of‑role actions and feature abuse
• On‑device data protection: lowers exposure of sensitive data in realistic scenarios (lost devices, backups, etc.)
• Third‑party integrations: reduces data leakage and misconfigured dependency risk
• Deep links and flows: prevents unintended access to sensitive screens/actions
• Abuse resilience: improves resistance to automation, enumeration, and abnormal usage

Mobile audit vs web audit

A mobile audit covers the app plus the ecosystem. In many products, real risk sits in role and state consistency between the app and the backend. If you need deeper backend coverage, a complementary Web Security Audit is the right fit—without mixing objectives.

Typical engagement modes (black box / grey box / white box)

• Black box: minimal starting information; useful to measure initial exposure
• Grey box: test roles + minimal documentation; typically best value
• White box: team support and architecture detail; ideal for critical apps

Deliverables (what you receive)

• Executive report (risk, impact, priorities, decisions)
• Technical report with evidence, context, and actionable remediation guidance
• Improvement roadmap (quick wins vs design/architecture work)
• Suggested backlog for engineering (grouped actions/tickets)
• Results review session with product/engineering
• Follow‑up review (optional) to confirm critical fixes

What we need to start

To keep the engagement efficient and low‑friction:

• Builds or internal distribution (TestFlight / Play Internal, etc.)
• Test credentials with representative roles
• Endpoints and minimal documentation for critical flows
• Preferred environment: staging when possible

How we prioritize (defensible criteria)

We prioritize by impact (data, fraud, reputation), exposure (roles/surface), likelihood (friction/controls), and cost/benefit. This enables:

• Quick wins with immediate risk reduction
• Structural improvements (roles, flows, integrations) planned with clarity
• Avoiding “patches” that merely shift risk to another layer

Common risk patterns we typically see (no how‑to)

Without turning this into a technical manual, real environments often show patterns such as:

• Over‑persistent sessions or inconsistencies between app and backend
• Role/permission gaps across screens and flows
• Accidental data exposure through on‑device storage or integrations
• Third‑party integrations configured beyond what the product needs
• Limited abuse resilience on high‑impact flows (recovery, profile changes, onboarding)

Timelines and planning

It depends on platform count (iOS/Android), flow complexity, and depth. As a guideline:

• Simple app: typically 1–2 weeks
• Mid‑size app with roles/integrations: typically 2–4 weeks
• Critical app (payments/SSO/multi‑tenant): phased by objectives

How the results fit into releases

We tailor the output to your delivery cycle so it becomes execution:

• Hotfix candidates for immediate exposure reduction
• Sprint‑friendly work for session/roles/integration improvements
• Governance recommendations (SDKs, permissions, data minimization) to prevent regressions

What this audit is NOT (service boundaries)

• Not a certification nor a guarantee of total security
• Not a how‑to manual: we describe risk and impact, not offensive recipes
• Not a development service: we deliver a plan and support review/alignment
