What October told us
October 2025 produced $1.34B in disclosed funding across 41 rounds — up 98% year-over-year — and continued the 2025 M&A consolidation theme with a new buyer archetype taking center stage: private equity going public-to-private on cyber. Francisco Partners' $2.2B take-private of Jamf and Veeam's $1.725B acquisition of Securiti combined for nearly $4B in disclosed M&A value, more than the next four largest M&A months of the year combined excluding Wiz and CyberArk.
The funding picture was more conventional. Chainguard's fifth appearance — a $280M growth round led by General Catalyst at a reported $3.5B valuation — was the largest funding event of the month and confirmed software supply chain as the standout segment of 2025. CyberCube's $180M growth round in cyber-insurance ratings and Sublime Security's $150M Series C in email security rounded out the late-stage tape. The seed-and-Series-A share held at 63%, the year's median. Identity and Data tied for top segment with 7 transactions each, followed by GRC (5).
The PE-take-private theme matters. Jamf, which IPO'd in 2020, becomes private again at $2.2B under Francisco Partners — a pattern we should expect to see repeat across the cohort of cyber companies that went public in 2020–2021. Veeam's acquisition of Securiti pulls data privacy and AI-governance tooling inside the data-protection platform, signaling that the post-acquisition Veeam (itself Insight Partners-owned) is consolidating adjacent categories under a single platform. Both deals are PE-backed; both bypass strategic acquirers; both happen at scale.

Two deals worth your attention
Chainguard — $280M growth round led by General Catalyst. Chainguard closed a $280M growth round at a reported $3.5B valuation — its fifth appearance in this series in three years and its second mega-round of 2025. The company's positioning as the secure-by-default container and artifact provider has now produced the deepest-funded private vendor in the software supply chain segment, and the General Catalyst lead signals continued institutional conviction in the category.
Francisco Partners' $2.2B take-private of Jamf. Francisco Partners agreed to acquire Apple device management vendor Jamf for $2.2B, taking the company private five years after its 2020 IPO. The deal continues the 2025 pattern of PE-backed take-privates in cyber — buyers are betting that operational restructuring under private ownership produces better returns than continued public-market scrutiny, particularly for companies sitting in markets where growth rates have normalized.
Companies we've covered before
Chainguard first appeared in June 2022 with a $50M Series A in Supply Chain. Five rounds in, the October 2025 deal at $280M pushes cumulative disclosed capital past $880M — the deepest-funded software supply chain security vendor in the workbook.
Securiti first appeared in October 2022 with a $75M Series C in Data security. Three years later — to the month — it exits to Veeam for $1.725B, a tidy multi-year consolidation arc in the data privacy and governance space.

Methodology
Every transaction in this brief was sourced from a primary public report and dedupe-checked against the master Pinpoint funding workbook, which now contains ~2,600 transactions back to May 2020. Funding totals reflect disclosed capital only; acquisition values are included where publicly available.
Each deal is classified against Pinpoint's normalized cybersecurity segment taxonomy — read directly off what the company says they protect and mapped to one of the canonical segments. The taxonomy has been maintained continuously since 2020 and currently covers roughly 55 segments. Identity, Data, Detection / Response, and Threat Intel have been tracked from the first month of the series; AppSec and GRC entered the following month; emergent categories (AI/LLM, Supply Chain, Quantum, Browser) are added when they first appear in vendor positioning. That normalization layer is what makes multi-year, cross-segment comparisons possible against an otherwise inconsistent vocabulary in the broader market.
