Proofpoint explores acquisition of data security specialist Varonis

Cybersecurity firm Proofpoint is reportedly exploring a potential acquisition of data security specialist Varonis, according to a Reuters report citing an insider source. Varonis, a Miami-based company valued at around $5 billion, experienced a more than 10% increase in its Nasdaq-listed stock price following the news. Varonis specializes in cybersecurity services, including data classification for cloud storage systems and monitoring employee behavior. The company employs over 2,400 individuals in 14 offices globally.

In June, Varonis had reportedly considered a sale after attracting private equity interest, which had driven its shares up by approximately 30%. A prospective deal between Proofpoint and Varonis would unite two entities in the data security sector. Proofpoint's offerings are centered around assisting companies in safeguarding against cyberattacks, while Varonis provides a variety of security and governance technologies, such as AI-native data security solutions and protection against AI-powered threats.

Thoma Bravo, a private equity firm, acquired Proofpoint in 2021 for approximately $12.3 billion in a buyout transaction. The combination of Proofpoint and Varonis is believed to potentially enhance the former's capabilities in securing sensitive corporate data and managing access to it. In February 2026, Proofpoint and Concentrix entered into a partnership to deliver cybersecurity services across the Asia Pacific region.

Under this arrangement, Concentrix integrated Proofpoint's security solutions into its Security Operations Centre services, aiming to assist organizations in protecting their personnel, data, and digital communications.
