Cisco AnyConnect (now part of Cisco Secure Client) is the enterprise VPN standard that runs on Cisco ASA and Firepower appliances: deployed by more Fortune 500 companies than any other VPN product, but with licensing complexity and infrastructure requirements that make it overkill for most SMBs.
Best for: Enterprises already running Cisco ASA or Firepower firewalls that need an enterprise-grade remote access VPN with device posture assessment, per-application VPN tunneling, and integration with Cisco I
Cisco Meraki SD-WAN is the cloud-managed networking platform that makes multi-site SD-WAN deployment operationally simple through a single-pane-of-glass dashboard: strongest for distributed enterprises with 10-10,000 branch sites where IT staff at each location is minimal or nonexistent, but with per-device licensing costs that add up at scale.
Best for: Distributed enterprises with 10-10,000 branch locations that need centrally managed SD-WAN, security, and switching without dedicated network engineers at each site. Retail chains, healthcare systems,
Cloudflare One delivers SASE (SD-WAN, ZTNA, SWG, CASB, DLP) through Cloudflare's global network of 300+ data centers: built on the same infrastructure that handles 20%+ of global web traffic to provide the lowest-latency cloud security edge, with a developer-friendly approach that contrasts with traditional enterprise networking complexity.
Best for: Modern, cloud-first organizations that want to replace VPN concentrators and legacy firewalls with a SASE architecture delivered through the world's most distributed edge network. Particularly strong
Fortinet Secure SD-WAN integrates SD-WAN directly into FortiGate next-gen firewalls, eliminating the need for separate SD-WAN appliances and delivering the strongest security-first SD-WAN approach in the market, with the tradeoff that the platform carries FortiOS configuration complexity and requires FortiGuard subscription licensing.
Best for: Security-conscious enterprises already running FortiGate firewalls at branch sites that want to add SD-WAN without deploying separate appliances. Organizations where security teams drive the SD-WAN de
NordLayer (from the NordVPN team) provides cloud-delivered business VPN and ZTNA with the simplest onboarding in the category, deploy in under an hour with published pricing from $8/user/month, purpose-built for SMBs that need secure remote access without enterprise networking complexity.
Best for: SMBs and mid-market organizations with 10-500 employees that need to secure remote access quickly without dedicated network security staff. Strongest for companies replacing consumer VPN or no-VPN acc
OpenVPN Access Server is the commercial VPN platform built on the open-source OpenVPN protocol, providing a web-based management UI, LDAP/RADIUS/SAML authentication, and multi-platform client support on top of the most widely deployed VPN protocol in the world, with self-hosted deployment that gives organizations complete control over their VPN infrastructure.
Best for: IT teams that need a self-hosted VPN platform with full control over the VPN infrastructure, particularly organizations with compliance requirements that mandate on-premises VPN termination, teams alr
Palo Alto Prisma SD-WAN (formerly CloudGenix) integrates with Prisma SASE and Prisma Access to deliver a security-first SD-WAN with application-defined policies: strongest for enterprises already invested in the Palo Alto ecosystem, but with premium pricing and integration complexity that requires significant Palo Alto platform expertise.
Best for: Enterprises already running Palo Alto next-gen firewalls and Prisma Access that want to extend their security platform to SD-WAN without introducing a new vendor. Organizations where the network secur
Perimeter 81 (now Check Point SASE) provides cloud-delivered ZTNA, SWG, and FWaaS with a UI-first approach that makes SASE accessible to mid-market IT teams without dedicated network security engineers, though the Check Point acquisition has introduced product roadmap uncertainty.
Best for: Mid-market organizations with 50-500 employees that need to replace traditional VPN with cloud-delivered ZTNA and SWG without the complexity of enterprise SASE platforms like Zscaler or Palo Alto. Str
HPE Aruba EdgeConnect (formerly Silver Peak) is an enterprise SD-WAN platform with WAN optimization built into the SD-WAN fabric: unique in the market for combining real-time path conditioning, TCP acceleration, and data deduplication alongside SD-WAN routing, though HPE's acquisition has complicated the product roadmap and go-to-market.
Best for: Enterprises with 50-5,000 branch sites that need SD-WAN with built-in WAN optimization, particularly organizations replacing MPLS circuits where WAN optimization was previously delivered by dedicated
Tailscale is a mesh VPN built on WireGuard that creates encrypted peer-to-peer connections between devices without managing VPN servers. The simplest way to connect distributed infrastructure and remote teams, with a generous free tier and pricing that starts at $5/user/month.
Best for: DevOps and engineering teams that need to connect distributed infrastructure (dev environments, CI/CD runners, staging servers, databases) across cloud providers and on-premises without managing VPN s
VMware VeloCloud (now Broadcom) is the carrier-grade SD-WAN platform deployed by 150+ service providers globally, offering the widest range of deployment models (hardware, virtual, cloud-hosted) and the deepest carrier integration, but Broadcom's acquisition has introduced pricing uncertainty and partner ecosystem disruption.
Best for: Enterprises with 50+ branch sites that need carrier-grade SD-WAN with the flexibility to deploy hardware appliances, virtual edges, or cloud-hosted gateways depending on the site profile. Particularly
WireGuard is the modern open-source VPN protocol that has become the performance standard (4,000 lines of code versus OpenVPN's 100,000+, with cryptographically simpler and faster tunneling), but it is a protocol and kernel module, not a managed VPN product, requiring additional tooling for enterprise management.
Best for: DevOps engineers and Linux administrators who want the fastest, most secure VPN tunneling available and are comfortable configuring it manually or integrating it with management tooling. Site-to-site
Zscaler Private Access (ZPA) is the market-leading zero-trust network access platform that replaces traditional VPNs with inside-out connectivity (applications are never exposed to the internet, and users connect through Zscaler's cloud broker), but it is a ZTNA/SDP product, not a full SD-WAN replacement for site-to-site networking.
Best for: Enterprises replacing legacy VPN concentrators with zero-trust application access for remote and hybrid workforces. Particularly strong for organizations with 500+ remote users accessing private appli
The rest of the SD-WAN software category, listed because the enterprise filter above did not select them. Worth reading when the highlighted options do not fit.
The licensing unit is the thing to understand first about PRTG, because each monitored metric or interface counts as a sensor. The server component installs on Windows only, and protocol support covers SNMP, WMI, NetFlow, and REST APIs. SMB and mid-market teams often run it as one platform in place of separate network and server monitoring.
Common questions about enterprise SD-WAN platforms
What defines enterprise-grade SD-WAN?
+
Application-aware routing across multiple WAN links, centralized orchestration with zero-touch provisioning, integrated security (NGFW, IPS, URL filtering), multi-tenant management, sub-second failover, and analytics covering application performance across all sites.
SD-WAN vs SASE: what should enterprises choose?
+
SASE (Cato, Zscaler, Palo Alto Prisma) combines SD-WAN with cloud-delivered security. Traditional SD-WAN (VeloCloud, Fortinet) keeps security at the branch. SASE is simpler for cloud-first organizations. Traditional SD-WAN is stronger for on-premises application traffic.
How does enterprise SD-WAN pricing work?
+
Appliance cost ($1,000-$5,000/site), licensing ($200-$1,000/site/year), and circuit costs. SASE models (Cato, Zscaler) charge per user or per Mbps. At 100+ sites, expect $500K-$2M/year for the SD-WAN layer alone, excluding WAN circuits.
