CHICAGO – Aug. 8, 2023 – First Analysis, a leading venture capital investor, has made a new investment in Stamus Networks, a leader in Suricata-based network security. The investment is intended to enable Stamus to advance product innovation, elevate customer experience, and scale go-to-market resources and programs. First Analysis led the $6 million Series A round of funding with participation from new investor SmoothBrain. Existing seed stage investors Elevate Ventures and VisionTech Partners also participated in the round.

This investment further cements the company’s position as an innovator in enterprise class Suricata-based threat detection and response systems that deliver effective results by integrating modern machine learning with traditional detection mechanisms from intrusion detection and network security monitoring systems. Focused on elite cyber defenders who require details, control and transparency, Stamus Networks provides a powerful alternative to other AI-based solutions.

“We are excited to partner with First Analysis and SmoothBrain and are grateful for the confidence they and our existing investors have placed in us,” said Ken Gramley, CEO of Stamus Networks.

“Some of the world’s most targeted organizations trust Stamus Networks and its network-based threat detection and response solutions to help secure their operations,” said Nick Mirchef, co-founder of SmoothBrain. “This notable list of customers includes central banks, multinational government institutions, departments of defense, managed security service providers and financial service providers.”

First Analysis has been investing in and sharing research on the cybersecurity industry for more than 30 years. This perspective was key to identifying and understanding Stamus Networks’ strong potential in network detection and response, which was the focus of First Analysis’s October 2022 Cybersecurity Quarterly Insights report.

“We were impressed by the conversations we had with the company's sophisticated enterprise customers. Each praised the comprehensive, transparent, and granular evidence delivered with detections triggered by the Stamus Security Platform,” said First Analysis Managing Director Howard Smith. “The customers also applauded the company’s customer support. We really look forward to helping scale the organization for breakout growth in this exciting market.” Howard Smith has joined the Stamus board.
