Longfield Intel / Coverage / Cybersecurity

Who is buying whom in enterprise security.

Longfield Intel researches acquisition activity across the security sector and writes it up for the companies it affects. Not news summaries. The transactions, the valuations, and what the pattern means for whoever is still independent.

Two bar charts comparing 2025 deal count and disclosed value across cloud security, identity, security operations and governance and compliance.
From the current sector report. Consolidation takes a different shape in each part of the market. Cloud security posted the highest disclosed value on the fewest deals. Governance and compliance had the most deals and the smallest tickets. Sources: Momentum Cyber, SecurityWeek.

How this differs from what you already have

Most competitive intelligence you can buy is monitoring. It tells you what changed. That is genuinely useful, and it is not the same thing as knowing what the change means for you, which is the part that takes work.

Every claim in these reports is cited inline. Where a figure comes from a deal tracker, the report names the tracker. Where two trackers disagree, and in this market they disagree constantly, the report shows both numbers instead of quietly picking the more convenient one.

That last habit is the whole method. A market map is worth something because you can check it.

What I publish

Coverage

Current work concentrates on enterprise security, where acquisition activity has been heaviest and the independent field is thinning fastest.

Bar chart of disclosed cybersecurity acquisition value by year from 2019 to 2025, showing a 2021 peak, a trough in 2024, and a record in 2025.
Disclosed value collapsed by roughly two thirds between 2021 and 2024, then set a record in 2025. The dashed line marks where Kroll's figure for 2021 differs from Momentum Cyber's, which is the sort of disagreement these reports show rather than resolve by preference.

Prepared August 2026. Category-wide analysis, no subject company.

How engagements work

Reports are commissioned individually, or kept on a quarterly refresh. The refresh is where most of the value sits. A market map is worth considerably more when it is still accurate six months later, and this market moves fast enough that most of them are not.

Longfield Intel is independent. It takes no fees from the companies it writes about, and it does not act as a broker or an intermediary in any transaction it covers.
