FinTech Cybersecurity & Penetration Testing

FinTech spans digital payments, e‑wallets, neobanking, lending platforms, investment apps, open banking aggregators, and embedded finance. These businesses operate at global scale, handle sensitive financial and personal data, integrate with banks and PSPs, and rely on APIs, cloud services, and mobile applications to deliver seamless, compliant user experiences. Any breach, fraud incident, or service outage can trigger regulatory scrutiny, harm customer trust, and materially impact revenue and valuations.

7Camber delivers customised penetration testing and continuous vulnerability management for FinTech organisations in more than 20 countries. Our highly certified team brings 10+ years of hands‑on experience across Regulatory pentests (PCI‑DSS, ISO, DORA, TIBER TLPT) and Elective pentests (API, network, Wi‑Fi, web app, mobile app), backed by clear reporting, remediation guidance, and board‑safe assurance.

What the FinTech Industry Deals With

Digital payments & settlement: Card payments, ACH/SEPA, instant payments, remittances, and chargeback flows.
Open banking & API aggregation: PSD2/OB APIs, consent, data sharing, and secure account linking.
Digital identity & onboarding: KYC/AML, document verification, biometrics, fraud checks, and risk scoring.
Investment & lending platforms: Orders, portfolios, loan origination, underwriting models, and customer disclosures.
Cloud‑native scale: Microservices, serverless functions, CI/CD pipelines, observability, and third‑party SDKs.
Compliance‑heavy operations: Security controls tied to PCI‑DSS, ISO 27001, DORA (EU), and—in some cases—TLPT (TIBER) requirements.

Key Online & Cyber Risks (FinTech)

Payment Fraud & Business Logic Abuse – Weak validation, insufficient anti‑automation, and exploitable flows lead to unauthorised transactions, chargebacks, and revenue loss.
Account Takeovers (ATO) – Credential stuffing, session hijacking, poor MFA, and social engineering expose accounts and PII/financial data.
API Exploitation – Over‑permissive endpoints, IDOR, JWT/OAuth misconfigurations, rate‑limit bypass, and mass data harvesting threaten confidentiality and integrity.
Open Banking Risks – Mismanaged consent, insecure token handling, and weak authorisation across partner APIs create high‑impact data exposures.
Data Breaches & Privacy Failures – Misconfigurations, insecure storage, and flawed key/secret management expose PII, PCI data, and analytics signals.
Cloud & CI/CD Misconfigurations – Overexposed buckets, permissive IAM roles, vulnerable pipelines, and inadequate secret rotation enable lateral movement and supply‑chain compromise.
DDoS & Availability Attacks – Targeting public portals and API gateways disrupts onboarding, payments, and trading at peak times.
Mobile App Tampering – Reverse engineering, insecure local storage, and weak certificate pinning compromise tokens, logic, and user trust.

Relevant 7Camber Services for FinTech

Regulatory Penetration Testing (Compliance)

PCI‑DSS Penetration Testing
For platforms handling cardholder data, our PCI‑DSS pentests assess applications, APIs, and networks to validate controls, reduce scope, and support audit readiness.
ISO 27001 Penetration Testing
Validate the effectiveness of your ISMS and technical controls, identify real‑world gaps, and evidence continuous improvement for surveillance audits and certification.
DORA Readiness Testing
For EU‑connected FinTechs and financial entities, we test operational resilience, incident response preparedness, third‑party risks, and control maturity aligned to DORA objectives.
TIBER TLPT (Threat‑Led Testing)
Where TLPT applies, we simulate realistic adversaries to probe detection and response capabilities, strengthen resilience, and align with regulator expectations.

Outcome: Clear findings mapped to regulatory frameworks, prioritised remediation plans, and audit‑friendly artefacts—helping you satisfy standards, laws, and regulations while improving day‑to‑day security.

Elective Penetration Testing (Security Posture)

Web Application Pentesting
Secure onboarding portals, dashboards, payment pages, and customer support modules against OWASP Top 10, session weaknesses, and business logic flaws.
API Pentesting
Harden authentication and authorisation, validate consent flows, rate‑limiting, input handling, and protect against IDOR, injection, mass assignment, and enumeration.
Mobile Application Pentesting
Assess iOS/Android apps for secure storage, token protection, certificate pinning, transport security, and tamper resistance.
Internal & External Network Pentesting
Identify misconfigurations, legacy services, privilege escalation paths, and lateral movement across corporate and production environments.
Wi‑Fi Pentesting
Validate wireless segmentation, encryption, captive portals, and rogue AP detection across offices, branches, and event spaces.

Outcome: Actionable insights to reduce exploit paths across payments, onboarding, APIs, and mobile—protecting customer data, revenue, and brand reputation.

Scanning

Vulnerability Assessments (snapshot)
Rapid visibility of exposed services and known CVEs via automated tooling—ideal as a baseline or pre‑release hygiene check.
Vulnerability Monitoring (monthly/quarterly)
Scheduled assessments with trend reporting, fix validation, and remediation follow‑up—staying ahead of new releases, infrastructure changes, and emerging threats.

Outcome: Measurable risk reduction, improved patch cadence, and fewer surprises during peak transaction periods.

Why Cybersecurity Matters for FinTech

Protect customer trust: Strong authentication, privacy, and reliable services drive adoption and retention.
Safeguard revenue: Reduce payment fraud, ATO, and abuse of critical business flows.
Ensure availability & resilience: Maintain uptime across portals and gateways during high‑volume events.
Meet compliance obligations: PCI‑DSS, ISO 27001, DORA, and (where relevant) TIBER TLPT provide confidence to regulators, partners, and investors.
Enable secure scale: Security‑by‑design accelerates product delivery and partner integrations without accumulating material risk.

Our Testing Approach (How We Work)

Scoping & Objectives
Define data sensitivity, flows (payments, onboarding, consent), compliance needs, and test constraints (production‑safe vs staging).
Threat Modelling
Identify adversaries, high‑value assets (PII, PCI, tokens, secrets), attack surfaces (web, mobile, APIs, cloud, CI/CD).
Execution
Combine manual expertise with tooling for authenticated/unauthenticated testing, exploit validation, and evidence collection.
Clear Reporting
Prioritised findings, risk ratings, proof‑of‑concepts, affected components, and business impact—mapped to OWASP, PCI‑DSS, ISO controls.
Remediation Support
Practical fixes, configuration hardening, secure design patterns, and developer enablement.
Re‑Testing & Assurance
Validate mitigations, provide executive summaries, and recommend monitoring/alerting improvements.

Benefits You Can Expect

Board‑safe visibility with risk‑based findings and clear business impact.
Developer‑friendly guidance with reproducible steps and recommended controls.

FAQs (FinTech Security)

Q1: We already do Elective pentests. Do we still need Regulatory pentests?
Yes. Regulatory pentests evidence compliance (PCI‑DSS, ISO 27001, DORA/TLPT where applicable) and are often mandatory. Elective pentests complement compliance by focusing on your unique attack surfaces and business logic.

Q2: Can testing affect live services?
We plan test windows and guardrails to avoid disruption. Where possible, we target staging and perform production‑safe assessments with agreed limits and monitoring.

Q3: How often should FinTechs test?
Typical cadence: major releases, infrastructure changes, partner integrations, and at least annually for comprehensive pentests; monthly or quarterly for vulnerability monitoring.

Q4: What deliverables will we receive?
Detailed reports with prioritised findings, risk ratings, reproducible steps, recommended fixes, and executive summaries—plus re‑testing to validate remediation.

Q5: Do you assess cloud and CI/CD security?
Yes. We review IAM, networking, storage, secret management, pipeline hardening, and supply‑chain risks across SDKs and dependencies.
