# Frequently Asked Questions

## What is SAMURAI Networks?

SAMURAI Networks is self-hosted, multi-vendor network security monitoring and
management software: a single pane of glass that continuously syncs configuration
and state from Cisco, Palo Alto, FortiGate, Juniper SRX, VMware and Active
Directory, discovers endpoints, traces traffic paths, detects changes, and
analyzes firewall policy. See the [Introduction](https://docs.nometa.az/md/v4.8.0/introduction.md) for the
full overview and the [Firewall Analyzer](https://docs.nometa.az/md/v4.8.0/firewall-analyzer.md) for the
policy-analysis side.

## What are the default login credentials?

The default login is `admin` / `admin`. Change it immediately after the first
sign-in; the UI prompts you to do so.

## Does SAMURAI Networks make changes to my devices?

No. It is agentless and read-only: every platform is connected with a read-only,
least-privilege account over its native API or SSH, and SSH device commands are
restricted to `show`. SAMURAI Networks polls and reads; it never writes
configuration. See [Device Onboarding](https://docs.nometa.az/md/v4.8.0/device-onboarding.md) for the
per-vendor account requirements.

## How is SAMURAI Networks licensed?

SAMURAI Networks is license-gated. [Get a free trial
license](https://share.exploit.az/go/free-trial-lic) and upload it under
**Settings → License** after signing in. The License page shows customer,
validity, per-type device limits and current usage; see
[Deployment](https://docs.nometa.az/md/v4.8.0/deployment.md#licensing) for how verification works.

## Can I use my own MongoDB?

Yes. The image is external-first, embedded-fallback: set `MONGODB_URL` to use your
external MongoDB, and if it is unset or unreachable the embedded `mongod` is used
instead. Mount a volume at `/app/mongo-data` to persist the embedded database. See
[Deployment](https://docs.nometa.az/md/v4.8.0/deployment.md) and
[Database Redundancy](https://docs.nometa.az/md/v4.8.0/database-redundancy.md) for the high-availability
options.

## Which vendors does SAMURAI Networks support?

Cisco ACI (APIC), Nexus Dashboard Orchestrator, FMC, FTD/ASA, ISE, and IOS /
IOS-XE / NX-OS / IOS-XR routers and switches; Palo Alto, Fortinet FortiGate and
Juniper SRX firewalls; Junos and VyOS routers; VMware vCenter; and Microsoft
Active Directory. The [Device Panels](https://docs.nometa.az/md/v4.8.0/device-panels.md) pages show what each
platform exposes.

## How are device credentials stored?

Device passwords, SMTP/LDAP secrets and tokens are encrypted at rest with
AES-256-GCM. TLS verification is handled per connector.
