Enrique Gallardo
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
Vulnerability scanning
Nessus is used to find security weaknesses across hosts, services, and devices before attackers do. Strong specialists know how to scope scans, pick safe plugins, and read the results in context, not just export a report.
What teams use it for
- Internal and external vulnerability checks
- Configuration review and hardening work
- Compliance evidence and audit support
- Patch validation after changes
It is common in enterprises, managed services, and regulated environments where repeatable scanning matters.
Tenable ecosystem
Nessus sits in the Tenable family, so experts often work with Tenable.io, Tenable.sc, and asset inventories around it. They also know how to manage credentials, scan templates, exclusions, and scheduling without creating noise or outages.
Skills that matter
Good specialists understand operating systems, network protocols, authentication, and common exposure patterns. They can separate real risk from false positives, explain CVEs in plain language, and map findings to action for security and infrastructure teams.
When to bring in help
Companies usually bring in freelance expertise when scans are failing, coverage is incomplete, or findings need cleanup before an audit. In Germany, this often happens in mixed-language teams where reporting must be clear for local staff and global security owners.
Strong delivery
A solid professional does more than run Nessus Professional or Tenable Nessus. They document scan scope, set safe schedules, improve repeatability, and help teams build a process they can keep using after the project ends.
Frequently asked questions
Key details about Nessus, drawn from the questions we get asked most.
Nessus is used to scan systems for known vulnerabilities, weak settings, missing patches, and exposed services. Teams use it to get a clear view of technical risk across servers, endpoints, network gear, and cloud-connected assets. The real value comes when the findings are turned into remediation work, not just stored in a report.
Nessus is often chosen for broad plugin coverage, straightforward setup, and flexible scan policies. Compared with larger Tenable setups, it is the scanning engine that many teams start with before moving into Tenable.io or Tenable.sc for centralized management. The best choice depends on whether you need a standalone scanner or a wider vulnerability program.
A strong Nessus specialist should understand Windows and Linux basics, TCP/IP, authentication methods, and common server services. They should also be comfortable with patching workflows, ticketing systems, and reading CVE details. That mix helps them reduce false positives and produce useful remediation guidance.
Nessus work can be simple when you only need basic scan setup, but it becomes more demanding when scope, credentials, and reporting matter. Projects usually need someone who has handled scan tuning, safe exclusions, and result review. If the findings will support audit or compliance work, the bar is higher because the output must be clean and repeatable.
Yes, Nessus work is often done remotely because scan design, result review, and reporting do not require a constant on-site presence. On-site help can still be useful for network access checks, sensitive environments, or first-time rollout. In Germany, companies often want clear communication in English, and sometimes German for local stakeholders.
A trustworthy Nessus report has a clear scope, credentials where needed, and settings that avoid unnecessary noise. Good specialists explain which findings are confirmed, which are contextual, and which need manual verification. They also show how the scan aligns with the real environment, not just with default templates.
Yes, Nessus is commonly referred to as Tenable Nessus, and the paid edition is often called Nessus Professional. Searchers use these names interchangeably in many buying and hiring conversations. A good expert should know the differences in licensing, scan features, and how each fits into a wider Tenable setup.
Look for someone who asks about scope, assets, credentials, and the purpose of the scan before starting. A strong Nessus freelancer can explain plugin choices, false positives, safe scheduling, and how the results will be handed over. Quality shows in clear documentation, practical remediation advice, and a process your team can repeat.
The average hourly rate of freelancers in Germany who have used Nessus in their recent projects is 100 €, which corresponds to a daily rate of about 797 € based on an 8-hour working day.
