Brutally honest
cyber security —
because your risk
decisions need to
stand up to scrutiny
Cliffside is where risk meets clarity. We start with assessment, then tell you what you actually need — even when it's not what we sell. Defensible, audit-ready security for Australian organisations.

Enterprise security.
Without the enterprise headcount.
DeltaPAE — a coal mine and power station on the NSW Central Coast — faced aggressive technology transformation with a two-person security team. Cliffside became their embedded security office, delivering cloud migration security, ISO 27001/2-aligned governance, and 24×7 SOC services. Zero additional permanent headcount required.
I feel like I've got a great cybersecurity team when I've got Cliffside. They leave no stone unturned.
Leah Christiansen — Security Manager, DeltaPAEThe security vs. reality conflict.
Most cybersecurity programmes in Australia are built around what vendors sell, not what organisations actually need. The result is a growing gap between reported compliance and actual resilience — and boards that can't tell the difference until it's too late.
Cliffside was built to close that gap. We're ISO/IEC 27001 certified ourselves — our consultants have held Lead Auditor credentials since 2008. We know the difference between passing an audit and genuinely managing information security risk. Our advice starts with an honest assessment, and it doesn't change based on what products we have to sell.
The average Australian data breach now costs $4.26 million. ASD recorded a cybercrime report every six minutes in 2023–24. The organisations that survive aren't the ones with the longest vendor list — they're the ones with clear, evidence-led security programmes that can be defended when the pressure comes.
How we work →SIX PILLARS. ONE HONEST STANDARD.
Six practice areas — each aligned to how Australian organisations actually make security decisions. Security without theatre, automation without naivety.
Strategy &
Architecture
Security designed for your environment — not a templated framework bolted on. We align security investment to actual business risk, build evidence trails boards can defend, and give you a roadmap that doesn't restart every year.
Compliance
& Audits
ISO 27001, APRA CPS 234, Essential Eight — navigated efficiently, without the compliance theatre. We're certified ourselves. We know the difference between passing an audit and being genuinely secure.
Cloud
Security
AWS and Azure specialists. Microsoft partner for M365 security — Defender, Intune, Entra ID and the full security stack. Cloud security designed in from day one, not bolted on after migration.
Managed
Services
Continuous security without the continuous overhead. Managed SOC, ongoing security awareness, and third-party risk management — the capabilities that keep working between assessments.
Security Testing
& Assurance
Find real weaknesses before attackers do. Our OSCP, OSWE, OSCE and CREST-certified testers deliver penetration testing calibrated to your actual risk, not a generic fixed-price scope.
Process
Automation
Automate business processes that handle sensitive data — with security baked in, human approval gates, and an AI-first approach. If you don't, your competitors will.
ISO 27001 is our primary market entry point.
We're ISO/IEC 27001:2022 certified ourselves — our Lead Auditor credentials go back to 2008. We offer two proven pathways to certification: a Cybereen-led engagement that cuts assessment time significantly for organisations moving away from spreadsheet-based approaches, and a Vanta-accelerated pathway for continuous compliance monitoring that reduces audit preparation time by up to 85%. Our Lighthouse Assessment gives you a transferable, honest picture of your readiness — no lock-in, just clarity.
The Cliffside Lighthouse Assessment.
Most security assessments tell you what you want to hear. The Lighthouse Assessment tells you what you need to know. It's an independent, transferable evaluation of your current security posture — with a prioritised gap analysis you can take to any provider, any auditor, any board.
The Lighthouse Assessment is vendor-neutral by design. You own the output. Use it with Cliffside, take it to another provider, or use it to guide internal remediation. No lock-in. Just clarity.

ISO 27001 Pre-Certification Guide: The Honest Preparation Roadmap.
Most organisations start their ISO 27001 journey with the wrong question. It's not "how do we pass the audit" — it's "how do we build an ISMS that actually manages information security risk."

Most Australian organisations targeting the Essential Eight stop at Maturity Level 2. Here is what genuinely achieving ML3 requires — and why it is harder than most assessors admit.
