A former security adviser at the IT monitoring and network management company SolarWinds Corp. said he warned management of cybersecurity risks and laid out a plan to improve it that was ultimately ignored.

In a 23-page PowerPoint presentation reviewed by Bloomberg News, Ian Thornton-Trump recommended to company executives in 2017 that SolarWinds appoint a senior director of cybersecurity, and said he told them that ¡°the survival of the company depends on an internal commitment to security.¡±

The following month, he terminated his relationship with the company, saying he believed its leadership wasn¡¯t interested in making changes that would have ¡°meaningful impact.¡±
