Prism Security Group is a mid-size private security firm of approximately 600 employees specializing in electronic surveillance, counter-surveillance, and information security. While Ironclad Solutions sells muscle, Prism sells eyes — the ability to see threats before they materialize and to make clients invisible to threats they can't prevent. In a city saturated with surveillance, Prism's business is ensuring that the surveillance works for their clients rather than against them.

Prism's client list includes corponations seeking protection from corporate espionage, wealthy individuals seeking privacy from the Wire Taps and their competitors, criminal organizations seeking counter-surveillance against corporate and municipal monitoring, and political organizations seeking secure communications. This diverse client base means Prism is frequently protecting one client's secrets while another client is trying to steal them — a situation the firm manages through strict information compartmentalization and a policy of never, ever telling one client what they know about another.

The firm's technical capabilities are exceptional. Prism's electronic warfare suite can detect surveillance equipment at the molecular level, their counter-intrusion systems can identify network penetration attempts that most corporate security teams would miss, and their 'clean room' services — debugging a space of all surveillance devices — are the gold standard in GLMZ.
