Cyber advisory for regulated businesses in Singapore

We find what a regulator or attacker would see in your business. Then we fix it.

Hands-on cyber reviews for clinics, law firms and professional services businesses in Singapore. No jargon, no checklists — a clear picture of where you're exposed, what matters most, and what to do next.

With legal oversight built in — so what we find and fix stands up when a regulator, client or lawyer looks closely.

How clients come to us
Planned work
I need to know where I stand

A review, a remediation, a vendor contract, a questionnaire to answer, a deal to close. Something specific needs looking at properly.

I need someone in my corner

A DPO, a privacy retainer, a fractional CISO. Someone who already knows the business when pressure arrives.

Urgent
Something has happened or is about to

A breach, a ransomware attack, a regulator on the phone. Legal and cyber advisory in the room from the first hour.

Who we work with

Built for businesses that handle sensitive data.

Different industries trigger different kinds of scrutiny. We frame the work around the questions your patients, clients, buyers and regulators are already asking.

Industry view

A patient data breach could end your practice. Are you ready for scrutiny?

Clinics and health providers handle some of the most sensitive data there is. One breach or complaint can trigger regulatory investigation and destroy patient trust overnight.

Review of how patient data is stored, accessed and shared
AI exposure checked — patient data in ChatGPT identified
PDPA & MOH readiness strengthened

"We didn't realise how exposed we were until someone actually looked."

Why it matters
The same offer, framed for the scrutiny your buyers actually apply.
How it works

From first call to full clarity.

01

We talk

A confidential conversation about what triggered your concern. No obligation — we’ll tell you if we can help and what it would involve.

02

We look

A hands-on review of your actual systems, data, access, vendors and AI tool usage. We look at what’s really there — not what a policy says should be.

03

We tell you

A plain-English report of what we found, how serious it is, and what to fix first. Structured with legal awareness so it holds up later.

04

We fix it

If you want us to lead the remediation, we do. If you want ongoing advisory, we’re there. You leave the engagement materially more defensible.

Why Sentra

Legal oversight built in — not bolted on after.

When the stakes are high, how findings are documented, handled and communicated matters as much as the findings themselves.

Engagements can be structured with legal oversight so sensitive discoveries are treated with the care they deserve from day one. That’s what separates a Sentra review from a standard cyber assessment.

Findings handled with legal awareness

What you document and how you frame it can affect your legal position later. We treat this seriously from the start.

Priority and accountability are clear

Specific guidance on what to fix, in what order, and how to communicate the actions you’ve taken.

Output that holds up

When a regulator, client or external counsel examines what you did and why — it stands up. That’s the point.

Diagnostic

See where you stand in two minutes.

Eight plain-English questions. No technical knowledge needed. We’ll show you where your real exposure sits.

From the founder
"Most businesses have never had someone actually look at what's there. That's the gap I built Sentra to close."

I’ve spent years seeing how audits, incidents and regulatory reviews actually unfold. The problem is rarely that businesses don’t care — it’s that no one has ever looked properly and told leadership honestly what they’d find.
