How to turn a vulnerability scan export into a client-ready report

The short version:

• Export the scanner's complete machine-readable format (XML, JSON or full CSV), never its PDF.
• Check scope, scan date and credential status before you write a word.
• Group findings into remediation actions and rank them by known exploitation first.
• Lead the report with decisions; move the raw detail to an appendix.

Step 1: export the right file

Every scanner offers a polished PDF and a raw data export. The PDF is designed to be read, so it summarizes; fields such as CVE lists, plugin output or detection details are often trimmed. The raw export keeps everything, which is what you need to build a report you can defend.

The export to use per scanner

Microsoft Defender Vulnerability Management and ConnectSecure have no export file to upload. Connect them to Varaxon Scan Hub directly instead, which keeps the complete record including software inventory. Defender needs Microsoft Defender for Endpoint Plan 2, Defender Vulnerability Management or Defender for Servers.

Step 2: check what the scan could see

Before reading findings, confirm the scan's boundary. A report built on a partial scan should say so on the first page.

• Scope. Compare the hosts in the export with the client's asset list. A missing server is a gap, not a pass.
• Date and feed age. Record when the scan ran and how current the scanner's checks were.
• Credentials. Note which hosts were scanned with working credentials. A failed login quietly drops a host to a network-only view; see credentialed vs non-credentialed scans.
• Filters. Some exports apply filters at download time, such as Greenbone's Quality of Detection threshold. Make sure nothing was hidden by accident.

Step 3: group findings into actions

Clients do not fix findings; they perform actions. Forty Windows findings across twenty laptops usually collapse into one action: apply the current cumulative update. Group by the remediation, then list the affected hosts under it. This turns a 600-row export into a list of 15 or 20 things to do, which is a list a client can actually schedule.

Keep the evidence attached When you group, keep each action linked to the scanner evidence behind it: the detected version, the plugin or check output, the CVE list. That is what lets a technician verify the fix and lets you answer the client's "how do you know?"

Step 4: put the actions in order

Rank actions by the strongest evidence of real-world risk first. A defensible order:

1. Anything in the CISA Known Exploited Vulnerabilities (KEV) catalog, with known ransomware use at the very top.
2. Critical findings (CVSS 9.0 or above) without a KEV match, especially on internet-facing systems.
3. Other findings with a CVE and meaningful severity, ordered by severity and EPSS.
4. Findings without a CVE that still matter, such as end-of-life software or weak remote access configuration.
5. Low and informational items, as context.

The reasoning behind this order is in CVSS vs EPSS vs CISA KEV. Varaxon Scan Hub applies exactly these six bands with deterministic code, so two reports from the same export always agree.

Step 5: write for the person who decides

The first page is for the business owner or IT manager. Say what was scanned, the three to five actions that matter most, what they protect against and roughly what each involves. Leave raw counts of Highs and Mediums off this page: they alarm without informing.

After the summary come the scope and method, the full prioritized action list with owners and target dates, and a technical appendix with per-host detail. The report template guide lists every section and what goes in it.

Step 6: hand over the work, then track it

A report is only useful if the actions become tickets someone closes. Agree target dates with the client (the remediation SLA guide has a starting matrix), create the tickets, and compare the next scan against this one so the client sees what was fixed and what is still open.

Varaxon Scan Hub covers steps 2 to 6 from the uploaded export: it checks coverage, groups and ranks the actions, writes the report, creates reviewed HaloPSA or ConnectWise PSA tickets and tracks each client between scans. See the sample reports, or try it on your own export with the free pre-flight check.

Common questions

Should I send the scanner's own PDF report to a client?

It is better as an appendix than as the report. Scanner PDFs are organized by finding and host, not by the actions the client needs to take, and some omit fields the raw export contains.

How long should a vulnerability report for a small business be?

Keep the decision part to one or two pages: a summary and the prioritized action list. The technical appendix can be as long as the scan requires, because only technicians read it.

I'm building Varaxon Scan Hub. It turns exports from Nessus, Greenbone/OpenVAS, Qualys, Rapid7, Nuclei, Burp, Defender and other network, host and web scanners into clear, client-ready reports, and can open HaloPSA or ConnectWise tickets after you review them. Your first three reports are free, and a free pre-flight check shows what it can read from your export first.
