This new analysis feature helps you build a technology profile, showing you what websites are built with, such as CMS, application servers, frameworks, e-commerce platforms, Javascript libraries, and much more, as you can see from the above screenshot.


In a separate tab, to the right of the host list, you'll find a 'Screenshots' option. This new feature allows you to visualize screenshots of all assets in an extensive way, as shown here:

Additionally, it's also possible to see the different screenshots by looking at the Explorer tab’s main dashboard and hovering over the listed open ports highlighted with a white sheet. Once that's done, a screenshot snippet will appear next to the position of your pointer, which will provide you with a home page visual preview.

WAF Detection

WAF Detection helps security researchers during the application discovery and software identification phase and serves well to keep an eye on how many of your assets do or do not have any WAF to protect them.

WAF Detection

Which WAFs can be detected?

ASI can detect almost any kind of WAF—and just to mention some of the more popular ones, they include: Cloudfront, Cloudflare, AWS Elastic Load Balancer, CacheWall, Incapsula, Kona Site Defender, DOSarrest, Zenedge, BIG-IP Local Traffic Manager, NetScaler AppFirewall, Wordfence, and many other commercial and generic WAFs.


With these new features in ASI Explorer, organizations can gain even more visibility over the status of their digital assets in a quick and centralized manner, covering previous asset data from our original 'Explorer' version while adding new and critical information about server technologies and software versions, as well as useful crawling details.

Take advantage of this bold new infosec feature—get a clear picture of all your assets and begin securing your IT infrastructure as quickly as possible, request access to ASI today.
