Environment

CrowdStrike Falcon
Affected Falcon Sensor Versions

Resolution

Sensors running on affected assets in your CrowdStrike CID need to be upgraded prior to the date associated with your subdomain as seen in Step 1. To find affected assets, follow the steps below.

Use the link below for your subdomain to review a dashboard report of affected endpoints
- US-1 (April 1, 2026, 2000 UTC)
- US-2 (March 31, 2026, 2000 UTC)
- EU-1 (March 30, 2026, 2000 UTC)
- US-GOV-1 (March 23, 2026, 2000 UTC)
Alternatively, from the Falcon console, navigate to Next-Gen SIEM > Dashboards and search all dashboards for falcon_cloud_ssl_certificate_rotation to review affected endpoints
Any assets running affected Falcon sensor versions must upgrade to one of the versions listed in the table below before the deadline to prevent interruption of service and protection. See Cause section for more details

The following hyperlinks assume your CrowdStrike Falcon console is hosted on the US-1 subdomain (falcon.crowdstrike.com). If you log in to Crowdstrike from a different URL, replace the subdomain in the link's address with your own (e.g. falcon.us-2.crowdstrike.com).

For guidance on how to update sensors, see Sensor Update Policies in CrowdStrike documentation.

Note: All sensor versions listed in the Upgrade To column will trust the new cert chain, though CrowdStrike recommends upgrading any unsupported assets to supported sensor versions.

Cause

The SSL certificate for the CrowdStrike Falcon console is being replaced, in advance of the cert's expiry. Older Falcon sensor versions do not support the new intermediate certificates in the cert chain and, as a result, will need to be upgraded to a newer sensor version prior to the deadlines provided. While the cert rotation was originally slated to take place on March 16, 2026, CrowdStrike has since extended this deadline.
