While the threat of large-scale, centrally coordinated attacks remains, the rise of lone actors, transnational ideologies, and the influence of digital platforms has forced governments and international institutions to rethink how terrorism is detected, prevented, and addressed. In Europe and beyond, intelligence services are moving toward approaches rooted in multidisciplinary collaboration, local engagement, and respect for the rule of law.
Belgium’s Decentralised and Multidisciplinary Model
In response to these evolving dynamics, Belgium has adopted one of the most structurally integrated counter-terrorism frameworks in Europe. Following the 2016 Brussels attacks, a parliamentary inquiry led to the development of the “Note Stratégique Extrémisme et Terrorisme”, known as Strategy T.E.R. This approach redefined the role of intelligence by fostering closer cooperation between security services, police forces, municipalities, and social actors.
At the core of the Belgian system are decentralised platforms—Local Taskforces (TFL) and Local Integrated Security Cells (CSIL-R)—that enable the joint assessment of cases of radicalisation. Intelligence services such as the State Security Service (VSSE) and the military’s SGRS feed into these platforms alongside police and administrative bodies. The focus is not only on monitoring and intervention but also on prevention, reintegration, and tailored follow-up of individuals. Risk management is based on dynamic case-by-case evaluations, supported by a shared database and clear legal protocols. The strategy underscores the need for shared responsibility and a common operational language between all actors involved.
Germany’s Preventive Surveillance and Legal Safeguards
Germany’s domestic intelligence services have long prioritised prevention through surveillance and constitutional protection. The Federal Office for the Protection of the Constitution (BfV) leads national monitoring efforts against threats from both Islamist and far-right extremist groups. Working alongside state-level counterparts (LfVs) and the Joint Counter-Terrorism Centre (GTAZ), the BfV contributes to an early-warning system that alerts law enforcement to emerging risks.
The German model relies heavily on legal oversight to balance security with civil liberties. Intelligence services are not authorised to arrest or prosecute but play a vital role in gathering and interpreting signals of radicalisation. This information can then be passed on to prosecutors or police when a judicial response is required. Programmes for community-based prevention and deradicalisation are increasingly used to complement surveillance efforts, especially in cases involving minors, returnees, or online influencers.
Indonesia’s Intelligence-Driven and Regionally Anchored Strategy
In Indonesia, the counter-terrorism model reflects the country's longstanding experience with extremist violence. The National Counter Terrorism Agency (BNPT) leads a strategic and policy-oriented response, while Detachment 88 (Densus 88), a special police unit, executes intelligence-led operations against suspected groups and individuals. The State Intelligence Agency (BIN) plays a broader role in monitoring transnational threats and coordinating national risk assessments.
A key feature of Indonesia’s approach is its emphasis on regional and international cooperation. Through platforms such as the Bali Process and bilateral security agreements with India and China, Indonesia promotes cross-border intelligence sharing and operational readiness.
Intelligence services are also central to the country’s deradicalisation and reintegration efforts, particularly in managing the return of foreign fighters and preventing recidivism. By integrating policing, intelligence, and social policy, Indonesia seeks to address the root causes and operational realities of extremism. Intelligence services are increasingly central to modern counter-terrorism. As threats become more fragmented and less predictable, the ability to detect, assess, and act upon early signs of radicalisation while maintaining democratic safeguards has emerged as a shared priority across diverse national contexts.
