ISP Products
DIA
Comcast Business offers its Ethernet Dedicated Internet (EDI) with a wide range of speeds from 10 Mbps to 100 Gbps, utilizing fiber, coax, and hybrid fiber-coax transport types. With 200,000 fiber route miles and a 99.99% uptime SLA, it ensures reliable connectivity without utilization caps. Common add-on services include static public IP addresses, BGP routing, managed routers, DDoS mitigation, and more.
Lumen Technologies' Dedicated Internet Access (DIA) also provides speeds ranging from 10 Mbps to 100 Gbps, but exclusively uses fiber for transport. With a slightly larger fiber network of 263,000 miles and the same 99.99% uptime SLA, Lumen matches Comcast in reliability and performance. Their add-on services are similar, offering static public IP addresses, BGP routing, managed routers, and various security solutions.
Wireless
Comcast Business leverages Verizon's 5G network and its own WiFi hotspots to provide wireless services under the brand name xfinity mobile. This service is designed primarily for phones and personal devices, offering both LTE and 5G connectivity. While multiple wireless broadband plans are available, specific details are subject to availability, and there is no Service Level Agreement (SLA) listed for these services.
On the other hand, Lumen Technologies' Wireless WAN service, also known as Enterprise Wireless Access Service (EWAS), utilizes a multi-carrier network that includes T-Mobile, Verizon, and AT&T's 4G LTE and 5G networks. This service is available exclusively in the United States and is intended as a primary or backup access option for enterprises. Unlike Comcast, Lumen does not list specific wireless broadband plans online, requiring customers to engage with a sales representative for details. Similar to Comcast, Lumen does not provide an SLA for its wireless services.
Security
Comcast Business offers a comprehensive suite of security solutions under its Security Edge and Managed Security products. Security Edge acts as the first line of defense against cyberattacks, providing essential protection for businesses. Managed Security includes a range of services such as Managed VPN, Unified Threat Management (UTM), and DDoS protection for Ethernet. These services ensure secure data transmission, robust threat management, and protection against DDoS attacks, all managed by Comcast to simplify security for enterprises.
Lumen Technologies' cybersecurity solutions are designed to protect digital environments with advanced, award-winning security measures. Their Adaptive Network Security platform offers automated threat detection and response, while DDoS Hyper provides self-serve DDoS protection. Lumen Defender, powered by Black Lotus Labs®, secures internet connections with proactive blocking and visibility. Additionally, Lumen's Managed Premises Firewall Services and SASE solutions fortify network defenses, making them a strong contender in the cybersecurity space.
Broadband
Comcast Business offers a robust Broadband Internet service under the name Comcast Business Internet. With speeds ranging from 150 Mbps to 1.25 Gbps for downloads and up to 35 Mbps for uploads, it caters to various business needs. The service operates on a Hybrid Fiber Coax (HFC) network and includes a 99.99% uptime SLA, ensuring reliable connectivity. However, it does come with a utilization cap of 1.2 Terabytes (TB) per month.
In contrast, Lumen Technologies no longer offers a broadband service, making Comcast Business the clear choice for enterprises seeking broadband solutions. With no available speeds, uptime SLA, or transport type listed for Lumen, businesses looking for broadband internet will find Comcast Business to be the more viable and reliable option.
Ethernet
Comcast Business offers a range of asymmetrical broadband internet speeds, from 150 Mbps to 1.25 Gbps for downloads and up to 35 Mbps for uploads. Utilizing a Hybrid Fiber Coax (HFC) network, it ensures a 99.99% uptime SLA but comes with a utilization cap of 1.2 Terabytes per month. This makes it a reliable option for businesses with moderate data needs and a focus on consistent uptime.
In contrast, Lumen Technologies provides a variety of Ethernet services, including E-Line, E-LAN, Ethernet On-Demand, and Metro Optical Ethernet. These services offer scalable bandwidths from 2 Mbps to 30 Gbps and port speeds up to 100 Gbps, catering to businesses requiring high-speed, flexible, and secure connections. With options for point-to-point, multipoint, and on-demand connectivity, Lumen's Ethernet solutions are designed for enterprises with more complex networking needs.
POTS Replacement
Comcast Business Voice is tailored for essential applications like fax, alarm, and point-of-sale systems. It requires Comcast Business Internet to avoid service fees for unlimited talk and text, and offers an optional LTE failover. The service includes a 5-hour internal battery and aligns with NFPA 72 standards for fire alarm and signaling systems. However, it does not include long-distance calling, which may incur additional charges.
Lumen's Cloud Communications Specialty Lines provide a fully managed digital solution for critical safety systems, including alarms and security gates. Unlike Comcast, Lumen's service can operate over third-party internet connections and includes backup cellular connectivity with LTE or 5G networks. It offers more robust battery options of either 12 or 24 hours and includes unlimited local and domestic long-distance calling. Additionally, Lumen's service is available in select international markets, providing broader availability compared to Comcast.
