01
Virtual CIO
Ongoing technology leadership for organisations that need senior technical judgement without a full-time CIO. Roadmaps, vendors, operating rhythm, risk translation and executive decision support.
Technical advisory practice
Virtual CIO, cybersecurity, AI and crypto infrastructure advisory.
Independent technical judgement for organisations making decisions where systems, security, automation and trust matter.
For boards, founders, executives and operators who need a calm technical view before committing to vendors, platforms, security programs, AI systems or digital asset infrastructure.
Led by Christo. Supported by a private technical network where required.
Four lanes. One judgement layer.
christo.io works across technical areas where decisions carry commercial, operational, security or trust consequences.
02
Cybersecurity
Threat detection, proactive penetration testing under authorised scope, cybersecurity management advice and practical projects to defend and protect business assets. No theatre, no fear-selling, no unauthorised testing.
03
AI advisory
Practical AI adoption, workflow automation, governance and internal tool design. The focus is useful systems, safe data handling and operational fit.
04
Crypto infrastructure
Advice on wallets, custody, controls, attestations, audit readiness and the operational risks around digital asset systems.
Engagement models
Retained, scoped or decision-specific.
Some clients need ongoing virtual CIO support. Others need a focused review before a board decision, vendor commitment, AI rollout, security program or digital asset infrastructure change.
- Virtual CIO retainer.
- Fixed-scope technical review.
- Cybersecurity posture or authorised assessment pathway.
- AI adoption and governance review.
- Board or executive briefing.
- Crypto and digital asset control review.
Example client contexts
Where the work tends to sit.
- Financial services providers, fintechs, funds, banks and regulated operators.
- Defence and government organisations where security, procurement and technical assurance matter.
- Universities and research-linked ventures moving deep technology toward operational use.
- Investors and family offices assessing technology, cybersecurity, AI or digital asset exposure before committing capital.
- Private operators that need specialist capability brought in under controlled scope, without turning the work into a public performance.
Built for serious operators.
christo.io is suited to organisations that already know technology matters, but need a clearer independent view before acting.
Deep-tech and technology companies
When the product, infrastructure or security posture needs executive-level technical judgement.
Boards and executives
When a technology decision needs to be translated into risk, cost, timing and consequence.
Professional services firms
When client-facing advice depends on understanding systems, evidence, controls or AI capability.
Government-facing organisations
When cybersecurity, procurement, assurance or implementation risk needs a sober technical read.
Crypto and digital asset operators
When wallets, custody, controls, attestations or operational evidence need to stand up to scrutiny.
Founders moving from prototype to operations
When early technology has to become reliable enough for customers, partners, funders or regulators.
Access model
Request a secure channel before sensitive detail is exchanged.
New matters start with a secure-channel request. Share only enough non-confidential context to determine fit. If appropriate, the matter moves to the right channel: secure portal, Signal, WhatsApp or direct advisory engagement.
Verify
A one-time code confirms a real requester and filters noise.
Screen
Share only non-confidential context: matter type, urgency, organisation and the decision or risk at hand.
Open channel
If appropriate, the matter moves to a secure portal, Signal, WhatsApp or direct advisory engagement.
Operating reach
Centred in Australia. Connected into selected technical corridors.
Melbourne is the operating base. The work reaches selectively into South-East Asia, Hong Kong and Europe, including Greece, where trusted relationships and technical context matter.
