A FireMon alternative focused on the whole network, not just rule hygiene.
FireMon specializes in firewall rule analysis: usage scoring, cleanup recommendations, and risk assessment. SAMURAI works one level up — it shows you the whole multi-vendor estate: security policies, NAT, objects, and VPNs across Palo Alto, FortiGate, and Cisco FMC, with every configuration change detected and attributed to its admin, plus the routers, switches, ACI fabrics, ISE, and vCenter your firewalls live among. Self-hosted, air-gap friendly, deployed in minutes.
Updated June 2026
What you get instead
Multi-vendor policy visibility
Search firewall rules across Palo Alto, FortiGate, and Cisco FMC with one query language: zones, addresses, ports, actions.
Change tracking with attribution
Every policy change detected from real device state, diffed, and attributed to the admin who made it. No reliance on audit logs.
Beyond firewalls
The same dashboard covers routers, switches, Cisco ACI fabrics, ISE TrustSec, and VMware vCenter: nine device types in one view.
Path tracing with ACL evaluation
Hop-by-hop traffic simulation across the estate shows which rule permits or denies a flow at every hop.
Endpoint discovery built in
Endpoints correlated from MAC tables, ARP, DHCP snooping, CDP/LLDP, 802.1X, and an offline IEEE OUI database.
Self-hosted, air-gap friendly
One Docker container on your VM. No SaaS dependency, no telemetry, nothing leaves your perimeter.
SAMURAI vs FireMon
An honest comparison. FireMon is strong at rule-level analysis and cleanup. SAMURAI is strong at estate-wide visibility and change attribution across more than firewalls.

Firewall policy change monitoring
We'd rather be honest: if unused-rule cleanup and risk scoring are your priority, FireMon earns its price. If you need to see and search everything across a multi-vendor network, and know who changed what, when — that's what SAMURAI is built for.
Frequently asked questions
Is SAMURAI a direct FireMon replacement?
For multi-vendor policy visibility, change tracking, and audit trails: yes. For rule usage scoring and cleanup recommendations: no — FireMon remains the specialist there. If your real need is seeing the whole estate and knowing who changed what, SAMURAI is the purpose-built option.
Does SAMURAI score unused or shadowed rules?
Not today. SAMURAI shows you every rule as it actually is, with full change history and admin attribution, but it does not compute usage-based cleanup recommendations. We would rather say that plainly than oversell it. A firewall policy analyzer and optimizer is on our roadmap — built on the same multi-vendor visibility layer, because cleanup recommendations are only as good as the inventory beneath them.
FireMon vs AlgoSec vs Tufin: how does SAMURAI fit?
Those three compete on firewall policy lifecycle: optimization, recertification, workflows. SAMURAI competes from a different angle with all of them — full-stack multi-vendor visibility (firewalls plus the network around them), self-hosted, deployed with one docker run.
Can I evaluate SAMURAI without a sales process?
Yes. Request a demo and you will typically have a reply within 24 hours; deployment itself is one docker run with a free test license.
Does SAMURAI work in air-gapped environments?
Yes. It ships as a self-contained Docker image with an offline IEEE OUI database and no telemetry. Nothing leaves your perimeter.
