Fintech security needs its own program because a financial startup handles customer financial data and payment flows from its first customer, and rules such as the FTC Safeguards Rule and PCI DSS apply by activity, not company size. Building controls early is cheaper than retrofitting them under due diligence.
Which rules apply to a young financial company?
It depends on what you do, so check with counsel. Two commonly relevant sources are public. The FTC Safeguards Rule, at 16 CFR 314.4, lists the elements of an information security program for covered financial institutions. PCI DSS applies to entities that store, process or transmit cardholder data.
Neither rule asks how many employees you have. A five person payments startup that stores card data is in the same scoping conversation as a large processor, just with a smaller system to examine.
What does the Safeguards Rule actually require?
The text is specific. You designate a Qualified Individual to oversee the program. You base the program on a written risk assessment. You implement safeguards that include access controls limiting users to the customer information they need, encryption of customer information in transit over external networks and at rest, multi-factor authentication for anyone accessing an information system unless the Qualified Individual approves an equivalent control in writing, and procedures for secure disposal.
It also asks for secure development practices for in-house applications, change management, and monitoring and logging of authorized user activity. For testing, it requires continuous monitoring or, absent that, annual penetration testing and vulnerability assessments at least every six months. Staff need security awareness training updated for identified risks.
That list reads like an engineering backlog, which is the useful way to treat it.
Why does scoping matter so much for payments?
The PCI Security Standards Council's scoping guidance says scoping means identifying people, processes and technologies that interact with or could affect the security of cardholder data. Segmentation adds controls that separate systems with different security needs, and it can reduce the number of systems in scope. It can use firewalls and router configurations, network configurations that prevent communication between subnets, or physical access controls.
The council also warns that systems connected to the cardholder environment are in scope, and that being out of scope is not a reason to leave a system unprotected.
A constructed example: a lending app routes card payments through a hosted payment page so card numbers never touch its servers, and keeps its customer database in a separate network segment from the marketing site. At audit time the in-scope footprint is small and easy to explain. If card numbers had flowed through the shared application database, every connected system would have been dragged into scope.
What do founders usually skip?
Three things. First, a data inventory: you cannot encrypt or dispose of data you have not listed. Second, vendor review: the Safeguards Rule expects you to evaluate externally developed applications you use for customer information. Third, written decisions: the rule repeatedly asks for written risk assessments and written approvals, and an undocumented control is hard to prove.
How to check or apply this
- Name a Qualified Individual and record who oversees that person.
- Inventory every place customer financial data and cardholder data are stored or pass through.
- Write a short risk assessment: threats, existing controls and what you will accept or fix.
- Turn on multi-factor authentication for every system that touches customer information.
- Encrypt data at rest and in transit, and set a disposal schedule.
- Reduce PCI scope by using hosted payment components and separating networks.
- Schedule vulnerability scans at least every six months and a yearly penetration test unless you have continuous monitoring.
- Train staff and log training completion.
Quick check
Does PCI DSS apply if I never see card numbers?
It depends on how you take payments. Hosted or redirected payment designs can shrink scope considerably, but confirm your obligations with your acquirer or a qualified assessor.
Is segmentation required by PCI DSS?
PCI's guidance describes segmentation as a way to reduce scope, not a mandate. Without it, your whole connected network is in scope.
