Cybersecurity compliance for fintech and payments

No sector accumulates overlapping obligations faster than financial services. A payments company can simultaneously owe PCI DSS to the card brands, a prudential cybersecurity framework to its regulator, operational resilience obligations, privacy law duties, and customer security requirements from every bank it partners with. Run as separate programmes, this is unmanageable. Run from one control set, it is largely the same work reported several ways.

The stack

• PCI DSS - wherever cardholder data is stored, processed or transmitted. Scope is everything; reducing it is the highest-return activity available.
• Prudential frameworks - in Saudi Arabia the SAMA Cyber Security Framework, scored on maturity rather than implementation. Elsewhere the equivalent supervisory expectations.
• Operational resilience - DORA for EU entities, with ICT risk management, incident reporting, resilience testing and a register of ICT third parties.
• Privacy - GDPR, PDPL and equivalents; financial data is sensitive and often carries additional sector rules.
• Open banking and payment security standards where you operate under them.
• Partner bank requirements, which frequently exceed the regulatory baseline and arrive as contractual audits.

What is different about this sector

Maturity, not just implementation

Prudential frameworks such as SAMA CSF score maturity from 0 to 5. A control can be fully implemented and still score level 3 because nobody measures or reports its effectiveness. Building measurement into controls from the start is far cheaper than retrofitting it.

Third-party concentration is a supervised risk

Regulators increasingly ask not just whether you assessed a provider, but whether you could leave them. DORA makes exit strategies explicit for critical providers. Most fintechs discover their exit plan is theoretical the first time they write it down.

Incident reporting clocks are short

Sector regimes impose staged reporting on tight timelines, and contractual obligations to partner banks are often shorter still. The constraint is rarely detection - it is having a pre-authorised decision-maker who can notify without convening a committee.

Where fintech programmes struggle

• PCI scope creep - card data discovered in logs, exports, support tickets or call recordings outside the defined environment.
• Maturity plateau at level 3 because no KPIs or periodic reporting exist.
• Incomplete third-party registers, particularly the subprocessors behind direct suppliers.
• Exit plans that are aspirational rather than tested.
• Speed-versus-control tension - shipping fast while evidencing change approval, which is where fast-growing fintechs most often collect findings.
• Partner bank audits arriving unpredictably and consuming the same team as the regulatory cycle.

Sequencing that works

1. Reduce PCI scope first - tokenisation, redirect integrations and segmentation cut hundreds of applicable controls.
2. Build one control library and map every applicable framework onto it.
3. Add measurement early so maturity scoring is achievable, not retrofitted.
4. Complete the third-party register including fourth parties, then write real exit plans for the critical ones.
5. Pre-authorise incident notification with named decision-makers and prepared templates.
6. Automate evidence from your cloud and identity systems - engineering velocity makes manual evidence unsustainable.

Key takeaways

• Reduce PCI scope before assessing anything - it is the biggest lever.
• Maturity frameworks require measurement; build it in from the start.
• Exit strategies for critical providers are now supervised, not theoretical.
• One control library serves regulators, card brands and partner banks alike.
