Melbourne cyber security
Penetration testing and compliance for Melbourne businesses, from an Australian team.
We specialise in cyber security services
What drives security spending in Melbourne. Melbourne has the broadest industrial mix of any Australian capital, and that is the single most useful thing to know about security here. Financial services and superannuation sit alongside the country's largest health and medical research cluster, its biggest university concentration, advanced manufacturing, and a deep logistics industry built around the Port of Melbourne.
The practical consequence is that the compliance driver is rarely the same twice. A medical research institute is worried about health data and ethics approvals. A freight operator is worried about operational technology and critical infrastructure obligations. A superannuation administrator is worried about APRA. A university spinout is worried about the enterprise customer asking for SOC 2. These are not the same engagement, and a provider who treats them as one will scope your test badly.
The frameworks that come up most.
- ISO 27001 as the general-purpose answer for enterprise and government supply chains.
- SOC 2 for the technology sector, particularly anyone selling into the United States.
- APRA CPS 234 for financial services and the third parties they depend on.
- Victorian Protective Data Security Standards for Victorian Government suppliers, which catches more organisations than expected.
- Security of Critical Infrastructure Act for port, energy and data storage operators, with obligations tightened by the 2025 amendments.
- Privacy Act obligations across health, education and research, where the data is sensitive and the reputational cost of a breach is high.
The pattern we see in Melbourne. Clients here frequently arrive with an incomplete internal attempt already underway, usually a policy set built from a downloaded template that no auditor will accept, and a genuine belief that they are most of the way there. We are comfortable picking that up rather than starting again, and we will tell you honestly which parts are salvageable and which need to be rewritten. That conversation is cheaper before an audit than during one.
CREST Accredited Penetration Testing in Melbourne
Siege Cyber is a CREST-accredited company for penetration testing. The accreditation is assessed and held at company level and is verifiable on the CREST member register. In Melbourne that matters across an unusually broad industrial mix, because whether the buyer is a health service, a manufacturer or a bank, the first question in a vendor review is who did the testing and what they are accredited to do.
If you are collecting penetration testing quotes specifically, we have written a fuller guide to penetration testing costs in Melbourne covering what moves a quote and how to compare two of them properly.
What we actually do. Web application, API, internal and external network and cloud penetration testing, and fixed-price compliance programmes reaching ISO 27001 certification at month five or SOC 2 Type 1 at month four. We are Brisbane based and work with Melbourne clients remotely, attending on site where it genuinely helps rather than as a billable default.
Partnering with Managed Service Providers (MSP)
We partner with other cyber security organisations, such as MSPs, Resellers, Cyber Insurance providers, Consultants and Compliance professionals to maximise their cyber security capabilities and protect their clients.
By building relationships with our partners, we are able to better understand and service their clients' need. Our partners can trust that their clients receive the industry-best cyber security services from Australia's leading cyber security experts.

testing methodologies
Cyber Security Testing Methods to Suit Melbourne Businesses.
Melbourne scopes vary more than anywhere else we work, so we scope deliberately rather than from a template. A health research environment, a logistics operator running control systems and a fintech API need three different tests. We will tell you at the scoping call which one you actually need, including when that is a smaller engagement than you were expecting.
