Cybersecurity has been huge in 2025. While overshadowed by AI funding, there have still been some large cybersecurity exits and acquisitions, most notably Google’s $32 billion acquisition of Wiz. We want to explore the rest of the space, but not just anecdotally. We needed some data.
So, we put our heads together and refined metrics on cybersecurity companies that have received lots of funding and are funded in the Silicon Valley ecosystem. This allows more clear comparisons with similar funding and business models. It also applies the power laws to funding and company concentration in this space.
