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
Nessus at a glance
Nessus is a vulnerability assessment product from Tenable. It scans operating systems, network devices, applications, cloud resources and security configurations for weaknesses. The platform combines credentialed checks, remote tests and plugin-based detection to produce findings that security teams can investigate and remediate.
Core assessment work
Nessus specialists configure scan policies, select suitable plugins and control scan scope to reduce disruption. They review evidence behind each finding rather than treating every alert as equally urgent. Their work can cover internal networks, perimeter systems, web services, virtual environments and endpoint infrastructure.
- Build authenticated and unauthenticated scan policies
- Validate vulnerabilities and false positives
- Map findings to affected assets and owners
- Prepare remediation-focused reports
Ecosystem and tooling
Nessus operates within the wider Tenable ecosystem and is commonly used alongside Tenable Security Center, Tenable.io and Tenable Vulnerability Management. Strong specialists understand plugin updates, asset discovery, scan scheduling, credentials, exclusions and exports. They also work with CVE references, CVSS context, ticketing systems and security information workflows.
When expertise matters
Companies bring in freelance Nessus professionals when a scan program needs a reliable setup, an independent review or faster remediation. Typical triggers include infrastructure changes, compliance preparation, a new cloud environment or persistent findings that internal teams cannot explain. In Germany, remote delivery often works well, while regulated environments may require on-site workshops and German-language reporting.
Project deliverables
A Nessus engagement should produce more than a scan file. Depending on scope, the specialist may deliver a tested scan strategy, asset inventory, exception register, risk-based findings report, remediation backlog and executive summary. They can also define recurring assessment processes and handover documentation for internal security teams.
Signs of strong specialists
Experienced Nessus professionals distinguish exposure from evidence and explain technical risk in language that system owners can act on. They protect credentials, manage scan impact and document assumptions. Look for people who can connect findings with patching, hardening, identity controls, network segmentation and cloud security rather than treating Nessus as an isolated tool.
- Calibrate scans to the environment and business risk
- Reproduce important findings before escalation
- Separate accepted risk from unresolved risk
- Communicate clearly with technical and non-technical stakeholders
Frequently asked questions
Key details about Nessus, drawn from the questions we get asked most.
Nessus is used to identify vulnerabilities, insecure configurations and missing security updates across infrastructure and connected systems. It helps teams prioritize remediation by providing evidence, severity context and affected asset details.
Nessus is often considered when a company wants broad plugin coverage, flexible scan policies and detailed validation workflows. Qualys may suit organizations seeking a wider cloud-based asset and compliance suite, while OpenVAS can be attractive where open-source tooling and control over the deployment are priorities.
A strong Nessus specialist usually understands network protocols, operating system hardening, patch management and identity controls. Experience with Tenable Security Center, Tenable.io, cloud environments, ticketing workflows and risk reporting can make the assessment more useful.
The right Nessus experience depends on scope, asset complexity and the quality of existing security processes. A focused scan review may need a narrowly focused specialist, while a new vulnerability management program calls for someone who can design policies, validate findings, establish ownership and guide remediation.
Nessus projects can often be delivered remotely when secure access, asset information and communication channels are available. On-site work may be useful for sensitive networks, workshops or environments with strict access rules, and German-language documentation can matter for local stakeholders.
A quality Nessus assessment explains scope, credentials, exclusions, scan impact and evidence for important findings. The specialist should separate false positives from confirmed exposure, connect issues to responsible owners and provide remediation steps that can be verified.
Tenable Nessus Professional is a Nessus edition commonly used for vulnerability assessment by security teams and service providers. It can suit organizations that need hands-on scanning and reporting, while larger environments may require broader Tenable capabilities for centralized asset management and continuous operations.
Nessus findings can be exported or connected to workflows for ticketing, remediation tracking and management reporting. A capable specialist can map findings to asset owners, define exceptions, reduce duplicate work and establish checks that confirm whether weaknesses were actually resolved.
The average hourly rate of freelancers in Germany who have used Nessus in their recent projects is 99 €, which corresponds to a daily rate of about 792 € based on an 8-hour working day.
