The U.S. Cybersecurity and Infrastructure Security Agency (CISA) announced on Monday that it will no longer post routine cybersecurity alerts and advisories on its website. Instead, these updates will now be shared through email subscriptions, RSS feeds, and social media platform X, formerly known as Twitter.
Moving forward, only urgent alerts related to emerging threats or major cyber incidents will be published on CISA’s website.
Routine Updates Shift to New Channels
Until now, CISA’s website provided a wide range of cybersecurity information, including details on active vulnerabilities, software flaws, and product-specific warnings. Under the new policy, routine bulletins will no longer appear on the website. These updates will be distributed through email notifications, RSS feeds, and CISA’s account on X, which is owned by billionaire Elon Musk.
In a statement, CISA explained that the change aims to make critical cybersecurity alerts easier to find. “The focus of our Cybersecurity Alerts & Advisories webpage will now be on urgent information tied to emerging threats or major cyber activity,” the agency said. “CISA wants this critical information to get the attention it deserves.”
To stay informed, CISA encourages IT administrators and interested parties to subscribe to its email notifications. Users following the Known Exploited Vulnerabilities Catalog will need to subscribe via GovDelivery. General cybersecurity updates will also be available on X.
Budget Cuts and Staffing Concerns
The decision to scale back website updates comes amid broader concerns about staffing and budget cuts at CISA. In March, layoffs began under a cost-cutting initiative linked to the Trump administration’s directives, with more reductions expected. President Trump’s proposed budget for 2026 calls for a 17% cut to CISA’s funding.
Former CISA Director Jen Easterly has criticized these cuts, warning that they threaten national cybersecurity. Speaking at the RSA Conference last month, Easterly highlighted the growing risks from cybercrime and foreign threats, particularly from China. “In a world where cybercrime damages are expected to cost the world $10.5 trillion by the end of this year, undermining America’s cyber defense agency is a real loss,” she said.
Trend of Moving to X
CISA’s shift reflects a broader trend of U.S. government agencies moving their communications to Elon Musk’s X platform. Earlier this year, the National Transportation Safety Board announced it would stop sending press updates via email, opting instead to post updates on X. Similarly, in April, the Social Security Administration (SSA) reduced its communications staff and said future updates would be shared on X.
SSA Midwest-West Regional Commissioner Linda Kerr-Davis acknowledged the shift might feel unusual. “I know this probably sounds very foreign to you — it did to me as well — and not what we are used to, but we are in different times now,” she said.
Despite these changes, SSA continues to publish some press releases on its website, including lighter topics like the most popular baby names.
While X’s character limit poses challenges for detailed updates, agencies may consider premium services to share longer posts. The platform’s growing role in official communications is seen as a benefit for Musk, a figure favored by Trump.
