Our services

At VD Sentinel Advisory, we help organizations reduce exposure, strengthen network security, and make operational governance work in practice.

Our services combine technical expertise with clear workflows, practical governance, and actionable guidance tailored to your environment.

Vulnerability Management & CTEM

We help organizations build, optimize, and operationalize vulnerability management programs that improve visibility, support effective remediation, and reduce exposure over time. From governance and workflows to prioritization and CTEM initiatives, we help turn security findings into measurable action.

Vulnerability Management Organization Assessment

A structured assessment of your vulnerability management capability across governance, tooling, visibility, prioritization, ownership, and remediation workflows.

We assess:

  • Governance & workflows (ticketing, escalation, remediation timelines, RACI, bottlenecks)
  • KPIs & metrics (MTTR, SLA compliance, scanning coverage, risk acceptance tracking)
  • Scanning coverage & asset discovery
  • Platform configuration & technical setup
  • Prioritization logic & risk‑based scoring
  • Reporting workflows and dashboards

Deliverables:

  • Maturity assessment
  • Gap analysis
  • Prioritized roadmap

Risk‑Based Prioritization & Decision Support

Effective remediation requires more than CVSS scores. We help organizations establish prioritization models that combine technical risk, asset criticality, business impact, and operational realities to focus remediation efforts where they matter most.

Scanning Operations & Reporting

We design scanning and reporting processes that improve coverage, reduce manual effort, and increase consistency:

  • Scheduled scans aligned with asset groups
  • Automated vulnerability and compliance reporting
  • Dashboards tailored to executives, IT teams, and auditors

Remediation Support & Tracking

We help organizations translate vulnerability findings into remediation action through structured workflows, ownership models, remediation tracking, and continuous improvement initiatives.

Exposure Validation Workshop
Proactive Defence Through MITRE ATT&CK Scenarios

A monthly, 2‑hour tabletop exercise using your real vulnerabilities and network context to simulate attacker paths based on the MITRE ATT&CK framework. We identify exposure points, detection gaps, and prioritized remediation actions.

Value delivered:

  • Realistic threat scenarios based on your environment
  • Improved collaboration between IT, network, and security teams
  • Actionable insights to reduce exposure
  • Evidence of continuous risk assessment for ISO 27001, NIS2, and other requirements


Network Security

We help organizations design, review, and strengthen network security architectures that reduce attack surface, control access, limit lateral movement, and support resilient operations.

Firewall & IDS/IPS Assessment

We assess firewall, IDS/IPS, and perimeter security configurations to ensure that controls are effective, maintainable, and aligned with operational needs. This includes rulebase review, segmentation validation, tuning opportunities, anomaly detection improvements, and reduction of unnecessary noise.

Secure Network Architecture Design

We design and review resilient network architectures that reduce attack surface, limit lateral movement, and support secure operations, including:

  • Segmentation strategies
  • DMZ design
  • Zero-trust zones
  • Secure connectivity patterns
  •  Resilient topologies and hardening recommendations

Compliance & Audit Readiness

We map network security controls to regulatory, contractual, and industry requirements such as ISO 27001, GDPR, and NIS2, and provide documentation and evidence packages for audits, client reviews, and security assessments.

Risk Communication Through Network Insights

We use real network traffic examples, architecture findings, and control gaps to make security risks understandable for non-technical stakeholders and support better decision-making.


IT Service Delivery & Operational Governance

We help organizations strengthen IT service delivery, operational governance, and process discipline to support secure, reliable, and accountable operations.

Service Delivery Management

We support IT teams in structuring and operating effective service delivery functions, with clear roles, responsibilities, communication routines, and coordination between technical and business stakeholders.

Process Optimization — Incident, Change, Problem

We review and refine operational processes to improve consistency, reduce friction, and support reliable service delivery. Our focus is on practical workflows that help teams manage incidents, changes, problems, and recurring issues more effectively.

Operational Governance & Reporting

We help establish governance frameworks, performance indicators, and reporting routines that give leadership clear visibility into service health, risks, bottlenecks, and improvement priorities.

Documentation & Service Reviews

We create or improve service documentation, run structured service reviews, and help teams maintain a shared understanding of how services operate, who owns what, and where improvements are needed.

Quality & Performance Improvement

We identify bottlenecks, inefficiencies, recurring issues, and service risks, then provide actionable recommendations to improve stability, user satisfaction, operational resilience, and accountability.

Engagement Model - From PoV to Operational Capability

Our engagement model allows clients to start small, validate value quickly, and scale at their own pace — from a focused proof of value to a fully operational vulnerability management capability. 

Step 1 — Proof of Value (PoV)
A low-commitment, limited-scope engagement using a small number of assets to demonstrate value quickly and identify immediate improvement opportunities. 

Step 2 — Vulnerability Management Assessment
A structured evaluation of your vulnerability management capability across governance, tooling, visibility, prioritization, workflows, and remediation processes.

Step 3 — Vulnerability Management Project
We implement the improvements identified during the assessment and help establish an operational vulnerability management function. This may include:

  • Defining governance structures, roles, responsibilities, escalation paths, and decision workflows
  • Designing and documenting remediation workflows, including ticket creation, prioritization, SLA tracking, and approvals
  • Configuring and optimizing the VM platform, including connectors, authentication, asset groups, and tagging strategy
  • Building and scheduling scan jobs aligned with asset criticality and operational constraints
  • Automating reporting and notifications to reduce manual effort and improve consistency
  • Creating dashboards for executives, IT teams, security teams, and auditors
  •  Developing documentation and runbooks to support long-term operations

Step 4 — Operational Takeover
We can temporarily operate or support your vulnerability management activities while your teams focus on strategic priorities. This includes scan scheduling, reporting, prioritization, remediation tracking, continuous improvement, and knowledge transfer.
