Best Azure Penetration Testing Tools

Microsoft Azure is a virtual server service that also provides services, such as databases. While Azure maintains the services that it supplies, account security and the integrity of the software that you install are your responsibility.

There are a number of tools that you can use to perform automated sweeps of your Azure resources and others that you can use to support your own penetration testing exercises.

Here is our list of the nine best Azure penetration testing tools:

  1. Intruder EDITOR’S CHOICE A cloud-based vulnerability scanner that can be launched on demand or on a schedule. Enjoy unlimited on-demand scanning for continuous security monitoring of on-premises systems and cloud services, including Azure accounts. Get a 14-day free trial.
  2. Invicti A package of testing systems that can be used for automated procedures during penetration testing, as a vulnerability manager, or as a continuous testing tool in a CI/CD pipeline. This system is available as a SaaS package or as software for installation on Windows.
  3. Acunetix This vulnerability scanner for Web applications and networks can be used as a penetration testing tool and it is able to scan a range of systems, including Azure. Available as a SaaS platform or for installation on Windows, macOS, and Linux.
  4. Azucar A free PowerShell utility that runs on Windows but probes the statuses of Azure services, particularly Azure AD and databases.
  5. BloodHound Offered in free and paid versions, this tool focuses on attack strategies that can hit Active Directory implementations, including Azure AD. It runs on Windows, macOS, and Linux.
  6. PowerZure This free PowerShell utility is built to assess the security of Azure services with permission. It runs within your Azure account.

You can read more about each of these tools in the following sections.

Penetration testing is a manual process. Automated security tools are called vulnerability managers. There are some tools that fall between these two categories. These are able to perform repetitive tasks, such as brute force password guessing but they don’t sequence through a full series of vulnerability checks. Some packages can be set to operate as vulnerability managers or as penetration testing tools.

Azure penetration testing ground rules

Microsoft expects customers of Azure to test the system for security weaknesses and even invites account holders to report discovered weaknesses that require system fixes to resolve.

There are just a few rules that you need to stick to when performing penetration testing on Azure. If you break these rules, you could get your Azure account shut down or even get sued.

The rules you need to follow are:

  • Don’t try to break into the accounts of other Azure customers – stick to your own account.
  • Don’t try to capture or alter the data of other Azure customers.
  • Don’t attempt phishing, doxing, or social engineering on Azure technicians.
  • Don’t perform a DDoS attack.
  • Don’t use automated testing utilities that generate a high volume of traffic in a short space of time.
  • Don’t break the Microsoft Online Subscription Agreement.

For more information, see the Azure guidance on penetration testing.

The rules that Microsoft imposes on testing for Azure accounts might tie the hands of many white hat hackers, who are willing to try any of the techniques used by hackers in order to test the security of a system.

It could be said that you won’t get a full assessment of your Azure account’s resilience to hacker attack if your penetration testing tool is tied by the rules laid down for the use of an Azure account.

Some independent penetration testing services might prefer to break the rules. You might think that contracting a consultancy to break into your Azure account gets around the restrictions imposed by Microsoft. However, they don’t because the service argues that you should specify the parameters of an investigation when you agree to a contract with the penetration testing service so that banned activities are prevented.

Best Azure Penetration Testing Tools

Although penetration testing is a specialized niche in IT security management, there is a surprisingly wide definition of what constitutes a penetration testing tool. Many commonly-used network management utilities that are built into the operating system can be used for system research. Ping, for example, is often used to probe networks both by network administrators and by hackers.

This means that this guide will present a range of tools that include system probes and attack utilities.

Our methodology for selecting Azure penetration testing tools:  

We reviewed the market for Azure penetration testing packages and analyzed tools based on the following criteria:

  • A probe or a hacking utility that can examine an Azure resource from an external location.
  • A degree of automation
  • A tool that can speed up checks for the OWASP Top 10
  • Systems that can run on Linux or Windows
  • Cloud-based options
  • A free tool or a free trial period to assess the tool without paying
  • Value for money from a useful utility or a free tool that is worth getting to know

As penetration testing models the behavior of hackers, tools for the job don’t need you to log into the system first. This also means that these penetration testing systems are versatile and not limited to probing one specific system. They can usually test on-site systems and a range of cloud platforms, such as Azure and AWS.

This list includes both free and paid tools. You should expect to get a better interface and more capabilities from the paid tools than from the free systems. However, you can put together your own penetration toolset by selecting a number of these recommended utilities.
