View company profile

We are SonicWall, a cybersecurity forerunner with over 30 years of expertise. Our journey began in 1991 when brothers Sreekanth Ravi and Sudhakar Ravi founded our company as Sonic Systems, initially focused on developing Ethernet and Fast Ethernet cards, hubs, and bridges for the Apple market. However, recognizing the burgeoning need for robust internet security, we pivoted in the late 1990s, launching our first security appliance. This marked a significant turning point, leading us to rebrand as SonicWALL, Inc. in 1999 and dedicate ourselves exclusively to network security. Our original mission was to provide companies with technology that is as affordable as it is effective, a principle that continues to guide us today.

At SonicWall, we're passionate about safeguarding organizations as they navigate the complexities of the hyper-distributed era. In a world where workforces are increasingly remote, mobile, and cloud-enabled, we deliver seamless protection against the most evasive cyberattacks across boundless exposure points. We empower businesses of all sizes – from small and medium-sized businesses (SMBs) to large enterprises and government agencies – to secure their vital infrastructure and data. Our comprehensive portfolio includes next-generation firewalls (NGFW), unified threat management (UTM), virtual private networks (VPNs), secure SD-WAN, cloud security, email security, endpoint security, and more. We pride ourselves on knowing the unknown, providing real-time visibility, and enabling breakthrough economics to close the cybersecurity business gap. With a global presence and a dedicated team of over 1,600 employees across 37 countries, we continue to innovate and evolve, ensuring our partners and their customers are never alone in the fight against cybercrime.
