What is SD-WAN?
SD-WAN (Software-Defined Wide Area Network) is a network technology controlled by software. In a specific enterprise, for example, enterprise A has two branches, A1 and A2, which provide services such as traffic encryption when communicating with the parent branch, distribution of network load according to demand, and setting up higher bandwidth for the line with higher demand. Located within the features of WAN. The main application of SD-WAN is to allow companies to build lower-cost and higher-performance WANs, which allows businesses to partially or completely replace more expensive private WAN communication technologies such as MPLS.
What are the questions to ask when choosing SD-WAN technology?
1. Risk of exposure. How will the risk profile of the enterprise change if SD-WAN technology is used?
IT professionals should keep this in mind when listening to sales offers about the unique security benefits of SD-WAN. One of the big misconceptions about SD-WAN today is that, thanks to encrypted traffic capabilities, SD-WAN is at the highest level of security by default during initial installation. While this encryption offers a layer of privacy and security protection, it requires additional scanning and filtering protection to detect / block malware, botnets, and other web threats that attack SD-WAN traffic.
2. Protection from threats. Does SD-WAN have any restrictions on the types of threats that can be detected?
It is important to use SD-WAN and other technologies together. For example, with Fortinet Fortigate (Firewall), you can provide in-depth analysis of traffic while setting up SD-WAN on one side. Here you can get help in technologies such as FortiGuard, FortiSandbox.
3. Compliance. Does the product support industry standards and all applicable regulatory requirements for data privacy obligations, including standards related to tracking, auditing and reporting functions?
For example, if the SD-WAN Cloud complies with the PCI-DSS 3.4 Compliance Certification (AoC) as a Level 1 Service Provider, this compliance requires the most rigorous evaluation and is considered the highest security standard.
4. Orchestration. Does it offer automated capabilities, including a wireless LTE / 5G global network, to identify applications and analyze paths to select the best network connections?
Here is an example of the "load balancing" feature used in SD-WAN technology. This feature can be adjusted according to various criteria, depending on the traffic IP-based, the degree of engagement of the line and the capacity of the line.
5. Management. Does the solution used provide easy installation and all-round control, especially over the cloud?
Here, basically, we can give an example of remote connection and management via VPN. Also, in a hybrid infrastructure, SD-WAN technology must be able to operate and be managed in an integrated way.
6. The total cost of the solution. Are there operating costs for implementing an SD-WAN and wireless WAN solution? If so, what does this include?
Here we can mainly include the licensing costs of the product and the additional costs required to ensure its safety.
7. Third Party Verification. Has the solution been thoroughly tested and recommended by independent experts?
Accreditation of solutions, meeting the required safety and industry standards is a key priority.
