Firewall Migration Tool Comparison

Every vendor offers a migration utility, but most only convert to their own platform and leave validation risk to your team. Here is how NetConverter compares to vendor tools for real ASA, Palo Alto, Fortinet, and FMC migrations.

The Vendor Tool Problem

Free or paid, every vendor tool locks you into a single destination and leaves validation to you.

Cisco Firewall Migration Tool

Free desktop app -- FMC/FTD destination only
  • ✗ Outbound ACLs silently dropped during migration
  • ✗ VPN tunnels not migrated (no detection, no warning)
  • ✗ BGP routing not detected or converted
  • ✗ L7 and IPS policies must be manually rebuilt
  • ✗ Nested service groups flattened or lost
  • ✗ Multi-sequence route-maps not supported
  • ! 35+ bugs fixed in version 10.0 alone

Palo Alto Expedition

Free VM -- EOL'd December 2024, PAN-OS destination only
  • ✗ Roughly 50-60% accuracy on real-world configs
  • ✗ No App-ID mapping from source config
  • ✗ Dynamic routing not supported
  • ✗ VPN migration unreliable or broken
  • ! No replacement -- PA recommends paid Professional Services
SECURITY: 11 CVEs disclosed (CVSS up to 9.9). Unauthenticated remote code execution, cleartext credential storage, and CISA-confirmed active exploitation. Expedition should not be deployed in any environment.

Fortinet FortiConverter

Paid annual license -- FortiGate destination only
  • ✗ Twice-NAT creates 2-3x policy explosion
  • ✗ Wildcard masks misinterpreted or skipped
  • ✗ SNORT/IPS rules not converted
  • ✗ Complex object groups require manual rework
  • ! Fortinet's own docs call it "a starting point, not a solution"

Apples to apples with Expedition

Scored against Expedition’s own vendor matrix and four API use cases — not a NetConverter feature list. Cells are Live, Preview (code exists, not a productized path), or Missing. Updated 2026-09-01.

Vendor objects → PAN-OS

Expedition’s destination is always PAN-OS. We score local ingest and server emit separately.

Expedition cell Expedition NC Local ingest NC Server → PAN-OS Honest score
Check Point R80+ objects, security, NAT Live Live (collector + handoff) Live (CP→PA jobs) Live — zones still any; NAT placeholders
Check Point L3 + static routes Live Live (Gaia) Live Live
Check Point R75/R77 Live Missing — Wont — we are R80+ Management API
Check Point VPN Empty in their matrix Membership only Missing Missing
Cisco ASA objects, security, NAT, L3, routes Live (8.2–9.6) Live Live Live
Cisco ASA VPN Live (their only VPN tick) Preview Not measured Preview — not claimed as translated
FirePower (ASA syntax only) Live Real FMC REST — we beat this Preview Ingest Live · emit Preview
FortiGate 4/5/6 Live FortiManager 1.3.0 — newer than theirs Preview Ingest Live · Forti→PA Preview
Juniper ScreenOS / Junos 11–12 Live Missing Missing Wont — not a product path
Panorama as source Upload to a project Live --running-config Local submits /external/v1/jobs (DG-scoped) Collect Live · convert Preview until server deploy

Their four documented workflows

Expedition use case Expedition NetConverter today
3rd-party vendor config → PAN-OS Live Live for Check Point R80+ (handoff), Cisco ASA, FortiGate, and Juniper JunOS. FMC and SCM are destinations, not sources.
Remove unused objects + export XML Live (filter → delete collection) Preview — we detect unused on CP/Panorama; we do not yet delete and emit loadable XML
Bulk apply Security Profile Group Live Missing
List rules containing a subnet Live Preview — graph can; no one-click filter yet

Where we already beat the VM

Two Approaches

The difference between converting and hoping vs. converting and proving.

Traditional approach

Convert and Hope

Legacy tools perform a single-pass conversion, then leave you to manually verify every object, rule, and reference before deployment.

  1. 1 Single-pass conversion
  2. 2 Manual review of all output
  3. 3 Deploy to staging
  4. 4 Discover errors in production
NetConverter approach

Validate at Every Stage

A multi-stage validation pipeline checks objects, features, references, and vendor rules independently — catching errors before they reach your network.

  1. 1 Parse and extract to vendor-neutral format
  2. 2 Validate data completeness and feature coverage
  3. 3 Serialize with AI-enhanced mapping
  4. 4 Validate output integrity and vendor compliance
  5. 5 Auto-correct and deploy with confidence

Optimization & App-ID Adoption

Every major firewall vendor offers some form of policy optimization. Most are limited to a single platform, require live traffic data, and focus on one problem at a time. Here is how the landscape looks today.

Industry Standard Approach

Gradual, Traffic-Dependent

The standard App-ID adoption workflow — whether using Palo Alto's built-in Policy Optimizer, vendor professional services tools, or third-party scripts — follows a well-documented pattern: clone port-based rules with App-ID additions above the originals, then observe traffic over weeks before removing the legacy rules.

  1. 1 Identify port-based rules eligible for App-ID migration
  2. 2 Clone rules with applications added, positioned above originals as a safety net
  3. 3 Commit and push to managed devices
  4. 4 Monitor traffic over weeks to confirm App-ID rules absorb all traffic
  5. 5 Remove legacy port-based rules once hitcounts reach zero
Inherent constraint: This approach requires production traffic data to drive decisions. New rules, low-traffic rules, or lab environments get no recommendations. Palo Alto's own documentation recommends migrating "a few rules at a time" with gradual validation — a process that can span months for large rulebases.
NetConverter Approach

Intelligent Assessment in Minutes

Rather than waiting for traffic to tell you which App-IDs to use, NetConverter analyzes your configuration against a comprehensive knowledge base of port-to-application mappings — delivering per-rule recommendations with confidence scoring before any changes are made.

  1. 1 Connect to Panorama or upload XML config
  2. 2 Full analysis runs automatically — App-ID, unused objects, shadows, posture
  3. 3 Review scored recommendations with confidence and risk levels
  4. 4 Export actionable remediation plan (Excel, YAML, text)
  5. 5 Execute reviewed changes on your schedule, with full control
Key advantage: Knowledge-backed recommendations work from configuration alone — no traffic dependency, no waiting period. Get a complete optimization assessment in one session, then use the standard clone-and-validate approach for implementation with confidence.

Optimization Scope Comparison

Built-in tools and vendor scripts focus on App-ID migration. NetConverter covers the full optimization landscape.

Capability Policy Optimizer & Vendor Scripts NetConverter
Primary purpose App-ID adoption (single focus) Full optimization + App-ID + posture
Assessment speed Requires days-weeks of traffic data collection Complete analysis in under 2 minutes
App-ID intelligence Based on observed traffic patterns Knowledge-backed, works without traffic data
Confidence scoring Application count and hitcount data Per-rule confidence % with risk classification
Unused object detection Not included Full hierarchy-aware scanning
Shadow rule detection Not included Multi-criteria analysis
Security posture audit Not included Disabled rules, any-any, missing profiles
Duplicate detection Not included Cross-device-group consolidation
Report exports In-product views only Excel (14 sheets), YAML, JSON, text
Platforms PAN-OS / Panorama only Panorama, FMC, Strata Cloud Manager
Pre-change risk Requires changes on production device Read-only analysis — zero production risk
Works with Existing traffic patterns only Any config — lab, pre-production, or live

Note: NetConverter complements the standard App-ID adoption workflow. Use NetConverter for rapid assessment and prioritization, then follow your preferred implementation approach — whether that's Policy Optimizer, professional services, or manual execution — with confidence in which rules to migrate first.

The Vendor Optimization Landscape

Each vendor provides built-in tools for their own platform. Third-party solutions offer cross-vendor coverage at enterprise price points. NetConverter bridges the gap with multi-vendor optimization at an accessible cost.

Capability PA Policy Optimizer Cisco CDO Analyzer FortiManager Tufin / AlgoSec NetConverter
Platforms covered PAN-OS only FMC / FTD only FortiGate only Multi-vendor Panorama, FMC, SCM
Cost Included with PAN-OS Requires CDO license Included with FortiManager Enterprise license Per-analysis pricing
App-ID / App migration Yes (traffic-based) No equivalent No equivalent Partial Knowledge-backed
Unused object detection No Via community scripts Yes (date filter) Yes Yes (hierarchy-aware)
Shadow rule detection No Yes No Yes Yes (multi-criteria)
Duplicate rule detection No Yes No Yes Yes (cross-DG)
Security posture audit No Expired rules only No Yes Yes (profiles, logging, any-any)
Works without traffic data No — requires production traffic Yes Partial Yes Yes — config analysis only
Export / remediation plan In-product only Recommendations only No export Reports + workflows Excel, YAML, JSON, text
Deployment model Built into firewall Cloud service (CDO) Built into FortiManager On-prem or SaaS SaaS — no install

Current coverage: Palo Alto Panorama optimization is generally available. Cisco FMC and Palo Alto Strata Cloud Manager optimization are available as read-only analysis workflows — NetConverter reports findings and recommendations, it does not push changes to your management platform. Fortinet FortiManager is coming soon. Our goal is a single tool that analyses every vendor you manage — without needing a separate license, subscription, or workflow for each platform.
