We are delighted to announce the release of NetAnalysis® v4.0 — a major update that brings powerful new features, enhanced performance, and a refined user interface, all designed to help forensic examiners work faster and more efficiently. This release marks a significant step forward in digital forensic analysis, with a suite of advanced tools to support the evolving landscape of browser-based evidence.
Whether you're examining thousands of cached images, deep-diving into client-side storage, or unravelling the structure of complex URLs, NetAnalysis® v4.0 gives you the tools you need to uncover the truth with clarity and precision.
NetAnalysis® now includes a Gallery Viewer — a new thumbnail-based image viewer that makes it easy to browse, review, and manage cached images, preview thumbnails, FavIcons and more. With support for JPEG, PNG, SVG, WebP, GIF, BMP, and ICO formats, this grid-style viewer allows you to:
View all recovered images in one place
Tag, bookmark, and filter relevant images
Export selected images for further investigation
Ideal for quickly assessing visual content and identifying key artefacts.
The new Storage Examiner Panel brings deep analysis capabilities for Local Storage, Session Storage, and IndexedDB entries. With a structured view of client-side storage, you can:
Search and filter JSON key-value pairs
Decode and examine deeply nested data structures
Export selected data to JSON, CSV, or text formats
This is a significant enhancement for anyone investigating modern web applications and single-page apps.
JSON is everywhere — and now, so is support for examining it. The new JSON Examiner Form, accessible via the Tools menu, allows you to:
View and format unstructured JSON files
Search and filter content
Expand and collapse nested structures with syntax highlighting
Perfect for analysing preference files, configuration settings, and client-side storage.
This release also includes a range of UI enhancements to improve workflow and usability:
The Filter menu now includes new predefined date filters (e.g. "Last 90 Days") and quick access to common Entry Types like Cookies, Downloads, and Search Terms.
Numerous improvements to layout, panel management, and column resizing
Updated icons and visual polish for an even more intuitive experience
NetAnalysis® v4.0 includes updated support for hundreds of browser versions across Chrome, Firefox, Edge, Safari, Opera, and more — including both desktop and mobile platforms. This ensures continued compatibility with the latest releases and artefact formats.
NetAnalysis® v4.0 is a major milestone in forensic browser analysis — delivering both powerful new functionality and workflow improvements that make your job easier, faster, and more accurate. We’d like to thank our customers and partners for their continued support and feedback.
As always, we look forward to hearing how these new features help your investigations. If you have any questions or suggestions, please get in touch with our support team.
