nessus failed to export scan report to pdf after authorized scan

TL;DR

PDF export failing after a scan usually means the report generator ran out of memory or disk on a very large report, or the Nessus service's report components are damaged. Prove the data is safe by exporting CSV or HTML first, then produce the PDF in filtered sections, or repair the install, so the client deliverable does not depend on one fragile render.

Use this when

• Export to PDF errors, hangs, or produces a zero-byte file for a completed authorized scan.
• Smaller scan reports export to PDF fine on the same Nessus install.

Not for this skill when

• The scan itself is still running or queued. Wait for completion; partial PDFs mislead.
• The requirement is actually a machine-readable findings file. Export CSV or the native format instead of fighting the PDF path.

Steps

1. Protect the data first: export the same completed scan to CSV and to HTML and confirm both contain the findings. Verify: Verify: the findings exist outside the PDF path, so the engagement data is safe whatever happens next.
2. Check free disk on the Nessus host and the size of the scan; very large reports commonly fail on space or memory during rendering. Verify: Verify: free space comfortably exceeds the report size, or you have found the constraint.
3. Filter the PDF export to one host group or severity band at a time, producing section PDFs that each render successfully. Verify: Verify: every section PDF opens and together they cover the full scan.
4. If even a tiny report fails to PDF, repair or update the Nessus install, since its report components are likely damaged, then retest with the small report. Verify: Verify: the small report exports cleanly after the repair.
5. Assemble the deliverable, note the feed date and scan name on the cover information, and keep the CSV export with it as the authoritative findings list. Verify: Verify: the delivered package opens, is complete, and matches the CSV counts.

Why it happens

PDF is a rendered document built from the whole result set at once, so it is the most resource-hungry export and the first to fail on big scans or tight hosts. The findings database itself is usually fine, which is why other formats succeed and why sectioned rendering works around the peak load without touching the scan data.

Edge cases / pitfalls

• A PDF that renders but truncates tables is a silent integrity risk; cross-check finding counts against the CSV before delivery.
• Client deliverables may need remediation detail the executive PDF trims; agree the format set in the statement of work, not at export time.
• Keep the native scan export archived so the report can be regenerated after the scanner is rebuilt.
