HHD Software

What HHD Software does

HHD Software is a privately held Windows software developer founded in 1999 and operating under the trademark of Florida-based Mikom Inc. The company specializes in low-level system monitoring, diagnostic, and device-connectivity utilities for developers, QA engineers, IT administrators, and software/hardware integrators. Its product portfolio centers on a Hex Editor Neo binary file editor, three monitoring tools (Serial Monitor, USB Monitor, Network Monitor), a unified Device Monitoring Studio platform, and a Virtual Serial Port Tools suite that enables creation, sharing, redirection, and remote access of serial and USB ports across network infrastructure. Two SDK products (USB Monitoring Control, Serial Port Monitoring Control) allow third parties to embed the company's monitoring technology into their own applications under OEM/Distribution licensing.

The technology stack is Windows-native, leveraging standard Windows APIs for serial port, USB device, and network protocol inspection, with proprietary capabilities including deep inspection of 50+ network protocols, virtual serial port emulation via null-modem cables, and USB-over-TCP/IP redirection with end-to-end encryption, NAT traversal (PMP/UPnP), and integrations with VMware, Oracle VirtualBox, Microsoft Hyper-V, and Citrix XenDesktop for virtualized and remote-desktop environments. Free versions of Hex Editor Neo and Virtual USB Tools plus browser-based online tools serve as top-of-funnel adoption vehicles.

HHD Software monetizes through one-time perpetual software licenses with optional paid upgrade plans (1-5 years or Lifetime), priced between $34.99 and $374.99 per product depending on edition (Standard/Professional/Ultimate). Distribution runs through direct e-commerce on hhdsoftware.com, a three-tier reseller program offering 15-25% channel discounts, OEM/royalty-free licensing for integrators, and Windows Package Manager (WinGet) listings. Customer segmentation is horizontal, spanning SMB developers, enterprise IT, commercial/government/military users, and home/educational users across industries including aerospace, automotive, energy, and scientific research.

Revenue model

1. Software Licenses (One-time Purchase): Products are sold as one-time perpetual licenses with optional upgrade plans. Customers can purchase Lifetime Upgrades for free access to all future versions, or opt for time-limited upgrade plans (1-5 years). The 1-year upgrade plan is free with purchase.
2. Reseller Revenue: Channel partners purchase software at discounted rates (15-25% off) and resell to end customers at markup. Resellers earn commission on each sale through the tiered reseller program.
3. Free Version with Upsell: Free Virtual USB Tools is provided at no cost with no registration required. This serves as a lead generation and adoption tool, with potential conversion to paid Virtual USB Tools Pro with Client-Server licensing.
4. OEM/Distribution Licensing: Distribution/OEM License allows integration of HHD Software products into third-party applications with royalty-free distribution rights. Single Developer and Site Developer distribution licenses available for software/hardware integration.

Broad incumbents

• Microsoft Sysinternals: Microsoft's Sysinternals suite (e.g., Process Monitor, DebugView) addresses low-level Windows system monitoring. As a free, OS-vendor-bundled option, it is a structural pricing-pressure incumbent for HHD's developer monitoring tools.
• Wireshark Foundation: Wireshark is the dominant open-source network protocol analyzer. While broader in scope, it directly competes with HHD's Network Monitor for deep packet inspection and protocol debugging among developers.

Regional players

• PEAK-System Technik: PEAK-System provides CAN/serial hardware and developer tools (PCAN-View, etc.) primarily for automotive and industrial markets in Europe — an adjacent competitor for HHD's automotive and embedded engineering customer base.

Direct peers

• VirtualHere: VirtualHere is a dedicated USB-over-network solution with cross-platform support, competing directly with HHD's Virtual USB Tools in the remote USB device access use case.
• CommFront: CommFront offers serial port utilities, monitors, and USB-serial tools targeting the same developer/embedded-engineer buyer profile as HHD's monitoring and virtual serial portfolio.
• HW group: HW group's HW VSP virtual serial port and serial-over-IP products compete with HHD's Virtual Serial Port Tools, particularly for industrial and IoT customers needing remote COM port access.
• AGG Software: AGG Software publishes Serial Port Monitor, USB Analyzer, and COM port tools serving the same developer/QA engineer segments as HHD, with comparable perpetual-license pricing and Windows focus.
• Electronic Team (Eltima Software): Eltima offers USB over Ethernet, Virtual Serial Port Driver, and Serial Port Monitor — overlapping nearly head-to-head with HHD's monitoring and USB-over-IP portfolio for developers and integrators.
• Docklight: Docklight provides serial communication and scripting tools that overlap with HHD's Automated Serial Terminal and Serial Monitor for embedded engineering and test workflows.
• Fabula Tech: Fabula Tech (USB Network Gate, Serial over Ethernet) is the most direct competitor to HHD's Virtual USB Tools and Virtual Serial Port Tools. Both target USB/serial device redirection over IP with similar virtualization integrations and licensing models.
