Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Scanning for cloud-based vulnerabilities is an essential cybersecurity practice in the tech world.

Network operators deploy basic security measures when managing a network, but some hidden vulnerabilities can be difficult to detect. Hence, the need for automated cloud security scans arises.

Tech enthusiasts are expected to be able to perform basic vulnerability scanning of the cloud environment. This process starts with learning about cloud security scanning tools that can help automate the detection of cloud vulnerabilities on a network.

Several vulnerability scanners are available at little to no cost, but it is essential to know the most efficient ones.

What is a Vulnerability Scanner?

A Vulnerability Scanner is a software tool designed to examine applications and networks for misconfiguration and security flaws automatically. These scanning tools perform automated security tests to identify security threats in a cloud network.

In addition, they have a constantly updated database of cloud vulnerabilities that allows them to conduct effective security scanning.

How to Select the Right Vulnerability Scanner

It is essential to use a suitable vulnerability scanner for cloud security. Many vulnerability scanning tools are available on the internet, but not all will offer what cloud security testers are looking for in automated vulnerability scanners.

So, here are some factors to look out for when selecting a vulnerability scanning tool.

Select a vulnerability scanner that:

  • scans complex web applications
  • monitors critical systems and defenses
  • recommends remediation for vulnerabilities
  • complies with regulations and industry standards
  • has an intuitive dashboard that displays risk scores

It is essential to compare and review tools used in scanning and testing cloud vulnerabilities. They offer unique benefits that ensure system networks and web applications run smoothly and are safe for use in organizations and private businesses.

Vulnerability scanning tools offer cloud monitoring and security protection benefits such as:

  • Scanning systems and networks for security vulnerabilities
  • Performing ad-hoc security tests whenever they are needed
  • Tracking, diagnosing, and remediating cloud vulnerabilities
  • Identifying and resolving wrong configurations in networks

Here are the top 5 vulnerability scanners for cloud security:

Hence, Aqua Cloud Security devised a comprehensive approach to prevent data breaches.

Qualys Cloud Security

Qualys Cloud Security is an excellent cloud computing platform designed to identify, classify, and monitor cloud vulnerabilities while ensuring compliance with internal and external policies.

This vulnerability scanner prioritizes scanning and remediation by automatically finding and eradicating malware infections on web applications and system websites.

Qualys provides public cloud integrations that allow users to have total visibility of public cloud deployments.

Most public cloud platforms operate on a “shared security responsibility” model, which means users are expected to protect their workload in the cloud. This can be a daunting task if done manually, so most users will rather employ vulnerability scanners.

Qualys provides complete visibility with end-to-end IT security and compliance with hybrid IT and AWS deployments. It continuously monitors and assesses AWS assets and resources for security issues, misconfigurations, and non-standard deployments.

It is the perfect vulnerability scanner for scanning cloud environments and detecting vulnerabilities in complex internal networks.

Its features include automated cloud vulnerability discovery, detecting and preventing threats, and continuous runtime protection, including EDR for cloud workloads and containers.

Furthermore, it allows web developers to build and run web applications knowing they are fully protected from a data breach. As a result, when threats are hunted and eradicated, cloud applications will run smoothly and faster while working with the utmost efficiency.


Vulnerability scanners are essential for cloud security because they can easily detect system weaknesses and prioritize effective fixes. This will help reduce the workload on security teams in organizations. Each of the vulnerability scanners reviewed in this guide offers excellent benefits.

These vulnerability scanners allow users to perform scans by logging into the website as authorized users. When this happens, it automatically monitors and scans areas of weakness in the systems.

It also identifies any form of anomalies in a network packet configuration to block hackers from exploiting system programs. Automated vulnerability assessment is very crucial for cloud security services.

So, vulnerability scanners can detect thousands of vulnerabilities and identify the actual risk of these vulnerabilities by validating them.

Once these have been achieved, they then prioritize remediation based on the risk level of these vulnerabilities. All five vulnerability scanners reviewed are tested and trusted, so users do not need to worry about any form of deficiency.

Finally, it is essential to note that vulnerability scanning is different from penetration testing.

Vulnerability scanners discover vulnerabilities and classify them based on their threat level. They correlate them with software, devices, and operating systems that are connected to a cloud-based network. Misconfigurations are also detected on the network.

However, penetration testing deploys a different method that involves exploiting the detected vulnerabilities on a cloud-based network. So, penetration testing is carried out immediately after vulnerability scanning has been done.

Both cloud security processes are similar and focused on ensuring web applications and networks are safe and protected from threats.
