A hardware keylogger is a tiny electronic device capable of capturing keystrokes from a PS/2 or USB keyboard. A keylogger contains advanced electronic circuitry for monitoring a keyboard's USB or PS/2 connection, filtering keystroke data, and recording the data to internal memory. The built-in memory typically has several megabytes (or even gigabytes), meaning it can hold years-worth of typing.

A hardware keylogger is completely undetectable for software running on the computer, such as anti-virus programs and security scanners. A hardware keylogger also requires no software or drivers, meaning the installation process can be done in a matter of seconds. Just plug the keylogger in-between the keyboard and the USB or PS/2 socket on the computer's rear side.

The KeyGrabber USB is a best-seller in the general-purpose USB keylogger segment. By entering the password the KeyGrabber USB keylogger may switch into a USB flash drive, providing instant access to the entire log file.

The KeyGrabber USB hardware keylogger is valued by customers for its compatibility with all types of USB keyboards, including wireless keyboard, Mac keyboards, and keyboards with built-in hubs. Unlike other keyloggers available on the market, the KeyGrabber USB is completely undetectable for software.

One of the newest evolvements in hardware keylogger technology are keyloggers with remote access. Keelog has created the most advanced keyloggers on the market, named the AirDrive Keylogger and AirDrive Forensic Keylogger.

The AirDrive series of keyloggers incorporates a built-in WLAN transceiver, Access Point, and TCP/IP stack, meaning you can connect to it over Wi-Fi. Once connected, you can view the data log, download it, or reconfigure the device. The more sophisticated Pro and Max versions also have the capability of sending E-mail reports with captured keystroke data to any recipient E-mail address you supply. This means you can keep track of what's happening on the monitored computer from any place throughout the world, just by checking your mailbox! The AirDrive Keylogger family also has the capability of time-stamping and live data streaming of captured keystroke data. This makes it possible to create entire networks of wireless keyloggers - a solution that is particularly recommended for monitoring several computers in a household, or controlling employee productivity in companies, or acquiring data from barcode scanners.

Software keyloggers are considered to be an alternative to hardware keyloggers. However, they inherit all the problems any other software security application would have:

• Fully detectable from OS task manager and anti-virus programs
• Operating system dependent (Mac, Windows, Linux)
• Necessity to upgrade together with operating system
• Access required in order to install (usually with administrative rights)
• Per-installation licensing
• No logging possible during computer power-up

A hardware keylogger is a clean and stealthy solution, that just always works! No drivers or software are necessary, no surprises after an operating system update. Read more here.

Keelog is the leading manufacturer of hardware keyloggers. The KeyGrabber and AirDrive series of keyloggers has sold in 100,000+ units worldwide, making it the most successful product in its class. Keelog has created the concept of a keylogger operating as a USB stick for retrieving data, which is the standard mode of operation for modern keyloggers. Keelog has also introduced the first PS/2 keylogger with USB data retrieve, the first Wi-Fi wireless keylogger, and the first miniature video-loggers. For more information, go to the about us page.

The KeyGrabber TimeKeeper series contains a built-in time-tracking module and battery. The keylogger will create time and date stamps in the log file, meaning you can gain information not only what keys were pressed, but also the exact time they were pressed. The TimeKeeper series is targeted especially at forensic applications, where timestamps often are a crucial part of evidence. TimeKeeper keyloggers, just like all other KeyGrabber products, offer the option of data encryption with a 128-bit key. This ensures that the data has not been tampered with and may serve as legal evidence.

A hardware keylogger is a clever concept, but it primarily provides keystroke information. It cannot provide much information about what was really happening on the target computer. Why not take key logging to the next level and log entire screenshots instead of only keystrokes? That's precisely what Keelog did with the world's first hardware video-logger: the VideoGhost.

The VideoGhost is a tiny frame grabber that silently records screenshots and stores them as JPEGs to an internal 2GB flash disk. Simply connect the video-logger to the computers DVI, VGA, or HDMI port, and it will automatically take a snapshot every few seconds. To view the recorded images, simply switch the device to flash drive mode, and it'll pop-up as a removable disk containing recorded JPEGs. Just like hardware keyloggers, the VideoGhost video-logger is a purely electronic device, meaning it requires no software or drivers, and does not interfere with the standard video transmission to the monitor or TV.
