What is a fire- and burglary-resistant safe?

A fire- and burglary-resistant safe is a security solution that protects valuables against both theft and fire.

Dual certification means that the safe has been independently tested and approved for both aspects:

  • Burglary resistance

    • Security Level S1 / S2 (EN 14450) → entry-level models, suitable for limited values and private use.

    • Grades 0 to VI (EN 1143-1) → professionally certified safes, with increasing resistance to burglary attempts. The higher the grade, the higher the insurable value.

  • Fire resistance
    Tested separately (for example according to EN 15659 or NT FIRE 017) and ranging from 30 to 120 minutes of protection.
    Note: there is an important difference between the protection of paper documents and that of digital media (hard drives, USB sticks, etc.), as digital data is damaged at much lower temperatures.

Only safes with dual certification provide truly tested and reliable protection against both fire and burglary.

A burglary-resistant safe (or strongbox) is a security cabinet specifically designed to withstand burglary attempts. These safes are tested according to the European standard EN 1143-1, which measures resistance against attack methods such as drilling, grinding, prying and thermal tools.

Based on these tests, safes are assigned a security grade (resistance grade):

  • Grade 0 to VI → standard safes, suitable for private and professional use

  • Grade VII to XIII → vault rooms and high-security installations

These safes are often also referred to as Eurosafes, as they are built and certified according to harmonised European standards.

The right grade depends on the value stored, the risk profile and insurance requirements. For professional use, Grade III to VI is often required.
