Network & AAA

TACACS+ / RADIUS identity proxy that replaces shared network credentials with per-user identity.

The Network Access Problem

Network devices — routers, switches, firewalls, load balancers — are the foundation of your infrastructure, and they’re often the least protected. Shared “admin” accounts, default credentials, and no per-user audit logging are the default in most environments. When a network device is compromised, it’s not one system that’s affected — it’s the entire network.

The problem isn’t the devices. It’s the identity model: shared credentials with no per-user accountability. PDAccess fixes this with an identity proxy that speaks the AAA protocols your network already understands.

TACACS+ / RADIUS Identity Proxy

PDAccess integrates TACACS+ and RADIUS natively, so network devices authenticate through PDAccess instead of through shared local accounts. This separates authentication, authorization, and accounting into three distinct, manageable layers — without replacing your network gear or your AAA workflows.

  • Authentication — per-user identity instead of shared admin accounts.
  • Authorization — command-level control: exactly which commands each user can run on each device.
  • Accounting — every command logged, timestamped, and attributable.

The identity proxy sits between your users and your network. Devices keep working as they always have; the identity behind the session finally changes from “admin” to a real, unique person.

Eliminate Shared Network Credentials

Shared credentials are the root of most network access risk. PDAccess removes them entirely:

  • No shared admin accounts — every engineer, contractor, and service account has a unique identity.
  • Forced MFA — multi-factor authentication is applied to network access, not just to web apps.
  • Automatic revocation — offboard someone and their network identity stops working immediately.

You no longer hand out a network password you can never fully reclaim.

Per-User Identity and MFA on Network Devices

With PDAccess, per-user identity and MFA become first-class on your network devices:

  • A junior engineer gets read-only show commands; a senior engineer can configure interfaces and routing.
  • A contractor is restricted to specific maintenance commands for a defined window.
  • Every session authenticates individually and enforces multi-factor authentication before a single command is accepted.

Role definitions and time boundaries apply the same way they do for servers, databases, and the rest of the platform.

Recorded, Audited Network Sessions

Every command executed on every device is captured into a single, audit-ready record — user, device, command, and time. PDAccess compiles this into audit trails that satisfy auditors on day one, with no manual evidence collection and no gaps in the record.

  • Full command accounting — a complete, searchable history of network actions.
  • Incident attribution — exactly who ran what, and when.
  • Compliance evidence — per-user accountability that meets PCI-DSS, SOX, and ISO 27001.

The Business Impact

Organizations using PDAccess for network & AAA achieve:

  • Eliminated shared network credentials — no more “admin” accounts known to everyone
  • Per-user accountability — every session is identified, MFA-protected, and logged
  • Command-level control — least privilege enforced on every device
  • Faster incident response — emergency access when you need it, revoked when you don’t
  • Compliance-ready — audit trails that satisfy PCI-DSS, SOX, and ISO 27001

Bottom Line

Network devices deserve the same identity, MFA, and audit controls as your servers and applications. PDAccess brings that to the network layer through a TACACS+ / RADIUS identity proxy — replacing shared credentials with per-user identity, enforcing MFA, and recording every session. The same PAM model, extended to the foundation of your infrastructure.
