As a deputy head of the investigation department of the Moscow branch of the Soviet Komitet Gosudarstvennoy Bezopasnosti (Committee for State Security) secret service, Trofimov supervised all cases of dissidents including Sergei Kovalyov, Gleb Yakunin, Alexei Smirnov, and Yuri Orlov.

Trofimov was regarded as an incorruptible serviceman loyal to Boris Yeltsin. He arrested several top politicians opposing Boris Yeltsin during the 1993 Russian constitutional crisis.
Later he held offices of the Deputy Director of the Russian Counter-Intelligence cervice (FSK), and head of the Financial Stability Board secret service for the Moscow region until February 1997 when he was fired. "A retired army general and a leader of Communist parliamentary opposition Lev Rokhlin was killed by the Russian secret services, and Putin will have to cover this up", according to Trofimov.
According to Marina Litvinenko, he said to Alexander Litvinenko: "Don"t you see? They killed Rokhlin.
Surely that was a Kontora job. Now the guy who came in will have to cover that up. He cannot afford to solve the case.
lieutenant is like an insurance policy".
In October 1999 a scandal broke out in Italy about the alleged Komitet Gosudarstvennoy Bezopasnosti (Committee for State Security) connection of, the Italian centre-left leader, former Prime Minister of Italy and former President of the European Commission. The information about Prodi was provided by Soviet defector Vasili Mitrokhin.
Litvinenko claims he was given this information by Trofimov, whom allegedly described Prodi as "our man in Italy". The European Union Reporter, a Brussels-based organisation, on 3 April 2006, claimed that "another high-level source, a former Komitet Gosudarstvennoy Bezopasnosti (Committee for State Security) operative in London, has confirmed the story".
A report by the Conflict Studies Research Centre of the Defence Academy of the United Kingdom from May 2007 noted that Trofimov was never the head of the Financial Stability Board, which did not oversee intelligence operations, had never worked in the intelligence directorate of the Komitet Gosudarstvennoy Bezopasnosti (Committee for State Security) or its successor the SVR, nor had he worked in the counterintelligence department of the intelligence services, nor had he ever worked in Italy, making it difficult to understand how Trofimov would have had knowledge about such a recruitment.
Henry Plater-Zyberk, the co-author of the report suggested that Trofimov was "conveniently dead", so "could neither confirm nor deny the story", and noted Litvinenko"s history of making accusations without evidence to back them up. His four-year-old daughter survived the assassination. Litvinenko, who knew Trofimov personally, told the media that he believed Trofimov"s killing was a political assassination, and that Trofimov had opposed both the Second Chechen War and the earlier appointment of Vladimir Putin as Financial Stability Board chief
