Greenbone Review: Overview, Features, Pricing & Alternatives in 2025

Is your vulnerability management dragging you down?

If you’re here, you’re likely worried your current tools aren’t keeping up with your organization’s growing exposure to new threats.

The reality is that unpatched vulnerabilities keep exposing your network every day, leaving you anxious about unexpected breaches or failed audits.

After thoroughly evaluating Greenbone’s vulnerability management framework—especially its use of the OpenVAS scanner and daily-updated feeds—I found their platform brings real-time visibility and automation that most alternatives just can’t match.

In this review, I’ll show you how Greenbone helps you close those security gaps fast by automating continuous scanning, alerting, and compliance checks across your environment.

You’ll discover in this Greenbone review how its features, pricing, integrations, and reporting stack up against your current shortlist, and what to expect if you book a demo or try it yourself.

You’ll leave with the practical insights and features you need to make a confident, informed choice.

Let’s dive into the analysis.

Greenbone Overview

Greenbone has been committed to proactive vulnerability management since their 2008 founding in Germany. Their entire mission is built on identifying IT security weaknesses before attackers can exploit them.

They serve a wide market from SMBs to enterprise, but what really sets them apart is their dedicated focus on organizations valuing open-source transparency. This makes them a particularly strong fit for your team if you require verifiable security.

I took note of their 2023 conversion into a stock company, which signals a serious investment in future growth. Through this Greenbone review, you will see this maturity reflected.

Unlike competitors like Tenable that often lead with proprietary platforms, Greenbone’s approach feels fundamentally more transparent. Their key value is the trust built on their open-core model, offering you genuine flexibility and truly auditable security.

They work with over 50,000 installations worldwide, serving government agencies and private firms alike. You’ll notice their strong foothold in sectors that require strict on-premise data control.

From my analysis, their current strategy is delivering comprehensive security intelligence with fully verifiable results. This directly addresses the market’s growing distrust of black-box solutions and your need for genuinely auditable security tools.

Let’s dive into their feature set.

Greenbone Features

Worried about unseen vulnerabilities in your network?

Greenbone features provide a comprehensive approach to vulnerability management that helps you proactively identify and mitigate risks. Here are the five main Greenbone features that enhance your security posture.

1. Vulnerability Scanning (OpenVAS Scanner)

Are unpatched systems leaving you exposed?

Manual security checks often miss critical weaknesses, putting your entire infrastructure at risk. This can lead to costly data breaches.

The OpenVAS scanner performs deep unauthenticated and authenticated testing, covering a vast range of protocols and devices, even industrial ones. What I found particularly effective is its ability to check both IT and operational technology (OT) environments for vulnerabilities, missing patches, and misconfigurations. This core feature ensures comprehensive coverage.

This means you get a complete picture of your network’s weaknesses before attackers can exploit them.

2. Greenbone Security Feed

Struggling to keep up with new threats?

Outdated vulnerability definitions leave you blind to the latest attack vectors. You can’t protect against what you don’t know.

The Greenbone Security Feed provides daily updates with over 150,000 vulnerability tests, keeping you ahead of emerging threats. From my testing, this continuous update mechanism is absolutely critical for maintaining an accurate and up-to-date security posture. This feature ensures your scans are always relevant.

So your security team can respond quickly to new risks as they emerge, reducing your exposure window.

3. Vulnerability Management Daemon (gvmd)

Is managing scan results a chaotic mess?

Disparate scan data makes it hard to prioritize and track remediation efforts. This fragmented view hinders effective vulnerability management.

The gvmd acts as the central service, consolidating raw scan data into a full vulnerability management solution. It controls the OpenVAS Scanner and efficiently manages scan results and configurations in a robust PostgreSQL database, which I found to be very reliable. This feature also handles user and permission management seamlessly.

This means you gain a unified, organized view of all your vulnerabilities, simplifying your remediation workflow.

4. Greenbone Security Assistant (GSA)

Is your vulnerability data hard to access?

Complex command-line interfaces or clunky tools can make security management a nightmare. You need quick, clear insights.

The Greenbone Security Assistant (GSA) is an intuitive web-based interface that provides easy access to all vulnerability information. What I appreciate is how the full-featured web application streamlines interaction with the gvmd, making it user-friendly. This feature helps you control scans and access reports effortlessly.

So you can quickly analyze findings, track progress, and make informed security decisions without a steep learning curve.

5. Reporting and Alerting

Are critical vulnerabilities getting lost in the noise?

Without clear reporting and timely alerts, high-severity issues can go unnoticed. This leads to delayed responses and increased risk.

Greenbone generates detailed, customizable reports on detected vulnerabilities, including severity and remediation steps. The system also supports automatic email notifications based on specific criteria, which I found to be highly useful for immediate action. This feature helps you prioritize and target remediation efforts effectively.

This means your team receives actionable intelligence promptly, allowing for targeted and efficient mitigation of your highest risks.

You’ll appreciate how these Greenbone features work together to create a holistic vulnerability management system that offers continuous security assessments.

Greenbone Setup

Navigating the path to successful software deployment?

This Greenbone review section analyzes what it truly takes to deploy and adopt their solutions, from initial setup to ongoing success, helping you set realistic expectations for your business.

1. Setup Complexity & Timeline

Is Greenbone implementation a quick win?

Greenbone’s setup complexity varies; Community Edition (OpenVAS) is straightforward as a pre-built VM, while Enterprise Appliances are “turn-key” within minutes for virtual deployments. What I found about deployment is that integrating comprehensive vulnerability management requires careful planning, extending overall implementation.

You’ll need to account for network configuration and the specific product chosen when planning your timeline.

2. Technical Requirements & Integration

Expect specific infrastructure considerations.

Greenbone requires careful network configuration to ensure the scanner reaches all target components, whether you choose hardware, VM, or cloud-native. From my implementation analysis, integration with existing security tools might need custom development, despite Greenbone’s open standards focus.

Your IT team should assess current infrastructure and prepare for potential API-driven integrations with SIEMs or ticketing systems.

3. Training & Change Management

Don’t underestimate user adoption.

While the web interface (GSA) is central, understanding vulnerability nuances, report analysis, and prioritization requires training. From my analysis, successful adoption relies on continuous learning to maximize the value of detected vulnerabilities and drive effective remediation processes.

You’ll want to invest in internal training programs and leverage Greenbone’s documentation to ensure your team’s proficiency.
