About Rhombus Systems

Rhombus is a cutting-edge startup specializing in physical security solutions, catering to a diverse range of clients including school districts, cities, and Fortune 500 companies. The company operates in the physical security market, providing advanced security cameras and sensors that are managed through a unified cloud-based platform.

Rhombus's business model revolves around offering a comprehensive security solution that integrates hardware (cameras and sensors) with software (cloud management and AI processing). This combination allows clients to see, manage, and respond to security threats in real time. The company generates revenue through the sale of its security hardware, subscription fees for its cloud services, and additional services like 24/7 alarm monitoring.

One of the standout features of Rhombus's offering is its proactive alert system. This system uses edge-based AI processing to detect unwanted behavior, audio, and environmental triggers, providing real-time alerts to improve security response times. The platform is designed for infinite scalability, allowing clients to manage unlimited devices, locations, and users from a single console. This makes it easy to deploy and manage security solutions across multiple sites globally.

Rhombus also emphasizes ease of use and security. The platform is built on a zero-trust infrastructure, meaning it assumes no part of the system is secure and continuously verifies the security of each component. Regular penetration testing and automatic updates ensure the system remains secure and reliable. Additionally, the company offers integrated alarm monitoring with Five Diamond Certified agents, ensuring faster and verified responses to emergencies.

The platform's open API integrations allow clients to streamline workflows and enhance visibility by connecting with other industry-leading solutions like Envoy and Lumeo. This flexibility makes Rhombus a versatile choice for organizations looking to enhance their physical security infrastructure.
