NS8 Protect Performance and Reputation Monitors

Description and configuration of the NS8 Protect Performance Monitor functions.

After clicking on the Reputation Monitors card in NS8 Protect, you will be taken to a screen where the performance and reputation monitors can be viewed and adjusted.

The slider buttons on the left side of the screen will turn each monitor on and off. Normally all monitors will be enabled; however, you may wish to turn a monitor off during website updates or while resolving a related issue.

Performance Monitor Control

The top half of this screen is dedicated to monitor status and control. The green "Run Test" button will let you run a monitor and return an immediate test result.

Important: Click on the green Edit button to control the contacts for each monitor.

This will open the Monitor Preferences Screen. A contact is established by default when you install NS8 Protect. You may want to set this to a specific contact in your company to make sure performance notifications do not get missed. Additional contacts can be added using the Monitor Contact Screen.

Testing and Editing Monitors

There are two buttons next to each monitor. The first is the "Run Test" button, which runs each test and returns an immediate result. The "Edit" button will allows to edit the settings and contact settings for each monitor.

The five performance monitors are:

Certificate Validity

The certificate monitor checks the validity of certificates and alerts you to the following before your certificates expire:

  • Whether the certificate is accessible
  • Whether the certificate matches the domain
  • Whether the certificate is expired
  • Whether the certificate is valid
  • Whether the certificate has a revoked root CA
  • Whether the certificate supports a cipher that has been deprecated

Domain Blocklist

This monitor checks if your domain has been blocklisted, using the most reputable blocklists. This occurs if a certain amount of complaints are received by the listing services. Website domains can be blocklisted by appearing on emails that are considered spam.

However, you do not actually need to be engaged in spam to get listed. Domains are listed based on algorithms that can trap non-spammers unknowingly.

If you are blocklisted, most of your emails will no longer be delivered.

Global Performance

This monitors global load times and satisfaction levels from real users and find issues based on real user experiences. It also optimizes your site's performance based on dozens of attributes, including location and device. This is enabled by placing a JavaScript snippet on your pages.

We monitor the following metrics for issues:

  • DNS Time: The average amount of time DNS resolution takes.
  • Response Time: The average amount of time the web server takes to begin the response to the user.
  • Interactive Time: The average amount of time in milliseconds before the page becomes interactive.

Once implemented, there is sophisticated reporting available on performance issues that can be segmented by:

  • Geolocation
  • Browser
  • Platform
  • Device
  • Time of Day
    and many other attributes. You can even compare traffic levels to performance issues to determine if you need extra capacity.

Google Safe Browsing

The Google Safe Browsing monitor checks if your site has been flagged by the Google Safe Browsing service for hosting malware or being a phishing site.

Google provides this service in order to warn users to websites that the site is unsafe. It is also used by security systems to prevent users from browsing listed sites.

If you are listed, this indicates that your site has been compromised and/or infected with malware.

Website Content Match

This monitor utilizes our global network of monitoring stations to make sure your website is available and responsive from around the world. The website monitor continuously checks your site for the following issues:

  • If the site is up or down
  • If the site loads within a time that you set
  • If DNS is responding

Match Phrase testing look for keywords or phrases you enter every time your page is tested. This will help to make sure that the page's content has not been hijacked or edited nefariously. For example, if your site sells coffee mugs, you may want the monitor to search for mugs.
How long it takes to resolve DNS, connect to the site, and download the HTML

  • For secure sites, whether the certificate matches the domain
  • For secure sites, whether the certificate is expired
  • For secure sites, whether the certificate is valid
  • If the URL redirects, that the target exists
