Official Message

Since the end of the civil war in 2002, the security landscape in Sierra Leone has evolved dramatically, with considerable progress in structural reforms and service delivery. There has been a paradigm shift from state-centric to human security. This current security arrangement requires core security sector institutions and government Ministries, Departments and Agencies to work in tandem and complement one another in pursuance of our collective security and progress.

The Office of National Security (ONS) is positioned to play the critical role of coordinating these efforts, as enshrined in the National Security & Central Intelligence Act (2002).

Over time, the ONS has made deliberate efforts to promote the culture and practice of security across government, thereby linking security strategy to development objectives. The ONS supports His Excellency the President, as Chairman of the National Security Council, by offering high-quality advice and driving efforts to ensure decisions are implemented professionally. The ONS coordinates the Early Warning and Early Response (EWER) mechanism to prepare for, and respond effectively to, threats and hazards that affect Sierra Leone’s national security. These include public order and social issues, corruption, organized crime, economic security, health and environmental issues, terrorism, and external threats. While EWER is coordinated at the national level, it is also carried out locally through decentralized security committees, including Provincial, District, and Chiefdom Security Committees (PROSECs, DISECs, and CHISECs), as embedded in the Standard Response Guidelines for the National Security Architecture.

While Sierra Leone, as a post-war nation, continues to face internal security challenges and external threats, including border incursions and terrorism in the sub-region, the ONS remains committed to its core mandate of coordinating the security sector’s efforts to mitigate and respond to threats to national security. In doing so, the ONS continues to contribute to the enabling environment for peace and development.
