Identifying and addressing potential security risks in legacy applications

Having a complete understanding of your application portfolio is vital to combat security-related risks. However, many organizations are working with a limited view, due in part to undocumented and heavily modified legacy applications.

FAQ

What is application rationalization?

Application rationalization is a strategic process used to reduce costs and complexity within an organization’s software portfolio by eliminating “application sprawl”. It involves a structured approach to evaluate the business value and technical fitness of every application in a portfolio. The goal is to determine whether to tolerate, invest, migrate, or retire each application to mitigate security risks and fuel innovation.

Application rationalization and modernization differ in scope and objectives. In short, rationalization acts as the roadmap that identifies which applications are worth keeping and updating, while modernization is the execution of those updates to bring the systems into a modern state.

Within the application rationalization five step framework, the specific decisions to keep, consolidate, retire, replace, or migrate an application are made during the Assess phase. IT teams must analyze each application to determine what its business value and technical fitness are. Based on where it places on these two axes, the decision for how to move these applications forward can be determined.


To support these decisions, the Intellisys platform provides automated documentation artifacts—such as reports on code complexity, dead or redundant code, and database models—to help evaluate an application’s technical fitness. Additionally, AI-infused processes can consolidate logic into rules, allowing organizations to export these findings into project management tools (like Jira) to determine which specific rules to keep, update, or delete.

The cost of not rationalizing an application portfolio includes significant financial, operational, and security burdens. The primary consequences are:

  • Financial Waste: Organizations often find themselves wasting time and money just to “keep the lights on,” maintaining systems that may be redundant or inefficient. In contrast, one case study of a US Telecom company showed that rationalizing and merging systems resulted in an estimated $10 million in savings.
  • Security and Operational Risks: Failing to rationalize leads to a limited view of the software portfolio, especially regarding undocumented or heavily modified legacy applications. This lack of visibility makes it difficult to identify and address security-related risks and broader operational vulnerabilities.
  • Application Sprawl: Without a structured rationalization process, organizations suffer from “application sprawl,” which increases the overall complexity of the IT environment.
  • Stifled Innovation: Resources that could be used to fuel innovation are instead tied up in maintaining an unoptimized portfolio. Rationalization is considered an essential step to free up these resources and properly modernize systems.

To prevent application sprawl from recurring after the initial rationalization process, organizations must transition from a one-time “cleanup” to a continuous management strategy. This includes:

  • Establish On-going Monitoring: Ensures that the portfolio is regularly reviewed rather than allowing undocumented systems to accumulate again over time.
  • Maintain a Central Repository: Creates a single source of truth for all software assets, so IT leaders can maintain a “complete understanding” of the portfolio and avoid the “limited view” that leads to sprawl.
  • Continuous Stakeholder Communication: Keeps leadership aligned and ensures that new applications are only added if they align with business value and technical fitness.
  • Leverage Automated Tools for Visibility: Use platforms like Intellisys to quickly generate current reports on inventory, complexity, and redundant code. With these, teams can identify and deactivate “dead code” or redundant functionalities before they contribute to significant sprawl.
  • Integrate with Project Management: Summarize business rules using AI-enhanced processes and export them into tools like Jira to systematically determine which new rules or functionalities to keep, update, or delete.
