5 Top Cloud Vulnerability Scanners for AWS, Google Cloud, and Azure

34% of all cloud-related data breaches can be attributed to the hijacking of privileged accounts. More than 90% of the users utilize only 5% of the access granted to them. Can you spot a pattern there? 

There is simply too much access, and too little time to review all the security controls manually. A good cloud vulnerability scanner can make a significant difference there, and we will help you find just the right one for your business. 

An automated cloud vulnerability scanner allows you to be vigilant without losing time. You can create a secure cloud environment without compromising on the speed of operations.

How does a cloud vulnerability scanner work?

A cloud vulnerability scanner is a tool that automates the process of identifying vulnerabilities in cloud-hosted applications.

The scanner probes into the target system by sending certain requests and monitors the responses and compares those responses with details from a vulnerability database. If these responses signal an anomaly, the scanner flags the issue and reports it.

A cloud vulnerability scanner essentially performs the scans in the cloud, hence your servers remain stress-free and your business uninterrupted. It helps you address a number of tricky security-related issues such as security misconfiguration, unauthorized access, insecure interfaces, and account hijacking.

Cloud vulnerability scanning in 4 steps

Planning and scoping the scan:

In this stage, you will need to determine the scope of the scan. This includes identifying which cloud-based assets need to be scanned and setting the frequency of scanning.

This step is crucial for cloud vulnerability scans as the policies set by cloud providers have to be taken into consideration before proceeding with the scan.

Vulnerability scanning:

In this stage, the scanner will identify vulnerabilities in your cloud-hosted application.

Reporting:

In this stage, the scanner will generate a report that details the findings of the scan. The vulnerability assessment report usually includes a list of all the detected vulnerabilities categorized by severity.

Other than that, the test cases used in the scan are also mentioned in the report along with some guidance to fix the issues.

Remediation:

Your developers use the suggestions to fix the most critical vulnerabilities first and work their way down the list according to priority. With some cloud vulnerability assessment providers, you can get expert help from security professionals.

7 features you should look for in a cloud vulnerability scanner

Cloud vulnerability scanning is a little different from website scanning as the scanner needs to support the cloud infrastructure, and some other factors like cloud security policies and guidelines come into play. You need to make sure that you get the right tool on the first go. Here are some features that will help your business in the long run.

Supports GCP, AWS, & Azure

Your scanner should support all the major cloud providers. This will allow you to scan for vulnerabilities across different cloud environments and get a comprehensive view of your application’s security posture.

Optimized for security policies set by the cloud provider

The cloud provider that you use will have a set of security policies in place. The scanner should be able to adhere to those policies so that you don’t have to worry about any compliance issues.

Scanning in the cloud so as not to stress the servers

As mentioned earlier, automated vulnerability scanners for the cloud perform the scans in the cloud. This means that your servers don’t have to bear the brunt of the scan and can continue working without any hiccups.

CI/CD integration and continuous scanning

The scanner should be able to integrate with your CI/CD pipeline so that you can automate the scans. This way, you can ensure that your application is scanned for vulnerabilities at regular intervals.

Compliance-specific scans

Depending on the industry that you’re in, you might have to comply with certain regulations. The cloud vulnerability scanning tool should be able to perform compliance-specific scans so that you can be sure that your application is up to the mark.

Detailed reporting with video PoCs

You should get a detailed report that includes all the information that you need about the vulnerabilities. In addition to that, the report should also have video PoCs so that you can see how the exploit works.

Remediation support

It’s not enough for the cloud security scanner to just identify the vulnerabilities. The scanner should also provide you with guidance on how to fix the issues so that you can remediate them as quickly as possible.

Now that you know what to look for in a cloud vulnerability scanner, it’s time to take a look at some of the best tools on the market.
