Change validation: Batfish can validate planned configuration changes before deployment and deployed configurations as well.
Device access: Core analysis requires network device configurations and does not require direct access to network devices.
Security checks: Supported checks include verifying that sensitive services are reachable only from specified subnets or devices.
Failure analysis: Batfish can check whether end-to-end reachability is preserved after any single-link or single-device failure.
Change comparisons: Batfish can compare reachability across current and planned configurations and assess functional equivalence between configurations from different vendors.
Integrations: Pybatfish is a Python 3 SDK for interacting with the Batfish service, and the project also provides example Jupyter notebooks.
Operating systems: Batfish can run on any operating system that supports Docker; its containers are actively tested on Mac OS X and Ubuntu 16.04 LTS.
