Security Verdict
Vantiva is a publicly listed French company, formerly Technicolor, that makes ISP gateways such as Comcast's Xfinity XB7. Since January 2024 it also owns CommScope's Home Networks business, including the ARRIS SURFboard modem line, and CommScope received a 25% stake. Its devices are built by contract manufacturers in Asia and Latin America. Recent vulnerabilities are mostly in older Technicolor models, and none are on CISA's exploited list.
Bottom line: Vantiva gateways have no actively exploited flaws on record. Most are ISP equipment, so your ISP controls when they are updated.
