Cloud Security Tools

Introduction :

By seeing the heading of this article, you might be wondering what is all about open source cloud.

It is a service or solution which got developed by using open-source software and technology.


These Cloud Security Tools are useful for any public and private models like SaaS, PaaS, DaaS, etc.

This is completely built and operates through open-source technologies.

In today’s world, 83 percent of enterprises put their workload to the open-source cloud to get the proper data with low cost and time.

It is affordable for every business and employer.

This software adoption can enhance interoperability.

Now let us talk about open-source cloud security, which measures and configures to protect the cloud data.

It also protects customers’ privacy as well as sets the authentication rules for all individual devices and users.

It also helps to filter the traffic where you can configure cloud security to get the exact needs of your business.

These Cybersecurity tools have a large market share where they can meet the requirement of enterprise-grade security software. Many open source security tools available in the market can work like the paid ones. If you are new in the business, you can start your business using the free version.

Many small and mid-size enterprises combine the free and paid open-source Cloud Security tools to improve their organization and protect their network and digital assets.

Here we will discuss the list of open-source cloud security tools that keep your organization safe from hackers.

4. Grapl


This was released the last year in March, and it is a Graph Analytics Platform that is perfect for detection, incident response, and forensics.

It deduces the attacker’s motivation and responds defensively accordingly.

It protects the network in much the same way as a natural defender would, using a graph-based method and an awareness of the network’s full extent.

Grapl is constantly processing the security-related logs, which aids in their transformation into a subgraph.

It marges the subgraphs into Master Graph so that it can reflect the action across the environment.

It executes the analyzers where any suspicious pattern appears, it got discovered in the scry subgraph.

After that, Grapl begins his inquiry.


  • Graph models and analyzes host, process, network traffic, and user account interactions using a graph database.
  • Grapl uses rule-based, anomaly-based, and machine-learning algorithms to detect security concerns and unusual behavior.
  • It allows security teams to monitor and evaluate security occurrences in real-time.
  • It offers incident investigation and forensics tools.

7. Zeek/Bro


It is a network monitoring tool that, like Suricata, looks for out-of-the-ordinary activity on networks.

The suspicious threat activity is also suspected.

Unlike conventional IDS, which is a rules-based engine that can detect the threat with relative ease, this approach is more nuanced.

As a useful network monitoring tool, it records events as they occur and stores them for later review.

It also interacts and understands whatever happened in the network security.

The Zeek programming language can be tailored to meet the unique requirements of any business.

Using just a few operators like AND, OR, NOT, etc., it makes it easier to construct complex logical conditions.


  • Looking at and keeping an eye on network traffic
  • Protocol analysis lets you see a lot of what’s going on in a network
  • Creating and logging events in real time
  • A lot of information is extracted from network traffic
  • A full scripting language for custom research
