Comcast Business leverages Verizon's 5G network and WiFi hotspots from Comcast/xfinity modems to provide wireless services under the brand name xfinity mobile. This service supports both LTE and 5G, offering multiple plans subject to availability. However, there is no Service Level Agreement (SLA) listed, and fixed wireless options are not mentioned on their website.
Spectrum Enterprise also utilizes Verizon's 5G network along with WiFi hotspots from Spectrum modems for its wireless services, branded as Spectrum Mobile. Unlike Comcast Business, Spectrum Mobile does not support LTE but does offer 5G. Similar to Comcast, Spectrum Enterprise does not list any SLAs or fixed wireless options on their website.
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, while Managed Security provides a range of services including Managed VPN, Unified Threat Management (UTM), and Managed Firewall. These services ensure secure data transmission, robust threat monitoring, and customized firewall rules. Additionally, Comcast Business offers DDoS protection for Ethernet, which mitigates threats without requiring additional configuration.
Spectrum Enterprise, on the other hand, provides security solutions tailored to different business sizes through its Enterprise Network Edge and Managed Network Edge products.

The service operates on a Hybrid Fiber Coax (HFC) network and includes a 99.99% uptime SLA. However, it imposes a utilization cap of 1.2 Terabytes (TB) per month, which could be a limitation for data-intensive businesses.
Spectrum Enterprise provides broadband speeds up to 1 Gbps for downloads and up to 35 Mbps for uploads, also using an HFC network. Notably, Spectrum Enterprise boasts a 100% uptime SLA and offers unlimited data usage, making it an attractive option for businesses with high data demands.

POTS Replacement
Comcast Business Voice and Spectrum Business Voice both offer robust solutions for business communication needs, but they cater to different requirements. Comcast Business Voice is particularly suited for fax, alarm, and point-of-sale applications, aligning with NFPA 72 standards for fire alarm and signaling systems. However, it requires Comcast Business Internet to avoid service fees for unlimited talk and text, and long-distance calls may incur additional charges.
On the other hand, Spectrum Business Voice provides unlimited local and long-distance calling with over 35 advanced business voice features. Unlike Comcast, Spectrum does not require bundling with its internet service, although bundling can offer cost savings. Spectrum's internal battery lasts up to 8 hours, compared to Comcast's 5-hour battery, but it prohibits the use of its service for medical alert systems and fire alarms, which may limit its utility for some businesses.
