Is Your VB6 Application a Hidden Risk? How to Assess It, For Free, Without Exposing a Single Line of Code

From the Innovatix Tech Talk series

“It still works.” That’s what we hear most often from organizations running Visual Basic 6 applications. The order system hums along, users know the screens by heart, and nothing has visibly broken in years. So why change anything?

Here’s the uncomfortable truth: Microsoft ended support for VB6 back in April 2008. We’re now in 2026. That means nearly two decades without security patches, running on a 32-bit, COM-based platform that the rest of the technology world has long since moved past. An application that “works” isn’t the same as an application that’s safe.

In a recent Innovatix Tech Talk, Joe Raffinelli, Director of Technical Solutions, and Nellaiappan, Senior Technical Project Manager, introduced a new AI-assisted tool built to answer one simple question for IT leaders: how risky is my VB6 application, really? The tool is called VB6 Risk Matrix, and it’s free to download.

The Problem: You Can’t Fix What You Can’t See

Most business owners know they have legacy VB6 software. What they don’t know is what that software is exposed to. Is it vulnerable to modern attacks? Does it depend on third-party controls whose vendors disappeared years ago? Would it even run on a new machine?

Because the application keeps running day to day, these risks stay invisible until something goes wrong. VB6 Risk Matrix was designed to be an eye-opener: a clear, evidence-based report that shows exactly where your application stands, so you can make an informed decision about modernization instead of a guess.

How VB6 Risk Matrix Works

Using the tool is simple. You download and install it from the Innovatix website, enter your company and project name, point it at your VB6 project folder, and click Start Analysis. Within moments, it produces a detailed report.

Behind the scenes, the tool ships with a built-in knowledge base of legacy technology: VB6 language patterns, COM objects, ActiveX controls, and a catalog of third-party components from that era. This knowledge base was built using AI, combined with more than a decade of hands-on migration experience from the Innovatix team. The scanning engine maps your source code against that knowledge base and generates its findings.

What the Report Tells You

In the live demo, Nellaiappan ran the tool against a sample VB6 order management system with 510 total files, 260 source files (forms, modules and classes) and roughly 157,000 lines of code. The resulting report covered:

• Executive summary and overall risk rating – The sample application was rated Critical, with critical and high findings, 11 critical CVEs, and additional known vulnerabilities flagged for immediate attention.
• Risk categories – Every finding is classified as Critical (immediate action required), High (significant exposure), Medium (some items should be addressed early) or Low.
• Code statistics – File counts, lines of code and comment density. The sample had just 4.9% commented code, a serious maintainability problem when the original developers are long gone.
• Security findings – For example, inline SQL queries prone to SQL injection, along with clear recommendations such as moving to parameterized queries or stored procedures.
• Platform risks – End-of-life status, no security patches, dependence on 32-bit environments and older operating systems, and oversized files that are hard to maintain.
• Third-party control inventory – Every ActiveX control and DLL in use, how many times it’s referenced (one control in the sample appeared in more than 1,200 places), whether it’s still supported, its criticality, and recommended replacements.
• A clear conclusion – Near-term, short-term and next-step targets, so the report ends with a plan rather than just a list of problems.

With so much detail, where should you start? As Joe noted, focus first on the Critical and High findings. Those are the openings bad actors can exploit most easily.

Zero Code Exposure: Your Source Code Never Leaves Your Machine

The most important question from the session was about privacy. If a tool scans your code, does that code get sent to the internet, or to an AI model for training?

The answer is no. VB6 Risk Matrix operates with zero code exposure. The knowledge base and scanning engine are bundled inside the application and run entirely on your own machine. You can even run it on a standalone, non-internet-connected computer. Nothing is uploaded, shared or used for training.

Why Modernizing VB6 Matters Now

Beyond the report itself, the conversation highlighted why legacy VB6 is a growing business risk:

• Security – These applications were built 15 to 20 years ago, before today’s threat landscape existed. Modern platforms have evolved to 64-bit, highly secured environments; VB6 has not.
• Talent – The developers who built these systems may have retired or moved on, and new graduates simply aren’t learning VB6. When something breaks, fixing it gets harder every year.
• Business continuity – These are often business-critical applications that need to run reliably, every day. Relying on an unsupported platform puts that reliability at risk.

What Does Modernization Look Like?

Timelines – Depending on size, a migration typically ranges from about six months for smaller applications, to around twelve months for mid-sized ones, and up to 18 to 24 months for large enterprise systems. With AI-assisted tooling, Innovatix has cut delivery time on large projects by more than 50% while maintaining quality.

Low-risk rollout – Clients don’t have to “flip a switch.” Two common approaches are an MVP-based rollout, where business-critical modules go live first, often within three to six months, and parallel running, where old and new systems operate side by side with data synchronized between databases. Users transition gradually, can compare results, and the business is never left exposed.

Architecture guided by risk – The risk report is the starting point. Innovatix analyzes it with you in one-on-one sessions, understands your business challenges, identifies replacements for deprecated third-party controls (commercial or open source), and helps you choose a target such as a modern desktop or browser-based application, hosted on-premises or in the cloud. Every risk in the current system is mapped to how it will be eliminated in the new one, giving you a clear modernization roadmap.

A Note on Compliance

One attendee asked whether the tool can certify an application as GDPR, HIPAA or PCI compliant. It can’t, and it isn’t designed to. What it does is surface the risks and code-level issues relevant to how your application handles data, along with recommendations. Formal certification remains the role of your compliance team.

Take the First Step

If your business still depends on a VB6 application, the question isn’t whether it carries risk. It’s how much, and where. VB6 Risk Matrix gives you that answer quickly, privately and at no cost.

Download VB6 Risk Matrix freefrom the Innovatix website, run it on your application, and share the report with our team. We’ll help you interpret the findings and build a modernization plan that protects your business every step of the way.
