10 Ways Open Banking is Fighting Fraud in Financial Services

Why Financial Fraud Persists

Fraud is evolving fast. As more services go digital, the surface area for attackers expands. Consider just a few of the most common threats:

• Credential stuffing and phishing: Fraudsters gain access to banking details through compromised logins
• Account takeover: Once inside, bad actors can siphon off funds or data
• Unauthorised data access: Especially risky when third parties store customer credentials to "scrape" bank data

Traditional approaches such as screen scraping or password-based access are not only outdated but inherently insecure. This is where open banking rewrites the rules.

Open Banking: Built for Security

At its core, open banking is about secure, consent-driven data sharing between banks and accredited third parties using APIs. That means:

• No passwords shared. Users never hand over login credentials
• Strict accreditation and compliance. Only regulated data recipients can access data
• Clear consent flows. Customers know exactly what is being shared, and for how long

This is not just a better customer experience. It is a fundamentally safer model.

10 Ways Open Banking Reduces Fraud

1. Eliminates Screen Scraping

Screen scraping forces users to share their bank login credentials with third parties, which is a risky move. Open banking replaces scraping with token-based, read-only API access. This keeps credentials safe and banks in control.

2. Consent as a Security Layer

Data sharing only happens with explicit, time-bound consent. Consumers can see which parties have access to their data and revoke it at any time. That transparency helps stop unauthorised access.

3. Real-Time Data Enables Real-Time Risk Detection

Open banking APIs offer real-time access to transaction and account data, enabling smarter and faster fraud detection. Financial institutions can flag anomalies as they happen, instead of waiting for delayed batch reports.

4. Accredited Ecosystems Limit Risky Access

Only licensed and vetted third parties can operate in open banking environments such as Australia’s CDR or the UK’s OBIE. This tightly controlled ecosystem prevents bad actors from gaining access.

5. Decentralised Data Reduces Single Points of Failure

Open banking decentralises data access using purpose-specific APIs. Unlike traditional systems with large centralised data stores, this reduces the impact of any potential breach and lowers incentives for attackers.

6. Full Audit Trails for Every Interaction

Every consent, data request, and API call is logged. These comprehensive audit trails support fraud investigations, compliance reviews, and anomaly detection. This makes it much harder for fraud to go unnoticed.

7. Granular Data Scoping

Open banking enables scoped data access, so users only share what is necessary, such as transaction history or balances. This reduces data overexposure and associated risk.

8. Fewer Intermediaries Mean a Smaller Attack Surface

Legacy financial integrations often involve third-party aggregators or data brokers. Open banking removes these middle layers, reducing the number of systems that handle sensitive data and cutting down on potential fraud vectors.

9. Behavioural Analysis for Identity Verification

Access to real-time financial data allows fintechs to verify identities using behavioural patterns and spending data, not just static credentials. This reduces the risk of identity fraud and synthetic accounts.

10. Compliance Embedded by Design

Open banking ecosystems align closely with strict regulatory standards. These include the CDR in Australia, GDPR in Europe, and Section 1033 in the US. Security is not bolted on after the fact. It is built into the structure through accreditation, liability frameworks, and consumer protections.

A Safer Financial Ecosystem, by Design

Open banking is not a silver bullet. But it is a major step forward. Instead of relying on brittle, legacy security layers, open banking builds in security, transparency, and user control from the start.

For financial services providers, this is a moment of opportunity:

• Build better fraud detection tools with high-quality, real-time data
• Retire risky practices such as screen scraping
• Reassure your customers that their financial data is safer than ever

Final Thought: Trust Is a Feature

At Fiskil, we believe trust should be built into every interaction. Our managed infrastructure enables banks and fintechs to tap into open banking securely and at scale, while staying aligned with fast-changing regulatory standards.

Because trust is not just a nice-to-have. It is the foundation for everything that comes next.
