Cyber Security for Defence Suppliers: Protect IP, Pass DCPP Audits, and Retain MoD Contracts

Tier 2/3 defence suppliers buy cyber security to pass audits and retain contracts. Every MoD contract is assigned a Cyber Risk Profile under the Defence Cyber Protection Partnership (DCPP), and Def Stan 05-138 dictates the controls required at each level. CE+ is legally required to bid on any contract handling Ministry of Defence Identifiable Information (MODI). A failed DCPP audit or lapsed CE+ locks suppliers out of the MoD supply chain regardless of engineering capability.

  • CREST accredited penetration testing for defence supplier networks, OT, and supplier portal access
  • CE+ and ICA certification body meeting Def Stan 05-138 baseline and DCPP audit requirements
  • Def Stan compliance advisory across Very Low, Low, and Moderate cyber risk profiles

Why Defence Suppliers Need Specialist Cyber Security

  • Def Stan 05-138 assigns every MoD contract a cyber risk profile requiring specific controls. Suppliers bidding on Moderate profiles must demonstrate substantially more than CE+ baseline
  • Tier 1 primes (BAE, Babcock, Thales) increasingly mandate independent penetration testing before connecting tier 2/3 suppliers to their portals
  • Threat actors hack tier 3 suppliers not to steal from them but to use their VPN credentials as trusted backdoors into tier 1 prime networks
  • Precision engineering firms hold OFFICIAL-SENSITIVE CAD/CAM files on factory networks running legacy OT with unpatched operating systems
  • Nation-state actors target advanced materials R&D, dual-use technology blueprints, and defence electronics IP to bypass years of development investment
  • Ransomware locking a component manufacturer halts the prime’s multi-billion-pound assembly line under JIT delivery models

Frequently Asked Questions

Why are tier 2/3 defence suppliers targeted by threat actors?
Attackers compromise smaller suppliers to steal VPN and portal credentials providing trusted backdoor access into tier 1 prime networks. Tier 2/3 suppliers hold valuable but less protected OFFICIAL-SENSITIVE design data and manufacturing IP.
What does Def Stan 05-138 require from defence suppliers?
Every MoD contract is assigned a DCPP Cyber Risk Profile. Def Stan 05-138 dictates the security controls required at each level from Very Low through Moderate. We help suppliers meet the specific controls their contract risk profile demands.
How does CE+ relate to MoD contract eligibility?
CE+ is legally required to bid on any MoD contract handling Ministry of Defence Identifiable Information. A lapsed certificate locks suppliers out of bidding regardless of engineering capability or existing relationships.
How do you secure defence manufacturing OT and CNC machines?
We assess factory floor OT including CNC machines and MES running legacy operating systems. Testing covers IT/OT segmentation, production system access controls, and Bill of Materials integrity.
How do you protect OFFICIAL-SENSITIVE design data and blueprints?
We assess CAD/CAM and PLM platform security, file transfer controls, and access management for design data. Testing identifies where OFFICIAL-SENSITIVE blueprints could be exfiltrated through compromised networks or insider access.
What training addresses fake RFP phishing targeting defence procurement?
Targeted phishing simulations using spoofed MoD and prime contractor domains with fake RFPs and malicious CAD attachments. Training designed for procurement, engineering, and finance teams handling defence contracts.
How do you help with prime contractor security audits?
We deliver CREST accredited penetration testing and Def Stan gap analysis producing the evidence tier 1 primes require. Our reports directly support the independent testing mandated before supplier portal connection.
What is IASME Cyber Assurance and how does it help defence suppliers?
ICA builds on CE+ controls to cover security, recovery, and continuity. As an authorised body, we help defence suppliers demonstrate broader resilience beyond CE+ baseline to primes and MoD auditors.
How often should defence suppliers conduct penetration testing?
Annual CREST accredited testing for Def Stan and CE+ maintenance. Contract renewals, new prime portal connections, or manufacturing system changes should trigger immediate assessment.
What makes Cyphere's approach unique for defence suppliers?
We understand that defence suppliers buy cyber security to pass audits and retain contracts. Our assessments are aligned to Def Stan 05-138 risk profiles and DCPP requirements, delivering evidence that satisfies MoD and prime contractor obligations.
