Tenable Nessus is a world-leader in active vulnerability scanners. It features high-speed discovery, configuration auditing, asset profiling, sensitive data discovery, and vulnerability analysis of your security posture. Nessus scanners may be distributed throughout an entire enterprise, inside DMZs, and across physically separate networks. It is free of charge for personal use in a non-enterprise environment.
|Operating Systems||Linux (32 and 64 bit) FreeBSD Windows (32 and 64bit) MacOS X Solaris (Sparc 64 bit) iPhone (iOS)|
Release Notes: A possible deadlock occurring under certain conditions at the end of the scan has been corrected. The overall memory usage has been reduced by using a different memory allocator (Linux only). A memory leak in webmirror has been corrected. This release fixes an issue occurring when scanning for IPv6 targets on the same local subnet (Linux). It fixes the cross-references in the /plugins/description API. It switches the default plugin database to "low memory usage" (qdb_mem_usage=low) on new installations.
Release Notes: This release improves the packet capture driver on Windows 7 and newer, has the ability to export reports as full DBs which can be moved from one scanner to another, has a new, faster Web mirror plugin, and adds many bugfixes.
Release Notes: This is a major release that provides several new features and enhancements. IPv6 is now supported on all platforms (including Windows). Nessus server support for Windows 8 and Windows 2012. Adds attachments within scan result reports. A Mac OS X preference pane. Digitally signed Nessus RPM packages for supporting distributions. Smaller memory footprint and reduced disk space usage. A faster, more responsive Web interface (uses less bandwidth). No longer need to visit the Tenable website for an activation code.
Release Notes: The major issues addressed in this release include enhanced support for UTF-8 encoding problems in reports and more conservative detection of network congestion errors during scans. A new build for Solaris 10 is available.
Release Notes: This release contains enhancements and minor bugfixes. It also improves stability on all platforms, and solves Windows-specific issues related to installation and packet forgery. From a user perspective, the only change is that it is now possible to specify a separate list of UDP and TCP ports to scan on all targets. This is set in the "Port scanner range" field when you create a new policy or modify an existing one (e.g. if you wanted to scan TCP ports 1-1024 and UDP ports 1-200, the syntax is: "T:1-1024,U:1-200"). A build for FreeBSD version 9 is now available.
