The barrier to entry for a pentest company is a laptop and an internet connection. This creates a massive quality variance in the market. You can pay millions of Naira for a 200-page PDF generated by a tool, or you can pay the same amount for a team of adversarial engineers who map your payment flow and find the exact API call that drains your treasury.
Finding the right pentest company requires technical vetting. You must interview the vendor exactly like you interview a senior software engineer. Do not accept sales rhetoric. Demand evidence.
Why this decision matters more than you think
A penetration test is not a commodity. The difference between a competent assessment and a checkbox exercise can be the difference between catching a critical BOLA flaw in your payment API and missing it entirely, then reading about it in a breach disclosure six months later.
The Nigerian fintech ecosystem is growing fast, and with it comes a surge of firms offering "penetration testing services." Some are excellent. Many are not. I have reviewed pentest reports from other vendors that were clearly auto-generated vulnerability scan outputs with a logo slapped on top. That is not a pentest. It is a PDF you paid too much for.
Whether you are preparing for CBN compliance, investor due diligence, or an enterprise partnership, the quality of your pentest vendor directly impacts your security posture and business outcomes.
Judge the work
Ask for a redacted report from the team that will test your product. Check whether each finding shows the request, changed input, affected role, server response, business impact, fix, and retest result.
Meet the assigned tester before signing. A sales representative cannot test your application. The individual engineer assigned to your project determines the quality of the engagement. Give them one product flow and ask how they would test its roles, states, amounts, retries, callbacks, and failure paths. A clear answer shows how they think. If they immediately list automated tools, they lack manual testing depth.
Assess their adversarial mindset. A good tester does not look at a form and ask, "Does it validate input?" A good tester asks, "Can I change the currency parameter to bypass the exchange rate logic?"
Demand clear evidence
Confirm the assigned tester's name, relevant product work, sample report, test plan, report format, and retest terms before scoping ends. Accept no substitutions after signing.
Methodology: OWASP, PTES, or proprietary?
Any credible pentest firm should follow a recognised framework. The two most common are:
OWASP Testing Guide: The standard for web and API security testing. If a firm tests fintech applications without referencing OWASP's fintech-relevant categories, that is a problem. OWASP covers authentication flaws, injection, BOLA, SSRF, and the business logic issues that matter most in payment systems.
PTES (Penetration Testing Execution Standard): A broader framework covering pre-engagement, intelligence gathering, threat modelling, exploitation, post-exploitation, and reporting. PTES gives structure to the entire engagement, not just the testing phase.
Some firms use a "proprietary methodology." That is fine if they can clearly explain how it maps to OWASP or PTES. If they cannot articulate their methodology in concrete terms, walk away. You can learn more about what good methodology looks like in our pentest tools and methodology guide.
The sample report test
Ask for a redacted sample report before signing. This single document tells you more than any sales call. Here is what to look for:
Executive summary: Is it written for business stakeholders? Does it quantify risk in business terms, not just CVSS scores? A good executive summary tells the CTO exactly what is broken and why it matters commercially.
Finding detail: Each finding should include a description, steps to reproduce, evidence (screenshots, request/response pairs), impact assessment, and remediation guidance. If the report just says "XSS found on login page" with no proof-of-concept, it is a scan report. Check our pentest report guide for what a proper report looks like.
Business logic findings: Automated scanners cannot find business logic flaws. Scanners do not understand that transferring money to yourself in an infinite loop is bad. If the sample report contains only generic OWASP Top 10 findings and zero business logic issues, the testers rely entirely on tools. Do not pay manual rates for automated scans.
Scoping and communication
A good pentest company asks hard questions during scoping. They demand API documentation, architecture diagrams, user roles, payment flows, and compliance requirements before quoting a price. If a firm quotes a flat fee after a 10-minute call with no technical questions, they are guessing. You will get a generic test.
During the engagement, you must receive regular status updates. At Simpa Labs, we use a dedicated Slack or WhatsApp channel per engagement. If we find a critical vulnerability mid-test, we flag it immediately. We do not wait for the final report two weeks later. Ask your vendor what their communication protocol looks like. For a breakdown of a solid engagement process, read how our pentest process works.
Retest policy
Remediation verification is not optional. After you fix the issues we find, someone needs to confirm the fixes actually work. A credible firm includes at least one round of retesting in the engagement price, or offers it at a clearly defined cost. If a vendor delivers a report and disappears, they are not a partner. They are a contractor.
Red flags to watch for
Over the years, we have seen patterns that reliably predict a bad engagement. Watch for these signals:
- No scoping call: They quote without understanding your system. This means the test will be shallow and generic.
- Guaranteed finding count: "We guarantee we will find at least 50 vulnerabilities." This incentivises padding reports with informational findings like "missing HTTP headers." Quality matters, not quantity.
- No retesting included: A report without remediation verification is half a service.
- Refusal to share a sample report: If they hide what the deliverable looks like, they are hiding low quality.
- No NDA or rules of engagement: A professional firm defines the legal boundaries of the test in writing before starting. No NDA means no professionalism.
Looking for a pentest partner who ticks every box on this list? Let's talk about your application.
Book a scoping callIndustry experience matters
Fintech is not generic IT. Your pentest vendor needs to understand payment flows, wallet systems, KYC/BVN verification, webhook callbacks, and the specific API vulnerabilities that hit payment platforms. A firm that primarily tests corporate intranets will miss the business logic flaws unique to financial services.
Ask for case studies or references in your vertical. If they test mobile money platforms, payment gateways, or lending platforms, they understand the threat model before day one.
Making your final decision
The right pentest company acts as an extension of your security team, not a vendor you deal with once a year. Evaluate them on technical depth, communication quality, methodology rigour, and their willingness to be transparent about how they work. The cheapest option is almost never the best. The consequences of a missed vulnerability far outweigh the savings. For a deeper look at pricing, check our pentest cost guide for Nigeria.
