Vulnerability Management: The Complete Guide
Vulnerability management is an ongoing process to identify and remediate cyber risks, vulnerabilities and misconfigurations across your entire attack surface, both on-prem and in the cloud.
It includes proactive asset discovery, continuous monitoring, mitigation, remediation and defense controls. If you’re a cybersecurity executive who needs a refresher, an emerging vulnerability management practitioner or are considering purchasing a vulnerability management platform to decrease your exposure, this page is your go-to hub for vulnerability management knowledge.

Elevate your vulnerability remediation maturity: A four-phase path to success
Cyber threats are on the rise. As organizations expand their digital attack surfaces, it increases their risk. However, expanding attack surfaces put security teams in a constant loop of finding and fixing vulnerabilities often without context about which exposures actually put the organization at risk. Without a risk-based approach to vulnerability management, it's nearly impossible to get a strategic view of effective vulnerability remediation. On top of that, many organizations still use slow, manual processes and disparate technologies that make it increasingly difficult to see all vulnerabilities across every asset.
This white paper explores a four-step approach to increase vulnerability remediation maturity. Through each phase, you can learn more about industry recognized best practices to dig out of the mountain of vulnerabilities created by traditional vulnerability management practices.

How to implement risk-based vulnerability management
As your attack surface evolves and attack vectors increase, it can be difficult for your security teams to stay ahead of vulnerabilities. That's even further complicated if your organization has assets in the cloud and your team still uses vulnerability management practices designed for on-prem devices.
This ebook outlines how to implement a vulnerability management program by shifting to a risk-based strategy. A risk-based vulnerability management approach helps you more effectively protect your complex attack surface. By using AI and machine-learning-generated models, your teams can get valuable prioritization insight into vulnerabilities that pose an actual threat to your organization and know how and when to remediate them.

- How to implement a risk-based vulnerability management program
- How machine learning can help your teams reduce risk with less effort
- Five steps of the risk-based vulnerability management lifecycle
Overcoming challenges created by disparate vulnerability management tools
Ditch your fragmented toolset for more effective risk assessments and management.
For far too long, security teams have struggled to build a comprehensive vulnerability management program by piecing together disparate tools to handle network vulnerabilities, cloud security issues and web application security. The result is often massive amounts of siloed data that make it nearly impossible to get a complete picture of what’s happening across your expanding attack surface. With traditional vulnerability management solutions, there’s rarely valuable insight into which vulnerabilities pose greatest risk to your organization or recommendations on best practices to remediate them.
The good news is there is a better way to manage and protect your attack surface and you don’t need multiple tools to do it.
Read this white paper to learn more about:
- Why fragmented tools cause you to miss vulnerabilities and the operational impact
- How emerging security threats target multiple environments at the same time
- How a unified vulnerability management program can help you more effectively assess and defend your entire attack surface
The state of vulnerability management
Tenable and HCL Software commissioned a study of more than 400 cybersecurity and IT professionals to get insight into the current state of vulnerability practices. The survey focused on vulnerability identification, prioritization and remediation, with emphasis on current priorities and challenges.
The report found that since both IT and security teams contribute to vulnerability management, the lines can blur between who is responsible for what. This blurred area is one of many security weaknesses bad actors are hoping to take advantage of. They're constantly trying new and more sophisticated tactics, making it increasingly hard for IT and security teams to expose and close critical weaknesses across their vast attack surfaces.

- Key vulnerability management trends
- Respondent thoughts about finding, prioritizing and remediating vulnerabilities
- The relationship between IT and cybersecurity for vulnerability management

Vulnerability management is a way to reduce risk for your organization, no matter how large or small it may be. However, creating a mature vulnerability management program is not a simple task. It requires goal setting, metrics, continuous discovery, monitoring and buy-in from stakeholders across your organization. Not sure where to start? You can make your vulnerability management process stronger with these five best practices:
-
Discover
Identify and map every asset across all of your computing environments. Continuous discovery and complete visibility into your environment can be challenging without the right vulnerability management tools, but it is vital for discovering and preventing blind spots in your attack surface.
-
Assess
Evaluate the exposure of all of your assets, including vulnerabilities, misconfigurations and other security health indicators. Comprehensive vulnerability and misconfiguration assessment is more than running a scan. It’s also using a range of data collection technologies like you’ll find in Tenable Vulnerability Management to identify diverse security issues for your organization.
-
Prioritize
Understand cyber risk in context of your security and business goals to prioritize remediation based on asset criticality, threat context and vulnerability severity.
-
Mitigate
Leverage AI and machine learning to spot hidden data patterns that correlate with future threat activity. This will give you insight into vulnerabilities that may have the highest likelihood of near-term exploitation. From there, prioritize which exposures to mitigate first and then apply the appropriate remediation process.
-
Measure
Measure and benchmark your cyber risk to make better-informed business and technology decisions. Report customization in Tenable Vulnerability Management will provide you with easy-to-understand data about the effectiveness of your vulnerability management program and external benchmarking metrics to help you compare your program performance against similar businesses in your industry.
Vulnerability management and protecting your enterprise from cyber threats
For many years, security teams have focused their vulnerability management practices only on their department or team goals. While that traditionally had a degree of success, enterprise vulnerability management programs that align security goals with business goals tend to be stronger.
By aligning your vulnerability management program to your business goals, you can more easily create and analyze success metrics that enable you to communicate your program success to key stakeholders — like C-Suite executives and board members — in ways they understand. This can help you build a stronger cybersecurity program and get the support of upper-level management so you can access resources to keep your program flexible, scalable and successful. Here are five best practices for enterprise vulnerability management:
-
Establish goals
Identify specific components that are measurable and meaningful and then begin attack surface hardening, asset inventory and patch auditing.
-
Ensure data accuracy
Don't limit the view of your total state of vulnerability. Ensure you're accessing accurate data that’s actionable and timely.
-
Account for gaps
To maintain reliable processes and build trust, quickly identify sources where you have patching issues and track them as exceptions.
-
Deal with interdependencies and conflicts
Understand how processes affect individuals and teams within your organization to create a successful vulnerability management program.
-
Know what to measure
Instead of trends, focus measurement on exceptions to discover weaknesses.
Eliminate blind spots. Boost productivity. Prioritize vulnerabilities.
