What is MDR?
Managed Detection & Response (MDR) is 24/7 threat detection and response by an external team of security analysts. DEFION monitors your endpoints, network, cloud and email environment. AI correlates millions of events per day and filters 99% of noise. Our analysts validate alerts and take immediate action on confirmed threats. Average detection time: under 4 minutes.
Why organisations outsource their SOC
Your team can't staff a 24/7 SOC
An effective in-house SOC needs 6 to 8 full-time analysts for 24/7 coverage, including night shifts and holidays. Certified security analysts are scarce and expensive in the current market. Most security teams are already saturated with day-to-day operations.
You lose control when you outsource security
Most MDR providers copy your log data into an external cloud. You do not know what they do, your data sits in a black box and leaving means losing data. For organisations under GDPR, NIS2 or DORA this is a showstopper.
Generic detection generates too much noise
Out-of-the-box detection rules generate hundreds of alerts a day, the majority false positives. Your team gets overwhelmed, real threats get lost in the noise and trust in the system erodes.
Four traits that set us apart
No other EU MDR provider combines all four of these.
Data in your own Azure tenant
Unique in EU marketWe work via Azure Lighthouse directly inside your environment. Your data never leaves your tenant. Fully compliant with GDPR, NIS2 and DORA. When you leave, you take everything with you. No data loss, no migration.
Detection-as-Code via CI/CD
Technical differentiatorDetection rules are code: version-controlled, documented and reproducible. You can review, audit and export every detection rule. Transparency instead of a black-box SOC.
DFIR DNA in the SOC
