LTTS is the engineering services arm of the L&T Group—one of India’s largest conglomerates with business interests across construction, financial services, manufacturing, engineering, and technology. With around 17,000 employees, some of whom live in shared residences, known as “Paying Guests” in India, juggling between enabling everyone to work remotely and security of the organization’s network and data was a major challenge the company had to face.
The first step to a secure working environment meant connecting the VPN with Azure AD and enable multi-factor authentication for people. LTTS began using Microsoft Identity Manager to enforce conditional access to sensitive documents and data. Microsoft 365 E5 security structure was used to continuously monitor the organization’s security scores and fix problems preemptively.
With the majority of work being done on SaaS applications or applications opened on the internet, LTTS ensured all these apps were integrated with Azure AD, thereby giving them the advantage of enforcing conditional access. Microsoft App Proxy was extensively used and it became the primary gateway for employees to open applications on the internet.
To enable the seamless shift to hybrid work, LTTS also relied on Microsoft Teams for collaboration between different teams such as delivery, sales, IT, quality, and human resources. In order to better manage devices in different locations, LTTS implemented Hybrid Join through Azure AD, which truly enabled the hybrid work model.
