This Rapid7® Nexpose® 5.1  release features improvements to security configuation assessment, Web application security, scanning and documentation, and expanded virtualization support.

Release 5.1 is one of many exciting deliveries in 2012 in response to your direct feedback. It incorporates the full commitment of Rapid7 to delivering a great product to you, our customer. The release includes improved asset searches and reporting with our new, extended Dynamic Asset Group criteria. If you are using Advanced Policy Engine for security configuration assessment, we now provide USGCB support as well as a high-level overview of your policy compliance across your organization. 

For those of you looking to migrate to newer platforms we have enhanced the backup-and-restore feature to allow cross-platform migration in addition to a smaller footprint of backup files. In terms of coverage, we rounded out our checks for the OWASP Top 10, released more than 3400 checks since the 5.0 release, and improved accuracy of our SSH vulnerability checks. We trust that you’ll find these enhancements useful. Keep an eye out for continued enhancements throughout 2012, and as always, please keep the feedback coming on how we can make Nexpose even better.
