Penetration Testing
Web & mobile
The product your customers use — onboarding, checkout, account settings, and the admin paths behind them.
Security testing for Nigerian fintech applications
Most fintech apps have at least one critical vulnerability in auth, payments, or API access. We identify and work closely with your team to fix high-impact security issues — before you or your users lose another naira to hackers.
payments auth admin tools api boundaries
Tested by engineers, not auditors.
Findings you can fix, not shelf.
Remediations that actually work for you.
Scoped to your real attack surface.
What we test
Testing that follows how your product actually works.
Vulnerability Assessment
Signal over noise
Ranked findings with proof of exploitability. Not a scanner dump of theoretical risks.
Authentication & API Security
Sessions, tokens, authz
Token lifecycle, session handling, permission checks, and the handoffs between services where assumptions break.
Secure Architecture Review
Trust boundaries
How secrets travel, where integrations over-trust, and what internal dashboards expose.
Why Simpa Labs
Built for teams shipping fast on other people's money.
Startup pace, not enterprise timelines
No six-week scoping periods. Reviews fit how fast you actually ship.
Findings your engineers will use
Severity, proof, impact, fix. Per finding. Nothing that needs translation.
Full product, one engagement
Frontend, backend, mobile, APIs, and admin tools — reviewed as a connected system, not isolated slices.
Tooling built for fintech edge cases
Proprietary tools that catch what automated scanners miss in payment and identity flows.
Proof
What a review turns up
Anonymized. Details available on request.
Account takeover via recovery chain
/recovery -> /session-upgrade -> /email-change
Password recovery chained into session upgrade into email change. Three normal product features. Combined: full account takeover.
Fix priority: immediate
Privilege escalation through stale tokens
/login -> /refresh-token -> /admin-actions
Refresh tokens outlived logout. Admin actions checked permissions at login, not at execution. Expired sessions still carried full authority.
Fix priority: this sprint
PII leakage across internal surfaces
/exports -> /logs -> /support-views
Customer data appeared in export endpoints, application logs, and a support view accessible to every staff account.
Fix priority: before scale
How it works
Three steps. No bloat.
- 01
Intake
Short call to map your product surface, release cadence, and where you feel least covered.
- 02
Assessment
Testing targets high-risk flows: authentication, payments, onboarding, admin operations, and integration seams.
- 03
Report
Every finding includes severity, proof, business impact, and a fix you can merge this sprint.
