Cequence Solutions for Financial Services Organizations

Financial services organizations run on applications, APIs, and data. Digital banking platforms, mobile apps, payment systems, trading portals, partner integrations, and open banking initiatives all rely on interconnected APIs to move money and data in real time. For financial services organizations, this reality makes it clear that protecting the enterprise means protecting the applications and APIs that power revenue, customer trust, and regulatory compliance.

The Role of APIs in Financial Services

APIs are not just integration tools in financial services. They are the backbone of modern banking and financial operations. They enable:

Mobile and online banking experiences
Real-time payments and funds transfers
Open banking and third-party integrations
Credit decisioning and underwriting workflows
Wealth management platforms
Fraud detection and analytics systems

In open banking ecosystems, APIs expose financial data to aggregators, fintech partners, and ecosystem participants. PSD2 and similar regulations require banks to provide API access to third parties. That access enables innovation, but it also introduces new risk.

If an API is compromised, the result is not just downtime. It can mean direct financial loss, large-scale data exposure, regulatory penalties, and reputational damage. For attackers, APIs represent a direct path to high-value assets, and API security solutions become crucial.

The Security Challenges Facing Financial Services Organizations

Financial institutions face a convergence of technical, business, and regulatory pressures that make application and API security uniquely complex.

An Ever-Expanding Attack Surface

Growth in financial services is both organic and inorganic. Institutions are frequently:

Launching new digital products
Modernizing legacy systems
Migrating to hybrid and multi-cloud environments
Acquiring or merging with other institutions
Integrating fintech partners and third-party services

Each initiative introduces new APIs, new integrations, and new potential vulnerabilities. Over time, institutions accumulate shadow APIs, deprecated endpoints, and poorly documented exposed services. Traditional perimeter security does not account for this dynamic sprawl. Without comprehensive API discovery and continuous monitoring, security teams lack visibility into what is actually accessible to the internet.

A Growing Partner Ecosystem

Open banking, embedded finance, and financial aggregators have fundamentally changed how financial institutions share data. Third parties may include financial data aggregators, payment processors, credit bureaus, identity verification providers, and more. Each partner relies on API access. Each integration increases the number of entities interacting with core systems. If APIs are misconfigured or if business logic can be abused, attackers can exploit those same integration pathways.

High-Value Targets for Sophisticated Adversaries

Financial institutions are among the most attractive targets in the threat landscape. They hold direct access to funds, detailed personal and financial information, payment credentials, and more. The potential payoff is significant. As a result, adversaries are sophisticated, persistent, and well-funded.

Common attack types include::

Account takeover through credential stuffing and bot-driven automation
Sensitive data exposure through API misconfigurations
Credit card attacks including stuffing and cloning
Business logic abuse targeting loan applications, promotional offers, or payment flows

These attacks often bypass traditional security controls because they use valid credentials, legitimate API calls, and carefully crafted automation that mimics human behavior. Organizations need bot management and API security solutions that can counter these sophisticated attacks.

Complex and Evolving Regulatory Requirements

Financial services organizations operate in one of the most heavily regulated environments in the world. Security leaders must demonstrate not only that controls exist, but that they are effective and continuously monitored. Key regulatory and standards frameworks include:

Payment Services Directive, PSD2 (EU)
Digital Operational Resilience Act, DORA (EU)
CFPB rules and the Personal Financial Data Rights Rule
Gramm-Leach-Bliley Act, GLBA
FFIEC guidance
NIST 800-204
PCI DSS

Penalties for non-compliance can be severe. Beyond fines, institutions risk supervisory actions, mandated remediation, and long-term reputational harm. Regulators increasingly expect institutions to understand their API inventory, control third-party access, monitor anomalous behavior, and prevent data leakage. Visibility and auditability are essential.

Enabling Agentic AI in Financial Services

Financial services organizations are actively exploring agentic AI to improve operations and customer engagement.

Improve internal productivity by automating workflows
Reduce customer support costs through intelligent self-service
Enhance customer experiences with real-time, personalized interactions
Streamline fraud investigation and compliance analysis

Despite the promise, many CISOs remain cautious. Common concerns include:

Limited visibility into how AI agents interact with APIs
Risk of unauthorized data access or excessive data exposure
Abuse of AI interfaces by automated attackers
Prompt injection or indirect API misuse
Inadequate controls around third-party AI integrations

AI systems ultimately act through APIs. If those APIs are not protected, monitored, and governed, agentic AI can introduce new attack vectors. Security leaders need to ensure that AI-driven interactions are subject to the same rigorous controls as any other digital channel. The leading option for this is a secure AI gateway that gives organizations visibility, control, and governance.

How Cequence Protects Financial Services Organizations

Cequence offers an integrated platform of products that address the specific threats facing financial institutions while enabling innovation:

API Security for API security posture management, testing, and remediation
Bot Management for advanced bot protection, mitigation, and fraud prevention
AI Gateway for secure agentic AI enablement
WAAP for integrated bot management, API security, WAF, and DDoS protection

Comprehensive API Discovery and Visibility

You cannot protect what you cannot see. Cequence API Security automatically discovers and inventories all internal, external, and third-party APIs. This includes undocumented and shadow APIs. Security teams gain a regularly updated view of their API footprint, enabling risk-based prioritization and remediation.

Real-Time Protection Against Account Takeover and Fraud

Cequence Bot Management detects and blocks automated and human-driven attacks targeting authentication and business workflows:

Advanced bot detection that identifies credential stuffing and automation
Behavioral analysis to distinguish legitimate users from malicious actors
Protection against account takeover and API-based fraud
Defense against business logic abuse

Unlike traditional controls that focus on signatures or static rules, Cequence analyzes behavior across sessions, identities, and endpoints. This enables detection of sophisticated, low-and-slow attacks that evade legacy tools. Financial services customers have successfully stopped millions of account takeover attempts using Cequence, preventing direct financial loss and customer harm.

Protection Against Sensitive Data Exposure

APIs frequently expose structured financial and personal data. Misconfigurations, overly permissive responses, or improper authorization can lead to large-scale data leaks. Cequence:

Autonomously Identifies APIs that handle sensitive data
Monitors API responses for excessive data disclosure
Automatically masks sensitive data (configurable)

Secure Enablement of Agentic AI

Cequence enables financial institutions to adopt agentic AI safely through its secure AI Gateway. The AI Gateway makes it easy for organizations to enable agentic AI access to their applications and data without losing control. The AI Gateway includes:

Security controls built in from the start
Monitoring and visibility of users, tools, and calls
Rate limits and behavioral controls
Built-in, configurable guardrails

By treating AI agents as another consumer of applications and data, Cequence ensures consistent policy enforcement across human and machine actors. This approach allows organizations to innovate with AI while maintaining strong guardrails around data access and transaction integrity.
