About Logic Weave

Built to Close the Gap Nobody Else Owns.

The Founder

Why I Started Logic Weave.

I've spent 24 years in technology — large enterprise, FinTech, HealthTech, SaaS. I've sat in the room when deals fell apart over a security questionnaire. I've watched capable teams spend months on tools and policies, then still fail an audit.

Not because they didn't care. Because nobody owned the execution.

Most scaling businesses can't justify a full-time CISO — but they need someone who treats their security program like it's their own. Someone who shows up, makes decisions, and is accountable for what happens next.

That's the gap Logic Weave was built to close. Not a resourcing gap. An ownership gap.

I started Logic Weave because Australian SMBs shouldn't have to choose between moving fast and being secure. That's a false choice — and one I've spent 24 years learning how to eliminate.

"I've spent 24 years watching capable teams struggle with security — not because they didn't care, but because nobody owned the execution. That's the problem Logic Weave was built to solve."

The Problem

The Missing Piece Is Ownership.

Most security advisory firms hand you a report and leave. Logic Weave stays — and owns the outcome.

Most Advisory Firms

Advice without accountability

Gap analysis delivered, implementation left to you
40-page policy templates — yours to interpret
Recommendations without someone to own them
Engagement ends before audit day
Security stays "important, but later"
Next engagement sold when the last one stalls

Logic Weave

Execution with full accountability

One person owns the program from assessment to audit
Controls implemented — not just recommended
Decisions made, evidence built, risks managed
Present on audit day, accountable for the outcome
Program sustained after certification, not abandoned
Security embedded into how the business operates

Advice without execution is a PDF in a drawer. The only thing that moves the needle is someone who owns the result.

How We Work

Four Things That Make Logic Weave Different.

Not principles for a brochure. The actual way every engagement runs.

We own the outcome, not just the advice.

Your security program gets a single owner — someone accountable for progress, decisions, and results. Not a team of rotating consultants. Not a monthly status call. One person who treats your program like it's their own.

Your audit result is our report card.

ISO 27001 readiness in under 16 weeks. Secure AWS environment in under 4. We measure success by what you achieve — the deal you close, the audit you pass, the board question you can answer. Not by hours logged.

We work inside your business, not around it.

We embed alongside your team. Not a dashboard you log into. Real involvement in your architecture decisions, your evidence collection, and your audit day walkthrough. You always know what's done, what's next, and where you stand.

We don't stop at the certificate.

Most firms exit after phase one. We build your program, then sustain it, then embed security into how the business operates — from your first audit to your board reporting to your engineering culture. That's the full journey.

Credentials

What 24 Years Buys You.

Certifications are a baseline. What matters is what they represent — and how they translate into outcomes for your business.

CISM

Certified Information Security Manager

Recognised globally by boards, auditors, and enterprise procurement teams as the benchmark for security management competence.

I understand how security connects to business risk — not just technical controls. This is the credential that earns board-level credibility.

CRISC

Certified in Risk and Information Systems Control

Awarded to practitioners who can identify, assess, and manage IT risk across the enterprise — connecting technical exposure to commercial consequence.

I can translate technical risk into the commercial terms your board, investors, and insurers will actually understand and act on.

ISO 27001 LA

ISO 27001 Lead Auditor

Qualified to conduct formal ISO 27001 audits — which means understanding exactly how external auditors think, what they look for, and what trips organisations up.

Your program gets built to pass — not just to comply. I know the auditor's checklist because I've used it.

24+ YRS

Large Tech · FinTech · HealthTech · SaaS

Two decades across large enterprises, regulated FinTech and HealthTech environments, and fast-moving SaaS companies — across Australia and internationally.

I've seen what breaks security programs at scale — in your industry, at your stage. That pattern recognition is what you're getting access to.

Let's Talk

Security on the to-do list? Let's change that.

If you're scaling and security keeps landing in the "important, but later" pile — whether that's an audit coming up, a deal blocked by a questionnaire, or a board starting to ask harder questions — I want to have that conversation.

It's not a sales call. No pitch, no deck, no pressure. Thirty minutes, and you'll walk away knowing exactly where you stand, what the fastest path forward looks like, and whether Logic Weave is the right fit.

If we're not the right fit, I'll tell you that too.
