What is a WAN? For expanding businesses, overcoming connectivity challenges is crucial. Secure and reliable data sharing across distant locations is pivotal for the success of any growing enterprise. To ensure teams stay interconnected and maintain productivity, business owners should focus on establishing a robust network.
A Wide Area Network (WAN) is a dependable solution to enhance your company’s connectivity, supporting seamless communication and data exchange between widespread offices.
What is a WAN?
Simply put, a WAN is an IP-based network that connects two or more business locations. It’s generally designed to support everything your various teams might need to share — like internal communications, computer systems and your intranet.
There are two types of WANs: Peer-to-Peer (P2P) networks and Virtual Private Networks.
P2P networks are designed to link local sites within a radius of 45 km of one another — so this type of Wide Area Network is useful for businesses with multiple branches within the same general area. P2P networks are able to link various business locations by creating a WAN path that goes from one location and through a network provider to another remote site. P2P networks are also sometimes called “leased lines”.
The biggest benefit of using a P2P network is that you don’t have to share bandwidth with other companies, and so these networks are generally faster than ordinary broadband connections.
The other type of WAN is a VPN. This type of network is essential if your offices or branches are sprinkled throughout the country, but you want each location to have access to the same IT systems and sensitive data.
VPNs work sort of like ordinary Internet connections that are encrypted. That means all the data you send on your network is completely private, and only people and locations that are invited to connect to your private network can have access to it.
Why is a WAN Important for My Business?
Now that you know the answer to what a WAN is, why would you want to use one at your small business?
If you want to share sensitive data between multiple business locations, it makes perfect sense to invest in a Wide Area Network. There simply isn’t a more reliable or more secure way to keep your business connected. But there are quite a few other benefits that come hand-in-hand with developing a P2P network or VPN, too.
First and foremost, a WAN enables you to totally centralize your company’s IT infrastructure. If you’ve got a P2P network or VPN, you don’t need to buy a separate file server or email server for each business location — which will not only keep things simple, but also keep things cheap. WANs can also carry phone calls so that you don’t have to rent ISDN circuits, either.
Companies that use WANs also generally get things done quicker. VPNs and P2P networks are made up of leased lines rather than broadband connections — which means WANs offer much faster upload speeds. Commands are effectively made in real-time, and most corporate WANs come with unlimited data transfer.
At the end of the day, very few growing companies have got anything to lose by investing in a WAN. If your business is growing rapidly, you have multiple branches or offices and you’ve got to share secure data between those offices in order to keep things running smoothly, the benefits of P2P networks or VPNs are staggering.
Just remember to do your homework. Every Wide Area Network service is a little bit different, and each provider comes with its own unique setup. That means you should sit down, take stock of your company’s needs and do your homework before jumping into any sort of service agreement.
Ensuring a Smooth WAN Implementation
Implementing a Wide Area Network (WAN) is a strategic move for businesses, but it’s essential to ensure a smooth transition and operation. Here are key considerations:
Assess Network Needs
Before diving into the selection of a WAN solution, a comprehensive assessment of your network needs is essential. This involves understanding the volume of data traffic, types of applications used, the geographical location of offices, and future growth plans.
Analyzing these factors will provide a clear picture of what you require from a WAN solution, whether it’s high bandwidth, low latency, reliability, or security. This step is crucial in ensuring that the chosen WAN solution aligns perfectly with your business objectives and operational demands.
Select the Right WAN Type
Choosing the appropriate Wide Area Network type is a pivotal decision that depends on the specific needs of your business. For companies with geographically dispersed branches, a Virtual Private Network (VPN) might offer the flexibility and security needed for remote access.
Conversely, businesses with locations within closer proximity may benefit from the high-speed and reliability of a Peer-to-Peer (P2P) network. Consider factors such as data sensitivity, required speed, and the physical distance between locations to determine the best WAN solution for your business.
Evaluate Providers
Selecting the right service provider is crucial for the successful implementation and operation of your WAN. Look for providers with a robust network infrastructure, reliable customer service, and competitive pricing.
Assess their service level agreements (SLAs) to ensure they meet your business’s uptime and support requirements. Additionally, consider providers that offer added value through complementary services such as cloud connectivity, managed security, and network monitoring.
Plan for Scalability
As your business grows, so will your network needs. It’s important to choose a WAN solution that can scale with your business without requiring a complete overhaul of the existing infrastructure.
Discuss scalability options with potential providers, including the ability to add bandwidth, connect new sites, and integrate advanced technologies. Planning for scalability from the outset will save time and resources in the long run and support your business’s expansion efforts.
Prioritize Security
The security of your WAN is paramount, especially when transmitting sensitive data across multiple locations. Ensure that the WAN solution you choose offers robust security features, including end-to-end encryption, firewall services, and intrusion detection systems.
Consider implementing additional security measures, such as multi-factor authentication and secure access protocols, to further protect your network against potential threats.
Train Your Team
The successful deployment and ongoing management of your Wide Area Network require a knowledgeable and skilled team. Invest in training for your IT staff to ensure they are equipped with the necessary skills to configure, manage, and troubleshoot the system.
Additionally, educate end-users on best practices for secure network usage to minimize risks and enhance overall network performance.
Monitor and Maintain
Continuous monitoring of your WAN is essential to ensure optimal performance and quickly identify any issues. Implement network monitoring tools that provide real-time insights into traffic patterns, bandwidth utilization, and potential security threats.
Regular maintenance, including software updates and hardware inspections, will help prolong the life of your WAN infrastructure and maintain its efficiency.
Backup and Redundancy
To ensure network reliability and minimize downtime, implement backup and redundancy strategies for your WAN. This might include secondary connections, failover systems, and redundant hardware.
These measures provide a safety net in case of network failures, ensuring that your business operations can continue uninterrupted.
Compliance and Regulations
Stay informed about relevant compliance standards and regulations that affect your WAN, especially if you operate in industries subject to strict data protection and privacy laws. Ensure that your WAN solution and practices adhere to these regulations to avoid legal penalties and protect customer data.
Regularly review compliance requirements and adjust your network security policies accordingly.
Disaster Recovery
Develop a comprehensive disaster recovery plan that includes provisions for your WAN. This plan should outline steps to restore network connectivity in the event of natural disasters, cyberattacks, or other catastrophic events.
Regular testing of the disaster recovery plan will ensure that your business is prepared to quickly respond and recover from disruptions.
Regular Audits
Conducting regular audits of your WAN infrastructure and policies is crucial for identifying potential improvements and ensuring compliance with industry standards.
These audits can help uncover vulnerabilities, assess the effectiveness of security measures, and evaluate the overall performance of the network. Insights gained from regular audits can guide strategic decisions and enhancements to your WAN solution.
By following these strategic steps, businesses can effectively implement a WAN solution that meets their connectivity needs, supports growth, and ensures the security and reliability of their network infrastructure.
