Deputy National Security Adviser for Cyber Anne Neuberger is traveling to Europe today for a week of meetings with U.S. partners on cyber issues, including the defense of Ukraine, senior administration officials told reporters.

Neuberger will start in Brussels w/ meetings w/ EU counterparts & NATO officials on cyber resilience, a sr admin official said, "including deterring, disrupting, and responding to further Russian aggression against Ukraine, neighboring states, and in our respective countries."

After Brussels, Neuberger will travel to Warsaw for meetings with Polish officials and reps from Baltic govts.

She'll also meet with reps from the "Bucharest Nine" group of eastern NATO allies, and she'll meet virtually with French and German officials.

Goal is to ensure that U.S. and partners "are prepared for any cyber-related contingency and prepared to respond in the current environment," SAO said.

They'll also discuss "how we will coordinate and support Ukraine, and each other, in the event that cyberattacks occur."

U.S. has been "working closely with Ukrainians to harden their defenses, and we will continue to do so," SAO said.

At the same time, "we are realistic about what we can achieve, and also focused on ensuring we have incident response capacity available to them, if needed."

The Biden administration has been discussing cyber incident response support with European allies, in case they need to collectively surge resources to help Ukraine respond to cyberattacks from Russia, the SAO said.

SAO: "While there are not currently any specific credible threats to the U.S. homeland, we are mindful of the potential for Russia to consider escalating its destabilizing actions in ways that may impact others outside of Ukraine."
