Unveiling the Vectra AI Platform: Your pathway to fortified cybersecurity. Co-created with security pioneers, this innovative platform offers integrated Attack Signal Intelligence for unmatched resilience, SOC modernization, and agile response to advanced threats.

Recently, CISA released a new open-source tool named the Untitled Goose Tool that helps organizations investigate threats to Azure AD, M365 and Azure.

Last week I attended the Gartner Security and Risk Summit in London. The theme of the summit was Accelerating the Evolution of Security: Reframe and Simplify. From the very first keynote, Gartner laid down the gauntlet. "Change is needed and we must stop doing what we have always done and start learning from our mistakes." It is this very sentiment that set the tone for the show.

We at Vectra think that SOC teams need to focus on 3 challenges to stay ahead of cyberattacks. Coverage, Clarity Control

Cybersecurity authorities from the United States, New Zealand, and the United Kingdom have released a joint Cybersecurity Information Sheet (CIS) that recommends proper configuration and monitoring of PowerShell to address the recurrence of the scripting language's use in cyberattacks.
