Securing the Edge: Keeping Pace with AI’s Migration

AI Adoption in Small and Mid-Sized Businesses: The Shift to Edge Computing

Presented by T-Mobile for Business

Small and mid-sized businesses are embracing artificial intelligence (AI) at a rate that was once unimaginable. Previously seen as a feature exclusive to large enterprises, AI applications such as smart assistants, predictive tools, and on-site analytics are now being implemented in retail stores, medical clinics, branch offices, and remote operations centers.

The key change lies not only in the AI technology itself but in where it is deployed. Increasingly, AI workloads are moving from centralized data centers to the edge — the physical locations where employees work and customers engage. This shift promises quicker insights and more robust operations but also places new demands on the network. Edge sites require consistent bandwidth, real-time data pathways, and the capability to process information locally instead of relying solely on cloud resources.

However, as businesses rush to connect these dispersed locations, security often lags behind. Devices like AI-enabled cameras or sensors may be adopted before proper security policies are in place. This gap between connectivity and security can lead to unnoticed vulnerabilities, inconsistent access controls, and unmonitored data flows, making it challenging to monitor and safeguard operations.

For edge AI to reach its full potential, connectivity and security must progress in tandem.

Reasons for the Shift to Edge AI and Its Implications

Businesses are transitioning AI to the edge for three main reasons:

• Real-time responsiveness: Certain decisions cannot afford the delay of round-trip communication with the cloud. Immediate actions, such as identifying items, detecting anomalies, or recognizing risks, require local processing to avoid missed opportunities or slow responses.
• Resilience and privacy: Keeping data and inference local enhances operational resilience and privacy, reducing the risk of outages or latency issues while complying with data sovereignty and regulatory demands.
• Mobility and deployment speed: Many SMBs operate across diverse locations, and wireless connectivity, including 5G, enables quick deployment of AI tools without waiting for fixed connections.

Technologies like Edge Control from T-Mobile for Business seamlessly fit into this model. By directing traffic along optimized pathways, businesses can leverage edge AI without compromising network performance.

However, this shift introduces new security risks. Each edge site essentially becomes a mini data center, combining various devices and systems that significantly expand the attack surface, often due to security measures being added as an afterthought.

The Importance of Zero Trust at the Edge

With AI distributed across numerous sites, the traditional concept of a secure internal network becomes obsolete. Every location and device within it poses a potential security risk, necessitating a zero-trust approach for manageability.

At the edge, zero trust entails:

• Identity verification over location: Access is granted based on user or device authentication rather than network location.
• Continuous authentication: Trust is continuously reassessed throughout a session.
• Segmentation for restricted movement: Preventing unauthorized lateral movement across systems in case of a breach.

Given that many edge devices lack traditional security capabilities, solutions like SIM-based identity verification and secure mobile connectivity from T-Mobile for Business play a vital role in securing IoT devices and ensuring network visibility.

Connectivity providers are increasingly integrating networking and security into unified solutions to address these challenges. T-Mobile for Business, for instance, embeds segmentation, device visibility, and zero-trust measures into its wireless offerings, streamlining security for SMBs.

Secure-by-Default Networks: Reshaping Network Security

An architectural shift is underway towards networks that prioritize authentication, segmentation, and monitoring from the outset, combining security and connectivity seamlessly.

Platforms like T-Mobile for Business’s SASE, powered by Palo Alto Networks Prisma SASE 5G, merge secure access with connectivity in a cloud-delivered service. Features like Private Access provide minimal access rights, T-SIMsecure ensures automatic device authentication, and Security Slice isolates sensitive traffic for consistent performance.

A consolidated dashboard like T-Platform offers holistic visibility across SASE, IoT, business internet, and edge control, simplifying operations for SMBs with limited resources.

The Future of Edge AI and Security

As AI models evolve to become more autonomous, the edge will not only support AI but actively run and secure it, optimizing traffic, adjusting segmentation dynamically, and identifying anomalies specific to each location.

Self-healing networks and adaptive policy engines will transition from experimental to standard practice.

For SMBs, this marks a crucial juncture. Organizations that enhance their connectivity and security frameworks now will lead the way in scaling AI securely and efficiently.

Partners like T-Mobile for Business are at the forefront of this evolution, offering SMBs the tools to deploy edge AI while maintaining control and visibility.
