What is Nexus IQ?
Hereof, what is Nexus IQ used for?
Nexus IQ provides intelligence on open source components used within your applications, as well as the associated metadata, such as security vulnerabilities and licenses.
Similarly, what is Nexus lifecycle?
It is called Nexus Lifecycle and is Sonatype's new addition to their Nexus suite that scans application binaries for known vulnerabilities in open source libraries. This is where you setup your customizable policies which will decide which open source libraries are acceptable by the organization and which ones are not.
Open source projects can qualify for a free Professional license, or they can take advantage of free Nexus Professional hosting on http://oss.sonatype.org. Sonatype is very committed to supporting the development of quality open source and this is our way of giving back to the community.
