Qualys Cloud Security

Basic Information

Qualys Cloud Security refers to the suite of cloud-based security and compliance solutions offered by Qualys. It is not a single product but a comprehensive platform designed to provide continuous visibility, assessment, and protection across various IT environments, including on-premises, cloud, and mobile assets. The platform integrates multiple security applications to manage cybersecurity and compliance effectively.

• Model: Qualys Cloud Platform (encompasses various modules like VMDR, Cloud Security Assessment, TotalCloud, etc.)
• Version: Continuously updated cloud-based service. Specific version numbers typically apply to individual modules or agents within the platform.
• Release Date: The Qualys Cloud Platform has evolved over many years. The platform itself was established as a pioneer in cloud-based security solutions.
• Minimum Requirements: For the Qualys Cloud Agent, minimum requirements include 512 MB to 1 GB RAM and 200 MB disk space. Hosts must reach the Qualys Cloud Platform over HTTPS port 443.
• Supported Operating Systems: Qualys Cloud Agents support Windows, Linux/Unix (including .rpm, .deb, .txz), macOS, PowerPC, and AIX platforms.
• Latest Stable Version: As a cloud-based platform, updates are continuous. Specific modules within the platform receive regular updates.
• End of Support Date: Not applicable to the platform as a whole due to its continuous service model. End-of-life policies would apply to specific older agent versions or operating systems no longer supported for agent deployment (e.g., Windows XP, Server 2003/SP2, Server 2008/SP1/SP2 for TLS 1.2 support).
• End of Life Date: Not applicable to the platform as a whole. Specific components or older OS versions may have EOL dates.
• License Type: Subscription-based, often with a pay-per-asset charge.
• Deployment Model: Cloud-based service with agents, virtual scanners, and appliances deployed on-premises, at endpoints, in containers, or across various cloud environments.

Technical Requirements

Qualys Cloud Security primarily operates as a cloud-based service, with local components like the Qualys Cloud Agent requiring minimal resources on the host systems.

• RAM: 512 MB for scan-based features (Inventory, Vulnerability Management, Policy Compliance); 1 GB for File Integrity Monitoring and Patch Management.
• Processor: Not explicitly detailed, but generally requires modern processors compatible with supported operating systems.
• Storage: Minimum 200 MB of available disk space for Cloud Agents.
• Display: Not applicable for agent-based components; web-based console requires standard display capabilities.
• Ports: HTTPS port 443 for communication with the Qualys Cloud Platform.
• Operating System: Windows, Linux/Unix, macOS, PowerPC, AIX. Specific versions require TLS 1.2 or later enabled.

Analysis of Technical Requirements

The technical requirements for deploying Qualys Cloud Agents are notably low, making it suitable for a wide range of enterprise assets, including older systems. The primary requirement is network connectivity over HTTPS port 443 to the Qualys Cloud Platform. This minimal footprint ensures that the agent has a low impact on system performance and can be deployed broadly without significant hardware upgrades. The platform's cloud-native architecture offloads most processing and data analysis to the Qualys cloud, reducing local resource demands.

Support & Compatibility

Qualys Cloud Security offers broad compatibility and continuous support as a cloud-native platform.

• Latest Version: Continuous updates are applied to the cloud platform and its various modules.
• OS Support: Extensive, including Windows, Linux/Unix, macOS, PowerPC, and AIX. Specific platform matrix details are available in the Cloud Agent Getting Started Guide.
• End of Support Date: Qualys maintains an end-of-life policy for older operating systems that may no longer support necessary security protocols like TLS 1.2.
• Localization: Information not explicitly detailed in search results, but as a global provider, multi-language support is typical for enterprise software.
• Available Drivers: Not applicable, as it uses agents and cloud services rather than hardware drivers.

Analysis of Overall Support & Compatibility Status

Qualys demonstrates strong support and compatibility across diverse IT environments. The continuous update model of the cloud platform ensures that users always have access to the latest features and security intelligence. Broad operating system support for its Cloud Agents allows for comprehensive coverage of an organization's asset inventory. The emphasis on TLS 1.2 or later highlights a commitment to modern security standards, though this may necessitate updates on very old operating systems. Qualys also offers training and certification programs for its various modules, indicating a commitment to user enablement.
