Sarenet

Sarenet is a Spanish business connectivity, cloud, voice, and cybersecurity provider headquartered in Zamudio, Bizkaia. Founded in 1995, the company positions itself as a specialist in Internet and telecommunications services for businesses, with a long-standing focus on secure connectivity, cloud infrastructure, private networking, voice services, and managed security. Its current public positioning emphasizes direct technical support, tailored enterprise solutions, and a domestic cloud model based on data centers located in Spain.

⚙️ Facility Highlights

Data Center Footprint:

Sarenet publicly positions its cloud platform around data centers located exclusively in Spain, and its cloud and backup materials state that its data centers are distributed across Spanish geography rather than abroad. Its marketing materials further describe a domestic “cloud de proximidad” model designed to keep customer data within Spain.

Public Sarenet materials and company-linked landing pages reference data center presence in Barcelona, Bizkaia, Madrid, and Valencia, while a 2025 Sarenet press release states the company is investing in a new data center in Derio, Bizkaia as its ninth data center in Spain. Baxtel also lists two Zamudio facilities under Sarenet and identifies one of them as a site in the Derio area of Bizkaia.

Facility Design & Infrastructure:

Sarenet’s housing materials position its facilities as professional environments for hosting physical customer servers, with messaging centered on security, uninterrupted power, climate control, and high availability. Its cloud marketing also describes redundant Spanish data centers, redundant storage, and domestic hosting intended to reduce latency and support data protection requirements.

A 2025 report on the Derio project adds more specific infrastructure detail, stating the new facility is planned with 3 MW of capacity, 100% renewable energy, and connectivity to the Telxius communications hub in Derio. Baxtel’s listing for Sarenet: Zamudio 2 describes a facility of about 1,000 square meters designed to support up to 340 racks.

Service Portfolio Overview:

Sarenet publicly markets services across connectivity, cloud, cybersecurity, voice, IoT, and IT management, with cloud offerings that include equipment hosting, virtual machines, private virtual data center, backup, disaster recovery-oriented cloud protection, and connections to public clouds such as Amazon, Azure, and IBM. Its cloud materials also reference IaaS, PaaS, SaaS, hybrid cloud, and cloud-based application delivery.

Its security-cloud and backup pages add evidence for managed cloud security, including firewalls, anti-DDoS, WAF, automatic backups, and remote backup based on Veeam. Sarenet also states that it is a Veeam Cloud Provider in its cloud marketing materials.

🔐 Security & Compliance

Infrastructure Resilience:

Sarenet’s public cloud materials emphasize maximum availability, redundant storage between data centers, and robust contingency positioning for critical events. The company’s 2025 anniversary release frames its infrastructure as supporting strong contingency plans for events such as outages and natural disasters.

Its backup page also states that Sarenet’s data centers are located exclusively in Spain and comply with ISO 27001 and the ENS, tying resilience and domestic hosting to formal security controls.

Physical & Logical Security:

Sarenet’s housing, backup, and cloud-security materials describe environments built around professional supervision, security measures, and managed protection for hosted systems. The company publicly references constant surveillance, multiple security measures, firewalls, threat detection, DDoS mitigation, and specialist-managed protection for cloud environments.

A 2024 Sarenet SOC press release also states that its SOC team is staffed by qualified personnel certified by leading vendors and aligned with ENS and ISO 27001 standards, reinforcing the company’s published security operations posture.

Compliance & Standards:

Sarenet publicly cites compliance with ISO 27001 and the Esquema Nacional de Seguridad (ENS) across its data center and backup positioning. Its certifications pages and related materials present quality, security, and compliance as part of the company’s service guarantees for business customers.

🌐 Connectivity & Carrier Access

Carrier Neutrality:

Sarenet’s public positioning is built around its own network, business Internet services, and dedicated private connections between customer sites, Sarenet-hosted systems, and public cloud platforms. Its published materials emphasize control, proximity, and direct connectivity rather than a neutral-facility narrative.

Network Capabilities:

Sarenet publicly markets dedicated fiber, private virtual networks, VPN MPLS, SD-WAN, line backup, secure cloud access, and direct enterprise connectivity to hosted systems and public cloud platforms. Its MPLS and SD-WAN pages position these services for secure multi-site connectivity, mobility, and application access.

Its cloud-connectivity pages also reference direct and dedicated access, private access to critical hosted systems without traversing the public Internet, and private connections to public clouds. In cloud marketing, Sarenet additionally references dark fiber between data centers and direct access to Azure, AWS, and IBM through dedicated circuits.

Connectivity Use Cases:

Sarenet’s published offer is well aligned to organizations needing multi-site private networking, Spain-based hosting, private access to hosted workloads, hybrid cloud connectivity, backup and recovery protection, and managed modernization of voice and data environments. Its own messaging is consistently aimed at business customers that want a domestic infrastructure provider with direct support and secure, customized services.

💼 Who It Serves

Sarenet explicitly positions itself as a provider for businesses and professionals, and its messaging repeatedly references SMEs, distributed organizations, and companies needing tailored connectivity, cloud, voice, and security solutions. Its 2025 press release says the company serves around 4,500 clients, with many long-standing customer relationships, and frames its mission around the digital needs of Spanish businesses.
