Who is funding cybersecurity in 2026? What 527 tracked deals show
Our deal tracker has logged 527 cybersecurity transactions between January 6 and November 3, 2026: 299 acquisitions and 228 funding rounds. Every entry links back to a public source, and nothing here is estimated. Below is what that record shows, and just as importantly, what it can’t.
Who is writing the cheques
Counting the funding rounds each firm took part in, the most active investors in the tracker are:
- Ten Eleven Ventures and Accel: 8 rounds each
- Bessemer Venture Partners: 7
- Ballistic Ventures, Sequoia Capital and Insight Partners: 6 each
- Evolution Equity Partners, Cyberstarts and Team8: 5 each
The mix is telling. Two cybersecurity-only specialists (Ten Eleven, Ballistic) sit level with generalist giants (Accel, Sequoia, Insight), and Israeli-founded platforms (Cyberstarts, Team8) hold their own against much larger funds. You can see all 100 venture firms we rank, with a battle card for each, on our Venture Capitalists page.
Where the rounds are landing
Of the 228 financings, the most common stages are Series A (58 rounds), Seed (40) and Series B (34), followed by rounds reported only as “Early Stage” (20) and Series C (16). Early-stage money dominates the count, which fits the broader picture of a market still funding new categories rather than only topping up incumbents.
What is being bought and funded
By sector label, Risk & Compliance leads the tracker (78 deals), followed by Security Consulting & Services (71), AI Security (63), Identity & Access Management (46) and SecOps & Incident Response (37). AI Security stands out as a category that barely existed as a line item a few years ago and now ranks third.
The biggest disclosed deals
- Zurich’s acquisition of Beazley: $11.0B (March 2). Beazley is a London insurer, so this is an insurance-sector deal that our tracker files under Risk & Compliance rather than a security-vendor acquisition.
- Proofpoint’s acquisition of Varonis: $6.3B (October 15)
- Accenture’s package deal for Dragos, runZero and NetRise: reported together at $4.2B (June 18). We list the three companies separately but the price covers all three.
- EigenQ‘s business combination with Silicon Valley Acquisition Corp.: $3.0B (June 17), a business combination with a special-purpose acquisition company rather than a conventional sale
- Visa’s acquisition of BioCatch: $2.4B (August 3)
- IonQ’s agreement to buy Elisity: up to $1.3B (October 12), as announced
- Cyera’s acquisition of Oasis Security and Keyfactor‘s financing: $1.0B each (July)
Acquirers appearing most often are CrowdStrike (5 deals) and Check Point (4), followed by Palo Alto Networks, Cisco, Accenture, Databricks and Cyera (3 each). CrowdStrike’s two newest entries, Fiddler AI ($400M) and Dreadnode ($95M), were logged on November 3 from press reports of a combined price of about $495M, so treat those figures as reported rather than confirmed.
How to read these numbers
- The tracker records deals we can source publicly. Many private rounds never disclose investors or amounts, so counts understate every firm’s real activity.
- Only 6 of the 527 deals in the tracker publicly name their M&A advisors, so advisor activity is thin by comparison.
- Recent months look quieter (39 deals in September and 43 in October, versus 65 in January and June; November has only just begun, with 3 so far), but late-reported deals get added after the fact, so don’t read that as a slowdown yet.
