"No nonsense, just practical solutions. The pricing was transparent, and the service model made sense. That down-to-earth attitude is exactly what we were looking for."
Your platform, fully managed
Your team didn’t get into development to manage patches, plan migrations, or manage infrastructure. We take all of that off your plate: getting you to Cyso without the chaos, then keeping your environment monitored, secured, and maintained so you can stay focused on building.
At Cyso, we’ve been doing this for close to 30 years: migrate, run and secure production platforms for the teams who build on them.

Three services, one platform
Every platform goes through the same three phases: getting there, keeping it running, and keeping it secure. Wherever you are on that line, one of these picks it up. Most of our customers use all three.
Migration & Deployment
Our engineers review your architecture, map your workloads, run the cutover alongside your team, and stick around in the weeks after to make sure it holds.
- ✔ A migration plan built on your real environment
- ✔ Engineers who stay through go-live and after
- ✔ CI/CD and automation set up the way you work
Managed Cloud Operations
Since 1997, our team has handled patching, updates, capacity and disaster recovery for the platforms we run. Your developers keep building. We keep the infrastructure from becoming their problem.
- ✔ 24/7 monitoring from our NOC
✔ Updates in agreed maintenance windows
✔ Backups and recovery procedures we actually test
Cybersecurity Solutions
Threats don't pause for the weekend, and neither do we. We take a layered approach to securing your platform: finding vulnerabilities before they're exploited and keeping your environment hardened against what's next.
✔ 24/7 threat monitoring from our SOC
✔ Proactive patching and vulnerability management
✔ DDoS, intrusion and firewall protection
Managed by a Dutch team, audited to the highest standards
You’re working with our own engineers, in our own certified data centres, under Dutch and European law. Cyso holds ISO 27001 and NEN 7510 certifications, all data stays in Europe, and management is performed by our own employees. Nothing is subcontracted.
Cyso Cloud runs on our own network and data centre infrastructure, built and maintained by our engineers. That means direct connectivity, low latency, and room for multi-cloud and multi-data-centre architectures without third-party dependency.

What you can expect from all three solutions
Whichever service you start with, the way we work stays the same. These are the constants.
Watched around the clock
Our Mission Control team monitors your applications and the platform itself, from independent environments. When something looks wrong, we investigate and intervene. We don't wait for your team to notice.
Direct contact with real engineers
Clear escalation paths, and someone who knows your environment on the other end of the line. Recovery objectives are agreed up front and contractually backed.
Reporting you can hand to an auditor
Platform health, incidents and capacity trends in one place, monthly. Evidence is kept as we go, so audit questions are answered from record, not memory.
Trusted by companies all over Europe
From migration to daily operations, here’s what working with us looks like in practice.
Not sure where to start?
That’s what the discovery call is for. In about 30 minutes we look at your setup, tell you which of the three services fits where you are, and give you a straight answer on what it would involve.
