About the vendor

What is Viettel Threat Intelligence?

Viettel Threat Intelligence is operated by Viettel Cybersecurity, the security division of Viettel Group. Vietnam's largest telecommunications company and a major telecoms operator across Southeast Asia. Their threat intelligence covers malware, phishing, and attack infrastructure relevant to Vietnamese and regional users. Viettel's network reach means their threat intelligence is embedded in ISP-level filtering across Vietnam and other markets where Viettel operates.

Because Viettel is Vietnam's largest telecom, their threat intelligence can be applied at the carrier level across millions of Vietnamese subscribers. A listing can mean ISP-level blocking for all Viettel users, affecting access to your domain for a significant portion of Vietnam's internet users.
