CISA Releases Binding Operational Directive 26-02 on Mitigating Risks from = End-of-Support Edge Devices [ https://www.cisa.gov/news-events/directives/b= od-26-02-mitigating-risk-end-support-edge-devices?utm_source=3DBOD26-02&utm= _medium=3DGovDelivery ] 02/05/2026 3:00 PM EST=20

Today, the Cybersecurity and Infrastructure Security Agency (CISA) issued B= inding Operational Directive 26-02: Mitigating Risk From End-of-Support Edg=
e Devices [ https://www.cisa.gov/news-events/directives/bod-26-02-mitigatin= g-risk-end-support-edge-devices?utm_source=3DBOD26-02&utm_medium=3DGovDeliv= ery ]. This directive requires federal agencies to identify edge device har= dware and software that is approaching or has reached end-of-support (EOS),=
and to take immediate action to address unsupported devices operating on f= ederal networks.

*Key Actions:*


* Update vendor supported edge devices running EOS software=20
* Inventory all devices that are EOS or will become EOS within the next 1=
2 months=20
* Remove EOS devices from networks and replace them with vendor-supported=
devices that receive security updates=20
* Establish a process for continuous discovery of edge devices and regula= rly update your edge device inventory=20

For detailed guidance, see Binding Operational Directive 26-02 [ https://ww= w.cisa.gov/news-events/directives/bod-26-02-mitigating-risk-end-support-edg= e-devices?utm_source=3DBOD26-02&utm_medium=3DGovDelivery ].

*Additional Resource:*

CISA, in collaboration with the Federal Bureau of Investigation and the UK= =E2=80=99s National Cyber Security Centre, also released a fact sheet, Redu= cing the Attack Surface for End-of-Support Edge Devices [ https://www.cisa.= gov/resources-tools/resources/reducing-attack-surface-end-support-edge-devi= ces?utm_source=3DEdgeDeviceAttackSurface&utm_medium=3DGovDelivery ], sharin=
g best practices for all organizations. The fact sheet includes examples of=
edge device exploitation by nation-state threat actors and mitigation guid= ance based on the actions required for federal agencies in BOD 26-02. For m= ore information, read the fact sheet [ https://www.cisa.gov/resources-tools= /resources/reducing-attack-surface-end-support-edge-devices?utm_source=3DEd= geDeviceAttackSurface&utm_medium=3DGovDelivery ].

As the nation=E2=80=99s cyber defense agency, CISA strongly urges all organ= izations to implement edge security best practices and mitigations as a mat= ter of national security.
