Architecture Review and design
A Cube Cyber architecture review assesses how your environment is actually built, network, cloud, identity and controls, against the threats that matter to your sector, and delivers a prioritised roadmap and target-state design your team can implement. It suits organisations that have grown, migrated or merged faster than their security design, and need to know where the structural weaknesses are before an attacker or an auditor finds them.
Book An Architecture Review
Reviews usually start when one of these becomes hard to ignore
The most common triggers are a change of security leadership wanting an independent baseline, a board or regulator asking for evidence of security posture, an upcoming certification or uplift program that needs a starting point, and the aftermath of a merger, migration or incident that made the gap between the documented and actual environment impossible to ignore. A review also pays for itself before major investment decisions, it is considerably cheaper to assess the architecture than to buy the wrong program.
Core capabilities & deliverables
Current-state assessment
A practitioner-led review of network architecture, cloud platforms, identity, data flows and control placement as they actually operate, built from configuration, traffic and interviews rather than the diagram on the wiki. The undocumented parts usually matter most, and we go looking for them.
Attack-path analysis
We assess the environment the way an attacker would traverse it, initial access, lateral movement, privilege escalation and impact, so findings are expressed as real paths to real assets rather than isolated control gaps. This is what makes the roadmap defensible in front of a board.
Threat and risk alignment
Findings are weighted against the threats relevant to your sector and obligations, ransomware and extortion, supply chain compromise, insider misuse, and the regulatory
Target-state architecture design
A pragmatic design for where the environment should be, segmentation model, identity architecture, cloud security baseline and control placement, shaped by your operational constraints, budget realities and the systems that cannot change.
Prioritised roadmap
A staged transition plan sequenced by risk reduction per unit of effort, quick wins separated from structural work, each stage scoped clearly enough to become a project. The roadmap is written to survive contact with procurement, budgeting and change management.
Executive and board reporting
A clear narrative of current risk, target state and the investment case, in language a board can act on, because architecture programs succeed or fail on executive sponsorship.
Reviews follow a four-stage path, typically over a few weeks depending on environment size
Scope and Discover
Scope and discover Agree the boundaries, systems, sites, cloud platforms, and gather the real picture through configuration review, network data and structured interviews with the people who run the environment.
Assess
Analyse architecture against attack paths, sector threats and the frameworks your obligations reference, testing assumptions rather than accepting them.
Build
Develop the target-state architecture and validate it with your technical teams, a design nobody can operate is a document, not an architecture.
Roadmap and debrief
Deliver the prioritised roadmap, walk through findings with technical teams and executives separately, each audience needs a different conversation, and agree next steps.
Assessments and designs align to the frameworks that matter in Australia: the ASD Essential Eight and ISM, NIST Cybersecurity Framework, ISO 27001 control objectives, and IEC 62443 where operational technology is in scope. Where the review feeds a certification or regulatory program, evidence is structured so our GRC practice, or yours, can use it directly.
NISTISO 27001IEC 62443Frequently asked questions
A focused review of a mid-sized environment typically runs a few weeks from kick-off to debrief, larger or multi-site environments run longer, and we agree the timeline at scoping. The constraint is usually access to the right people, an hour with the engineer who runs the firewalls is worth a week of document review.
A current-state assessment with attack-path led findings, a target-state architecture design, a prioritised and staged roadmap, and separate technical and executive debriefs. Everything is written to be acted on, findings tie to specific changes, and roadmap stages are scoped so they can move straight into planning.
No, and they answer different questions. A review examines how the environment is designed and finds structural weaknesses; a penetration test exploits the environment as built and proves what is possible today. They complement each other, and review findings often shape the most valuable test scope. We deliver both.
No. Reviews consistently find that organisations own more capability than they operate, segmentation features unused, identity controls unconfigured, logging switched off. The roadmap starts with extracting value from what you have; new investment is recommended only where a genuine capability gap remains, and the design stays vendor-agnostic.
Yes. OT and converged IT/OT environments are a Cube Cyber specialisation, with more than 10 years' experience across industrial, clinical and building systems. OT discovery uses passive, non-disruptive methods, and designs align to IEC 62443 zones and conduits alongside the corporate frameworks.
Less than you might fear, but the right people matter: the engineers who run the network, identity and cloud platforms, an application owner or two for the systems that matter most, and an executive sponsor for the debrief. We work around operational calendars, and most participants contribute a few hours across the engagement rather than days.
