Global Knowledge is an enterprise IT training provider offering scheduled, instructor-led CISSP courses worldwide, generally aimed at organizations investing in staff certification. Individual candidates can enroll, but the format and pricing reflect an enterprise training model rather than a self-paced consumer product.
That enterprise orientation shows up most clearly in pricing and scheduling: seats are typically sold per session at rates set for corporate training budgets, and available dates depend on where and when a given course is running rather than being available on demand. It's a solid option if a company is sponsoring the certification, but a harder one to justify for a candidate paying out of pocket and studying around a day job.
Global Knowledge's scheduled format is built to deliver consistent training across many attendees and locations, which is a different design goal from tracking any one learner's actual readiness to sit the exam. There's no equivalent to a continuously updated pass-likelihood score in that model — progress is generally measured by attendance and course completion rather than a live estimate of exam readiness, which is the specific gap the Readiness Score is designed to close.
