The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has announced that, moving forward, it will publish only the most urgent alerts related to emerging threats or large-scale cyber activity on its official website. Other communications — including updates to vulnerability catalogs, security guidance, and product-specific advisories — will be disseminated via email newsletters, RSS feeds, and the social platform X.
Until now, CISA’s website alert section covered a wide array of topics, ranging from actively exploited vulnerabilities and flaws in industrial equipment to issues in smart TVs. The focus will now shift toward truly critical information that demands immediate attention and must remain easily accessible.
Those wishing to stay informed are encouraged to subscribe to the agency’s email notifications or configure an RSS feed. For example, to monitor updates to the Known Exploited Vulnerabilities (KEV) catalog, one must subscribe via GovDelivery. Key updates will also be posted on X.
These changes raise a pressing question: could they be linked to internal cutbacks within the agency itself? As early as March, CISA began reducing staff as part of the DOGE initiative — a government cost-cutting program aimed at departments interfacing with Elon Musk’s business empire. Further layoffs may be imminent, especially amid Donald Trump’s proposal to slash the agency’s 2026 budget by 17%.
Former CISA Director Jen Easterly has already criticized the proposal, warning that weakening the agency’s capabilities in the face of escalating global threats and multibillion-dollar cybercrime losses would gravely undermine the nation’s defense posture. She reminded the public that Chinese hackers had previously breached the United States’ critical infrastructure.
Interestingly, CISA is not alone in shifting communications to X. Following a series of aviation disasters in February, the National Transportation Safety Board declared it would abandon email alerts in favor of updates through its X profile. Similarly, in April, the Social Security Administration began downsizing its press office, announcing it would retire traditional press releases and “letters to colleagues.” From now on, all updates will be available exclusively on X.
While 280 characters can hardly convey complex, high-stakes information, perhaps federal agencies will now subscribe to X Premium for the privilege of longer posts. In any case, this trend clearly plays into the hands of one of Donald Trump’s closest billionaire allies. In today’s climate, cybersecurity priorities are increasingly eclipsed by political ambitions.
