Security Industry Specialists (SIS) is a boutique security services firm that designs and runs tailored security programmes for corporate clients. Its work spans physical security, executive protection, investigations, risk analysis, travel support and intelligence operations. Rather than selling a standard package, SIS builds each programme around the client, and its teams are expected to align with client culture, values and policies. Sectors served include technology, entertainment and consumer products.
Two capabilities anchor its operations. The 24/7/365 Fusion Center combines an around-the-clock operational tool with experienced personnel to support client security programmes continuously. Alongside it, a Training and Development Program delivers more than 1,000 technical, specialised and soft-skills courses through interactive, video-based, scenario-based and instructor-led formats. Personnel operate across a range of environments, including offices, campuses, laboratories, distribution centres, data centres and client residences.
The company maintains offices across North, South and Central America. Its stated practices include clear invoicing without unnecessary fees or percentages, regular performance reviews, employee perks and specialised development opportunities, with an emphasis on retention and the development of security leaders. Newsweek has recognised SIS as one of its "Greatest Workplaces for Diversity". Further detail is available at https://sis.us/.
