AT RISK
US company, no Chinese jurisdiction concerns. But Comcast suffered a 36-million-user data breach in 2023, and this gateway broadcasts a public Wi-Fi hotspot from your home by default. Your ISP controls the firmware.
- Comcast data breach - 36 million customers: Hackers stole credentials for 36 million Comcast customers including usernames, hashed passwords, and partial Social Security numbers. Your gateway account credentials may have been exposed. If you haven't changed your password since late 2023, do it now.
- Public xfinitywifi hotspot - enabled by default: Your gateway broadcasts a second public Wi-Fi network for other Comcast customers by default. Security experts broadly recommend disabling this.
- ISP controls your firmware: Comcast can push firmware updates and remote configurations to your gateway. You cannot fully control the security settings.
- Limited user security configuration: The xFi Gateway doesn't allow advanced security features like custom firewall rules, built-in VPN, or device-level isolation.
