Monitoring Cloud Files for Changes Without Installing Software
This patent describes a method for checking if files stored in a cloud environment have been changed, by looking at logs from the cloud service instead of installing special software on the cloud servers.
Original patent title: “Agentless file integrity monitoring for data managed by a cloud-based filesystem service”
This patent describes a method for checking if files stored in a cloud environment have been changed, by looking at logs from the cloud service instead of installing special software on the cloud servers. Granted in 2026.
Coverage
What does this patent actually cover?
The patent outlines a system that performs security monitoring in cloud computing environments, especially those without installed monitoring software, known as agentless environments. It works by first identifying a specific file in the cloud that needs monitoring. This file is managed by a cloud-based filesystem service. The system then accesses log data generated by that cloud-based filesystem service, which records any changes to the designated file. Based on this log data, the system performs a file integrity monitoring operation to detect unauthorized modifications. The results of this monitoring are then used to enhance the overall security monitoring of the cloud environment.
The gap
What does this patent NOT cover?
- Does not cover monitoring files stored on traditional, on-premise servers that are not part of a cloud-based filesystem service.
- Does not cover file integrity monitoring systems that require installing a software agent directly onto the compute environment being monitored.
- Does not cover monitoring changes to data that is not managed by a cloud-based filesystem service, such as data directly within a cloud database service.
- Does not cover file integrity monitoring methods that do not rely on accessing log data produced by the cloud-based filesystem service.
- Does not cover detecting file changes if the cloud-based filesystem service itself does not produce relevant log data.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The noveltynoveltyThe requirement that an invention be different from anything publicly known before its priority date.Read more → lies in achieving file integrity monitoring without deploying any additional software agents on the cloud compute environment. Instead, it cleverly reuses the existing log data already produced by the cloud's own filesystem service, turning passive system records into an active security monitoring tool.

Why it matters
The bigger picture
File integrity monitoring is crucial for detecting unauthorized changes to important files, which can indicate a security breach or compliance violation. This patent offers a way to do this in cloud environments without the overhead of installing and managing agents, simplifying security operations and improving coverage for cloud-native applications. It helps organizations meet regulatory compliance requirements by providing an audit trail of file modifications in the cloud.

Market context
Who's building on this
Companies in this space
Major cloud security vendors like Palo Alto Networks (Prisma Cloud), CrowdStrike, and Zscaler are actively developing and integrating agentless security capabilities into their platforms. Cloud providers themselves, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), offer native services that leverage log data for security and compliance, often incorporating similar principles.
Market impact
This approach reduces the operational burden and potential attack surface associated with traditional agent-based security solutions in the cloud. It enables more comprehensive security coverage for ephemeral and serverless cloud assets, which are difficult to monitor with agents. The market has seen a shift towards agentless cloud security solutions, driven by the need for simpler deployment, broader coverage, and better integration with cloud-native services.
