Businesses are always looking for ways to improve their security posture and protect their systems from unauthorized access or exploitation. One way to do this is by conducting vulnerability scans and penetration tests. There is a lot of confusion between vulnerability scans and penetration testing. Many individuals are unaware of the distinction or mistake them for the same thing. While both of these activities have similar goals, they are actually quite different.

In this blog article, we’ll go through vulnerability assessment vs penetration testing in-depth, so that you can make an educated decision about which one is ideal for your company.

What Are Vulnerability Scans?

A vulnerability check is a computer program that determines whether a system has any security flaws and is performed by the organization or an external team.

Vulnerability scans use a variety of methods to identify vulnerabilities, such as network mapping, banner grabbing, and port scanning. After the scan is finished, a report is generated that summarizes all of the discovered flaws and associated threats.

What Are Penetration Tests?

Penetration tests or pen tests are simulations of real-world attacks that are used to assess a system’s security. Penetration testing, unlike vulnerability scanning, is not automated. They are carried out by ethical hackers (also known as white hat hackers) who attempt to exploit vulnerabilities in order to gain access to the system.

Penetration tests can be conducted externally or internally, depending on the scope of the test. External tests are typically more comprehensive, as they simulate real-world attacks that would come from outside the organization. Internal tests are usually narrower in scope and only focus on testing internal systems and networks.

How Are Vulnerability Scans And Penetration Tests Different?

Now that we’ve explained what vulnerability scans and penetration tests are, let’s take a look at how they differ from each other:

  • Vulnerability scans are automated while penetration tests are not.
  • Vulnerability scans identify potential vulnerabilities while penetration tests attempt to exploit them.
  • Internal or external vulnerability scans are available, while penetration tests are often done remotely.
  • Vulnerability scans use a variety of methods to identify vulnerabilities while penetration tests only use one: exploitation.
  • A scan of your website’s security exposes any potential vulnerabilities and their associated risks. Penetration tests do not always generate a report, but if they do, they will only list the exploited vulnerabilities.

Tools for Vulnerability Scans and Penetration Tests

There are a number of different tools for performing automated vulnerability scanning and penetration testing. Here are the ones you can opt for:

  • Astra’s Pentest Suite
  • Nessus
  • Qualys Guard
  • IBM AppScan
  • HP WebInspect
  • McAfee Foundstone Ultimate Hacking
  • Core IMPACT Pro
  • Metasploit Framework

Each of these tools has its own unique features, so be sure to do your research before selecting one. When purchasing a tool, you’ll have to consider your budget as some of them may be quite costly.

Use a Vulnerability Scan or a Penetration Test- Factors In Deciding?

So, what method is the better alternative for your business? The decision is based on your objectives and goals. If you’re looking for a quick and easy way to identify potential security weaknesses in your system, then a vulnerability scan is the way to go. However, if you’re looking for a more comprehensive assessment of your system’s security, then a penetration test is the better option.

When deciding whether to conduct a vulnerability scan or penetration test, there are a few factors you’ll need to consider:

  • What are your goals and objectives?
  • Do you want a quick overview of potential security weaknesses?
  • Or do you want a more comprehensive assessment of your system’s security?
  • What is your budget?
  • And finally, what tool will you use?

Once you’ve completed these questions, you’ll have a better sense of which sort of test is appropriate for your company.

Vulnerability scans are best suited for businesses that want a quick overview of potential security weaknesses. Penetration tests are best suited for businesses that want a more comprehensive assessment of their system’s security. Finally, you should pick a tool based on your budget and objectives.
