The Challenge

Why Most SIEM Deployments Fail

Over 60% of SIEM implementations underperform because organizations lack the analysts to tune rules, investigate alerts, and maintain the platform. The result is alert fatigue, missed threats, and wasted investment.

Log Collection & Correlation

  • Centralized log ingestion from firewalls, servers, endpoints, cloud platforms, and applications
  • Real-time event correlation using behavioral rules and machine learning threat models
  • Automated log normalization and enrichment for faster investigation
  • 365-day log retention for compliance audit trails and forensic analysis

Threat Detection & Response

  • 24/7 SOC analyst monitoring with human review of every critical alert
  • MITRE ATT&CK mapped detection rules updated weekly against emerging threats
  • Automated alerting with severity classification and escalation workflows
  • Incident response coordination with containment guidance and remediation support

Core Capabilities

What Our Managed SIEM Delivers

We handle the heavy lifting of SIEM deployment, tuning, and daily operations so your team receives actionable intelligence instead of raw alerts.

Continuous Rule Tuning

Our analysts continuously refine detection rules to reduce false positives and catch new attack techniques. We tune your SIEM monthly based on your environment, threat landscape, and compliance requirements. Most organizations see a 70% reduction in false positives within the first 90 days of our managed service.

Compliance Reporting

Pre-built compliance dashboards and automated reports for CMMC, HIPAA, PCI DSS, SOC 2, and NIST CSF. Our SIEM generates the audit evidence your assessors require, including access logs, change tracking, and incident documentation. Compliance reporting runs on schedule without manual effort from your team.

Threat Intelligence Integration

We integrate commercial and open-source threat intelligence feeds directly into your SIEM correlation engine. Known malicious IPs, domains, and file hashes are automatically matched against your log data. New indicators of compromise from our threat research team are deployed within hours of discovery.

Cloud & Hybrid Coverage

Native integrations with AWS CloudTrail, Azure Monitor, Google Cloud Logging, Microsoft 365, and SaaS applications. Whether your infrastructure is on-premises, cloud-native, or hybrid, our managed SIEM provides unified visibility across every environment without gaps in coverage or telemetry blind spots.


How It Works

Three Steps to Full Visibility

1

Environment Discovery

We inventory every log source across your infrastructure, identify gaps in coverage, and design the optimal collection architecture for your compliance needs.

2

Deploy & Tune

Our engineers deploy log collectors, configure parsers, build correlation rules, and run a 30-day tuning period to baseline your environment and reduce noise.

3

Monitor & Report

24/7 analysts monitor your SIEM, investigate alerts, and deliver monthly executive reports. You get a dedicated security advisor for quarterly strategy reviews.



FAQ

Managed SIEM Questions

What is the difference between SIEM and XDR?
SIEM focuses on log aggregation, event correlation, and compliance reporting across your entire IT infrastructure. XDR focuses on threat detection and automated response across specific security domains like endpoints, network, and cloud. Many organizations use both: SIEM for compliance visibility and long-term log retention, XDR for real-time threat detection and rapid response. Learn more on our managed XDR page.
How long does it take to deploy a managed SIEM?
Initial deployment typically takes 2 to 4 weeks depending on the number of log sources and complexity of your environment. We begin ingesting critical logs within the first week, complete full source onboarding by week three, and run a 30-day tuning period to optimize detection accuracy. You have 24/7 monitoring coverage from day one of log ingestion.
What log sources do you support?
We support over 500 log source types including firewalls (Palo Alto, Fortinet, Cisco), endpoints (CrowdStrike, SentinelOne, Microsoft Defender), cloud platforms (AWS, Azure, GCP), identity providers (Active Directory, Okta, Azure AD), email systems (Microsoft 365, Google Workspace), and custom applications via syslog, API, or file-based collection.
Does managed SIEM satisfy CMMC and HIPAA logging requirements?
Yes. Our managed SIEM is configured to meet the audit logging requirements of CMMC Level 2 (AU.L2-3.3.1 through AU.L2-3.3.2), HIPAA Security Rule (164.312(b)), PCI DSS Requirement 10, and SOC 2 CC7.2. We provide pre-built compliance reports and retain logs for the required periods. See our CMMC managed IT and HIPAA managed IT pages for framework-specific details.
What happens when a threat is detected?
When our SIEM correlation engine identifies a potential threat, a SOC analyst investigates within minutes. Confirmed threats trigger our incident response process: immediate containment actions, notification to your designated contacts, and guided remediation steps. Critical incidents receive phone notification within 15 minutes. All incidents are documented with full forensic timelines for your records and compliance evidence.
