PSG, a growth equity firm, led a $45m Series B round in MixMode, a provider of self-learning solutions to detect cyberattacks, with participation from Entrada Ventures. “As successful cyberattacks have accelerated in both number and scale, there is a growing acceptance that legacy cybersecurity platforms are missing the majority of attacks. MixMode helps organizations understand and address the full scope of their risks as their data volume continues to expand. We are fortunate to be working with PSG and we are aligned on the size of this opportunity. We are in the first inning of a transformation from rules-based security programs to true self-learning security programs," John Keister, MixMode CEO.
