Three differences matter. First, display latency: we use IVSHMEM shared memory between the VM and the host, which delivers sub-5ms latency with no encoding artifacts. Citrix, Horizon, and WorkSpaces encode pixels to video and stream them over the network, which lands at 50 to 100ms.

Second, memory encryption: we use AMD SEV-SNP so each VM's RAM is encrypted with a hardware key that even the hypervisor administrator cannot read. The others do not encrypt VM memory in use by default.

Third, licensing: per user, per month, with no per-session metering, bandwidth fees, or storage overage. No vendor lock-in because the entire stack is open source.

Minimum 50 users per deployment and a 12-month commitment with a quarterly review option. After Month 6 you can terminate with 90 days notice and no penalty. You can add or remove users monthly as long as the deployment stays at or above 50 users.

Yes. Three options. Our hardware: we provision and manage dedicated servers, and licensing covers infrastructure. Your hardware: we deploy our software stack on your servers, and licensing covers software and management only at a lower per-user price. Hybrid: a mix of both under one management plane with the same SLAs.

The choice is usually driven by data residency rules or existing capex.

ZFS takes a copy-on-write snapshot of each user's data disk every five minutes. The snapshots are immutable, which means malware running inside the VM cannot delete or modify them.

We also run real-time entropy monitoring via eBPF and Falco. When a process writes a large volume of high-entropy data to disk, we treat that as ransomware behavior and trigger an automatic rollback to the last clean snapshot. The 28-second figure is the full restore time for a 200 GB data disk. RPO is under five minutes.

Yes, with caveats specific to each framework. DPDP Act and RBI data localization are handled by deploying nodes in India and configuring data residency to prevent cross-border transfer. UAE NESA and IAS alignment is configurable per tenant.

ISO 27001 and SOC 2 Type II controls are built into the platform with audit-ready logging. HIPAA and PCI DSS require additional configuration depending on the workload, which our team handles during deployment. GDPR is supported via configurable data residency and tamper-proof audit trails.

All audit logs are append-only with cryptographic chaining and retainable up to seven years.

For a 100-user deployment, TCO over three years typically lands at 35 to 50 percent of equivalent physical workstation cost, depending on the user profile.

The savings come from longer hardware refresh cycles on the client side (thin clients last 8 to 10 years versus laptops at 3 to 4), reduced IT support hours because the desktop image is centrally managed, lower endpoint security spend because the attack surface moves server-side, and zero data loss costs from device theft or loss.

We provide a written TCO model as part of the discovery phase.

Because the entire stack is open source (KVM, OpenStack, OVN, Ceph, ZFS, Wazuh, Grafana, eBPF tooling), there is no proprietary format lock-in.

We provide complete exports of golden images, user data disks, configuration files, and Terraform infrastructure code. You can rehost the stack on your own hardware, transfer to another integrator, or migrate to a different VDI platform. The 90-day post-termination cooperation period is included in the standard contract.

We use a phased rollout over six to eight weeks. Weeks 1 to 2 cover discovery and architecture design. Weeks 2 to 4 build out the infrastructure and golden images in parallel. Weeks 4 to 5 run a 10 to 15 user pilot for performance benchmarking. Weeks 5 to 6 migrate the rest of the user base in batches of 25 to 30, with parallel running against legacy systems for a safety net. Week 6 to 8 is stabilization and support handover with a 30-day hypercare period.

Most users transition without measurable productivity loss because the user experience on day one is indistinguishable from a local desktop.

Yes. Because the desktop runs server side and the client only displays pixels, hardware requirements are minimal. Native clients work on any laptop made in the last decade with 2 GB RAM and 100 Mbps. The browser portal works on Chrome, Firefox, Edge, or Safari at 50 Mbps. Thin clients including Raspberry Pi 4+ work at full performance.

We have deployments in environments with 4G mobile uplinks and the user experience remains usable for light tasks like email and document editing. Heavy workloads like video conferencing and 3D CAD benefit from a dedicated 100 Mbps connection.

Four mechanisms layered together. AMD SEV-SNP encrypts VM memory with a hardware key the hypervisor administrator cannot read, so even root access to the host does not expose user data.

Audit logs are written to append-only storage with cryptographic chaining, so an administrator cannot edit logs to cover tracks. Role-based access control separates user management, server configuration, and audit review across distinct roles with no single super-admin handling all three. Session recording is available for compliance-sensitive roles, capturing screen activity for retroactive review.

The combination makes successful insider abuse measurable and traceable.

Both modes are available per group policy. The default for security-conscious environments is locked down: users get a golden image with a curated application set assigned by their group, and they cannot install new software.

For developer or power-user groups, you can allow installations within the user's data disk while keeping the OS disk read-only and ephemeral. Either way, applications installed centrally on the golden image propagate to all users at next login, and image versioning lets you roll back instantly if an update causes issues.

Schedule a pilot via the contact form on this page or email contact@revinfotech.com. A pilot is typically 10 to 15 users for three to four weeks, with real workloads under production-grade configuration.

We benchmark display latency for your specific applications, validate compatibility with your line-of-business software, produce a written compatibility report, and walk through TCO modeling. Pilots run on RevInfotech hardware so there is no setup cost to your side. Decision usually happens within two weeks of pilot completion.
