Story

It's all handled.

Core puts builders and developers at the centre. By continuously adding improvements, we make life a little smoother for web professionals every day.

In 2021 we asked ourselves: if we used today's knowledge and technical capabilities to design the ideal hosting platform for web professionals - what would we build? The answer is Core.

Think of Core as a fully equipped workshop: the foundation is in order - the workbenches are there, the power comes out of the walls, the ventilation works - and everything else you need to do your work well and efficiently has been thought of.

Security, baked in.

Malware scans. Every 24 hours. Reported immediately.

Scrapers, credential stuffers, AI crawlers. Held at the gate.

Strict firewall. Full control.

Database encryption. One click.

Internet standards scanned on every site. We're the first and only hoster doing this.

Why this matters With modern internet standards (such as IPv6, DNSSEC, and HSTS), your projects stay available and secure. As the only hoster, we scan all your projects for modern internet standards by default. This gives you insight into areas for improvement. Many of them you can fix directly in Core.

Who did what, when. In plain sight.

ISO 27001 certified. Audited annually. Proof on paper.

Everything about our security →

Fast, by default.

New project in 60 seconds. Perfect config for your CMS or framework.

Full control over PHP settings. Per project.

Redis in one click. Pre-tuned for your workload.

Create a database. Automatic optimisation. One toggle.

Why this matters Every write leaves little fragments behind in your database. Over time those fragments slow queries down. We clean them up automatically (defragmentation) for MariaDB and PostgreSQL, so you never have to run OPTIMIZE TABLE yourself. And we're one of the only hosters doing this.

InnoDB insights. See exactly what's happening under the hood.

Why this matters The InnoDB buffer pool is one of the most important knobs for database performance. It keeps frequently-used data and indexes in memory, so queries don't have to hit disk every time. Set too small, you feel it in your response times. We size it for your workload and keep watching.

Everything to build & deploy with.

New tenants set up automatically. Via the Core API.

Per-tenant insight into resource usage. Immediately available.

Every project, its own environment. No fuss.

Architecture

Core under the hood.

Layer 1

Data centre

Power, network, physical security

Your servers run in heavily-secured data centres on Dutch and German soil. All hardware is our own. This is where certainty starts: redundant power supply, emergency power, fire detection systems, a geographically distributed network, and 24/7 physical access control.

Ede Schiphol-Rijk Meerbusch Tier-3 redundancy ISO 27001
Layer 2

Physical server

Lightning-fast hardware for lightning-fast projects

Our physical hardware is specially put together for outstanding web-hosting performance: AMD CPUs, ECC memory, and NVMe storage.

AMD EPYC ECC RAM NVMe storage
Layer 3

Virtual server (node)

Your own isolated environment

Every server your projects run on is a virtual server on physical hardware. During maintenance we can move your virtual servers between physical hardware, keeping uptime as high as possible.

Linux KVM Per-customer isolation Live migration
Layer 4

Interface

Manage all your projects

Through the Core interface you manage all your projects on your own server(s). Within Core you start new projects in under 60 seconds, choose the configuration so it fits your team, set up SSH access, and much more.

Want to automate processes further? The API is there for you.

Core control panel REST API SDK CLI Webhooks
Layer 5

Efficiency tooling

What saves your team hours every week

Core's real power lies in all the conveniences for web professionals: manage all your projects in one place, keep performance and security in view at a glance, get AI-assisted hypotheses when something goes wrong, get important notifications in your Slack, and we could keep going for a while.

Day in, day out, we develop new features and capabilities to make your daily work a little smoother.

Support

Support from real people who know what they're doing.

At Cyberfusion you find a unique combination of expertise and a human touch. You speak directly with engineers who understand what you're talking about, and who can actually help. When it really matters, you can count on us 24/7.

Advantages

What Core gets you.

Builders and developers get back to what they're good at, and you attract clients with a higher profile.

01

Let developers do what customers pay for
Server tuning, security patches, configuring firewall rules, fixing an outage at 3 in the morning - it has to happen, but you have better things to do. We take all of that off your plate, so your developers can get back to what they're paid for: building features for customers - on a foundation you know for certain is solid.
02

Win bigger clients with strict security requirements
Big prospects ask for a laundry list of security measures and assurances: ISO 27001, modern internet standards, a clearly defined SLA, uptime guarantees, a monitored supply chain - and the list goes on. We help you win that kind of client: first and foremost with all the technical and organisational measures. Need our help on tenders and procurement? We're glad to chip in.
03

24/7 direct help from qualified engineers
Let's be honest: inherent to technology and building sites and applications is that sometimes something needs fixing. In that case, you can count on our qualified engineers not putting their laptop away until the problem is fixed. By the time you read that something was going on, nine times out of ten the fix and the post-mortem are already there. That brings a lot of (mental) peace to your organisation. You could almost call it priceless - but Core is simply perfectly affordable!
04

Partner for the next 10+ years
Like the rest of the industry these days: we regularly get suitors at the door with acquisition offers. We turn them down - including one from one of the largest hosters in Europe. Because money is nice, but you can't buy what matters (figuratively): we'd rather build a platform web professionals actually benefit from than drink endless cocktails. Let's be honest: nobody can promise they'll never be acquired - we at least don't have a crystal ball - but we've put customers before profit for ten years and plan to keep it that way.

Clear answers to good questions

Yours not here? Ask it - we're happy to think along.

Our data matters! What do backups actually look like with you?

At least one backup every 24 hours, on-site and off-site. Restoring a file, a database or a whole project is a click away. In Core, you can also make backups yourself - handy right before a risky update.

Where does my data live, anyway? Europe, right?

Of course! Every data centre is in Europe: currently the Netherlands and Germany, and your server runs on our own hardware. Your clients can impose the strictest privacy requirements and you'll pass them with flying colours. See the data centres or read why we choose Europe.

What happens during a migration, and will my visitors notice?

We adapt the approach per project. Bulk migrations often finish without downtime; webshops or applications with transactional data may need a brief pause so no order or change falls through the cracks. See how our Shift method works.

How fast can I scale up for a campaign or traffic peak?

A resource change is live within a couple of minutes. Schedule it for a quiet moment in advance, or call at 22:00 saying you need more resources now and they get added now. For sustained peak load, it's also possible to run multiple servers in a load-balanced cluster - we're happy to think it through with you.

Is custom work possible?

Yes. With Core you get a rare combination of standardisation and custom work: custom is possible (like a VPN tunnel, or your own CA certificates), but projects always start from a carefully thought-out standard.

What do you build with?
