Trend Micro: the history behind cybersecurity
Trend Micro was founded in 1988 by Steve Chang, Jenny Chang and Eva Chen and built its early business around antivirus software.
How Trend Micro developed
The company expanded globally as personal computers and corporate networks became common, then moved beyond desktop antivirus into email, server, cloud, network and endpoint security. It listed in Tokyo in 1998 and remained headquartered in Japan while operating internationally.
Trend Micro in 2026
By 2026, Trend Micro provided cybersecurity products spanning endpoint, cloud, network and extended detection and response.
Its long history shows how security vendors have had to reinvent themselves repeatedly as threats moved from infected disks to email, web traffic, cloud workloads and identity-driven attacks.
