When you think about cybersecurity services and best practices, defence contractors might not be the first organisations that spring to mind. But these companies face some of the most sophisticated cyber security threats on the planet, and they’ve developed approaches that work for businesses across every sector.
Defence organisations are prime targets for cyber attacks ranging from opportunistic hackers to nation-state actors. They hold the kind of data that keeps intelligence agencies awake at night: weapons systems designs, operational plans, critical infrastructure blueprints, and sensitive personnel information. According to The Cove, defence contractors face “persistent cyber threats and attacks” as part of their daily reality.
The implications extend far beyond military applications. Data security failures in defence supply chains can expose network security vulnerabilities across entire industries. When organisations that face the highest threat levels get breached, it’s worth understanding what happened and what the rest of us can learn.
The stakes couldn’t be higher. When Israeli defence contractors were breached in 2024, the ripple effects reached Australia’s Land 400 program and exposed information about our Redback infantry fighting vehicles. Hackers claimed months-long access, leaking tens of thousands of emails and scanned identity documents from Australian suppliers like IKAD Engineering. The breach also touched naval projects including Hunter Class and Collins Class submarine-related data. As the ABC reported, even “non-sensitive” data can help adversaries map systems, personnel and processes.
The question isn’t whether your business faces the same level of threat as a defence contractor. It’s whether the security approaches that work in high-threat environments can help protect your business from the increasingly sophisticated attacks targeting Australian organisations across all sectors.
Treat Cybersecurity as a Licence to Operate
In the defence world, cybersecurity isn’t a nice-to-have – it’s a fundamental requirement for doing business. US defence contractors must comply with the Defense Federal Acquisition Regulation Supplement (DFARS), which mandates implementing NIST SP 800-171 controls and reporting incidents within 72 hours. Fail to meet these standards? You don’t get the contract. It’s that simple.
The Cybersecurity Maturity Model Certification (CMMC) takes this further by requiring contractors to not just implement security practices, but actively demonstrate and document them through third-party assessments. Major primes like Lockheed Martin are now pushing suppliers to reach CMMC Level 2, making cyber readiness a key factor in supplier selection. For contractors handling sensitive information, CMMC Level 2 is increasingly non-negotiable, and lagging suppliers risk losing their place in the supply chain entirely.
Australia is following a similar path. Since September 2024, all Defence Industry Security Program (DISP) members were required to achieve ASD Essential Eight Maturity Level 2 by November 2025 – a deadline that has now passed. The old “Top 4” approach? No longer acceptable. As CyberWyze reported, this represented a significant uplift in baseline security expectations, moving from partial implementation to comprehensive coverage of all eight mitigation strategies.
The lesson for Australian businesses is clear: comprehensive security frameworks are rapidly becoming a competitive differentiator and a barrier to entry. If you’re in critical infrastructure, healthcare, finance or government supply chains, expect similar compliance requirements to flow down to you. What’s mandatory in defence today often becomes standard practice across regulated industries within a few years. Beyond compliance, treating security as fundamental to operations protects your reputation, client relationships and business continuity.
Use Proven Frameworks, Don’t Reinvent the Wheel
Defence contractors don’t make up their own security approaches. They use battle-tested frameworks like NIST SP 800-171 (which defines 110 controls across 14 domains including access control, incident response, and system and communications protection) or Australia’s ASD Essential Eight mitigation strategies. These frameworks provide structure, help prioritise investments, and give auditors clear benchmarks.
The Essential Eight focuses on eight strategies that, when implemented properly, can prevent up to 85% of cyber attacks. We’re talking about fundamentals like application control, patching operating systems and applications, multi-factor authentication, and regular backups. DISP’s shift from requiring four strategies at Maturity Level 1 to requiring all eight at Level 2 sends a clear message: partial adoption doesn’t cut it anymore.
The maturity model approach is particularly valuable because it provides a roadmap. Rather than treating security as binary (secure or not secure), these frameworks define progression through maturity levels. Level 1 might be basic implementation, Level 2 adds regular review and improvement, and Level 3 incorporates continuous monitoring and automated responses. This graduated approach helps organisations prioritise investments and demonstrate measurable security improvement over time.
Australian defence SMEs are now engaging specialists to uplift their Essential Eight maturity. Winbasic, for example, helps organisations move to Essential Eight ML2 with a focus on evidence and governance, not just technical configuration – backed by our team’s ASIO and Australian Defence Force clearances that give us practical experience in high-security environments and the rigorous standards they demand.
For your business, this means choosing a recognised framework – whether it’s Essential Eight, NIST or ISO 27001 – and implementing it to a defined maturity level. Don’t create your own control set from scratch. Stand on the shoulders of giants who’ve already figured out what works across thousands of implementations.
Your Supply Chain is Your Attack Surface
Here’s where defence contractors are miles ahead of most businesses: they treat supplier cyber posture as seriously as their own security. Lockheed Martin explicitly links supplier status to CMMC Level 2 compliance, integrating advanced security measures as part of building a resilient, digitally enabled supply network. Under DFARS requirements, contractors must flow down NIST SP 800-171 requirements to subcontractors and ensure they’re actually implemented – this is a formal responsibility, not just a suggestion.
This supply chain focus reflects a hard-learned lesson: you’re only as secure as your weakest link. In Australia, organisations in regulated industries are discovering that security requirements now extend throughout their entire network of suppliers and subcontractors, creating accountability across the entire ecosystem.
This isn’t theoretical. The Land 400 breach happened because hackers compromised Israeli partners and Australian suppliers, demonstrating how indirect access can expose sensitive project details. Even where only “non-sensitive” information and employee records are compromised, the aggregate intelligence can be devastating. Adversaries use this data to map organisational relationships, understand project timelines, identify key personnel, and plan more targeted attacks.
For Australian businesses across all sectors, this means:
- Including specific security requirements in vendor contracts, not just general liability clauses
- Assessing vendor cyber maturity before engagement, using frameworks like Essential Eight as benchmarks
- Treating third-party access, data sharing and system integrations as first-order risks that require active management
- Asking suppliers about their incident response plans and reporting commitments – and verifying they actually exist
- Conducting periodic reviews of vendor security posture, not just one-off assessments at contract signing
Your security is only as strong as your weakest supplier. Defence contractors learned this the hard way – you don’t have to.
Build Security into Your Culture
Defence organisations understand that cyber resilience isn’t just about technology – it’s fundamentally about people. The Australian Army emphasises that “good cyber hygiene is the responsibility of every soldier and officer,” backed by comprehensive professional development resources. This isn’t about creating paranoia; it’s about building institutional awareness where security becomes second nature.
The Australian Defence Force runs the ADF Cyber Gap Program, a 12-month initiative that runs parallel to tertiary study and covers threat emulation, incident response, vulnerability assessment and more. They’re treating cyber skills as a strategic capability, not just an IT problem. This investment in developing home-grown talent ensures the organisation has people who understand both the technical and operational context of security threats.
Defence industry SMEs working on Essential Eight uplift with providers like Tesserent emphasise governance, evidence and security culture alongside technical configuration. Passing DISP assessments isn’t just about deploying the right software – it requires cultural change where security considerations are embedded in decision-making at every level.
This cultural approach extends to basic cyber hygiene practices. Defence organisations drill their personnel on recognising phishing attempts, handling sensitive information appropriately, reporting suspicious activity promptly, and understanding why security protocols exist rather than seeing them as bureaucratic obstacles.
For your organisation, this means making basic cyber hygiene part of everyone’s job description. Invest in structured training programmes that go beyond annual tick-box compliance. Create clear career paths for security professionals. Make security awareness as routine as occupational health and safety. Most importantly, ensure leadership visibly prioritises security – cultural change starts at the top.
What This Means for Your Business
You don’t need to be a defence contractor to benefit from their hard-won cybersecurity lessons. The same principles that protect sensitive military information can protect your client data, intellectual property, and business operations. Here’s what Australian businesses should take away:
Start with the ASD Essential Eight and aim for Maturity Level 2 as your baseline. These strategies work regardless of your industry – they’re about fundamentals like controlling what software runs on your systems, keeping everything patched, using multi-factor authentication, and maintaining reliable backups. This isn’t about box-ticking – it’s about implementing controls that genuinely reduce your risk. The beauty of these frameworks is they provide a clear roadmap rather than leaving you to figure out security priorities from scratch.
Treat cybersecurity as a business enabler, not just a cost centre. Defence contractors can lose lucrative contracts worth millions for failing compliance audits. While your industry might not have identical requirements yet, treating cyber maturity as a competitive advantage positions you ahead of less prepared competitors. In tender processes across all sectors, demonstrating robust security practices increasingly differentiates winning bids from also-rans. Your clients want to know their data is safe with you.
Secure your supply chain by requiring cyber self-assessments from vendors, setting minimum baseline controls, and verifying rather than trusting. The Land 400 breach demonstrates that third-party compromises can harm you just as much as direct attacks. Consider implementing vendor risk assessments that evaluate security posture before granting access to your systems or data.
Most importantly, invest in your people. Look to the ADF Cyber Gap Program as a model for building internal capability. Make security everyone’s responsibility, backed by training, clear policies and leadership commitment. The most sophisticated technical controls fail when employees don’t understand why they exist or how to use them properly.
Defence contractors operate in one of the most hostile cyber environments imaginable. The practices they’ve developed under fire offer valuable blueprints for any Australian business serious about protecting its data, reputation and competitive position. The frameworks work. The approaches scale. The cultural practices translate across industries.
Understanding what cybersecurity means for your business and how to improve it starts with learning from organisations that have no choice but to get it right. The frameworks, approaches and cultural practices that keep defence contractors secure can be adapted to businesses of any size, in any sector.
