Endpoint protection no single server can turn against you.
Prismara Endpoint Security detects and blocks attacks on every device and brings alerts and incidents together in one XDR hub, replacing Microsoft Defender for Endpoint and Defender XDR. Every response action needs a person's passkey approval and every policy needs two of three custodian signatures, so a compromised server cannot act alone. Run it alongside Defender, then switch over by signed policy when you are ready.

What Prismara Endpoint Security does
See what really happens
eBPF probes record process, network and kernel-module activity at kernel level on Linux 6.8 and later.
Stop attacks, not just log them
BPF LSM programs block malicious execution and protect the sensor itself from being disabled.
One hub for every incident
Alerts and incidents for all your devices come together in the XDR hub, the role Defender XDR plays today.
Built for Prismara SOC
With Prismara SOC, signed and pseudonymised data flows to SOC as your SIEM, and incidents stay in sync both ways.
Response with a human in the loop
Isolating a device or quarantining a file needs an operator's passkey approval. Automatic actions run only from playbooks signed by the custodian quorum.
Your analysts, your names
Your own analysts see real identities. SovSec operators see pseudonyms unless you choose to grant access.
Switch at your pace
Start alongside Defender with no disruption, then hand over protection by signed policy once you are confident.
How it's secured
Prismara Endpoint Security follows the engineering rules shared across the suite, plus these product-specific measures.
Custodian quorum
Three hybrid Ed25519 and ML-DSA-65 custodian keys; two must sign every policy bundle.
The hub only relays
The hub passes approved actions to devices but cannot create them.
Post-quantum by design
Hybrid post-quantum signatures on policy, and data sealed with hybrid ML-KEM-768 and X25519.

Want SovSec to run it for you?
SovSec provides managed security, SOC and Microsoft 365 services for organisations in the UK and DACH region, and can run Prismara as part of that service.
