SIEM Implementation and Migration
Veyzer's SIEM Implementation and Migration services helps organizations to stay ahead of potential security risks. A robust Security Information and Event Management (SIEM) system is crucial for comprehensive monitoring, threat detection, and incident response. As a Splunk and Microsoft authorized partners, our SIEM Implementation and Migration Services ensure that your organization is equipped with a tailored, efficient, and scalable SIEM solution to protect against emerging threats.
SIEM Implementation
We provide complete journey to automation, orchestration, integration and response.
Identify security- goals Compliance (e.g., HIPAA, PCI-DSS),
Evaluate SIEM options
We create custom integrations between different systems, tools, components, API's. Allowing you to connect and coordinate all of your activities.
Prepare infrastrucutre and data
We specialize in developing custom playbooks. They consist of structured blocks of workflows which are readable, repeatable and manageable.
Deployment and configuration
We provide full workflow automation from A-Z. Freeing you from the time-consuming repetitive task and enabling you to focus on critical and higher impact assignments.
Training and operationalization
We provide full workflow automation from A-Z. Freeing you from the time-consuming repetitive task and enabling you to focus on critical and higher impact assignments.
Monitoring and tuning

Requirements
Identify security goals: Compliance (e.g., HIPAA, PCI-DSS), threat detection, forensic investigations, incident response, etc.
Inventory of IT assets: Catalog systems, networks, and applications to monitor.
Define scope: Determine the volume of logs, the type of events you need to monitor, and key performance metrics.
Evaluate SIEM options
Cloud-based vs. On-premise: Decide based on scalability, cost, and control. Cloud-based: Easier scaling (Microsoft Sentinel). On-premise: High control over the infrastructure (e.g., Splunk Enterprise). Vendor selection: Compare top SIEM solutions based on features like: Log collection and correlation capabilities. Integration with existing security tools. Threat intelligence and alerting features. Compliance reporting. User interface for real-time monitoring and investigation. Costs: Look at licensing costs (pay-per-volume vs. flat-rate licensing).
Prepare infrastrucutre and data
Network and System Integration: Ensure that network devices, servers, firewalls, databases, and security tools can send logs to the SIEM. Establish Log Sources: Prioritize critical logs (firewalls, antivirus, IDS/IPS, etc.). Standardize log formats to ensure compatibility. Ensure time synchronization (NTP) across all log sources for accurate correlation. Define Event Correlation Rules: Identify common attack patterns and define rules that trigger alerts.
Deployment and configuration
Agent Deployment: Install necessary agents on the servers or configure devices to forward logs via syslog, SNMP, or API. Configure Data Collection: Set up log ingestion based on your needs (real-time or batch processing). Create Dashboards: Customize dashboards to visualize key security metrics like event types, source IPs, and user activities. Set Up Alerts: Define thresholds for suspicious activity (e.g., multiple failed login attempts). Tune the SIEM to minimize false positives. Test and Optimize: Test correlation rules using common attack scenarios (e.g., brute force, phishing). Review false positives and refine rules accordingly.
Training and operationalization
Train SOC analysts: Train the team on SIEM functionalities, custom rules, and dashboard usage. Incident Response Workflow: Define incident response procedures based on SIEM alerts. 24/7 Monitoring Setup: For large environments, establish a 24/7 monitoring system for real-time response.
Monitoring and tuning
Daily Log Reviews: Analysts review and act on alerts. Tuning: Refine the SIEM as new threats emerge and adjust correlation rules to optimize performance. Audit and Compliance: Regularly audit logs for compliance and security hygiene.
SIEM Migration
We can help migrate you SIEM solution from On-Premise to Hybrid or Cloud.
We can help you move from one vendor to Splunk or Microsoft Sentinel
Migration Strategy
We decide on a migration strategy. Whether it would be a migration from an on-premise, hybrid, or cloud model or transitioning between different SIEM vendors.
Assesment of current SIEM
We conduct an assessment of your current SIEM environment, including all data sources, log retentions policies, integrations, searches, alerts, visualizations, ensuring nothing will be missed
Migration and transition
Depending the type of migration we agree, we configure new data sources, migrate all existing configuration , dasbhoards, and alerting rules. We test and validate the new service. We recommend running parallel operation of both systems for a period of time to ensure no data loss.
Decomissioning
We move historical data to ensure the new SIEM service will have access to it and backup the existing data. We gradually decomissioning the old SIEM service planning a smooth handover, providing training to guarantee operational readiness.
