Application Programming Interfaces (APIs) is the life-blood of today’s app-driven world. From banks, retail and transportation to IoT, autonomous vehicles and smart cities, APIs are a critical part of modern mobile, SaaS and web applications and can be found in customer-facing, partner-facing and internal applications. By nature, APIs expose application logic and sensitive data such as Personally Identifiable Information (PII) and because of this have increasingly become a target for attackers. Without secure APIs, rapid innovation would be impossible. API Security focuses on strategies and solutions to understand and mitigate the unique vulnerabilities and security risks of APIs.
