Overview

Bitdefender was founded in 2001, headquartered in Bucharest, Romania, and is one of the world's top cyber security companies. Bitdefender consistently tops AV-Test, AV-Comparatives, and SE Labs independent evaluations in the consumer anti-virus space, while its GravityZone platform delivers EDR/XDR, endpoint protection, email security, and MDR managed detection and response for enterprises.

Bitdefender's technology is used by over 500 million users across 140+ countries, and its threat detection engine is also licensed to other security vendors. The Bitdefender Threat Network collects global threat data in real time, feeding the latest attack signatures and anomaly behavior models to the detection engine.
