Dear Shweta,
Any establishment in the IT and ITES sector would come under the State Shops and Establishments Act. Since the no of employees in your establishment is more than 10, the Maternity Benefit Act,1961 is applicable to it as per sec.2(1)(b) of the Act. In the absence of coverage of your establishment or any of the female employees under the Employees State Insurance Act,1948, you have to extend the maternity benefits contemplated under the MBA,1961 to such employees whenever the occasion arises.
