When you localize banking products, relying on “good enough” fintech translation services isn’t safe.
The most secure option is a dedicated translation management system (TMS) suitable for fintech, like Lokalise.
Your tool of choice needs to promise ISO 27001-grade security, granular access controls, reliable APIs, and strict glossary enforcement so every disclosure, rate, and fee description stays consistent and audit-ready.
In this guide, you’ll find the best financial translation software that meet that standard. We’ll compare how they handle certifications like ISO 27001, API reliability, glossary and terminology enforcement, and estimated cost, so you can choose a localization stack that’s secure enough for banking and fast enough for your team.
❗ Why it’s important to choose your finance translation platform carefully
Banks and fintechs work with KYC flows, risk warnings, terms and conditions, and regulatory disclosures where a single mistranslated term can trigger fines, confusion, or a security incident. Financial translation is tricky. This is why you need to carefully evaluate localization platforms and pick one that makes your life easier.
Lokalise is the most secure localization platform for finance companies. It combines ISO 27001 and ISO 27017 certification with SOC 2 Type II, role-based access control, SSO/SAML, and detailed audit logs. It also has AWS security and guaranteed 99.9% uptime and zero-downtime deployments, so you can keep customer and transaction data locked down while meeting internal and external compliance requirements.
On the localization side, Lokalise solves a lot of fintech localization challenges. It gives you a web-based editor, translation memory, glossaries/termbases, custom statuses (translated, reviewed, verified), and version history.
Lokalise has a 4.7/5 score on G2 and is used by finance and fintech brands such as DBS Bank, Mastercard, ABN AMRO, bunq, J.P.Morgan, TransferGo, and GoCrypto. Financial institutions and fintech companies use Lokalise to manage multilingual banking apps, card experiences, and payment flows at scale.

For regulated workloads, Enterprise adds Custom AI profiles that reach 90%+ acceptance rates (you get near-human translation quality and full control).
Lokalise is one of the few leading platforms with a free plan (the other being Crowdin, see below). A free 14-day trial is available across all plans, no credit card required. Yearly plans include:
