Invariant

What it is

Invariant validates network configurations against connectivity and security rules using a cross-vendor digital twin. It builds its model from configuration files, so assessment does not require direct access to routers or switches. Teams can write policies in YAML and test network snapshots, including proposed changes before deployment, to identify policy violations and failures affecting critical flows. Scheduled scans can produce incident alerts with virtual traceroutes and virtual route-table differences. Invariant offers web and API access, plus a CLI and SDK for automation. Listed integrations include Jenkins, GitHub Actions, LibreNMS, Netmiko, Aerleon, Capirca, IPAM, and SIEM workflows. Supported vendors include Cisco, Juniper, Palo Alto, and AWS; listed protocols include BGP, OSPF, IPSec, NAT, policy-based routing, VPN, ACL, and VLAN. The Basic account is free with effectively no usage limits. Higher tiers add SSO, larger device counts, and preview features.
