Who develops and maintains NullPort?
NullPort is designed, developed, and maintained by JBM Computech (https://jbmcomputech.com).
What industries and equipment does NullPort support?
NullPort is engineered for enterprise applications across:
- Industrial Automation & OT/SCADA: PLCs (Siemens, Rockwell Allen-Bradley, Schneider Electric, Mitsubishi, Omron), Modbus RTU/TCP, PROFINET, PROFIBUS, EtherCAT, and robotics.
- Automotive & Transportation: ECUs, CAN 2.0A/B, CAN FD, LIN, FlexRay, Automotive Ethernet, UDS ISO 14229, DoIP ISO 13400, and SAE J2534 PassThru.
- Medical & Healthcare Technology: Diagnostic laboratory analyzers, patient telemetry, and imaging peripherals inside sterile cleanrooms (ISO 13485 / IEC 62304).
- Enterprise IT Infrastructure: Out-of-band server consoles, BMC/IPMI, enterprise HSMs, YubiKey authentication tokens, CAD licensing dongles, and SAN fabrics.
- Test & Measurement: Oscilloscopes, Spectrum Analyzers, VNAs, and programmable DC power supplies via USBTMC, VISA, SCPI, and GPIB.
- IoT & Silicon Bring-Up: High-performance SoCs, FPGAs (Xilinx, Intel), JTAG/SWD debuggers (J-Link, ST-LINK), and low-level physical buses.
Is NullPort only for USB over internet sharing?
No. While NullPort delivers high-performance USB 2.0/3.0/3.1 sharing over WAN, it is a comprehensive multi-protocol physical hardware virtualization platform. It virtualizes industrial fieldbuses, automotive networks, low-level buses (JTAG, SWD, UART, I2C, SPI, CAN, PCIe), IT infrastructure consoles, Mesh Layer 2/3 VPN, 60 FPS remote screen control, encrypted team messaging, audio/video conferencing, and compliance audit reports.
Do I need inbound port forwarding or a local network (LAN)?
No. NullPort operates strictly over the public WAN and requires zero router configuration, port forwarding, or local network (LAN) presence. Traffic routes securely across the public internet with automated dynamic 8 MB/s P2P shift for maximum efficiency.
What is NullPort Workspace?
NullPort Workspace (https://workspace.nullx.in) is an integrated engineering collaboration suite offering encrypted direct and channel messaging, low-latency HD audio/video calls, 60 FPS remote screen control with keyboard/mouse injection, and resumable file transfer.
What enterprise quota and governance features are available?
NullPort provides multi-tenant organization governance, role-based access control (RBAC), SSO, dynamic quotas (concurrent devices, daily streaming minutes, chat volume, file transfer caps), and downloadable tamper-evident audit reports in PDF and CSV format.
Can I share webcams or USB audio?
Yes. NullPort supports isochronous USB device traffic used by high-resolution webcams and USB audio interfaces over WAN.
What platforms are supported?
NullPort provides native standalone portable applications for Windows (10/11), Linux (Ubuntu, Debian, Fedora, Arch), macOS (Apple Silicon & Intel), Android 12+, and Raspberry Pi / SBCs (AArch64, ARMv7).
Does the free trial start at registration?
No. The 30-day enterprise evaluation trial begins when you create your first sharing invitation.
