According to Macron, the number of soldiers who will protect places, such as schools and churches, will more than double - from 3,000 soldiers to 7,000, reports AP.
The president's decision is a direct reaction to the knife attack in Nice where three people have died and several have been injured.
Following the incident, France has raised the level of terrorist threats in the country to the highest possible level.
The incident occurred almost two weeks after teacher Samuel Paty was beheaded in a suburb of Paris by an 18-year-old Islamist.
After the assassination, Emmanuel Macron made a series of statements about Islamism, which in turn triggered a political crisis between France and Turkey and led to a boycott of French goods in several parts of the Arab world.
