Qualys vs Zscaler: What are the differences?

Introduction

Qualys and Zscaler are both leading cybersecurity companies that provide solutions for organizations to protect their networks and assets from various threats. While they both focus on security, there are key differences between Qualys and Zscaler that set them apart in terms of their offerings and approach.

1. Cloud-based vs. On-premises:

Qualys is primarily a cloud-based solution, offering a suite of cloud-based security and compliance solutions that can be accessed and managed through a web browser. On the other hand, Zscaler offers a combination of cloud-based and on-premises solutions with a focus on delivering security through their cloud-native platform.

2. Scope of Security Services:

Qualys provides a comprehensive range of security services that cover vulnerability management, threat intelligence, web application scanning, and compliance management. Zscaler, on the other hand, offers a broad range of security services that primarily focus on web security, including secure web gateways, firewall as a service, data loss prevention, and secure access service edge (SASE) solutions.

3. Threat Detection and Prevention:

Qualys emphasizes vulnerability management and threat detection through continuous security monitoring and assessment of assets. They provide real-time visibility into vulnerabilities and help organizations prioritize and remediate these risks. On the other hand, Zscaler focuses on threat prevention through its cloud-native security platform, which includes advanced threat protection, sandboxing, and encryption to block malicious activities and prevent data breaches.

4. Network Security vs. Endpoint Security:

Zscaler's focus is primarily on securing networks and ensuring safe internet access for all users, regardless of their location or device. Their cloud-native platform provides secure connectivity and policy enforcement, protecting users from threats before they reach the network perimeter. In contrast, Qualys also offers endpoint security solutions, including cloud-based agents and detection capabilities, to protect endpoints against malware, malicious activities, and data breaches.

5. Data Centers and Global Infrastructure:

Qualys operates multiple data centers across the globe to ensure the availability and performance of their cloud-based security services. They have a global infrastructure that enables customers to access and manage their security solutions seamlessly. On the other hand, Zscaler has a highly distributed global cloud network with numerous data centers strategically located worldwide, allowing them to deliver security services to users wherever they are.

6. Integration and Partnerships:

Both Qualys and Zscaler offer integration capabilities with third-party solutions to enhance their security offerings. However, Qualys has a broader range of integrations with popular security tools and platforms, enabling customers to leverage existing investments in security technologies and streamline their overall security operations. Zscaler, on the other hand, has strong partnerships with various technology providers, such as cloud service providers and network security vendors, to expand their security capabilities and deliver integrated solutions.

In summary, Qualys is a cloud-based cybersecurity company focusing on vulnerability management and comprehensive security services, while Zscaler is a cloud-native platform offering a range of web security solutions with a focus on threat prevention and network security. Qualys covers endpoint security as well and has a wider range of integrations, while Zscaler emphasizes secure internet access and has a highly distributed global cloud network.
