About AT&T

AT&T sells business networking and security services, including AT&T Dynamic Defense with Palo Alto Networks, which delivers AI-driven threat prevention as a fully cloud-based service.^[1]

AT&T Dynamic Defense with Palo Alto Networks is delivered as a fully cloud-based service with end-to-end provisioning and operational support backed by both AT&T and Palo Alto Networks. AT&T says AI-powered detection helps stop malware, ransomware, phishing, and command-and-control traffic before it reaches users. Automated blocking and mitigation in AT&T Dynamic Defense with Palo Alto Networks act at the first indicator of compromise.

AT&T says AT&T Dynamic Defense with Palo Alto Networks helps organizations simplify the managing of separate networking and security platforms in an integrated cloud security model. AT&T Dynamic Defense with Palo Alto Networks combines AT&T networking and Palo Alto Networks Prisma Access to bring secure cloud access for users, branches, and applications. In this service, Palo Alto Networks Prisma Access can help enable secure access to private applications without users needing to be connected to the internal network. Strata Cloud Manager applies consistent security policies across users, branches, and locations. SPI is a type of integration that lets a service provider like AT&T connect its network directly to the Prisma Access infrastructure.

On firewalls, AT&T says AT&T Dynamic Defense with Palo Alto Networks can reduce the need for traditional hardware-based firewalls among distributed users and branches. Customers may use the service alongside existing firewalls when transitioning. AT&T Threat Intelligence helps secure AT&T customers in the same way AT&T secures its own infrastructure and digital assets. AT&T points to AT&T Dynamic Defense, AT&T SASE, and AT&T SD-WAN as its cybersecurity solutions.

AT&T Dynamic Defense with Palo Alto is available only to AT&T business customers that maintain or newly establish at least one active AT&T wireless or wireline service connection. Customers may use it with wireless and wireline services provided by other carriers or service providers. AT&T describes a use case in which AT&T Dynamic Defense with Palo Alto Networks helps reduce the risk of care disruptions and sensitive data exposure across hospitals and clinics.

AT&T Switched Ethernet on Demand is an on-demand private connection powered by AT&T's high-speed fiber network, with optional embedded threat detection, secure cloud access, and smart traffic control. AT&T provides a customer port connection at each location, with a standard Ethernet interface of 100 Mbps, 1 Gbps, 10 Gbps, or 100 Gbps. The port is connected via fiber to an AT&T core Ethernet switch that is part of AT&T's nationwide fiber network. Customers can scale, provision, and change network configurations with a self-service portal and only pay for the bandwidth they use. AT&T Dynamic Defense is available with AT&T Business Fiber, AT&T Dedicated Internet, and select customers of AT&T Switched Ethernet on Demand.^{[1][4][5][12]}

AT&T sells business internet as well as security products. AT&T Business Fiber comes with no data caps, no equipment fees, and no annual contract. For AT&T Dedicated Internet, equipment may be provided by AT&T or, where eligible, supplied by the customer.^[12]

AT&T Private 5G Edge is designed to be an integrated platform providing connectivity and embedded applications through a single platform, using CBRS spectrum and/or AT&T spectrum. AT&T says it is being developed for mid-size companies or large organizations with distributed facilities. AT&T says the service complements the existing Azure Public MEC service, which AT&T co-created with Microsoft.^{[1][3][4][12]}

About Cato Networks

Cato Networks sells the Cato SASE Cloud, a SASE platform built as a global cloud with a single-pass engine, a single data lake and single policy enforcement. Cato Networks describes its SASE platform as converging networking, security and access into a single, global, AI-powered cloud service. Cato Networks states that the platform delivers secure, optimized access from distributed points of presence close to users and business resources.^[15]

Cato Networks states that day-to-day planning, scaling and maintenance depend on specialized, hard-to-find expertise. In the company's account, controls differ across users, sites, datacenters and cloud, leaving gaps as applications migrate. Cato Networks positions its platform as a replacement for point products, with a single policy and console running on an SLA-backed global backbone.^[6][7]

The core of the platform is the Single Pass Cloud Engine, called SPACE. SPACE converges NGFW, threat prevention, and CASB, DLP and ZTNA into one cloud-native stack. Thousands of SPACEs run on bare-metal compute across worldwide PoPs, interconnected by tier-1 carriers. Every inspected flow feeds network, device, user, app and data context into one open data lake that is accessible through the Cato API. Cato Networks says NGFW, CASB, DLP, ZTNA, threat prevention and AI controls all run on a single policy engine.^[6]

On the networking side, Cato Networks carries SD-WAN traffic over a private global backbone. Cato Networks connects sites to the Cato Cloud, where they are managed centrally. For access, Cato Networks offers adaptive, risk-based, zero-trust access to private applications located on-premises or in the cloud. The access methods include ZTNA Client, Enterprise Browser, Browser Extension and Clientless Portal. Cato Networks says these access methods can coexist with current access solutions and be selectively deployed to secure some or all application access.

Cato Networks discovers local, custom and managed agents across the enterprise, including their tools, MCP servers, data access and execution paths. Cato Networks controls prompts, responses, tool calls and tool actions before agents create business impact. Cato Networks says AI security can be deployed independently to protect AI usage and AI agents across the organization. Organizations can run AI Security for Applications on-prem or in their own cloud with AI Security Outposts.^[9][10]

Other modules run on the same platform. Cato DLP offers a catalog of 350+ pre-defined data types covering common use cases for sensitive data, PII, and compliance. The Cato DLP engine inspects all traffic to private applications and SaaS apps. Cato EPP is fully managed through the Cato Management Application. Cato DNS Security inspects all DNS traffic in real time to prevent malicious activity hiding within the protocol, and it blocks DNS requests to malicious destinations before a connection is ever made. The Cato Management Application unifies configuration, monitoring and analytics in a single pane of glass.^[12][13][14]

Cato Networks offers MDR, which delivers zero-footprint detection of persistent threats with no agents or appliances. Cato Networks monitors last-mile ISPs 24×7 at every site. On an outage or performance degradation, Cato Networks works with the ISP to resolve it. For management, customers can choose Cato or a qualified partner to help manage the networking and security environment. For site deployment, the zero-touch Cato Socket deploys quickly at customer premises, by the customer or with Cato and partner remote or on-site support. Customers can self-manage, co-manage with a partner and Cato, or hand over complete hands-free operations.^[15]

On deployment, Cato Networks says zero-touch provisioning and self-service client rollout enable selective deployment by use case, geography, or org unit. Cato Networks says its modular platform coexists with existing infrastructure, allowing gradual adoption. Cato Networks says organizations can start with a specific capability such as SD-WAN, SSE, or ZTNA and expand over time without rearchitecting the environment.^{[6][12][13][14][15]}

About Dispersive Stealth Networking

Dispersive Stealth Networking is described by the company as a lightweight, quantum-resilient overlay that makes communications and data in motion invisible and keeps them running under attack. The company says it strengthens the network and security stack a customer already runs, with sovereign control of critical systems, enclaves, AI workloads, and distributed operations. It secures the communication paths that connect users, applications, agents, models, and infrastructure.^[1][3][4]

Dispersive is a software overlay that runs on the infrastructure a customer already operates. Communications are fragmented and dispersed across dynamic, non-deterministic paths. It runs over transport including internet, 5G, VSAT, MPLS, and cloud backbone. DispersiveCloud is a hosted solution, and a self-host option is also offered. Trusted Cloud Edge (TCE) dynamically splits and secures traffic across multiple invisible paths.^[4][5]

The company describes Dispersive Stealth Networking (Dispersive Holdings, Inc) as a preemptive cybersecurity platform. For its hosted option, it states that it operates on cloud networks, partnering with Amazon Web Services and Azure.^[4][6]

The company states its architecture is FIPS 140-3 compliant and aligned with NIST-standardized algorithms, including ML-KEM. It also says post-quantum protection extends across the data plane and the control plane. Its defense page describes a software-defined transport fabric that combatant commands, mission partners, and federal systems integrators can field on mission-approved or customer-furnished hardware. Its financial services page says it meets standards like PCI DSS and GDPR.^{[1][2][4][5][6][7][8]}
