Core Capabilities

Our Core Competencies

We design and engineer robust, scalable, and future-proof systems tailored to complex enterprise processes.

DevOps, Infrastructure as Code & GitOps

We design and operate production-grade environments and declare your infrastructure using Terraform/OpenTofu and Ansible. We optimize your cloud systems sustainably through automated release workflows and continuous FinOps cost analysis.

Automation & Cloud-Native Tooling

We develop custom DevOps workflows, Kubernetes deployments, and API integrations in Python and Go to automate complex operational workflows, eliminate manual errors, and integrate systems seamlessly.

Strategic IT Consulting & Migration Support

We accompany you from the initial migration concept to final system acceptance. Through vendor-neutral audits, cloud-migration roadmaps (on-premises to cloud), and tech-stack reviews, we minimize project risk.

Observability, Monitoring & Proactive Alerting

We establish comprehensive monitoring environments based on Prometheus, Grafana, and Loki. The toolset is enhanced by our proprietary monitoring platform WatchGrid to proactively secure your system uptime.

Methodology

Our Process

Four structured phases to build a stable, future-proof, and compliance-compliant IT platform.

01

Audit & Analysis

We analyze your existing system landscape, identify performance bottlenecks, and evaluate your security and cost structures.

02

Concept & Blueprint

We design a future-proof, vendor-neutral target architecture and define a pragmatic, low-risk migration roadmap.

03

Implementation

We build your infrastructure as code (IaC). Through automated CI/CD pipelines, we establish reproducible and secure deployments.

04

Enablement & Handover

We document all systems comprehensively and train your internal teams, ensuring you maintain complete sovereignty over your platform.

Quality Promise

Why STHEOS

We combine deep technical expertise with agile delivery and a commitment to data sovereignty and infrastructure independence.

True Data Sovereignty & Compliance

100% GDPR-compliant implementation, complete data sovereignty, and a deep understanding of regulatory compliance in European B2B markets.

Mitigation of Vendor Lock-in

We prioritize open-source standards (Kubernetes, Terraform, Go) to keep your business independent of specific cloud vendor monopolies and licensing changes.

Senior Engineering & Direct Access

Work directly with seasoned IT architects. No administrative overhead or junior consultants – just pure engineering expertise on equal footing.

Security & Stability via Validation

Infrastructure modifications are automatically analyzed for security risks, misconfigurations, and compliance rules prior to deployment using automated checks (IaC scanning & Policy-as-Code).

Data Sovereignty & Compliance for Europe

As a German IT firm, data privacy, compliance, and secure architectures are hardwired into our engineering culture.

🇪🇺

European-First Hosting & GDPR Compliance

We deploy and host your systems preferably in European data centers (e.g., Hetzner, OVHcloud, or European zones of AWS/Azure). This guarantees absolute compliance, minimized latency, and protection against unauthorized data access from non-EU jurisdictions (Cloud Act).
