Physical Data Center Security: From Certifications to Access Controls
Physical Data Center Security
There is a deeply rooted false myth in the modern IT world: the idea that the “Cloud” is an ethereal, intangible entity floating in the digital ether. The reality is quite different and decidedly “heavier”: the cloud rests its foundations on tons of iron, kilometers of fiber optic cables, thick reinforced concrete walls, and strict military-grade surveillance protocols. Today, the foundation of corporate IT systems must be unassailable. Choosing where and how to host business-critical processes is no longer just a matter of network performance or pure computing power, but a vital strategic decision that impacts legal compliance and the very survival of the company.
Through structured and technologically advanced providers, organizations can finally delegate the burden and exorbitant costs of direct infrastructure management without giving up control. Today we will take a real “dive” behind the scenes of Servereasy, exploring the walls and engineering of the Datacenter (DC1) in Settimo Milanese to understand exactly how the beating heart of Italian companies is armored and what standards separate an enterprise infrastructure from an amateur solution.
Why is data center security important?
In today’s digital landscape, cyber risk doesn’t just come from software-based hacker attacks. There is a physical, environmental, and infrastructural risk that is equally lethal. Prolonged downtime represents incalculable economic damage, loss of market reputation, and often heavy regulatory fines. From small SMEs to large enterprise companies, corporate data protection can be guaranteed at the highest level only by relying on an infrastructure that is not only fast, but solid, certified, and inherently resilient to any type of external shock.
Furthermore, a crucial geographic and geopolitical factor emerges in the GDPR era: data sovereignty. Relying on massive public cloud giants often means not knowing exactly in which European (or non-European) country your customers’ backups physically reside. Choosing a provider with proprietary data centers on Italian territory guarantees total geographic control of information. Keeping data in our country ensures full compliance with the General Data Protection Regulation, avoiding the heavy legal pitfalls related to the export of sensitive information, while ensuring lightning-fast navigation for national users thanks to reduced network latency times (5-15ms).
How does data center security work? (Focus on the Milan Bunker)
Physical security is the indisputable and non-negotiable prerequisite for any logical security. No next-generation firewall will ever protect a server if someone can simply enter the data room and pull the plug or take the hard drive. The Servereasy Datacenter (DC1) in Settimo Milanese was created precisely to eliminate these risk vectors. Being a proprietary building, the company has millimeter control over access procedures and long-term structural investments.
Located just a few minutes from the Via Caldera 21 campus (the most important internet exchange node in Italy), DC1 demonstrates that true data center security begins with the implementation of strict engineering security measures, designed to minimize any interruption. Access controls include multiple perimeters, biometric identification, punctual registration of every entry, and 24/7/365 closed-circuit video surveillance.
The DC1 is interconnected via 2 Dark Fibers with physically and geographically diversified paths to Via Caldera, nullifying the risk of a single point of failure. To these, an additional Dark Fiber link to Data4 is added.
Logical Data Center Security: Managed Virtual Datacenter Solutions
Compared to old and rigid on-premise infrastructures, the modern cloud offers absolute operational agility. The physical data center in Milan hosts clusters designed to deliver scalable computing power, allowing the customer to focus exclusively on their software workloads while delegating hardware management.
The pillars of logical continuity for these solutions include:
- Hyperconverged Platform: The ecosystem is based on powerful clusters built with the Proxmox virtualization environment and associated with Ceph distributed storage.
- High Availability (N+1): In the event of an irreversible failure on a physical server, virtual machines are automatically migrated and restarted on active, healthy cluster servers in moments, without data loss.
- Proactive Backup and Monitoring: The virtual infrastructure is constantly supported by a strict centralized backup system, ensuring that data backup is always consistent and easily recoverable.
| Critical Component | Servereasy Datacenter (DC1) | Operational Advantage |
|---|---|---|
| Architecture and Design | Designed with Tier 3 standards (Tier 4 ready) | Concurrent Maintainable configuration: all maintenance is performed without any service downtime. |
| Power Continuity | UPS 2N (Feed A+B) + 250 KVA Diesel Generator | Uninterrupted resilience against national public grid blackouts. |
| Environmental Control | N+1 direct free cooling with cold aisles | Energy efficiency (ISO 14001) and absolute prevention of rack overheating. |
| Structural Capacity | 1500kg/sqm raised floor | Base designed to support ultra-high density rack cabinets. |

Data Center Quality Certifications
In today’s market, indisputable regulatory evidence is needed to pass strict corporate audits. Servereasy has an array of international certifications:
- ISO/IEC 27001:2022 (with 27017 and 27018 extensions): The global excellence for Security Systems. The integration of extensions for cloud service security (27017) and personal data protection (27018) establishes total compliance with the GDPR.
- NIS2-Ready (Legislative Decree 138/2024): Relying on Servereasy provides the technical and documentary foundation already aligned with NIS2, essential for demonstrating the security of your digital supply chain during an audit.
- ISO 9001:2015 and ISO 14001:2015: Standards that guarantee verified intervention processes to ensure SLAs (9001) and focus on reducing environmental impact (14001).
The importance of disaster recovery: Geo-redundancy in Florence
No corporate disaster recovery plan can be defined as structured if it does not consider the hypothesis of severe natural disasters or extensive territorial blackouts. For enterprise realities, implementing a geographically distributed disaster recovery strategy is the only way to protect the business.
Servereasy responds to this need by providing a proprietary secondary Datacenter in the province of Florence. This dual localization allows IT Managers to structure solid and timely recovery plans, replicating virtual machines hundreds of kilometers from the main headquarters to ensure that critical services never stop.

What does the Tier 3 standard guarantee in a physical data center?
It guarantees an architecture designed for the absence of single interruptions. Equipped with multiple paths for power and cooling, it allows maintenance on any machinery without having to interrupt service delivery.
Is my company's sensitive data protected according to GDPR requirements?
Yes. In addition to ensuring servers remain in Italy, the entire Cloud infrastructure has achieved ISO/IEC 27018:2020 certification, the highest international standard for personal data protection in cloud environments.
How do you handle large-scale electrical blackouts in the Milan area?
The data center immediately isolates interruptions from the public grid. A 2N UPS system intervenes to support the critical electrical load, simultaneously starting the powerful proprietary 250 KVA diesel generator.
Does the cloud service prevent machine downtime in the event of hardware failures?
Yes. Thanks to the architecture developed in High Availability (N+1), when a physical component breaks, the affected virtual machines are immediately migrated and restarted on the remaining operational servers.
Is your infrastructure suitable to help a company demonstrate compliance with the NIS2 Directive?
Absolutely yes. Servereasy positions itself as a “NIS2-aligned” partner, supported by rigorous certifications such as ISO/IEC 27001:2022, which provide the documentary evidence to legally validate the resilience of the IT supply chain.
