In a world where security faces increasingly sophisticated threats, a unique solution emerges: the most secure safe on the planet. Manufactured exclusively by Arcas Gruber and certified with the highest European standard Grade 9 UNE-EN 1143-1, it is engineered to withstand mechanical, thermal, and explosive attacks, as well as extreme disaster scenarios. More than just a safe, it is a fortress of trust for those who demand total protection against unimaginable risks.
On this page, you will discover why this safe represents the highest level of physical security: the certification process, the advanced multilayer materials, cutting-edge locking systems, real-world applications, and the customization options that make it the ultimate choice for maximum protection.
What does Grade 9 UNE-EN 1143-1 mean?
The UNE-EN 1143-1 standard is the European benchmark that classifies the resistance of safes and vault doors against burglary attempts. It ranges from lower grades up to Grade 9, which represents the highest commercial level of certification recognized under this standard. Achieving Grade 9 requires extraordinary performance against a wide range of threats, including mechanical tools, high-powered drills, thermal lances, and explosives.
A safe that has passed Grade 9 testing has demonstrated its ability to withstand the most extreme attack scenarios carried out under laboratory conditions by expert technicians. The result is a guarantee that no conventional burglary attempt can compromise its integrity.
Beyond the body and the door, the standard also examines locks, bolting systems, and anchoring points. In Grade 9 safes, the use of EN 1300 Class C locks—the highest lock classification available—is mandatory, along with the integration of advanced anti-drilling, anti-extraction, and anti-explosion devices.
Protection against extreme threats
Arcas Gruber Grade 9 safes are designed to perform beyond conventional burglary resistance, addressing extreme scenarios such as:
- High-powered explosives: tested with controlled charges to ensure the structure, door, and bolts remain intact.
- Thermal protection: special refractory compounds resist cutting torches and thermal lances at temperatures above 1,000 °C.
- Extreme impacts: structural reinforcement withstands heavy machinery or falling masses without compromising security.
- Nuclear scenarios: thanks to their density and multilayered shielding, they provide exceptional resistance to shockwaves and radiation exposure. While no system can guarantee total protection against a direct nuclear strike, a Grade 9 safe offers unparalleled resilience under catastrophic conditions.
- Natural disasters: resistance to extended fires, floods, building collapses, and extreme environmental conditions.
These capabilities make the Arcas Gruber Grade 9 safe the most reliable solution for securing assets in environments with extraordinary risks.
Next-generation materials
The construction of a Grade 9 safe combines bimetallic high-strength steel, special refractory concrete, metallic fibers, and advanced anti-drill layers. Each material has a specific role within a multilayer system engineered to stop any type of intrusion or destruction attempt.
The exceptional wall and door thickness, combined with strategic reinforcements, transform these safes into true strongholds capable of withstanding the most advanced attacks.
Advanced locking systems
To comply with Grade 9 requirements, the locking system must meet the strictest international standards. All units are equipped with EN 1300 Class C certified locks and can be configured with:
- Dual control systems requiring two independent keys or codes.
- Programmable time delays to deter forced openings.
- Redundant electronic locking for operational security.
- Biometric systems including fingerprint, iris, or facial recognition.
This combination not only prevents manipulation but also adds time and complexity, deterring even highly qualified attackers.
Who needs the world’s most secure safe?
Grade 9 security is not a luxury; it is a necessity for organizations and individuals protecting irreplaceable values. Typical users include:
- Banks and financial institutions: secure storage for cash, bullion, and critical documents.
- Museums and art galleries: protection of priceless works of art against theft and destruction.
- Research laboratories: safeguarding sensitive data, restricted materials, and prototypes.
- Government and military institutions: protection of classified information and strategic resources.
- High-profile residences and private bunkers: maximum protection for jewelry, collections, digital media, and family assets.

Frequently Asked Questions
What insured value does a Grade 9 safe cover?
Across Europe, insurance companies recognize Grade 9 as the highest standard, enabling coverage of exceptionally high-value assets.
Can a Grade 9 safe resist a nuclear explosion?
No system can guarantee absolute protection against a direct nuclear strike. However, its density and multilayered shielding provide extraordinary resistance to radiation, shockwaves, and catastrophic scenarios.
Can biometric systems be integrated?
Yes. Fingerprint, iris, and facial recognition systems can be installed, provided they comply with EN 1300 Class C requirements and best cybersecurity practices.
What is the difference between a Grade 7 and a Grade 9 safe?
While both are high-security solutions, Grade 9 surpasses Grade 7 in resistance times, tool categories tested, and the level of insured value allowed by most policies.
Can Arcas Gruber Grade 9 safes be customized?
Yes. Each unit is made to order with options for size, interior configuration, finishes, locking systems, and advanced monitoring—all while maintaining certification integrity.
