Loadbalancer.org Enterprise in depth
Read the full write-up
Loadbalancer.org Enterprise is an application delivery controller for organizations running important applications across hybrid or multi-cloud infrastructure. It is best suited to teams that need regional resilience, deep traffic and security controls, and freedom to deploy appliances in their own environment or a public cloud. The trade-off is a substantial perpetual purchase and capacity-based plan selection rather than a simple, low-cost subscription.
Overview
Enterprise handles both Layer 4 and Layer 7 traffic, combining application-aware routing, scheduling choices and health checks. Its global server load balancing can spread requests between regions in active-active or active-passive designs, making it a credible fit for continuity planning as well as ordinary load distribution. TLS termination is supported.
The included web application firewall adds real-time threat mitigation, editable rules, OWASP Top 10 coverage and PCI-DSS Section 6.6 compliance. ACLs, IP filtering, DDoS mitigation, WARP Tunnel support and LDAP/RADIUS authentication extend the control set. TLS support covers versions 1.0 through 1.3, with SNI, OCSP validation, mutual TLS and FIPS 140-2 Level 1.
Key features
Operations teams can administer through a web UI, SSH or physical console, and automate through RESTful and PowerShell APIs. Configuration backup and selective restore help contain risky changes. Prometheus, Grafana, Syslog, NTS, Ansible, Puppet, Chef and Terraform integrations fit monitoring and infrastructure-as-code workflows.
Every Enterprise load balancer includes free ADC Portal access for centralized estate management, including third-party load balancers. Support is available from level 3 specialists, with unlimited security updates, telephone, email, Zoom and chat channels, priority case handling, and either 24/7 or business-hours coverage. Loadbalancer states certifications to ISO 13485:2016, ISO 9001:2015 and ISO 27001:2022.
Pricing
There is no free plan. Pricing starts at $150/mo, and a 30-day trial is offered. The plans combine a one-time perpetual or BYOL amount with the stated billing model, so the initial purchase and ongoing consumption both matter.
Enterprise VA Basic: $2,360, paid once, perpetual, or $150 /mo subscription. It provides 400Mbps throughput, 400 SSL TPS and unlimited servers. This is the entry point for smaller virtual-appliance deployments, but the throughput and transaction ceiling can constrain busy or TLS-heavy services.
Enterprise VA Prime: $4,710, paid once, perpetual, or $280 /mo subscription. It raises capacity to 4Gbps and removes the SSL TPS limit while retaining unlimited servers.
Enterprise GCP, AWS or Azure: each costs $4,710, paid once under BYOL, then $0.55 /hr pay-as-you-go. Throughput and SSL TPS are unrestricted, making these sensible when cloud placement and variable usage outweigh predictable licensing.
Enterprise Prime: $7,390, paid once, perpetual, with 4Gbps throughput and unlimited servers.
Enterprise VA Max: $9,900, paid once, perpetual, or $590 /mo subscription. It delivers 40Gbps and unrestricted SSL TPS for demanding virtual estates.
Enterprise Flex: $14,770, paid once, perpetual, with 48Gbps throughput and unlimited servers.
Enterprise Max: $35,720, paid once, perpetual, with 90Gbps throughput and unrestricted capabilities for the largest stated workloads.
Platforms
Enterprise runs through API, Linux, self-hosted and web interfaces. It is sold as hardware, as virtual appliances for VMware, Hyper-V, KVM, Xen, Proxmox, Nutanix and Red Hat, and as cloud appliances on AWS, Azure, GCP and HPE Private Cloud. That range suits estates that cannot standardize on one infrastructure model.
Who it's for
This is aimed at infrastructure and security teams supporting high-value services across locations, particularly organizations in healthcare, storage, broadcast media, print and education. The company also cites product managers at Fortune 500 corporations. Smaller deployments should compare their expected throughput and SSL load carefully before paying for enterprise capacity.
Pros and cons
Pros
Broad traffic scope: Layer 4, Layer 7 and GSLB cover local routing through multi-region failover.
Serious security coverage: WAF controls, DDoS mitigation, mutual TLS and FIPS 140-2 Level 1 address regulated or exposed services.
Deployment flexibility: Hardware, many hypervisors and three major public clouds reduce platform lock-in.
Operational integration: APIs, configuration recovery, observability tools and automation frameworks support controlled administration.
Cons
High upfront commitment: even the basic perpetual option costs $2,360, paid once, before subscription or cloud usage.
Entry capacity is limited: VA Basic caps throughput at 400Mbps and SSL processing at 400 TPS.
Scaling requires plan selection: higher ceilings carry markedly larger purchase prices, while cloud BYOL adds hourly billing.
Alternatives
F5 BIG-IP APM is a paid, trial-enabled option spanning more client and server platforms, with perpetual licensing available across virtual, hardware and hybrid environments.
VMware Workstation Pro is free on Linux and Windows hosts when the requirement is local virtualization rather than an ADC.
Progress Kemp LoadMaster offers a 30-day free VLM-MAX trial with Enterprise Plus Support, including ESP, WAF and GEO.
A10 Thunder ADC is another paid, trial-enabled ADC for API, Linux and self-hosted deployments.
AWS Elastic Load Balancing is the more natural choice for AWS-native delivery, with a free tier for new customers.
PureLB is a free option for Linux, macOS and self-hosted environments.
Vultr Block Storage provides low-cost cloud storage rather than application load balancing.
Array APV is a paid alternative supporting API, Linux, self-hosted and web deployments.
Verdict
Choose Loadbalancer.org Enterprise when your organization needs one ADC family across appliances, virtual infrastructure and clouds, with regional failover and substantial security controls. Its strongest case is breadth and operational control; look elsewhere if your workload is small, your budget favors usage-only pricing, or a basic cloud load balancer already covers your requirements.
Verdict
Enterprise combines traffic management, security controls and cross-region failover with several deployment choices. Pricing and specifications vary by plan, so the listed throughput and billing terms matter when choosing one.
