What it is
Threat operations is the work of detecting, investigating and responding to attacks: monitoring, threat hunting, threat intelligence and incident response. It runs on a SIEM, the system that collects your security logs and finds the attacks in them. BlueRadius delivers it on Sekoia Defend, either as a managed service or alongside your own team.
The problem
Why most SIEMs disappoint
Costs that grow with your logs
Volume-based SIEM pricing punishes you for collecting the data you need, so teams turn sources off.
Rules nobody maintains
Detections written once, never tuned, and quietly out of date with how attackers work now.
Alerts without answers
A queue of events with no context, and too few analysts to work through it.
The platform
Inside Sekoia Defend
Used by more than 200 SOC teams across 2,000+ organizations, according to Sekoia. Named an Innovator in Frost & Sullivan's Frost Radar: AI SOC (2026), featured in Forrester's XDR platforms landscape (Q1 2026) and named a Leader in the Frost Radar for XDR (2024).
Three detection engines
Correlation rules, threat intelligence matching and anomaly detection, working together.
1,000+ maintained rules
Pre-built detections written and kept current by Sekoia's threat intelligence analysts.
Intelligence built in
Every event is checked against 10 million indicators, with retrohunting when new ones appear.
AI agents for triage
Agents prioritize alerts and guide investigation so analysts start with the ones that matter.
Playbooks
Automated response and remediation that run in the cloud, on premises or both.
Cases and ATT&CK coverage
Investigation and case management, plus a view of which MITRE ATT&CK techniques you detect.

Why BlueRadius
The platform is half of it. People are the rest.
Deployment and migration
We connect your log sources, rebuild the detections that matter from your old SIEM, and run both in parallel until you are ready to switch.
Detection engineering
Custom rules for your environment and business, tuned against real alerts so the queue shrinks instead of grows.
Threat hunting
Analysts searching for attackers who have not triggered an alert yet, using the platform's data and Sekoia's intelligence.
Incident response
Containment, investigation and forensics when something gets through, with a senior responder on the call.
Who it is for
Built for teams that defend
Mid-market companies
That need a SOC without building one from scratch.
Security teams
Replacing a SIEM that costs too much or detects too little.
MSPs and MSSPs
