96% of Fintech Firms Hit as API and Identity Risks Surge

A Sector Built on Connections — and Exposed by Them

Fintech's rise has been defined by seamless connectivity: instant payments, embedded lending, and AI-driven investment tools that link banks, apps, and third-party services in real time. That same interconnectedness, however, is now emerging as the industry's biggest liability. Recent reporting highlights a striking statistic — roughly 96% of fintech firms have experienced some form of attack tied to their application programming interfaces (APIs), underscoring how deeply exposed the sector has become as it scales 1.

The Rise of Non-Human Identities

At the center of this vulnerability is a category of digital actors most consumers never think about: non-human identities, such as API keys, service accounts, and automated bots that vastly outnumber human employees at fintech companies 12. Every transaction, transfer, or account sync generates machine-to-machine communication, and each of those connections represents a potential entry point for attackers. Coverage describing this as a "silent killer" argues that the sheer volume of these credentials — often under-monitored and loosely governed — makes traditional security models built around human user access increasingly obsolete 2. As fintech platforms multiply integrations with banks, payment processors, and data providers, the attack surface expands correspondingly, and breaches involving compromised keys or tokens can cascade across multiple institutions at once.

AI Adds a New Layer of Complexity

Security is not the only area where fintech's technical foundations are being stress-tested. As artificial intelligence models move from pilot projects into full production, industry leaders are shifting focus away from raw model performance toward broader concerns: reliability, governance, cost control, and how these systems actually perform under real enterprise conditions 3. This mirrors the API security conversation in a key way — both reflect a maturing industry grappling with the operational and trust implications of technology that was adopted quickly, sometimes faster than governance frameworks could keep pace.

That AI momentum is also visible in fresh product activity. Agentic AI offerings — autonomous systems capable of executing tasks with limited human oversight — dominated a recent wave of fintech product launches and partnerships, including announcements from TransFi, OSL Group, and Ionic 6. These agentic tools promise efficiency gains but also introduce new identity and access questions similar to those raised by API-related vulnerabilities, since autonomous agents themselves function as another form of non-human actor requiring credentials and permissions.

Capital Keeps Flowing Despite the Risk

Even as security concerns mount, investment and competitive activity in fintech show no signs of slowing. Weekly deal roundups continue to track fresh funding and transactions across the sector 4, while venture-backed entrants like Corgi Invest are attempting to disrupt established asset managers such as BlackRock by using AI to launch a broad slate of low-fee ETFs, intensifying competition in fund pricing 5.

Why It Matters

Taken together, the coverage paints a picture of an industry expanding on two fronts simultaneously — deeper AI integration and broader API-driven connectivity — without security infrastructure fully catching up. For fintech firms, regulators, and the consumers who trust them with financial data, the message across these reports is consistent: innovation and exposure are advancing at the same pace, and closing that gap is becoming an urgent priority rather than a future concern.
