Connected Banking Is Reshaping Third-Party Risk Management in Financial Services
Connected banking is expanding financial ecosystems beyond traditional banking environments. This blog explores how APIs, fintech partnerships, cloud platforms, and embedded finance are changing third-party risk management by creating new security, operational, and regulatory challenges.
Definition: Connected Banking and Third-Party Risk Management
Connected banking refers to the growing ecosystem of financial services delivered through APIs, cloud platforms, fintech partnerships, embedded finance solutions, and real-time integrations between banks and external providers.
While this model creates new opportunities for innovation and customer experience, it also changes the way financial institutions must approach third-party risk management.
Banks are no longer operating within a closed technology environment.
They are becoming part of interconnected ecosystems where fintech companies, software providers, cloud platforms, payment processors, and technology partners all play a role in delivering financial services.
As these relationships expand, third-party risk management is becoming less of a compliance function and more of a strategic capability required to maintain security, resilience, and customer trust.
The Growth of Connected Banking Is Expanding the Risk Landscape
Traditional banking was built around controlled environments with clearly defined technology boundaries.
Connected banking operates differently.
Financial institutions now rely on external providers for everything from payment processing and customer authentication to lending platforms, data analytics, treasury management, and embedded financial services.
Each integration creates value, but each connection also introduces new risk.
A third-party provider may have access to sensitive customer information, critical systems, or operational processes that directly impact the bank and its customers.
The result is a broader digital supply chain where a security failure at one provider can create consequences across multiple organizations.
The question is no longer simply: "Is our bank secure?"
The more important question is: "Can we understand and manage the risk introduced by every organization connected to our ecosystem?"
Why Connected Banking Creates New Third-Party Risk Challenges
The expansion of connected banking introduces several challenges that traditional vendor risk management processes were not designed to handle.
Every API connection, integration, and external platform creates another potential pathway for attackers.
Modern attackers increasingly target trusted relationships because compromising one provider may provide access to multiple downstream organizations.
A single weak connection can create exposure far beyond the original vendor.
Increased Data Sharing
Connected banking depends on the movement of information between organizations.
Customer data, financial information, transaction details, and operational data may flow between banks and multiple external providers.
This creates additional privacy, security, and regulatory considerations that require continuous oversight.
Operational Dependency
Many financial institutions now rely on third parties to deliver critical services.
Payment providers, cloud platforms, identity services, and fintech partners can become essential components of daily operations.
If one provider experiences disruption, the impact can extend directly to customers.
Fourth-Party and Supply Chain Risk
A financial institution may have strong visibility into its direct vendors but limited visibility into the suppliers those vendors rely on.
A fintech partner may depend on multiple cloud providers, software vendors, and infrastructure services.
This creates layers of dependency that traditional vendor inventories often fail to capture.
Regulatory Expectations Are Changing
Regulators are increasingly focused on how financial institutions manage technology dependencies.
Frameworks such as the Digital Operational Resilience Act (DORA) emphasize the importance of managing ICT third-party risk throughout the entire lifecycle of a relationship.
The expectation is moving beyond simply reviewing vendors during onboarding.
Organizations must understand:
- How critical a provider is to operations.
- What systems and data they can access.
- How risks change over time.
- What happens if the relationship needs to end.
- How quickly the organization can respond if a supplier is compromised.
Connected banking makes these requirements more difficult to achieve when third-party risk processes rely heavily on manual reviews and disconnected systems.
Why Traditional TPRM Struggles in a Connected Banking Environment
Many organizations still manage third-party risk through annual questionnaires, spreadsheets, and manual approval workflows.
These methods can provide useful information, but they struggle when vendor ecosystems become larger and more complex.
A vendor may complete a security assessment during onboarding, but the risk profile can change significantly afterward.
The vendor may introduce new technologies, add subprocessors, expand permissions, change ownership, experience vulnerabilities, or introduce new services.
Without continuous visibility, organizations are often managing yesterday's risk instead of today's exposure.
The challenge is not collecting more information.
The challenge is maintaining an accurate understanding of risk as relationships evolve.
What Modern Third-Party Risk Management Requires
Connected banking requires a more dynamic approach to vendor risk.
Modern programs need to combine automation, continuous monitoring, and risk-based decision making across the entire vendor lifecycle.
This includes understanding vendor risk before onboarding, automatically adjusting assessment requirements based on risk, monitoring changes throughout the relationship, and ensuring secure offboarding when a relationship ends.
The goal is not to slow down innovation, it is to allow financial institutions to safely adopt new partnerships while maintaining control over the risks those partnerships create.
How TPSaaS Helps Financial Institutions Manage Connected Banking Risk
TPSaaS was designed for organizations managing increasingly complex third-party ecosystems.
Rather than relying on fragmented spreadsheets and disconnected processes, TPSaaS creates a centralized view across the vendor lifecycle, connecting procurement, cybersecurity, compliance, and governance teams.
The platform supports financial institutions by helping automate vendor onboarding, apply risk-based assessments, continuously monitor vendor security posture, track remediation activities, and maintain audit-ready evidence throughout the relationship.
By creating a single source of truth for third-party security, organizations gain clearer visibility into their supplier ecosystem and can make faster, more informed risk decisions.
The Future of Banking Requires Better Third-Party Visibility
Connected banking is not slowing down.
Financial institutions will continue adopting APIs, fintech partnerships, embedded finance solutions, and cloud-based services to improve customer experiences and operational efficiency.
The organizations that succeed will be those that can balance innovation with strong third-party risk management.
Traditional vendor management approaches were built for a world of fewer connections and slower change.
Modern financial ecosystems require continuous visibility, automated workflows, and risk-based decision making.
Third-party risk management is no longer about reviewing vendors once a year.
It is about understanding the ecosystem that keeps the business running every day.
Frequently Asked Questions
What is connected banking?
Connected banking is a model where financial institutions integrate with fintech companies, customers, platforms, and technology providers through APIs, cloud services, and real-time data exchange.
How does connected banking increase third-party risk?
Connected banking increases third-party risk by expanding the number of external relationships that access sensitive data, support critical services, and connect to financial systems.
Why is DORA important for connected banking?
DORA emphasizes lifecycle management of ICT third-party risk, including due diligence, monitoring, concentration risk management, and exit planning.
Why are traditional vendor assessments not enough for connected banking?
Traditional assessments provide a point-in-time view of risk, while connected banking environments change constantly through new integrations, technologies, and vendor dependencies.
