Scan Configuration

Additional settings and information related to scans.

Scan Frequency

Scan frequency allows you to configure how often scans will be performed. This setting defaults to a value of once per week. The following options are also available:
  • Day
  • Month
  • Quarter
In addition to configuring the frequency, you may select the time that scans are performed or have them performed at a random time.
To change the scan frequency or time, visit the Target Settings or Domain > Network > Settings page.

AWS Instances

For customers using our AWS integration, it's possible to specify AWS instance IDs for resources that are discovered by the connector. If a target has been assigned an instance ID and the target is an IP address without a hostname, then the target IP will be updated whenever the connector is run. This feature can be useful for AWS assets utilizing dynamic IPs that may change periodically between scans.
To specify an AWS Instance ID, visit the "Advanced Settings" page of the target.

Scan Origins and User Agents

Halo Security uses a number of unique network ranges, user agents, and other identifiers to perform scanning, crawling, and other network related functions. In some cases this information may be useful to identify traffic, add us to the allowlist, or filter out traffic from certain services (such as Google Tag Manager).

Network Ranges

The following network ranges specify the IP addresses where scans are conducted from:
74.82.62.128/26
64.39.96.0/20
139.87.112.0/23
3.18.82.183/32
Additionally, webshots (used to generate previews of the web application) originate from the following IP address: 54.187.125.96

User Agents

For scans that access web applications, as well as the web crawler, Halo Security appends a custom string to the User-Agent header to allow you to distinguish our traffic. This string is vuln_scan_by_trustedsite_com_halo_security. The full User-Agent header will appear like the following:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_10_3; en-us) AppleWebKit/600.6.3 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/600.6.3 vuln_scan_by_trustedsite_com_halo_security
