A self-hosted Skybox Security alternative for multi-vendor visibility.
Skybox Security bundles firewall policy management with attack-surface and vulnerability modeling. Teams looking past it usually want something narrower and lighter: clear visibility into firewall and network configuration across vendors, and a record of what changed. SAMURAI does exactly that, for Palo Alto, FortiGate, and Cisco FMC plus the routers, switches, ACI fabrics, ISE, and vCenter around them. Self-hosted, air-gap friendly, deployed in minutes.

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.
Whole-network scope
The same dashboard covers routers, switches, Cisco ACI fabrics, ISE TrustSec, and VMware vCenter: nine device types in one view.
Path tracing
Hop-by-hop traffic path simulation across the estate shows which rule permits or denies a flow at each hop.
Self-hosted, no telemetry
One Docker container on your VM. No SaaS dependency, no cloud model, nothing leaves your perimeter.
Evaluation in minutes
One docker run to first dashboard in about five minutes, with a free test license. No services engagement required.
How it compares to Skybox
An honest comparison. Skybox is a broad exposure-management platform: attack-surface modeling, vulnerability prioritization, and policy management. SAMURAI is focused on seeing firewall and network configuration across vendors and knowing who changed what, when.
Focus
SAMURAI
Multi-vendor configuration visibility and change tracking
Skybox Security
Attack-surface, vulnerability, and policy management suite
Scope
SAMURAI
Firewalls plus routers, switches, ACI fabrics, ISE, and vCenter in one view
Skybox Security
Network model centered on firewalls and vulnerabilities
Deployment
SAMURAI
Single self-hosted Docker container, air-gap capable, serving data in about five minutes
Skybox Security
Enterprise platform rollout
Attack-surface / vuln modeling
SAMURAI
Not our focus: no vulnerability scoring or exposure modeling
Skybox Security
Their core strength
We'd rather be honest: if you need attack-surface and vulnerability modeling, Skybox earns its scope. If you need to see and search firewall and network configuration across vendors, and know who changed what, when: that's what SAMURAI is built for.
Frequently asked questions
Is SAMURAI a direct Skybox Security replacement?
For multi-vendor configuration visibility, change tracking, and audit trails: yes. For attack-surface modeling and vulnerability prioritization: no, those are Skybox specialties. Many teams find their day-to-day need is visibility and change attribution, which is what SAMURAI does.
What are the main Skybox Security competitors?
Skybox overlaps with the firewall policy-management suites Tufin, AlgoSec, and FireMon on the policy side, and with exposure-management tools on the attack-surface side. SAMURAI competes on the visibility angle: full multi-vendor configuration search and change tracking, self-hosted and deployable in minutes.
Skybox vs Tufin: where does SAMURAI fit?
Skybox and Tufin compete on policy management and, for Skybox, attack-surface modeling. SAMURAI is the lighter, self-hosted choice when the goal is one dashboard across firewalls AND the routers, switches, ACI, ISE, and vCenter around them, with change attribution, rather than rule-optimization workflows.
Does SAMURAI run 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.
Can I evaluate it without a sales process?
Yes. A free test license ships with the Docker image (no email required), so you can point it at your own devices before talking to anyone.
