Like a lot of people, your mobile phone number is probably easily accessible to anyone with a bit of searching. Imagine if someone could take this number and your name and gain access to your mobile phone account including billing, email address and phone IMSI. Or maybe someone hacked into one of your social accounts and accessed your contact information and all your photos? These very real scenarios at [T-Mobile]() and [Instagram]() both occurred because of application programming interface (API) security vulnerabilities. To [learn more about the use of APIs](), Imperva commissioned [_One Poll_]() to study the attitudes of 250 IT managers security professionals. APIs power the interactive digital experiences users love and are fundamental to an organization’s digital transformation. However, they also provide a window into an application that presents a growing cybersecurity risk. Hackers like APIs because they present multiple avenues to access a company’s data and can be used together in unintentional ways to enable new attacks that exploit web and mobile applications and IoT devices. The API security survey revealed that on average companies manage 363 different APIs, and that two-thirds (69 percent) of organizations are exposing APIs to the public and their partners.

Asked about their main API security concern, respondents stated they are most worried about DDoS attacks and bots while 24 percent said they are most concerned about authentication enforcement.

Eighty percent of organizations use a public cloud service to protect the data behind their APIs with most people using the combination of API gateways (63.2 percent) and web application firewalls (63.2 percent).

This highlights an increased desire from many organizations for security to be built in from the very beginning of software development rather than as an after-thought.
