Global cybersecurity funding Q3

Highlights

Global cybersecurity funding hits $6.8 billion in Q3 2023, driven by larger round sizes with overall deal counts declining sequentially.
AI-oriented and identity security startups dominate fundraising, with at least 18 firms closing $100 million-plus rounds and Keyfactor raising a $1 billion round in July.
Visa leads sector M&A with a $2.4 billion acquisition of BioCatch, while Cyera acquires Oasis Security for about $1 billion, reflecting aggressive industry consolidation.

AI and identity security drive quarterly funding

As reported by Crunchbase News, the rise in third-quarter cybersecurity funding comes from bigger deal sizes rather than a broader increase in activity. Crunchbase data shows round counts decline sequentially across all stages even as total capital reaches $6.8 billion.

AI-focused companies account for most of the quarter's funding, with identity security drawing particular attention from investors. At least 18 companies operating at the intersection of artificial intelligence and cybersecurity close rounds of $100 million or more during the quarter.

Keyfactor, an enterprise identity security provider based in Ohio, brings in the largest round with $1 billion in July led by Summit Partners. Island, based in Dallas, matches the second-largest fundraising total with a $400 million Series F in September led by Evolution Equity Partners, while Cyera announces a separate $400 million investment led by Goldman Sachs Growth Equity just three months after raising $600 million.

Acquisitions add momentum across the sector

The quarter also includes sizable acquisitions, even as the IPO market remains sluggish. Visa posts the largest transaction with its $2.4 billion August purchase of anti-fraud technology provider BioCatch, a move tied to its broader push to strengthen fraud detection and prevention for the AI era.

Cyera also shows how well-capitalized private cybersecurity companies are putting money to work, acquiring Oasis Security in a deal reportedly valued at around $1 billion. The combination of larger venture rounds and strategic M&A points to a supportive backdrop for cybersecurity businesses as concerns over risks linked to rapidly advancing AI continue to shape spending priorities.

In our earlier coverage of AI mega-rounds reshaping venture funding, we noted that larger AI deals were taking a growing share of capital even as overall deal counts fell. We explained how this dynamic is pushing investors to write bigger cheques for fewer companies, increasing concentration risk and intensifying competition as heavyweight backers crowd into the largest rounds.
