If there’s anything we learned from years of working in infosec is this: don’t make assumptions without knowing the context and make decisions based on reliable data.

With that in mind, we’ve put together this extensive list of penetration testing statistics and relevant data that shed light on many aspects of the industry.

Why are we doing this? Because it helps infosec specialists like you to get the information they need to maintain a high-level perspective while also supporting initiatives such as:

  • asking your manager for budgets

  • advocating for new team members to fill in specific gaps

  • highlighting the real business impact of people, processes, projects, and technology.

Dig into these detailed (and often surprising) pentesting statistics to find out what’s going on in the industry and how it impacts your day-to-day activities. 

Vulnerability and pentesting data

The ever-expanding threat landscape continues to impact companies globally and affect their critical infrastructure. 

That’s why it helps to take a closer look at these vulnerabilities statistics and trace their impact:

  • 363 high-risk vulnerabilities with CVSSv3 10.00 and RCE access were found last year (CVE Details)

  • According to the same database, in 2021, 1165 vulnerabilities with CVSSv3 scores of 9.0 - 10.0 emerged in the tech ecosystem

  • Almost 21,000 vulnerabilities were published in 2021, 4061 of which were flagged with high-risk CVSSv2 scores (from 7.0 to 10.0) (National Vulnerability Database)

  • The State of pentesting 2021 report from Cobalt highlights the 5 most common vulnerability categories the pentesting community discovered: Server Security Misconfigurations (28.1%), Cross-Site Scripting (15.5%), Broken Access Control (14.7%), Sensitive Data Exposure(8.4%), Authentication and Sessions (8%)

  • At least 66 zero-day vulnerabilities appeared in 2021. The fast proliferation of hacking tools on a global scale is a contributing factor to this growth rate. (MIT Technology)

A report says there were 20,174 security vulnerabilities (CVEs) published in 2021, compared to 17,049 in 2020. The 3 most common ones were: XSS, memory corruption, and SQL. (Stack Watch 2021 Vulnerability Report)

  • Fixing a critical vulnerability took companies 193.1 days on average in 2021(AppSec Stats Flash - Year in Review). The 3 top industries with the longest time to fix them were: education (523.5 days throughout the year), arts and entertainment (493.8 days), plus retail trade (497.7 days).   

  • Statista says that over 1 million companies worldwide use the Microsoft Office 365 suite. So it’s no surprise it remains an attractive attack vector.

  • The top 3 most notable critical Microsoft vulnerabilities, which CISA added to their list of most exploited vulnerabilities in 2021, are ProxyLogon (CVE-2021-26855 and CVE-2021-27065), ProxyOracle (CVE-2021-31196 and CVE-2021-31195), and ProxyShell (CVE-2021-34473, CVE-2021-34523, and CVE-2021-31207) (HelpnetSecurity). 

  • More data from the AppSec Stats Flash report indicates that remediation rates for critical vulnerabilities saw a decline from 54% in 2020 to 47% in 2021.

The deeper we go into vulnerability data, the more visible the importance of vulnerability scanning and prioritization for companies becomes.

Vulnerability assessment statistics

Vulnerability assessment (VA) is an essential process for businesses that want to identify and understand high-risk vulnerabilities in their attack surface before attackers have a chance to exploit them.   

Check these stats to see how other organizations fare and what goals cybersecurity peers have in this area: 

  • Over the next 5 years, the VA market will grow at a 10% CAGR (Compound Annual Growth Rate) (Mordor Intelligence Report)

  • One in five organizations do not test their software for security vulnerabilities (Ponemon Report: Application Security in the DevOps Environment)

  • 70% of organizations have a vulnerability assessment tool - deployed internally or provided as a third-party service (2022 Vulnerability Assessment Analytical Note)

  • 70% of respondents acquired a vulnerability assessment tool for proactive security measures (2022 Vulnerability Assessment Analytical Note)

  • 52% of them want to change to a new assessment solution to reduce false-positive alerts (2022 Vulnerability Assessment Analytical Note)

  • It’s important to find a vendor that can align with your organization’s computing architecture. (2021 Gartner Market Guide for Vulnerability Assessment)

  • Gartner’s report also found most users still focus on traditional VA solutions (e.g. Tenable, Qualys)

It’s worth mentioning that VA vendors have evolved from scanning to providing support throughout the Vulnerability Management (VM) process. They also offer tighter integration with other tools to suggest inefficiencies across the VM process.

Vulnerability management figures

The staggering number of vulnerabilities highlights the need for an effective vulnerability management program. But do organizations really prioritize vulnerability management practices? 

Let’s see some vulnerability management data to see what happens when theory meets practice.

  • The National Institute of Standards and Technology (NIST) recommends vulnerability scans to run at least monthly and even more frequently for organizations that collect and/or process personal or sensitive data.

  • 31% of IT pros do their own vulnerability scanning, while another 33% say they don’t do any regular vulnerability scanning. (RapidFireTools Survey)

  • 59% of organizations do not plan on prioritizing vulnerability management in 2022 (2022 Endpoint Management and Security Trends Report)

  • Only 4 out of 10 organizations prioritize endpoint vulnerability management in 2022 (2022 Endpoint Management and Security Trends Report)

  • Information security is the most common group within organizations responsible for overall vulnerability management (74%). It focuses on remediation activities such as patching (67%) and configuration management (69%) (SANS Vulnerability Management Survey 2020)

  • The same SANS survey shows that 18% of respondents automatically scan for vulnerabilities or misconfigurations in their cloud PaaS environments. 22% of them do so in cloud SaaS environments.

  • The market will grow from USD 6.7 billion in 2020 to USD 15.86 billion by 2030, at a CAGR of 9% during the forecast period 2021-2030. (PRNewsWire.com)

The New Vulnerability Management Guidance Framework from Gartner indicates some important areas of focus when evaluating this process:

  • Vulnerability management guides other critical areas that need security improvements in organizations. 

  • Identifying critical vulnerabilities is one of the main objectives of the VM process.

  • Successful VM programs support advanced prioritization techniques and automated workflow tools. Why? To streamline the handover to the team responsible for vulnerability remediation.


5 stages of the vulnerability management  lifecycle

Vulnerability prioritization – key data

An essential aspect of the vulnerability management program is vulnerability prioritization. 

With so many high-risk vulnerabilities – and based on their CVSS score – this phase is vital to close potential security holes and reduce adversaries’ window of opportunity. 

So let’s take a closer look at some important data infosec leaders should focus on when prioritizing:

Members of our community shared their perspectives and experience on the topic in the comments of this survey on LinkedIn.

  • Only 33% of organizations prioritize implementing Zero Trust and multifactor authentication (MFA) (2022 Endpoint Management and Security Trends Report)

  • 34% of businesses don’t prioritize risks for their IT teams. (TAC Security Survey)

  • 88% of businesses review security risks on their own, rather than using a vulnerability management solution. (TAC Security Survey)

These stats show that prioritization is still lacking standardization as part of vulnerability management. Since it’s a nuanced process with complex implications, companies still have a long way to go to significantly reduce their exposure caused by high-risk vulnerabilities. 

The 2021 Gartner Market Guide for Vulnerability Assessment emphasizes the following:

  • Prioritization does decrease the number of vulnerabilities that need remediation right now. For bigger companies, this goal is strengthened by orchestration. 

  • Prioritization by a Vulnerability Assessment vendor is a good starting point for small and mid-size clients.

  • Prioritization is of prime importance for effective risk reduction.
