Five Pillars of Physical Data Centre Security

Data centres are a vital component in modern life’s reliance on the safe movement and storage of information. As well as digital breaches, these sites are also vulnerable to physical break-ins, with fences and gates providing the first line of defence against unauthorised access to servers, power generators, and other critical assets.

When protecting your data centre, we recommend addressing the following five security layers to ensure total protection at every level. This strategy should be used in tandem with the five Ds of perimeter security: Deter, Detect, Deny, Delay, Defend.

five pillars of data centre security

1. Protect the Outer Perimeter

Defending your data centre against unauthorised entry is the first step in preventing physical security breaches.


Select a product that is tested and certified to either NPSA (previously CPNI) or LPS 1175, and that withstands forced entry attempts using different tool categories. Also make sure the design fits with your security and privacy needs, as well as blending with the facility’s surroundings.

Fence spikes and security toppings such as barbed wire, spikes and rotary systems can further enhance the levels of security against intrusion, damage, acts of vandalism or terrorism but check planning restrictions in the area and be mindful of their use in residential settings. Areas with restrictions are where fencing design comes into play. To protect a data centre from the specified risks while adhering to local regulations, our Barbican Defender Xtreme A1 was installed. With cranked pales it projects a strong image with anti-climb properties, but does not create a hostile environment and fits better with the surrounding environment than barbed wire and mesh fencing.

Gates and access control

A perimeter security system should be completed with the appropriate type of gate, whether it be swinging, sliding or bi-folding. A proper gate ensures no weak points exist around the boundary, and serves as secure a checkpoint to let authorised traffic pass in and out. Combine gates with the likes of traffic arm barriers or road blockers to slow vehicles, and be sure to include pedestrian gates for safe access for staff and clients.

Hostile Vehicle Mitigation

With the rising threat of vehicle-borne attacks, Hostile Vehicle Mitigation (HVM) measures are an increasingly important aspect of any physical security strategy. Add another line of defence with unobtrusive HVM solutions such as certified crash rated bollards, barriers and road blockers. Additionally, another line of standoff fencing can be installed around the main perimeter fence. Linebacker PNR, with its natural post and rail appearance, provides an unobtrusive fence which is capable of stopping a 7.5 tonne vehicle travelling at 50mph.


CCTV cameras enable 24/7 monitoring of your facilities against potential threats. When paired with CCTV and intruder alarm systems such as PIDS which can be mounted on any stable fencing in good condition, and offer highly efficient and discreet threat detection.Data centre

2. Protect Assets Within the Perimeter

Data centres feature specialised and costly equipment such as power generators and air conditioning units, and also house staff vehicles and offices. Some considerations in monitoring and controlling movement within the zone:


Infrared or thermal detectors track movement, and combined with audio warnings issued by the CCTV operator are an efficient way to de-escalate threats.

Security Lighting

Installing security lighting systems ensures that intruders are easily detected at night. If your facility resides in an area that enforces light pollution restrictions, event-triggered lighting solutions or CCTV systems with thermal imagery capabilities could be the answer.

Noise Control

Consider controlling the noise of power generators and a/c units to keep neighbours happy by enclosing them in special sound-dampening structures like timber acoustic barriers.

3. Protect the Server Building

The third layer in data centre protection is securing the server room itself.

Fire and Intruder Alarms

These systems are vital in keeping your server buildings safe, and can link to CCTV monitoring for an extra level of security.

Key Access Point Control

Protect entry points to deny access to unauthorised personnel with turnstiles and keypad entry systems.

4. Protect the Server Rooms

Once the server rooms are breached, the data is at high risk. Some measures to consider in defending your server rooms:


Monitor the server floor with multidirectional cameras.

Audio Deterrents

Install speakers from which to issue warnings or announce to security staff that a breach has occurred.

Internal Gates and Compounds

Secure gates installed in corridors, and mesh compounds around server units are ideal for protecting critical units from sabotage.

5. Protect the Data Itself

Your final line of defence in your data centre is protecting the data racks themselves. Here are some controls to consider:

Monitor Cabinet Doors

Install camera systems within the racks to track the opening of cabinet doors.

Utilise Smart Technology

Employ smart tech to enable integration and communication across all of your security layers – from the perimeter fencing to server room checkpoints – to easily grant or deny access throughout your data centre facilities.

Security points to consider

  • Continually maintain and check your security systems
  • Service your gates not just for security but safety
  • Look for fencing products with a guarantee to ensure longevity and durability
  • Select products that blend in to the surrounding environment
  • Conduct risk assessments before and after installation
  • If noise control is a priority, select a fencing material that dampens sound (e.g. timber)
  • Secure the appropriate planning permissions before installation
  • Establish a plan for waste disposal of items such as used batteries
  • Hire experienced suppliers and installers to ensure that your security solution is complete
