New Report: The Digital Footprints of Many Executives Can Leave Their Companies Seriously Exposed

Senior leaders are visible by design. They speak at events, post on LinkedIn, sit on boards, and sign public filings. That visibility builds brands and drives growth. It also creates risk. In our latest Rapid7 Labs report, Executives’ Digital Footprints: The Overlooked Corporate Vulnerability , w...

How Exposed Endpoints Increase Risk Across LLM Infrastructure

As more organizations run their own Large Language Models LLMs, they are also deploying more internal services and Application Programming Interfaces APIs to support those models. Modern security risks are being introduced less from the models themselves and more from the infrastructure that...
