Monitor and Protect Your Entire Attack Surface With Continuous Vulnerability Assessment
Vulnerability assessment gives you comprehensive insight into the cyber exposure of all your assets, including vulnerabilities, misconfigurations and other security health indicators. With Nessus, you can be confident that your vulnerabilities and misconfigurations are remediated as you expect them to be. You can also automatically send related information directly to your Security Information and Event Management (SIEM) system to help you make more informed decisions about how to respond to weaknesses discovered within your network.
Gartner's Market Guide for Vulnerability Assessment
Need help evaluating a vulnerability assessment vendor so you can improve your overall security program?
Gartner’s Market Guide for Vulnerability Assessment is a great place to start. In this guide, you’ll learn about common use cases and challenges for vulnerability assessment solutions, recommendations for requirements, tips on choosing a vendor, and how to map vendor capabilities to address the challenges your enterprise security team faces.
Quantifying the Attacker’s First-Mover Advantage
Who has the first-mover advantage — cyber criminals or security teams? What’s the time difference between the moment an exploit is publicly available and the first time your security team assesses your system? Do you know why this matters to your organization?
In this report, Tenable Research shares what it discovered after analyzing about 200,000 vulnerability assessment scans over more than three months. The team took a close look at the 50 most prevalent critical and high-severity vulnerabilities discovered. From the review, researchers determined the median delta between “time to exploit availability” and when the threat is actually assessed.
From continuous vulnerability assessment to ways you can proactively address risks, the report also provides insight into what you can do to thwart attackers’ first-move advantages so you can close the gap for your organization.
Here are a couple other key points:
- On average, attackers have more than a seven-day advantage over your security team
- For about 34% of the vulnerabilities studied, an exploit was available the same day as the vulnerability disclosure
The Economics of Vulnerabilities
and Exploit Supply Chains
It Can Be a Lucrative Market for Attackers
Taking advantage of vulnerabilities and successfully turning them into exploits can be a lucrative business for attackers. Different types of exploits earn them varying pay-offs. In some cases, a single successful exploit can net millions.
In cybercrime money-laundering alone, the totals can easily hit $200 billion, which significantly overshadows the worldwide cybersecurity spend – how you’re protecting your organization – at $136 billion.
The exploit supply chain is sophisticated and challenging to detect, and so are related market segments. Exploit white and black markets intersect for both criminal buyers and legitimate ones, where the gray market is primarily driven by covert nation-state actors targeting data for intelligence.
Attackers appear to have more resources to target your network than you do to protect it, and when your security team is constantly playing catch-up, it’s challenging to close the gap between your risks and their bad intentions.
If you’re a CISO, security practitioner, or security manager, you’ll want to get this report now to take a closer look at the market dynamics that fuel the vulnerability and exploit supply chain, and learn more about what you can do to keep your network safe.
How Mature Are Your Cyber Defender Strategies?
Understanding What Your Vulnerability Assessment Strategies Reveal
When it comes to vulnerability assessment, Tenable Research discovered four distinct assessment types. From the most mature style to the least, they are Diligent, Investigative, Surveying and Minimalist. Here’s an overview of each:
This is the highest level of vulnerability assessment maturity. Only about 5% of all organizations are Diligent. Transportation, hospitality, electronics, banking and telecommunication industries make up the majority.
This is a medium-to-high level of maturity. Most enterprises, about 43%, are Investigative. Entertainment, utilities, education and healthcare comprise most of the Investigative style category.
This is a low-to-medium level of maturity, representing about 19% of organizations. Overall, the utilities industry has the largest representation of Surveying styles.
This is the lowest maturity level and represents about 33 percent of enterprises, with a fairly even representation of industries across the style profile.
You can get insight into your own vulnerability assessment style by evaluating five related Key Performance Indicators (KPIs): scan frequency, scan intensity, authentication coverage, asset coverage and vulnerability coverage.
In this report, you can also get more information about characteristics related to each vulnerability assessment style, ways to understand how your style compares to peers within your industry, and recommendations to enhance the maturity of your vulnerability assessment style.

How do I generate a report from already scanned systems?
I performed a vulnerability assessment on 100 of our systems last week in one scan. Now I want to get a report of 3/4 IP address from 100 systems. How do I do this?See the Answer
How does Nessus handle backported patches?
Nessus relies on backport.inc to prevent false positives. backport.inc contains mappings of known service banners to service banners that have arbitrarily high version numbers.See More of This Answer
How are PCI quarterly external and internal PCI network scans different?
While the PCI quarterly external policy is valid for official attestation, both policies can be used any time for scanning.See More of This Answer

Vulnerability Assessment Solutions
Continuous vulnerability assessment is an important component of your overall vulnerability management program. Vulnerability assessment gives you insight into where you have cyber exposure within your attack surface, the volume and types of vulnerabilities that may be exploited, and the potential risk these vulnerabilities could pose to your organization. Vulnerability assessment helps you uncover these risks for prioritization.
Today, your modern attack surface consists of a variety of assets, including traditional IT, transitory, mobile, dynamic and operational technology. Without complete visibility into your attack surface, assessing vulnerabilities and misconfigurations across all of these devices is challenging; however, a single vulnerability assessment platform like Nessus can give you a unified view of all of your exposures and vulnerabilities.
Here’s a closer look at the benefits of vulnerability assessment and why it’s an important process for your organization to adopt as part of your comprehensive cybersecurity program.
Vulnerability Assessment Benefits
Cyber Exposure Awareness
Vulnerability assessment can help your team identify vulnerabilities, misconfigurations and other weaknesses across your entire attack surface.
Configurations and Audit Patching
Vulnerability assessment helps ensure you can remediate vulnerabilities and misconfigurations as outlined by your organizational goals.
Incident Management Information
With vulnerability assessment, you can automatically send vulnerability and misconfiguration information to your SIEM to enrich event data, help prioritize events for investigation and inform team responses.
Vulnerability assessment gives you insight into your current cybersecurity processes so you can evaluate how effective they are and what you can do to improve your overall program.
