Your MPLS Renewal Is Not a Renewal Decision
Orange County SMBs with 2–10 locations — manufacturing in Anaheim, clinics in Irvine, multi-site retail in South County — often discover their MPLS contract expires just as their network traffic pattern has shifted from data center to cloud. Renewing MPLS as-is in 2026 means paying premium prices for a routing pattern your users no longer match. SD-WAN and SASE give you better paths, faster deployments, and embedded security, but poor implementations replace one set of problems with another.
Terms, Untangled
SD-WAN
Software-defined WAN that intelligently steers traffic across multiple underlays (broadband, fiber, LTE/5G). It is primarily a networking technology.
SSE (Security Service Edge)
Cloud-delivered security services: Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Zero Trust Network Access (ZTNA), and firewall-as-a-service (FWaaS).
SASE
SASE is SD-WAN plus SSE delivered as an integrated platform. In practice, mature SASE deployments unify policy across users at home, in the office, and in transit.
Signals It Is Time to Replace MPLS
More than 60 percent of your traffic goes to SaaS, not your data center
You have paid for MPLS backhaul to a data center that is shrinking
Remote and hybrid workers need the same security as in-office
Your firewall is refreshing and the renewal is six figures
You are planning a Microsoft 365 or Google Workspace standardization
Architecture Choices for SMBs
Option A: SD-WAN Only, Keep Existing Firewalls
Lower disruption. You keep current NGFWs and add SD-WAN for steering and redundancy. Good fit when you recently refreshed firewalls or need gradual change.
Option B: Full SASE with Single Vendor
Highest integration. One policy plane for users in office, home, and mobile. Simpler operations but potential vendor concentration risk. Good fit when firewalls are due for refresh and security team is small.
Option C: SSE-First, SD-WAN Later
Start with ZTNA, SWG, and CASB to unify security across users, then add SD-WAN at renewal. Good fit for cloud-first teams without heavy branch networking.
Vendor Selection Without the Pain
Short-list 2–3 vendors that match your realities: geographic coverage near your Orange County locations, Microsoft 365 and Zoom route peering, and support hours aligned with your ops. Require a 30–60 day proof of concept with defined success criteria: application performance, security efficacy, failover behavior, and admin experience. Ask explicitly about inspection of TLS 1.3 and QUIC — two protocols where older stacks struggle.
Security You Should Insist On
Full ZTNA with device posture checks for employee access to internal apps
CASB with DLP for Microsoft 365, Google Workspace, Salesforce, GitHub, and any CRM
Secure DNS filtering and SWG coverage off-VPN
Identity-aware policies tied to your IdP (Entra ID, Okta) with conditional access alignment
Integrated IPS and sandboxing with publicly available third-party efficacy tests
Common Mistakes
Renewing MPLS out of inertia. Picking SD-WAN solely on bandwidth-per-dollar without security. Ignoring client peering that drives Microsoft 365 performance. Failing to run a parallel pilot at one site before cutting over. Over-indexing on vendor demos instead of PoC data. Many of these are covered in our IT consulting decision guide.
Migration Timeline
Weeks 1–2: Discovery, traffic profiling, and short-list
Weeks 3–6: Proof of concept at two sites with defined criteria
Weeks 7–10: Pilot production at the top-revenue site with full monitoring
Weeks 11–16: Staged rollout with change windows
Weeks 17–20: MPLS decommission and contract termination
Frequently Asked Questions
Will SD-WAN work on two broadband links?
Yes, often better than single MPLS, if the ISPs are diverse (one cable, one fiber) and SLAs match your needs.
Does SASE replace my firewall?
Typically yes for most use cases, but confirm inspection, HA, and support for industrial or VoIP-specific requirements.
What about small branches with no IT staff?
Zero-touch provisioning is standard. Test the shipping and activation process in the PoC.
Will my VoIP still work?
Yes with QoS properly configured. See our VoIP and business communications post.
