The Italian government has increased surveillance and control of submarine power and telecommunications cables.
A source familiar with the matter told Reuters.
No specific threats to Italy have been reported.
However, the move came after the discovery of leaks in the Nord Stream pipelines last week.
In Germany, they suspect that the gas leak on the branches of the Russian Nord Stream gas pipelines across the Baltic Sea is the result of deliberate actions. Denmark and Sweden also suggest that it may be a sabotage.
US President Joe Biden called the damage to the Russian gas pipelines "Nord Stream-1" and "Nord Stream-2" a deliberate act of sabotage, which became the first such statement by the American side.
At the same time, the Russian Federation began to investigate the incidents as an "act of international terrorism." And Putin accused the United States of organizing the explosions at the Nord Stream-1 and Nord Stream-2 gas pipelines.
