Start by identifying the software your business uses and checking the developer's official website for its support lifecycle and end-of-life dates. Pay particular attention to applications that handle sensitive information, connect to the internet or are essential to your daily operations.
It's also worth reviewing older software that employees may still rely on, even if it isn't part of your main IT setup. Keeping an up-to-date software inventory can help you identify applications that need replacing before they become a problem.
