SR 1: Opportunist attack by bodily force using minimal tools (e.g. screwdriver, knife, pliers, etc.).
SR 2: More determined opportunist attack with tools of a higher mechanical advantage (e.g. SR1 tools plus bolt cutters, claw hammer, drill, etc.).
SR 3: Deliberately forced entry of protected premises using bodily force and a selection of attack options (e.g. SR2 tools plus short axe, chisels, crowbar, gas torch, etc.).
SR 4: Experience attempts at forced entry with higher tool levels (e.g. SR3 tools plus felling axe, sledgehammer, steel wedges, disc grinder, jigsaw, etc.).
SR 5: Serious attempts at forced entry with top-end battery power tools used by fire and rescue teams (e.g. SR4 tools plus circular saw and the awesome 750W reciprocating saw with specialist blades). This is a massive step up in protection level from SR4 – using state-of-the-art cutting tools. However, these tools are readily available to anybody with serious intent.

These tests are carried out by an accredited organisation with full knowledge of the product and its construction. Many initial trials are carried out to assess the best tools to use from the allowable toolset. The ratings are achieved by combinations of materials within the core. Ratings will be indicated in ‘as built’ drawings and certified by the independent LPCB ISO9001 audit process.

PUE is an important measurement of energy efficiency in Data Centres, providing the metrics needed to make informed green efficiency changes in Data Centre infrastructure. With the cost of power rising, an efficient Data Centre Design not only delivers cost benefits to your organisation but is considerably less damaging to the environment.


Whether traditional, containerised or modular our energy-efficient scalable approach to any challenge is developed to align with the overall strategy of each business client, ensuring we optimise every data centre design and future fit-out at every stage.

Costs can vary widely based on the size, location, technologies used, and other factors. We recommend reaching out with specific project details for a tailored estimate.
We would like to thank Secure I.T. Environments for delivering during a challenging time, as well as in a short turnaround. We are very pleased with the results
Our migration went smoothly and we went live in the new location as planned on the Monday morning. Thanks to the careful planning of Trust IT projects and estates teams, working in close partnership with Secure I.T. Environments, we were able to plan for the challenges of working on a tight timeline.
