Fintech & Banking : What PCI DSS, DORA, and ISO 27001 Actually Mean for You

Banks and fintechs sit at the intersection of money and data — which makes them a permanent target. If you run a financial services business, "we're compliant" was never a single checkbox, and it's gotten less single every year. It's a stack of overlapping frameworks, each covering a different slice of your risk, each on its own renewal clock, each enforced by a different regulator. Miss one and you don't just fail an audit — you lose the enterprise partnerships and banking-as-a-service relationships that depend on it.

Here's what actually applies, why it applies to you specifically, and what closing the gap looks like in practice.

The Threat Landscape

The core risks in this sector haven't changed much in kind — payment fraud, account takeover, API abuse — but they've changed in scale and in how regulators think about them. Increasingly, the question isn't just "were you attacked" but "how well did the business keep running when you were." A breach at a financial institution is never only a data problem. It's simultaneously a liquidity problem, a trust problem, and a regulatory problem, and all three move fast once the first headline hits.

There's also a third-party dimension that's harder to control than it sounds. Your core banking platform, your payment processor, your cloud host, your fraud-detection vendor — every one of them is part of your attack surface, whether or not you're auditing them on any regular cadence. Regulators have noticed this too, which is why the compliance bar has shifted from "do you have controls documented" to "can you prove those controls held up under a real incident." Paper policies don't satisfy that bar anymore; tested, evidenced resilience does.

The Compliance Stack

DORA — the one to know right now

The EU's Digital Operational Resilience Act isn't a future concern to plan around — it's been fully in force since January 17, 2025. What catches most non-EU fintechs off guard is scope: DORA doesn't stop at EU-headquartered institutions. It extends to any third-party ICT vendor serving an EU-regulated financial entity, regardless of where that vendor is based. If you're a fintech with even one EU client relying on your infrastructure, DORA likely already applies to you — and unlike a lot of compliance regimes, it specifically requires resilience testing, not just a policy binder that says you're resilient. See DORA Compliance Services | GTIS for how that testing gets structured in practice.

The rest of the stack

DORA doesn't replace the other frameworks — it sits alongside them, and each one is doing a different job.

PCI DSS 4.0.1 governs how you store, transmit, and process card data specifically. It's enforced not by a government regulator but by the card networks and your acquiring bank, and it's non-negotiable the moment you touch a card number — there's no size threshold below which you're exempt. For a deeper walkthrough of what changed in the newest version, see PCI DSS 4.0.1 Compliance | GTIS.

ISO 27001 and SOC 2 aren't legally mandated in most jurisdictions, but they've become the de facto price of entry for working with enterprise clients and banking partners. They cover your information security management program broadly — not just card data, but how you handle risk, access, and incident response across the business. Enterprise partners increasingly won't sign a contract without one or the other.

AML obligations are about fraud and money-laundering detection and reporting, enforced by your national financial regulator (RBI, ECB, FinCEN, and equivalents elsewhere). This is less a technical security framework and more a monitoring-and-reporting discipline, but it still has real infrastructure requirements — transaction monitoring, suspicious activity reporting, know-your-customer checks.

GDPR and DPDP cover personal data handling and apply based on whose data you're touching, not where you're based. If you have EU customers, GDPR applies; if you have Indian customers, DPDP applies — regardless of where your company is headquartered.

What the Business Case Actually Calls For

Knowing which frameworks apply is the easy part. Building the operational capability to satisfy them — and keep satisfying them — is where most teams get stuck. In practice, that capability tends to break down into a handful of concrete services:

• PCI DSS certification + VAPT — you cannot process a single card transaction without proving the environment around it is secure, and that proof has to be re-earned, not assumed.

• SOC (Security Operations Center) + SIEM — fraud and account takeover happen in real time, which means you need eyes on the network around the clock, not a quarterly review.

• MDR (Managed Detection & Response) — the right fit for institutions that need rapid containment but don't have the headcount to staff a threat-hunting team in-house.

• Cyber Risk Assessment + ISO 27001 consulting — the evidence trail both regulators and enterprise partners want before they'll integrate with you: a formal ISMS, not a verbal assurance.

• CISO-as-a-Service — executive-level security governance for fintechs that need the role filled but aren't yet at the size (or the budget) to hire a full-time CISO.

None of these are optional extras layered on top of "real" compliance work — they're what compliance work actually looks like once you get past the framework names.

The GTIS Approach

For financial institutions, GTIS positions its value around correlating asset criticality, threat intelligence, and exploitability — the idea being that a bank doesn't need more alerts, it needs to know which of its 500 open findings are the five that could actually cause a breach. Their CISO-as-a-Service model is built around that same logic: someone fluent in both the regulatory language (DORA, PCI DSS) and the technical stack, sitting between your compliance team and your security engineers so the two groups stop working off different priority lists.

Given their partnerships with SIEM and detection vendors like Splunk, CrowdStrike, and Tenable, the pitch is vendor-neutral integration — they work with whatever stack you already have rather than pushing a rip-and-replace. For a sector where regulators (RBI, ECB) and enterprise partners both demand documented proof of controls, that combination of technical depth and audit-ready reporting is arguably the whole value proposition.

Frequently Asked Questions

Does DORA apply to fintechs outside the EU? Yes, if you provide ICT services to an EU-regulated financial entity. DORA's third-party risk provisions extend to vendors regardless of where they're headquartered.

Is PCI DSS enough on its own for a fintech company? No. PCI DSS only covers cardholder data. Most fintechs also need ISO 27001 or SOC 2 to satisfy enterprise partners, and increasingly, DORA-related resilience requirements if they serve EU clients.

How often does PCI DSS certification need to be renewed? Annually, with quarterly ASV scans required in between to maintain compliance status.

What happens if I only satisfy one framework and not the others? You'll likely still fail to close enterprise or banking-partner deals. Most large partners now require proof across more than one framework — PCI DSS for card data plus ISO 27001 or SOC 2 as a general trust signal is the common minimum bar.

Get Your Compliance Gaps Mapped

DORA, PCI DSS, and ISO 27001 don't move on the same timeline, and figuring out which applies to your specific business model — and in what order to tackle them — is where most financial institutions get stuck.
