How does ASA ACL logic translate to FortiGate policies?

ASA access-list entries are converted to FortiGate firewall policies with proper source/destination addressing, service objects, and action mapping (permit/deny to accept/deny).

Are Cisco ASA service objects compatible with FortiGate?

ASA service objects and service groups are translated to FortiGate custom services and service groups, preserving TCP/UDP port ranges and protocol specifications.

What about ASA failover configs in the migration?

ASA failover and HA configurations are analyzed and recommendations are provided for equivalent FortiGate HA (active-passive or active-active) setup, though HA requires target-side configuration.

The Challenge of ASA to FortiGate Migration

ACL to Policy Translation

Cisco ASA extended ACLs must be converted to FortiGate's firewall policies with interface-pair based matching.

NAT to VIP Conversion

ASA object NAT and twice NAT rules need to be converted to FortiGate VIP objects and IP pools.

Object-Group Migration

Network objects, service objects, and object-groups must be converted to FortiGate address and service objects.

Security Level Mapping

ASA's interface security levels don't exist in FortiGate - policies must explicitly define srcintf/dstintf.

How NetConverter Solves It

Vendor-Neutral Translation

Our comprehensive multi-step pipeline normalizes configurations to a unified format, enabling accurate translation between any vendor pair.

Intelligent Policy Generation

ACLs are converted to FortiGate policies with proper interface assignments based on security analysis.

Automated VIP Creation

NAT rules are converted to VIP objects with correct external/mapped IP and port configurations.

Complete Object Migration

All network objects, service objects, and groups are converted with naming preserved.

Interface Mapping

Security level based rules are translated to explicit interface-pair policies.

4-Tier Validation System

Every translation undergoes comprehensive validation: syntax correctness, semantic accuracy, vendor best practices compliance, and AI-assisted review.

Confidence Scoring

Each conversion includes a confidence score indicating translation quality, helping you prioritize review efforts and ensuring production readiness.

Why Teams Choose This Over FortiConverter-Only Flows

Broader conversion program support

FortiConverter is aligned to Fortinet destination workflows, while NetConverter supports broader migration initiatives and multi-vendor planning.

Validation-first output review

Converted objects and policies are validated before downstream execution so teams can identify risky gaps early.

Reusable process for repeat migrations

Standardize ASA to FortiGate translation runs across many configs without rebuilding the workflow for each project.
