Company context
CSPi (NASDAQ:CSPI) operates two divisions, each with unique expertise in designing and implementing technology solutions to help customers use technology to success. The High Performance Product division, including ARIA Cybersecurity Solutions, recognizes that better, stronger, more effective cybersecurity starts with a smarter approach. ARIA's solutions provide new ways for organizations to protect their most critical assets - they can shield their critical applications from cyberattack with the AZT solution, while monitoring internal traffic, device-level logs, and alert output with our ARIA ADR solution to substantially improve threat detection and surgically disrupt cyberattacks and data exfiltration. Rounding out the portfolio, Aria's AZT Gateway Software allows us to interrogate network packets at 100mbps line-rate to enforce forwarding and capture policies on the fly. Customers in a range of industries rely on our solutions to accelerate incident response, automate breach detection, and protect their most critical assets and applications - no matter where they are stored, used, or accessed.
