Batfish vs FireMon
Both stand on network security policy management software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose Batfish if you need configuration-based checks for policy, security, change impact, or network resilience. Teams working with Aruba, Dell Force10, or Foundry should account for the project's limited support for those platforms.

Choose FireMon if your organization needs to manage security policy across complex, multi-vendor environments and wants policy visibility, governance, and change control. Look elsewhere if you need a free plan or a published Security Manager price; pricing depends on the deployment and support configuration.
