Features Of Good Cloud Penetration Testing Tools

1. Zero False Positives

The company that provides cloud pentesting should provide a zero false positive assurance for vulnerability detection. This should be done with the help of expert pentesters who can double-check the results of an automated vulnerability scan to ensure that every vulnerability found is legitimate.

2. CI/CD Integrations

Ensure that the cloud penetration testing tools you have narrowed down can be integrated into your organization’s CI/CD pipeline. Such integration allows your organization to shift from a DevOps model to a DevSecOps model, thus giving more priority to security. 

It should offer integrations with applications like Slack, Jira, GitHub, and GitLab to name a few important project-building applications that can use pentesting tool integration into the development phase.

3. Comprehensive Vulnerability Scanner

A vulnerability scanner with the capacity to detect business logic errors and conduct scan-behinds logins is comprehensive and standard for a good cloud penetration testing tool. 

Such vulnerability scanners should be capable of detecting all known vulnerabilities based on intel, CVEs, and vulnerabilities mentioned in other standards like OWASP, NIST, and SANs. 

4. Compliance-Specific Scans

The cloud penetration testing tool should also provide compliance-specific scans so that the cloud platform and the organizations that store their confidential data on it can stay compliant with various industry-specific regulatory standards for data protection. 

Compliance-specific scans help find areas of non-compliance if any for standards like GDPR, SOC2, ISO 27001, HIPAA, and PCI-DSS. These flaws should be listed in a special compliance report which is helpful for quick remediation thus helping avoid penalties. 

5. Detailed Reports

The hallmark of good cloud penetration testing tools lies in the detail-oriented report generated once the penetration test is complete. The report should explain in detail the scope of testing, the assets scanned, the vulnerabilities found and exploited as well as the methods used to carry out the attacks. 

Once these factors are mentioned and the vulnerabilities are listed based on their severity of risk or CVSS score, exhaustive remediation measures must be mentioned so that the organizations can take quick actions for remediation based on that. 

6. Pentest Certificate

The pentesting company should provide a penetration testing certificate upon the completion of a penetration test and the successful remediation of the flaws found. This can be double-checked by conducting a re-scan. 

The provision of a publicly verifiable pentest certificate can be an extremely useful commodity for the customers since it can increase their reliability and trustworthiness. This can boost sales and act as a hook for potential cloud customers as well.

7. Customer Support

A good penetration testing company provides 24*7 customer service through calls, and emails to clear any queries that could arise during the penetration testing process. Customer support should be done by knowledgeable experts to ensure a seamless query clearance.

Benefits of Cloud Penetration Testing

Cloud penetration testing is not only beneficial to cloud service providers, but also to the organizations that store their sensitive data and applications in the cloud. Cloud penetration testing helps maintain the shared responsibility model placed by most cloud providers between themselves and the customers through:

1. Find Vulnerabilities

Identification of any vulnerabilities by carrying out cloud penetration tests ensure their quick fixing. The comprehensive scanners can pick up even the most minute vulnerabilities. This is crucial as it helps in the immediate remediation before the vulnerability is exploited by hackers. 

2. Enhance Security

Another benefit of cloud penetration testing is that it helps with the constant updating of security measures. Not only this, it helps make the existing security measures better if any security gaps are found in them.

3. Increased Reliability

Carrying out periodic cloud pentests can help increase the reliability and trustworthiness attributed to the cloud providers. This can bring in more clients owing to the security-conscious nature of the cloud provider while keeping the existing client happy with the level of protection available for the data stored by them. 

4. Maintain Compliance

Carrying out cloud pentests not only helps find vulnerabilities but also areas of non-compliance with various regulatory standards. Thus these areas that are identified can be remedied to meet the compliance requirements and avoid fines for non-compliance.

Factors In Choosing A Good Cloud Test Tool?

1. Experience

Consider the years of experience of the penetration testing companies you have shortlisted for your needs. This can help you understand the reliability and reputation of the companies and the penetration testing tools you’re considering employing. 

2. Features Offered

Consider the features of the penetration testing tools before purchasing them as this is largely based on the needs of your company. It is important because every penetration testing tool will have varied specifications and so they need to be compared to choose the best among the options. 

3. Requirements

What are the requirements your company needs to fulfill from conducting this cloud penetration test? From compliances to just periodic penetration tests, ensure that you and the pentesting company you choose are clearly aware of your needs as this can change and affect the scope of testing and expense as well. 

4. Compliance

The company should compliance specific scans for varied compliance standards like SOC2, PCI-DSS, HIPAA, GDPR, ISO 27001, and others for your to choose from based on your compliance requirements. 

5. Pricing

Get penetration testing price quotes from various companies and compare them based on the features and the packages offered. This can help you stay well within the budget set by your company and yet get the most out of your cloud penetration test. 

6. Scalability

Ensure that the cloud penetration testing tools short-listed by you have the resources and capacity to be scaled up or down if required based on your company’s growing needs, size, and employee strength. 

What Is The Shared Responsibility Model?

The shared responsibility model is a cloud security model where both the cloud provider and customer are tasked equally with the upholding and maintenance of the cloud security in which their data and applications are stored. 

With this model, if any security breach or hack occurs it becomes easy to identify who is liable for the damages as such a breach can only occur due to neglect in security testing from either party. 

This is available for Azure and AWS where the cloud providers take care of the holistic security of the cloud while their customers are charged with maintaining the security within it. 

The type of shared responsibility model applicable changes based on the type of cloud service model opted for. Generally, the customer’s share of the responsibility increases from SaaS to PaaS and IaaS. 


Cloud computing is taking over the business by storm due to its ease of use and storage. It, therefore, becomes the responsibility of the growing number of users and providers to ensure that their customers’ data is always safe as even the cloud is prone to get hacked.  

This article has mentioned the top 5 cloud penetration testing tools, their features, pros, and cons in detail for you to peruse through. Along with this, the features of a good cloud security company and the various associated factors that are involved in making the right choice have also been mentioned. 

So make your choice wisely today and use tools like Astra Pentest and more to keep your cloud safe and sound!


1. What are the top three cloud platforms?

The top 3 well-known and used cloud platforms are AWS by Amazon, Azure by Microsoft, and GCP by Google. 

2. Top 3 cloud penetration testing methodologies?

The top 3 cloud penetration testing methodologies are: 
1. Black box: In this pentesting methodology the pentester is not aware of any target details and has to start to exploit from scratch. True hacker-style testing.
2. White box: In this type of pentesting the testing is aware of all the relevant information pertaining to the exploitation. Also known as clear-box testing.
3. Gray Box: In this type of testing details regarding the system are divulged partially.

3. What is AWS penetration testing?

This refers to the exploiting of the AWS platform service used by you to find any vulnerabilities within its security. AWS penetration testing is subject to the policies put forth by AWS.
