Modern networks are under pressure from every direction. Apps are more distributed, users are everywhere, and change never stops for modern business needs. You can easily reshape your network with a few focused moves that improve performance, security, and agility without blowing up your architecture.
Rethink the Network for a Hybrid, App-Centric World
Hybrid work and cloud-first apps changed traffic patterns for good. Instead of backhauling to a single data center, your network needs to route directly to where apps and users actually are. That means smarter edge locations, better internet underlays, and policies that follow identities instead of IPs.
Treat your WAN like a product of modern business needs. Define reliability, latency, and security as product features, and measure them. When the network is framed this way, you can iterate quickly and retire brittle point-to-point habits.

Modernize Connectivity with SD-WAN and SASE
The public internet is now the default underlay for many enterprises, and SD-WAN makes it workable at scale. You need consistent performance across sites, and providers like GTT can help tie together SD-WAN, internet, and cloud access. With the right design, you can mix transports, steer by application, and avoid the fragility of single-circuit dependencies.
SASE brings security to the same cloud fabric, so you do not bolt on inspection after the fact. Converging networking and security reduces backhaul, simplifies policy, and gives users a cleaner experience. Elastic capacity on the edge means traffic spikes no longer force emergency hardware buys.
Build a Zero-Trust-Ready Foundation
Perimeter walls are not enough when access can come from any device in any location. Roughly 63% of organizations have fully or partially implemented a zero trust strategy, signaling real momentum behind identity-led controls of modern business needs. This is your cue to standardize on strong authentication, continuous verification, and least-privilege access at every layer.
Map critical user-to-app paths. Put policy enforcement as close to the user and the app as possible. Microsegment sensitive services that require device health checks, and log every decision so your security team can audit and tune without slowing the business.
Optimize the Internet Underlay and Multicloud Paths
Not all paths on the internet are equal. A recent network performance update observed that one major edge provider measured as the fastest in 44% of networks worldwide at the 95th percentile connection time. Use objective telemetry like this to choose upstreams, and keep a second option so you can fail over.
In multicloud, avoid static routes that assume apps live in one place. Build per-application policies that can select the best exit region, egress provider of modern business needs, or private on-ramp based on live conditions. Automate probing so your network learns and adapts without manual tickets.
Simplify Operations with Automation and Observability
Operating models matter as much as hardware. If your teams are clicking through device GUIs, you will fall behind every quarter. Move to intent-based workflows where policies are defined once and pushed consistently across branches, clouds, and users.
Use clear, outcome-focused metrics to guide automation. The following checklist can help you structure day-to-day improvements:
- Define golden signals for each app path
- Automate config baselines and drift detection
- Use synthetic tests from user locations
- Correlate network, security, and app telemetry
- Close the loop with auto-remediation for known faults
Observability should reduce noise. Roll up raw metrics into service health views that executives and engineers both understand. When everyone speaks the same language, change windows get shorter and fewer incidents turn into outages.
Align People, Process, and Partners
Technology only sticks when teams are ready. Upskill network staff on security concepts and give security teams visibility into network policy. Joint runbooks, tabletop exercises, and shared SLOs build muscle memory before a real incident hits.
Choose partners that bring global reach and operational maturity so your team can focus on design and policy. Look for transparent SLAs, live telemetry, and the ability to integrate with your tooling. The right support model shortens mean time to innocence and keeps your engineers on strategic work.
Measure What Matters and Keep Iterating
Pick a small set of metrics that reflect real user experience. Time to first byte, page load time, call quality scores, and successful auth rates tell the story better than interface counters. Publish these in a simple dashboard and review them weekly.
As needs change, tune policies and paths instead of purchasing more boxes. Pilot changes with a small cohort, watch the metrics, and roll forward when results hold. This cycle turns your network into a platform that moves at the speed of the business.
Networks are never finished, but they can be fit for purpose modern business needs. By focusing on identity-first security, smart internet underlays, and automation, you can keep pace with new apps and new work patterns. Start small, learn fast, and keep the experience of your users as the north star.
