RHYTHMIC SECURE BUILD
AI-Driven Supply Chain Attacks.
We Build the Layers That Stop Them.
Rhythmic hardens the way your team builds software, from the dependencies you pull to the credentials sitting on developer laptops. A compromised package, or a hijacked AI coding agent, runs into layers built to stop it long before it reaches production or your customers’ data.

The Breach Rarely Starts with Your Code
It starts with what your code pulls in, and where your credentials sit while it runs. AI made that attack cheaper and faster, and the coding agent on a developer’s machine is a new way in. We have seen these patterns enough times to spot them on a discovery call.
Untrusted code, one step from production
Developers run
npm install, docker pull, and AI coding assistants on machines that can reach production and customer environments. The credentials are right there in files on those laptops. A compromised dependency does not have to work hard to find them. One identity boundary doing all the work
Often a single identity stands between checking email and deploying to a customer’s cloud. GitHub Actions stay pinned to mutable tags that an attacker can quietly repoint. One thin wall is doing a lot of load-bearing work.
A scanner or two, mistaken for a strategy
Most teams add a scanner and consider the problem handled. A scanner is one layer. Defense in depth is several independent layers, where one failure still leaves the attacker with very little. The gap between one layer and several is room for an attacker to work.
No detection, no record it happened
A supply-chain payload runs, takes what it wants, and erases itself in seconds. With no detection layer, there is nothing left to tell you it happened. Most teams find out from someone else.
What You Get with Rhythmic Secure Build
The same engineering rigor we apply to cloud and security, applied to how you build software. Deployed and working, not just diagrams.
Pipeline Assessment & Architecture
We assess your current pipeline and posture against an eight-layer model, threat-model your stack, and design an architecture tuned to your risk tolerance and existing tools. You get a clear picture and a real plan before any build begins.
Hardened CI/CD Pipeline
Self-hosted runners and CI gates, with CI actions pinned to immutable commits instead of mutable tags. We convert representative pipelines so you can watch the pattern work in your own stack.
Zero-Disk Credentials
A secrets audit across laptops, CI/CD, and running code, with credentials moved out of files. 1Password Environments on laptops, Service Accounts for CI/CD, and appropriately-scoped OIDC roles.
Dependency Defense & Artifact Control
Scanning and gating on what enters your build with Socket.dev or an equivalent, plus a configured artifact repository that proxies what you pull. Open-source Nexus usually does the job.
Zero Trust Access & Device Posture
Cloudflare Zero Trust protecting your artifact repo, internal services, and developer laptops, with production access gated on the real-time state of the machine asking for it.
Detection & Forensic Trail
Endpoint detection on developer machines and SIEM rules that give you a trail when something gets through. This is the layer that tells you someone tried.
How the Engagement Works
Three phases. You commit to a low-risk diagnostic first, we test and prove the model, then decide on the build with a real plan and a real number in hand.
PHASE 1
ASSESS & ARCHITECT
We get in, assess your pipeline against the eight-layer model, threat-model your stack, and produce a high-level architecture tuned to your risk tolerance and existing tooling. Flat fee, low risk.
PHASE 2
PROTOTYPE
We implement the architecture on one project first, proving the model in your environment before any broader rollout.
PHASE 3
IMPLEMENT & HAND OFF
We write the detailed implementation plan, deploy the layers as a working rollout, and hand off design docs, implementation docs, a runbook, developer guides, and live SIEM rules if they are in scope.
WHY RHYTHMIC
We Built This for Ourselves First
The eight-layer architecture runs in Rhythmic’s own production environment every day, designed and hardened after the March 2026 Trivy and Axios compromises made the threat concrete. Behind it is a team at a rare intersection of IT, cybersecurity, and AI, with decades of award-winning security leadership and experience securing emerging technology.
This Service is Right For Companies That...
✓ Ship software and let developers run untrusted code with a path to production.
✓ Have up to 100 engineers operating on cloud-native infrastructure with federated identity.
✓ Handle sensitive customer data or operate inside your customers’ environments.
✓ Know the threat is real and want to act without grinding development to a halt.
✓ Got rattled by a real incident, a customer security review, or a near-miss.
✓ Run multi-tenant patterns with separate corporate and production identity.
