Cybersecurity mergers and acquisitions remained active through the first half of 2026, but deal counts and disclosed value tell different stories. Kroll reported 75 announced transactions worth $2.2 billion in disclosed value in Q1 2026; SecurityWeek counted 426 cybersecurity deals in 2025, while a handful of very large transactions heavily influenced that year’s disclosed-value total. For buyers, boards and deal teams, the practical task is to judge whether an acquisition adds a useful security capability—and to identify, price and control cyber risk before and after close.
What do the latest cybersecurity M&A figures show?
They show continued transaction activity, not a single, directly comparable measure of market size. Trackers differ in what they count, and disclosed deal value covers only transactions with reported figures. Treat each number as a result from its named source and period.

| Measure | Reported result | How to read it |
|---|---|---|
| Q1 2026 cybersecurity transactions | 75 announced transactions; $2.2 billion in disclosed value (Kroll, Spring 2026 update) | Kroll said no transaction in the quarter exceeded $1 billion. This is a quarterly snapshot, not a full-year result. |
| 2025 cybersecurity deals | 426 deals, including 334 involving pure-play companies (SecurityWeek, 2026 report on 2025) | SecurityWeek’s count was 5% above its 2024 count. It includes deals with a cybersecurity component and may omit transactions without English-language announcements. |
| 2025 disclosed deal value | $92.5 billion across 74 deals; $84 billion across 63 pure-play deals (SecurityWeek, 2026 report on 2025) | These are disclosed-value subsets, not the value of every deal in the tracker. Google’s planned $32 billion acquisition of Wiz accounted for much of the year-over-year increase. |
| Q2 2026 activity | Volume tracked at a pace consistent with 2025’s record-setting levels (Kroll, Summer 2026 update) | Kroll described aggregate deal value as subdued; the update does not establish a full-year 2026 outcome. |
These figures should not be added together or treated as if Kroll and SecurityWeek used identical inclusion rules. SecurityWeek compiled company announcements and other reporting; its count is a tracker result rather than a complete census. Kroll’s quarterly updates are snapshots with their own scope. A separate figure in the UK government’s 2026 sector analysis relays Kroll’s estimate of $63.3 billion in global cybersecurity M&A value by Q3 2025. That estimate is not directly interchangeable with SecurityWeek’s annual total of disclosed values across 74 deals.
Which cybersecurity capabilities are attracting buyers?
The available trackers point to a mix of platform expansion, specialist capability and emerging security needs. They do not establish one universal reason for each acquisition, or show that every category is growing.
#1 Best Overall
Governance, data protection and identity
SecurityWeek counted 82 governance, risk and compliance (GRC) deals in 2025, a five-year peak in its dataset. It counted 63 data-protection deals, up from 44 in 2024, and 43 identity deals, up from 28. Those counts indicate activity in the categories as SecurityWeek classifies them; they do not, on their own, prove why buyers made those deals.
AI, cloud, exposure and newer security areas
SecurityWeek counted 13 AI-security deals in 2025, compared with eight in 2024. In its 2026 updates, Kroll identified AI-enabled defense, cloud security and exposure management among areas of buyer interest. Its Q2 update also highlighted acquisitions involving operational technology (OT) and Internet of Things (IoT) security, browser security, identity security and AI-agent governance. These are separate firms’ descriptions and categories, not a shared classification system.
Platforms, managed services and geographic reach
Kroll describes buyers pursuing platform consolidation and differentiated capabilities. SecurityWeek interprets the strength of the $100 million to $999 million deal range and large transactions as evidence of strategic scaling, but its data do not show that one deal size is inherently preferable.

It cites Sophos’s completion of its Secureworks acquisition in February 2025, alongside examples of UK providers expanding through acquisitions. For a buyer, the strategic question is whether a deal adds specialist expertise, regional reach or managed delivery that fits the operating model—not simply whether it increases scale.
Rank #3
Where are tracked cybersecurity deals taking place?
In SecurityWeek’s 2025 tracker, the United States was involved in 288 of 426 deals—roughly 67%—and the UK was involved in 64, making it the second-largest hub in that dataset. SecurityWeek listed 34 deals involving Israel. These are tracker counts of deal involvement, not necessarily exclusive counts of buyers or sellers based in each country.
How should a buyer assess cyber risk in an acquisition?
Cyber diligence should be a transaction workstream, not a last-minute document check. The National Association of Corporate Directors (NACD), in an M&A boardroom tool dated April 16, 2026 and produced with Internet Security Alliance partner content, recommends an experienced team, technical assessment and explicit planning for remediation and integration. These are practical recommendations, not evidence that every transaction leads to an incident.
Before signing or closing
- Staff for the deal’s technical and regulatory demands. Use people who understand cybersecurity, applicable regulatory requirements and transaction timelines.
- Combine interviews and document review with technical testing. A target’s own team may not know every vulnerability; technical review can surface risks that interviews and policy documents miss.
- Identify gaps and put a cost on the work. Assess security and compliance gaps, review whether cyber insurance is sufficient, estimate remediation costs and include expected security work in the transaction economics.
- Understand the systems before connecting them. Investigate the target’s systems and vulnerabilities before close or integration pressure encourages quick connections.
After close: control integration
- Govern new access. Set approval and oversight for access grants and integration work rather than allowing permissions to accumulate informally.
- Plan and monitor connectivity. Design how networks will connect and monitor those links as the companies’ environments are brought together.
- Rehearse a joint incident response. Agree how the two organizations will coordinate decisions and response actions, then practice the process before an incident forces teams to improvise.
- Set the combined security operating model. Define staffing, technology, policies and budget for the combined organization.
During a divestiture
- Protect data and intellectual property. Specify how critical information will be safeguarded as teams, systems and responsibilities change.
- Make continuing cyber services explicit. If the remaining company will provide security or other cyber services to the divested business, define those services and their management in a transition-services agreement.
The FBI advisory quoted in NACD’s April 2026 tool states: “The FBI assesses that ransomware actors are very likely using significant financial events, such as mergers and acquisitions, to target and leverage victim companies for ransomware infections.” This is the FBI’s assessment as reproduced in NACD’s guidance.

How can deal teams compare acquisition opportunities?
No single company type, deal size or capability is automatically the best choice. A useful comparison weighs the strategic addition against the work and risk required to realize it.
Quick Recap
Best Value
- Capability fit: Does the target add a relevant capability, such as identity, GRC, data protection, cloud, exposure management, OT/IoT, browser or AI-agent security?
- Scale and platform role: Is the asset intended to become a platform or to fill a narrower capability gap? SecurityWeek’s data show activity across deal sizes but do not establish that either role is inherently superior.
- Integration and remediation burden: What technical debt, compliance gaps, access risks and remediation costs emerge from diligence? Can the teams connect systems safely?
- Geographic and service expansion: Will the deal add regional reach, managed delivery or specialist expertise—and can the buyer operate and support that addition?
