Wide-area networks (WAN) are a necessity when your business gets to a certain size, but Multiprotocol Label Switching (MPLS) can be expensive to implement across multiple locations and time-consuming to deploy and maintain. A Software-Defined Wide-Area Network (SD-WAN), on the other hand, can be set up quickly while cutting costs and improving application performance. If it fits your needs, an SD-WAN may be precisely the solution you’ve been waiting for. 

Here are six reasons why: 

1. More Efficient Bandwidth Usage

As more and more businesses rely on software-as-a-service (SaaS) solutions delivered by the cloud, SD-WAN’s ability to provide a secure and fast connection both within and without the network is becoming a game-changer. 

Instead of managing traffic by means of physical routers, an SD-WAN relies on a software overlay to provide more efficient WAN bandwidth utilization by means of dynamic path selection. Simply put, it prioritizes pathing for high-demand applications like video conferencing or Voice over Internet Protocol (VoIP). You’ll see noticeable performance improvements for these types of usages because your bandwidth is being allocated where it can make the biggest impact at any given time. 

2. SD-WAN Is Easy to Configure and Quick to Deploy

SD-WAN takes the network technology and infrastructure you already have and makes it work more efficiently. Making these kinds of network improvements to a traditional MPLS would require adding new hardware to your network, not to mention testing and configuring to make sure it works correctly before you could rely on it for business-critical operations. SD-WAN, however, is different. 

SD-WAN is deployed and controlled through a software platform rather than hardware, with a user-friendly interface that simplifies the process. Many SD-WAN solutions can even be implemented by non-technical staff, lightening the load on your IT department. 

This also means that you can get SD-WAN configured and ready to go at a new location in a matter of days, not weeks. For growing businesses, you get unrivaled flexibility and scalability while delivering a secure, fast connection when and when you need it. 

3. Customized Performance

A cloud-enabled SD-WAN can be easily configured with your organization’s specific needs in mind. For example, bandwidth can increase or decrease on-demand, giving you performance where you need it the most. 

You’re also likely to see improved speed and responsiveness with SD-WAN services. Traffic for high-demand applications gets routed through the fastest and most reliable connection, reducing common network issues like latency and jitter. Essentially, speed and reliability are delivered where it’ll make a difference in your day-to-day work. 

4. Better Security

The traditional approach to data security with an MPLS is to focus on a centralized, corporate data center that operates as the “vault” where you keep all of your data. However, with more and more companies relying on the cloud for business-critical operations, it’s your traffic that you need to protect, especially when you’re working across multiple locations. 

A key part of SD-WAN is end-to-end encryption throughout the network. This means that even if your traffic gets intercepted, your data is still protected. Your network is also segmented, containing any security breaches or damage and giving you the chance to respond quickly. 

User accounts can be another major threat vector for corporate networks. SD-WAN makes account creation, editing, and removal quick and straightforward. 

5. Better Voice Quality on a More Reliable Connection

In the past year, most of us have become familiar with the ins and outs of video and voice conferencing, including some of the common problems that come from this bandwidth-hungry mode of communication. If your VoIP calls are plagued with clipped words and stuttering connections, you may be experiencing packet loss. 

SD-WAN can solve this problem by implementing Forward Error Correction (FEC) to compensate for packet loss. Additionally, you can configure your network to route voice traffic along the most efficient path, making sure that your calls are clear and consistent. 

6. A Cost-Effective Solution

One of the biggest reasons to deploy an SD-WAN is how cost-effective it is. You get to reap the benefits of improved performance, reliability, and security simply by overlaying a software-side implementation onto the technology you already have. SD-WAN will use whatever connection makes the most sense for the user, whether that’s MPLS, Ethernet, WiFi, or anything else. 

When you need to grow, SD-WAN saves you money and time with simple deployment and configuration that can be achieved with minimal IT involvement. This networking technology keeps pace with your business while reducing overhead and equipment spending. 

SD-WAN helps you get the most out of the connectivity you already have, delivering bandwidth to the mission-critical applications that need it the most. 

What You Can Do Right Now 

For many growing businesses, a growing challenge is finding a networking solution that can keep pace with the increasing demands of bandwidth-hungry applications like voice and video while managing an ever-expanding list of cloud applications. You need something that will be secure no matter how you connect and where your traffic is headed. At the same time, you want something scalable that’s cheap and easy to implement. 

SD-WAN solves these problems with dynamic path selection, end-to-end encryption, and a user-friendly configuration interface, all while overlaying onto the network infrastructure you already have. SD-WAN will help you get the most out of your internet connection by delivering performance to applications where it matters the most. Here’s why your business needs SD-WAN: 

• Use the bandwidth you already have more efficiently with dynamic path selection. 
• Set up and configure new locations quickly and easily, without spending on more equipment. 
• Customize your network performance to prioritize the applications where performance matters the most. 

• Protect your data with end-to-end encryption. 
• Improve your VoIP experience with minimized packet loss and better performance. 
• Get more for your money and maximize the value you get from your internet connection. 

1. Types of Threats and Vulnerabilities in Cyber Security 

As the recent epidemic of data breaches illustrates, no system is immune to attacks. Any company that manages transmits, stores, or handles data must institute and enforce mechanisms to monitor their cyber environment, identify vulnerabilities, and close up security holes as quickly as possible. 

Before identifying specific dangers to modern data systems, it is crucial to understand the distinction between cyber threats and vulnerabilities. 

Cyber threats are security incidents or circumstances that can have a negative outcome for your network or other data management systems. 

Examples of common types of security threats include phishing attacks that result in installing malware that infects your data, failure of a staff member to follow data protection protocols that cause a data breach, or even nature’s forces that takes down your company’s data headquarters, disrupting access. 

Vulnerabilities are the gaps or weaknesses in a system that make threats possible and tempt threat actors to exploit them. 

Types of vulnerabilities in network security include but are not limited to SQL injections, server misconfigurations, cross-site scripting, and transmitting sensitive data in a non-encrypted plain text format. 

When threat probability is multiplied by the potential loss that may result, cybersecurity experts refer to this as a risk. 

TYPES OF CYBERSECURITY THREATS 

Just as some germs and diseases can attack the human body, numerous threats can affect hardware, software, and the information you store. Some of the major ones include the following: 

Viruses are designed so that they can be easily transmitted from one computer or system to another. Often sent as email attachments, viruses corrupt and co-opt data, interfere with your security settings, generate spam, and may even delete content. 

Computer worms are similar; they spread from one computer to the next by sending themselves to all of the user’s contacts and subsequently to all contacts’ contacts. 

Trojans. These malicious pieces of software insert themselves into a legitimate program. Often, people voluntarily let trojans into their systems in email messages from a person or an advertiser they trust. As soon as the accompanying attachment is open, your system becomes vulnerable to the malware within. 

Bogus security software that tricks users into believing that their system has been infected with a virus. The accompanying security software that the threat actor provides to fix the problem causes it. 

The adware tracks your browsing habits and causes particular advertisements to pop up. Although this is common and often something you may even agree to, adware is sometimes imposed upon you without your consent. 

Spyware is an intrusion that may steal sensitive data such as passwords and credit card numbers from your internal systems. 

A denial of service (DOS) attack occurs when hackers deluge a website with traffic, making it impossible to access its content. A distributed denial of service (DDOS) attack is more forceful and aggressive since it is initiated from several servers simultaneously. As a result, a DDOS attack is harder to mount defenses against it. 

Phishing attacks are social engineering infiltrations whose goal is to obtain sensitive data: passwords and credit card numbers incorrectly. Via emails or links coming from trusted companies and financial institutions, the hacker causes malware to be downloaded and installed. 

SQL injections are network threats that involve using malicious code to infiltrate cyber vulnerabilities in data systems. As a result, data can be stolen, changed, or destroyed. 

Man-in-the-middle attacks involve a third party intercepting and exploiting communications between two entities that should remain private. Eavesdropping occurs, but information can be changed or misrepresented by the intruder, causing inaccuracy and even security breaches. 

Rootkit tools gain remote access to systems without permission and can lead to the installation of malware and the stealing of passwords and other data. 

COMMON NETWORK VULNERABILITIES 

Even seemingly minor flaws or oversights in the design or implementation of your network systems can lead to disaster. 

Some of the most common network vulnerabilities include the following gaps in your application security: when applications are not kept up-to-date, tested, and patched, the doors are open to code injection, cross-site scripting, insecure direct object references, and much more.
