Frequently asked questions
How many Cybersecurity deals does the index track?
41 deals so far, 11 of them announced in the last 30 days. The count changes as the daily pipeline verifies new announcements; the full dataset is downloadable as CSV or JSON from the hub.
What counts as a Cybersecurity deal here?
This cut includes announced acquisitions of security software and security services companies. Sector and buyer type are taken from the announcement text; rows where those had to be inferred are marked medium confidence in the JSON.
Why do some Cybersecurity deals show no value?
Because the parties did not publish one. We record a value only when a dollar figure appears in the public source and never estimate, so undisclosed means undisclosed.
