Airlock Digital vs Cynch Security (2026): Which Australian Cyber Tool Do You Actually Need?

Editorial guidance, not security advice. This comparison is independent editorial opinion to help you shortlist tools. It is not cyber security, legal or compliance advice. No single product makes you "Essential Eight compliant" on its own. For anything material — an incident, an insurance condition, a compliance obligation — engage a qualified IT provider, MSP or security consultant.

Two Australian-built cyber security tools, both shaped around the Australian Cyber Security Centre's Essential Eight, both names we rate. And yet putting them head-to-head is almost unfair, because they do opposite jobs. Airlock Digital enforces. Cynch Security guides. One physically stops unapproved software from running on your machines. The other tells a non-technical owner what to fix, in plain English, and hands them a report to wave at an insurer.

So this isn't really "which is better" — it's "which job do you need done first." This piece sorts that out: AUD pricing, what each actually delivers, where each fits the Australian small business, and a clear recommendation by situation. Both earned strong scores in our full reviews; we cite those here rather than re-scoring.

Quick look

Note both tools score 5/5 on Australian Fit, so the Australian Fit gate is cleared by both and is not the deciding factor between them. The gap in total score (22 vs 18) reflects depth and value within their own categories, not a difference in how well they serve Australians.

What it costs in Australia

Pricing is where these two diverge hardest — one is a published number, the other a sales conversation.

Cynch publishes one tier, one number: A$149/month per business, roughly A$1,800 a year before any discount. As an AUD-billing Australian vendor, GST applies the standard way — the pricing page doesn't state whether the A$149 is inclusive or exclusive, so check your tax invoice. On the house GST basis that's about A$163.90 a month including GST if the published figure is GST-exclusive (A$149 × 1.10). A GST-registered business can generally claim the credit; confirm with your accountant.

Airlock won't give you a sticker price at all. It's sold per endpoint, usually through partners and MSPs, and scaled to your fleet — so you can't comparison-shop it from a pricing page. The only public sizing reference is a commissioned Forrester study modelling a 20,000-endpoint enterprise (US$1.7m cost, 224% three-year ROI), which is a large-enterprise signal, not a small-business per-seat figure. Practically: budget for a sales conversation, and get the number in writing.

The honest read: Cynch is the easy one to budget for and try; Airlock is opaque but buys you a control insurers and auditors actively reward.

The core difference: enforce vs guide

If you take one thing from this comparison, take this.

Airlock does the protecting. It implements application control — the ACSC rates this among the most effective of the Essential Eight — to Maturity Level 3, the top tier. Its model is deny-by-default: nothing runs on a protected machine unless it's been explicitly approved, by cryptographic hash, publisher signature, file path or parent process. That stops ransomware and unknown malware by design, not by guessing. It's deterministic, cross-platform (Windows, macOS, Linux), and runs on-prem, in the cloud, or fully air-gapped.

Cynch does the directing. It assesses your posture, scans your Microsoft 365 or Google Workspace configuration, scores your "cyber fitness," and hands back a short, prioritised, plain-English to-do list — turn on MFA, fix this sharing setting — with human coaches on demand to translate the jargon. It produces a validated report you can give an insurer or a tender. But it implements nothing. When Cynch says "turn on MFA," you (or your IT support) still do it.

Put plainly: Cynch tells you that you should have application control. Airlock is the application control. They sit at different points on the same journey — Cynch is the map, Airlock is one of the harder roads on it.

Feature and use-case diff

Neither is an AI product, and we say so plainly in both full reviews — they're in our Cybersecurity & Data Protection category on Australian fit and audience fit, not AI credentials. Airlock's only "intelligence" is the VirusTotal and ReversingLabs reputation data that helps a human build the allowlist faster. Cynch's is a curated recommendation library plus real coaches.

Who should pick which

This is a use-case split, not a winner-takes-all. Match the tool to where you actually are.

Pick Cynch Security if you're a non-technical sole trader or small operator who knows you "should do something about cyber" and has no idea where to start. You have no IT person, no MSP, and an insurer or tender keeps asking questions you can't answer. Cynch's plain-English task list, human coaching and validated report are built for exactly you — and at A$149/month with a no-card trial, you can start this afternoon. It's the better starting point.

Pick Airlock Digital if you have at least modest IT support — an internal admin or an MSP — and you're under real pressure to harden endpoints: a government tender, a cyber-insurance condition, or a supply-chain contract demanding Essential Eight maturity. Airlock delivers the single most effective anti-ransomware control properly, to Maturity Level 3. It's the better outcome for the hardest control — and it holds our category Top Pick for application control.

The honest answer for many businesses is "Cynch first, then Airlock" — or both at once. Cynch tells you application control is a gap; Airlock fills it. They're complementary, not competing. The only people who should choose neither are those who already pay an MSP to assess and enforce — in which case you may be buying Cynch's job twice.

If forced to name a single overall winner, it's Airlock Digital (22/25 vs 18/25) — but only because it delivers a protective control rather than advice, and that's worth more when the stakes are real. That's not a knock on Cynch, which wins outright for the audience it's built for: the owner who needs a guided first step, not enforcement software they can't run.

Honest limitations. Airlock's pricing is quote-only and its rollout takes weeks of real administration — a solo operator will struggle without an MSP. Cynch guides but doesn't protect, and its data-residency position isn't published, which is worth pressing before you connect a live M365 or Google tenant. Neither tool, on its own, makes you Essential Eight compliant.

Frequently asked questions

Are Airlock Digital and Cynch Security available in Australia?

Yes. Both are Australian-built — Airlock Digital was founded in Adelaide in 2013, and Cynch Security in Melbourne in 2017. Both are shaped around the Australian Cyber Security Centre's Essential Eight.

How much do they cost in AUD?

Cynch publishes one tier at A$149/month per business (roughly A$1,800/year before discounts), with annual, micro-business, new-business and NFP discounts. Airlock is quote-based per endpoint, sold through partners and MSPs, with no published price — budget for a sales conversation.

Is there a free trial?

Cynch offers a 14-day trial with no credit card required. Airlock has no public free option.

Which Australian cyber tool do I actually need?

It depends on your job. Pick Cynch if you're a non-technical sole trader who needs a plain-English to-do list and a validated report for an insurer. Pick Airlock if you have IT or MSP support and face real Essential Eight pressure — it enforces application control to Maturity Level 3.

Does either tool make me Essential Eight compliant on its own?

No. Neither tool, by itself, makes you Essential Eight compliant. Cynch guides and reports but implements nothing; Airlock delivers one control (application control) properly. For anything material, engage a qualified IT provider, MSP or security consultant.
