Best Business Internet & Networking for Businesses Replacing MPLS

Why Replacing MPLS Is Different From a Standard Network Upgrade

MPLS migrations aren't simple swaps. Your existing MPLS circuits probably carry predictable, low-latency traffic between offices, data centers, and sometimes cloud environments — with SLAs your operations team has come to depend on. Moving off that infrastructure means finding a replacement that can match those performance guarantees, not just fill the bandwidth gap.

The business case for leaving MPLS is usually cost and agility. MPLS is expensive per-Mbps, slow to provision new sites (weeks to months), and wasn't designed for cloud-first traffic patterns. SD-WAN, Network as a Service (NaaS), and SASE platforms offer faster provisioning, lower cost per bit, and better handling of SaaS and cloud traffic. But "cheaper" only holds if you scope the full replacement correctly — including any overlay infrastructure, security stack changes, and IT management overhead.

The biggest risk in an MPLS replacement is underestimating complexity. You're not just swapping a circuit; you're likely changing your routing architecture, your security perimeter model, and potentially your support model too. The right provider depends heavily on whether you want to own that complexity or pay someone to manage it for you.

What to Prioritize in Your Evaluation

1. Performance SLAs on the replacement network Broadband-based SD-WAN is cheaper but introduces variable latency and packet loss. If you have latency-sensitive applications (VoIP, real-time ERP, trading systems), prioritize vendors offering a private backbone or explicit SLA commitments — not just best-effort broadband bonding.

2. Global vs. domestic footprint If your MPLS connected international offices, confirm the replacement vendor has PoPs or backbone coverage in those regions. Many SD-WAN vendors rely on public internet outside the US, which can degrade performance significantly for APAC or EMEA locations.

3. Managed vs. self-managed Some vendors hand you a portal and CPE devices; others run the network end-to-end for you. If your IT team is small or already stretched, a fully managed service with a dedicated NOC is worth paying for. If you have strong network engineers, a DIY platform gives more control and lower cost.

4. Security convergence MPLS was implicitly trusted as a private network. SD-WAN over the internet is not. Evaluate whether the vendor includes firewall, ZTNA, SWG, or CASB capabilities — or whether you'll need to bolt on a separate security stack. That adds cost and complexity if not planned upfront.

5. Migration support and parallel running Ask specifically how the vendor handles cutover. Can you run MPLS and SD-WAN in parallel during transition? Do they provide migration planning support, or is that on you? Vendors with strong onboarding programs reduce the risk of a disruptive cutover.

Providers That Fit Best

Aryaka is the strongest fit for global enterprises that want MPLS-level performance without MPLS pricing. Their fully managed SD-WAN runs over a private global backbone with end-to-end SLAs, dedicated NOC support, and proactive monitoring. You're essentially getting a managed service that closely replicates what MPLS delivered — just cheaper, faster to provision, and cloud-aware. Best for companies with 10+ locations including international sites and an IT team that wants the network off their plate.

Cato Networks is the best fit if you want to consolidate networking and security in one move. Their SASE platform replaces both your MPLS and your branch security stack (firewalls, proxies) through a single cloud-native platform. It's well-suited for distributed enterprises with many branch offices replacing both appliances and circuits simultaneously. You get strong visibility, consistent policy enforcement, and a single vendor relationship. Requires more internal configuration ownership than Aryaka.

Graphiant is worth serious consideration if predictable pricing and fast provisioning are your top priorities. Their Network as a Service model gives you a private-backbone alternative to MPLS with straightforward per-site pricing and no complex appliance management. Particularly strong for mid-market enterprises that found MPLS contracts confusing and want a cleaner commercial model. Less full-featured on the security side, so plan for a complementary security tool.

Red Flags to Watch For

• Vendors that can't show you backbone topology for your key regions. "We use the internet with optimization" is not an MPLS replacement for latency-sensitive apps.
• No parallel migration support. Any vendor expecting a hard cutover with no overlap period is a risk.
• Underspecified SLAs. "Up to 99.9% uptime" with no latency or packet loss commitments doesn't protect your operations.
• Hidden CPE costs. Some vendors advertise low monthly fees but charge significantly for hardware per site. Model the total 3-year cost, not just the circuit fee.
• Security gaps glossed over. If a vendor doesn't address how you secure traffic once it leaves the private network, press harder or look elsewhere.

Practical Next Step

Before contacting any vendor, document your current MPLS inventory: number of sites, locations, bandwidth per site, latency-sensitive applications, and monthly spend. Then request a proof-of-concept or pilot for your two or three most complex sites — not just a demo. Any serious vendor will support a paid or free pilot. If they won't, that tells you something.
