Background Verification Of Employees After Joining

Hi,
My company wants to conduct employee verification of employees. Till date it has not been practiced here, however, as many of the employees are on client site (India), and no such verification has been done yet so we have decided to do it for all employees, even who are working here for more than 2 years. Pl suggest me any formal mail to circulate among employees.

Hello Stuti,
Good day to you and your team.
My name is Hardeep Singh and I work with InstaVeritas. We are a pan India background verification firm providing pre and post-employment verification solutions. We are a technology driven background screening firm and have developed a highly sophisticated and quick process with high deliverability thus redefining the manner in which companies conduct background checks.
Why screen your prospective candidate?
We live in a world where the threats and risks originating from employees and other personnel associated with a firm is on a high and rising. The best way to handle such a risk is to mitigate such a risk. Background checks help us do exactly just that. While the benefits of background checks are countless, the major ones include protection against the cost incurred and the emotional anguish caused with a bad hire, and also helps mitigate compliance from an audit point of view. Through background checks, we can sieve out all information on a prospective candidate; their background, their academia and professional history, helping you to make an affirmed decision about a candidate.
About InstaVeritas:
We currently work with over 200 companies including some of the country's largest and fastest growing companies - Infosys, OLA Cabs, GMR Group, Apollo Hospitals and Sequoia to name a few.
