Containers inherit every weakness baked into their images and build pipeline. Our container security assessment reviews your Docker images, registries and runtime configuration for vulnerable dependencies, leaked secrets and unsafe defaults that undermine isolation.
We trace risk from base image and build args through to running workloads, then prioritize the fixes that matter most.
Our container security assessment reviews your Docker images, registries and runtime configuration for the weaknesses that undermine isolation. We analyze image layers and dependencies, hunt for secrets embedded in layers and build arguments, check registry access controls, and review runtime privileges and capabilities. Aligned to the CIS Docker Benchmark and NIST SP 800-190, we trace risk from base image and build pipeline through to running workloads.
Containers inherit every weakness baked into their images and build pipeline, and vulnerable dependencies or leaked secrets propagate to every workload that runs them. Secrets committed in an early image layer survive even after being deleted.
A container security assessment traces risk from base image and build args through to running workloads, prioritizing the fixes that most reduce your real attack surface.

Our methodology
Scoping & rules of engagement. We agree objectives, targets and boundaries for your container security assessment, so testing is safe, authorized and focused on what matters to your business.
Reconnaissance & mapping. We enumerate the full attack surface in scope, building a complete picture before any exploitation begins.
Manual exploitation. Our senior testers chain vulnerabilities by hand — going far beyond automated scanners — to prove real, demonstrable impact.
Analysis & reporting. Every finding is triaged, risk-rated with CVSS and written up with a copy-paste reproduction and clear remediation.
Remediation support & free retest. We support your team through the fixes and retest the remediated issues to confirm they are genuinely closed.
Tools & techniques
We analyze images, registries and runtime configuration using container-scanning tools and manual review. We inspect image layers and dependencies, hunt for secrets in layers and build arguments, review registry access and runtime privileges, and assess Dockerfiles against the CIS Docker Benchmark and NIST SP 800-190, tracing risk from base image and build pipeline through to running workloads.

As part of securing a CI/CD and container supply chain
What you receive
Image and registry findings
Supply-chain risk assessment
Runtime hardening recommendations
Free retest of rebuilt images
What’s included in your report
Every container security assessment engagement concludes with a comprehensive, board-ready report and a working session to walk your team through it. Your report includes:
An executive summary with overall risk posture for non-technical stakeholders
Detailed technical findings, each with a step-by-step, copy-paste reproduction
CVSS v3.1 severity ratings and business-impact context for every issue
Prioritized, actionable remediation guidance your engineers can apply directly
A complimentary retest to confirm fixes and update finding status
A formal attestation letter for customers, auditors and compliance programs
After your container security assessment, you will have clear, evidence-based visibility into your real security risk — not a scanner’s guesswork. You will know exactly which weaknesses an attacker could exploit, what the business impact would be, and the precise steps to fix them in priority order. Teams use our findings to close critical gaps, satisfy customer and regulator security requirements, and demonstrate due diligence to their board. With a complimentary retest included, you also get documented proof that the issues are genuinely resolved.
Engagement details & logistics
Every container security assessment starts with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal and a clear statement of work. Most engagements are delivered fully remotely, with on-site work arranged where it genuinely adds value. Throughout testing we maintain an agreed communication cadence and escalate any critical, high-impact finding to you immediately rather than waiting for the final report. All work is performed under a signed NDA with strict data-handling controls, using safe, non-disruptive techniques and carefully coordinated rules of engagement to protect your production systems. On completion you receive your report and a walkthrough session, followed by a complimentary retest once your fixes are in place. Typical engagements are booked one to three weeks in advance, and urgent or pre-deadline testing can often be accommodated — just ask at hi@agentoffense.com.
Why organizations choose AgentOffense
Our container security assessment is delivered by senior offensive-security engineers who test the way real attackers do — manually, creatively and with a relentless focus on proving genuine, demonstrable impact. Here is what sets our engagements apart:
Manual, exploit-driven testing that chains vulnerabilities the way a real attacker would, going far beyond what automated scanners can find.
Reproducible proof for every finding, with copy-paste reproduction steps your engineers can follow and independently verify.
Honest severity calibration so you invest in fixing what genuinely matters and avoid wasting effort on false positives and noise.
Clear, business-focused reporting that speaks to engineers and executives alike, tying every issue to real-world impact.
A complimentary retest included, so you get documented proof that your fixes actually close the attack path.
Responsible, collaborative delivery with a named point of contact and secure handling of all data throughout the engagement.

How much does Container Security Assessment cost?
Every container security assessment is scoped and priced individually, so you pay for exactly the coverage you need — with no hidden extras. After a short, no-obligation scoping call we send a fixed-price quote, usually within one business day, with clear deliverables, a firm timeline and a complimentary retest included. The price of your container security assessment depends on the size and complexity of the target and the depth of testing required, so you always know the cost up front before any work begins.
No — it focuses on the containers and images themselves. It pairs naturally with Kubernetes penetration testing, which targets the orchestration layer.
Do you check for leaked secrets in image history?
Yes. Secrets committed in earlier layers survive even if deleted later, and we specifically hunt for them.
Can you integrate checks into our CI/CD?
We can recommend and help wire in image and supply-chain checks so issues are caught before deployment.
Is this the same as Kubernetes testing?
No — it focuses on the containers and images themselves, and pairs naturally with Kubernetes penetration testing, which targets the orchestration layer.
Can you integrate checks into our CI/CD?
Yes. We recommend and help wire in image and supply-chain checks so issues are caught before deployment.
Do you check for secrets in old image layers?
Yes. Secrets committed in earlier layers survive even after deletion, and we specifically hunt for them across image history.
Can you help integrate checks into CI/CD?
Yes. We recommend and help wire in image and supply-chain checks so issues are caught before deployment.
How long does a container security assessment take?
Typically one to two weeks depending on the number of images and pipelines in scope.
Can you help harden our build pipeline?
Yes. We provide runtime and supply-chain hardening guidance and can help integrate image checks into CI/CD.
