Emergency rules giving French police wider search and arrest powers were introduced after Islamist gunmen and suicide bombers killed 130 people in and around Paris in November 2015.
Macron, who reviewed national security with defence chiefs following Monday night's suicide bomb attack on a concert venue in northern England, said he would ask lawmakers to extend the special powers - due to expire in mid-July - until Nov. 1.
The attack in Manchester, claimed by ISIS, killed 22 people and wounded dozens more. It struck a chord in France where more than 230 people have died in the past two years in attacks by Islamist terrorists.
Three weeks into his presidency, and facing parliamentary elections in June, Macron will want to be seen as being decisive in dealing with the threat of attacks after his presidential rivals portrayed him as weak on security matters.
A statement by the Elysee palace said Macron told his government to devise additional measures for countering the security threats beyond the emergency powers and produce a draft bill to put to parliament in the coming weeks.
He also gave instructions for a task force comprised of all the French security services to be swiftly established to coordinate actions against attacks.
Earlier, Interior Minister Gerard Collomb said French authorities had learned from British investigators that the suspect in the Manchester bombing, British-born Salman Abedi, had travelled to Libya and probably Syria.
"Today we only know what British investigators have told us - that someone of British nationality, of Libyan origin, suddenly, after a trip to Libya and then probably to Syria, becomes radicalised and decides to carry out this attack," Collomb told BFMTV.
The Manchester attack had parallels with the November 2015 ISIS attack on the Bataclan concert hall in Paris - one of several bombings and shootings on the same night in the French capital. Islamic State also claimed responsibility for the Paris attacks.
The performance of France's intelligence services have come under close scrutiny since the November 2015 attacks, and Collomb said that Britain could just as easily have been the target then as well.
"What people say is that they hesitated to strike in France or Britain and that, at the time, Daesh's (ISIS') target was not yet completely decided and so it could have happened in Britain then," he said.
Collomb said security had been stepped up at the star-studded Cannes Film Festival being held in the south of France.
"We are taking special measures everywhere," the minister said.
