Security and
regulatory compliance
We build every solution on a secure, resilient architecture, using rigorous SDLC processes that embed protection from the ground up. Our commitment to security is reinforced by compliance with PCI DSS, PSD2, PA-DSS, and GDPR, as well as adherence to ISO 27001 principles. We implement advanced encryption, apply secure coding practices, and conduct regular audits to proactively identify and eliminate risks.
Our proprietary Neontri Enterprise Application Framework (NEAF) provides a robust blueprint for modern banking systems. It offers a plug-and-play security foundation for mobile apps, enabling mutual TLS encryption, PKI certificate management, multi-factor authentication, protected data storage, and threat detection. It safeguards applications against tampering, jailbreaking, and unauthorized access while reducing development time and compliance risks.
Neontri enforces rigorous data privacy controls to protect sensitive banking information at every stage of development. All client data is safeguarded through strict NDAs, role-based access management, and multi-layered security protocols that prevent unauthorized exposure. We apply data minimization principles, isolate environments to prevent cross-contamination, and use encrypted channels for every data exchange.

Banking software development FAQ
Banking software development is designing, building, and maintaining the systems banks depend on — core transaction processing, payments, mobile and online channels, and the data infrastructure underneath all of it. These systems have to work under real regulatory pressure: PSD2, GDPR, PCI DSS. Neontri has been building in this space for 13+ years, with 100+ banking projects delivered.
It depends heavily on scope. A focused MVP can start in the low tens of thousands. A full core-banking or multi-channel platform can run into the hundreds of thousands. The biggest cost drivers are regulatory requirements, the number of third-party integrations, and how deep the security architecture needs to go. Neontri runs a discovery phase upfront so clients get a fixed estimate before the build begins — no surprises mid-project.
It’s re-architecting the system at the center of everything a bank does — moving from legacy infrastructure to modular, API-first platforms, often in the cloud. The tricky part is doing it without disrupting live operations. The typical sequence: system audit, roadmap, integration layer, then incremental migration. Neontri has built offloading and data-enrichment layers on top of existing cores — its Transaction Data Enrichment solution for PKO is one example — so modernization happens without pulling the rug out from under a running bank.
Both are baked in from the start, not added at the end. Neontri builds to PSD2, GDPR, PCI DSS, and AML/KYC requirements and holds ISO 27001 certification. The team co-developed a PSD2 open-banking hub that connects 300+ Polish banks with third-party providers — regulatory integration isn’t a specialty they picked up, it’s what a significant chunk of their work has been.
The track record is hard to argue with: 100+ projects, 98% client retention, and clients like Visa, PKO Bank Polski, and mBank. After 13 years building in one of the most demanding industries there is, the work speaks for itself.
Yes. This is much of what Neontri does — connecting new software to existing cores, payment rails, and third-party services via APIs and middleware. The PSD2 hub connecting 300+ banks is the clearest example. The data-enrichment and offloading layers built for PKO show the same pattern: extend what’s already running rather than replace it wholesale.
