"Faced with the threat of international terrorism we need to be much more ambitious... in terms of intelligence," said Mr Fenech.
All trace of suspects lost - Hugh Schofield, BBC News, Paris
The committee chairman George Fenech says the aim of the report is not to designate guilty parties, but to make the general point that France's intelligence system failed.
All three of the of the attackers at the Bataclan, for example, were known to the security services and yet all trace of them had been lost.
Part of the problem, the committee says, is a multiplicity of competing agencies and no clear vision of which does what.
For example, the national police and gendarmes have separate intelligence arms and the Paris police have a third, with the result that when one of the Charlie Hebdo attackers moved from Paris some time before the attacks, he disappeared from the radar.
The six intelligence agencies currently operating in France should be merged into a single agency directly under the prime minister's authority, the commission said.
This would improve information-sharing and make it easier for foreign agencies to know who to deal with.
