ISC2 CPE (Continuing Professional Education) credits are a system used to track and measure the ongoing professional development and education of certified members.
To earn these credits on a monthly basis by completing Machines, Challenges, and ProLabs, you must have an active HTB VIP+ or HTB PRO subscription (HTB PRO includes full VIP+ access).
You can learn more about how credits are distributed in our companion article:
Locating Your ISC2 ID
An ISC2 ID, often referred to as your "Member ID" or "Certification ID," is a unique series of numbers assigned to each certified member of ISC2 (for example: 123456). Your ISC2 ID is typically provided to you when you first become certified or join ISC2 as a member. It is used to verify your certification status and participate in ISC2 activities.
Steps to Add Your ISC2 ID to Your Account
To link your Member ID to your HackTheBox account, please follow these exact steps:
Log in to HTB Labs and navigate to your Account Settings.
Click on the Manage HTB Account button. This action will redirect you to your HTB Account user settings.
Locate the ISC2 ID field and enter your unique ID number.
Save your changes to successfully link your accounts.
Please note that CPE credits are only awarded after you have successfully added your ISC2 ID to your account and while you maintain an active HTB VIP+ or HTB PRO subscription.
You will not receive retroactive credits for any platform activities completed before you added your ID or before you started your HTB VIP+ or HTB PRO subscription.
