How SD-WAN Technology is better than Traditional WAN?

Traditional WANs work over conventional routers. They are not cloud-friendly. They generally need backhauling all traffic—even that meant to the cloud—from multiple locations to a hub or main data center where security inspection is done. It often causes delays, hindering user experience and productivity as well.

SD-WAN technology, on the other hand, supports applications hosted in on-premises data centers, clouds and SaaS, Office 365, Dropbox.

How Does SD-WAN Technology Work?

This technology connects end users to virtually any application, regardless of location like public cloud or data center, using the best available transport service (e.g., MPLS, broadband, cellular and satellite internet link. This technology often uses a control function that continuously assesses traffic flows across the WAN and smartly direct traffic.

What are the Benefits of SD-WAN?

  • SD-WAN minimizes operating expenses by switching from expensive MPLS lines to broadband like cable, DSL, mobile broadband and fiber.
  • It lets you add new lines to the sites, thereby lowering the bottlenecks and delaying what is common in traditional WANs.
  • This technology is composed of multiple links from various ISPs, meaning other links would work if one fails.
  • SD-WAN lets you smartly assign key applications to various links, including internal lines as well as Internet connections. This way, you can assign the right resources in each scenario to increase performance and productivity while reducing costs.
  • Since IT is a digital tool, it is easy and quick to configure this technology to your current infrastructure. You don’t require sending the IT team to your site to configure it.
  • Last but not least—SD-WAN costs you nearly 1/3rd of the cost of using MPLS.

How Software Defined WAN Helps in Network Tracking?

SD-WAN technology lets you view what’s going on in the network, including online and registered appliances. It lets you monitor network events, site and tunnel status, report-based usages, availability of data on your overall network, application, servers, specific sites, and users.

Bottom Line:

SD-WAN is an intelligent and flexible network technology. It facilitates the network as well as minimizes downtime, bottlenecks, and expenditures. Given it is an advanced version of WAN, more organizations should opt for it to pace up with the digital transformation as well as the use of modern, cloud-based applications and technologies to empower their operations.

For example, unauthorized access can be tracked whenever it happens. The same thing goes for detecting malware within encrypted network traffic. You can create and analyze network logs and security devices.

  • Efficient Troubleshooting:

The proactive issue detection system can be planned with network intelligence. Instead of randomly detecting issues, a network admin can troubleshoot the issues with a more detailed and focused approach.

How Cloud and Mobile Pose Challenges to Network Visibility?

There is no doubt that visibility helps you consolidate your data security as you can detect certain issues. But things might get challenging if your network also includes cloud and mobile technology.

The modern WAN is composed of technologies like Internet VPNs, mobile and cloud services, making it difficult for the traditional network monitoring tool to provide visibility across the WAN. Even worse, an organization can be misguided by a false sense of security as they view all the traffic goes over the MPLS link.

Traditionally, network visibility is done by certain security and network monitoring tools such as firewalls, endpoint sensors, and security appliances. While these tools can work effectively when traffic moves within the WAN, they are likely to lose their efficiency when cloud and mobile enter the network.

Luckily, cloud-based SD-WAN can help in this scenario. Read the next point to find out how.

How Cloud-Based SD-WAN Can Help in Network Visibility?

Traditional tools are not effective when cloud and mobile come into play.

Enter cloud-based SD-WAN.

AI and Cybersecurity


The introduction of artificial intelligence (AI) into a wide range of situations is known to make such a situation better in terms of efficiency and experience. AI has gained recognition in many industries such as education, customer service, banking, and automation to mention a few. Recently, AI is beginning to gain popularity in cybersecurity and it is also playing a substantial role in the fight against cybercrime.

AI is valuable in cybersecurity because it advances how security experts investigate, study, and understand cybercrime. It boosts the cybersecurity know-hows that businesses use to fight hackers and help keep organizations and customers safe. Artificial Intelligence (AI) improves the efficiency of cybersecurity in the following ways:

  1. Timeliness: An AI-based cybersecurity is not founded on human monitoring alone. Threats can be detected almost immediately. In fact, there is no break once artificial intelligence is involved. Your network or system is always available 24/7 because it recognizes no holiday or non-work hours.

Also, this constant availability results in an immediate response to threats. That is, the security of your business is always around the clock.

 

  1. Speed: AI helps to filter the massive amount of data for an outlier in a short time. When this task is done by humans, it could take days or even a month before this can be achieved. In addition, manually creating a network security policy and understanding an organization’s network topography will most likely be cumbersome. For instance, a data center of average size may have up to 500 applications and could require 4,500 different security rules!

 

  1. Improves password protection and authentication: Passwords are a vital part of security. Nonetheless, we can be careless with our passwords or even use a single password for several accounts without changing it for an extended period of time. This approach makes your system or network easy to hack. Fortunately, AI enhances authentication and gets rid of imperfections thereby making your system more reliable.

 

  1. Vulnerability Management: Using AI as opposed to the traditional procedure in identifying risks is taking the innovativeness of your business a notch higher. This eliminates having to allow hackers to exploit the vulnerabilities of your network before you counteract them. AI helps you develop a proactive vulnerability management scheme.

Due to the increase in the complexity of networks, the ability to handle it is now beyond that of human beings alone. Therefore, using artificial intelligence will be a huge advantage to your business’s security and protection.

It is important to note that AI in cybersecurity can either be the savior or enemy of your business. It depends on whose arsenal the weapon (AI) belongs, either yours or your enemy’s (hacker). Therefore, be smart and take advantage of AI in securing your cyberspace instead of allowing the opposite site (hacker) to use it against you. CYNEXLINK is your go-to.

What is a Virtual Private Network (VPN) and Why it Matters


 

CyNexLink Blog   •   August 4, 2017

 

Remote and mobile work have become an integral part of most businesses with ever-advancing technological tools at our fingertips.

However with that expansion comes added security risks. The critical information of any employee could easily be compromised if they use unsecured remote connections. See Shadow IT. This is where a Virtual Private Network, or VPN, comes in handy.

A VPN is a private network of computers fused to establish a secure connection over a public network, or the Internet. It can protect data sent in messaging apps, emails and can safeguard online activity.

Wi-Fi security: It can help you connect to Wi-Fi outside of the office in generally unprotected areas like an airport or bookstore. The VPN will encrypt the activity of the user.

Anonymity: A VPN can keep communications secure from Internet service providers and allows users to use anonymous browsing due to the encryption.

Access to the web: Certain websites may not be accessible in certain countries. Organizations like Netflix or Hulu may block access to their web content based on geographical location. But a VPN can bypass these constraints.

Apart from security, a VPN can also allow businesses to glean a competitive advantage over others. As an example, a VPN allows you to connect to international servers, so businesses can monitor what their and their competitor’s advertisements look like in other markets. This can help businesses make better decisions on their marketing content.

When choosing a VPN, it’s best to look at several important features: price, speed, locations and privacy.

There are also different types of VPNs. Here are a few and the benefits and drawbacks of each:

IPSec VPN: Offers a remote access to the network through an application. These were developed for businesses that are spread out globally to connect on one central office network.

· Benefit: Creates a permanent connection between locations.

· Drawback: It can be difficult to restrict access because most corporate resources are available on the network.

SSL VPN: Built to benefit the remote worker, this VPN doesn’t have an application. This type is best for businesses that have teams that sometimes work remotely.

· Benefit: Easy to install because of the lack of an application.

· Drawback: Security might not be as good as an IPSec VPN.

Despite the positives of a VPN, there are still businesses that operate without them. If a company regularly has employees working remotely, then a VPN is a must. Moreover, the cost of a VPN is dwarfed in comparison to its necessity.

If customers even suspect that their information is at risk, they will generally take their business elsewhere. If companies want to avoid these standard, yet intricate security mistakes, then they need a strengthened security plan devised by a team of dedicated IT professionals.
