Spear’s Review

Hussein Nasser Eddin is the CEO and co-founder of global security firm Crownox, which he initially started to cater to Fortune 500 companies and international organisations, but which now also offers security solutions for UHNWs, HNWs, celebrities and royals.

Based in Jerusalem, Nasser Eddin also heads offices across the Middle East and partners with security firms across the world, including several in Latin America. He regularly works as part of the security team on major global music tours, and tells Spear’s his expertise in the Middle East contributed to the safe evacuation of 780 people during the 12-day Iran-Israel conflict in 2025. ‘We are the number one choice for UHNWs in the region.’  

He says Crownox is ‘not your typical ex-veteran security firm’, and that he and his team have academic backgrounds in fields such as Middle-Eastern politics and homeland security, which allows them to get involved in ‘many different aspects of security’, from investigations to background checks, and offer a ‘holistic advisory service’. 

Adviser Profile

Hussein Nasser Eddin is the CEO of Crownox, a premier global risk-mitigation and security advisory firm. Over the past decade, he has earned a reputation as a trusted advisor to ultra-high-net-worth individuals, ranging from globally recognised celebrities and media production leaders to chairmen, founders and C-suite executives of Fortune 500 corporations across the technology, aviation, oil and gas and entertainment industries. His clients depend on him not only for discretion but also for decisive, hands-on guidance, whether steering high-level corporate engagements or navigating delicate state-level interactions.

Throughout his career, Hussein has served as both strategist and on-the-ground problem solver; managing personal safety, coordinating executive travel, leading complex due diligence and investigative operations, and directing emergency responses in challenging global environments. He has spearheaded evacuation operations during times of crisis, most notably for children battling cancer from the Gaza Strip in 2023, 2024 and 2025 to neighbouring countries, and advised multinational firms on legal compliance and operational resilience, and the development of proactive security measures tailored to high-stakes settings.

During these years, he built a solid network of security experts and trusted ground-level responders managed by a Global Security Operations Center that he established in Cairo, Egypt, an asset that has proven invaluable during critical incidents and crisis response operations. His academic background, including a master’s degree in Middle East politics from the University of Exeter (UK) and another in homeland security from Reichman University in Herzliya, complements a diverse portfolio of advanced training in close protection, negotiations and operations in complex environments.
