What Netify Thinks
GTT's defining differentiator is its Tier-1 IP backbone ownership. Unlike managed service providers that lease circuits from third-party carriers, GTT owns and operates its own global backbone with 450+ PoPs, keeping approximately 75% of customer traffic on its own network. This infrastructure ownership translates into deterministic performance, fewer hops between enterprise sites, and faster fault resolution for international traffic — advantages that leased-network providers cannot replicate.
Strengths
- Tier-1 backbone ownership: GTT's owned global IP backbone with 450+ PoPs across six continents keeps approximately 75% of customer traffic on-network. This reduces latency through fewer routing hops, improves resilience by limiting dependency on third-party carriers, and provides GTT with faster fault isolation and resolution than network service providers relying on leased circuits.
- ISG Leader in US and UK (2025): Named a Leader for both Managed SD-WAN and SASE in both the United States and United Kingdom by the 2025 ISG Provider Lens — one of very few providers achieving dual-market, dual-category leadership in a single report cycle.
- GTT Envision platform: The Envision platform provides customers with visibility, insights, orchestration, and control across their entire GTT-managed network — a customer-facing analytics and management layer that reduces operational complexity and provides transparency into network performance.
- 400G backbone upgrade: GTT has invested in a phased 400G upgrade of its global Tier-1 backbone, initially covering metropolitan city locations and expanding across its core IP switching and routing fabric. This improves scalability and provides higher-capacity options for bandwidth-intensive enterprise workloads.
- Vendor-agnostic SASE portfolio: GTT's Secure Connect supports both Fortinet-powered and Palo Alto Networks Prisma SASE options, giving enterprise customers technology choice within a carrier-managed delivery model.
Weaknesses
- Moderate domestic market footprint: GTT's market presence in the UK is less comprehensive than BT or Virgin Media Business for UK-domestic deployments. GTT's strength is international connectivity — UK-centric organisations may find BT or TalkTalk Business offer better local service quality and lower costs for domestic-only sites.
- Not in Gartner MQ for SD-WAN or SASE Platforms: GTT does not hold a position in the Gartner Magic Quadrant for either SD-WAN or SASE Platforms. Buyers using Gartner MQ as a primary screening tool will not find GTT on those shortlists and will need to consider ISG and Frost & Sullivan recognition instead.
- Customer service variability: Gartner Peer Insights reviews for GTT Global WAN Services include notable negative feedback around billing, cancellation processes, and customer service responsiveness. This is a consistent theme across reviews and represents an execution risk for enterprise buyers.
- SASE launched relatively recently: While GTT's managed SD-WAN heritage is strong, its Secure Connect SASE offer with Fortinet and Palo Alto Networks is relatively recent. Enterprise buyers should seek reference sites for specific SASE deployment scenarios.
Verdict: GTT Communications is best suited to multinational enterprises that need Tier-1 backbone-backed managed SD-WAN and SASE with deterministic performance for international traffic, particularly those where latency on cross-border traffic is business-critical (financial services, trading floors, media delivery). It is less suitable for UK-domestic-only deployments or buyers prioritising Gartner MQ-positioned vendors.

Frequently Asked Questions
What is GTT Secure Connect?
GTT Secure Connect is GTT's SASE solution that combines managed SD-WAN and Security Service Edge (SSE) capabilities into a tightly integrated framework delivered over GTT's Tier-1 global IP backbone and monitored 24/7 by GTT's operations teams. It is available with Fortinet-powered SSE or Palo Alto Networks Prisma SASE as security options, managed via the GTT Envision platform for visibility, orchestration, and control.
How much does GTT SD-WAN cost?
GTT does not publish standard SD-WAN pricing. Costs are scoped per engagement based on site count, geography, bandwidth requirements, technology platform (Fortinet or Palo Alto SASE), and managed service scope. GTT pricing is reportedly comparable to BT Business for UK deployments, according to independent analysis from Netify's UK SD-WAN comparison research. Request a formal proposal from GTT's enterprise sales team.
Is GTT suitable for UK deployments?
Yes, particularly for UK-based multinational organisations with international site estates. GTT is named a Leader for both Managed SD-WAN and SASE in the UK by ISG (2025) and operates a UK sales and operations team. For purely UK-domestic deployments, BT Business or Virgin Media Business may offer better local service quality and lower costs. GTT's advantage is most pronounced for enterprises with significant international connectivity requirements where its owned Tier-1 backbone provides performance and resilience that leased-network providers cannot match.
How does GTT compare to Colt Technology Services?
Both GTT and Colt are privately owned, globally connected network carriers that deliver managed SD-WAN and SASE services. Key differences: Colt's IQ Network is concentrated in Europe and Asia with deeper on-net building penetration in European financial centres; GTT has more balanced global coverage with 450+ PoPs across six continents. Colt has a higher European NPS (70+) and stronger European enterprise and financial services presence; GTT has stronger North American coverage and ISG recognition in both US and UK markets. For European-heavy enterprise estates, Colt is typically stronger; for US/UK multinationals with diverse international sites, GTT competes effectively.
