Fortra ZTNA vs Lumeus Secure AI Infrastructure Access: Side-by-Side Comparison (2026)

Fortra ZTNA

Mid-market and enterprise teams replacing VPN will find Fortra ZTNA's strongest value in its hybrid deployment flexibility and granular access controls that actually enforce least-privilege without admin headaches. The platform covers all four critical NIST CSF 2.0 areas for identity and continuous monitoring, which matters because most ZTNA products punt on asset inventory or detection tuning. Skip this if your org needs deep integration with legacy on-premises identity systems or runs exclusively on-prem; Fortra's strength is in hybrid environments where cloud and datacenter access requirements overlap.

Lumeus Secure AI Infrastructure Access

Enterprise and mid-market security teams deploying GPU clusters need Lumeus Secure AI Infrastructure Access because it's the only platform treating AI agents as first-class subjects in access control, not afterthoughts bolted onto human IAM. The MCP Gateway logs every model interaction end-to-end while enforcing least-privilege policies across Slurm and Kubernetes schedulers, directly addressing NIST PR.AA identity controls that most vendors skip for AI workloads. Skip this if your GPU infrastructure is small or dev-only; the hybrid deployment model and identity integration work best when you're managing dozens of researchers and multiple LLM agents simultaneously.
