Case studies

Seven engagements from our cybersecurity and virtual CISO (A fractional chief information security officer. Security leadership as a service. A virtual CISO sets your security direction, puts it in place with your team, and reports on it to management.) work, for clients in finance, technology and other sectors. They cover VAPT (Vulnerability assessment and penetration testing. Finding the weak spots in apps, APIs, networks and cloud, and testing them the way an attacker would.), GRC (Governance, risk and compliance. Security policies, the review of risks, and meeting the rules and standards that apply to you.), ethical hacking (Attacking a system with the owner's permission, to find weaknesses before a real attacker does.), compliance, risk assessment and security tools.

A stack of three engagement reports, each tagged with how long the work ran and with its sector: finance, real estate or technology

The seven cases

Clients are not named. Durations are as of September 2026.

We have also carried out security risk assessments for clients in retail, real estate, finance and space, and for many product companies.

Case study 1

Custom VAPT and a risk plan

Vulnerability assessment and penetration testing designed for the client. Then a plan to reduce the risk, and the work to carry it out.

What we did

  • Testing in several rounds, each deeper than the last
  • After every round, we worked directly with the client's developers to fix the issues
  • The tests covered API (Application programming interface. The interface one program uses to talk to another.) security, payment security, infrastructure security, data storage and retrieval, and secure coding practices
Testing in three rounds shown as three rings around a target, each round going deeper, and after each round an arrow to the developers, who fix what was found
