All Release Notes Reporter for Sophos Web Appliance 4.5.0.1 (2026-08-27)

This build renumbers Fastvue Reporter to 4.5 and unifies versioning across all Fastvue Reporter brands. Alongside the version change, it brings a refreshed user interface, a significant round of Microsoft 365 email and messaging work, and major improvements to how large reports are processed.

Unified Version Numbering

Fastvue Reporter now uses a unified 4.5.x.x version scheme across every Fastvue Reporter brand (Reporter for Barracuda, Cisco, ContentKeeper, Fortinet, Palo Alto Networks, SonicWall, Sophos, WatchGuard, and even the old Microsoft TMG – yes, some folks still use it!). Previously each brand carried its own major version, but as all Fastvue Reporter products share the same underlying codebase, it made sense to synchronise them on the new 4.5 convention. From this release onwards all brands share the same version number, and 4.5 reflects the scale of recent work including the Microsoft 365 email and messaging integration, the interface rework, and report generation optimisations.

Interface Refresh

Fastvue Reporter has received a minor user interface glow-up. Every icon in Fastvue Reporter has been replaced with modern vector icons, and buttons and colours have been brought into line across the whole product. The result is a cleaner, more consistent interface with improved interactions.

Large Reports

• Long date ranges: Reports covering long date ranges are now processed in smaller chunks rather than all at once, so reports spanning multiple months, and even years, complete successfully on datasets that would previously run out of memory partway through.
• Report size warnings: If a report is too large to complete on your server, Fastvue Reporter now tells you straight away and suggests shortening the date range or allocating more memory, instead of running for a long time and then failing.
• Browsing Time: Optimised the Browsing Time calculation, which could cause excessive memory usage when running very large reports.

Dashboard and Reports

• Dashboard drilldowns: You can now choose which report to drill down into from the Dashboard. Previously, drilling down from a Dashboard widget always launched the All Usage Report. You can now select the report you actually want, with the widget’s context carried through as filters, just like you’ve always been able to do from within Reports.
• Markdown export: Reports can now be exported to Markdown, in addition to PDF and CSV.
• Safeguarding Report: The email card sometimes displayed the wrong ‘From’ address. If the username portion of an external email address matched the username portion of an internal email address, the internal email address would be shown as the ‘From’ address in the email card, while the correct address appeared when viewing the full email. The card now shows the correct sender.
• PDF exports: Fixed formatting issues in the YouTube video card when exported to PDF.

Message Context Dialog

The Message Context dialog, which displays the content of an email, chat conversation, YouTube video or web browsing session from the Safeguarding Report, has received multiple improvements.

• Export: The content of the Message Context dialog can be exported directly to PDF, Markdown, or CSV (for Sites/URLs).
• Images: Images attached to or embedded in emails and messages now display correctly when viewing the full message context.
• Draft and deleted emails: When viewing an email, the email header section now indicates if the email is a draft or has been deleted.
• Full context: Fixed an issue that could prevent the full context of an email or chat message from being retrieved.
• View Sites: In the ‘View Sites’ context dialog, the times shown were incorrectly offset by the local timezone. They now display correctly.
• Keyword highlighting: The Message Context dialog now highlights the matched keyword correctly.

Microsoft 365 Email and Messaging

• Import speed: Importing email and chat messages from Microsoft 365 is now substantially faster.
• Import statistics: Corrected the ‘Processed’ message import statistic to indicate the number of messages examined rather than the number of mailboxes and users checked.
• Whole-word matching: When importing emails, formatting was being stripped in a way that joined words together across line breaks, so whole-word keyword matches could be missed and keyword highlighting in the Message Context dialog was also affected. These issues have been resolved.
• Alert and report emails: Fastvue Reporter’s own alert and report emails are now reliably excluded from Microsoft 365 email imports.
• Filters: Message Sender was listed twice in the filter options.

Alerts

• Keyword groups: Alerts configured against custom keyword groups now trigger correctly.
• Browsing Time: Browsing Time is available again as an alert criterion, which also re-enables the alert threshold options that depend on it.

Stability and Security

• Log4j: Log4j has been updated to 2.26.1, addressing CVE-2026-49844.
• Database maintenance: Routine database maintenance could run out of memory on very large data stores. This has been resolved.

Licensing

Fastvue Reporter now allows you to add up to twice your licensed source count. Firewalls deployed as HA pairs send logs from two hosts, which previously counted as two sources against your licence and could put you over your limit. The additional headroom means HA pairs no longer require a licence upgrade.

Other Fixes

• Directory sources: A Default Domain Controller directory source is now only created on first run, rather than being recreated on every startup after being deleted.
• Demo data: Demo data was generating packet counts orders of magnitude too high across all brands.
