Sandbox Escape Prevention for Security Engineers · harden the layers, choose the boundary, monitor behavior, contain the breach
Contain untrusted code as deliberate, layered defense in depth, not a single default container you hope isolates.
Every control handed to you adopt-ready, from the containment architecture standard and the threat-model-based boundary decision through dropped capabilities, rootless execution, seccomp-bpf and mandatory access control, mount hygiene, network segmentation and default-deny egress, to runtime detection and a rehearsed air-gapped incident response.
Ready in a weekend, not a quarter.

Here is the honest situation. Here is the honest situation. You increasingly have to run code you do not trust, customer scripts, third party plugins, hostile file parsers, AI-generated programs, and the everyday sandbox is a container, which is a process on the host's shared kernel, not a box. The kernel is the boundary an attacker inside pushes on, and a container escape is what happens when they push through it to the host. You cannot make that risk vanish by trusting a default runtime, and you cannot wave it through without eventually explaining a host or cluster compromise. Containing it is an engineering discipline, harden the shared-kernel layers, drive misconfigurations to zero, choose the boundary strength honestly, watch runtime behavior, and bound the blast radius so a breach is confined.

This Kit removes the guesswork. It is untrusted-code containment written as adopt-ready controls, so a sandbox is hardened, its boundary is matched to the threat, its misconfigurations are closed, and its breach is contained, on the record, rather than assumed safe because the container started.

What you get, the moment you buy

18
Controls, adopt-ready. Every control, written so you personalize and apply it.
18
Evidence-they-examine checklists. For each control, exactly what a reviewer examines, plus where teams fall short, so you close the gap first.
1
Control Matrix, pre-built. Every control in a working spreadsheet, ready to record status, owner and evidence location.
1
Gap & Readiness Assessment. Score each control and the workbook returns your readiness as a single percentage, and exactly what to fix next.

Grounded in real Linux container and kernel isolation practice, including namespaces and cgroups, Linux capabilities and capability dropping, rootless and user namespaces, seccomp-bpf syscall filtering, AppArmor and SELinux mandatory access control, the container escape classes, gVisor, Kata Containers and Firecracker microVMs, network segmentation and egress control, Falco, eBPF and auditd runtime monitoring, and air-gapped, blast-radius-limited incident response.

Contain the code, do not just run it
Untrusted code gets placed in a default container and assumed isolated, and the fix is layered containment suited to how containers actually work, a shared kernel with restrictions, not blind trust. This Kit builds the containment architecture standard, the boundary decision, the capability, rootless, seccomp and mandatory access control layers, the mount hygiene that closes the common escapes, the network segmentation and egress control, and the runtime detection and air-gapped incident response that keep a breach contained.

What one control looks like

This is the opening control, where the containment architecture begins. All 18 are built to this depth.

SBX-1 Maintain a containment architecture standard for untrusted-code workloads CONTAINMENT ARCHITECTURE AND BOUNDARY DECISION
Put this control in place

Require [your organization name] to maintain a documented containment architecture standard for every untrusted-code workload that specifies the required independent layers, namespace and cgroup isolation, capability dropping, seccomp-bpf filtering, mandatory access control, network segmentation and the isolation boundary, and names, for each layer, the escape class it answers and the residual risk it leaves.

Control note.

Treat the standard as the review checklist every new sandbox must pass, not a document written once and filed.

Evidence a reviewer examines
  • The written containment architecture standard listing the required layers
  • A per-workload mapping of each layer to the escape class it counters
  • A record that new untrusted-code workloads are reviewed against the standard before launch
Common finding they raise: Untrusted code is placed in a default container and assumed isolated, with no layered design and no statement of what each control actually counters.

Why this is not another template pack

  • The boundary is the point. A shared kernel is the surface an escape attacks, so the design has to name what each layer counters and decide honestly when hardened containers are enough and when the code needs a gVisor, Kata or Firecracker boundary. This tells you how, for every control.
  • The escape classes built in. Kernel vulnerabilities, over-broad mounts, an exposed runtime socket, privileged containers, exposed /proc and /sys, capability dropping, rootless, seccomp and mandatory access control, segmentation and egress, runtime detection and air-gapped response are written into the controls, not left generic.
  • Built on real mechanisms, not one runtime. The controls are principle-level, so they hold across container runtimes, orchestrators and boundary technologies, and stay useful as isolation tooling evolves.

Who buys this

Security architects and DevSecOps engineers responsible for isolating high-risk and untrusted workloads.

By the end of the weekend you will have
✓  An adopt-ready control for all 18 areas
✓  A completed control matrix
✓  The evidence a security reviewer and an auditor examine
✓  A containment architecture standard and a threat-model-based boundary decision
✓  Hardened capability, rootless, seccomp and mandatory access control layers, mount hygiene, and default-deny egress with segmentation
✓  A readiness percentage and a fix list

Common questions

Is it really editable? Yes. Word and Excel files you own and adapt. No portal, no subscription.

Does it cover the whole containment method? Yes. The containment architecture and boundary decision, kernel privilege reduction with capabilities and rootless, syscall and mandatory access control confinement, mount hygiene and misconfiguration prevention, network segmentation and egress control, and runtime detection and air-gapped incident response each have their own controls with their own evidence.

Is this tied to one container runtime or boundary technology? No. The controls are principle-level, dropped capabilities, rootless, seccomp-bpf, mandatory access control, mount hygiene, segmentation, and a boundary decision, so they apply across container runtimes and across gVisor, Kata Containers and Firecracker.

Who is it for? Security architects and DevSecOps engineers who must isolate untrusted, high-risk workloads and defend the containment to a security review and an auditor.

Do not let your next security review find untrusted code in a default container, a mounted runtime socket, a privileged sandbox, or a breach with no bounded blast radius.
Every control is fast to adopt with the Kit. It is instant, and it is guaranteed.
Add it to your cart and be ready this weekend.
