Vajra
वज्रthe diamond · the unbreakable — Self-Defending Operating System for Defence Devices
What if a field device that had been quietly turned against you could notice it itself — and lock the intruder out, with no signal and nothing on any virus list?
Defence devices run far from any security team, often cut off — and the attacks that matter are the new ones no scanner has a name for.
The situation
A field radio, deep in a denied area
A handheld in the field is quietly compromised by an implant no signature would catch. Vajra has spent weeks learning exactly how this radio normally behaves. The implant makes the device act in ways it never has — odd processes, odd traffic — and Vajra flags and contains it on the spot, offline, before it can phone home or spread.
How it plays out
Step by step
- 01
It learns the device's normal
On site, Vajra builds a picture of how this exact device behaves when it is healthy — its processes, its calls, its traffic.
- 02
Something acts out of character
A new implant or misuse makes the device behave in ways it never has. Vajra needs no virus name to see it — only the deviation.
- 03
It catches and contains it
The offending behaviour is flagged and isolated, right on the device, with no cloud and no signal needed.
- 04
It can prove what happened
Every decision is deterministic and logged, so the incident can be reviewed and defended afterwards.
The system itself
Under the bonnet
Vajra pairs a locked-down, least-privilege OS baseline with an RSN behavioural monitor that watches a device's own processes, system calls and network patterns. It learns that device's healthy baseline on site, then flags and contains the deviations that mark an intrusion or implant — without virus signatures, a training run, or a connection to any cloud.
What it means for you
The bottom line
- ▸Catches novel, signature-less intrusions by behaviour
- ▸A hardened OS, not a scanner bolted on after
- ▸Learns each device's own normal — works offline
- ▸Deterministic & auditable — every call leaves a record
