In an increasingly complex world, the demand for effective security solutions is growing – particularly in environments where people, assets, and sensitive information need safeguarding. The Lindner Group offers bespoke ballistic protection systems that combine cutting-edge technologies with certified safety, while also allowing design flexibility. Our solutions can be seamlessly integrated into a wide variety of building types – from prestigious reception areas to high-security private zones.

Our systems are tested in accordance with DIN EN 1522 / VPAM standards and represent uncompromising reliability. They can be seamlessly integrated into any building structure, offering maximum design flexibility – for security that adapts to your architectural vision.

Lindner Group’s ballistic-resistant doors can be designed to be multifunctional on request. They combine verifiably tested resistance with intelligent features - ranging from access control and panic functions to emergency exit solutions. In doing so, they become a central component of a comprehensive security concept.

Our systems go beyond ballistic resistance and can be combined with additional features such as burglary protection, radiation protection, or impact resistance. This creates bespoke security solutions that comprehensively and sustainably protect people, assets, and buildings.
Whether in government buildings, courthouses, banks, research facilities, or particularly sensitive corporate areas, our ballistic-resistant solutions help to minimise risks effectively and provide reliable protection against firearm threats. In particular, they offer targeted defence against attacks with handguns, in accordance with the applicable ballistic resistance classes defined by DIN EN 1522/1523 or VPAM.
The Lindner Group’s security solutions are based on precisely engineered materials and carefully considered designs. Our products are tested under realistic conditions and meet the highest standards and requirements. Whether wall, door, window, or facade elements, our ballistic-resistant systems integrate seamlessly into existing architectural concepts, combining dependable protection with sophisticated aesthetics – without compromise.
A key component of our comprehensive protection concept is our ballistic-resistant doors. They serve not only as robust physical barriers but also stand out for their verifiably tested resistance to gunfire in accordance with the recognised European standards DIN EN 1522/1523. This ensures that our door systems deliver the precise level of protection you can rely on in critical situations.
Our doors are available in various resistance classes – from FB1 to FB4NS (non-fragmenting) – and can be tailored to meet specific security requirements. They are therefore suitable for use in sensitive corporate areas, public institutions, or private properties. At the same time, we always take architectural considerations into account, ensuring that functionality and design form a seamless whole.


Ballistic-resistant glazing plays a central role in firearm protection, with requirements defined in DIN EN 1063. This standard specifies the testing procedures and classification of safety glazing designed specifically to provide protection against gunfire.
Resistance classes are determined based on the type, calibre, and weight of potential projectiles. A crucial criterion is that no projectile may penetrate the protected area. It is not sufficient for the glazing alone to be resistant – the frame and joints must also be constructed to ensure protection is reliable and comprehensive.
