DTN Advisory is a Singapore-based cybersecurity advisory firm founded by Daniel Tinsley. We deliver intelligence-led advisory that accelerates decision velocity across ASEAN and Asia-Pacific. Our services include Fractional CISO, AI governance, threat intelligence, fusion centre design and security strategy from real-world practitioners with over 20 years of frontline experience. We operate on the end-user side, not the vendor side, bringing practical expertise built through actual operational leadership.

Why DTN Advisory

Three Principles. Real Impact.

Decision Velocity

Speed matters in security. You need people who can assess threats, define options and move to execution faster than the threat landscape changes. 90-day cycles, not multi-year programmes.

Operational Resilience

You need practitioners who have actually sat in the chair. No theory. Our advice is built on real-world decisions made under pressure, not vendor marketing or academic frameworks.

Technology That Works

AI is reshaping security. We're native to that world, not adapting legacy frameworks. Our platforms and governance approach are built for how threats and organisations actually operate today.

How We Engage

How We Work. What Makes Us Different.

The person you brief is the person who does the work. Every engagement is scoped to your situation, not pulled from a template.

90-Day Cycles

Not multi-year transformation programmes that are obsolete before they land. We work in short, focused cycles with clear decision gates and measurable outcomes at every stage.

Direct Access

You work directly with senior practitioners who have held the roles you are hiring for. No account managers, no junior analysts, no handoffs.

Vendor Independent

No product affiliations, no referral fees, no hidden agendas. Our advice is based on what you actually need, not what we need to sell.

Digital Resilience

Security that enables transformation, not blocks it. We build digital resilience into your operating model so you can adopt new technology, enter new markets and scale with confidence.

Operational Resilience

When disruption hits, your ability to maintain critical operations defines your survival. We design, test and embed resilience frameworks that work under real pressure, not just in tabletop exercises.

Built by Operators, Not Observers

Every associate in our model has operated the function they advise on. We do not deploy consultants who have only observed from the outside. If someone advises you on incident response, they have run incidents. If they advise on fusion centres, they have built them.
