Case Studies
Representative scenarios that show how we approach the work when the system on the line is one an institution cannot afford to lose.
The following are representative engagement scenarios, composites that illustrate our approach to high-stakes work and the outcomes we target, not reports of specific named clients. They show how we think about the problem and what we set out to achieve.
Financial Sector Cybersecurity Transformation
Sector: Banking & Financial Services
Client: Major regional bank (anonymous)
Challenge
A bank carrying aging security infrastructure and ISO 27001 gaps, facing rising fraud and intrusion attempts while BNA supervision sets a rising bar: the kind of exposure where a single breach reaches the balance sheet and the customer trust the franchise runs on.
Solution
A comprehensive cybersecurity program that starts with an honest security-posture assessment and ISO 27001 gap analysis, then closes the gaps: zero-trust network segmentation, SIEM deployment, IAM/PAM, encryption frameworks, incident-response playbooks, and the compliance documentation BNA scrutiny demands, each decision owned by a senior engineer.
Results
- ✓Substantially reduced overall security risk score
- ✓Positioned for ISO 27001 certification
- ✓Strengthened defenses against security breaches
- ✓Aligned to BNA security expectations
- ✓Materially faster incident response
- ✓Materially reduced fraud exposure
Government Infrastructure Modernization
Sector: Government & Public Sector
Client: National government ministry (anonymous)
Challenge
A ministry running on legacy on-premise infrastructure with unreliable availability, no disaster recovery, and recurring service disruptions citizens feel directly, all while holding citizen data whose sovereignty and protection are non-negotiable.
Solution
A digital transformation that modernizes without surrendering control: hybrid cloud migration (AWS + on-prem), zero-trust network architecture, high-availability design, multi-region disaster recovery, a secure citizen portal, identity management, and backup automation, with Lei n.º 22/11 alignment and data sovereignty designed in from the start.
Results
- ✓Targeted high-availability uptime
- ✓Significant performance improvement
- ✓Tested disaster recovery with rapid recovery objectives
- ✓Citizen services designed for 24/7 availability
- ✓Meaningful reduction in total cost of ownership
- ✓Reference model for national digital strategy
Energy Sector OT Security
Sector: Oil, Gas & Energy
Client: Energy production facility (anonymous)
Challenge
A production facility where SCADA/ICS systems sit exposed, with no IT/OT segmentation and aging control equipment in a safety-critical environment: the scenario where a breach is not downtime but a danger to people and the plant itself.
Solution
An OT security program built around the safety stakes: OT asset inventory, ICS threat modeling, combined safety-and-security risk assessment, Purdue Model segmentation, industrial firewalls, ICS monitoring, secure remote access, and backup & recovery, closing the path from the corporate network to the systems that keep operations safe.
Results
- ✓OT and IT environments segmented
- ✓Designed to protect safety-critical operations
- ✓Substantially reduced the attack surface
- ✓Remote access secured (MFA + logging)
- ✓Improved visibility into the OT network
- ✓Alignment with industry standards
