At Ozone API security is our top priority. It has been embedded into our culture, our development process, and our technology from day one. See more here.
At Ozone API security is a foundational principle. It has been embedded into our culture, development process, and our platform from day one. We meet the highest security standards including FAPI (1.0/2.0), CIBA, ISO27001:2022, SOC2 Type 2, and IASME. Read more.
FAPI (Financial-grade API Security Profile) is a special security standard created specifically for financial services that ensures open banking platforms meet the required rigorous security requirements. It’s important because it provides an extra layer of protection for financial data sharing, requiring stronger security measures than regular websites or apps to protect against fraud and cyber attacks. Banks and regulators require FAPI compliance to ensure that any company handling financial data meets the highest safety standards, giving customers confidence that their money and personal information are properly protected. Ozone API maintains FAPI certification to ensure our platform meets these strict financial security requirements.

No. you can choose to expose only the interfaces required by your regulatory obligations or business needs.
APIs (or Application Programming Interfaces) serve as bridges between software systems, enabling them to exchange information and functionality seamlessly. They define the methods and data formats for communication, facilitating integration without requiring developers to understand internal workings. By adhering to specific rules and protocols, APIs empower developers to access features or data from other applications or services, fostering interoperability and innovation in the digital realm.
Open banking is the plumbing that connects financial services. Instead of building custom integrations for every bank, standardised open APIs can be used to access financial data and services with the data owner’s (consumer’s) consent.
Open banking creates a regulated ecosystem where innovation can flourish while maintaining security and consumer protection. It’s the foundation for a more competitive, innovative financial services market.
Instead of consumers logging into multiple banking apps separately, they can safely share their financial data with trusted third-party services through secure, standardised APIs.
Banks can use open banking to connect with other financial institutions and businesses, providing new and enhanced products and services for their customers whilst maintaining full control and security.
Successful open banking ecosystems are based on standards that let banks, fintechs, and other financial services share data securely with customer permission.
From a technical perspective, open banking provides standardised REST APIs that eliminate the need for screen scraping or custom bank integrations.
Yes, open banking ensures the secure sharing and consumption of data, it can drive revenue growth for financial institutions and enable inclusion for those underserved by traditional financial products. Whether you are a bank, third party provider, or a consumer, there are multiple benefits available.

- Improve core offerings
- Increase customer loyalty
- Create new revenue streams
- Accelerate innovation to embed financial experiences in multiple ways
- Offer increased protection against fraud
- Reduce operational costs
Third Party Providers
- Generate revenue through new products and services
- Frictionless access to open banking APIs
- Reduce the cost of partnerships and enable faster onboarding
- A more robust, reliable and secure API based technical environment to connect to banks and financial institutions
Consumers and Businesses
- Smooth and consistent user journeys for exceptional experiences
- Increased financial inclusion and access to relevant products
- Brand new ways to manage their financial health
- Reduced friction for payment and credit journeys
- Unlock truly embedded financial experiences
Open banking works by sharing information, or making payments, through secure digital connections between third party providers (such as a wealth management app) and banks or other financial institutions. Information is only shared, and payments made with the explicit consent of the consumer.
Here’s the process:
- The consumer chooses to connect an app (like a budgeting tool) to their bank account
- They provide permission by logging into their bank and saying “yes, this app can see my data”
- Their bank shares only the specific information that has been agreed to share
- The app uses this information to provide the consumer with services (like tracking spending)
- Consent can be revoked at any time, and the connections, or data sharing will cease
Open banking will never ask for a consumer’s password or bank log in credentials, ensuring that the process is secure, and can be trusted by consumers.
Open banking has been designed with security at the core. There are a number of layers of security to ensure customers and their data and accounts are protected. A critical layer is customer consent. Access is only provided based upon the customer providing explicit and very granular consent. The API Standards and regulatory framework also incorporate many security measures, for example ensuring that only authorised third parties are allowed to connect to banks APIs. And ensuring customers go through strong customer authentication to ensure it is the real customer authorising consent. Every interaction only happens once the strict security standards are met.
This is significantly stronger than historic methods of data sharing in which customers shared their log in credentials to a third party to allow them to access an account on the customers behalf (sometimes known as screen scraping)
Open banking transforms how financial data is shared, it replaces old, insecure methods like screen scraping with fast, secure, standardised APIs. Customers stay in control of their data whilst banks can innovate and create new financial services.
Open banking APIs enable secure data sharing between banks and authorized third parties based on explicit consent from the customer. Customers authenticate directly with their bank, authorize what data will be shared, and the bank provides only authorized information through encrypted connections. The system maintains audit trails and allows customers to revoke access anytime while meeting regulatory security requirements.
Open banking is a key capability for modern banks and represents a big strategic opportunity. Banks typically think through the following big questions. Firstly what regulatory requirements do I need to meet? Secondly how do I best meet my customers needs. Thirdly how do I use open APIs to create value and grow the business.
The next question from there is how best to implement open APIs. Contact our experts to to discuss how Ozone APIs platform can accelerate your strategy across all aspects
Major banks worldwide use open banking, from traditional institutions like Deutsche Bank and Santander in Europe to challenger banks like Monzo and N26 that built open banking into their core offerings. The adoption spans thousands of banks such as Europe, Brazil, UK, Australia and Singapore, where open banking is mandated by the regulator and the banks have to have open banking APIs, and then there’s regions that aren’t mandated such as US banks, but who are also implementing open banking capabilities voluntarily. Credit unions, building societies and other financial institutions are also adopting these standards to remain competitive and offer enhanced digital services.
Financial planning apps that connect to your bank accounts, investments, pensions, and insurance policies to provide complete financial health views with personalised advice. The app analyses spending patterns, investment performance, and coverage gaps to recommend specific actions like rebalancing portfolios or adjusting insurance. This covers your entire financial ecosystem beyond just bank accounts and payments.
Open banking focuses on bank account data and payment services, while open finance expands to include all financial services such as investments, insurance, pensions, and credit products. Both use the same secure, consent-based data sharing principles, but open finance enables customers to share their complete financial portfolio with authorised providers for more comprehensive financial management.
