CriticalBlue, operating under the brand name Approov, is a cybersecurity startup that specializes in protecting Application Programming Interfaces (APIs) used by mobile apps. APIs are the software intermediaries that allow different applications to communicate with each other. CriticalBlue's primary product, Approov API Threat Protection, ensures that only legitimate instances of a mobile app can access backend servers, thereby preventing unauthorized access and fraud.

The company serves a diverse range of clients, including businesses in the financial services, healthcare, and e-commerce sectors. These industries are particularly vulnerable to API abuse and fraud, making them ideal customers for CriticalBlue's solutions. The market for API security is growing rapidly as more businesses rely on mobile apps to interact with their customers and manage their operations.

CriticalBlue operates on a subscription-based business model. Clients pay a recurring fee to use the Approov service, which includes features like mobile app authentication, threat detection, and API security. The company also offers integration with popular API gateways like Kong, making it easier for businesses to deploy their security measures without modifying their existing API code.

Revenue is generated through these subscription fees, and the company may also offer premium features or custom solutions for larger enterprises. The scalability, redundancy, and resilience of the Approov cloud service make it a reliable choice for businesses looking to secure their mobile app APIs.

In summary, CriticalBlue provides a crucial service in the cybersecurity landscape, focusing on API threat protection for mobile apps. Their solutions are easy to integrate, scalable, and designed to meet the needs of various industries.
