$50 Million Series A Investment in Tenable from Accel Partners

I am extremely pleased to announce that Tenable has received its first institutional round of funding: a $50 million investment from Accel Partners. The investment will help us continue to develop and improve our solutions and improve our customers’s experience.

Tenable celebrates its 10th anniversary this month. During that time, we’ve made Nessus the number one trusted vulnerability scanner in the world with more than 1 million users across 150 countries. We did this though a combination working closely with our community and continually adding improvements to make our users’s lives easier and through our own innovation to push Nessus to do even more than vulnerability assessments. Today, Nessus not only detects vulnerabilities, it finds malware, botnets, credit cards, configurations that will get you hacked or fined and most recently, issues with your iPhone and Android devices.

Tenable’s SecurityCenter, our enterprise platform for Nessus, has also become the preferred enterprise security solution for nearly 1,000 enterprise customers including the entire U.S. Department of Defense. We have changed the vulnerability management paradigm through our unique combination of scalable network vulnerability monitoring, vulnerability scanning and log management. It has helped our customers break down traditional security silos, have a unified view of their security posture and respond quicker to incidents and audits than was previously thought possible. 

As we prepare for the next 10 years, we’re particularly focused on Tenable’s growth in support of our customers. Growth is in two areas – great technology and great people. During the past year, we’ve doubled our amazing staff and plan to double it again in the next two. Tenable employees tirelessly support, train, research and develop solutions for all the world’s leading industries including financial service, government, university, retail, energy, technology, healthcare, media, telecom, internet and consulting organizations. Tenable’s technologies will also continue to keep pace with the ability to measure risk and monitor security for new attack vectors from mobile devices, cloud applications and virtual networks. We’re constantly researching new forms and techniques of vulnerability analysis, risk reporting and attacker methods which we can turn into actionable data for our customers.

And lastly, on behalf of Tenable’s employees and my co-founders, Jack Huffard and Renaud Deraison, I’d like to thank our user community. Without your interest in Tenable’s solutions, we would not have been able to invest so much into the research, development and staffing required to offer the breadth and depth of security solutions we do today.

Many people say that computer security is a huge problem and it’s not getting better. We’re much more optimistic. We named our company “Tenable Network Security” because we believe network security is something that can not only be obtained, but sustained. We’re committed to helping you enhance your network security to a “Tenable” position, and with our new partners from Accel and 10 years of monitoring security for some of the world’s largest and most complex networks, we’re confident we can continue to help you protect your networks today and well into the future.
