Batfish vs ManageEngine Firewall Analyzer

Batfish is an open-source tool for analyzing network device configurations and validating network behavior. It works from configuration files, so core analysis does not require direct access to network devices. Teams can inspect deployed configurations and check planned changes before deployment. Checks cover undefined references, MTU and AAA settings, template compliance, sensitive-service reachability and expected traffic paths. Batfish can test whether end-to-end reachability survives any single-link or single-device failure, compare current and planned reachability, assess ACL or firewall changes and evaluate functional equivalence across vendors. Pybatfish provides a Python 3 SDK, and example Jupyter notebooks are available. An all-in-one Docker container bundles Batfish and notebooks. It runs on operating systems supporting Docker. Documented support includes Arista, AWS, Azure, Cisco, Juniper, Palo Alto Networks and SONiC, while Aruba, Dell Force10 and Foundry have limited support.

ManageEngine Firewall Analyzer analyzes firewall logs and manages firewall configurations, helping network administrators examine bandwidth use and network activity. It accepts logs from firewalls, VPNs, IDS/IPS devices, and proxy servers across multiple vendors. Reports cover bandwidth, inbound and outbound traffic, VPN and protocol usage, and websites users access. The Professional and Enterprise editions add policy optimization, rule cleanup and reorder recommendations, and analysis of the impact of new rules. The product also provides real-time notifications and historical records of configuration changes. Those editions list compliance reporting for ISO, PCI-DSS, NERC-CIP, SANS, and NIST. It is deployed on premises, with Windows and Linux installers and mobile downloads for iPhone and Android. Standard and Professional each cost $395 a year and $595 a year, respectively; Enterprise costs $8,395 a year. The pricing note lists a 30-day trial. There is no free plan.
