Overview of Lumen Technologies

Lumen Technologies was founded in 1930 and is headquartered in Monroe, Louisiana. The company currently ranks 292 on the Fortune 500 list.

With a team of around 28,000 employees, Lumen operates in 60 countries. The company focuses on building infrastructure to support AI and runs its own cybersecurity threat intelligence team, Black Lotus Labs®.

Its infrastructure is also recognized as the #1 peered global network, a key factor for businesses that depend on high-performance connectivity.

Overview of Frontier Communications

Frontier Communications has corporate roots dating back to 1935. The company is headquartered in Dallas, Texas, and operates across 25 states in the U.S. with a team of around 13,000 employees.

The company focuses on its 100% fiber-optic network, which provides symmetrical upload and download speeds. For its business customers, Frontier includes next-generation Wi-Fi 7 routers with its plans to support high-performance wireless connectivity.

ISP Products

Dedicated Internet (DIA)

Both Lumen and Frontier offer Dedicated Internet Access (DIA) over fiber with speeds up to 100 Gbps and a 99.99% uptime Service Level Agreement (SLA). Lumen operates an extensive 340,000-mile fiber network, while Frontier markets its enterprise and wholesale DIA product as Ethernet Internet Access.

Our proprietary data reveals key differences in installation and pricing. Lumen's average installation time of 68 days is faster than the 77-day market average, while Frontier aligns with the average. For pricing, Frontier is consistently more cost-effective, with its 100 Mbps and 1 Gbps DIA circuits priced 12% and 11% below market rates, respectively. Lumen’s pricing is closer to the average, trending slightly higher for 100 Mbps circuits and slightly lower for 1 Gbps circuits.

Both providers offer a suite of common add-on services, including managed routers and security solutions. Lumen also provides more specialized options like DDoS mitigation and direct cloud connections, which can be important for businesses with specific security or cloud infrastructure needs.

It's worth noting that these are aggregate figures. Actual installation times and pricing can vary significantly based on your region and specific DIA configuration.

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 offers a flexible Wireless WAN service that can be used for either primary or backup connectivity. The service operates on a multicarrier 4G LTE and 5G network, relying on infrastructure from T-Mobile, Verizon, and AT&T.

Frontier, on the other hand, positions its wireless offering strictly as a backup. Its Managed Cellular Failover is part of a larger managed service, designed to keep branch sites online if the main connection goes down, rather than acting as a primary internet source.

While Lumen's service is available across the United States, you'll need to contact a sales representative for plan details and pricing. Frontier's failover solution inherits the Service Level Agreement of the managed service it accompanies.

Security

Lumen Technologies offers a broad portfolio of security solutions, many of which can be purchased as standalone products separate from connectivity. Their services range from DDoS mitigation and Web Application Firewalls (WAF) to more comprehensive options like SASE, all supported by their internal threat intelligence team, Black Lotus Labs®.

Frontier Communications, in contrast, integrates its security features into managed service bundles that are layered onto its dedicated internet product. These packages include features like a managed firewall, web filtering, and remote user VPN. The service comes with 24/7 monitoring and management, creating a more all-in-one security solution for their internet customers.

Broadband

Frontier Communications offers business broadband through its Frontier Business Fiber product, which runs on its fiber network. The service provides symmetrical speeds in tiers up to 7 Gbps in select markets and comes with unlimited data. Frontier cites 99.9% reliability for its small and medium-sized business (SMB) fiber, though the specific Service Level Agreement (SLA) can differ from its enterprise DIA product.

Lumen Technologies also provides broadband services for businesses. Due to limited quoting history in our data set, we’re not able to provide benchmark pricing or installation timelines at this time. For context, the market average installation time for broadband is 28 days.

Since broadband availability and pricing are highly dependent on location, the best way to get current information is to request a direct quote. You can fill out our questionnaire to find the latest pricing and options from providers like Lumen and Frontier for your specific address.

Ethernet

Lumen Technologies has discontinued its Ethernet services, so the comparison centers on Frontier's offerings. Frontier provides Carrier Ethernet within its network footprint for enterprise and wholesale customers, with options for both Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL).

These services are designed for different network architectures. EPL creates a dedicated point-to-point connection between two sites, while EVPL establishes a more flexible point-to-multipoint network. Frontier also offers optical transport services up to 100 Gbps for high-capacity needs.

Importantly, Frontier's Ethernet products are MEF-compliant. This means they meet the Metro Ethernet Forum's standards for performance and interoperability, which is a key indicator of a reliable, carrier-grade service.

POTS Replacement

Both Lumen and Frontier provide solutions to replace traditional Plain Old Telephone Service (POTS) lines for critical systems like alarms, elevators, and security gates. Lumen’s offering, Cloud Communications Specialty Lines, is a fully managed service that can run over any existing internet connection. It includes multi-carrier cellular backup for constant connectivity and offers 12-hour or 24-hour battery packs. Importantly for safety systems, the service is designed to meet NFPA 72 standards for fire alarms.

Frontier’s solution, POTS Connect, is aimed at enterprise customers and supports similar specialty lines over an LTE or wired connection. A key difference is that while Lumen’s service is explicitly NFPA 72 compliant, Frontier does not make this claim on its public-facing materials. Additionally, Lumen specifies its battery backup options and offers service in select international markets, whereas Frontier’s service is limited to its U.S. footprint and does not publicly detail its battery options.

Other Key Features Compared

Geographic Coverage

Lumen Technologies has a significant global presence, with a network that spans over 60 countries. This extensive reach makes them a strong option for international businesses needing consistent connectivity across multiple locations.

Frontier Communications, on the other hand, focuses its operations within the United States. Their network covers 25 states, making them a solid choice for businesses with a domestic presence.

SLA

Both Lumen and Frontier offer a 99.99% uptime Service Level Agreement (SLA) for their Dedicated Internet Access (DIA) products. This is a strong guarantee for business-grade connectivity.

In practical terms, a 99.99% uptime guarantee means your service should experience no more than about 53 minutes of downtime over an entire year.

If the provider doesn't meet this promise, your business is typically eligible for a credit on your monthly bill, providing a financial safeguard for service interruptions.

Transport Types Available

Lumen and Frontier both deliver service over fiber optic networks. Lumen’s network is larger, with 340,000 fiber route miles, compared to Frontier’s 180,000 miles.

Both offer dedicated internet speeds up to 100 Gbps, perfect for large businesses. Frontier also provides symmetrical broadband speeds up to 7 Gbps, great for data-heavy tasks like video conferencing.

Lumen's extensive network suits businesses with a wide footprint. Frontier is a strong choice for high-speed connectivity within its 25-state service area.

Customer Support

When it comes to support, both Lumen and Frontier offer dedicated channels for their business clients. This means you have specific teams to contact for help with your services.

Lumen provides support through its online portal, where you can manage your account and open trouble tickets. They also offer phone support for more direct assistance.

Frontier also has online and phone support options. For customers using their managed services, support often includes 24/7 monitoring, which adds an extra layer of oversight for your connection.

Final Verdict: Lumen Technologies or Frontier Communications?

Choosing between Lumen and Frontier ultimately depends on your business's geographic footprint and how you prefer to purchase services. Both are strong providers, but they cater to different needs.

Lumen is the clear choice for businesses with an international presence, given its network reach across 60 countries. It's also ideal for companies that want to buy specialized security services, like DDoS mitigation, as standalone products.

Frontier is a great fit for US-based companies looking for cost-effective dedicated internet, as our data shows their pricing is often below the market average. Their bundled approach, which combines connectivity with managed security and failover, can also simplify vendor management for your IT team.
