SealGrid is building the air-gapped replacement for the legacy Microsoft System Center suite — running entirely inside your perimeter, with no cloud, no external calls, no exceptions. Its first product, Athena, is a drop-in replacement for SCCM and PDQ: software deployment and inventory under one modern console, with remote control and monitoring built in. Orchestration follows.
Available now — Athena, the SCCM + PDQ replacement
System Center is a constellation of consoles, databases, and connectors stitched together over two decades — and the modern alternatives assume a live link to the cloud. Neither fits a network that must stay sealed.
Athena ships today as a drop-in SCCM + PDQ replacement — deployment, inventory, remote control and rule-based monitoring under one self-hosted console. Orchestration is on the roadmap to complete the System Center replacement.
Package, target, and roll out applications, updates, and patches across every endpoint — with staged rings, dependencies, and automatic rollback. Backed by continuous hardware and software discovery (including the Docker and Podman containers and Hyper-V and VMware Workstation VMs each machine hosts), license posture, and configuration drift detection — a live, queryable source of truth for the whole estate. No internet required.
Take over a machine straight from its device page — through the built-in browser screen share or the optional RustDesk integration, with fleet-wide password rotation and end-user consent prompts. Screen-share sessions can be recorded under a central policy, disclosed to the user, replayed or exported, and pruned automatically.
Rule-based health monitors watch any collected field — services, disks, updates and more — across tagged groups of machines, and raise severity-graded alerts you acknowledge and resolve in one Alerts view. Every device shows its own monitor board with Run Now. Fully on-prem, built for disconnected networks.
Codify runbooks, approvals, and remediation as automated workflows — the SC Orchestrator replacement. Declarative, auditable automation in place of brittle scripting.
How Athena — SealGrid's unified, air-gap-first deployment and inventory product — stacks up against the tools it replaces.
| Capability | SealGrid Athena | Microsoft SCCM | ManageEngine | PDQ Deploy / Inventory | RMM platforms |
|---|---|---|---|---|---|
| Air-gap support | Native, by design | Limited / cloud-attach pressure | On-prem option | Possible, not the focus | Cloud-dependent |
| Software deployment & patching | Staged rings & rollback | Built in | Built in | Built in | Built in |
| Hardware & software inventory | Continuous discovery | Built in | Built in | Separate module | Built in |
| Configuration drift detection | Built in | Via baselines | Config module | Not covered | Not covered |
| Remote actions & scripting | Built in | Via task sequences | Built in | Built in | Core strength |
| Remote control | Screen share + RustDesk, recordable | Built in | Built in | Launches external tools | Core strength |
| Health monitoring & alerting | Rule-based monitors & alerts | Separate product (SCOM) | Separate product | Not covered | Core strength |
| Web Console | Single pane | Multiple consoles | Single pane | Deploy + Inventory split | Single pane |
| Self-hosted & data ownership | Fully self-hosted | On-prem + cloud services | On-prem option | On-prem | Vendor cloud / SaaS |
| Modern stack | Built ground-up | Legacy, decades-old | Broad but heavy | Lightweight, narrow scope | Cloud-native, MSP-focused |
| Built-in compliance & audit (GRC) | Integrated GRC layer | Add-on / manual | CIS benchmarks & audit | Minimal | Minimal |
SealGrid assumes the network is hostile and disconnected. Security isn't a setting — it's the default posture.
No external calls, telemetry, license check-ins, or update servers. SealGrid is designed to operate indefinitely on a fully isolated network.
Every action taken in the console is recorded to an immutable, tamper-evident log built for inspection, forensics, and accountability.
Your data, server, and console live entirely on infrastructure you own and operate. Nothing is processed off-site or by a third party.
Four built-in roles — Admin, Operator, Helpdesk and User — each carry a bundle of granular permissions enforced across the console, REST API and PowerShell, so every operator only does what policy permits — and it's all on the record.
Download the virtual appliance and run it inside your own perimeter, with a built-in trial licence and no internet connection needed. Or try it online first.
