ABOUT THE VENDOR

Greenbone & OpenVAS

Greenbone’s origin

Greenbone is a German cyber security vendor that provides commercial vulnerability management products and maintains the open‑source Greenbone Community Edition, widely known as OpenVAS. OpenVAS serves as the core technology behind the company’s commercial offerings. Greenbone’s portfolio includes hardware appliances, software appliances, and cloud‑based solutions. Historically, the company has concentrated on serving government organizations in Germany, largely through hardware‑based deployments.

Nessus & OpenVAS

In 2005 and the years that followed, the Tenable Nessus scanner became a closed-source commercial product, forking into several different projects, including the open-source project OpenVAS (since maintained by Greenbone).

OpenVAS powers today’s vulnerability management products

OpenVAS has proven to be a powerful and reliable technology, becoming the de facto standard for system and network scanning. Over the years, it has formed the foundation for many vulnerability management platforms and products - including Holm Security’s System & Network Security offering.

COMPARISON

The modern approach to vulnerability & exposure management

Although Greenbone and Holm Security share the same OpenVAS technology foundation, the two platforms differ significantly in scope and capabilities. Greenbone remains a traditional vulnerability management solution focused on conventional attack vectors. Holm Security, on the other hand, takes a more modern approach - covering a wider range of attack vectors and adding advanced capabilities across ASM and EASM, areas that today are central to exposure management.

The platform also brings together capabilities such as ASM, EASM, and ASV scanning to give organizations comprehensive visibility across their entire attack surface. 

In other words, Greenbone provides traditional vulnerability management, while Holm Security offers what is now widely referred to as exposure management - delivering broader coverage and a more modern approach to reducing risk.
