ABOUT
Senior expertise. Direct access.
I'm Ove.
Over three decades I've worked in IT and Security at Cisco, NatWest, JP Morgan, 10X Banking, Santander, Schlumberger and many others, and I now am/run "Immaginare" directly. I have no commercial partners to "influence" my work. And I have no products to sell except for my own expertise.
Recently I was security architect for two of Cisco's production AI/LLM products: AI Defense, including controls around prompts, PII and sensitive data, and the Webex Contact Center transcription and sentiment-analysis pipeline.
For much of the last decade my focus has been Cloud Security and DevSecOps: putting security into architecture, infrastructure and development pipelines
Immaginare is deliberately small. The person you speak to is the person who does the work. There is no account manager, no hand-off to a junior consultant and no large consultancy team to support. No cost markups or surprises.

SERVICES
Where I can help.
Here are three sample focused engagements: an AWS Security Review, an AWS Security Architecture Review, and private or air-gapped AI installation.
Cloud security architecture
Design and review of secure cloud architectures, with the deepest experience in AWS, most native AWS security services, worked with directly.
Got 30 AWS accounts that are a mess? I have worked with that.
Solid Azure experience and working GCP knowledge, used to multi-cloud environments.
Risk assessment & audit
Practical, evidence-based risk assessments and audits - not a tick-box exercise. CISA-certified and an ISO 27001:2013 Lead Auditor, with implementer credentials in ISO 22301 and PCI-DSS for when the standard itself needs building, not just checking.
M&A integration security
Identifying and mitigating the security risk that comes with acquisitions - from due diligence through to integrating an acquired company's systems and controls into the parent. Hands-on with a number of Cisco's acquisitions, including Pirelli Optics and Tandberg.
DevSecOps & AI/LLM security
Building security into the development pipeline itself - build tooling, CI/CD, infrastructure as code - plus recent hands-on architecture work securing production LLM systems: prompt-layer guardrails, PII/DLP filtering, and sentiment-analysis pipelines.
TRACK RECORD
Large corporations. Small ones. Some very, very small ones.
I've worked inside global technology companies, banks, investment firms, energy businesses and start-ups. That range matters: security that works for a global bank isn't necessarily the right answer for a twenty-person technology company.
Acquisition integration work has included several of Cisco's M&A deals — among them Pirelli Optics and Tandberg — identifying and closing the security gaps that come with folding one company's infrastructure into another's.
