Broadcom

Broadcom is a US multinational semiconductor and infrastructure software company headquartered in San Jose, California. It produces networking chips, storage controllers, and enterprise software, with Major customers across data centre, telecommunications, and enterprise IT sectors. Broadcom became one of five companies added to Anthropic's Project Glasswing partner list in April 2026, alongside CrowdStrike, Nvidia, Palo Alto Networks and Cisco, expanding the programme from its original twelve founding partners.

Project Glasswing gives partners pre-deployment access to Claude Mythos Preview and involves commitments to responsible deployment and coordinated vulnerability disclosure. Broadcom's inclusion reflects its role at the infrastructure layer: Mythos's 20-hour autonomous attack-chain capability, confirmed by the UK AI Security Institute on 15 April, runs on networking and storage infrastructure Broadcom supplies.

Broadcom's addition to Glasswing coincided with the 7 April publication of Anthropic's 244-page Alignment Risk Update, which noted that over 99% of the vulnerabilities Mythos discovered remain unpatched, with coordinated disclosure still in progress. As an infrastructure vendor with deep integration into the enterprise stack, Broadcom's involvement in managing the disclosure pipeline is commercially significant: Mythos-discovered vulnerabilities in Broadcom's networking products would affect most Fortune 500 data centre environments.
