plug-ins and community-contributed features, Caldera supports a range of use cases
including adversary emulation, purple teaming, detection engineering, and continuous
security validation. Using Caldera, defenders can emulate known threat actor behavior
and perform other red team activity to evaluate their organization’s defensive
capabilities, test analytics, and find detection gaps. As a modular tool based on the
MITRE ATT&CK framework, Caldera is designed to be extensible, intelligence-driven,
and automation-friendly.

Texera
Texera is an open-source system to support collaborative data science, AI, and
ML using GUI-based workflows. Our vision is to develop a system to support cloud
platforms on which users can easily analyze data and use AI/ML techniques provided as
operators. Users with various backgrounds, irrespective of whether they know coding or
not, can collaborate on the same project to construct a pipeline. Experienced users can
use programming languages such as Python, R, Java, and Scala to implement customized
computation logic. The platform allows users to pause the execution of a workflow to
investigate the operator states, and resume the execution at a later time. The platform
can be used by a research community to publish valuable resources such as data sets,
workflows, and ML models to share their domain-specific knowledge and support
reproducibility of scientific research. The platform also allows users to elastically
request computing resources from public clouds for computationally-intensive tasks.
