The Situation

Why fixed on-site guarding doesn't make sense for every property

Not every property needs continuous presence – but every property needs regular checks:

01

Fixed guarding is often uneconomical

When the risk is moderate but not zero, round-the-clock guarding is often disproportionately expensive for the actual need.

02

Missing checks go unnoticed

Without regular patrols, you often only notice a problem once it has already caused damage.

03

Multiple sites overwhelm in-house staff

Managers with multiple properties rarely have the capacity to regularly check every site themselves.

The Black Graben Approach

Mobile patrols instead of fixed posts

Our mobile patrol and lockup service offers more than just a visible security presence – it's a proactive solution for early detection and prevention of risk. Through regular checks, quick responses and targeted measures, we ensure properties, grounds and people are optimally protected at all times.

A single route can cover multiple properties – you pay for checks, not for uninterrupted presence at one location.

Mobile patrols instead of fixed posts

Regular checks, without the cost of continuous on-site guarding.

Multiple properties on one route

Efficient coverage of multiple properties through a coordinated patrol route.

Rapid response to anything unusual

Immediate action whenever a check reveals something out of the ordinary.

Documented checks

Every patrol is traceably logged – for you and your insurer.

„Non sine periculo“
Not Without Danger

Four elements define a true professional in the security industry: formal education, continuous training, extensive experience, and unwavering commitment.

Frequently Asked Questions

Common questions about the mobile patrol service

How often is each property checked?

We set that individually based on risk level – from multiple checks per night to targeted spot checks.

How many properties can this cover at once?

The patrol service is scalable – from a few to many distributed properties on one coordinated route.

What's the difference from fixed on-site guarding?

The mobile patrol service is significantly more cost-efficient for properties that don't need continuous presence, but do need regular, documented checks.
