Kubernetes · Cloud security · Platform engineering
We set up, audit, harden and run Kubernetes and cloud infrastructure.
acks.io is an infrastructure engineering company in Helsinki, Finland. Hire us to set up Kubernetes or migrate your services onto it, for a fixed-scope security or cost audit, to implement the fixes, or as a fractional platform team that runs your AWS, Google Cloud or Azure platform with you.

Services
What you can hire us for
Three ways to work with us, depending on whether you need an answer, a fix or a team.
Assess
Fixed-scope audits with a written report and a prioritised remediation plan.
- Kubernetes Security AuditRBAC, workloads, network policies, supply chain and cluster configuration, reviewed against public hardening benchmarks.Fixed scope
- Kubernetes Cost OptimizationRequests, limits, node pools and autoscaling — where your cluster spend goes and how to reduce it safely.Fixed scope + optional implementation
- Cloud Infrastructure AuditSecurity, architecture, reliability and cost review of your AWS, Google Cloud or Azure environment.Fixed scope
Fix
Projects that build and change things — Kubernetes setups and migrations, hardening, cloud platforms and delivery.
- Kubernetes Setup & MigrationProduction-ready clusters on EKS, GKE, AKS or on-prem, and migrating your services onto them from VMs, PaaS or an older cluster.Project
- Infrastructure HardeningWe implement the fixes: identity, network isolation, encryption, policy guardrails and secure defaults.Project
- Cloud Architecture & MigrationsCloud platform builds, landing zones, cloud and region migrations, and finishing migrations that stalled.Project
- CI/CD, IaC & GitOpsTerraform, delivery pipelines and GitOps workflows your team can own.Project
Operate
Ongoing ownership of your platform, as an extension of your engineering team.
- Fractional Platform EngineeringSenior platform engineers embedded in your team, owning the infrastructure roadmap part-time.Ongoing
- Managed Cloud & KubernetesWe run your cloud and Kubernetes day to day: upgrades, patching, monitoring, incidents and cost control.Ongoing
- 24/7 On-CallSenior engineers on your pager with defined response targets, runbooks and post-incident reviews.Ongoing add-on
Is this relevant to you?
Teams usually call us in one of these situations
- Kubernetes is in production, but nobody owns the platform.Product engineers patch clusters between features, and upgrades keep slipping.
Fractional Platform Engineering → - A security review or SOC 2 / ISO 27001 audit is coming.You need to know what an auditor or an attacker would find first.
Kubernetes Security Audit → - The cloud bill grows faster than your traffic.Nobody can say which workloads or teams are driving it.
Kubernetes Cost Optimization → - One engineer knows how everything works.If they are on holiday, production changes wait.
Managed Cloud & Kubernetes → - You inherited an environment you don't fully trust.After an acquisition, a team change or years of quick fixes.
Cloud Infrastructure Audit → - You want to move to Kubernetes, or a migration stalled.Services run on VMs or a PaaS, or half of them moved and the rest are waiting on a plan.

How an engagement works
Scoped in writing before anything starts
Scoping call
30 minutes with an engineer. We learn your environment, your constraints and what is worrying you.
Written scope and fee
You get the scope, deliverables, required access and a fixed fee in writing.
Review or build
Audits run with read-only access. Projects are delivered as code in your repositories.
Report and handover
A findings readout or a handover with documentation and runbooks. Then you decide what comes next.
Why acks.io
Why teams trust us with production
- Senior engineers only. The people on the scoping call are the people doing the work.
- Everything as code. Terraform and Git-managed configuration in your repositories, not ours.
- No lock-in. Documentation, runbooks and training are part of every engagement.
- Least privilege, including for us. Read-only access for audits; write access only when you ask us to change things.
| With acks.io | Typical agencies |
|---|---|
| Direct senior attention | Layered account structure |
| Embedded collaboration with your engineers | Transactional hand-offs |
| Fast iteration and short feedback loops | Slow, multi-phase cycles |
| Tailored, context-aware solutions | One-size frameworks |
| No lock-in: full docs, runbooks and training | Opaque tooling and retained dependency |

FAQ
Frequently asked questions
What is acks.io?
acks.io is an infrastructure engineering company based in Helsinki, Finland. We audit, harden and operate Kubernetes and cloud infrastructure for engineering teams — either as fixed-scope engagements with a clear end, or as an ongoing fractional platform engineering team.
Can acks.io set up Kubernetes or migrate us to Kubernetes?
Yes. We build production-ready Kubernetes clusters on EKS, GKE, AKS or on-prem, and migrate services onto them from virtual machines, Docker hosts, PaaS platforms or an older cluster, one service at a time with a rollback path.
Which clouds and platforms do you work with?
AWS, Google Cloud and Microsoft Azure, as well as Kubernetes running on-premises. We are not tied to a single provider, and we work with managed Kubernetes (EKS, GKE, AKS) and self-managed clusters.
What is the difference between an audit and fractional platform engineering?
An audit is a fixed-scope engagement: we review a defined part of your infrastructure and deliver a written report with prioritised findings. Fractional platform engineering is ongoing: our engineers work as part of your team and own platform work month to month.
Do you need write access to our infrastructure to run an audit?
No. Audits are run with read-only access that you grant and revoke. Write access is only needed if you later ask us to implement the fixes.
How do we get started?
Book a 30-minute call. We ask about your environment and what is worrying you, then propose a scope and a fixed fee in writing.
