What you get
Clear output before, during, and after the review.
You should not need to guess what the work looks like. The scope, report format, retest letter, and paperwork are all visible before you book.
Named consultant
The first page shows who is responsible for the work, what is in scope, review dates, boundaries, and client contacts.
Retest
When fixes go live, you get the opportunity for a retest and you learn what passes, what did not, and what still needs another look.
Plain English for non-engineers
Founders, finance people, partners, auditors. Most of them will not read a 40-page technical report, and honestly, fair.
What we test
The review follows the money, the users, and the weird edge cases.
Penetration Testing
Web, mobile, admin
I walk the flows people actually use: signup, wallet, checkout, account settings, support tools, and the awkward admin bits nobody demos.
Vulnerability Assessment
Short list, no noise
Not a giant export. You get the issues that matter, why they matter, and where your developer should start on Monday morning.
Authentication Security
Login, OTP, sessions
Password reset, OTP, device change, refresh tokens, role checks. Boring stuff, until one loose check lets the wrong person in.
API Security
Boundaries and leakage
Tenant separation, object access, rate limits, webhooks, partner callbacks, and those tiny ID leaks that turn into serious problems.
Secure Architecture Review
The expensive stuff
Secrets, logs, cloud permissions, data movement, third-party tools, production access. The pieces that get painful to clean up later.
Why Simpa Labs
Small, direct, and allergic to secrity theatre.
Scope in writing
You know who is doing the review, what is included, what is off-limits, and what documents you are getting at each point.
Findings engineers can actually fix
Each issue comes with the affected flow, exact evidence, business risk, and fix. No clever-sounding waffle.
The whole product, considered as one system not a series of endpoints
Fintech bugs like to hide in business logic. We review the interactions between infrastructure, mobile and web apps, APIs, admin panels, support and third party integrations.
Paperwork sorted early
NDA, service terms, SOW, and testing authorization are ready before you hand over access. Less back-and-forth. Better.
The paperwork
Read the templates.
Some teams ask for documents late and then everything drags. No need. These are the blank forms used before access is shared; names, dates, fees, and exact scope only go in after both sides agree.

Report Sample A complete example: summary, severity counts, findings, proof notes, fix plan, owners, and retest criteria. DOCX Mutual NDA Covers confidential product, technical, business, and security information shared during scoping and delivery. DOCX Service Agreement The basic business terms. Useful before anyone starts sharing access. DOCX Statement of Work What is being reviewed, when, for how much, and what counts as done. DOCX Testing Authorization Permission in writing, with boundaries, hours, contacts, and the no-drama rules. DOCX Data Handling Note How files, evidence, notes, credentials, and screenshots are handled. DOCX Retest Letter A simple confirmation after your team fixes the reported issues. DOCX Invoice / Receipt Billing details and receipt confirmation, kept plain. DOCX
Example findings
Real findings. Sanitized.
Client reports stay private. These examples show the kind of issues that appear in fintech products like yours.
Password recovery leads account takeover
forgot password -> fresh session -> email change
Each feature looked normal on its own. Put together, the reset flow let an unauthorized user step into an account that was not theirs.
Fix this before launch
Broken Token invalidation Logic
login -> refresh token -> privileged action
Logout happened, but the token still worked in places it should not. The permission check was absent in places it should not.
Fix in the current sprint
Customer data Leak in sensitive locations
export file -> logs -> support view
The app was not screaming. That was the problem. Sensitive customer details were sitting in exports, logs, and a support screen any support staff could open.
Clean up before you put customers at risk
