Private equity firm Insight Partners led a $40m Series B round in Perimeter 81, an Israeli cloud and network security company. "With Covid-19, we witnessed an incredible surge in the demand for our services as the transition to remote work — which occurred virtually overnight — illuminated the need for companies worldwide to depart from their legacy hardware-based security and fully embrace a holistic, cloud edge network. We are thrilled that Insight Partners embraces our vision and shares our belief in the importance of forever transforming the way organizations are consuming cyber and network security," Amit Bareket Perimeter 81 CEO.
