ISP Products

Dedicated Internet (DIA)

Lumen operates as a direct provider, offering its Dedicated Internet Access over its own 340,000-mile fiber network. This gives them direct control over a wide range of speeds, from 10 Mbps up to 100 Gbps, all backed by a 99.99% uptime SLA.

Our data shows Lumen's DIA installation time is 68 days, which is faster than the 77-day market average. Pricing is also competitive, tracking slightly below average for 1 Gbps circuits.

Granite takes a different approach as an aggregator with its Granite AccessExpress service. Instead of owning the "last mile" fiber, they source DIA from a variety of underlying carriers, which means available speeds depend on the location.

While Granite provides a 99.99% on-net DIA SLA, off-net service levels are determined by the partner carrier. According to our data, Granite's installation times are closer to the market average at 72 days, with pricing that trends about 21% higher for 1 Gbps circuits.

The choice often comes down to whether you prefer a direct network owner or an aggregator that manages multiple carrier relationships. Both providers offer valuable add-ons; Lumen provides services like DDoS mitigation and Cloud Connect, while Granite offers managed solutions including SASE/SD-WAN and wireless backup.

Keep in mind that the pricing and installation figures we've discussed are market-wide averages. Your actual costs and timelines can vary based on factors like geographic location and the specific circuit configuration you need.

To get an exact comparison for your locations, we recommend filling out our questionnaire. It uses the industry's most comprehensive data set to generate real-time quotes from Lumen, Granite, and other top ISPs.

DIA Pricing, Delivery and Install Days Compared

The data in this table comes from Lightyear’s aggregated ISP quotes collected in 2024 and 2025 YTD.

• Install Days: how long it typically takes to deliver service.
• 100Mb Price vs Avg / 1Gb Price vs Avg: shows whether this ISP is cheaper or more expensive than the market average.
• Delivery Point: “Suite” means the ISP delivers service all the way to the company’s server room; “MPOE” means the circuit stops at the building’s minimum point of entry (typically the building's utility basement) and the tenant must handle the inside wiring.

Wireless

Lumen’s wireless offering, the Enterprise Wireless Access Service (EWAS), provides 4G LTE and 5G connectivity by using the networks of T-Mobile, Verizon, and AT&T. This service is available across the United States for primary or backup access, but you'll need to contact a sales representative for pricing information.

Granite also provides multi-carrier wireless services, offering managed mobility, fixed wireless access, and multi-carrier SIMs across the US and Canada. This gives them a slightly broader range of wireless solutions compared to Lumen's single EWAS product.

For both providers, service level agreements are not publicly available and depend on the underlying carrier. The main difference is Granite's wider service area, which includes Canada, and its more varied portfolio of managed wireless options.

Security

Lumen provides a broad portfolio of standalone and managed security products through its Lumen Cybersecurity Solutions. These offerings include foundational tools like DDoS Mitigation and Managed Firewalls, as well as advanced services such as a Web Application Firewall (WAF) and a Virtual Security Operations Center (SOC). Many of these are powered by threat intelligence from their in-house group, Black Lotus Labs®.

Granite’s approach integrates security directly into its managed network services, with a focus on Secure Access Service Edge (SASE) and SD-WAN. Instead of a wide menu of individual products, Granite provides security policy orchestration as a core component of its managed platforms. This model is designed for businesses looking for a single, unified solution for both networking and security.

Broadband

Granite offers a managed broadband aggregation service, Granite Access, across the US and Canada. As an aggregator, they source service from various underlying carriers, with speeds up to 5 Gbps depending on the location. Our data shows Granite's broadband installation time is 41 days, which is longer than the 28-day market average, and their pricing trends about 29% higher than average.

Lumen also provides business broadband services. Due to limited quoting history in our dataset, we’re not able to provide benchmark pricing or installation timelines at this time. Since broadband options are highly location-dependent, the best way to get a direct comparison is to fill out our questionnaire for real-time quotes from both providers.

Ethernet

A direct comparison of Ethernet services isn't possible, as Lumen Technologies has discontinued its offerings in this category.

Granite, however, provides both Dedicated and Carrier Ethernet by aggregating services from various underlying carriers across the US and Canada. They manage the entire lifecycle of the service, with ordering and visibility handled through their Granite360 and AccessExpress platforms.

POTS Replacement

Lumen’s Cloud Communications Specialty Lines is a fully managed service designed to replace traditional POTS lines for critical systems like fire alarms and elevators. The solution includes all necessary equipment and installation, and it can operate over any existing internet connection, supported by multi-carrier cellular backup for constant uptime.

Granite offers a similar solution with its EPIK POTS replacement service, which is also compliant with NFPA 72 safety standards. It supports both wired internet and LTE backhaul, which can be used for primary connectivity or failover. While it includes battery backup, the exact runtime varies by configuration, unlike Lumen’s specific 12-hour or 24-hour options.

A key distinction is that Lumen’s service includes unlimited domestic long-distance calling, a feature not applicable to Granite’s analog overlay model. Lumen is available in the US and select international markets, while Granite’s service is available nationwide in the US.

Other Key Features Compared

Geographic Coverage

Lumen operates on a global scale, with a network that spans 60 countries. This wide footprint is a key advantage for multinational companies looking for a single provider for their international locations.

Granite, on the other hand, focuses its coverage on the United States and Canada. As an aggregator, they don't have a single public map for their network.

Serviceability is checked for each location using their AccessExpress platform.

SLA

Both Lumen and Granite offer a 99.99% uptime guarantee, known as a Service Level Agreement (SLA), for their dedicated internet services. This is a promise about how reliable your connection will be.

In practical terms, a 99.99% uptime SLA means you should expect no more than 53 minutes of potential downtime over an entire year. This reflects a very high standard of network reliability.

The key distinction is that Lumen’s SLA applies directly to its own network. Since Granite is an aggregator, its SLA for off-net services will depend on the specific partner carrier providing the connection.

Transport Types Available

Lumen operates its own network with 340,000 fiber route miles, giving them direct control over speeds. They can offer a wide range from 10 Mbps for basic business needs up to 100 Gbps for heavy data use.

Granite works differently as an aggregator, meaning they don't own the fiber lines. Instead, they resell services from other carriers, so available speeds will depend entirely on which providers are available at your specific address.

This means Lumen can be a great fit for businesses needing guaranteed high-speed connections, while Granite offers flexibility by shopping multiple carriers for you.

Customer Support

Lumen provides customer support directly as the network owner. You can manage services through their customer portal and contact their teams for any technical help.

Granite’s support is based on its role as an aggregator. They offer a single point of contact to manage all the different carriers they use for your services.

Your choice depends on what you prefer: dealing directly with the network owner (Lumen) or having a single team manage multiple providers for you (Granite).

Final Verdict: Lumen Technologies or Granite?

The choice between Lumen and Granite comes down to their fundamental business models. Lumen is a direct network owner with a massive global fiber footprint, giving them end-to-end control over their services.

This makes them a strong fit for large enterprises that require high-capacity circuits and consistent service across international locations. If you prioritize direct network ownership and global reach, Lumen is likely the better choice.

Granite, on the other hand, is an aggregator that manages services from multiple carriers. They are an excellent option for businesses in the US and Canada that want to simplify vendor management and have a single point of contact for all their telecom needs.

Ultimately, your decision depends on whether you value direct network control or the convenience of a managed, multi-carrier solution. To see how they stack up for your specific locations, we recommend using our free questionnaire for real-time quotes.
