SonicWall's 2026 Professional Services Protect Brief reveals that professional services firms, including law firms and managed service providers, experienced 3 billion IPS events in the first half of 2026, marking the highest attack volume across tracked industries. The report indicates that 460 organizations in this sector are actively detecting ransomware campaigns, emphasizing the unique vulnerability of client data due to accessible systems like client portals and document management platforms. Attackers exploit these vulnerabilities, targeting sensitive data such as legal records and financial transactions. The report highlights that breaches involving managed service providers (MSPs) can compromise multiple client networks simultaneously. Notably, ransomware families like Ryuk and Sodinokibi are specifically targeting these firms due to their access to critical data. SonicWall's findings are based on data from over one million security sensors globally, documenting attack patterns and exploitation vectors prevalent in the professional services landscape.
