Last position:
Fractional CTO at OpsWorker
OpsWorker turns Kubernetes alerts into root-cause analyses, on top of the monitoring a team already runs. I lead the technical side: the agent architecture, the AWS infrastructure it runs on (fully inside EU regions), and the engineering decisions behind it, read-only in the cluster by default, human in the loop for judgment. The stack underneath: Amazon Bedrock and Bedrock AgentCore, agents built with the Strands Agents SDK, the Claude and OpenAI APIs, and the Kubernetes API.
Enrique G.
Last position:
Security Architect at Capgemini
I implemented a Zero-Trust architecture for robust, military-grade maritime container mini data centers based on VMware & Tanzu to support containerized GIS workloads for ground forces. The main focus was on securing communications, workload protection, and data access in contested electronic battle environments affected by jamming, interception, signal manipulation, and constantly changing operational conditions. I designed and architected use cases so that every element of workload, identity, and system could continue to operate independently and securely even in degraded or disrupted scenarios. In parallel, I defined the enterprise and solution security architecture with LeanIX, Bizzdesign, and HOPEX as enterprise architecture, repository, and governance platforms to maintain architecture inventory, relationships, traceability, target pictures, and security governance in complex environments. For the architectural designs, I used Sparx Enterprise Architect to describe formal architecture views, interfaces, trust boundaries, and system architecture in both IT and OT environments. IriusRisk was used for threat modeling of the solution to identify architecture-driven risks, derive security requirements, and detect countermeasures and design gaps directly from the solution models. Risk and compliance management was supported with Archer. Architecture decisions, control gaps, and operational risks were translated into controlled governance and auditable compliance measures. For documentation, collaboration, and visual design, I used Confluence to maintain Architecture Decision Records, Security Blueprints, and workflows. I used Lucidchart and draw.io to create design artifacts tailored to stakeholders. I also defined OT security concepts with support from electrical and mechanical engineers in the areas of oil, vehicle onboard systems, rail, power plants, pharma, gas turbines, and nuclear technology. I created the end-to-end OT security strategy, starting with global policy, developed into standards and procedures, and finally aligned with Bell-LaPadula, Purdue Model, SABSA, TOGAF ADM, CENELEC 50701, IEC 62443, and NIST standards. In addition, I worked with engineering team leads to identify critical KBP assets and place them under protective measures that segmented SCADA, PLC, and HMI assets. I drove collaboration between Security, IT, and OT teams to create standardized workflows and use cases for the OT security solution catalog, while integrating Defense-in-Depth and Zero-Trust principles into operational environments. A key part of my work was integrating multidisciplinary engineering, security, and operations stakeholders into a unified security blueprinting strategy and ensuring that architecture, threat modeling, governance, and documentation were technically strong and operationally practical.

About the technology
What SIEM does
SIEM, short for Security Information and Event Management, collects and correlates security events from infrastructure, applications, endpoints, identities and cloud services. It helps security teams detect suspicious activity, investigate incidents and preserve an auditable record of what happened. A well-designed SIEM turns scattered logs into useful security signals without replacing sound operational processes.
Core use cases
SIEM supports security monitoring across hybrid environments and gives teams a shared view of activity that may indicate compromise.
- Centralize logs from servers, networks, endpoints, applications and cloud services
- Correlate events to identify suspicious behavior and attack paths
- Create alerts, investigation views and incident response workflows
- Support threat hunting, compliance evidence and forensic analysis
Ecosystem and tooling
Common SIEM environments include Splunk, Microsoft Sentinel, IBM QRadar, Elastic Security and Google Security Operations. Specialists work with agents, collectors, APIs, data pipelines and query languages such as SPL, KQL, AQL or the Elastic Query DSL. They also connect identity systems, endpoint protection, vulnerability tools, ticketing systems and SOAR automation.
When companies need specialists
Freelance expertise is useful when a SIEM rollout is delayed by unclear requirements, noisy alerts or inconsistent log quality. Companies also bring in specialists during migrations, cloud adoption, security operations improvements and audit preparation. In Germany, projects may involve distributed teams, on-site workshops or remote collaboration across several business locations, with clear communication in English or German often important.
- Define a useful event and retention strategy
- Onboard priority data sources and normalize fields
- Reduce false positives through tuned detection content
- Build dashboards, playbooks and escalation paths
Skills that matter
Strong professionals understand both the SIEM product and the systems sending data into it. They can map business risks to detections, write maintainable queries, validate alerts with realistic scenarios and explain findings to technical and non-technical stakeholders. Knowledge of identity security, cloud platforms, networking, endpoint telemetry, threat intelligence and incident response makes their work more effective.
How quality is judged
A reliable SIEM implementation produces alerts that analysts can act on, not an unmanageable stream of events. Review how the specialist handles source coverage, parsing, time synchronization, access control, testing, documentation and ongoing tuning. Ask for clear examples of detection logic, investigation workflows and measurable improvements in signal quality, while checking that recommendations match your architecture and risk profile.
Frequently asked questions
Questions about SIEM? Start with the answers below.
SIEM is used to collect and analyze security events from systems such as endpoints, networks, applications, identity services and cloud environments. It supports threat detection, incident investigation, compliance reporting and security operations by bringing related activity into one view.
SIEM focuses on broad event collection, correlation and investigation across many sources. EDR concentrates on endpoint activity, XDR correlates signals across selected security domains, and SOAR automates response actions; these tools often work together rather than serve as direct replacements.
A strong SIEM specialist usually understands log management, detection engineering, threat hunting and incident response. Useful adjacent skills include cloud security, identity and access management, endpoint protection, network analysis, scripting, threat intelligence and security automation.
The right level depends on the scope, data sources and operational maturity of the project. A focused integration or dashboard task may need a narrower specialist, while a new detection program, migration or complex incident response setup calls for someone who can design the architecture and operating model.
Many SIEM tasks can be completed remotely because configuration, query development, documentation and tuning are performed through secured access. On-site workshops may still help with discovery, stakeholder alignment or restricted environments, and teams should agree on access controls, working language and response availability in advance.
SIEM professionals commonly work with Splunk, Microsoft Sentinel, IBM QRadar, Elastic Security and Google Security Operations. The relevant choice depends on your existing cloud and infrastructure stack, licensing model, data volume, analyst workflows and required integrations.
Good SIEM work connects detections to real risks and produces alerts that analysts can investigate. Check the specialist’s approach to log coverage, parsing, query performance, false-positive reduction, testing, documentation, access control and handover rather than judging the implementation by dashboards alone.
Before starting SIEM work, clarify the product, data sources, access process, alert ownership, incident escalation and expected deliverables. It is also important to understand retention requirements, change controls, working hours, the client’s cloud and endpoint landscape, and whether the assignment covers implementation, tuning or ongoing operations.
