One platform, three places it has to work
Spharaka Sphere™ covers the enterprise estate, EdgeProtect™ holds the endpoint, and Signal™ reaches into industrial networks that cannot be scanned. They are not three products that integrate. They are one platform with three collection surfaces and one investigation.
Why the split is by environment, not by function
Security platforms are usually divided by function: one product detects, another responds, a third manages cases. That division looks tidy on a slide and produces exactly the integration burden that makes security operations expensive, because a single incident has to be handed between products that each hold a partial view of it.
Spharaka divides by environment instead, because environment is the thing that genuinely differs. A corporate laptop, a cloud workload and a programmable logic controller cannot be instrumented the same way. The laptop can run an agent. The workload can stream logs and API events. The controller can do neither: it cannot take an agent, it usually cannot be scanned without risk, and stopping it to apply a patch has a physical cost.
So the collection surface changes between the three products, and nothing else does. The reasoning, the case, the policy envelope and the evidence trail are shared. An analyst investigating a compromised engineering workstation that reached a plant network sees one case, not an endpoint alert in one console and an OT anomaly in another.
What each product covers
Spharaka Sphere™ is the core. It unifies SIEM, SOAR, XDR and EDR into a single system: universal log collection across hybrid and multi-cloud estates, correlation into events rather than alerts, autonomous investigation that assembles an evidence chain, and response executed through playbooks generated per incident. It is the product the capability pages describe, and the one the other two feed.
Spharaka EdgeProtect™ is the endpoint half, where speed matters more than anywhere else because encryption starts locally. It provides application control, ransomware protection and one-click containment, and it is what lets a containment decision made centrally take effect on a device in seconds rather than through a ticket.
Spharaka Signal™ is the industrial estate. Collection is passive by default: sensors observe mirrored traffic from a SPAN port, a network tap or ERSPAN and never inject traffic into a safety controller. It reads industrial protocols at register level, so a write that changes a burner setpoint is legible as that rather than as a TCP session on port 502, and it produces continuous compliance evidence against IEC 62443, NERC CIP, NIST SP 800-82r3 and AWWA G430 instead of an audit scramble.
Where the platform runs is part of the product
For most software, deployment topology is a procurement detail settled after the platform is chosen. For an AI-native security platform it is closer to the opposite, because where the model runs determines what the platform can be asked to do with your data.
A platform that reasons about incidents at a public API cannot reason about telemetry you are not permitted to send there, which in regulated sectors is most of it. Sphere On-Premises runs SAGE™ inference locally, inside your own data centre, so an air-gapped deployment loses no capability rather than degrading to log storage with a rules engine. That is what makes the platform usable in defence, in government and in banks whose regulator has a view about data residency.
Cloud, hybrid, on-premises and fully air-gapped are all supported topologies, and the deployment models guide sets out what each one lets you ask of the platform, along with the trade-offs that come with each.
Where to start
Depending on what you are trying to cover first.
We want the whole security operation on one platform

Our data cannot leave the building, or there is no building-to-internet link
Start with Sphere™ On-Premises and its air-gapped deployment
We have a plant, a substation, a refinery or a water utility to cover
Start with Spharaka Signal™
Ransomware containment speed is the immediate concern
Start with Spharaka EdgeProtect™
Products and deployment
Three products, one air-gapped deployment of the core, and the category page that explains what autonomous means here.
Products
Spharaka Sphere™
The core platform: SIEM, SOAR, XDR and EDR as one system rather than four that exchange tickets.
Spharaka EdgeProtect™
The endpoint: application control, ransomware protection and one-click containment at the edge.
Spharaka Signal™
The industrial estate: passive discovery, register-level protocol semantics and continuous compliance.
Frequently asked questions
What is the difference between Sphere, EdgeProtect and Signal?
They differ by collection surface, not by function. Sphere is the core platform covering the enterprise estate: logs, cloud, identity and network. EdgeProtect is the endpoint agent, providing application control, ransomware protection and containment on the device. Signal covers industrial and control networks passively, reading OT protocols at register level. All three share one model, one case and one policy envelope.
Do I need all three products?
No. Sphere is the platform and the other two extend it into environments it cannot instrument on its own. An organisation with no industrial estate has no use for Signal, and one that already runs an endpoint agent it is happy with can integrate that instead of deploying EdgeProtect. Adding either later does not require a second integration project because the data layer is shared.
Can the platform run entirely on-premises?
Yes, including fully air-gapped, with no outbound connectivity at all. SAGE inference runs locally, so autonomous investigation and response behave the same as in a cloud deployment rather than degrading to log storage with a rules engine. This is the deployment used in defence, in classified networks and where a regulator has a view about data residency.
Does Sphere replace our SIEM?
It can, and many deployments end there, but not on day one. The usual path is to run Sphere alongside the existing SIEM, migrate detections in phases, and decommission once coverage is proven. The AI SIEM Migration guide sets that out, and it is written specifically because migrations run to a single cutover date are the ones that fail.
How does Signal avoid disrupting a production control system?
Collection is passive by default. Sensors observe mirrored traffic from a SPAN port, a network tap or ERSPAN, and never inject traffic into a safety controller. Active OT polling exists but is opt-in and explicitly scoped. This matters because active scanning has caused outages on production control systems, which is why passive-first is the default rather than an option.
