Did you try Undet Browser with Undet? You can browse structured e57 files in it. Undet Browser will help you manipulate point cloud slices using 360 scan images. And also, you can draw points in SketchUp. Undet Browser webinarr - Undet Browser for SketchUp webinar - YouTube
I once thought of integrating the recognition of planes, corners, and lines in Undet Browser to transfer them to SketchUp. But it turned out that it is not productive, especially when the object is more complex. When the object is simple, it can quickly be done in 3D space using point clouds.
It is exactly what we wanted to achieve with Undet Browser development. For example, In Undet for SketchUp, there is a view sync feature; you can use this function to click on any point cloud points that are not clear to you, and you will see how these objects look in Undet Browser (360degress images). Or you can shift (transfer) the clipping box by clicking on an object in 360 degrees image and find any object/spot in the 3D point cloud.
I can say that this spring, there will be a new version of Undet with many new features, and one of them will be direct real-time image synchronization between the Undet Browser and SketchUp window; you will be able to simultaneously see how the same object looks like in 360 photos and the 3D point cloud.

Vulnerability management is the process of identifying, evaluating, treating, and reporting on security vulnerabilities in systems and the software that runs on them. This, implemented alongside with other security tactics, is vital for organizations to prioritize possible threats and minimizing their "attack surface."
Security vulnerabilities, in turn, refer to technological weaknesses that allow attackers to compromise a product and the information it holds. This process needs to be performed continuously in order to keep up with new systems being added to networks, changes that are made to systems, and the discovery of new vulnerabilities over time.
Once vulnerabilities are identified, the risk they pose needs to be evaluated in different contexts so decisions can be made about how to best treat them. For example, vulnerability validation can be an effective way to contextualize the real severity of a vulnerability.
Generally, a Vulnerability Assessment is a portion of the complete Vulnerability Management program. Organizations will likely run multiple Vulnerability Assessments to get more information on their Vulnerability Management action plan.
Vulnerability scanners are able to identify a variety of systems running on a network, such as laptops and desktops, virtual and physical servers, databases, firewalls, switches, printers, etc. Identified systems are probed for different attributes: operating system, open ports, installed software, user accounts, file system structure, system configurations, and more.
This information is then used to associate known vulnerabilities to scanned systems. In order to perform this association, vulnerability scanners will use a vulnerability and exploit database that contains a list of publicly known vulnerabilities.
If some systems on a network become unstable or behave erratically when scanned, they might need to be excluded from vulnerability scans, or the scans may need to be fine-tuned to be less disruptive. Adaptive scanning is a new approach to further automating and streamlining vulnerability scans based on changes in a network.
For example, when a new system connects to a network for the first time, a vulnerability scanner will scan just that system as soon as possible instead of waiting for a weekly or monthly scan to start scanning that entire network.
Once a vulnerability has been validated and deemed a risk, the next step is prioritizing how to treat that vulnerability with original stakeholders to the business or network. There are different ways to treat vulnerabilities, including:
Performing regular and continuous vulnerability assessments enables organizations to understand the speed and efficiency of their vulnerability management program over time. Vulnerability management tools typically have different options for exporting and visualizing vulnerability scan data with a variety of customizable reports and dashboards.
Threats and attackers are constantly changing, just as organizations are constantly adding new mobile devices, cloud services, networks, and applications to their environments. With every change comes the risk that a new hole has been opened in your network, allowing attackers to slip in and walk out with your crown jewels.
Web application scans submit forms with the test data that depend on the privileges of the credentials that are used in the authentication record. This can have undesired effects and can potentially impact the data.
Keep in mind when these configurations are used instead of test data (credentials with read-only permissions), testing of certain areas of the web application is not included and any vulnerabilities that exist in these areas may not be detected.
Web Crawling and Link Discovery. We request links and forms, parse HTML for parameter analysis and form values, and interact with the web application. We also extract JavaScript based links and can find custom links. Learn more
The first time you scan a web application, we recommend you launch a discovery scan. A discovery scan performs information gathered checks only. This is a good way to understand where the scan will go and whether there are URIs to be added to the exclude list for vulnerability scans. For a discovery scan:
Go to Detections > Detection List to see the vulnerabilities detected by scans on your web applications. This gives you an easy way to review the vulnerabilities detected on web applications in your account without running reports. Use the search and filtering options (on the left) to take actions on one or more detections.
WAS supports basic security testing of SOAP based web services that have a Web Service Description Language (WSDL) file within the scope of the scan. If WAS identifies a WSDL file that describes web services that are within the scope of the scan, WAS will attempt to perform XSS and SQL injection testing of the web services. Check out this article to learn more.
You can opt in to receive an email notification each time a scan in your account is completed. Just turn on the Scan Complete Notification in your account settings. Go to the VM application, select User Profile below your user name (in the top right corner). In the user wizard, go to the Notification Options, select "Scan Complete Notification" and be sure to save your account. Once you've turned on the Scan Complete Notification you will receive an email notification each time a WAS scan in your account is finished. In case of multi-scan, you could configure the frequency of notification email to be sent on completion of multi-scan. You could choose to send email after every scan is completed in multi-scan or completion of all scans in a multi-scan. Learn more
Yes, you can do this by configuring exclusion lists in your web application settings. Exclusion lists are exclude lists and allow lists that tell us which links in a web application to scan and which to ignore. You can define either one or both kinds of lists for a web application. Learn more
If a web application has both an exclude list and an allow list, we treat the allow list entries as exceptions to the exclude list. We will not crawl any exclude list entry unless it matches an allow list entry. We'll crawl all other links including those that match allow list entries.
If a web application has an exclude list only (no allow list), we'll skip all links that match exclude list entries. If the web application has an allow list only (no exclude list), we'll crawl only those links that match allow list entries.
The crawl scope options you choose in your web application scan settings determine where the scan will go. You can limit crawling to the URL hostname, content at or below a URL subdirectory, the URL hostname and a specified sub-domain, or the URL hostname and specified domains. Learn more
Yes. To scan a REST API, enter the URL of the Swagger file in the target definition field on the Asset Details panel. Swagger version 2 and OpenAPI version 3 (JSON format) are currently supported. Alternatively, you can provide a Postman Collection to scan your REST API, which is done on the Application Details panel.
