More About CSI
Computer Services, Inc. (CSI) provides integrated technology platforms and services to banks, credit unions, and other financial services organizations, with a focus on outsourced and hosted delivery models that support core banking operations, customer-facing channels, and regulatory compliance. Its offerings are typically deployed as long-term, managed solutions that interface with existing institution systems through standard integration methods and service-based architectures.
CSI’s core banking solutions (core banking) support deposit, loan, and general ledger processing, along with ancillary functions such as document management, item processing, and reporting. These systems are generally delivered via hosted or cloud-based environments in CSI-operated data centers, using secure network connectivity and interfaces to third-party applications through APIs, batch file exchanges, or message-based middleware. The core platforms are used as the System of Record (SOR) for customer accounts and transactions, and they integrate with digital channels, card networks, and back-office tools.
In digital banking (digital banking), CSI offers online and mobile banking applications for retail and business customers, including features such as account access, funds transfers, bill payment, remote deposit capture, and basic cash management tools. These applications typically leverage responsive web technologies and native mobile apps, connecting to the core systems through secure APIs and adhering to security controls such as multi-factor authentication, encryption in transit, and device-level checks. For business banking clients, CSI extends these capabilities with modules for ACH origination, wire transfers, and administrative controls over user entitlements.
CSI’s payments services (payments processing) encompass debit and credit card processing, Asynchronous Transfer Mode (ATM) driving, and electronic funds transfer, frequently integrating with major card networks and payment rails. The company also provides network connectivity, transaction routing, authorization, and settlement services. These capabilities are positioned for institutions that prefer to outsource card management infrastructure while maintaining control over product design, cardholder experience, and risk parameters.
In regulatory compliance and risk management (regtech), CSI delivers tools for Bank Secrecy Act (BSA) and anti-money laundering (AML) monitoring, fraud detection, and reporting. These solutions typically include rules-based alerting, case management workflows, and standard regulatory report formats, helping institutions align with federal and state banking requirements. They are commonly integrated with core transaction data and third-party sources to support AML scenarios, sanctions screening, customer due diligence, and suspicious activity reporting.
CSI also operates managed services (managed IT services) that include hosted infrastructure for its banking platforms, network services, security monitoring, and cybersecurity offerings. These services are built around secure data centers, layered security controls, and frameworks aligned with banking regulatory expectations for vendor management, business continuity, and information security. Enterprise clients use CSI’s managed services to reduce on-premises (on-prem) infrastructure while maintaining compliance, auditability, and service levels appropriate for regulated financial environments.
In an enterprise technology directory, CSI can be classified primarily under core banking systems, digital banking platforms, payments processing services, regtech and compliance solutions, and managed IT and security services for financial institutions.
