The evolution of cloud security

The cloud presents an opportunity for security system providers to cut costs by hosting their software and providing it to customers on the SaaS model. However, as more system creators make the same switch, security scanning becomes more complicated. A security tool no longer has the boundaries of a network to work within.

The first phase of cloud security development was to create tools that can monitor both on-premises and cloud-based systems. This strategy suits most businesses that now have to work with packages in both areas. So, there are now cloud-based SIEMs and XDRs that monitor on-premises systems and cloud packages. User access controls can be implemented by a Zero Trust Architecture (ZTA) and Cloud Infrastructure Entitlement Management (CIEM).

The proliferation of SaaS systems, mobile apps, and online services in websites means that there is now a large market for cloud security tools that provide protection for those systems. That is, security that is marketed to the owners of those cloud and Web systems rather than to their customers. This has created a new field of tools, which include Cloud Security Posture Management (CSPM), which is a cloud version of a vulnerability scanner, and Cloud Workload Protection Platforms, which provide anti-virus and intrusion detection for cloud systems. A bundle of these services is called a Cloud-Native Application Protection Platform (CNAPP).

Developers and operators of framework,s APIs, and other Web services needs Application Security Testing systems, commonly implemented as Static Application Security Testers (SAST) and Dynamic Application Security Testers (DAST).

  • Cloud Workload Protection Platform: Live security monitoring for cloud assets
  • Compliance Auditing: Calibrates controls to specific standards

Why do we recommend it?

Datadog Cloud Security Management is at the cutting edge of the rapidly developing field of cloud security. It offers the main cloud system protection tools of Cloud Security Posture Management (CSPM) for exploit detection and system hardening, and a Cloud Workload Protection Platform (CWPP) for constant vigilance against malware and manual attacks.

The tool explores all of the cloud services that you register in the monitoring system and looks for components and related subscriptions. This generates a dependency map and then the system checks each of these units individually and as a group. The system looks at how these modules connect and exchange data, which could identify a point of security weakness.

The Cloud Workload Security module is the other package in the Cloud Security Management service. This option is a live security service, similar to an anti-malware package on a computer. So, you have two options – scan for vulnerabilities and look out for attacks.

The two packages of Cloud Security Management are not mutually exclusive – you can subscribe to both. Cloud platforms might serve different business departments and even have separate support times looking after them. The Datadog platform allows the administrator to set up multiple user accounts, so a collaborative effort can be facilitated to resolve security problems and threats.

Who is it recommended for?

Like any cloud security system, this package is of interest to businesses that manage SaaS platforms and services to other cloud system owners, such as frameworks and APIs. The system is useful for DevOps teams and particularly so if combined with the code profiling and distributed tracing functions of the Datadog APM package.

11. Rubrik

Rubrik dashboard

Sometimes, no matter how hard you try to protect your data, you will find that it just isn’t enough. And sometimes, disaster does strike and you lose your data.

But, that doesn’t mean you have to close shop and slink away into oblivion. On the contrary, you should have a backup and restore system that you can rely on to protect your data and have you back on your feet again in the shortest amount of time – regardless of the amount of data lost.

Key Features:

  • Cloud Security Posture Management: Discovers security weaknesses before hackers do
  • Backup and Recovery: Protection for cloud-stored data
  • Mirrored Backup Repositories: Immutable storage

12. Orca Security

Orca Security alerts

Orca Security is a SaaS tool that delivers in-depth visibility into AWS, Azure, and GCP. It replaces legacy vulnerability assessment tools, Cloud Security Posture Management (CSPM), and Cloud Workload Protection Platforms (CWPP).

Key Features:

  • Protection for Cloud Platforms: AWS, Azure, Alibaba Cloud, and Google Cloud Platform
  • Sensitive Data Protection: Discovers, categorizes, and maps personally identifiable information
  • Cloud Security Posture Management (CSPM): Preventative security scanning

Why do we recommend it?

Orca Cloud Security Platform provides vulnerability scanning for cloud systems provided by AWS, Azure, Alibaba Cloud, and Google Cloud Platform. It can also scan Kubernetes containers. The service isn’t an occasional on-demand scanner – it handles the alerts that your cloud services emit and organizes them into a prioritized list.

This is a completely agentless tool and requires no installation. It involves a simple three-step process to connect and account and start discovery, monitoring, and assessing all cloud assets, regardless of platform, network, or operating system. Even paused or stopped machines are discovered.

Once connected, Orca scans a read-only view of cloud assets that includes cloud configuration, operating systems, applications, and data.  The tool then detects vulnerabilities, malware, misconfigurations, lateral movement risk, weak (or leaked) passwords, and high-risk data such as Personally Identifiable Information (PII). Once the vulnerability information is compiled it is then prioritized based on the risk it poses.

This tool is an ideal tool for large enterprises as well as “born in the cloud” companies in industries such as SaaS, FinTech, Internet, media, ad tech, and pure-cloud service delivery.

Orca treats a cloud network as an interconnected web of assets. Should it find any ambiguities or errors, it can be configured to push informative alerts to Slack (or any other third-party collaboration platform where the admins hang out) and include each alert’s precise path or triggering point to help with a quick resolution.

Who is it recommended for?

This service doesn’t cover all cloud platforms. For example, there is no mention of Oracle Cloud or SaaS systems, such as Salesforce or Microsoft 365. The platform offers a number of modules and you will need to understand cybersecurity terminology in order to pick the right services for your business.

Splunk Enterprise Security protocol intelligence

Splunk Enterprise Security is a software platform for machine data analysis that enables customers to gather real-time Operational Intelligence on their digital investment.

Key Features:

  • On-Premises Software: A cloud-based version is also available
  • A SIEM Service: Reads through activity logs
  • False-Positive Alerting Reduction: Risk-based alerting

Why do we recommend it?

Splunk Enterprise Security is a SIEM tool and is one module in a platform of security systems that can be hosted on your server or accessed on a cloud platform. This package collects log messages from all of your assets and searches through them for threats. The service can extract status logs from cloud platforms.

This security tool enables admins to search, analyze, and visualize the data gathered from all components of an IT infrastructure including data from websites, applications, sensors, devices, and more which it then stores in a searchable format.

Splunk is an analytics-driven Security Incident and Event Management (SIEM) solution that uses actionable intelligence and advanced analytics to combat threats. It detects, investigates, and responds to these threats in real-time allowing for secure and no-risk operations.

Splunk Enterprise Security consists of a group of security modules known as the Splunk Security Operations Suite which includes two other packages – Splunk User Behavior Analytics, which draws on user and entity behavior analytics to stop as-of-yet unknown threats and Splunk Phantom, a tool to automate and coordinate the subsequent responses to them.

Splunk is the security platform that enables admins to perfect their security operations and reduce associated risks. From this platform, they can streamline their entire security stack, minimize unplanned downtime, and explore and visualize business processes for increased transparency.

The information that is gathered includes machine data from multi-cloud or on-premises installations that are displayed in one unified view for a quicker response. Admins can then quickly and effectively resolve the issues.

An interesting feature from Splunk is the Advanced Threat Investigation which uses advanced detection and investigative controls to detect and investigate abnormal activity that is usually associated with compromised systems.

Who is it recommended for?

This package is one option for businesses that are looking for SIEM solutions. There are other SIMs on the market and you should assess the Splunk option alongside other candidates. One of the signature features of the Splunk service is that is able to process large volumes of data very quickly.


  • User and Entity Behavior Analytics: Looks for unusual behavior per user account and per endpoint

14. Zscaler

Zscaler ZIA 6.0 Web Overview Dashboard

With Zscaler we have a comprehensive suite of security services that are also delivered from the cloud. It is the ideal tool for protecting users who use cloud applications as would be the case in clients of an On-Demand Software service provider.

Key Features:

  • A Menu of Edge Services: All modules operate from the cloud
  • Creates a Virtual WAN: Secures connections between users and cloud services
  • Firewall Service: Block malware and intruders from getting cloud to your cloud assets

Why do we recommend it?

Zscaler provides a toolkit of security measures that can be assembled in different combinations to provide different security strategies. It hottest option at the moment is the creation of a Zero Trust Access system. You can also implement SASE with this service.

Businesses that use this tool can protect their users by routing Internet traffic through the Zscaler Security Cloud, which is distributed across more than 100 data centers worldwide. The company’s direct-to-cloud architecture connects users to the nearest data center for an overall faster UX.

This method also cuts costs for their clients because they don’t need to purchase and manage their own network security software or devices.

One of the company’s two main services is Zscaler Internet Access (ZIA), which acts as a gateway between users and the Internet. ZIA securely connects users to externally managed applications – be they applications or Internet hosts, and regardless of device, location, or network.

The ZIA service also inspects encrypted and unencrypted Internet traffic in-line, looking for malware and advanced threats while also helping prevent corporate data leakage.

The other service, Zscaler Private Access (ZPA), offers authorized users with fast and secure access to internally managed applications hosted in enterprise data centers or in the cloud. Unlike a Virtual Private Network (VPN), which is used to connect users to a corporate network, ZPA connects a user to an application without involving the network, resulting in more secure connectivity.

Who is it recommended for?

Zscaler is affordable and accessible for any size of business. However, it doesn’t provide a single out-of-the-box security solution and you have to know a thing or two about cybersecurity and networking in order to get the most out of the platform.


  • Access Rights Management: System access accounts flow through to application access
  • SSL Offloading: Enables the firewall to unpack and inspect packet contents
  • Traffic Management: Offers WAN optimization


  • A Complicated Solution: This package is best suited for multi-site hybrid networks that also have remorse workers

Choosing a cloud security tool

While keeping the security of a cloud computing architecture can be done using several applications to take care of endpoints, servers, and networks, we can all agree the best solution would be one that covered the entire setup from end to end.

With that in mind, we can say Trend Cloud One – Workload Security is the best of the best cloud security tool with Splunk Enterprise Security and Orca Security following close behind.

Cloud security tools FAQs

What are security issues related to using cloud-based file management tools?

There are two main security issues when working with cloud-based file management tools: protection for data at rest and protection for data in motion. The files held on your cloud server didn’t originate there. Even if your cloud service includes productivity tools to create the files, there will still be a transfer of characters from the creator’s computer to the cloud server. So, if a user types the contents of the file, the connection between the user’s device and the cloud server needs to be encrypted and remote access to the server needs thorough authentication. If the file is created locally and then transferred to the cloud server, the same level of protection also needs to be applied. The files stored on the cloud server need to be protected with encryption to control access and the people allowed access should be identifiable with secure credentials. 

What are the four areas of cloud security?

One definition of cloud security defines four areas to consider — other theorists define three or even five categories. The four areas are:

  • Visibility and compliance – Know where everything is and what its value or sensitivity is
  • Compute-based security – This is provided by vulnerability management and a SIEM
  • Network protection – Firewall-as-a-Service, Secure Access Service Edge (SASE), or Zero Trust Access
  • Identity security – Identity and access management (IAM)
