From the data this site collects, we chart only the sources whose "real event dates" span a meaningful period. Based on actual event dates — when a vulnerability was confirmed exploited, when a filing was submitted, when a contract started — rather than collection timing, this shows when and how much activity occurred.
Note: sources collected only as a recent snapshot (Federal Register, arXiv, clinical trials, etc., whose publication dates reflect collection timing) are excluded from this timeline, since they would show collection timing rather than reality.
Known Exploited Vulnerabilities (KEV) added per month
How many vulnerabilities CISA confirmed as actively exploited were added each month. Dates are the catalog-add date (a real event date).
Known Exploited Vulnerabilities (KEV) added per month. 657 tracked from 2023-07 to 2026-06, peaking in 2025-03 with 32. These are real dates a flaw was confirmed as exploited — a steady cadence of new entries each month.
SEC filings submitted per month
How many SEC filings the companies this site follows submitted each month. Dates are actual filing dates.
Tracked SEC filings per month. 544 from 2024-07 to 2026-06, peaking in 2026-04 with 79. Dates are real filing dates for the companies this site follows.
Federal contracts by start year
The federal contracts this site tracks, counted by the contract start year. Each bar also shows that year's contract value (cumulative).
Tracked federal contracts by start year. 500 contracts, most starting in 2020 (56). This site collects AI-related and major contracts, so counts reflect that focus rather than all federal contracting.
Sources (primary)
All are aggregated from this site's collected set, based on each source's real event date (KEV = exploited-confirmed date / SEC = filing date / contracts = start date). This site is not an official U.S. government website.
