Data is one of the most valuable assets a modern business owns. Customer records, financial information, applications, communications, intellectual property, operational systems, and backups all depend on infrastructure that needs to be available and protected around the clock.
That makes choosing where your servers, systems, and business-critical information are hosted a much bigger decision than simply comparing storage space or bandwidth.
Modern ICT data centre need to defend against several different types of risk at once. Cyberattacks may get most of the headlines, but physical intrusion, power failure, overheating, fire, flooding, hardware failure, and connectivity interruptions can be just as disruptive.
For South African businesses, resilience is particularly important. Companies increasingly rely on cloud applications, online communications, remote access, real-time systems, and always-on connectivity. When infrastructure goes down, employees can lose access to the tools they need, customer service can grind to a halt, and revenue-generating activities may be interrupted.
ICTGlobe believes effective data centre security should therefore be layered. Protecting servers behind a locked door simply isn’t enough. Physical security, environmental protection, power resilience, network security, backups, monitoring, and disaster recovery all need to work together.
Here are the security features we believe every business should look for when evaluating ICT data centre.
1. Controlled Physical Access
One of the most fundamental data centre security principles is also one of the simplest: only authorised people should be able to reach the infrastructure.
Servers may contain enormous quantities of valuable business information, which means unrestricted physical access creates an unnecessary risk.
Secure ICT data centre should implement strict access-control procedures governing who may enter sensitive areas, when they may enter, and how that access is recorded.
At our tier 3-rated data centre in Highveld, Centurion, physical security incorporates several layers of protection.
These include:
- Strict access-control policies
- Biometric access control to the building and data centre areas
- Tamper alarms on biometric readers
- Locked security gates that operate separately from electronic access control
- Controlled access to sensitive infrastructure areas
Biometric authentication provides an important additional layer because access is linked to authorised individuals rather than simply relying on keys or access cards that could potentially be lost, copied, or shared.
Layered physical access controls create hurdles between the outside world and business-critical equipment.
2. Round-the-Clock Physical Security
Technology should complement human oversight rather than replacing it completely.
A professional ICT data centre should have physical security measures capable of identifying suspicious activity, unusual access, or potential problems at any time of the day or night.
Our facility operates under 24-hour security, with additional hourly patrols after hours.
This provides an important human layer alongside electronic security controls.
After all, servers don’t stop being important when everyone else goes home.
For organisations whose digital infrastructure operates 24/7, the building protecting that infrastructure should be watched 24/7 too.
3. CCTV Surveillance and Retained Security Records
Surveillance is another critical component of physical data centre security.
CCTV systems can discourage unauthorised behaviour while providing valuable records if an incident needs to be investigated.
However, simply installing cameras isn’t enough. A robust security environment should also consider how long surveillance information and access records are retained.
Our CCTV footage is subject to a one-year recording retention policy. In addition, our access-control logs also have a one-year retention policy.
Together, these controls help create an auditable trail of physical activity around sensitive infrastructure.
For businesses dealing with valuable, confidential, or regulated information, being able to determine who accessed an environment and when can become particularly important.
4. Redundant Power Infrastructure
Data centre security isn’t only about preventing deliberate attacks. Protecting availability is just as important as protecting confidentiality.
A perfectly secure server isn’t much use to a business if nobody can access it because the data centre has lost power.
That’s why power resilience should be one of the first questions businesses ask when comparing ICT data centres.
Our data centre uses redundant power utility infrastructure supported by double backup generators. Primary and secondary power feeds use automated switchover UPS equipment with dedicated battery banks.
This infrastructure supports our 99.999% uptime guarantee.
Redundancy matters because it removes dependence on a single component. If one part of the power chain experiences a problem, another can take over.
For South African businesses, where electricity resilience has become an important part of long-term technology planning, this isn’t merely convenient. It’s an important part of business continuity.
5. Intelligent Cooling and Temperature Management
Servers generate heat. Lots of it.
Without effective cooling, rising temperatures can affect equipment performance and potentially contribute to hardware failure.
Temperature control should therefore form part of any serious data centre risk-management strategy.
Our facility uses water-cooled, temperature-controlled equipment designed to operate efficiently in South African climatic conditions. Fully redundant hot-air containment further supports the cooling environment.
Individual cabinets are also monitored for temperature changes, with the information integrated into our monitoring infrastructure.
This provides another important layer of protection: detecting changing environmental conditions before they become bigger problems.
A secure data centre doesn’t just guard servers from people. It protects them from their surroundings too.
6. Early Fire Detection
Fire represents one of the most serious physical threats to technology infrastructure.
The best approach isn’t simply having equipment available to extinguish a fire. A well-designed data centre should detect potential signs as early as possible.
ICTGlobe uses a two-stage fire detection system.
Its early-warning monitoring can detect changes in airborne particles or smoke and alert monitoring staff to potential environmental changes. A secondary detection stage can then trigger the facility’s gas-based fire-suppression system when predefined thresholds are reached.
The aim is straightforward: detect developing conditions quickly and respond before they can cause extensive damage.
7. Fire Suppression Designed for Technology Environments
Putting out a fire in an ordinary office and putting out a fire around sensitive electronic infrastructure are very different challenges.
Traditional water-based firefighting methods can introduce another serious risk to servers and networking equipment.
Our automatic fire-suppression system is linked to the fire alarm and uses HFC-227ea gas, which leaves no residue on equipment following discharge.
Smoke and particle detectors are positioned throughout key infrastructure areas, including the Data centre, communications room, UPS room, and beneath the raised flooring.
It is an important reminder that effective data centre protection requires systems designed specifically around technology infrastructure rather than generic building-security measures.
8. Water Leak Detection and Flood Prevention
Fire may be the more dramatic threat, but water can be equally disastrous for electronic equipment.
Leaks may originate from cooling infrastructure, plumbing, weather conditions, or other building systems. Left undetected, even a relatively small leak can become a major problem.
Secure ICT data centres should therefore incorporate environmental monitoring beyond temperature alone.
Our environment includes automated notifications from water-leak sensors, alongside flooding-prevention measures using automated water pumps.
Humidity and temperature sensors also generate automated notifications.
By continuously keeping watch over environmental conditions, problems can be identified far sooner than they might be through manual inspections alone.
9. Network Security and Advanced Firewalls
Once the building itself has been secured, attention needs to turn to the digital perimeter.
Servers connected to business networks and the internet need protection against unauthorised access, malware, intrusion attempts, and other cyber threats.
Firewalls remain a crucial part of this defence, but modern security goes considerably further than simply blocking a few ports.
As part of our broader managed ICT offering, ICTGlobe provides Firewall as a Service powered by Fortinet FortiGate firewalls.
The service includes capabilities such as:
- Centralised, cloud-based firewall management
- Intrusion detection and prevention
- Real-time threat intelligence
- Threat filtering
- Scalable protection for multi-branch organisations
- Compliance-ready configurations
The benefit of managed firewall services is that security doesn’t become a piece of equipment that is installed and then forgotten. It becomes an actively managed part of the wider ICT environment.
10. Continuous Monitoring and Threat Detection
Cybersecurity is constantly changing.
New vulnerabilities emerge, attackers alter their methods, software environments evolve, and businesses add new systems and users. Security controls therefore need ongoing management.
Our managed services take a proactive approach, with real-time monitoring used to identify potential issues before they develop into major disruptions.
Cybersecurity measures can include multi-layered protection, firewall management, system monitoring, and routine audits.
This type of visibility is especially valuable because many problems don’t announce themselves loudly.
Unusual network traffic, configuration changes, performance degradation, repeated access attempts, and suspicious activity may initially appear relatively minor. Continuous monitoring gives technical teams an opportunity to spot patterns and respond sooner.
11. Secure Backups
Even the strongest preventative security can’t guarantee that nothing will ever go wrong.
Hardware can fail. Files can be deleted accidentally. Systems can become corrupted. Cyberattacks can compromise data. Human error happens.
That is why backup needs to sit alongside prevention as a central part of any data-protection strategy.
ICTGlobe’s StorVault provides secure online backup and recovery options for business data, with automatic backup capabilities and advanced encryption protocols.
Our solutions can protect business-critical information as well as Microsoft 365 data, helping organisations recover information that may otherwise be lost following accidental deletion, ransomware, or other incidents.
Crucially, backups need to be recoverable.
Having a backup somewhere isn’t the end goal. Being able to restore the information when operations depend on it is what matters.
12. Business Continuity and Disaster Recovery Planning
Backup and disaster recovery are closely related, but they aren’t the same thing.
A backup gives you another copy of your data.
A disaster recovery strategy addresses the bigger question: How does the business get its critical systems working again?
The answer may involve infrastructure, applications, connectivity, staff responsibilities, recovery priorities, and alternate environments.
Our data centre offering includes business continuity planning and implementation as well as disaster recovery road mapping.
This allows businesses to think beyond individual servers and consider what would happen to the organisation as a whole if an unexpected event disrupted normal operations.
Strong ICT infrastructure isn’t simply designed to avoid failure. It should also help organisations recover effectively when disruption occurs.
13. Colocation with Enterprise-Grade Protection
Not every organisation wants to move everything into a public cloud environment.
Some businesses want to continue owning and controlling their physical servers while moving those servers out of an office environment.
That’s where colocation becomes valuable.
ICTGlobe offers secure colocation hosting and meet-me-room services from our Centurion data centre.
Instead of keeping expensive server infrastructure in an office building that may not have specialist power, cooling, fire suppression, access control, or monitoring systems, businesses can place their equipment within purpose-built data centre infrastructure.
They retain control of their hardware while benefiting from the surrounding resilience of a professional facility.
Our broader data centre solutions also include:
- Virtual server hosting
- Layer 2 services
- Consolidation and optimisation
- Transformation and automated systems management
- Cloud-based Infrastructure as a Service
- Business continuity planning
- Disaster recovery road mapping
This flexibility allows businesses to create infrastructure around their actual operational needs rather than trying to squeeze every organisation into the same hosting model.
Why Layered Security Matters for ICT Data Centres
There’s no single security technology that can protect a data centre by itself.
- A biometric reader won’t stop a server from overheating.
- A firewall won’t help during an extended power interruption.
- A backup won’t prevent unauthorised entry to a server room.
- A generator won’t detect ransomware.
Each control deals with a different category of risk.
That’s why the strongest ICT data centres use overlapping layers of protection that combine:
- Physical access security
- Security personnel
- CCTV surveillance
- Access logging
- Power redundancy
- UPS and generator backup
- Intelligent cooling
- Temperature and humidity monitoring
- Fire detection and suppression
- Water-leak detection
- Flood mitigation
- Network firewalls
- Intrusion detection and prevention
- Threat monitoring
- Encrypted backups
- Disaster recovery
- Business continuity planning
If one layer is challenged, other layers remain in place.
That resilience is ultimately what businesses are buying when they choose professional data centre infrastructure.
What South African Businesses Should Ask Before Choosing a Data Centre
When evaluating a potential provider, don’t base your decision on price alone.
Ask practical questions about what happens when something goes wrong.
For example:
- Who can physically access the servers? Look for controlled, auditable access rather than an ordinary locked server room.
- What happens during a power failure? Ask about UPS infrastructure, generators, redundancy, and automatic switchover.
- How is the environment monitored? Temperature, humidity, smoke, particles, and water leaks all matter.
- How is fire handled? A data centre should use detection and suppression technology suitable for electronic equipment.
- How is network traffic protected? Firewalls, intrusion prevention, monitoring, and threat filtering should form part of the discussion.
- How are backups handled? Find out how data is protected, where it is stored, and how recovery works.
- What happens after a major disruption? Business continuity and disaster recovery planning should not begin after disaster strikes.
- Is technical support available when your business needs it? Technology problems rarely respect office hours, particularly when systems support customers or operations around the clock.
These questions help turn a technical buying decision into a business-risk decision, which is exactly what data centre selection should be.

FAQs About ICT Data Centres
What is an ICT data centre?
An ICT data centre is a specialised facility used to house servers, networking equipment, storage systems, and related technology infrastructure. Professional data centres provide supporting systems such as secure access, reliable power, cooling, connectivity, environmental monitoring, fire protection, and cybersecurity measures.
What security should ICT data centres have?
Secure ICT data centres should combine physical and digital safeguards. These typically include controlled access, CCTV, security monitoring, redundant power, environmental monitoring, fire detection and suppression, network security, intrusion prevention, backup systems, and disaster recovery planning.
Why is biometric access important in a data centre?
Biometric access helps restrict sensitive areas to authorised individuals. Because authentication is tied directly to an authorised person, it provides an additional layer beyond ordinary keys or access cards.
Why is redundant power important for a South African data centre?
Businesses increasingly depend on continuously available digital systems. Redundant utility feeds, UPS systems, battery banks, and generators reduce the risk of a single power failure taking critical infrastructure offline.
What is data centre colocation?
Colocation allows a business to place its own servers or other hardware inside a professional data centre. The organisation retains control over its equipment while benefiting from purpose-built power, cooling, physical security, monitoring, and connectivity infrastructure.
Does ICTGlobe offer colocation?
