London, April 30, 2026 – Meterian, the UK-based open-source security company, today announced the launch of HEIDI, a free security plugin for Integrated Development Environments (IDEs).
Available on Visual Studio Code and the JetBrains IDEs, HEIDI enables developers to detect and fix open-source vulnerabilities directly inside their coding environment, making security part of everyday development rather than an afterthought.
Within a month of deploying on Visual Studio Marketplace, the free plugin has seen nearly 5,000 installs from developers. This level of pre-launch engagement reflects the critical demand for such a project.
With software supply chain attacks on the rise and open-source dependencies powering 80–90% of modern applications, the risks of leaving vulnerabilities unchecked are increasing. Yet most security scanning still happens late in the process, inside CI/CD pipelines or after release.
Open-source software developer Roberto Franchini of ArcadeDB said, “It is the reality of using AI for development that LLMs do not know about vulnerabilities exposed today. HEIDI serves as an important live security layer by comparing AI proposals with current threat intelligence information. This means that we can take advantage of AI without incurring the security debt from old data sets.” By shifting security into the IDE, HEIDI allows developers to identify and fix issues before code ever leaves their machine.
“Developers spend most of their time coding inside IDEs. HEIDI meets them where they work, ensuring security isn’t an extra step but part of the process itself,” said Bruno Bossola, CTO and co-founder of Meterian. “This is how we reduce security debt, cut patching costs, and prevent vulnerable code from reaching production.”
HEIDI also extends its capabilities through a built-in Model Context Protocol (MCP) server that connects directly with AI coding assistants. Unlike most AI tools, which depend on static pre-trained knowledge, HEIDI brings real-time vulnerability intelligence into the developer’s AI workflow, including tools such as Codex, Claude, GitHub Copilot, Cursor, Windsurf, and other MCP-compatible assistants.
Key Features of HEIDI
Automatic vulnerability scanning of direct and transitive dependencies.
One-click fixes that let developers apply remediation instantly.
Lightweight reporting with actionable insights inside the IDE.
No source code transferred — only manifest files are scanned, protecting IP.
Language support: Java, .NET, NodeJS, Python, PHP, Ruby, Rust, Go.
AI assistant integration via built-in MCP server with real-time vulnerability intelligence.
The urgency is clear from recent concerns around Anthropic’s Claude Mythos. Anthropic said Mythos Preview could identify and exploit zero-day vulnerabilities in major operating systems and browsers.
HEIDI is built for the defensive side of that shift, giving AI coding assistants current, project-specific dependency risk context so developers can spot vulnerable packages, understand the risk, and apply safer upgrade paths before code ships.
A Seamless Path to Enterprise Security
The free HEIDI plugin delivers immediate value to developers, while offering a natural pathway to Meterian’s enterprise Software Composition Analysis (SCA) suite, which provides advanced CI/CD integrations, SBOM management, custom security policies, and comprehensive reporting.
Meterian is engaging open-source communities, OWASP chapters, and developer forums to build grassroots traction.
Why It Matters
According to IBM’s 2025 Data Breach Report, the average breach costs $4.4 million — but vulnerabilities discovered late in the development cycle are far more expensive to fix. By embedding checks early in the software development lifecycle, HEIDI empowers developers to find, fix, and ship securely.

UK manufacturing is becoming more exposed to cyber disruption as factories rely on connected systems, industrial software, cloud platforms, and third-party suppliers.
Ransomware and denial-of-service attacks are among the most damaging threats. They can stop production, delay shipments, disrupt supply chains, and create direct financial losses.
For manufacturers, cyber risk now reaches far beyond IT systems. It affects uptime, safety, fulfilment, customer commitments, and business continuity.
UK Manufacturers Are Facing a Higher Level of Cyber Disruption
A 2026 ESET survey found that 78% of UK manufacturers experienced a cyber incident in the past year.
Among affected firms, 95% reported direct business impact, 53% suffered financial loss, 44% faced supply chain disruption, and 39% missed customer or supplier commitments. Some incidents caused losses above £250,000.
The wider UK picture is also concerning. The UK government’s Cyber Security Breaches Survey 2025 found that 43% of UK businesses experienced a cyber breach or attack in the previous 12 months. The figure rose to 67% for medium businesses and 74% for large businesses.
Manufacturing is especially exposed because downtime has an immediate cost. A locked system or unavailable application can quickly become a halted line, a missed order, or a broken supplier commitment.
Ransomware Remains the Primary Cyber Threat
Ransomware remains one of the most serious threats to UK organisations. The National Crime Agency describes ransomware deployment as the UK’s greatest cyber serious and organised crime threat, with risks to Critical National Infrastructure and national security.
A ransomware attack usually blocks access to systems or data until a payment is demanded. Modern ransomware campaigns often go further. Attackers may steal data, threaten to publish intellectual property, pressure suppliers, and use public disruption to force negotiations.
This is dangerous for manufacturers because production depends on availability. If planning systems, engineering files, logistics platforms, or connected production environments become unavailable, the impact can move quickly from digital systems into physical operations.
The Jaguar Land Rover cyber incident showed how severe that impact can become.
The Cyber Monitoring Centre categorised the 2025 JLR incident as a Category 3 systemic event, estimating a £1.9 billion UK financial impact and effects across more than 5,000 UK organisations.
Production lines were halted for several weeks, and suppliers faced cancelled or delayed orders. That case underlines the central point: a major cyber incident in manufacturing can become a supply chain event.
DDoS Attacks Can Stop Access to Critical Services
Denial-of-service attacks create disruption by overwhelming websites, applications, or networks. The Information Commissioner’s Office describes a DoS attack as an attempt to stop normal system function by overloading it and creating a virtual “traffic jam.”
In a distributed denial-of-service attack, the attacker uses many connected devices to flood the target from multiple points.
For manufacturers, DDoS risk is not limited to public websites. It can affect customer portals, supplier platforms, remote access systems, cloud dashboards, and connected industrial services.
UK government data shows denial-of-service attacks affected 15% of large businesses that experienced a cyber breach or attack, compared with 5% of businesses overall.
The practical impact is simple. If key systems are unavailable, production planning slows down, orders cannot be processed, suppliers lose visibility, and internal teams are forced into manual workarounds.
Why Manufacturing Is Especially Vulnerable
Manufacturing has a different risk profile from many office-based sectors.
Many firms still run legacy operational technology alongside newer digital systems. Older systems are often difficult to patch, hard to monitor, and expensive to replace. As IT and OT environments become more connected, weaknesses in one area can create exposure in another.
Manufacturers also depend on complex supplier networks. A vulnerability in a third-party system, open-source component, software update, or connected service can create risk across several organisations.
This makes software supply chain security critical. Modern manufacturing companies often use internal applications, vendor platforms, cloud services, containerised workloads, and open-source libraries.
Open source software makes up an estimated 80–90% of software application code, which means dependency risk is now part of operational resilience.
Attackers understand this. They do not always need to attack the factory floor directly. They can exploit exposed software, vulnerable dependencies, weak supplier access, or outdated components that sit inside the wider digital environment.
The Preparedness Gap
Many organisations still lack the right level of preparation.
The UK government’s Cyber Security Breaches Survey 2025 found that only 32% of businesses had a business continuity plan covering cyber security. For micro businesses, the figure was 27%.
That gap matters because prevention alone is not enough. Manufacturers need to know what software they use, which components are vulnerable, which systems are exposed, and how quickly they can recover when something goes wrong.
A strong cyber resilience plan should include:
Tested backup and recovery processes
Network segmentation between IT and OT systems
Regular vulnerability assessment
Software Bill of Materials visibility
Continuous monitoring of open-source components
Incident response planning
Clear supplier security expectations
Developer workflows that catch risks before release
Cyber Essentials, penetration testing, and annual reviews all have value. However, they cannot replace continuous visibility. New vulnerabilities are disclosed every day. A system that was safe last month may be exposed today.
Where Meterian and Cybersecurity Services Fit
Meterian helps organisations reduce software supply chain risk by giving security and engineering teams clearer visibility into open-source dependencies, vulnerable components, and remediation priorities.
Meterian-X provides continuous review of open-source libraries, risk prioritisation, actionable reporting, policy controls, and alerts that help teams fix issues earlier in the software development lifecycle.
For manufacturing businesses, this matters because software now supports production planning, supplier coordination, logistics, customer delivery, connected devices, and internal operations.
Meterian can help teams:
Identify vulnerable open-source components
Monitor dependencies continuously
Prioritise the most urgent risks
Generate clear reports for developers and security teams
Support governance and compliance workflows
Integrate security checks into DevSecOps pipelines
Scan application codebases and container images
Meterian’s HEIDI plugin also brings open-source vulnerability detection directly into the IDE. It helps developers catch and resolve vulnerable dependencies during the coding phase, before issues reach production systems.
That early visibility matters. The later a vulnerability is found, the more expensive and disruptive it becomes to fix.
Want to understand where open-source vulnerabilities may be hiding in your software supply chain? Use Meterian to scan your codebase, monitor dependencies continuously, and give your teams clear remediation paths before risk reaches production.
Building Cyber Resilience in UK Manufacturing
UK manufacturers cannot remove every cyber risk. They can reduce exposure, improve visibility, and make disruption less damaging.
That starts with treating software supply chain security as part of operational resilience. Manufacturers need to know which components they rely on, where vulnerabilities exist, and which fixes should come first.
The most resilient organisations will be those that connect security with engineering, operations, procurement, and risk management. Continuous scanning, dependency visibility, and fast remediation should become standard controls for any software-driven manufacturing environment.
Conclusion
Ransomware and DDoS attacks are now serious operational risks for UK manufacturing.
The sector depends on connected software, complex suppliers, and production systems that cannot afford prolonged downtime. Recent incidents show that a cyberattack can stop production, delay orders, expose sensitive data, and affect thousands of connected organisations.
Manufacturers need more than periodic testing and basic compliance. They need continuous visibility across the software systems that support their operations.
Meterian helps manufacturers strengthen that visibility by scanning codebases, monitoring open-source dependencies, prioritising vulnerabilities, and supporting DevSecOps workflows.
We’re already into the second half of 2026, and it’s worth pausing for a second. Not to recap headlines, but to understand what actually changed in terms of security.
Spoiler alert…. A lot.
Because 2025 wasn’t just another year of breaches. The scale was larger, and the impact was more visible.
The attack on Jaguar Land Rover brought that into focus. Production stopped for months. The losses were estimated at £1.9 billion. The disruption moved straight into operations and revenue.
In the education sector, Kido International faced a ransomware incident that exposed personal data linked to thousands of children and staff. The impact here sat around safeguarding and trust.
Retail saw a similar strain. The ShinyHunters group claimed breaches across multiple brands, including Marks & Spencer. Some platforms lost the ability to trade online during the disruption.
Alongside these cases, a large pool of over 16 billion credentials circulated across criminal forums. Those datasets fed ongoing account takeover attempts throughout the year.
None of this felt isolated. The same weaknesses appeared again and again.
Constant Pressure on Infrastructure
Attacks moved closer to systems that support daily life.
The incident in Poland’s energy sector showed how attackers can move across IT and operational environments. That overlap creates a different kind of exposure.
In the UK, water utilities faced continued pressure from ransomware incidents. These systems often rely on older industrial controls with limited visibility.
At the consumer level, compromised IoT devices formed large botnets. Devices that sit in homes became part of wider attack infrastructure without the user being aware.
The surface area kept expanding.
The Supply Chain Problem is Getting Bigger
Across these incidents, the supply chain kept appearing in the background.
Attackers focused on software providers, cloud platforms, and third-party tools. Access at that level opens the door to many organisations at once.
This approach scales efficiently. One weakness can affect a large number of systems downstream.
For most organisations, this sits outside direct control. That makes it harder to track and harder to manage.
What’s Changing in 2026? A lot
The direction for the coming year is already visible.
Attack workflows are becoming faster. Automation plays a larger role. AI is being used to scan systems, prepare phishing content, and identify weak points.
The targets remain consistent. Local government systems, supply chains, and infrastructure continue to attract attention.
These environments often operate with limited resources and older technology. That combination creates exposure that is difficult to close quickly.
The Open Source Reality
Most systems depend on open source components.
That dependency runs deep. Many components sit several layers down, out of sight during routine checks.
Over time, vulnerabilities build up in those layers. Without active monitoring, they remain unnoticed.
Periodic reviews miss changes that happen between audits. New vulnerabilities appear regularly, and attackers move quickly once they are public.
Continuous monitoring becomes part of day-to-day security, rather than an occasional task.
The events of 2025 point to a clear shift in approach.
Security needs to keep pace with how quickly vulnerabilities appear and spread. That requires visibility into dependencies and a way to respond without delay.
The focus moves toward shorter response times and better awareness of what sits inside each system.
Small gaps tend to expand quickly when left unattended.
Closing Thought
The past year showed how cyber incidents now reach into operations, services, and public systems.
The same patterns are already carrying into 2026.
The difference will come from how quickly organisations detect and respond to what is already present in their environment.
What can you do? Start with visibility. Continuous monitoring of your open source components is non-negotiable.
