Platforms we deploy and manage
Each page below covers one platform in detail — what it does, where it fits, and how OAS deploys and runs it.
Citrix DaaS delivers cloud-managed virtual desktops with hybrid flexibility. OAS, South Africa's longest-standing Citrix Platinum Partner, provides end-to-end deployment and support.
NetScaler ADC provides load balancing, SSL offloading, web application firewall, and AI Gateway capabilities. OAS delivers expert NetScaler deployment and management.
Citrix Virtual Apps and Desktops (CVAD) delivers on-premises application and desktop virtualisation. OAS, Citrix Platinum Partner since 1987, provides end-to-end deployment.
Secure access to your business applications — from any device, any location, any connection. OAS delivers enterprise virtual workspace solutions built on Citrix and Microsoft platforms, managed end-to-end for South African organisations.
The Virtual Workspace Challenge
Your people work from multiple locations. They use company laptops, personal tablets, and home desktops. They need the same applications and data regardless of where they connect from. Traditional VPN access is slow, fragile, and difficult to secure. Desktop provisioning takes weeks. Application conflicts disrupt productivity.
Virtual workspace technology solves this. Your applications run centrally — in your data centre or the cloud — and are delivered securely to any device. Data never leaves your controlled environment. IT retains complete visibility and control. Users experience a responsive desktop that works the same whether they are in Johannesburg, Cape Town, or London.
OAS has been delivering virtual workspace solutions for over 40 years. We deploy both Citrix and Microsoft platforms, matching the right technology to your specific requirements.
The Citrix Portfolio
OAS is a Citrix Platinum Partner — one of the longest-standing Citrix partnerships in Southern Africa. Our Citrix expertise spans three core products:
Citrix Virtual Apps and Desktops (CVAD)
The on-premises foundation for enterprise virtual workspace delivery. CVAD provides full session management, application virtualisation, GPU-accelerated desktops, and the HDX protocol — Citrix's proprietary technology that delivers responsive virtual sessions even over bandwidth-constrained connections. CVAD is the platform of choice for regulated industries requiring complete on-premises control.
Citrix DaaS (Desktop as a Service)
Cloud-managed virtual desktops with hybrid deployment flexibility. Citrix DaaS moves the control plane to the cloud while your workloads run wherever they make the most business sense — on-premises, in Azure, AWS, GCP, or any combination. This is the architecture most South African enterprises need: sensitive workloads remain on-premises for regulatory compliance while remote users scale through the cloud.
Citrix NetScaler
The application delivery controller that ensures your applications remain available, secure, and performant. NetScaler provides Layer 4-7 load balancing, web application firewall (WAF) protection against OWASP Top 10 threats, SSL offloading, and the new AI Gateway for centralised control over AI traffic.
Azure Virtual Desktop (AVD)
For organisations with simpler virtual desktop requirements, Azure Virtual Desktop delivers Windows 11 multi-session desktops on Azure South Africa infrastructure. AVD includes FSLogix profile management for persistent user settings, RemoteApp for individual application publishing, and native integration with Microsoft Entra (Azure AD) for identity management.
AVD runs on Azure's Johannesburg and Cape Town data centres, ensuring POPIA-compliant data sovereignty without additional configuration.
Choosing the Right Workspace
OAS delivers both Citrix and Microsoft virtual workspace solutions. The right choice depends on your requirements:
| Requirement | Citrix CVAD / DaaS | Azure Virtual Desktop |
|---|---|---|
| Multi-cloud flexibility | Azure, AWS, GCP, on-premises | Azure only |
| Session management depth | Enterprise-grade — recording, watermarking, roaming | Basic session controls |
| HDX protocol (bandwidth optimisation) | Yes — adaptive transport, EDT protocol | RDP-based |
| GPU virtualisation (CAD, radiology, finance) | Full support | Limited GPU options |
| Application virtualisation | App Layering, per-app publishing | RemoteApp |
| Cost profile | Premium — enterprise feature set | Cost-effective — simpler environments |
| Ideal for | Regulated industries, complex deployments, multi-cloud | M365-heavy organisations, standard desktops |
OAS helps you make the right decision. Many organisations deploy both platforms — Citrix for power users and regulated workloads, AVD for standard knowledge workers.
