Darwin cyber security
Penetration testing and compliance for Darwin businesses, including Defence and critical infrastructure.
We specialise in cyber security services
What drives security spending in Darwin. Defence and energy. Darwin hosts a significant and growing Australian Defence Force presence alongside rotational United States forces, and the supply chain that supports both. The Port of Darwin and the offshore gas industry add critical infrastructure obligations, and the Northern Territory Government and health services round it out.
What makes the Territory different is the ratio. In most cities the Defence supply chain is a niche. In Darwin it is a large share of local business, which means security obligations arrive at firms that have never had a compliance function.
The frameworks that come up most.
- DISP membership for anyone in the Defence supply chain, covering governance, personnel, physical and ICT security.
- Security of Critical Infrastructure Act for port, energy and gas operators, with obligations tightened by the 2025 amendments.
- ASD Essential Eight as a baseline, and usually the first thing a prime contractor asks you to evidence.
- ISO 27001 where a national or international parent company requires it.
- Cyber Security Act 2024 ransomware payment reporting, in force since 30 May 2025 for businesses over $3 million turnover, with 72 hours to notify the Australian Signals Directorate.
The constraint nobody mentions. Specialist security skills are genuinely scarce in the Territory, and the market is small enough that most organisations end up buying from interstate. The thing to watch is continuity. A tester who flies in once and is never heard from again produces a report, not a relationship, and the retest six months later is where that matters. We work with Territory clients remotely with the same named people each time.
CREST Accredited Penetration Testing in Darwin
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 Darwin that matters most for Defence and energy supply chain work, where accreditation is checked early and where the discipline it covers is checked too.
What we actually do. Penetration testing across networks, web applications, APIs and cloud, Essential Eight maturity assessments, and fixed-price ISO 27001 programmes. We are Brisbane based, half an hour behind you, and we work with Darwin clients remotely with on-site attendance where the environment genuinely requires it.
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 Darwin Businesses.
Territory scopes frequently involve Defence supply chain evidence or port and energy environments. We map findings to the control set you are being assessed against, and where a control system environment is in scope we agree the testing approach before we touch anything.
