Romulan Tal Shiar
From Star Trek : Freedom's Wiki
The Tal Shiar is the elite Intelligence organisation of the Romulan Star Empire. It is a highly respected and feared organization whose main objective is to enforce loyalty of Romulan citizens to the government and obtain enemy secrets, most notably from the Federation and the Klingon Empire. Their presence is often undetectable and their methods covert. At times, the operations of the Tal Shiar goes above the control of the government itself, as the agents themselves have the power to overrule the direct authority of most military commanders, which they utilize with little fear of reprisal.
