Products
Cyber Operations
Defensive cyber operations, threat hunting and security engineering for government networks. It is staffed entirely by cleared personnel working inside accredited environments, which makes recruiting the binding constraint on how fast the practice can grow.
sosi.com
IT and Network Services
Network engineering, systems administration and enterprise technology support for federal agencies. It covers both fixed garrison networks and deployable communications infrastructure, which requires staff willing to work in austere overseas locations.
sosi.com
Logistics and Base Operations
Supply chain, maintenance and facilities support for military installations at home and abroad. These contracts are large, long-running and operationally demanding because they must function in austere environments.
sosi.com
Intelligence Solutions
All-source analysis, targeting support and intelligence operations staffing for defence and intelligence customers. The work is performed by cleared analysts embedded with government units, frequently at deployed locations where commercial staffing is difficult to arrange.
sosi.com
Linguist Services
Interpreters, translators and language analysts supplied to military and intelligence customers. It is the business the company was founded on, and it still requires recruiting and clearing native speakers of languages the government cannot source internally.
