Summit Partners

Summit has a long history of partnering with innovative cybersecurity leaders focused on protecting against both monetary and data breaches in a constantly evolving and ever-expanding threat landscape. We believe the stakes and costs are even higher in Web3, given the decentralized development of and the dollars controlled by Web3 applications.

In a very short time, Halborn has established itself as a globally recognized brand in blockchain security working across Web3 and Web2 environments. The Halborn team has earned a reputation for tackling complex projects and has an impressive record of identifying high-profile vulnerabilities and breaches.
