After a bit of research I have not been able to find a good answer to this question. I will accept recommendations to third party solutions as an answer if they work.
We are worried that a certain employee is going to send company data, excel, word etc. to a recently terminated employee. We have taken the steps of letting all employees know that sending privileged and private company information is a criminal offense which we will seek both criminal and civil remedy for.
We are thinking of implementing Spector Pro on the employees desktop for audit purposes. What we need is a mechanism to prevent the data leakage.
Does anyone know of a way to prevent a user or users (policy or group based) that will prevent specific attachments from being sent (either generically or to specified recipients or domains)?
Thanks in advance.
