Of course, as anyone will tell you, one of the main reasons for outsourcing is the financial benefits derived from it. But one must consider what the security risks are and whether they are worth the savings. The CIO (Chief Information Officer), Chief Security Officer and other officials concerned must always ensure that the firm or company is not exposing itself to unnecessary security risks in the process.
These officials should first take certain security issues into account. One must bear in mind that officials and employees not really from your firm are going to have access to your computer systems and to sensitive data. Think about how their activities will be monitored. Will one be able to ensure that all access to data can be restricted once a certain project has been completed?

Once the decision to offshore has been made the next step would be to deliberate what type of work would be safe to outsource.
Generally, in legal outsourcing, besides transcription, secretarial support, voice messaging and word processing, procedures that are normally carried out by legal assistants, paralegals, and professional support lawyers are the ones outsourced/offshored.
Any work involving sensitive customer information such as tax returns, Social Security numbers and medical records should not be made easily accessible. Bear in mind that data theft can be easily committed in many countries and there is very little scope for prosecution.
And coming back to the question of financial benefits remember that ensuring all this security adds to the cost of outsourcing/offshoring your projects.
