How Much Does DISP Certification Cost for Businesses in Australia?
If you’re trying to work out the DISP certification cost in Australia, the honest answer is: it depends. There is no single fee you pay and walk away with a certificate. DISP membership works differently to other compliance frameworks, and understanding where the costs actually come from will help you plan your budget and avoid surprises down the track.
What Is DISP Certification?
DISP stands for the Defence Industry Security Programme. It is administered by the Defence Security Authority (DSA) and is designed to ensure Australian businesses working with the Department of Defence have the right security controls in place.
DISP membership is structured across four security domains: Security Governance, Personnel Security, Physical Security, and ICT/Cyber Security. Each domain has specific requirements that must be met before your application can be approved. Membership is mandatory for many defence contracts and strongly recommended for any business looking to participate in the Australian defence supply chain.
Does DISP Have a Direct Membership Fee?
No. The Australian Government does not charge a fee to apply for or hold DISP membership. The application itself is free.
But that is where the “free” part ends. The costs come from implementing and maintaining the security measures required to achieve and keep your DISP membership. Depending on where your business is starting from, those implementation costs can be significant.
Breaking Down the Real DISP Certification Costs
Here is where most businesses actually spend money:
Essential Eight Maturity Level 2 implementation
Since 2025, DISP requires all eight ASD Essential Eight mitigation strategies implemented at Maturity Level 2 across your entire corporate IT environment. Previously, only the “Top 4” strategies at Maturity Level 1 were required. This is the single biggest cost driver for most businesses. The cost of Essential Eight ML2 uplift varies considerably. The size of your environment and the maturity of your existing controls are the two biggest factors that will determine your investment.
Security governance documentation
DISP requires a genuine security governance framework, not a set of policies downloaded from the internet. You need board-level oversight, documented risk management processes, incident response procedures, and third-party security requirements. If you do not have these in place, building them from scratch takes time and expertise.
Personnel security
Depending on your DISP membership level, key staff may require Australian Government security clearances. Clearances are funded separately and can take several months to process. You will also need documented vetting and ongoing suitability monitoring procedures.
Physical security
Secure area access control, visitor management, and classified information storage are all assessed by the DSA. Businesses that operate from shared office spaces or do not currently have dedicated secure areas may face physical infrastructure costs to meet these requirements.
Consulting support
Most businesses working through DISP for the first time engage a consultant. Given the complexity of all four domains, the change to Essential Eight ML2, and the 90-day DSA processing timeline (which only starts once your application is complete), having experienced guidance usually reduces the overall cost by avoiding delays and rework.
If you are not sure where your business currently stands against DISP requirements, a gap analysis is the right first step. Siege Cyber conducts DISP readiness assessments across all four security domains, giving you a clear picture of what needs to be done before you submit your application.
what is the cost of DISP Certification?
The cost of getting DISP-ready depends entirely on where your business is starting from. A business with mature security controls already in place will have a much shorter path than one building its governance and cyber security posture from scratch.
The most reliable way to understand your investment is through a structured gap analysis across all four DISP domains. This gives you a clear picture of what needs to be done and how long it will take.
Siege Cyber’s DISP Certify package is structured at $4,950 per month on a 12-month subscription — a fixed, predictable cost for organisations with up to 50 employees. This covers the full journey from gap analysis through to application-ready compliance, including CSO advisory, all policy and procedure documentation, and Annual Security Report preparation.
What Does a DISP Consultant Cost?
Engaging a consultant to guide you through the process is not an optional extra for most businesses. Meeting all four DISP domains simultaneously — governance, personnel, physical, and ICT/cyber security — while managing day-to-day operations is a genuine challenge, and gaps in your application will extend your timeline considerably.
Consultant fees in Australia are typically structured as either a fixed-price engagement or a monthly subscription over 12 months. A subscription model tends to work better for DISP because the process is not linear. You will likely need ongoing advisory support as the DSA reviews your application and requests evidence or clarifications. Siege Cyber’s DISP Certify package is built around this model, offering a fixed monthly rate across a 12-month engagement so you have consistent support without unexpected costs along the way.
When comparing consultants, look beyond the headline price. Consider what is included. Explore whether the engagement covers policy and procedure development, CSO advisory, incident response planning and Annual Security Report preparation, or whether they’re charged separately? Understanding exactly what is in scope before you sign will save you from cost blowouts mid-engagement.

How Long Does It Take and How Does That Affect Cost?
Most businesses complete their DISP preparation and submit their application within a 12-month engagement. Once submitted and assigned to a processing officer, the DSA takes approximately 90 days to assess your application, so factoring that into your overall timeline from the start is important.
The 12-month timeframe is not arbitrary. DISP requires demonstrated, sustained security governance across all four domains. The DSA wants evidence that your controls are embedded in how your business actually, which takes time to establish properly.
Businesses that attempt to shortcut the process, particularly around Essential Eight ML2 implementation, often have deficiencies flagged by the DSA. This extends the timeline beyond 12 months and adds remediation costs on top of what was already spent. Structuring your engagement correctly from day one is significantly more cost-effective than rushing and reworking later.
Is DIY DISP Preparation Worth It?
Some businesses do attempt to manage DISP preparation internally. It is possible, particularly for larger organisations with dedicated security or IT teams. However, the 2026 Essential Eight ML2 requirement has raised the technical bar considerably, and the governance and documentation requirements demand experience with Australian Government frameworks like the Protective Security Policy Framework (PSPF) and Defence Security Principles Framework (DSPF).
The businesses that struggle most with DIY DISP preparation are those that underestimate the documentation and evidence requirements. The DSA wants to see genuine, sustained governance, not a folder of policies created the week before submission.
