CISAの規制対応状況について、Cybersecurity Dive公式の報道記事（https://www.cybersecuritydive.com/news/cisa-departures-trump-workforce-purge/749796/）で確認できます。Existing references describe CISA's general mission and distinction from NIST; none mention staffing levels or workforce reductions, so there is no overlap, and this is a distinct claim (2025 staffing) from the first finding (2018 founding).具体的には「'roughly 1,000 employees' have departed, reducing CISA 'down to around 2,200'... 'Between buyouts, early retirements and layoffs, we've lost about 1,000 people.' More than 600 employees left CISA as part of the second and most recent round of departures, which were part of what the Department of Homeland Security called its Workforce Transition Program.」といった記載が確認できます。限界として、規制対応の状況は更新されうるため、この内容は取得時点のものです。適用範囲がどこまでかは、このSourceだけでは確認できない場合があります。 The figures are based on an agency employee's estimate as quoted in the article as of June 2025 and may not exactly match CISA's official personnel records at any given point.Current Statusとして、2026年08月27日に当該Sourceを取得し、上記の内容を確認しました。Source種別としては、これは第三者であるCybersecurity Diveによる報道であり、企業の自己申告とは性質が異なりますが、報道時点の取材内容に基づくものです。
