Program Overview

At Comcast, we’re committed to working alongside the security research community, and know we’re at our best when we continually enhance this process. That's why we’ve formally launched Xfinity Home’s bug bounty program, as a way to reward contributions from security researchers who help make Xfinity Home more secure.

Xfinity Home is a complete home security system, with 24/7 professional monitoring, and battery/cellular backup. Our customers enjoy peace of mind through live video monitoring with our Xfinity cameras, and motion activated recording that detects people, vehicles, and pets. The door/window sensors allow you to monitor your home and receive real-time alerts when doors are open or closed.

Please note, this program is specifically scoped for Xfinity Home. If you believe you've found a security issue related to any other product or service please report through our vulnerability reporting page.


For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, in some cases, a vulnerability priority will be modified due to its attack complexity, requirements, likelihood, or impact of successful exploitation.

All submissions are reviewed to determine an accurate priority and any change will result in a detailed explanation provided to the researcher with the opportunity for a follow up.

Reward Guidelines:

Rewards are determined through an internal impact assessment, researcher interaction and the overall quality, content, and accuracy of the report.

High impact findings:

Comcast may reward eligible P1 submissions up to $10,000 for findings related to:

  1. Remote unauthorized access (via publicly accessible internet, not on the same LAN/wireless network) of:

    • Cloud storage videos
    • Live camera feeds
  2. Bypassing Armed Systems

  3. Abuse/Theft of Service
