Access-Segmented VPN
Tentrait’s VPN solution is built for modern OT/IT environments where **least-privilege access** and **operational continuity** matter.
What It Does
- Grant VPN access per user, per device, or per vendor group
- Restrict access to **specific IPs, subnets, or ports**
- Real-time logging and **identity-level audit trails**
- Multi-site deployments via Meraki, Azure, or site-to-site tunnels
- Optional time-restricted or one-time-use credentials
Use Cases
Third-Party Vendor Access
Grant a contractor access to only one PLC on port 502, without exposing other assets.
Departmental Segmentation
Allow your OT engineering team access to HMI systems, while finance is restricted to ERP APIs.
Per-Site Isolation
Users can be locked to one manufacturing site, even across shared VPN infrastructure.
Audit + Compliance
Detailed logs help you prove access boundaries for ISO 27001 or NIS2 compliance.
Zero Trust, Minimal Disruption
Unlike traditional VPNs that grant full internal access, Tentrait’s approach aligns with Zero Trust principles and operational constraints — with no need to rip and replace your existing systems.
