Vulnerability assessment is a process that identifies and evaluates network vulnerabilities by constantly scanning and monitoring your organization's entire attack surface for risks. It is the first step in defending your network against vulnerabilities that may threaten your organization.

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.

For decades, organizations looking to build the most comprehensive defenses to protect their attack surfaces have built a tech stack of disparate solutions. Every time an environment changes, security teams have generally bolted on new assessment tools to get visibility into that new environment. Unfortunately, these disparate solutions often silo data making it nearly impossible to see the big picture of your attack surface. This creates blind spots that leave doors open for attackers.

Single-purpose tools are no longer effective solutions for modern vulnerability assessments. They're burying your security teams in incomplete data that makes it challenging to understand where you have actual risk, how you should prioritize remediation, and what to do to maintain a risk-based vulnerability management program.

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.

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.

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.

The Tenable Community is a great place to ask questions and share tips, including vulnerability assessment-related tools and best practices.

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.

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.

Penetration testing is a key component of your vulnerability assessment program, enabling you to delve into your attack surface to find weaknesses and fix them before attackers harm your organization.

Conducting a vulnerability assessment has never been easier thanks to Nessus. Nessus vulnerability assessment gives you full visibility into your network so you can find vulnerabilities and make a plan to fix them. You can complete a Nessus vulnerability assessment with a few simple steps.
