The story
History
In 1991, brothers Sreekanth Ravi and Sudhakar Ravi founded the company under the name Sonic Systems to develop Ethernet and Fast Ethernet cards, hubs and bridges for the Apple market.
In the late 1990s, the company released a security product initially called Interpol and later branded SonicWALL, a dedicated hardware appliance with firewall and VPN software intended for the small-business market. As sales for security appliances rapidly accelerated, the company exited the Apple add-on networking business and refocused exclusively as a network security company.
In late 1999, the company changed its name from Sonic Systems to SonicWALL, Inc. to represent the shift to network security, and in November 1999 SonicWall went public on the Nasdaq with the symbol SNWL.
In 2001, SonicWall upgraded its Global Management System (GMS) software to manage more VPN devices.
Matthew T. Medeiros (formerly of Philips Components) became CEO in March 2003. SonicWall has acquired several companies during its existence, often expanding its product line in the process. In 2005, SonicWall acquired enKoo and Lasso Logic, and in 2007 acquired Aventail Corporation.
On July 23, 2010, SonicWall completed its merger with affiliates of an investor group led by Thoma Bravo, which included the Ontario Teachers' Pension Plan, through its private investor department, Teachers' Private Capital. After the merger, SonicWall was delisted from Nasdaq.
On March 13, 2012, Dell signed a definitive agreement to acquire SonicWall.
On May 20, 2016, Dell sold Dell Software, which included SonicWall, to private equity firms Francisco Partners and Elliott Management.

On January 22, 2021, SonicWall said it was attacked by "highly sophisticated threat actors" in a potential zero-day attack on certain SonicWall secure remote access products. On January 25, former lulzsec hacker Darren Martyn announced exploits against old VPN vulnerabilities. These exploits and the January 2021 attack were unrelated; SonicWall confirmed that the Martyn exploits were patched in 2015.
On January 7, 2022, SonicWall said that some of its email security and firewall products were hit by the Y2k22 bug, and released patches after a few days.
On July 21, 2022, former president and CEO Bill Conner took on the role of Executive Chairman of the Board. Former SonicWall Chief Revenue Officer Bob VanKirk was named president and CEO.
2026 zero-day vulnerabilities
In July 2026, SonicWall disclosed that attackers had exploited zero-day vulnerabilities in its SMA1000 remote-access appliances. The attackers deployed custom KnuckleBall malware and related tools, dating back to June 22nd. In response, SonicWall issued fixes and CISA added both flaws to its public warning list. In August, researchers reported that several groups continued targeting vulnerable appliances, with the INC ransomware group responsible for most of the recent activity.
