Ferrari finished the 2023 season in third place in the world championship, some 454 points behind Red Bull, who won all but one grand prix last season - with Carlos Sainz interrupting its streak in Singapore.
Vasseur stressed that the Maranello outfit has to improve in every area in order to chip away at the advantage that Red Bull has, rather than focus on replicating one major gain the world champion's may have.
“I think the mistake would be to imagine that Red Bull, they have a magic bullet of five-tenths or that we made a step on something,” he said.
“The performance is coming from everywhere into the company, on the fact that we are able to produce parts quicker, on the fact we have better reliability.
“We gave up too many points this season for different reasons, for reliability, for disqualification in Austin, for impeding in quali. This is clearly where we have to work.
