Security that works for your business, not against it

For when you need experienced security people, not sales decks. Practical advice, and people who stay to deliver it.

What We Solve

Security doesn't happen in a vacuum. What problem are you trying to solve? A new regulation, an AI rollout, increased visibility, or a team stretched too thin?

Adopt AI without opening new holes

Staff and contractors are using AI and nobody can tell you how much or if your data remains secure. We identify the risks and help you put controls in before somebody does something that can't be taken back.

Keep up with the rules that changed

SOCI, CPS 230, the Privacy Act, Essential Eight's replacement. New obligations landed in 2026, and the only constant is change. We work out what applies to you and close the gaps.

Get projects through security faster

Security review is the slowest step in most delivery pipelines, and the reviewers are rarely the reason. We build the paved road, turn policy into code and put AI on the mechanical parts of assessment, so the secure path is also the fast one.

See where you're exposed

Cloud accounts, identities, code, old cryptography. We give you a live view of where you're exposed and help you fix what matters first.

Be ready before something goes wrong

If the first read of your response plan happens during the incident, it will not go well. We write plans your team can run, then rehearse them until they work.

Work with government

ISM, PSPF, IRAP preparation, DISP and Essential Eight ML2. We've worked through the same requirements ourselves, and we can help you as well.

Add senior depth, fast

Vetted practitioners in your team within days, or a full security function for organisations that don't have one of their own.

What Makes Us Different

We built the firm around what clients kept telling us they couldn't find: honest advice, and people who deliver on it.

Senior People Only

Every consultant is senior, with decades of hands-on work behind them. We have seen what works and what does not.

People First

We care about the people we work with, on both sides of the engagement. Our team enjoys the work, and that shows in what we deliver.

We Finish More Projects than We Start

We take on the hard problems, including the ones other firms have walked away from. Projects get completed, not parked.

Practical and Affordable

We take a risk-based approach. Security does not need to be expensive to be effective, and we will never recommend more than you need.

Small Enough to Care, Connected Enough to Deliver

Global Sentynel is an Australian cybersecurity consultancy built around one idea: clients deserve honest advice from people who know what they are doing. It should be what every consulting firm does, but we have seen too many slick pitch decks that promise the world and can't deliver it.

We are a small, tight-knit team with deep roots in the security industry and a wide network of trusted practitioners across Australia and overseas. That network is what lets us say "global" with confidence. We do not have offices everywhere. We know the right people in the right places, and we call on them when clients need it.

Whether you are a mid-sized business after ongoing support or a large organisation tackling a specific problem, you will always deal with experienced people who give you straight answers.
