This is the expiration date of the subscription for Web Filtering updates. This is a date an admin must track proactively, since Check Point stops delivering new category-database updates once this subscription lapses, meaning the blade keeps running and blocking based on an increasingly outdated category list without any obvious outward sign that updates have stopped. For example, a license expiring in three weeks with no renewal underway means URL categorization accuracy will start silently degrading right after that date.
