Jakarta's chief of police says Indonesia is hunting terror cells believed to have been involved in the attack on the capital.
Two civilians and five attackers died in Thursday's gun and bomb assault in a busy commercial district.
Insp Gen Tito Karnavian told the BBC the actual attacking cell was "tiny" and had been "neutralised", but was linked to cells in Sulawesi and Java.
The Islamic State (IS) militant group has said it was behind the attack.
It released a statement online saying it had been carried out by "soldiers of the Caliphate", targeting "citizens of the Crusader coalition" against the group.
Indonesian President Joko Widodo has condemned the "acts of terror".
He tweeted on Friday that there was "no place for terrorism on Earth" and that "every citizen in the world" needed to fight it.
Security forces battled militants for hours on Thursday in a major business and shopping district of Jakarta before bringing the situation under control.
It ended when two of the attackers were killed in a suicide bombing, said police, with the other three killed in gun battles.
A Canadian and an Indonesian national, both civilians, also died and at least 20 people were injured.
Indonesia - which has been attacked by Islamist militants several times - had been on high terror alert amid IS threats to target Jakarta.
Insp Gen Karnavian said Indonesia had significantly developed its understanding of domestic terror networks since the 2002 Bali bombing, adding that one plot had been foiled at the end of 2015 and a number of people detained.
The detainees included a man who said he had been instructed by Bahrum Naim, an Indonesian currently believed to be with IS in Syria.
Naim has been linked to the IS-allied East Indonesia Mujahidin Group (MIT), which is based on the island of Sulawesi.
The police chief said some 1,000 people linked to radical networks had been brought to justice in Indonesia since 2000, but that some had since been released from prison and had "the potential to pose a threat".
He said Indonesia needed to strengthen its own capabilities and information sharing with other countries, because the terror threat was "not home grown in Indonesia but it is part of a global network".
Islamist attacks in Indonesia
Indonesia has suffered militant attacks in the past, but has been relatively successful in curbing home-grown Islamist extremism after a spate of attacks in the last decade. Some of the deadliest include:
The Islamic State threat in South East Asia
