SIEM

Security monitoring and managed detection

Almost every organization we assess is already generating the logs that would have caught the breach. They are sitting in a firewall buffer that overwrites every six hours, or in a cloud tenant with a 30-day retention nobody configured. Detection is rarely a data problem. It is a correlation and attention problem.

This is what monitoring looks like from your side.

Read-only access for your team, the same view our analysts work from. Every alert carries the evidence that triggered it and the actions we took — so you are auditing our work, not taking it on trust.

Scope of work

What is included.

Right for you if you have more than roughly 50 endpoints, any internet-facing service, or a compliance requirement to retain and review security logs.

  • Log pipeline engineeringCollection from firewalls, endpoints, domain controllers, cloud tenants, databases, VPN concentrators and applications — normalized, timestamped and stored with tamper-evident retention.
  • Detection engineeringCorrelation rules mapped to MITRE ATT&CK techniques and tuned to your environment, so the alerts that fire are the ones that mean something.
  • 24/7 monitored SOCAnalyst coverage around the clock, with defined acknowledgement and escalation times per severity and a named account lead who knows your estate.
  • Triage and responseAlert validation, containment actions taken under a pre-agreed playbook, and a written incident record for every escalation.
  • Compliance reportingRetention, review evidence and audit trails aligned to ISO 27001, SOC 2 and PCI DSS logging requirements — produced monthly, not scrambled together the week before an audit.
  • Threat huntingMonthly hypothesis-driven hunts across historical data for activity that never triggered a rule.
Engagement sequence

Four phases, in this order.

The order matters more than the speed. Every phase has an exit condition you sign off before the next one starts.

Source inventory

We identify every device and service that produces security-relevant logs, and confirm what is currently retained versus silently discarded.

Onboard and normalize

Collectors deployed, parsing validated, time synchronized. We prove end to end that a test event reaches the platform and is searchable.

Tune to a workable signal

Baseline for two to four weeks, suppress the noise your environment generates legitimately, and publish the detection catalog for your approval.

Monitor and improve

Live monitoring with monthly rule review, coverage gap analysis against ATT&CK and a quarterly detection maturity report.

Deliverables

What you receive.

  • Documented log source inventory and coverage map
  • Detection catalog mapped to MITRE ATT&CK
  • Response playbooks per alert class
  • Monthly SOC report: alerts, incidents, response times
  • Audit-ready log retention evidence
Tools & standards

What we work with.

  • Microsoft Sentinel

Vendor position

We hold no exclusive reseller obligations. Recommendations are made on fit, your team's capacity to operate the thing, and local support availability — in that order.

Questions

SIEM, specifically.

Do we have to buy an expensive platform?

No. We deploy on Wazuh or Elastic where budget is the constraint, and on Microsoft Sentinel where you already hold the Microsoft licensing that makes it cheap. The engineering matters far more than the badge on the console.

What actually happens when something fires at 2am?

An analyst validates it within the acknowledgement window for that severity. If it matches a pre-approved containment playbook — isolate host, disable account, block address — we act immediately and tell you. If it does not, we call your escalation contact. You get a written record either way.

How much log volume is this?

For a 200-endpoint environment, typically 15–40 GB a day depending on how verbose your firewall is. We size and filter at the collector so you are not paying to ingest routine noise.
