The Society for International Executive Protection (SIX) is a global, non-profit force multiplier for professionals operating at the highest levels of executive protection. Founded in 2019 by Melvin Key, now Chairman of the Board, SIX has grown into a worldwide network of 250+ vetted members and counting, with momentum accelerating every year.

SIX isn’t just a membership, it’s an ecosystem. We bring together elite close-protection professionals to connect, collaborate, and level up. Members gain access to trusted industry resources, real-world operational insight, business-growth opportunities, and a powerful global network that opens doors to details, contracts, and careers.

Our membership spans the full spectrum of protection: private, corporate, and government agents and agencies, all operating with a shared standard of professionalism and accountability.

Beyond individual members, SIX is trusted by international corporations, FBOs, and entertainment companies that rely on us to identify, vet, and recommend qualified agents. We help verify credentials, certifications, professional standing, and reputation, because in this industry, trust isn’t optional.

If you’re serious about executive protection and serious about your future in it, SIX is where professionals align, reputations are reinforced, and opportunities are created.
