Resource hub for hosting and DevOps teams

Practical guides, documentation and service pages for engineers who run servers at 4hosting. Start from the task in front of you: secure a server, move from another provider or put your included hours to work.

Everything here is written for people who operate servers, not only for people who buy them. The security guide and the documentation work from commands and configuration, the service pages explain what the DevOps, programming and CyberSecurity hours cover, and the pricing page lists what each plan includes.

Most teams arrive in one of three situations: a production server that needs hardening, a website or mail platform that has to leave another provider, or a backlog of infrastructure tasks nobody has time for. The shortcuts below map to those cases.

Server security guide

Questions and answers on hardening a production server, with commands, examples and the mistakes teams keep repeating.

DevOps, programming and CyberSecurity

What each service covers, which technologies we work with and how included hours are requested.

Mailu and SMTP relay guide

Self-hosted mailboxes, a separate transactional relay and the DNS records that keep mail out of spam.

Documentation

Getting started, migration, backups, containers and infrastructure, gathered in one place.

Hosting solutions

What each plan family includes and which workloads it fits: cPanel, VPS, dedicated and GPU servers.

Contact and support

Write to the team in English or Romanian, or open a request from the client panel.

Start from the task

Six common jobs, each with the page that answers it.

Hardening a production server

Work through the security guide: SSH, firewall, 3-2-1 backups, HTTPS with HSTS, WAF, containers and the npm supply chain, with commands you can run.

Open the security guide

Moving from another provider

Migration is free and planned together: an inventory, the copy, a test on a temporary domain and the DNS switch last.

Setting up business e-mail

Mailu mailboxes on your own domain, a separate SMTP relay for application mail and the SPF, DKIM and DMARC records that decide whether messages reach the inbox.

Open the Mailu guide

Running containers in production

Minimal images built in CI, non-root users, isolated networks, secrets kept outside the image and rollouts you can reverse.

See the container guide

Putting included hours to work

Plans from cPanel Advanced upward include monthly DevOps, CyberSecurity and programming hours. See what they cover, then request them from the client panel.
