If you’re a defence supplier, meeting cybersecurity requirements is a critical part of staying eligible for contracts. With the growing danger of cyber threats and a focus on supply chain security, the Ministry of Defence (MOD) has put rigid expectations in place. From the Cyber Security Model (CSM) to Cyber Essentials for defence contractors, there are clear steps suppliers must follow to stay compliant. Here we’ll break down what MOD cyber security requirements really mean, how to meet them, and what defence supplier cyber compliance looks like in practice, just what you need to know.
Why Does Cyber Security Play An Essential Role In The Defence Supply Chain?
Cybersecurity is no longer optional when it comes to defence procurement, it’s essential. Why? Because the threats are getting smarter and more aggressive. Even one weak link in the supply chain can put the entire operation at risk.
The Ministry of Defence (MOD) knows this, which is why cyber risk mitigation is now a part of their procurement process. If you want to win a MOD contract, showing up with proper cyber protection is a must.
Schemes like the Cyber Essentials Certificate and frameworks such as the Defence Cyber Protection Partnership help ensure that every supplier in the chain meets a minimum level of cybersecurity.
Getting certified through the Cyber Essentials Scheme shows that your business takes cyber defence protection seriously and is ready to work within the MOD’s trusted network.
However, the UK Cyber Security Breaches Survey 2025 reports that 74% of large businesses experienced cyber breaches or attacks in the past year, highlighting the continued threats.
Cyber Security Standards Required By MOD & Government Buyers
When it comes to securing a MOD contract, you need to follow specific government-mandated standards. These help protect MOD Identifiable Information, build cyber resilience across the supply chain, and ensure only trusted suppliers get through the door. Here’s what you need to know:
Cyber Essentials & Cyber Essential Plus
The Cyber Essentials certification is often a minimum requirement to work with the MOD. It shows you’ve put basic security controls in place like firewalls, user access, and software updates. Cyber Essentials Plus goes a step further by including an independent assessment. To achieve Cyber Essentials certification, your systems must pass key security checks that reduce the risk of common attacks.
DEFCON 658 and DEFSTAN 05-138
These are the official defence contract clauses. DEFCON 658 outlines what’s expected from suppliers in terms of cyber risk management, while DEFSTAN 05-138 helps you figure out what level of security is needed based on your risk assessment. Together, they guide defence suppliers in applying the right controls to protect sensitive data.
NCSC Guidelines And Secure By Design
The National Cyber Security Centre (NCSC) gives practical advice to help suppliers follow a ‘Secure by Design’ approach baking security into systems from day one instead of adding it as an afterthought. Following NCSC guidance ensures your tech, services, and workflows align with UK government cyber security standards, improving your overall cyber resilience.
Steps To Prepare Your Organisation For Cyber Defence Compliance
Getting your organisation ready for MOD cyber defence compliance isn’t as complex as it sounds. It just takes a clear plan and some focused steps. Here’s how you can do it, even if you’re starting from scratch
Audit Your Current Sceurity Conditions
Start by understanding where you stand. Look at how your data moves, who has access to what, and how your systems are protected. Use the MOD’s Supplier Cyber Risk Profile tool to see what your risk level is. This helps you know what improvements are needed and what level of cyber protection the MOD expects from you.
Obtain The Right Certifications
You’ll likely need Cyber Essentials or Cyber Essentials Plus. These certifications show the MOD that you’ve taken real steps to secure your systems. The process includes a simple checklist, a self-assessment (or external audit for Plus), and then certification. Costs vary, but most small businesses can get started without breaking the bank. Just remember to renew it every year.
Train Staff On Secure Practices
Cybersecurity isn’t just an IT job. Everyone in your team plays a role. That’s why regular training and clear policies matter. Teach your staff how to spot phishing emails, use strong passwords, and report anything suspicious. A slight mistake can lead to a big problem, training helps avoid that.
Monitor & Respond To Emerging Threats
Once your systems are in place, you can’t just set and forget. Use basic threat detection tools to spot anything unusual. Keep your software updated and review access controls often. If you work with other suppliers, make sure their security is strong too, supply chain risk is a big concern for MOD contracts. Staying alert is key to staying compliant.
