SOC L1 monitoring on the SIEM you already run
First-line security monitoring and triage, so alerts are reviewed, filtered and escalated by trained analysts instead of piling up unread.
What Level 1 covers
Alert monitoring and triage
Analysts review alerts as they arrive and decide which ones matter.
False-positive filtering
Noise is separated from real activity so your team is not chasing every alert.
Classification and severity
Each confirmed alert is categorized and rated using an agreed scale.
Escalation by playbook
Confirmed incidents go to your team or to L2 and L3 responders, with the details they need.
Ticketing and shift handover
Every alert is tracked in a ticket, and context passes cleanly between shifts.
Reporting and tuning
Daily, weekly and monthly security health reports, with recommendations to improve detection use cases.
SIEM platforms we work with
Your platform, or one we help you choose.
How onboarding works
- Step 1
Scope and log sources
Agree what is monitored and connect the log sources.
- Step 2
Access and use cases
Set up platform access and the detection use cases that matter to you.
- Step 3
Playbooks and escalation
Define who is contacted, when and how.
- Step 4
Go-live and tuning
Start monitoring, then tune rules to cut noise.
- Step 5
Regular reporting
Review results with you on a set schedule.
Coverage hours, response times and escalation contacts are agreed in your service agreement. Level 1 handles monitoring and first-line triage. Deeper investigation and response are escalated under the agreed playbooks, or handled through our incident response service.
Common questions
Something missing? Ask on the consultation call and we will answer it straight.
Do we need our own SIEM?
You can use one you already run. If you do not have one yet, we can help you choose and set up a platform that fits your size and budget.
What is the difference between L1, L2 and L3?
Level 1 monitors and triages alerts. Level 2 investigates confirmed incidents in depth. Level 3 handles the most complex cases and threat hunting. We provide Level 1 and hand off according to your playbooks.
Can you monitor cloud and endpoints as well as networks?
Yes, as long as the relevant logs are collected in your SIEM. We help connect cloud, endpoint and network sources.
