Safer space through planning.
Over 25 years of experience in spatial crime prevention, technical burglary protection and standards-compliant vehicle access protection — for municipalities, associations, businesses and event organisers.
Advice that works in practice.
Spatial crime prevention is internationally recognised as one of the most effective strategies. It does more than reduce opportunities — it shapes public spaces so that people feel safe and security becomes measurable.
Consultancy for municipalities
Crime-prevention advisory opinions in urban land-use planning, safer-neighbourhood concepts, hot-spot analysis, crime mapping. Support from planning through implementation — including measures eligible under the KfW IKK 208 funding programme.
Consultancy for associations
Expert support for industry associations, contribution to standards and guidelines, training concepts and presentations — from DIN SPEC 91414 to municipal prevention work.
Consultancy for businesses
Technical burglary protection since 1995 — against break-ins, theft, robbery and threats. Includes staff training on handling aggressive individuals.
Consultancy for the home
Honest, manufacturer-independent recommendations for living spaces. What actually works, what is a waste of money — and what fits your daily routine.
Six considerations before every access-protection concept.
A concept that merely simulates a sense of security undermines credibility. Every project therefore follows a clear sequence — from threat situation through to standards-compliant product selection.
Preparation
Identify the threat situation and weigh the consequences of action against those of inaction.
Hazard analysis
Visitor numbers, VIP status, cultural context, significance of the location — the consequences of a possible vehicle ramming attack must be given due consideration.
Protection objective
Define precisely what the access-protection concept is meant to achieve — for example, preventing the uncontrolled entry of heavy vehicles.
Vulnerability analysis
Determine and delimit the protection zone (perimeter). Rescue and escape routes as well as essential access ways are integrated, not ignored.
Protection concept
Standards-compliant elaboration to ISO IWA 14-2: offender behaviour, access points, routes — and the expected attack forces are calculated.
Product selection
Concrete product requirements emerge from the calculated impact loads. Only certified products tested to international standards qualify.
Cityscape-compatible. Standards-compliant. Calculated.
Protection against vehicle ramming attacks does not begin with bollards but with analysis. Together with planning offices, security providers and municipalities we develop concepts that are viable in public space — in design, in law, and in technology.
Calculation and documentation: digital, audit-ready, vendor-neutral.
The ViaGuardium software translates our methodology into a map-based workflow: impact energy, momentum and velocity per access point — calculated automatically, AI-assisted threat analysis, audit-ready PDF reports. The calculation foundations follow current DIN and ISO standards; recommendations remain vendor-neutral.
Christian Weicht also oversees the Vehicle Access Protection product list published by the Crime Prevention Office of the German Police (ProPK) — the technical interface between manufacturers, police, and users.

Practice meets science.
Since late 2019 I have led, together with criminologist Detlev Schürmann, the research division Applied Crime Prevention and Accompanying Scientific Research at the Chair of Architecture and Visualisation (Prof. Dominik Lengyel) of BTU Cottbus-Senftenberg — the only research division of its kind nationwide at an architecture chair.
Protecting public spaces
Initiated after the 2016 Berlin Breitscheidplatz attack. With financial support from the Federal Ministry of the Interior (BMI) and in cooperation with ProPK, two DIN standards, a guidance document for municipalities, and the Vehicle Access Protection product list emerged.
Digital twins
Numerical simulation of vehicle attacks — impact energy and deformation behaviour can today be calculated on the model, replacing costly real-world testing. Presented at the 2nd Vehicle.Security.Barrier.Conference Münster (09/2024).
Crime-prevention product design
How can street furniture, building components and products be designed so that they reduce crime opportunities — without being perceived as security technology? A dedicated research line at the BTU division.
Crisis Prevention
Regular contributions to the trade magazine Crisis Prevention (CPM Verlag) — most recently „Vehicle access protection of public spaces against ramming attacks“ in issue 4/2025, plus a profile feature on the BTU research division in 4/2024.
Sponsors and partners: Federal Ministry of the Interior (BMI) · German Research Foundation (DFG) · Crime Prevention Office of the German Police (ProPK) · BTU Cottbus-Senftenberg.
Spatial crime prevention — from practice, for practice.
For over 25 years I have been working on how crime is shaped by spatial design. It became clear to me early on that spatial crime prevention can do far more than merely avoid or remove fear-inducing places.
Today, spatial crime prevention is internationally recognised as one of the most successful and effective strategies. Avoiding and resolving spatial crime problems is one of my core competencies.
On the following pages you will find strategies and information on how spatial crime prevention can be applied effectively, and how I integrate it into planning processes. Please get in touch — I am happy to answer questions or hear suggestions.
Yours, Christian Weicht
