Airlock API

Customized protection of your interfaces

Modern applications and services shift the user guidance into the end devices of the users, as Single-Page Application (SPA) in the browser or as Smartphone App. Communication with the servers thus focuses on the exchange of process data via APIs (Application Programming Interfaces). REST/JSON APIs, in particular, are currently in vogue. The new architecture exposes them to a large extent and they require the same level of protection against web attacks. Airlock API is therefore based on Airlock WAF and comes with a solid filter arsenal for web security.

  • Mobile Security

Airlock Gateway 7.4 and Airlock Microgateway 1.0

What is the Airlock Gateway?
The Airlock Secure Access Hub contains the three products Airlock WAF, Airlock API and Airlock IAM. However, when it comes to downloading, deploying or documenting the Secure Access Hub, there are only two technical components: The Airlock Gateway and Airlock IAM. Hence, we are using the term Airlock Gateway from now on when referring to the technical component which provides the functional building blocks for Airlock WAF and the content filtering functionality of Airlock API. This mainly affects technical documentation, architecture blueprints or release announcements such as this one.

The Airlock Gateway has always been available as an appliance. With the launch of the Airlock Microgateway, it is now also available as a container.

The OWASP Top 10 API Security Risks

APIs are likely to develop, over the coming years, into the main attack surface for web applications. OWASP is responding to this with a new and specialised top ten list for API security.

Read our whitepaper "Airlock and the OWASP Top 10 for API Security 2019" and learn all about the ten biggest API security risks and how you can protect yourself against them.

Advanced API Protection

The Airlock API gateway offers a range of protective mechanisms that are tailor-made for APIs. JSON Schema and OpenAPI specifications for APIs can be uploaded and enforced via the gateway. Only API calls that meet these specifications will be forwarded to the internal APIs. Innovative functions such as dynamic value endorsement (DyVE) also enable dynamic whitelisting of permitted variables within an API interaction.

API access control

One of the main reasons for using API gateways is to ensure access control to APIs. The Airlock API gateway validates access tokens and permits role-based access authorisation for API end points. The Airlock API gateway works in conjunction with Airlock IAM to support OAuth 2.0, OpenID Connect 1.0 and SAML 2.0 in protecting access to APIs.

High availability

The Airlock API gateway is a reverse proxy with failover and load-balancing functions, efficiently ensuring high availability of connected services. When modifications are made to the application infrastructure (e.g. starting/stoping of additional instances), Airlock API automatically takes over and enables high scalability. TLS is also terminated in advance, relieving the burden on APIs and enabling simple scaling.

API monitoring, statistics and reporting

Built-in dynamic reporting provides an overview of all API access attempts at all times. Access logs for API calls can be forwarded to peripheral systems and, therefore, be used as a basis for monetisation of accesses. Interactive dashboards ensure an overview of both attempted attacks and specification violations, highlighting performance problems and displaying back-end faults.

Learn more about Reporting and SIEM integration


Thanks to its comprehensive REST API, the Airlock API gateway is easy to integrate into DevOps pipelines. The outcomes of service events in a microservice architecture environment can be tracked automatically via the API gateway. For example, a service update can automatically deploy the new OpenAPI specification to the API gateway.
