Enhance Amazon S3 Data Security with Advanced Access Controls and Antivirus Protection
The typical enterprise organization stores high volumes of data in cloud storage services such as Amazon S3– with much of this data being sensitive or otherwise business critical in nature. Particularly for organizations who leverage data lakes built on Amazon S3, the sheer volume of data housed within one (or a few) individual storage resources is staggering. Scaling cloud infrastructure requires implementing proper access controls and comprehensive malware protection. These measures limit exposure to bad actors and unintended user mistakes, protecting against data breaches, system disruptions, and financial losses. Implementing these controls secures the cloud and helps achieve certifications like ISO 27001. Cloud Storage Security Antivirus for Amazon S3 enhances Amazon S3's native features, offering advanced antivirus scanning and malware protection.

PCI DSS v4.0.1-Compliant Financial Data Management
In June 2024, the Payment Card Industry (PCI) Security Standards Council released version 4.0.1 of the PCI Data Security Standards (PCI DSS) detailing numerous best practices which organizations that store and process payment card information should implement. PCI DSS outlines the ways in which compliant organizations must store and process information, including when that data is stored on the cloud. With cloud storage and the popularity of online payments expanding, modern organizations must understand how they can remain compliant and trustworthy to end users and customers. As of April 1st, 2025, these new “best practices” become mandatory and are within scope of audit for continued compliance.
