Critical infrastructure is on the front line of the war in Ukraine.

And as the conflict approaches its fourth year, there is little sign of that changing.

Strikes against infrastructure, though, are only part of the picture. Since Russia’s full-scale invasion, and even before, Ukraine’s defenders have waged an equally intense, but less visible, cyber war.
