Securing UK Manufacturing in 2025 – A Deep Dive into Cybersecurity Risks and Resilience for leaders of UK manufacturers.
Manufacturing small and medium-sized enterprises (SMEs) form the backbone of UK industry, fuelling innovation, export success, and employment. Yet, as they adopt IoT, automation, and digital supply chains, cyber threats have multiplied.
Without robust security, even a single cyber incident can halt production, damage reputations, and disrupt supply chains for weeks or months.
The good news?
Cybersecurity doesn’t have to be prohibitively expensive or complex. With smart self-help approaches and the right MSSP partner, manufacturing SMEs can build resilient, compliant, and future-ready defences.
This guide explores the specific challenges facing UK manufacturing SMEs, with practical steps they can take, and how we as a strategic UK MSSP can turbo‑charge those efforts.
1. Budget Constraints & ROI Justification
The Challenge
One key challenge when it comes to securing UK Manufacturing in 2025 is that many UK manufacturers operate on razor-thin margins. Budget decisions are often binary: invest in tooling and capacity or invest in security. Given the obvious perception of tooling and capacity being a production enabler and cyber being a cost centre, it’s easy to see why cyber is frequently deprioritised until disaster strikes.
Self-Help Actions
- Adopt Cyber Essentials for baseline cyber hygiene.
- Use in-built Windows Defender ATP, automatic updates, and firewall rules on your traditional IT and maintenance terminals to close the basics.
- Map out your IT, OT and IoT environment on a single page, segment everything into logical groupings and implementing that zoning technically to prevent issues in one zone easily impacting another.
- Prioritise patches for internet-facing systems and automation tools but don’t forget to scan update media via standalone sheep dip systems before introduction into the manufacturing environment.
How We Help
- Provide fixed-cost managed service bundles that fit production-led budgets, patch management, detection, support and compliance.
- Help support business investment cases with clear risk assessments and management plans.
- Help change the business perception of InfoSec being a cost centre, to InfoSec being a business enabler. Generating strategic alignment strategies that map out how your security investments enable business goals and provide expected cyber ROI calculations. Build a clear cost-benefit analysis for board-level decisions, quantifying downtime avoidance and reputational gain.
2. Talent Shortage & IT-Security Skills Deficit
The Challenge
SME manufacturers often rely on generalist IT staff juggling ERP systems, shop-floor networks, and safety controls, without dedicated cyber expertise.
Self-Help Actions
- Upskill current staff via apprenticeships, bootcamps or NCSC good practice guidance.
- Equip your staff with early warning by signin up to the UK CiSP.
- Attend (and encourage others to attend) community groups, both online and in-person. Like minded professionals sharing problems and approaches to tackling them.
How We Help
- Offer a fractional CISO services, strategic guidance, policy, vendor governance, without hiring full-time.
- Provide attack surface mapping and configuration reviews.
- Implement threat intelligence
- Develop bespoke career development plans that balance staff interests and business objectives.
3. Ransomware & Phishing Risk to Production
The Challenge
An infected CNC machine or compromised PLC can shut lines, destroy IP, or delay deliveries. Phishing remains a top delivery mechanism for attacker and malware footholds, enabling lateral movement into OT systems.
Self-Help Actions
- Enable MFA across remote access, ERP, and office applications.
- Create air-gapped backups of OT configuration and code repositories.
- Teach staff to spot phishing via regular simulations and briefings.
How We Help
- Assess in-house capability and produce gap analysis against business goals or industry good practice frameworks.
- Create and conduct phishing simulations that reflect real world industry specific attacks to measure staff readiness and implement countermeasures.
- Support in creating unique ransomware recovery playbooks for rapid restoration.
4. Regulation & Contract Eligibility Risk
The Challenge
Manufacturers bidding for Ministry of Defence (MoD), Ministry of Justice (MoJ), NHS, or large private sector contracts must satisfy Cyber Essentials Plus or 27001-level security. A single audit failure can cost £100k+ in lost opportunity.
Self-Help Actions
- Leverage Cyber Essentials Plus to qualify for tenders.
- Document data flows, processing impact (DPIAs), record-of-processing (ROPA), and backup schedules.
- Review the CAF good practice outcomes and compare to current security control outcomes.
How We Help
- Perform contract-readiness audits and CAF, NIST, ISO 27001, IEC 62443 or Cyber Essentials Plus preparation with gap analysis.
- Create secure technical policies and audit packs, neatly formatted for prequalification questionnaires (PQQs) and due diligence.
- Provide ongoing compliance monitoring, including patch baselines and security policy enforcement.
5. OT/IoT Risks & Disruption to Production
The Challenge
Industrial IoT and automation increase productivity, but also expand the attack surface. Many devices lack built-in security, and network visibility is often weak.
Self-Help Actions
- Physically segment OT from corporate networks.
- Regularly update firmware and disable unused services/IP addresses.
- Map all connected assets and tag them for vulnerability tracking.
How We Help
- Supply network architecture assessments, including OT micro-segmentation design.
- Design for, and orchestrate implementation of host-based and network-based threat detection, alerting on anomalies.
- Partner with OT cybersecurity vendors for monitoring firewalls and protocol analysis (Modbus, OPC-UA, MQTT).
6. Supply Chain Disruption
The Challenge
SME manufacturers depend on linchpin suppliers for parts and just-in-time inventory. A breach can halt shipments, damage trust and create contractual penalties.
Self-Help Actions
- Include minimum cybersecurity clauses in contracts.
- Require Cyber Essentials Plus or alternative security assurances from key suppliers.
How We Help
- Conduct supplier security assessments, including reviewing pen test results for vendor software and infrastructure and produce risk assessments based on summary reporting.
- Maintain a live vendor risk register, updated with alerts and compliance status.
- Implement and maintain supply chain threat intelligence and continuous assurance.
7. Data Breach Risk & GDPR Accountability
The Challenge
Personal data on staff, clients, or manufacturing IP can wind up in the public domain. GDPR fines, damages claims, and contractual fallout are real threats.
Self-Help Actions
- Implement strong password policies and auditable access logs.
- Designate a Data Protection Officer (DPO) or external advisor for accountability.
- Map your data types, retention periods and backup processes.
- Maintain a GDPR compliant ROPA.
How We Help
- Provide ROPA, DPIA, and staff training that goes far beyond checkbox compliance.
- Maintain audit logs and incident tracking records, with automated breach reporting readiness.
- Support asset and data discovery efforts across mixed estates.
- Offer data breach preparedness services, including press communications templates and legal referral contacts.
8. Reputational Damage & Lost Business
The Challenge
Reputation matters in manufacturing. A breach in the supply chain (OEM, parts, software) can lose major clients, and it takes time to rebuild trust.
Self-Help Actions
- Publish a simple security statement and privacy notice on your website.
- Maintain basic impact visibility: SSL certs, IDS alerts, firewall posture.
How We Help
- Conduct vulnerability scanning, orchestrating external pen testing, and risk assess and remediate findings.
- Offer reputation support kits, with board‑level board-ready reporting and media communication strategy.
- Provide post-incident recovery assistance, system rebuilds, forensic analysis, public statement drafting.
Final Word on Securing UK Manufacturing in 2025
