Network infrastructure for global enterprises: challenges and solutions

The globalisation of business presents many challenges for organisations with offices in different parts of the world. In particular, there is a growing need for a reliable network infrastructure that can provide uninterrupted access to corporate resources, high data transfer speeds and protection against cyber threats. An efficient network is the foundation for the smooth operation of international businesses, so it is essential to address performance, security and network management issues.

Let's explore the key network security challenges and solutions that can help global organisations optimise their network strategies, increase network efficiency and security, and ensure uninterrupted data exchange between remote offices.

Challenges of building a network infrastructure for global enterprises

Enterprises operating in a global environment face many challenges when building a network infrastructure. These include scalability, remote management, data latency and security.

The impact of geographic distance on network performance

Geographic distance always affects the performance of corporate networks. Data transmission over long distances is often subject to delays and slower speeds. This can be a serious obstacle for companies with offices in different parts of the world. For example, it can take several seconds to synchronise data between data centres in the US and Asia, which can significantly impact the operation of critical real-time applications.

Delays are particularly critical for organisations that use video conferencing, cloud services or analytics platforms. To solve this problem, you need optimised business networking solutions, such as SD-WAN, that allow you to route traffic more efficiently.

SD-WAN (Software-Defined Wide Area Network) is a software-defined enterprise-wide area network that allows businesses to manage distributed networks more efficiently using software rather than traditional routers and hardware.

The idea behind SD-WAN is to provide intelligent traffic management between branch offices, data centres and cloud services. This allows you to optimise data routing by choosing the best routes for information transmission based on current load, available resources and traffic importance.

Security challenges

International organisations also face an increased risk of cyber-attacks due to the greater number of network access points. Every remote branch or office connected to the global network represents a potential vulnerability that can be exploited by attackers. Vulnerabilities in remote offices, which often have weaker security systems, can become a gateway for hackers to enter the network and spread malicious attacks to other parts of the infrastructure. Such attacks can lead to network outages, confidential data leaks and significant financial losses.

In such circumstances, the enterprise network infrastructure requires the implementation of comprehensive cybersecurity solutions that can reliably protect data and applications, even with a scalable infrastructure. This includes the integration of advanced tools such as encryption, multifactor authentication, firewalls, VPNs and intrusion detection and prevention systems (IDS/IPS). It is also important to deploy centralised security monitoring systems that enable IT departments to monitor the network in real time and respond quickly to any anomalies.

Strategies for building a reliable network infrastructure

To build a robust network infrastructure, global enterprises need to implement innovative solutions that deliver flexibility, performance and security. Key design principles include the use of the latest WAN, LAN and SAN technologies, as well as data backup and protection methods.

WAN, LAN and SAN solutions

• WAN (Wide Area Network) solutions allow businesses to connect branches in different geographical regions into a single network. In particular, SD-WAN technologies allow for optimised traffic routing and stable connectivity even outside of the main communication channels.
• LAN solutions (Local Area Network) provide fast and stable connectivity within individual offices or data centres, allowing for efficient use of internal resources.
• SAN solutions (Storage Area Network) - networks for storing information that provide access to large-scale data arrays distributed between different physical and cloud storage facilities.

Manage network branches and ensure uninterrupted connectivity

Effective network management on a global scale requires the use of monitoring and remote management tools. Modern network solutions enable organisations to monitor the health of their networks in real time, automatically detect faults and resolve them quickly.

Tools for monitoring and managing networks

Network monitoring and management tools, such as Cisco Catalyst™ Centre or SolarWinds, provide IT professionals with powerful capabilities to keep their network infrastructure running at peak performance. They enable real-time monitoring of network health, traffic analysis, identification of bottlenecks and problem areas, and automated management of network operations. These tools can warn of potential problems before they occur, helping to prevent emergencies and minimise downtime.

With built-in automation features such as traffic balancing and security policy configuration, these platforms simplify the management of complex WANs. They also provide in-depth analysis of network events, helping IT departments quickly diagnose problems and take the necessary action to resolve them. In this way, monitoring tools can significantly improve network reliability, reduce the risk of data loss and downtime, and ensure uninterrupted connectivity between different company locations.

Reliability and data redundancy

To ensure uninterrupted network operations, it is important to use redundant communication channels and data protection technologies. Solutions such as cloud backup and data replication can help you avoid data loss, even in the event of a hardware failure or cyber-attack. Commvault Backup and Recovery, for example, provides reliable data protection and rapid recovery in the event of a disaster. With this solution, organisations can automatically backup and replicate data to the cloud or local servers, ensuring that critical information is quickly available even after a major network outage.

By using SAN and NAS storage devices, organisations can provide an additional level of reliability and availability, allowing them to store large amounts of information with the ability to recover it quickly. This approach not only provides business continuity but also protects against potential data loss in any environment.

Securing global network infrastructure

Global network security is one of the most important issues for international businesses. The proliferation of branches and remote offices increases the risk of cyber-attacks, so companies need to implement comprehensive solutions to protect their data and applications.

Use of firewalls and VPNs

Firewalls and virtual private networks (VPNs) are important elements in protecting corporate networks from external threats by creating a layered security system. Firewalls play a leading role in traffic filtering, blocking potentially harmful or unauthorised requests to the network. They can be configured to dynamically respond to new threats, detect suspicious activity and prevent intruders from entering the corporate infrastructure. Modern firewalls, such as next-generation firewalls (NGFWs), can analyse traffic not only at the IP address level but also by application, increasing their effectiveness.

Virtual Private Networks (VPNs) allow employees and partners to securely connect to corporate resources from anywhere in the world, ensuring the confidentiality of information transmitted over secure communication channels. Implementing a VPN is particularly important for global organisations, as employees often work in remote offices or connect from different regions. Using a VPN encrypts all traffic between the user's device and the corporate network, reducing the risk of data being intercepted in transit.

Together, firewalls and VPNs provide comprehensive protection for corporate networks, combining the blocking of external threats with secure access to resources, regardless of user location. This helps reduce the risk of cyber threats and provides a reliable level of security for the company's IT infrastructure.

Integrating artificial intelligence for network security

Modern Artificial Intelligence (AI) solutions are revolutionising cybersecurity approaches by enabling automated, real-time threat detection and response. AI systems use machine learning techniques to analyse vast amounts of data from an organisation's network to identify potential threats. With the ability to analyse user behaviour patterns and network anomalies, AI can not only detect known attacks but also predict new types of threats based on behavioural anomalies.

For example, AI can automatically identify suspicious activity, such as an atypical number of server requests or unusual changes in data access, and immediately alert you to a potential attack. This provides a much faster response than traditional security systems, which often require manual intervention. In addition, AI solutions can make decisions on their own, such as blocking suspicious traffic or isolating infected systems, minimising potential loss before the threat becomes serious.

Platforms such as Cisco SecureX use AI to create comprehensive maps of network activity, helping security analysts not only detect attacks quickly but also gain deeper insights into the nature and vector of the threat. Combined with other cyber defence tools, AI is helping to increase the effectiveness of global organisations' defences, significantly reducing the time it takes to detect and neutralise threats.

By using AI to ensure network security, organisations can not only defend against today's cyber threats but also stay ahead of them by preventing and responding to attacks in real-time.
