Arsys Review 2026: Spain's Leading Host Tested

Arsys has been the dominant web host in Spain for nearly 30 years. Most people outside Spain have never heard of it. That gap tells you something useful: this isn’t a host that grew by chasing the global affiliate circuit. It grew by being the default choice for Spanish businesses, agencies, and public sector organisations that needed local infrastructure and Spanish-language support.

Whether that track record is enough to make it the right host for you depends heavily on what you’re building and where your audience is. This review covers shared hosting, VPS, dedicated servers, reseller plans, business email, and Microsoft 365 so you can make that call with full information, including the renewal pricing that Arsys does not exactly shout about.

About Arsys

Arsys was founded in 1996 in Logroño, a city in La Rioja in northern Spain. It became the leading web host in the Spanish market and has held that position ever since, serving more than 250,000 customers and managing over 1.2 million active services.

Since 2013, Arsys has been part of the IONOS Group, the European hosting and cloud division of United Internet AG. That matters because it gives Arsys access to IONOS Group’s wider infrastructure in Germany, the UK, France, and the USA, while keeping its own Tier III certified data centre in Logroño as the primary facility for Spanish hosting customers.

That Logroño data centre opened in 2009 and expanded in 2019. It now covers 6,000 square metres, with 1,000 square metres of technical floor space across four independent rooms and capacity for over 20,000 physical servers. It holds Tier III certification from the Uptime Institute, which guarantees 99.982% availability and requires redundant power and cooling paths. The data centre is also ISO 27001, ISO 9001, ISO 14001, ISO 50001, and ISO 27018 certified, plus holds the ENS (Esquema Nacional de Seguridad, the Spanish National Security Scheme) certification. That last one is relevant if you’re hosting anything for Spanish public institutions or regulated sectors.

Arsys also carries Gaia-X accreditation, which positions it within the European sovereign cloud framework. For most readers, that’s background noise. For Spanish businesses with data sovereignty requirements, it’s a genuine differentiator.

Shared Hosting Plans and Pricing

Arsys sells three shared hosting plans. The entry price looks competitive. What you need to pay attention to is what happens after the first year, because the renewal jump is steep on two of the three plans.

All prices below exclude VAT. Spanish VAT at 21% applies to purchases, which means what you actually pay is higher than the figures listed. All plans are billed annually to access these rates; monthly billing is available at a higher price.

The Professional plan’s renewal is a 72% increase. That’s noticeable but not unusual in this industry. The Advanced Linux renewal is a 148% increase, from €6 to €14.90. Unlimited Linux goes from €10 to €29.90, a 199% jump. If you’re budgeting based on the intro price, you’re setting yourself up for a shock. Our guide to renewal pricing explains why this happens and what to watch for.

All three plans include a free domain for the first year, a free SSL certificate, SSD storage, unlimited traffic, HTTP/2, DKIM, DMARC, and SPF for email, and 24/7 support. There’s also a 30-day money-back guarantee across the board.

A few limitations worth knowing before you sign up. The Professional plan gets you only one website, one MySQL database, 10GB of storage, and five email accounts. The Advanced plan also limits you to one website, despite the jump to 60GB storage and 60 email accounts. Only the Unlimited plan opens up multidomain hosting, at an extra €8 per month. Backups are an optional paid add-on on all shared plans, not included by default.

Worth noting for developers: Windows hosting is available on the Advanced and Unlimited plans. That’s not something many hosts offer at the shared level, and it’s useful if you’re running .NET applications or working with Microsoft SQL Server databases.

What you won’t find on any Arsys shared plan is a one-click installer like Softaculous, or a built-in site builder. WordPress can be installed manually, and Arsys lists compatibility with WordPress, Joomla, and PrestaShop. But if you’re used to clicking “Install WordPress” from a dashboard and being done in two minutes, this host will require a bit more setup.

VPS Hosting

Arsys offers a solid range of VPS plans built on KVM virtualisation, NVMe SSD storage, and 1Gbps bandwidth. All plans include root access, a KVM console, IPS/IDS protection, DDoS protection, 10GB of free backup storage, and a 99.90% uptime SLA. Plesk is available as an optional add-on at €5 per month. Linux and Windows Server 2022/2025 are both supported.

The annual pricing gives a meaningful saving over monthly billing, particularly on the larger plans.

Standard VPS plans use data centres in Spain only. If you need your VPS in Germany, the UK, France, or the USA, Arsys offers VPS Multi, which adds multi-server management, private networks (VLAN), load balancers, and server cloning. That product sits closer to a cloud infrastructure offering than a standard VPS, with a 99.98% uptime SLA and VMware as the hypervisor rather than KVM.

One feature worth calling out: VPS plans from 120GB upward include optional self-hosted n8n, pre-installed and ready to run. If you’re using n8n for workflow automation, running it on your own VPS rather than paying for a cloud subscription keeps your data local and your costs predictable.

Dedicated Servers

Arsys dedicated servers use a pay-per-use model rather than fixed monthly plans. You configure the server you need through their control panel and pay for the resources you actually consume, billed monthly with no fixed term. There’s a 30-day free trial to test the setup before committing.

Arsys doesn’t publish fixed dedicated server prices because the cost depends on your hardware configuration, operating system choice, and any add-ons like Plesk (€5/month) or additional backup storage. The configured server includes Intel, AMD, and ARM CPU options, NVMe or SSD storage, 1Gbps bandwidth with unlimited traffic (upgradeable to 10Gbps with 25TB included), root access, VNC console, and IPS/IDS security.

The data centre selection for dedicated servers is more flexible than for VPS. You can place your server in Spain, Germany (Baden-Baden or Berlin), France, the UK, or the USA. That makes dedicated the right tier if you need European data residency outside Spain or a US presence under the same provider account.

The pay-per-use billing model is more transparent than it sounds. The Arsys control panel shows a real-time cost estimate and a billing breakdown so you always know what you’re spending before the monthly invoice arrives.

Reseller Hosting

Arsys calls its reseller product Cloudwebs. There are two versions: Shared Cloudwebs runs on shared infrastructure, while Dedicated Cloudwebs gives you dedicated hardware resources for your client sites.

Both plans include white-label control panels you can brand with your own logo and colours, customisable DNS nameservers, unlimited traffic, SSL certificates, and a free mail migrator. Dedicated Cloudwebs includes hardware options from 250GB/2CPU/8GB RAM up to 1TB/8CPU/16GB RAM.

Pricing scales with usage. Domains beyond the included 30 start at €2 each and fall to €0.50 above 201. Mailboxes beyond 800 are available in blocks, with the per-unit cost dropping as volume increases. For a web agency managing dozens of client sites, the white-label setup and flexible resource scaling are the main draws here.

Business Email and Microsoft 365

Arsys sells business email as a standalone product, which is useful if you want professional email but aren’t ready to commit to a hosting plan. The Arsys Email plan starts at €1 per month for the first year (5 users) or €2 per month (20 users), renewing at €4 and €6 per month respectively.

Each mailbox gets 10GB of storage, separate from any web hosting storage. All plans include antivirus and antispam filtering, DKIM/DMARC/SPF support, SSL/TLS access, RoundCube webmail, and 5GB of email backup. One feature that stands out is Arsys’s hybrid email system: you can mix standard IMAP mailboxes and Microsoft Exchange mailboxes on the same domain. That lets you give Exchange functionality to the people who need it without paying Exchange prices across the whole organisation.

For businesses that want the full Microsoft stack, Arsys resells Microsoft 365 directly.

All M365 plans include a 30-day free trial and a free domain for the first year. Business Basic adds Teams and web-based Office apps. Business Standard includes the full installable desktop suite across five PCs or Macs, five tablets, and five smartphones per user. All prices exclude VAT.

Having hosting, email, and Microsoft 365 under one Spanish provider with a single support line is a genuine convenience for businesses that don’t want to manage multiple vendor relationships.

Performance and Uptime

Arsys publishes a 99.90% uptime SLA on shared hosting and standard VPS plans, rising to 99.98% on VPS Multi and cloud servers. The Tier III certification on the Logroño data centre independently validates the infrastructure redundancy behind those numbers: Tier III requires dual power paths, redundant cooling, and maintenance capability without service interruption.

One practical point for anyone targeting Spanish search traffic: Arsys hosting uses Spanish IP addresses, and the company explicitly notes this as an SEO advantage for sites targeting Spanish audiences. Search engines do weight server location as a local relevance signal, so hosting a Spanish-market site on Spanish IPs is a minor but genuine benefit that most international hosts can’t replicate without using a Spanish CDN edge node.

We weren’t able to run independent speed or load time tests for this review. The performance and uptime claims above come from Arsys’s published SLAs and infrastructure documentation. If you want to test server response times before committing, our Server Response Time Tester lets you do that for free.

Security and Certifications

The security stack across all Arsys plans includes IPS/IDS intrusion detection, a WAF (web application firewall), DDoS protection, and a perimeter firewall. SSL certificates are included on all shared plans, and TLS encryption is enforced on email connections.

The certification list is longer than most hosts at this tier. ISO 27001 covers information security management. ISO 14001 and ISO 50001 cover environmental and energy management systems. ISO 27018 covers protection of personal data in cloud environments. The ENS certification is specific to Spanish data protection law and relevant for any organisation handling Spanish citizen data or working with public sector clients. Gaia-X accreditation places Arsys within the European sovereign cloud initiative.

On the shared hosting control panel: Arsys uses a proprietary panel, not cPanel or Plesk. On VPS and dedicated servers, Plesk Obsidian is available as an optional add-on at €5 per month.

Customer Support

Arsys offers 24/7 phone, live chat, and email support. The company claims a sub-one-minute phone response time, and the Trustpilot reviews from long-term customers (Arsys has been operating since 1996, and some reviewers mention 20 or 30 years with the provider) broadly back up that claim for phone and chat.

The honest caveat is language. Support is primarily Spanish-speaking. English assistance is available, but some of the Arsys website reverts to Spanish in places, and the knowledge base is more comprehensive in Spanish than in English. If you’re running a Spanish-language business, this isn’t a problem. If you’re an international developer who needs English-language technical support at midnight, you may hit friction.

Who Should Use Arsys?

Arsys makes the most sense for Spanish businesses and agencies that want local infrastructure, Spanish-language support, and the peace of mind of knowing their data stays in a Tier III certified facility in Spain. The combination of hosting, business email, and Microsoft 365 under one provider is a genuine convenience for SMBs that don’t want to juggle multiple vendor relationships. Web agencies will find the Cloudwebs reseller product well-suited for managing multiple client sites under their own brand, and the hybrid Exchange/IMAP email setup is a smart solution for teams that don’t need full Exchange across the board.

It’s a harder sell for English-speaking users who want a polished beginner experience, or for WordPress users who expect a one-click installer and automated backups as standard. Hostinger, SiteGround, or Namecheap will serve those use cases better. Arsys is a business tool built for a specific market. Within that market, it’s among the strongest options available.

Frequently Asked Questions

Who owns Arsys?

Arsys is owned by the IONOS Group SE, the European hosting and cloud division of United Internet AG. Arsys has been part of the group since 2013. It operates independently under its own brand with its own data centre in Logroño, Spain.

Does Arsys include a free domain?

Yes. All shared hosting plans, the business email plan, and Microsoft 365 plans include a free domain for the first year. The promotion covers .com, .es, .net, .org, .eu, .info, and several other extensions. After the first year, the domain renews at standard rates.

Is Arsys good for WordPress?

Arsys supports WordPress on all shared hosting plans with PHP, MySQL, and .htaccess. The limitation is that there’s no one-click installer: you’ll need to install WordPress manually. If that puts you off, look at hosts with Softaculous or a built-in WordPress installer instead.

Does Arsys have a money-back guarantee?

Yes, 30 days on shared hosting, VPS, and dedicated servers. If the service doesn’t meet your expectations within that period, they’ll refund your money without questions.

Is Arsys available in English?

The main Arsys website (arsys.net) is available in English, Spanish, and Portuguese. Support is available in English, but is primarily staffed for Spanish speakers. Some sections of the knowledge base and control panel are more thoroughly translated than others.

Final Verdict

Arsys occupies a specific and well-defined position in the hosting market: the go-to provider for Spanish businesses that want local data sovereignty, Tier III certified infrastructure, and a single vendor for hosting, email, and Microsoft 365. In that role, it’s genuinely hard to beat. The data centre credentials are real, the certification stack is among the most thorough in this market, and the 30-year track record speaks for itself.

The weaknesses are equally specific. The renewal pricing on the Advanced and Unlimited shared plans is punishing, the absence of a one-click installer is a real friction point for beginners, and the English-language experience is noticeably thinner than the Spanish one. If you’re not targeting a Spanish-speaking audience, most of the advantages that make Arsys stand out simply don’t apply to you.

For a Spanish-market business, agency, or developer: 4.0/5. For everyone else: look at IONOS, Hostinger, or SiteGround first.
