Dear Nessus Community,
On behalf of Tenable Network Security, we would like to thank you for making Tenable's Nessus vulnerability scanner the most widely used scanner in the world. Over the last five years, we have seen Nessus grow globally to over 5 million downloads and we have been there every step of the way. The core Nessus engine is powered by our world-class vulnerability research content which includes over 20,000 plugins, enhanced features such as IPv6 scanning, free mailing lists, online search tools and free clients.

Nessus has become not only a popular tool for conducting security audits but we have extended its capabilities to conduct agent-less patch audits and configuration audits, as well as locating sensitive data.

Looking forward, we plan to further increase functionality, such as SMBv2 support to better audit Windows 2008 and Windows Vista, and further expand our abilities to conduct even more comprehensive vulnerability and configuration audits.

In the process, the Nessus scanning engine has been provided to our rapidly growing community as a free download with research content licensed through two plugin subscriptions. Our Nessus users know these as
the 'Registered Feed' and the 'Direct Feed' subscriptions. These subscriptions have been available for over three years and have been utilized by countless individuals, consultants, companies, governments and other organizations.


We continually interact with the Nessus community and review our capabilities to ensure Nessus continues to meet and exceed the needs of its users. Since creating and releasing the subscriptions, two distinct user groups emerged. They are the home user and the commercial user. To better reflect the needs our community, we have decided to update our Subscription licensing policy and are announcing the planned
change (as outlined below and accompanied by a FAQ) that will go into effect on July 31st, 2008.

' First, we will continue to enable all users to download Nessus for free.

' Second, due to computers and personal networks having become ubiquitous in homes around the world, Tenable will launch a 'HomeFeed' with all Nessus vulnerability plugin updates for home users at no charge and with no delay. We are excited to offer the latest vulnerability checks for personal, non-commercial use and strongly encourage home users to audit their computers and networks for the newest security flaws.

' Finally, Tenable's 'Direct Feed' will be re-named to the 'ProfessionalFeed' and the 'Registered Feed' will be discontinued. The ProfessionalFeed will entitle subscribers to the latest vulnerability and patch audits, configuration and content audits and commercial support for their Nessus 3
installation. The ProfessionalFeed will serve as Tenable’s commercial subscription and will be
required for individuals and organizations that want to use Tenable's Nessus plugins commercially.

The decision to alter the licensing policy is the result of significant deliberation and will benefit both home users and commercial users. The change will ensure our ability to invest in the future roadmap for Nessus and to expand our research, support and training capabilities to serve our growing community. We realize
this may affect some individuals, corporations and organizations that use the currently available 'Registered Feed' in production audits and commercial services. Because of this, Tenable is offering a 25 percent rebate for the Direct Feed subscription service (normally available at $1200 per year), beginning May 14, 2008 until July 31, 2008 only when purchased through Tenable's e-commerce site.

Additionally, we understand that there are those in the Nessus community that serve broad social and educational objectives and we want to make certain that qualified charitable and information security teaching/training organizations have access to the ProfessionalFeed free of charge. To this end, Tenable will provide ProfessionalFeed subscriptions to charity and teaching/training organizations at no cost for those that qualify.
As always, Tenable will continue to perform the in-depth research, testing and development to keep Nessus the leading vulnerability and network auditing tool available to both home and professional users.


Regards,
- Ron Gula, Chief Executive Officer
- Renaud Deraison, Nessus creator and Chief Research Officer
