Gareth Williams was low risk and there is no evidence before or after his death that he was targeted because of his work, according to evidence from an anonymous witness at his inquest.
The woman is referred to only as SISF - a former senior operational officer in the secret service who was in charge of the vetting and training of staff when Gareth died.
In theory, SISF agreed, if he carried out unauthorised searches of the database, hinted to friends and family that he was a spy or had bought women's clothes, it could have compromised him.
However, she said that an internal review suggested that:
There was less to these concerns than meets the eye.
There is no evidence that these actions came to the attention of a third party - let alone a hostile third party.
She assured the coroner, Fiona Wilcox, that lessons had been learned. She said everyone was very aware of their responsibilities since his death.
However, Mr Williams' family broke down and proceedings had to be halted when the inquest was told that no disciplinary action had been taken against his line manager.
