What is a Cloud Workload Protection Platform?
A cloud workload protection platform (CWPP) is a security solution that provides continuous threat monitoring and protection for cloud workloads across different types of cloud environments. CWPP protects cloud workloads running on virtualized private servers and public cloud infrastructure, on-premises data centers, and serverless workload platforms like AWS Lambda.
Cloud workload security, also known as cloud workload protection, is a set of security controls aimed at protecting cloud-based workloads.
It’s this comprehensive protection that makes CWPP a cut above other cybersecurity solutions. As Gartner explains, CWPP takes on the role of a guardian for your workloads “regardless of location.”

What is a cloud workload?
A cloud workload is a collection of resources that are used to execute a specific business process or function. These resources can include virtual machines, containers, databases, applications, and data. Cloud workloads can be deployed on a variety of cloud platforms, including public, private clouds, and hybrid cloud environments.
How does CWPP work?
CWPP combines machine learning, behavioral analysis, and automated defenses, all working together to ensure your cloud workloads are secure no matter where they run. It carefully examines tiny patterns and variations, trying to understand what's normal for your system. With this understanding, it is able to spot anything unusual that may be a threat. It can instantly raise a red flag and activate response playbooks to stop a potential security threat before it causes any real damage.
The first step for a CWPP is to scan workloads and find any security vulnerabilities. It then suggests remedial action to deal with these vulnerabilities. Finally, once known threats are neutralized, CWPP also keeps an eye out for threats that may arise in production, or during runtime.
From an operational point of view, CWPP makes life easy for cybersecurity professionals, as it gives them a single centralized vantage point from which to view their entire technology estate—whether cloud, hybrid, or on-premises. Rather than switching context between multiple security tools, cybersecurity professionals gain added focus on the key issues that need to be addressed across the entire landscape of their software systems.
This Wiz Research team has found that 58% of cloud environments have at least one publicly exposed workload with a cleartext long-term cloud key stored in it. This greatly increases the risk of lateral movement in the VPC and between VPCs.
CWPP Benefits
Let’s explore the key benefits through which CWPP empowers organizations to fend off potential vulnerabilities across your technology stack end-to-end:
Ruthless visibility: CWPP gives you enhanced visibility of cloud-based applications so your security teams get to scrutinize activities, identify abnormalities, and take preemptive actions against threats with surgical precision.

Key features to look for in a CWPP
With the number of cybersecurity solutions available, you need a handy list of essential features to look for in a capable CWPP solution. You'll have to carefully scrutinize each option and consider compatibility and scalability before making your pick.
Here are the top must-haves for your CWPP platform:
Runtime protection: The heart and soul of your CWPP lies in its ability to provide unwavering real-time protection. This means that threats attempting to infiltrate your cloud workloads are swiftly detected and neutralized without any delay. With runtime protection in your CWPP toolkit, you can rest assured that potential damage is mitigated and your operations continue smoothly without any disruptions.
Real-time threat detection and incident response: A CWPP can detect known and unknown threats and suspicious activity across your cloud environments, including remote code execution, malware, crypto-mining, lateral movement, privilege escalation, container escape, and more.
Agentless scanning: If your CWPP solutions support this, you can say goodbye to the hassle of agent deployment and enjoy the benefits of agentless scanning across your entire cloud stack. Agentless scanning simplifies cloud security management, as it’s a lot easier to get started with. Plus, it's resource-friendly, making sure your cloud environment remains optimized at scale.
Vulnerability management: A CWPP's vulnerability assessment should prioritize vulnerabilities based on their severity, exploitability, and the value of the assets they affect. This helps organizations focus on the vulnerabilities that pose the greatest risk to their organization.
CI/CD integration: For fortified cloud security at every stage of your software development life cycle (SDLC), seamless integration of your CWPP into the continuous integration and continuous deployment (CI/CD) pipeline is a must. By weaving security measures into every step of your developmental process, you create applications that stand strong against potential vulnerabilities.
Compliance Assessments: A complete CWPP solution should also continuously assess your workloads across all compliance frameworks. The results should be compiled into a compliance heatmap to allow security teams to quickly determine areas of focus.

CWPP vs CSPM
In general, CWPPs and CSPMs are complementary tools that can be used together to provide a comprehensive approach to cloud security. CWPPs can help to protect cloud workloads from attacks, while CSPMs can help to prevent misconfigurations that can make cloud workloads more vulnerable to attack.
Example use cases for CWPP
Detecting fileless attacks targeting workloads
The Wiz research team recently discovered a fileless attack named PyLoose, which targets cloud workloads using a Python script that leverages the Linux fileless technique memfd. Fileless attacks, like PyLoose, are particularly elusive due to their reliance on memory-based execution and the Linux memfd feature, making them harder to detect, investigate, and attribute.
Fortunately, the Wiz runtime sensor was able to detect malicious behavior, such as payload delivery and execution, unfolding inside the workload. Below is an example detection from the CWPP:
Check out the research team's blog below to get a step-by-step analysis of how the Pyloose attack unfolded, and how it was detected.

An overprivileged user restricted
Imagine you see service A accessing another high-priority service B, which it doesn’t usually access. You wonder if something is amiss. Your CWPP is able to give you insight into each service, its permissions, and how you can secure them.
You use your CWPP solution to dig in and find that service A has read and write access to service B, and it requires read-only access. You have all the information you need to reduce the privileges of service A, and give it a dynamic secret with read-only access to service B the next time. CWPP gives you this crucial context and enables you put the proper access controls in place
Revealing cloud misconfiguration and detecting drift
The effective management of host configurations in today's intricate and sprawling application infrastructures is a complex challenge that can lead to vulnerabilities and misconfigurations. CWPP helps tackle this challenge with custom host configuration rules.
Custom host config rules are like a magnifying glass for the black boxes that often are virtual machines. These rules identify misconfigurations and allow you to zoom in on configuration without having to scope into a specific resource.
Custom host config rules empower users to create tailored logic that is executed during automated, agentless workload scans. This means that manual commands on virtual machines or application files are no longer required, ensuring comprehensive coverage across the entire cloud estate.
Custom rules can also be automatically applied to any new workload and determine if the OS or cloud application is misconfigured. So if over time configuration changes due to user intervention or malicious intent, a CWPP will audit the changes and alert you if there is configuration drift.
CWPP is just one part of the equation
In the ever-evolving cloud landscape, you can't underestimate the importance of CWPPs. With CWPP on your side, you gain extensive visibility and proactive threat detection into your workloads – but cloud security doesn't stop there.
A holistic cloud security strategy involves a combination of cloud solutions including:
CWPP to protect workloads end-to-end
Cloud infrastructure entitlement management (CIEM) to manage permissions at scale
Cloud security posture management (CSPM) for secure management of configuration and resources
Together, this combination of solutions is referred to as a cloud-native application protection platform (CNAPP). Embracing a modern CNAPP solution can help you keep pace with the fast-changing cloud landscape and the complexity of a fragmented technology landscape.
