AI cyber defence for Australian businesses.
For businesses on Microsoft 365 or Google Workspace. The waitlist is open now.
Console preview with sample data.

Capabilities
What Jetstone will do
Designed for Australian businesses with 1 to 200 devices.
No kernel driver
A light agent that will run on Windows 10 and 11 and on macOS 13 and later.
Named attack techniques
Rules will be mapped to MITRE ATT&CK, so each finding names the technique it matched.
Action on a published list
It will end the process, quarantine the file, isolate the device or sign the user out.
Identity threat watch
A risky sign-in will be matched to the managed device behind it, or marked unmanaged.
Alerts you can read
Each will say what happened, what Jetstone did and what is waiting on you, in plain English.
Made for small teams
A phone-sized console, a Monday summary and an incident export for a broker or insurer.
Detection and response
How Jetstone responds
One sample incident, from the rule match to the write-up.

ConfidenceHigh, 09:57:52
Ended process tree

Updates still reach it, automatic, 09:58:16
Written 09:58:20Goes to Nina by email and SMS
In this sample, a spreadsheet attached to a fake remittance email runs a script that tries to read sign-in secrets from memory. Jetstone will stop the script, quarantine its two files and isolate the laptop before anything leaves it.
Detected
09:57:51A detection rule will match the activity on the device and open an incident.
Scored
09:57:52The finding will be scored, and only a high-confidence score will act on its own.
Process ended
09:58:14The process tree behind the activity will be stopped on the device.
File quarantined
09:58:15The files it brought in will be locked away with their hashes recorded.
Device isolated
09:58:16The device will be cut off from the network, with updates still reaching it, until you release it.
Written up
09:58:20The incident will be written up in plain English, and anything left for you will arrive as an approve or dismiss card.
Every automatic action will be undoable in one tap.
Identity
Sign-ins watched beside the devices
- Impossible travel, MFA fatigue, malicious inbox rules and risky OAuth consents will be flagged.
- A flagged sign-in will be able to end the user’s session in Microsoft 365 or Google Workspace, with one tap to approve.
- Each flag will name the user, where the sign-in came from and the device it used.

Deployment
Built for the systems you already run
An agent on each Windows and Mac device, a connection to your sign-in platform, and detection in one Australian region.

Policy presets
Choose what runs on its own
Three policy presets, Watch, Guard and Lockdown, with fixed isolation guardrails.
| Action | Watch | Guard |
|---|---|---|
| End a process and quarantine the file | Waits for your tap | On its own at high confidence |
| Isolate a device | Waits for your tap | On its own for ransomware or credential theft |
| Sign a user out | Waits for your tap | On its own when compromise is confirmed |
| Medium-confidence detections | Written up and sent | An approve or dismiss card |
| Low-confidence detections | Written up and sent | An approve or dismiss card |
Lockdown
The strictest of the three presets will join Watch and Guard at launch, with its settings published then.
Jetstone will never isolate more than half of a fleet. Under every preset, the device you enrolled from will never be isolated without a second confirmation.

Data residency
Where your data will be held
Built in Australia. Data will be held in Microsoft Azure Australia East.
