Security Findings Kimberly Helped Reduce
Risks Reduced
Finding
Security introduced too late in SDLC
- Action
- Embedded secure SDLC practices, engineering guardrails, and earlier security testing.
- Impact
- Improved visibility and earlier remediation of application and infrastructure risk.
Finding
Vulnerability management lacked business-risk prioritisation
- Action
- Introduced risk-based remediation using exploitability, business impact, and delivery context.
- Impact
- Helped teams focus remediation on the risks that mattered most.
Finding
CI/CD pipelines needed stronger security controls
- Action
- Integrated security controls and tooling into build and release workflows.
- Impact
- Improved detection of vulnerabilities, misconfigurations, and dependency risk earlier in delivery.
Finding
Security culture needed scale
- Action
- Supported security champions, developer enablement, mentoring, and practical engagement with engineering teams.
- Impact
- Increased distributed security ownership.
Finding
Regulatory expectations needed operationalisation
- Action
- Developed policies, standards, governance controls, and regulatory alignment support.
- Impact
- Helped organisations translate compliance expectations into practical security controls.
Finding
Complex technical risk needed clearer business communication
- Action
- Translated technical findings into pragmatic remediation plans and executive-level risk decisions.
- Impact
- Improved stakeholder alignment and prioritisation.
Security Philosophy
True North
- Security should be measurable, developer-centric, and focused on exploitability rather than compliance theatre, vanity metrics, or checkbox exercises.
- Security should be something teams can use, own, and scale.
- Security can be a growth enabler, not just a control function.
Role Alignment
Good Missions for Me
- Build Product Security or PSIRT from the ground up
- Turn vulnerability noise into exploitable-risk reduction
- Make secure-by-design practical across SDLC, cloud, and CI/CD
- Translate DORA, NIS2, CRA, ISO 27001, and ISO 42001 into low-friction controls
- Help security and engineering teams work together without gridlock
- Support strategy, advisory, mentoring, workshops, panels, and conference talks
