API-Driven Subscriber Services
The telecom industry was among the first industrial sectors to embrace APIs as an enabler of digital transformation initiatives. API programs enabled telecom providers to drive internal efficiencies but also to generate new sources of revenue by delivering new value-added services to their subscribers. APIs are used to expose traditional carrier services (e.g. billing, account management and payments) but also to hook into the external API ecosystems of third-party service providers (e.g. Netflix, Disney & Apple). Securing APIs isn’t just about protecting one system — it’s about safeguarding the entire telecom ecosystem, ensuring that data flows securely and reliably across every integration.
Telecoms: A High-Value Target
Telecom providers are high-value targets for cyber attacks because their databases carry detailed information on millions of customers. A successful telecom data breach could expose contact details, dates of birth, social security numbers, driver’s license information and credit card details.
Telecom operators are the second most targeted industry for cyberattacks, after the financial sector, according to the 2022 World Economic Forum report on the Global Risks Report. The telecom industry was among the most frequently targeted industries by ransomware operators during the second quarter of 2021, according to research by McAfee Enterprise.
Mobile apps are the primary touchpoint for accessing these services and providing new business opportunities. Failure to properly secure APIs leads to system breaches, unauthorized access to private data, and ultimately loss of customers.

API Security-by-Design at Carrier Scale
Operators have invested heavily over the past decade in API management platforms to empower their global teams of developers to consume and build API-based services. Yet neither these API management platforms nor traditional application security tools are designed to automate or scale to the required levels of protection for APIs in the telecoms industry.
That is why some of the world’s largest operators, such as British Telecom (BT), Verizon and others, are using the 42Crunch API Security platform to address the unique scaling needs of telecommunications providers. Our platform enables a secure-by-design approach to API security to enable operators stay ahead of security threats — ensuring that their APIs are built with security baked in rather than treated as an afterthought. This proactive strategy is essential to protect sensitive customer data, maintain regulatory compliance, and preserve service availability. Don’t undermine the advances achieved with an API-first approach by accepting a second-class approach to security.
