The Story of Difenda

In 2008 our CEO, Manoj Arora saw the same issue over and over again—companies misled by the cybersecurity “leaders,” technology resellers promising the impossible, and vendors overselling functionality. There was no uniformity in the cybersecurity industry and it led to poor customer experience and unsecure security processes.

With Difenda, Manoj wanted to change that dynamic and focus specifically on the customer’s outcome. Through this journey, he made an important discovery. He saw that the future of cybersecurity needed to be an integrated, connected, and collaborative experience that unified departments and provided total visibility into the people, processes, and technology that drive companies forward.

Today, Difenda is recognized as a trusted authority when it comes to Microsoft Sentinel, Defender for Endpoint, Defender for IoT, and securing customer environments leveraging the power of Microsoft.

Our exponential growth, reputation for responsiveness to our clients, and vibrant corporate culture has ensured that we stay at the top of our industry. Manoj Arora, CEO of Difenda
