Solana Foundation appoints former Twitter security chief Michael Coates as CISO

Michael Coates has joined the Solana Foundation as its Chief Information Security Officer after a career spanning leadership roles at Mozilla, Twitter and enterprise security startup Altitude Networks.

According to a post shared by Michael Coates on X, he has taken over as CISO of the Solana Foundation, where he will lead security efforts across the network as blockchain adoption and institutional activity continue to grow.

Coates cites Solana’s scale as a key factor

Explaining his decision, Coates said Solana now handles tens of billions of dollars in daily stablecoin volume while processing more transactions each day than most of the cryptocurrency industry combined. He also pointed to recent tokenization activity on the network, including the launch of SpaceX tokenized shares on the same day the asset debuted on Nasdaq.

Coates enters the role after serving as Head of Security at Mozilla during the browser competition era and becoming Twitter’s first Chief Information Security Officer as the social media platform expanded globally. He later founded enterprise SaaS security company Altitude Networks, which entered the crypto sector after its acquisition by CoinList.

Within the Solana Foundation, Coates said his work will include strengthening operational security, improving application security practices and addressing risks unique to digital assets. He added that he also plans to work with policymakers and standards bodies on cybersecurity regulation affecting the crypto industry.

Describing the current threat environment, Coates said attackers remain heavily motivated to steal digital assets and noted that malicious uses of artificial intelligence are becoming an increasing security concern. He added that AI can also strengthen defensive capabilities when used effectively and referenced his congressional testimony on the subject earlier this year.

The appointment comes as digital asset firms continue bringing experienced leaders from technology, cybersecurity and regulatory backgrounds into senior positions while institutional participation expands across the sector.

A similar trend emerged last year when former U.S. Commodity Futures Trading Commission Chairman Christopher Giancarlo joined Swiss digital asset bank Sygnum as a senior policy advisor. Sygnum said at the time that Giancarlo would advise on global regulation, strategic partnerships and international growth, underscoring the industry’s continued recruitment of experienced executives as crypto infrastructure develops.
