Enterprise information systems have undergone significant transformations and advancements over time. The management landscape has been reshaped due to corporate mergers, the need for internal controls, and regulatory compliance focused on personal data protection. Additionally, the rise of new businesses has emerged in response to fierce competition, leading to the development of innovative systems aimed at enhancing decision-making processes. Existing systems within established businesses are being refined to boost profitability, yet this has resulted in the creation of various systems that operate in isolation across different departments, each managed separately. This fragmented approach not only escalates the total cost of system maintenance but also hampers the overall efficiency of enterprise management. To address these challenges, enterprise information systems necessitate a system architecture and implementation that are "highly adaptable" and "highly flexible." Service-Oriented Architecture (SOA) has gained attention as a solution to these requirements, with the Enterprise Service Bus (ESB) serving as the integration technology that facilitates a cohesive architecture designed for enhanced reusability. By leveraging these approaches, organizations can streamline their operations and improve cross-departmental collaboration.

Companies that develop security products face a significant demand to create integrations with various third-party applications. This necessity arises from several factors, including customer expectations and the desire to enhance the functionality of their offerings. The target systems for these integrations can exist in diverse environments such as cloud, on-premise, or hybrid setups. The complexity increases due to the wide array of integration options provided by these target systems, including various interfaces like REST API, SOAP, SFTP, Message Queue, and SDKs. Additionally, the different data formats, such as JSON, XML, and Syslog, further complicate matters. Authentication and authorization methods also vary, with options including OAuth, API Tokens, and multi-factor authentication. Furthermore, challenges like rate limits, pagination options, latency issues, concurrency control, and data volume requirements must be addressed. As a result, security product companies frequently resort to developing customized, non-standard connectors for these target systems. This practice not only escalates development and support costs but also results in connectors that may underperform in terms of scalability, efficiency, and adaptability to future needs. Ultimately, the lack of standardization can hinder the overall integration process and impact customer satisfaction negatively.
