Securing Digital Identities in Financial Services – The New Strategic Imperative

In today’s digital-first economy, the financial services industry sits at the intersection of convenience, trust, and risk. The rapid acceleration of digital transformation has unlocked new opportunities for personalized services, frictionless experiences, and global connectivity. However, this shift has also broadened the attack surface for cybercriminals, placing digital identities at the center of a growing crisis. Fraud, identity theft, unauthorized access, and advanced AI-driven deepfake attacks have created significant vulnerabilities that financial service providers cannot ignore.

For financial institutions, protecting digital identities is no longer just a cyber-security problem – it’s a strategic imperative. Secure and converged identity and access management (IAM) is critical to safeguarding customer trust, meeting evolving regulatory requirements, and preventing financial and reputational losses. A single breach can cost millions and irreparably damage trust. In fact, 80%¹ of financial service organizations have experienced data breaches due to weak authentication, with each incident costing an average of $2 million.²

This blog will explore the threats to digital identities in financial services and outline the key strategies financial service providers can adopt to protect customer, workforce, and B2B identities.

Financial institutions have become prime targets for cybercriminals, and their methods have grown increasingly sophisticated. Digital identities—including those representing customers, workers, and third-party vendors/partners/providers (B2B, herein)—are now at the forefront of these attacks. The key attack vectors threatening these identities in the financial services industry include:

1. Customer Identity Attacks:

Account Takeover (ATO) fraud has surged by 354%³ in the past year, as attackers exploit weak passwords, phishing campaigns, and stolen credentials to access customer accounts. Social engineering tactics, such as authorized push payment (APP) fraud, trick legitimate users into transferring large sums of money to fraudulent accounts. The growing reliance on digital banking services has exacerbated this problem, as customers often reuse weak or breached credentials across multiple platforms. Meanwhile, advancements in generative AI enable fraudsters to create realistic phishing emails, cloned voices, and deepfakes, making it even harder for customers to discern legitimate interactions from fraudulent ones.

2. Workforce Identity Breaches:

A recent incident in Hong Kong revealed how advanced deepfake technology was used to deceive an employee into authorizing a $25 million transaction during a video call. Fraudsters replicated the CFO’s face and voice so convincingly that the employee believed they were engaging with real colleagues. This incident underscores the devastating potential of deepfakes to manipulate workforce identities, bypass traditional verification methods, and exploit trust at critical decision points. In the financial services industry, this issue is further compounded by an ever-growing entitlements explosion, where employees accumulate excessive permissions over time, often far beyond what is necessary for their roles, resulting in overprovisioned access.

3. B2B Identity Exploitation:

Third-party vendors, partners, and providers access financial systems, data, and resources whether providing services at the back- or front-end of the customer experience. Weak controls in B2B access management and end-to-end identity governance increase risks of unauthorized access, supply chain attacks, and compromised credentials. High-profile incidents, like the 2020 SolarWinds breach, demonstrate how fragmented access policies can leave financial ecosystems exposed. In that case, attackers infiltrated the supply chain to compromise thousands of organizations, including major financial institutions, highlighting the urgent need for modernized identity governance and continuous threat monitoring.

Customers are the lifeblood of the financial industry, and protecting their digital identities must be a top priority. Financial service providers, particularly progressive retail banks, continue to increase their investments in Customer Identity and Access Management (CIAM) to deliver seamless, secure user experiences while addressing growing fraud risks.

These five key capabilities are critical in securing customer identities in the financial services industry:

1. Threat Detection and Response:

Continuous monitoring and real-time analytics identify anomalies in user behavior. For example, a sudden high-value transfer from an unusual location triggers alerts or step-up authentication. With fraud tactics becoming more sophisticated, real-time detection powered by AI and machine learning can recognize unusual behavior patterns before a transaction is completed. Financial service providers can also integrate risk signals from third-party fraud detection tools to detect and block unauthorized activity across all channels of customer interaction.

2. Dynamic Multi-Factor Authentication (MFA)

By using adaptive risk-based policies, financial institutions can require additional verification (e.g., biometric, OTP) only when suspicious activity is detected, ensuring a balance between security and user convenience. This approach avoids adding friction for trusted users while delivering stronger protection for high-risk transactions, such as wire transfers or password resets. For example, step-up authentication can be triggered dynamically if a customer logs in from a previously unseen location, further protecting against account takeover attempts.

3. Identity Verification

Advanced liveness detection and biometric matching verify users against trusted data sources, ensuring that fraudsters cannot exploit stolen or synthetic identities. These capabilities significantly reduce the risk of new account fraud, which often involves fabricated or compromised credentials. For instance, facial recognition solutions can analyze micro-expressions and movement patterns to verify that a live person is presenting a legitimate identity document, preventing fraudulent attempts to manipulate the verification process.

4. Dynamic Authorization

Policy-based access controls allow financial service providers to grant (or deny access) in real time based on contextual signals, such as location, device, or transaction type. This prevents unauthorized account access even if credentials are compromised. Financial institutions can use dynamic authorization to enforce step-up verification for high-value transactions or limit functionality when a risk signal is detected, such as during off-hours or from unrecognized devices. These controls ensure that access policies adapt dynamically to evolving threats without compromising user experience.

5. Verified Credentials

Cryptographically secure digital credentials bind identity data to users, reducing reliance on physical documents and minimizing opportunities for fraud. Verified credentials ensure that only authentic users can complete high-value transactions. For example, during customer onboarding, verified credentials can validate identity attributes such as employment or income status, enabling secure and streamlined loan application processes. Additionally, these credentials can be revoked in real time if fraud is detected, offering an extra layer of protection.

Enterprise financial providers face a uniquely complex challenge when managing workforce identities. Operating across multiple geographical, organizational, and jurisdictional boundaries often leads to identity blind spots, where unauthorized access goes unnoticed, and overprovisioned access accumulates over time. This complexity creates significant security vulnerabilities, as attackers can exploit these gaps to move laterally across systems, access sensitive data, or disrupt critical infrastructure.

A robust Workforce Identity and Access Management solution addresses these challenges through automation, real-time risk assessment, and enforcement of Zero Trust security.

These five key capabilities are critical in securing workforce identities in the financial services industry:

1. Threat Detection and Response

Behavioral analytics continuously monitor workforce activities to detect unusual access patterns or suspicious actions, such as logins from unapproved devices or locations. By analyzing workforce behavior in real time, financial service providers can quickly identify anomalies, such as unauthorized access attempts or irregular usage patterns. Integrating threat signals from multiple systems enhances visibility, enabling IT teams to act swiftly and prevent breaches before they escalate.

2. Dynamic Multi-Factor Authentication (MFA)

Adaptive MFA ensures that workers are authenticated securely, using methods like biometrics or one-time passcodes. For high-risk or privileged accounts, financial service providers can enforce additional verification layers, such as liveness detection or device validation. This ensures that attackers cannot exploit stolen workforce credentials to access sensitive systems, particularly in hybrid or remote work environments.

3. Identity Verification

Robust verification processes confirm the authenticity of workers during onboarding, reducing risks associated with fake identities or impersonation attempts. Advanced identity verification tools, such as biometric checks or digital credentials, ensure that only verified workers can gain access to enterprise systems. Continuous re-verification processes further reduce the risks of long-term access misuse or unauthorized privilege escalations.

4. Dynamic Authorization

Fine-grained access controls enforce policies that restrict access based on roles, devices, and risk signals. For example, privileged accounts can be gated with additional verification steps. This capability allows financial service providers to enforce the principle of least privilege, ensuring that workers only access the data and systems necessary for their roles. By integrating real-time risk signals, dynamic authorization also adapts to changing contexts, such as unusual access times or locations.

5. Identity Governance and Administration (IGA)

Automating access provisioning, de-provisioning, and certifications ensure that workers have the right level of access while reducing manual errors and insider threats. IGA solutions centralize identity lifecycle management, enabling IT teams to manage access across complex organizational hierarchies seamlessly. This automation reduces the risk of overprovisioned access and simplifies compliance with regulatory requirements, such as GDPR or SOX, through detailed reporting and audit trails.

The financial services ecosystem relies heavily on external partners, vendors, and third-party providers (TPPs). Managing these B2B relationships securely is critical to preventing supply chain attacks and unauthorized access. As financial institutions expand their networks to include a growing first- and third-party ecosystem, managing B2B access becomes both essential and increasingly complex. Ecosystem expansion creates opportunities for delivering value-added services to customers (and all that comes with it), but potentially amplifies vulnerabilities at the same time.

A robust B2B Identity and Access Management solution addresses these challenges delivering layered security at scale across the third-party ecosystem.

These five key capabilities are critical in securing B2B identities in the financial services industry:

1. Threat Detection and Response

Continuous monitoring identifies anomalies in third-party access, such as unauthorized attempts to access sensitive systems. Real-time analytics and AI-powered tools provide visibility into vendor behavior, enabling financial service providers to detect unusual patterns, such as repeated failed login attempts or unexpected access from new IP addresses. By acting on these insights, financial institutions can block suspicious activities and mitigate risks before attackers exploit access weaknesses.

2. Dynamic Multi-Factor Authentication (MFA)

Adding adaptive MFA ensures that only verified partners can access critical systems, preventing misuse of stolen credentials. Unlike static MFA, adaptive MFA adjusts based on real-time risk signals, such as unusual login behavior or access requests from high-risk locations. For instance, financial service providers can enforce additional authentication steps when third-party vendors attempt to access privileged systems, reducing the risk of compromised credentials being exploited.

3. Single Sign-On (SSO)

Unified access management simplifies authentication across multiple systems, enhancing user experience and reducing friction for trusted partners. By enabling a single, secure authentication process, SSO eliminates the need for third-party users to manage multiple sets of credentials, reducing password fatigue and improving security. Financial institutions benefit from centralized oversight, ensuring that access policies are consistently enforced across all vendor and partner interactions.

4. Dynamic Authorization

Policy-based controls dynamically manage access privileges based on partner roles, contexts, and risk signals, minimizing the attack surface. These fine-grained access controls ensure that third-party users are granted the minimum level of access required to perform their tasks, aligning with the principle of least privilege. For example, access can be restricted to specific systems or revoked dynamically when risk signals, such as a sudden change in user behavior, are detected.

5. Identity Governance and Administration (IGA)

Automating the onboarding and offboarding of third-party users ensures compliance with internal security policies and regulatory requirements. IGA solutions streamline access provisioning and de-provisioning processes, reducing the risk of overprovisioned or lingering accounts that attackers could exploit. Additionally, automated audit trails and reporting simplify regulatory compliance, helping financial institutions demonstrate robust controls over third-party access.

Fragmented legacy IAM solutions no longer equip financial services providers to detect, respond to, and prevent the rapidly evolving attacks against customer, workforce, and B2B identities. This has spurred many, especially in retail banking, to turbo-charge their IAM modernization, consolidation, and convergence. By no means does this imply that the biggest banks, insurers, and wealth management providers will hand the proverbial keys to one IAM vendor, but it certainly means that the most progressive of these providers are looking to squeeze more value and reduce total cost of ownership (TCO), and most importantly – secure ALL their identities from one control plane.

IAM convergence allows financial service providers to centralize and streamline identity management processes across all user groups, reducing identity silos and ensuring consistent security policies. By unifying customer, workforce, and B2B identity management under a single (or fewer) platform(s), financial institutions can gain full visibility into access behaviors and identity lifecycles, thus providing holistic identity security across their end-to-end ecosystems. This unified approach strengthens security by eliminating gaps that cybercriminals exploit while simplifying operations and lowering administrative overhead. With a modernized IAM infrastructure, financial providers can mitigate risk, enhance trust, and deliver secure, frictionless experiences across every identity touchpoint.
