A fintech's first supply chain program needs three records and three controls. The records are a software inventory, a register of third-party services, and an exception log. The controls are locked dependencies, protected build pipelines and a fast vulnerability triage path. Build in that order, and map each to the regulation your customers cite.
Why do fintechs feel this pressure early?
Banks and payment partners send security questionnaires before they sign. Regulators ask about third-party risk. Small teams ship quickly on open source and cloud services, so the dependency surface is large from day one while the security team may be one person.
Regulation names the problem directly. The EU's Digital Operational Resilience Act, Regulation (EU) 2022/2554, requires financial entities to maintain a register of information on all contractual arrangements for ICT services provided by third-party providers, so supervisors can see the whole picture. Its scope lists many entity types, including insurance and reinsurance undertakings. Other regimes, such as payment card rules, ask for software inventories as well. Check the current text of each framework that applies to you.
What are the three records?
Software inventory. For each service: repositories, languages, key dependencies, base images, where it runs, and who owns it. Generate dependency lists from lockfiles rather than writing them by hand.
Third-party register. Every cloud provider, payment processor, identity provider, analytics script and developer tool that touches customer data or the build. Record what data they see, the contract owner, the contact for incidents and the exit plan. This is the document regulators and partners ask for first.
Exception log. Where you accepted a risk: an unpatched dependency with no fix, a vendor without a report. Each entry needs an owner, a reason and a review date.
What are the three controls?
Locked dependencies. Commit lockfiles, install with the strict command in CI, and use a controlled registry or proxy. A fintech rarely needs a new package the same hour it is published, so a short delay on brand new versions is cheap insurance.
Protected pipelines. Require review for changes to pipeline definitions, keep deploy credentials out of jobs that run pull request code, use short-lived cloud credentials, and pin third-party build actions to immutable references. Anyone who can alter the pipeline can ship code to production, so treat it as a production system.
Fast triage. When an advisory appears, someone must answer "do we run it, and is it reachable?" in hours. That needs the inventory and a named owner. NIST's secure software development framework describes the practices: identify and confirm vulnerabilities on an ongoing basis, and analyze them to decide a response.
A constructed first quarter
Weeks one to three: list services and owners, generate dependency lists from lockfiles for the three most sensitive ones, and start the third-party register with every vendor that sees customer data. Weeks four to eight: lock and proxy dependencies, add scanning to pull requests, review pipeline permissions. Weeks nine to twelve: produce an SBOM per release for the sensitive services, run a tabletop where a widely used library has a critical flaw, and fix what the drill exposes.
What should you not do yet?
Skip buying a stack of overlapping tools before the inventory exists. Skip writing a long policy nobody reads. Skip chasing every low severity finding. Fix reachable, exploitable, internet-facing problems first.
What to do
- Name an owner and start the three records this week.
- Generate dependency lists from lockfiles for every service.
- Put installs behind a controlled registry and commit lockfiles.
- Lock down pipeline permissions and pin third-party actions.
- Add dependency scanning to pull requests with an agreed severity gate.
- Produce SBOMs for services that handle money or customer data.
- Run a tabletop drill and write down the gaps.
- Map what you have to the specific framework a partner or regulator names.
Safeguard offers dependency scanning, SBOM generation, reachability analysis and compliance automation that can help with the evidence side, and the free scan at gold.safeguard.sh/scan lets you try a dependency list in your browser. It does not certify you against any framework.
Quick check
Do we need an SBOM before our first bank customer?
Not always, but you need to answer questionnaire questions about dependencies. Generating SBOMs from lockfiles is cheap and answers most of them.
Is the third-party register only for EU firms?
DORA names it formally, but every fintech benefits from one, because partners and auditors in many regions ask the same questions.
