In a shift aimed at streamlining cybersecurity communications, the Cybersecurity and Infrastructure Security Agency (CISA) has updated its protocols for distributing cyber-related alerts and notifications.
The move, effective from May 12, 2025, is designed to ensure that the most urgent and actionable information reaches cyber defenders promptly, while also addressing feedback from stakeholders regarding recent changes.
New Distribution Channels for Cybersecurity Updates
CISA, the nation’s lead agency for cyber defense, announced that cybersecurity alerts, advisories, and guidance will now be disseminated exclusively through CISA’s official social media platforms and targeted email notifications.
Updates will no longer appear on the Cybersecurity Alerts & Advisories webpage, except for information tied directly to emerging threats or major cyber incidents.
Key Technical Terms and Codes
- Alerts & Advisories: Official communications from CISA detailing vulnerabilities, threat intelligence, or mitigation strategies.
- Known Exploited Vulnerabilities (KEV) Catalog: A curated list of vulnerabilities actively exploited in the wild, maintained by CISA.
- RSS Feeds: Web feed formats used to publish frequently updated information, such as blog entries or news headlines.
- GovDelivery: A digital communication platform used by government agencies to distribute email updates to subscribers.
Rationale Behind the Change
According to CISA, the adjustment is intended to “highlight the most timely and actionable information for cyber defenders.”
The agency observed that the previous system, which listed all updates on the Alerts & Advisories webpage, sometimes buried critical threat intelligence under less urgent news.
By narrowing the webpage’s focus to only the most urgent alerts-such as zero-day vulnerabilities, active exploitation campaigns, or significant threat actor activity-CISA aims to make it easier for security teams to prioritize their response.
How to Stay Informed
CISA encourages all stakeholders and cyber professionals to subscribe to its email notifications via CISA.gov. Additionally, real-time updates will be available at @CISACyber.
For those who previously relied on RSS feeds to monitor updates-particularly for the Known Exploited Vulnerabilities Catalog-CISA recommends subscribing to the KEV topic through GovDelivery to continue receiving timely notifications.
Sample Subscription Code for KEV Updates:
text1. Visit https://www.cisa.gov/
2. Click on "Subscribe" in the top navigation.
3. Select "Known Exploited Vulnerabilities Catalog" as your subscription topic.
4. Enter your email address and confirm your subscription through GovDelivery.
Community Feedback and Next Steps
CISA acknowledged that the initial rollout of these changes confused within the cybersecurity community.
In response, the agency has temporarily paused further modifications and is actively seeking additional stakeholder input to refine its approach.
“We greatly appreciate stakeholder feedback, which played a part in this change and thank you for staying connected with CISA,” the agency stated.
As cyber threats continue to evolve, CISA’s updated alert sharing strategy underscores the importance of rapid, targeted communication.
Cyber defenders are urged to update their notification preferences and remain vigilant for further announcements as CISA continues to refine its information-sharing practices.
