What is WebSensing?

WebSensing is a cyber security company specializing in single-chip network security solutions leveraging System-On-Chip (SoC) and Field Programmable Gate Array (FPGA) Architectures through High-Level Synthesis (HLS). We are proudly based in New Hampshire. 

How can I get in touch with WebSensing?

Please email us at with the details of your inquiry and we will get back to you as soon as possible. 

How can WebSensing help me?

WebSensing has a variety of products which can both defend systems against cyber threats and securely streamline processes for analytics integration. For more details on our capabilities, see Technologies

Why do I need cyber security?

As an increasing number of systems are digitised, these systems become vulnerable to cyber attacks. Cyber security measures proactively protect your network and systems from such attacks.  


In the United States, network intrusion attacks—which WebSensing's products defend against—are the second most common type of cyber attack (32%) according to BakerHostetler. Similarly, Centrify identified the primary attack points for data breaches in the United States, finding that network and cloud ranked second and third behind software. 

Are there any non-cyber security benefits to WebSensing products?

Yes. While cyber security is our main value proposition, our products have additional benefits such as secure cloud analytics integration and consequential efficiencies.  

What is an FPGA?

A Field Programmable Gate Array (FPGA) is a reconfigurable electrical circuit. This allows the device to be customized to specific customer needs. While in general these devices can can be updated in the field, they can also be “locked down” protect secrets, and “wiped” to prevent tampering or reverse engineering.

What is an SoC?

A System-on-Chip device — such as the Xilinx Zynq-7000 or UltraScale MPSoC / RFSoC  — combines multiple, high-performance real-time and general-purpose processing cores with a large Field Programmable Gate Array (FPGA), bootstrap encryption hardware, high-performance memory and communication interfaces, advanced signal processing capabilities, and a broad variety of peripheral interfaces  -- all within the security perimeter afforded by a single chip. This encapsulation hides sensitive keys, busses, and algorithms mitigating reverse-engineering and making it extremely difficult to extract useful information from captured systems on tactical timescales. It also provides an unprecedented opportunity for both systems integration and hardware acceleration.

What is a High Level Synthesis?

High Level Synthesis is a design methodology that allows FPGA circuits to be implement directly from ordinary systems code — written in C, C++ or SystemC -- largely eliminating conventional circuit design in Verilog or VDL. This provides a rapid, highly integrated software/hardware design, co-simulation, and validation process; it provides a new level of flexibility in integrated systems combined with advanced, system- and algorithmic-level optimization benefits.

What is SNMP?

The Simple Network Management Protocol (SNMP) is an internet standard for managing and monitoring network appliances --- such as routers, switches, servers, printers, etc.

What is a hardware turnstile?

A hardware turnstile is a mechanism built into our Gateway product that allows a receiver to indicate to the sender that it has received all of its data — without direct reverse communication. This allows large files and databases to be replicated at remote sites through a diode, thereby protecting the sender.

What is a network backchannel?

A backchannel is a completely separate connection allowing management of a network appliance that does not use its standard communication interfaces. The use of a backchannel allows a network appliance to be monitored and updated from an alternative, isolated network making the appliance less vulnerable to network attacks.

What is a VIN?

A virtual isolated network (VIN) is a hardware solution to replace physical airgaps. As an alternative to increasingly impractical and expensive airgaps, Web Sensing has developed the VIN – an electronic airgap realized through FPGA technology. The VIN is designed for organizations that want a middle ground between an air-gapped network and one that is connected to the Internet such as a virtual private network (VPN), which lacks the protections of a VIN. 

What is a diode?

A Diode is a network device that permits network traffic to flow in only one direction across it. Any device connected to a Diode will be able to either send network traffic or receive it, but not both.


A Diode allows businesses to connect sensitive corporate assets to the Cloud for analysis, without permitting any traffic -- or embedded attacks -- to reach back to the asset from the Internet.

What is a kernel integrity monitor?

The Web Sensing Linux Kernel Integrity Monitor (LKIM) is a device that is hidden within a computer and monitors the Linux Operating System and its associated Device Drivers for Kernel-Level Zero-day Attacks. A Zero-day Attack is an advanced cyber-attack that has not been seen previously by network defenders and consequently cannot be detected by anti-virus software.
