ServiceNow App v 1.2 strengthens our ticketing integration 

The Nucleus ServiceNow app interface

Our integration with ServiceNow ITSM just improved: We’re excited to announce the release of version 1.2.0 of our ServiceNow App!      

Highlights include a new “Manage Projects” menu in the ServiceNow App, which allows customers to integrate and easily configure mapping for each action in each project. It also includes an automated test suite that will check that everything is working per the permissions, which reduces the time to integrate substantially and can get you up and running with the app in minutes. 

Additionally, this menu has a configurable selection of your preferred ticketing structure for incidents from Nucleus. Select from single tickets per unique vulnerability or a parent/child configuration that maps parent tickets at the unique vuln level to child tickets for each vuln instance.   

These changes will ensure a smoother and more functional integration between Nucleus and ServiceNow, which is much faster to configure and test. We hope the result will be a better experience for our customers’ vulnerability remediation teams and, ultimately, more remediated vulnerabilities.

Performance upgrades to Custom File Schema ingestion 

The custom file upload interface in the Nucleus platform
The custom file upload interface in the Nucleus platform

One of our most popular and most-beloved product features is the ability for customers to upload any data they want onto the platform using our Custom File Schema. The flexibility provided by this capability means that Nucleus customers are never blocked by our lack of a native connector with any of their favorite security tools, even as we continue to add to our roster of integrations with these. Our Custom File Schema is a workhorse that our customers have used for years, and we’ve incorporated many lessons learned in building file ingestion into the product over that time.  

We are pleased to share that we’ve made some low-level changes to this functionality to improve the speed of these file ingestions. Best of all, no changes are required by customers to enjoy the benefits of these enhancements. Stay tuned for additional improvements in the coming months! 

Upcoming Release Spotlight:
Enterprise Scale Asset Group Restrictions

We are greatly enhancing Asset Group Access Control (AGAC) functionality in the coming quarter. Once released, Org Admins can restrict their users’ asset group access in the context of SSO Team Mapping in Nucleus. With this upcoming release, Org Admins can create teams within Nucleus, map an SSO object to that team, and restrict that team’s access to specified asset groups. Currently, only a single user’s access can be restricted, which can be cumbersome for sprawling enterprises with tons and tons of users. We will also give the “Add Team” modal a facelift to better accommodate these changes.

This release will be available in closed beta by the end of the quarter. Please get in touch with Nucleus Support if you want to be added to the beta program or would like to learn more.

  • Fixed an issue where the Crowdstrike last import date was incorrectly showing as “never” in certain cases.  
  • Fixed an issue where the teams filter applied on the active vulnerabilities page was not applied when creating a report.   
  • Fixed an issue where finding descriptions were not rendered correctly, nor consistently between the interface and API when certain HTML tags were included as part of the description. 
  • Fixed an issue where duplicate entries of finding instances in the CSV attached to ServiceNow tickets were included.
