Dedicated internet access vs. broadband: speed and security win the day

High-speed, low-latency connectivity is vital to enterprise business today. From connecting with your customers to conferencing to accessing your cloud applications, the speed and quality of your internet connection has an important impact on your ability to compete today—and grow tomorrow. So it’s not surprising that regional and global businesses are looking at dedicated internet access (DIA) and broadband and asking which best serves their data, security and customer experience needs.

Let’s take a look at two types of business internet services and compare their key features and benefits to help you decide which is right for your business.

Broadband vs. dedicated internet access

Internet service is far from a commodity. Choosing the right internet service is an increasingly important business decision. The two heavyweights in this arena are broadband and dedicated internet access. Let’s see how they stack up.

What is broadband?

Broadband is wide bandwidth data transmission, with many users sharing always-on, high-speed internet access via fiber, DSL, cable, satellite or other media. Bandwidth speeds are typically asymmetrical—meaning uploads and downloads have different speeds. Speed (reported as maximum) is determined by the amount of traffic among many users, and it varies from one time of day to the next.

What is dedicated internet access?

Dedicated internet access, by contrast, is an internet connection that goes directly to your business. It isn’t shared with neighboring buildings or users that can drain critical bandwidth. Providers dedicate a certain amount of bandwidth to a specific connection, usually through dedicated fiber, Ethernet or T-1 cable.

With DIA, you get a consistently high-performing symmetrical connection to public cloud applications, remote offices, data centers and more. The performance levels are typically backed by a service level agreement with your provider.

Compare the key capabilities of DIA and broadband to determine which one is best for your business:

• Upload/download speeds

  • DIA: Symmetrical speeds backed by a Service Level Agreement (SLA)
  • Broadband: Asymmetrical, speed determined by total traffic

• Internet bandwidth

  • DIA: Dedicated to your business
  • Broadband: Shared with your business and others in the network

• Delivery

  • DIA: Dedicated fiber
  • Broadband: Fiber, DSL, cable, satellite

• Support for IPv4 and IPv6

  • DIA: Yes
  • Broadband: No

• Security

  • DIA: Provides additional threat protection
  • Broadband: More vulnerable to intrusion

Which one is best for my business?

There are a number of reasonswhy businesses are looking to switch to DIA. Stable, always-on customer experiences and next-gen applications like artificial intelligence (AI) and machine learning (ML) depend on fast, reliable internet. Remote teams need symmetrical uploading and downloading for collaborating, file sharing and conferencing. Downtime is more costly than ever. And the need for more and more bandwidth continues to grow over time.

DIA is the way to go if your business demands:

• Stable, secure internet connections
• Fast, uniform upload and download speeds
• Exceptional customer experiences despite high-content demands
• High-end security protection against network attacks
• Top internet destinations and cloud-based applications for efficient management of business growth
• Efficient, reliable infrastructure to support market expansion, eCommerce applications and other rich website content
• Support for Pv4 and IPv4 / IPv6 dual stack

If DIA seems like the best way to keep your business running at full speed, look for a network provider that delivers these benefits, backed by the power of a reliable, secure global network. Of course, if your needs are simpler—or budget is an issue—broadband/fiber may be a viable alternative.
