Product Overview #
We’ve introduced SanerNow Cyber Hygiene Score – a new feature that assigns a score to Organizations, Accounts, and devices within the SanerNow ecosystem.
Cybersecurity hygiene can be defined as a set of practices an organization adapts to keep its network, assets, and users safe from cyberattacks.
A Cyber Hygiene Score is the quantification of the total attack surface of a device that includes Common Vulnerabilities and Exposures(CVEs), Common Configuration Enumeration(CCEs), Missing Patches, and Posture Anomalies.
The Cyber Hygiene Score clearly shows how secure the devices are within your Organization – and helps you identify the steps needed to perform to improve your Organization’s security posture.
Types of Scores in CHS #
Raw Score #
SanerNow computes the raw score by giving an equal weightage of 25% each to CVEs, CCEs, Missing Patches, and Posture Anomalies, leading to four subscores being computed. A raw score is the sum of the four subscores and can be customized. The higher the raw score of a device, the less secure it is.
Global Score #
Global score is a normalized raw score that ranges from 0-100. The higher the global score a device has, the more secure it is. Each Account in an Organization has a different score, and we can compare the Global Score of a device from one Account to another device from another Account.
Local Score #
The Local score is computed as another normalized raw score that indicates where the device stands in an Account. The safest device in an Account will score 100, while the least safe device gets a 0. The main intention behind computing Local Score is to find the best device in the Account. You can compare the Local Score of machines within the Account.
Cyber Hygiene Score #
The Cyber Hygiene Score of a device is the weighted average of a device’s Global Score and Local Score. The default weightage of 80% Global Score and 20% Local Score is considered during the computation of the Cyber Hygiene Score.
Patched Account Score #
The Patched Account Score is an ideal account score for an Account. It is achieved when all the missing patches are applied, vulnerabilities patched, and Posture Anomalies and CCEs remediated. The Patched Risk Score is an ideal Risk Score that every Account should strive to achieve by leveraging various SanerNow tools. However, while calculating the Patched Account Score, we consider that you’ve been getting vulnerabilities and misconfigurations and will continue to get vulnerabilities in the future. SanerNow’s Machine Learning algorithm computes the Patched Account Score by training how your score has been in the past and how it might be in the future.
Account Score #
The Account Score is the average of the Risk Score of the devices in an Account.
Organization Score #
The Organization Score is the weighted average of the scores of all the Accounts under the Organization. At the same time, while computing the Organization Score, the number of devices in the Account is the weight.

CHS Organization Dashboard #
CHS Organization Dashboard gives detailed information about the Accounts that belong to the Organization you selected. Let’s look at each of these grids and the information provided by them.
Cyber Hygiene Score #
The Cyber Hygiene Score grid displays the CHS Score for the Organization. It is the weighted average of the scores of all the Accounts in an Organization to which the user has access. CHS Score is categorized into the following levels:
| CHS Score Category | Range | Color Code |
| Low | 0 – 39 | Red |
| Medium | 40 – 79 | Yellow |
| High | 80 – 100 | Green |
You can refer to the Types of Scores in CHS section to learn more about how scores are computed.
Cyber Hygiene Trend #
The Cyber Hygiene Trend graph visually represents the change in Organization score over 30 days. You can download the Cyber Hygiene Trend report in a CSV format. Click on the icon on the top right of the Cyber Hygiene Trend grid. A pop-up message will appear, asking you to confirm the location where you want the file to be saved.
Accounts Table #
Accounts Table displays the following information.
- Account Name – This column displays all the Accounts part of the selected Organization.
- Score – This column displays the CHS Score for individual Accounts.
- Devices – This column shows the total number of devices in an Account.
- Severity – This column shows the severity category for the devices
- Last Scan Date – This column displays the date and time of the most recent CHS Scan done on the Account.
You can download the information presented in the Accounts table in a CSV format. Click the 
icon to download and save the file on your machine.
Configure Weightage #
Each module, namely Vulnerabilities, Misconfigurations, Missing Patches, and Posture Anomalies contributes to your sub-score. Depending on your IT infrastructure requirements, you can prioritize how much each module will contribute to your subscore. You can configure the weightage for the Accounts in the Organization. You can do it manually or use the Auto-adjust feature.
Click the gear icon 
on the right side of the CHS homepage. A pop-up window appears, allowing you to enter the weightage manually. However, ensure that the total sum of the weightages doesn’t exceed 100.
Also, you can use the Auto-adjust feature to configure the weightage for the Accounts. Auto-adjust feature allows you to set the weightage by using the slider.
Click the Save button to save the newly specified weightages.
| Note You can configure weightages for individual Accounts. However, you can also configure weightages for all the Accounts in an Organization by checking the Select All checkbox. |
Navigation Help #
SanerNow CHS has built-in Navigation help. Click on the icon to access the navigation help.
Click the Next button to navigate to the next slide. The navigation help gives you a brief tour of the CHS Organization dashboard.
CHS Account Dashboard #
CHS Account Dashboard provides detailed information about the devices in the Account. Let’s take a look at each of the grids and the information provided by them.
Cyber Hygiene Score #
The Cyber Hygiene Score grid displays the CHS Score for the Account. A metered graph represents the latest overall cyber hygiene score of the Account. CHS Score is categorized into the following levels:
| CHS Score Category | Range | Color Code |
| High | 0 – 39 | Green |
| Medium | 40 – 79 | Yellow |
| Low | 80 – 100 | Red |
Contributors #
The Contributors grid displays the contribution of each of the four SanerNow modules (VM, PM, CM, and PA) towards the CHS Score of the Account. You get a clear view of the factors – CVEs, CCEs, Missing Patches, and PAs that are bringing down the CHS score of the Account.
You can download the information presented in the Contributors graph in a CSV format. Click on the icon to download and save the file on your machine.
Cyber Hygiene Trend #
The Cyber Hygiene Trend graph shows the trend in the Cyber Hygiene Score over the past 30 days. The trending graph gives a visual representation of change in score over time, helping the user to analyze the difference in the count of vulnerabilities and other risks that exist in an account. The CHS trending graph also helps to examine the impact of remediation actions performed on the Account.
Similarly, the Cyber Hygiene Trend graph shows the score prediction for the next day, assuming that the user undertakes all the recommended remediation actions against detected vulnerabilities and risks. The difference between the predicted and actual scores of an Account reflects the impact of remedial actions performed by the user.
You can download the information presented in the Cyber Hygiene Trend graph in a CSV format. Click on the icon to download and save the file on your machine.
