Qualys Container Security.

Discover, track and continuously secure containers – from build to runtime.


The Qualys approach [to runtime security] empowers security to follow the container image with built-in instrumentation, enabling visibility and behavior enforcement for running containers across all types of container infrastructure.

Security and risk management leaders must address container security issues around vulnerabilities, visibility, compromise and compliance.

Qualys Container Security Highlights

Visibility into your container projects

Qualys Container Security (CS) gives you a complete visibility of container hosts wherever they are in your global IT environment — on premises and in clouds. It gathers comprehensive topographic information about your container projects — images, image registries, and containers spun from the images. With dynamic, customizable dashboards, you can see your complete inventory and security posture from containers to hosts.

Security for the entire DevOps pipeline

Containerized application development is an easy and open process, but it has a downside: The often inadvertent use of third-party software components that have vulnerabilities. With Qualys CS, security teams can enforce policies to block the use of images that have specific vulnerabilities, or that have vulnerabilities above a certain severity threshold. Developers can do continuous vulnerability detection and remediation in the DevOps pipeline by deploying plugins for CI/CD tools like Jenkins or Bamboo, or via REST APIs.

Threat identification, impact assessment and remediation prioritization

By the nature of their deployment, containers have an increased surface area. With Qualys CS, you can search for images in your environment that have high-severity vulnerabilities, unapproved packages, and older or test release tags. You can then assess their impact by identifying all containers — active or dormant — that use the unapproved, vulnerable images. Qualys CS helps you determine if these images are cached on different hosts, and identify all the containers on exposed vulnerable network ports running with privileges, which could lead to attacks.

Container Runtime Security

Qualys CS extends its container security capabilities to the runtime phase of deployment with its add-on Container Runtime Security (CRS) feature. With CRS, you get full, granular visibility into running containers, as well as the ability to enforce policies that govern containers’ behavior. As a result, CRS lets you immediately detect and act upon container behavior that violates security best practices specified by the security teams.

Discover and inventory container assets

Qualys Container Security provides centralized, continuous discovery and tracking for containers and images. Deploy Qualys’ new native container sensor as a ‘side-car’ container on the docker hosts across build, registry or active deployments located on premises or clouds.

  • Provide users a quick overview of inventory via pre-built dashboards, and personalize or build your own with custom widgets.

  • Get a comprehensive topographic information of the container environments: images, registries, associated containers (both active and dormant), and hosts.

  • View comprehensive metadata for every image including labels, tags, installed software, layers and the association information.

  • View comprehensive metadata for every container, including environment variables used during deployment, services, users, network information, exposed ports, privileged status, and association information to other containers built off the same parent image, in addition to the host or pod they are on.

  • Use smart filters for quick lookup based on all the attributes, save searches and download search results in various formats such as CSV and PDF.

Perform container-native vulnerability analysis

Qualys CS provides wide coverage and high accuracy vulnerability scanning of images by understanding how all of an image’s layers work in unison. This allows security analysts to rapidly analyze the real threats and focus on remediation, rather than wasting time clearing false positives which are prevalent in results from other container scanning products.

  • Get comprehensive coverage, from standard Linux OS distributions to container-centric OSes (like CoreOS and Alpine), applications (like NGINX, PostGres, mySQL, Redis and MongoDB), and programming languages (like Python, NodeJS, RubyGems, GoLang and Java).

  • Run vulnerability scans on images and running containers, and obtain detailed reports of vulnerable software with patchable version information.

  • Identify the composition of the image using layer details gathered by Qualys CS.

Vulnerability analysis in DevOps pipeline

Qualys CS features a vulnerability analysis plug-in for CI/CD tool Jenkins, and soon for other CI/CD tools including Bamboo, TeamCity, and CircleCI. You can download the plugins directly from within the container security module. With Qualys CS, security teams can participate in the DevOps process to gate vulnerable images entering the system, while developers get actionable data to remediate vulnerabilities.

  • Configure policies for preventing vulnerable images from entering the repositories. Set policies based on criteria such as vulnerability severity, and specific QIDs.

  • Review from within the plug-in a summary of the build with its vulnerabilities, information on patchable software and fixed versions, and image layers where it is present.

Detect and block drifting runtimes

Container infrastructure is immutable in nature, which means containers need to be identical to the images they are baked from. With Qualys CS, you can detect containers that break this immutable behavior, and understand if there are unapproved executions and malicious events happening in the running containers.

  • Detect drifting containers by vulnerabilities, software packages and configuration.

  • Get a complete understanding of the anomaly via a granular classification of rogue vulnerabilities and software packages.

Monitor and block behaviors in running containers

Containers must be identical to the images they are generated from. When containers deviate from their parent images, it can be a sign that they have security or compliance flaws, creating a risk for your organization. With Qualys CS’ add-on Container Runtime Security (CRS) feature, you can monitor, allow or block behaviors inside running containers, based on pre-defined policies.

  • Easily add a lightweight security instrumentation to your container images in your build pipeline with policies to govern their runtime behavior around file access, network communications and process activity

  • Get full visibility into running containers through continuous collection of data about their file access, network communications and process activity

  • Choose to monitor, allow or block specific container behavior based on policies. Policies can be created from scratch, chosen from the built-in policy library or generated automatically from learnt container behaviors

  • Dynamically update the policies applied to a running container without having to re-start it

  • Get alerted instantly about runtime containers that violate security and compliance policies

  • See container runtime policy events and behavioral events on your Qualys dashboard and drill down for details

  • Protect running containers everywhere – on premises, in private clouds, or in container-as-a-service (CaaS) public clouds

New Qualys 'Container Sensor'

Qualys has developed a native sensor available as an image for Docker-based containers. It’s deployed as a ‘side-car’ unprivileged container on docker hosts.

  • Container Sensor supports Docker containers running on Linux, and deployable across Kubernetes, Docker Swarm and other orchestration environments.

  • You can generate daemon sets for Kubernetes, and download sample templates for Docker Swarm and other orchestration environments.

  • Container Sensor is self-updating and can be configured to communicate over proxies.

REST APIs and Integrations

Qualys CS’s complete features are available as REST APIs. These are clearly documented with examples and easy test options in Swagger, enabling DevOps teams to integrate security across their CI/CD tool chain. You can further automate the aggregation of security data into SIEMs and ticketing processes with purpose-built connectors for Splunk and ServiceNow (coming soon).
