ArcSight vs Qualys: What are the differences?

# Key Differences between ArcSight and Qualys

ArcSight and Qualys are both popular cybersecurity solutions, but they have key differences that differentiate them in terms of functionalities and use cases.

1. **Scope of Functionality**: ArcSight is primarily a security information and event management (SIEM) platform that focuses on log management and monitoring, whereas Qualys specializes in vulnerability management and assessment, providing tools for identifying and prioritizing security risks in networks, applications, and systems.

2. **Deployment Model**: ArcSight is typically deployed on-premises, requiring organizations to invest in hardware and infrastructure to run the platform, while Qualys is a cloud-based solution, offering scalability and flexibility without the need for on-site hardware.

3. **Focus on Compliance**: Qualys places a strong emphasis on compliance scanning and reporting, helping organizations adhere to regulatory requirements such as PCI DSS and HIPAA, whereas ArcSight is more tailored towards threat detection and incident response.

4. **User Interface and Ease of Use**: Qualys is known for its intuitive user interface and user-friendly design, making it easier for security teams to navigate and utilize the platform effectively. In comparison, ArcSight can be more complex and require specialized training for optimal utilization.

5. **Integration Capabilities**: ArcSight provides extensive integration capabilities with other security tools and systems, enabling organizations to create a comprehensive security ecosystem, while Qualys focuses more on its own suite of tools and services, limiting the integration options with third-party solutions.

6. **Cost Structure**: ArcSight tends to have a higher upfront cost due to its on-premises deployment and hardware requirements, while Qualys operates on a subscription-based model, offering more predictable and scalable pricing options for organizations of varying sizes.

In Summary, ArcSight and Qualys differ in their core functionalities, deployment models, compliance focus, user interface, integration capabilities, and cost structure.
