SIEM, EDR & Security Monitoring

SIEM design, deployment and tuning

We plan the log sources that matter, size the platform properly, and build correlation rules mapped to MITRE ATT&CK — so coverage is measurable rather than assumed.

• Log source onboarding: firewalls, endpoints, directory services, cloud, databases and business applications.
• Normalisation and parsing so events from different vendors correlate correctly.
• Use-case development mapped to ATT&CK tactics, with documented detection logic and expected response.
• Alert tuning to cut false positives and stop analyst fatigue before it starts.
• Dashboards and reporting for SOC analysts, IT leadership and auditors.

EDR and endpoint response

Endpoint detection and response gives you the visibility and the kill switch. We roll it out cleanly across the estate, configure policies that block without breaking business processes, and integrate telemetry back into the SIEM.

• Phased EDR/XDR rollout with pilot groups, policy hardening and exclusion management.
• Endpoint isolation, process termination and rollback procedures documented and tested.
• Integration of endpoint telemetry with SIEM correlation and threat intelligence feeds.
• Ivanti-based endpoint management, patch orchestration and configuration compliance.

Monitoring, hunting and incident response

Detection without response is an expensive alarm. We define who does what at 3am, rehearse it, and hunt proactively for the activity that never triggered a rule in the first place.

• Continuous monitoring with agreed triage and escalation SLAs.
• Hypothesis-driven threat hunting across endpoint, identity and network telemetry.
• Incident response playbooks for ransomware, business email compromise, insider misuse and data exfiltration.
• Digital forensics support using Autopsy and Cellebrite-grade tooling for evidence handling.
• Post-incident review with detection gaps fed straight back into the SIEM rule set.

Data protection and email security

Monitoring extends beyond endpoints. Our engineers deploy and administer data loss prevention, email security and web gateway platforms — Symantec DLP, Forcepoint DLP and Email Security, Proofpoint, Symantec ProxySG and Data Center Security — so sensitive data is watched wherever it moves.
