Esperanza Casteleiro Llamazares is a pioneering figure in Spanish intelligence, whose career stands as a testament to resilience, discretion, and unwavering dedication to national service. Born in Madrid in 1956, she has spent decades working quietly yet effectively in the shadows, rising through the ranks of Spain’s intelligence community with distinction, competence, and calm determination.
She began her career in the Centro Superior de Información de la Defensa (CESID)—the predecessor to the Centro Nacional de Inteligencia (CNI)—where her sharp intellect, strategic mind, and ability to handle sensitive operations quickly earned respect. Her expertise spanned both national security and international affairs, and she held crucial posts in areas demanding the highest levels of trust and integrity.
In 2020, she was appointed Secretary of State for Defense, becoming one of the highest-ranking women in Spanish defense, and in 2022, she broke further ground by being named Director of the CNI, becoming the second woman ever to lead the agency.
Through turbulent political climates and delicate missions, Casteleiro has been a steady, thoughtful presence—someone who inspires confidence not through grandstanding, but through competence, discretion, and tireless public service. Her story is one of a woman who climbed to the highest echelons of national security not through privilege, but through perseverance—an inspiring symbol of leadership, service, and integrity in modern Spain.
We are affiliated with the Ministry of Defence and collaborate with various governmental agencies, including the state security forces and bodies. We always operate under the supervision and control of the executive, legislative, and judicial powers. Every day, we work to protect Spanish society from various types of threats. We strive to anticipate the emergence of these threats by obtaining information and transforming it into intelligence, with the goal of supporting authorities in decision-making. We believe that intelligence is the best defense for our society.
The National Intelligence Centre (CNI) of Spain is the silent sentinel of the nation—working behind the scenes to protect democracy, defend national interests, and ensure the safety of its citizens in an increasingly complex and unpredictable world. More than just an intelligence agency, the CNI represents the courage, dedication, and professionalism of those who serve without recognition, often in the shadows, driven by duty rather than praise.
Founded on principles of legality, accountability, and loyalty to Spain’s democratic institutions, the CNI operates at the cutting edge of security, cybersecurity, counterterrorism, and global intelligence. Its mission is not only to gather and analyze critical information, but to anticipate threats, prevent crises, and empower national decision-makers with the insight they need to lead wisely and decisively.
At its core, the CNI is a story of quiet heroes—men and women committed to peace, stability, and the defense of freedom. It is an institution that inspires trust, exemplifies service, and proves that true strength often lies in the unseen work of those who protect a nation from the shadows.
