Qualys, Inc. (NASDAQ: QLYS)

Qualys, Inc. operates as a leading provider of cloud-based information technology (IT), security, and compliance solutions. The company's core business revolves around delivering an integrated suite of solutions designed to help organizations identify, manage, and protect their IT and operational technology (OT) assets across various environments, including on-premises, endpoints, cloud, containers, and mobile. Qualys' offerings are particularly relevant in an era where IT infrastructures are increasingly complex and globally distributed, with organizations relying on a myriad of interconnected systems and networks. The company's solutions are aimed at addressing the growing IT, security, and compliance complexities and risks that are amplified by the rapid adoption of cloud computing, containers, and serverless IT models, as well as the proliferation of geographically dispersed IT assets.

Qualys generates revenue primarily through a software-as-a-service (SaaS) model, offering renewable annual subscriptions for its cloud solutions. The company's revenue streams are driven by a suite of products and services collectively referred to as Qualys Cloud Apps. These solutions help customers detect, measure, prioritize, and remediate cyber risks across their IT infrastructures. Qualys' customer base is diverse, ranging from some of the largest global organizations to small businesses, with over 10,000 customers worldwide, including a majority of the Forbes Global 100. The company's revenues have shown consistent growth, increasing to $669.1 million in 2025 from $607.6 million in 2024 and $554.5 million in 2023.

• Asset Management: This segment includes solutions like Cybersecurity Asset Management (CSAM) and Enterprise TruRisk Management (ETM). CSAM leverages the Qualys cloud platform to continuously inventory known and unknown assets, discover installed applications, and assess the health of the attack surface. ETM provides a unified view of cyber risk across an organization's entire attack surface, including on-premises infrastructure, cloud environments, and applications.

• Vulnerability and Configuration Management: Key products in this segment include Vulnerability Management, Detection and Response (VMDR) and Total Application Security (TotalAppSec, TAS). VMDR enables organizations to automatically discover assets, inventory hardware and software, classify and tag critical assets, and continuously assess these assets for vulnerabilities. TAS focuses on detecting vulnerabilities and misconfigurations in web applications and APIs, scaling to thousands of scans and integrating with other systems for early detection of issues within DevOps environments.

• Risk Remediation: This segment features solutions like Patch Management (PM) and Custom Assessment and Remediation (CAR). PM provides automated patch deployment capabilities for various software, correlating vulnerabilities with the right remediation actions. CAR enables security architects to create custom scripts and automation for assessing and remediating threats across global hybrid environments.

• Threat Detection and Response: The Multi-Vector Endpoint Detection and Response (EDR) solution is a key offering in this segment. It provides comprehensive visibility to the entire attack chain, from prevention to detection to response, by unifying different context vectors and leveraging a powerful backend for accurate assessment, detection, and response.

• Compliance: Solutions in this segment include Policy Audit (PA) and File Integrity Monitoring (FIM). PA automates security configuration assessments across IT systems, providing real-time visibility into compliance status and helping prevent configuration drift. FIM logs and tracks file change events, providing customers with a way to achieve centralized visibility of system activity and comply with change control policy enforcement.

• Cloud Security: TotalCloud (TC) is a Cloud-Native Application Protection Platform (CNAPP) that provides an integrated suite of security capabilities designed for multi-cloud environments. It offers complete visibility and cyber-risk exposure assessment across cloud assets, enabling continuous discovery and monitoring of the cloud landscape to identify risks and maintain compliance.

Qualys holds a strong position within the IT security and compliance industry, competing with a broad array of established and emerging vendors. Key competitors include CrowdStrike, Palo Alto Networks, Rapid7, and Tenable Holdings, as well as privately held security providers such as Invicti, Tanium, and Wiz. The company's competitive advantages lie in its comprehensive cloud-based solutions, which detect, measure, prioritize, and remediate cyber risks delivered on a single platform. Qualys' offerings are designed to be easily and rapidly deployed on a global scale, enabling faster implementation and lower total cost of ownership compared to traditional on-premise enterprise software products. The company's solutions are also known for their real-time visibility, seamless scaling, and up-to-date resources, which include one of the largest knowledge bases of vulnerability signatures in the industry.

Qualys serves a broad range of customers, including enterprises, government entities, and small and medium-sized businesses across various industries such as education, financial services, government, healthcare, insurance, manufacturing, media, retail, technology, and utilities. The company's solutions are marketed and sold through a combination of direct sales teams and a network of channel partners, including security consulting organizations, leading cloud providers, managed service providers, and resellers. Qualys' customer base is diverse, with no single customer accounting for more than 10% of its revenues. The company's solutions are particularly relevant for organizations looking to simplify their security stacks and regain unimpeded visibility across their IT environments.
