eSentire MVS – External Scan Scheduling & Configuration Review
Purpose
This guide outlines the required actions after receiving notification that your Managed Vulnerability Service (MVS) cloud container has been provisioned and your first external scan is scheduled.
1st Scheduled External Scan Details
(GCP WPress VM Website)
Scan Type: External Vulnerability Scan
Date: Saturday, February 14, 2026
Time: 06:00 EST
Step 1: Acknowledge the Scan Schedule
Action Required
Review the scan date and time.
Confirm the schedule with your internal team.
Reply to the eSentire contact to acknowledge approval.
If the scheduled time does not work:
Notify eSentire.
Request rescheduling to the following week or a preferred date.
✅ Scans will proceed as scheduled unless changes are requested.
Step 2: Review Configuration (XLSX Worksheet)
Action Required
Open the referenced configuration XLSX file.
Confirm:
Target public IP addresses
Scan scope
Approved assets
Ensure no incorrect or unauthorized assets are included.
Step 3: Verify Firewall and Network Settings
To prevent scan disruption, confirm the following:
1. Allow Tenable Cloud Scanner IP Ranges
Ensure these IP ranges are not blocked or deny-listed:
3.98.92.0/25
35.182.14.64/26
⚠ Important:
Do not create a firewall bypass rule.
Simply confirm traffic from these ranges is not automatically dropped.
2. ICMP (Ping) Handling
If your firewall blocks ICMP by default:
Allow ICMP (ping) from the Tenable scanner IP ranges.
This ensures accurate host discovery during scanning.
Step 4: Notify Third-Party Hosting Providers (If Applicable)
If any scanned public IPs are:
Hosted by third parties
Managed by external vendors
Protected by upstream security providers
You must:
Notify them of the scheduled scanning activity.
Confirm approval for vulnerability scanning.
Ensure scanning traffic will not be blocked.
⚠ Failure to notify third parties may result in blocked scans or service alerts.
Step 5: After the First Scan
