Security teams running containerized workloads are dealing with a problem that keeps compounding. CVE submissions to the National Vulnerability Database increased 263% between 2020 and 2025, and submissions in the first quarter of 2026 came in nearly one-third higher than the same period a year prior.[1]<\/a> That rate of disclosure does not slow down for teams that are already behind on remediation. It accelerates against them.<\/p>\n

Container environments make this worse in specific, structural ways. Images get built from base layers that carry their own package inventories. Those inventories are scanned once at build time, cleared, and then drift for weeks or months while newly discovered vulnerabilities accumulate silently in production. The CI\/CD pipeline keeps moving. Container instances spin up, do their job, and disappear (often within minutes) without ever being reassessed against the updated state of vulnerability databases<\/a>.<\/p>\n

The result is a persistent gap between what teams believe is secured and what is actually running in their cloud environments. Closing that gap requires more than adding another scanner. It requires an honest evaluation of what specific capabilities a container vulnerability management<\/a> program actually needs, where current approaches fall short, and how to judge what tooling genuinely addresses the problem versus what generates noise at scale.<\/p>\n

This article is written for security leaders and DevSecOps teams doing exactly that kind of evaluation.<\/strong><\/em><\/p>\n<\/div>\n<\/div>\n

\n
\n

Why the Existing Approach Tends to Break Down<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Most teams doing container security scanning are not doing container vulnerability management. Scanning is a function. Management is a program. The difference shows up in production.<\/p>\n

NIST Special Publication 800-190, the Application Container Security Guide, organized container risk across five distinct layers: image, registry, orchestrator, container runtime, and host operating system.<\/strong><\/em>[2]<\/a> What most tooling implementations address is one or two of those layers, typically image scanning and some form of registry integration. The other layers receive partial coverage at best, and almost none of it is connected in a way that allows a finding in one layer to inform the response at another.<\/p>\n

The orchestration layer is a clear example. Kubernetes RBAC misconfigurations can let a process running inside a container access cluster-wide resources it was never supposed to touch. That exposure does not show up in an image scan. It exists entirely at the orchestrator layer, and a team relying on image scanning as its primary security control will not see it. Similarly, a container spawned from a clean, scanned image can still be configured to run in privileged mode, with a writable root filesystem, or with capabilities like CAP_SYS_ADMIN that effectively eliminate the isolation the container was supposed to provide.<\/p>\n

There is also the volume problem. The NVD enriched nearly 42,000 CVEs in 2025 alone, which was 45% more than any prior year, and the backlog continues to grow.[1]<\/a> Container scanners pulling from vulnerability databases without any prioritization logic produce finding lists that bear no resemblance to actual risk. A CVE scored 9.8 in an unused library package that has no public exploit path is not the same threat as a CVE scored 7.2 in an actively called dependency where exploit code is publicly available and already appears in CISA\u2019s Known Exploited Vulnerabilities catalog.[3]<\/a> When scanning tools treat these as equivalent, security teams face triage work that scales faster than their capacity to handle it.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Core Capabilities Worth Evaluating in Detail<\/h2>\n<\/div>\n<\/div>\n
\n
\n

The five-layer risk model provides a useful organizing structure here: image, registry, orchestrator, container runtime, and host operating system.[2]<\/a> Each layer carries distinct security risks, and each requires specific controls. What follows covers the capabilities that matter most at each layer, what separates substantive coverage from surface-level implementation, and what questions to ask during vendor evaluation.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Full-Stack Image Scanning, Not Just Package Matching<\/h3>\n<\/div>\n<\/div>\n
\n
\n

The minimum expectation for container image scanning is matching installed packages against CVE feeds. That baseline is necessary and, by itself, not sufficient. A capable container scanner must also parse Dockerfile instructions to catch misconfigurations before build, analyze file permissions embedded in image layers, detect hardcoded credentials and API keys that were written into the image during the development process, and assess container configurations against established security benchmarks like the CIS Docker Benchmark.[2]<\/a><\/p>\n

Base image selection matters more than most teams account for. General-purpose operating systems like Ubuntu or Debian carry package inventories built for broad use cases. A containerized application typically needs a fraction of those packages, but all of them are present, all of them are scannable, and any of them can carry security vulnerabilities. The same guidance specifically recommends using container-specific host operating systems with minimalist, read-only configurations to reduce the attack surface at the host level.[2]<\/a> The same logic applies one layer down: leaner base images mean smaller inventory, fewer vulnerabilities to track, and a narrower surface for attackers to work with.<\/p>\n

Scanning container images at image push is the trigger point most teams configure. That is reasonable as a starting condition. The evaluation question is what happens to images that have already been pushed and are already running. A scan gate at image push only catches problems present at that moment. Vulnerabilities disclosed the following week against packages already in production containers require a different capability entirely.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Registry Integration with Enforced Policy Gates<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Registry integration has two distinct meanings, and conflating them is a common evaluation mistake. The first meaning is that the scanner connects to private repositories to pull images for analysis. The second meaning is that the scanner can enforce blocking policy at the point of image promotion, preventing images that fail policy from moving forward through the pipeline at all. Both capabilities are useful. Only the second one provides control rather than visibility.<\/p>\n

When assessing registry integration, the questions that matter are: can policy thresholds be set per registry and per environment, so that a different severity tolerance applies to development versus production? Can image signing be enforced as a promotion condition, and does the platform support current signing approaches referenced in container security<\/a> frameworks? Can the platform track image provenance end-to-end, from the source commit that triggered the build through the registry where the image is stored to the running container instance consuming it?<\/p>\n

Fragmented enforcement across registries, where each registry has its own configuration managed separately, is one of the primary ways that policy exists on paper but fails in practice. The scanning tools show findings. No one blocked the deployment. The container runs.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Vulnerability Assessment of Running Containers<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Assessing container images at build time and registry push does not extend coverage to the fleet of containers already running in production. This is not a gap most scanning tools acknowledge prominently. It is, however, where exposure lives.<\/p>\n

A container image that was scanned clean in October will accumulate newly discovered vulnerabilities by January without a single line of code changing. The packages inside the image remain static. What changes is the threat landscape around them. Effective container vulnerability management requires the ability to maintain a current software inventory, or SBOM, for running containers and cross-reference that inventory against vulnerability databases continuously. When a new CVE is disclosed, every running container that contains the affected package should surface in the findings immediately, not only at the next scheduled build cycle.<\/p>\n

This capability matters most in environments where containers run for extended periods: database containers, message brokers, internal API services, and legacy workloads that move slowly through change management processes. These are exactly the environments where a build-triggered scan cadence produces the longest gaps in coverage.<\/p>\n<\/div>\n<\/div>\n

Runtime Threat Detection with Behavioral Context<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Runtime detection is categorically different from runtime configuration assessment. Configuration assessment checks whether a container is running privileged, whether the filesystem is writable, whether capabilities have been granted that should not have been. That is valuable, but it is static analysis applied at a point in time.<\/p>\n

Runtime threat detection monitors what is actually happening inside a running container, over time, as it processes work. That means tracking system calls, watching for process spawning behavior outside established baselines, flagging unexpected outbound network connections, and identifying file access patterns that suggest malicious code execution or credential access attempts. Federal container security guidance identifies intrusion detection at the host level as a required countermeasure, specifically noting that tools must be able to detect anomalous activity within containerized workloads.[2]<\/a><\/p>\n

The practical evaluation criteria here are specific. Does the tool establish per-container behavioral baselines or apply a generic detection model across all containers regardless of their function? A web server container and a batch processing container have entirely different expected system call profiles. A rule calibrated for one will generate false positives or miss real threats when applied to the other. Can the platform detect privilege escalation attempts (for example, a process inside the container calling ptrace, attempting namespace escapes, or modifying \/etc\/passwd)? And when a runtime event fires, does the alert carry enough context to identify the specific container, image, running process, and connection to any known vulnerability that may have enabled the behavior?<\/p>\n

Intrusion detection capability that generates an alert without those details creates investigation work rather than closing the loop on a threat.<\/p>\n<\/div>\n<\/div>\n

\n
\n

CI\/CD Pipeline Integration with Security as a Gate<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Security integration with CI\/CD pipelines<\/a> is claimed by virtually every container scanning tool available. The practical question is whether that integration functions as a reporting channel or as an enforced gate. Many implementations do the former: they run a scan, write findings to a dashboard, and let the build proceed regardless of what was found. That is telemetry, not control.<\/p>\n

A functioning security gate in a CI\/CD pipeline fails the build when findings exceed a defined severity threshold, returns specific remediation guidance to the developer within the pipeline output rather than routing it to a separate console, supports different policy thresholds per environment so that a critical finding in a development image triggers a warning while the same finding in a production image triggers a hard block, and requires no manual configuration for each new repository or service. The last point is not a minor operational convenience. In organizations running dozens or hundreds of microservices through independent pipelines, any integration that requires per-repository setup will not be applied consistently. Security controls that are applied inconsistently are, functionally, optional.<\/p>\n

The same framework specifically calls out CI\/CD pipeline toolchains as a required security boundary, noting that development pipeline components must be protected with the same rigor as production environments.[2]<\/a> That guidance treats the pipeline as part of the container attack surface, not a separate concern.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Host Operating System and Daemon Security<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Containers share the kernel of the host operating system they run on. That shared kernel is the reason container isolation is not equivalent to virtual machine isolation, and it is also why host-level vulnerabilities can undermine container security regardless of how well the container image itself was hardened. The guidance is explicit on this point, recommending host-specific operating systems over general-purpose ones and requiring that host-level security controls remain active alongside container controls.[2]<\/a><\/p>\n

From an evaluation standpoint, this means asking whether a candidate platform covers the Docker daemon configuration, host OS vulnerability state, and Docker host file integrity monitoring, not just the containers running on that host. A platform that only addresses the container layer while leaving the host unmonitored has a structural blind spot that attackers know to target. Lateral movement following a container compromise typically proceeds through the host, where a compromised container with excessive kernel capabilities can interact with other containers, access host filesystems, or reach network segments that the container should never have been able to touch.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Gaps That Common Tool Categories Leave Open<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Point solutions assembled across the container lifecycle rarely share enough context to catch what falls between their coverage areas. The table below maps the most common capability gaps to the evaluation criterion that directly addresses each one.<\/p>\n<\/div>\n<\/div>\n

\n
\n

\t\t\t\t\tCapability AreaTypical Gap in Point SolutionsEvaluation Criterion\t\t\t\t<\/p>\n

\t\t\t\t\tImage scanning coveragePackage matching only; misses Dockerfile misconfigs, secrets in layers, base image ancestryMulti-layer analysis including configuration and secrets detectionRegistry policyScan-and-report without promotion blockingEnforced policy gate at image push and promotion stagesRunning container assessmentNo continuous coverage after deploymentOngoing SBOM cross-reference against updated vulnerability databasesRuntime threat detectionSignature-based only; no behavioral baselining per containerPer-container baselines with system call monitoringHost OS coverageContainer-layer only; host left unmonitoredHost vulnerability, file integrity, and daemon security coverageOrchestration visibilityMisses RBAC misconfigs and Kubernetes-layer privilege escalationOrchestrator configuration assessment against CIS BenchmarksCI\/CD enforcementFindings reported to dashboard; build continuesHard-block policy gates with in-pipeline developer feedbackFalse positive managementFlat CVE lists without exploitability contextCVSS plus exploitability scoring with suppressible findings and audit trail\t\t\t\t<\/p><\/div>\n<\/div>\n

\n
\n

The false positive issue deserves direct treatment. When a scan against a single container image returns several hundred findings, with no indication of which are reachable, which have public exploit code, and which affect packages that are never called at runtime, the volume itself becomes the problem. That catalog exists precisely because CVSS score alone is a poor predictor of exploitation likelihood.[3]<\/a> A container vulnerability management program that does not incorporate KEV data into its prioritization is asking analysts to sort through noise to find what CISA has already flagged as confirmed active threats.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Build-Time and Runtime: How They Complement Each Other<\/h2>\n<\/div>\n<\/div>\n
\n
\n

The shift-left framing has produced a tendency to treat build-time scanning and runtime protection as alternative strategies rather than complementary ones. They address different threat classes.<\/p>\n

Build-time scanning catches what is known before a workload reaches production: vulnerable packages in the image, hardcoded credentials, misconfigurations in container configurations, and deviations from security policies that can be checked statically. It is the earlier and cheaper intervention point. Published federal guidance categorizes image risks as the primary container security concern precisely because they are addressable before deployment.[2]<\/a><\/p>\n

Runtime protection<\/a> catches what build-time analysis cannot. Zero-day vulnerabilities exploited against packages that showed no known vulnerability at scan time. Credentials injected at runtime through environment variables that were not present in the image. Lateral movement that originates from a compromised container and proceeds through the network to adjacent containers or host resources. Privilege escalation attempts that succeed because a Kubernetes service account was over-permissioned, not because the image was misconfigured.<\/p>\n

The gap between these two categories is where security teams get caught. A container can enter production clean and become a threat vector within days of a new CVE publication. Catching that transition requires runtime protection with continuous vulnerability cross-referencing, not another build-time scan.<\/p>\n

The evaluation criterion is connectivity between the two phases. When a runtime event fires, can the analyst trace it back to the specific image layer, the CVE that enabled the attack vector, and the registry entry where the vulnerable image was stored? Without that trace, a runtime alert is an investigation starting point, not a closed case.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Cloud and Orchestration Integration Specifics<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Container environments operate inside a broader context:<\/strong> Kubernetes or other orchestration solutions managing scheduling and networking, cloud provider IAM systems controlling what those containers can access externally, and registries that may span multiple cloud accounts and regions. A container vulnerability management solution evaluated in isolation from that context will miss security issues that exist specifically at the integration points.<\/p>\n

The catalog, which NIST now uses as its primary enrichment priority for the NVD, consistently includes vulnerabilities that are exploited through misconfigured access controls and API exposure rather than through vulnerable application code alone.[3]<\/a> Kubernetes API server exposure, over-permissioned service accounts, and unscoped IAM roles attached to container workloads are documented attack paths. They require orchestrator-level assessment, not just image scanning.<\/p>\n

Specifically, teams should assess whether a candidate platform covers these areas: Kubernetes RBAC configuration review, detecting service accounts with cluster-admin privileges or wildcard resource access; IaaS account monitoring across AWS, Azure, and GCP, including assessment of IAM policies attached to container and registry services; network segmentation analysis identifying containers with overly permissive ingress or egress that could enable lateral movement after initial compromise; and integration with SIEM platforms for alert correlation across container events and broader infrastructure telemetry.<\/p>\n

Multi-cloud container environments, where workloads run across two or three cloud providers simultaneously, amplify every one of these risks. Registry policies configured for AWS ECR<\/a> do not automatically apply to Azure ACR. IAM roles assessed in GCP do not cover the equivalent permissions in AWS. Any evaluation of a container security platform needs to account for whether it covers the full cloud footprint or only a subset of it.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Reducing Alert Volume Without Sacrificing Coverage<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Alert fatigue is a documented security operations problem, and container scanning tools are a frequent source of it. The issue is not that scanners find too many things. The issue is that most of what they find is not actionable in a meaningful near-term timeframe, and the volume of low-priority findings degrades the signal-to-noise ratio for the findings that are actionable.<\/p>\n<\/div>\n<\/div>\n

Without the expiration and audit trail, suppression becomes a way to ignore problems permanently, which undermines compliance defensibility.<\/span><\/p>\n

How Fidelis Container Secure Addresses This Evaluation<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Fidelis Container Secure<\/a> is the container security service of the Fidelis CloudPassage Halo platform. It is designed to automate security and compliance across Docker, Kubernetes, and CI\/CD pipeline infrastructure, functioning either as a standalone service or in conjunction with Fidelis Halo<\/a>\u00ae\u2018s server and cloud security services.<\/p>\n

The platform addresses multiple layers of the container stack simultaneously. At the image and registry layer, registry connectors scan container images at rest and track images in motion as they move toward production, with plugins integrating directly into CI\/CD tools including Jenkins, Bamboo, TeamCity, and CircleCI to pass or fail builds automatically based on configured policy. At the runtime configuration layer, Fidelis Container Secure collects detailed configuration and status information for container instances, Kubernetes services, and container runtimes, evaluating that information against security policies and best-practice rules to detect deviations. It can detect privileged containers, writable containers, interactive containers, and containers instantiated from unauthorized or unknown images.<\/p>\n

At the host level, the platform automates server instrumentation for discovery, inventory, vulnerability management, system hardening, system integrity monitoring, drift detection, and runtime security event collection. For intrusion detection and threat detection<\/a> at the Docker host and Kubernetes node level, Fidelis Container Secure uses log monitoring, file integrity monitoring, and intrusion detection capabilities, and can quarantine suspected rogue containers within seconds of detection.<\/p>\n

The platform deploys via a 2 MB microagent for Linux and Windows hosts, with Kubernetes-native DaemonSet support to automate deployment across every Kubernetes node. Ongoing inventory and assessments of container hosts and guest instances take under 90 seconds, and new microagents can be registered in under 30 seconds. All policy rules are grounded in CIS Benchmarks, PCI, HIPAA, and SOC 2 standards, with automatic rule updates as new threats emerge and container security best practices evolve.<\/p>\n

For cloud posture coverage across IaaS and PaaS resources, Fidelis Cloud Secure<\/a> operates as an agentless companion service, providing automated discovery, inventory, and assessment across AWS, Azure, and GCP, with monitoring across IAM services, virtual machine images, networks, storage, container registry services, managed Kubernetes services, and more. Used together, Fidelis Container Secure and Cloud Secure cover the container workload layer and the cloud infrastructure layer from a single unified security platform.<\/p>\n

Remediation guidance is delivered in real-time through DevOps tools that teams already use, including Jira, Slack, and ServiceNow, and findings are consolidated through the Fidelis Halo\u00ae Portal with interactive dashboards, prioritized issue reporting, and a REST API for programmatic integration with SIEM platforms and broader security operations tooling.<\/p>\n<\/div>\n<\/div>\n

What the Evaluation Should Actually Produce<\/h2>\n<\/div>\n<\/div>\n
\n
\n

A container vulnerability management evaluation that ends with a feature comparison has not answered the right question. The right question is whether the program closes specific gaps in the current security posture and whether it does so in a way that the team can actually operate at scale.<\/p>\n

Building that answer requires starting with an honest accounting of where the current program breaks down. If scanned images are accumulating vulnerabilities between scan cycles with no detection, the gap is continuous running-container assessment. If build-time scanning is producing thousands of findings with no clear remediation priority, the gap is exploitability-based signal quality. If runtime alerts fire without enough context to act on them, the gap is behavioral detection<\/a> and event correlation. If pipeline integrations exist but builds are not actually being blocked on policy violations, the gap is enforcement versus visibility.<\/p>\n

CISA\u2019s Known Exploited Vulnerabilities catalog and NIST SP 800-190 both establish what a rigorous container security program looks like from an authoritative standpoint.[2]<\/a>[3]<\/a> The evaluation criterion for any platform is how specifically and completely it operationalizes those requirements, within the existing pipeline architecture, cloud footprint, and security team capacity. That operationalization, not the feature list, is what separates a container security program that reduces exposure from one that produces reports.<\/p>\n<\/div>\n<\/div>\n
