SOC Tiering (L1 / L2 / L3)
Structure analyst tiers so alerts get triaged, investigated and resolved at the right level.
A tiered SOC routes work to the right skill level: Tier 1 triages and validates alerts, Tier 2 investigates confirmed incidents, and Tier 3 handles threat hunting, advanced forensics and detection engineering. We define the roles, escalation paths and handover criteria, with playbooks at each level so nothing falls through the cracks. Tiering keeps your senior analysts on hard problems instead of clearing routine noise.
Included in this service
Defined tier roles
Clear responsibilities for Tier 1, 2 and 3 so everyone knows what they own.
Escalation criteria
Written triggers for when an alert moves up a tier, removing guesswork under pressure.
Tier-specific playbooks
Procedures matched to each level, from triage scripts to deep investigation.
Performance metrics
Time to triage, time to resolve and escalation accuracy tracked per tier.

A clear path from problem to outcome
Scope and rules of engagement
We agree targets, objectives and constraints in writing: in-scope assets, test windows, success criteria and emergency stop conditions. You get a signed authorisation and a named point of contact before any tooling touches your environment.
Execute and validate
Our team runs the engagement against agreed objectives, whether that is exploitation, detection validation or a build. Activity is mapped to MITRE ATT&CK where relevant, and we confirm each finding so you receive evidence, not noise.
Report with reproducible proof
Every finding ships with a reproducible proof of concept: request and response, payloads, screenshots and exact steps. Risk is rated by business impact and likelihood, with clear, prioritised remediation guidance your engineers can act on.
Remediate and retest
We walk your team through fixes, answer questions and retest to confirm closure. You finish with a clean retest record and, where useful, detections and runbooks so the same gap is caught next time.
