Security built into the pipeline, not bolted on after the breach.

13 articlesEN · DE

Security is not a feature you add at the end — it is a property of how you design, build and ship software. The teams that stay out of incident channels bake it into the workflow: threat modeling before code, pipelines that fail closed, and auth that is boring because it is correct. I treat security as an engineering discipline with measurable controls, including in regulated enterprise systems, backed by CSA CCSK and CCZT.

    Wazuh vs Microsoft Sentinel vs Google SecOps: The SIEM You Pick Is the Bill You Get

    Three SIEMs, three completely different meters: Sentinel bills the gigabytes you ingest, Google SecOps bills packages with detection-rule limits and will not publish a price, Wazuh bills agents or nothing at all. The model you choose quietly decides what your team is willing to log — and therefore what you can investigate.

    Is Keycloak Free? Keycloak vs authentik and What Each Really Costs

    Keycloak is Apache 2.0 with no paid tier. authentik is open core — MIT plus a proprietary enterprise directory. That licensing difference matters more than any feature table, and SCIM coverage is not equal either.

    OPA vs Kyverno in 2026: Kubernetes Ships Policy Now

    Kubernetes now enforces policy in-process: ValidatingAdmissionPolicy went stable in 1.30, MutatingAdmissionPolicy in 1.36. So the real question is no longer OPA or Kyverno — it's what you still need a controller for.

    Tokenization vs Encryption: What Actually Takes Data Out of Scope

    "We encrypted everything" does not take a system out of PCI DSS scope, and tokenization does not take you out of GDPR. A practical guide to what each one actually buys you — and where teams get it wrong.

    User-Level Permission Controls for MCP Tool Access with an Enterprise MCP Gateway

    MCP gives your AI agents real power — reading files, calling APIs, moving money. But who decides which user or agent can reach which tool? Here is how an enterprise MCP gateway turns that question into a policy you can actually enforce, from the gateway down to every laptop.

FAQ

What is your security background?
I build and harden production systems at scale, including regulated enterprise systems — DevSecOps pipelines, AppSec, auth and supply-chain hardening — as a Google Cloud Ambassador with CSA CCSK and CCZT.
Are you available to hire?
Yes — threat modeling, AppSec reviews, DevSecOps pipelines and auth design, as a contract, consulting or selected full-time engagement, remote across the EU or on-site in Germany. I work fluently in English.
How do we start working together?
Tell me what you need to secure — a product, a pipeline, an auth layer — on the contact page, and I will reply with how I can help.

Want security that ships with you?

From auth design to hardened CI/CD and supply-chain defense, I help teams build security into the workflow instead of patching it after an incident.
