Cybersecurity for Fintechs: Which Regulations Actually Apply

A fintech does not inherit one tidy compliance framework. Its obligations are assembled from its activities, the data it touches, the licenses it holds, and the partners it relies on. Map those four inputs correctly and the regulatory picture stops being a guessing game.

Most fintech founders ask the wrong question. They ask "are we regulated?" as if the answer were a binary, when the real answer is "by whom, for what, and to what depth." A lending app, a money transmitter, a card issuer riding a sponsor bank, and a B2B treasury tool each face a different stack of rules even when they share the same Series A investors and the same React frontend. Z Cyber works as a cybersecurity operating partner for companies in exactly this position. We map obligations to the business, then run the program on Glance, our AI-native GRC platform, so the founding team can keep building instead of becoming part-time compliance officers.

This guide walks through the regimes that most often apply to U.S. fintechs, how to tell which ones bind you, and where the common traps are. It is a map, not legal advice. The point is to replace vague anxiety with a specific, testable list of obligations.

Start with four inputs, not a framework

The cleanest way to scope a fintech's cybersecurity obligations is to inventory four things before you reach for any acronym.

Activities. What does the company actually do? Lending, money transmission, deposit-taking through a partner, card issuing, payment facilitation, investment advice, and crypto custody each trigger different rules. Marketing copy ("we help you manage money") does not determine this. The mechanics of the money movement do.

Data. What sensitive data flows through your systems? Cardholder data, bank account and routing numbers, Social Security numbers, government IDs from KYC, and consumer financial account information each carry their own obligations. The presence of cardholder data alone pulls in an entire standard.

Licenses. What charters, licenses, or authorizations does the company hold, or operate under? A state money transmitter license, a NYDFS authorization, a BitLicense, or a lending license each attaches specific security expectations.

Partners. Whose rails are you on? A sponsor bank, a card network, a BaaS provider, or an enterprise customer will push contractual security requirements down to you, often stricter than what the law alone would demand.

Hold those four inputs in mind as we walk the regimes below.

The GLBA Safeguards Rule: broader than most founders expect

The single most under-appreciated obligation for non-bank fintechs is the FTC's Safeguards Rule under the Gramm-Leach-Bliley Act. Founders assume GLBA is a "bank thing." It is not. The FTC enforces the Safeguards Rule against any "financial institution" under its jurisdiction, and the definition is deliberately broad. It captures many companies that are "significantly engaged" in financial activities even though they are not banks: many non-bank lenders, money transmitters, certain payment firms, and businesses that provide account-servicing or similar financial functions.

If the Safeguards Rule applies, you owe a written information security program with specific elements. Among them: a designated Qualified Individual responsible for the program, a written risk assessment, access controls, encryption of customer information in transit and at rest where feasible, multi-factor authentication for systems holding customer information, a written incident response plan, oversight of service providers, and periodic reporting to a governing body. This is not a checkbox PDF. It is an operating program that has to be maintained and evidenced.

The practical failure mode is treating the Safeguards Rule as theoretical until an incident or a partner due-diligence questionnaire forces the issue. By then you are reconstructing a program under pressure. Z Cyber stands up the written program, fills the Qualified Individual function, and operates the controls on Glance so the evidence exists before anyone asks for it.

PCI DSS: triggered by card data, not by company type

If your fintech stores, processes, or transmits payment card data, the Payment Card Industry Data Security Standard applies. PCI DSS is not a law. It is a contractual standard imposed by the card networks and your acquirer or processor, and it binds through your merchant or processing agreements. The trigger is the data, not your charter.

The most valuable PCI move is reducing scope. Every system that touches cardholder data falls inside the Cardholder Data Environment, and everything in the CDE inherits the full weight of the standard. Tokenizing card data, outsourcing capture to a compliant processor, and segmenting networks can shrink the CDE dramatically and lower both cost and risk. Our walkthrough of PCI DSS v4 requirements and CDE scoping covers how to draw that boundary and which validation path fits your transaction volume.

If you have engineered card data out of your environment entirely, for example by using a processor's hosted fields so card numbers never touch your servers, your PCI obligations shrink to a much lighter validation. That architectural decision is worth making deliberately and early.

NYDFS Part 500: license-driven, and it reaches fintechs

New York's cybersecurity regulation, 23 NYCRR Part 500, binds any "covered entity" operating under a NYDFS license or authorization. That population includes many fintechs: lenders licensed in New York, money transmitters, and virtual-currency businesses operating under a BitLicense. If you hold a NYDFS authorization, Part 500 is not optional, and recent amendments have raised the bar with stricter governance, MFA, asset inventory, and incident-notification timelines.

Part 500 expects a documented cybersecurity program and policy, a designated CISO who reports to senior governance, risk assessments, MFA, encryption, penetration testing and vulnerability management, audit trails, and prompt notification of qualifying cybersecurity events. Senior officer certification of compliance is a recurring obligation, which means an executive is personally attesting that the program is real. Our NYDFS 500 compliance checklist lays out the current requirements in sequence so you can self-assess before a regulator does.

The trap here is geographic denial. Founders assume a New York rule only matters if they are headquartered in Manhattan. The binding fact is the license, not the office address. A money transmitter authorized to operate in New York is in scope regardless of where its engineers sit.

State money transmitter laws and the partner-driven layer

Beyond the headline federal and New York regimes sit two more layers that quietly drive most of the day-to-day work.

State money transmitter laws. If you move money on behalf of others, you likely need money transmitter licenses across the states where you operate, and many of those licenses carry their own security, recordkeeping, and examination expectations. The compliance burden here is cumulative across states and tends to grow as you expand.

Bank partnership and sponsor requirements. Fintechs that operate through a sponsor bank, the Banking-as-a-Service model, almost always face the strictest practical requirements, and they arrive through contracts rather than statutes. Banks are subject to interagency guidance on managing risk from third-party relationships, and that expectation flows downhill to you. Your sponsor bank will require bank-grade controls, a mature third-party risk posture, the right to audit, evidence of testing, and timely incident reporting. In practice, the sponsor's security addendum is often a tougher document to satisfy than any single regulation. Z Cyber's work with financial services clients frequently centers on passing exactly this kind of sponsor-bank and enterprise due diligence.

SOC 2 and the rest of the stack: market expectations and oversight

Two more items round out the picture. Neither is a cybersecurity statute in the way GLBA or Part 500 is, but both shape what you must build.

SOC 2. A SOC 2 report is a market expectation, not a law. No regulator requires it. Yet enterprise customers and bank partners frequently require it before they will sign, which makes it a de facto gate for revenue. Treating SOC 2 as the backbone of your control program is sensible because its Trust Services Criteria overlap heavily with what GLBA, Part 500, and sponsor banks already demand. Our SOC 2 compliance guide explains how to scope a Type I or Type II engagement so one program satisfies multiple audiences.

CFPB and SEC. If you offer consumer financial products, the Consumer Financial Protection Bureau has supervisory and enforcement reach over your conduct, including data-handling practices. If your company is a public registrant, SEC rules on cybersecurity risk management and incident disclosure apply at the corporate level. Most early fintechs will not be public, but consumer-facing products should keep CFPB expectations in view.

A starting map from activity to likely regimes

The table below is a starting point, not a determination. Your exact obligations depend on the specifics of your licenses, data flows, and partner contracts. Use it to form a hypothesis, then validate each row.

Fintech type	Likely regimes to scope
Non-bank consumer lender	GLBA Safeguards Rule, state lending and money transmitter laws, NYDFS 500 if NY-licensed, CFPB oversight, SOC 2 (customer-driven)
Money transmitter / payments app	GLBA Safeguards Rule, state money transmitter laws, NYDFS 500 if NY-licensed, PCI DSS if card data is handled, SOC 2
Card issuer / program via sponsor bank (BaaS)	Sponsor-bank contractual controls and third-party risk requirements, PCI DSS, GLBA-aligned program, SOC 2
Virtual-currency / crypto business	NYDFS 500 and BitLicense if NY-authorized, state money transmitter laws where applicable, GLBA where it applies, SOC 2
B2B financial software (no money movement)	SOC 2 as the primary gate, PCI DSS only if card data is processed, GLBA only if acting as a covered service provider

Read the table as a prompt for diligence. A lender that has engineered card data out of its stack drops PCI. A payments app with no New York license drops Part 500. The work is confirming each row against your actual operations.

Turning the map into a running program

Knowing which regimes apply is the easy half. The hard half is building one coherent program that satisfies all of them at once, keeping it current as the regulations and your business change, and producing evidence on demand when a sponsor bank, an enterprise buyer, or a regulator asks. Run separately, GLBA, PCI, Part 500, sponsor-bank addenda, and SOC 2 generate enormous duplicated effort. Run as a single control set mapped to multiple frameworks, the overlap becomes leverage.

That consolidation is the core of how Z Cyber operates. We map your obligations to your activities, data, licenses, and partners. We design one control program that covers every applicable regime, implement it, and run it on Glance, where each control maps to the frameworks it satisfies and the evidence is collected continuously rather than scrambled together before an audit. You get a dedicated security team rather than a tool you have to staff yourself.

Frequently asked questions

Does the GLBA Safeguards Rule apply to fintechs? Often, yes. The FTC enforces the Safeguards Rule against any "financial institution" under its jurisdiction, and the definition is broad enough to capture many non-bank fintechs, including many lenders, money transmitters, and certain payment and account-servicing firms. If it applies, you must maintain a written information security program with a designated Qualified Individual, a risk assessment, access controls, encryption, MFA, and an incident response plan. The way to know is to test your specific activities against the definition rather than assuming GLBA is only for banks.

Do fintechs need PCI DSS? Only if they store, process, or transmit payment card data. PCI DSS is a contractual standard imposed by the card networks, not a law, and the trigger is the data. A fintech that has engineered card data out of its environment, for example by using a processor's hosted fields, can reduce its PCI obligations to a much lighter validation. A fintech that touches cardholder data directly faces the full standard, scoped to its Cardholder Data Environment.

Does NYDFS 500 apply to fintechs? It applies to any entity operating under a NYDFS license or authorization, which includes many fintechs: New York-licensed lenders, money transmitters, and virtual-currency businesses under a BitLicense. The binding fact is the license, not where the company is headquartered. If Part 500 applies, you owe a documented cybersecurity program, a designated CISO, MFA, encryption, testing, audit trails, qualifying-event notification, and recurring senior-officer certification.

What cybersecurity compliance do fintechs need to sell to banks? Selling to or through banks usually means meeting bank-grade controls and third-party risk expectations that flow down from interagency guidance, plus, in most cases, a SOC 2 report. A sponsor bank's security addendum will typically require a mature control program, a right to audit, evidence of testing, and timely incident reporting. SOC 2 is the most common gate because its Trust Services Criteria overlap with what banks and enterprise buyers already expect, so one well-scoped program can satisfy multiple audiences at once.
