Engineering, human resources, product management and billing: Here's how four employees with a wide range of skills are making their mark in cybersecurity.

At Tenable, we're united in a common mission: to help organizations around the world reduce their cyber risk. While the mission requires a formidable engineering bench, you don't need to be a techie to make a difference in cybersecurity. 

Don't let misconceptions stand in your way – get the facts on five common myths about vulnerability assessment.

The simple truth of vulnerability assessment is that it's not always an easy task to accomplish, especially if you're new to it. Complications arise, and if you sometimes find yourself confused by one part of the process or another as a result, that's nothing to be ashamed of. 

The Nessus team continues to develop advanced assessment capabilities, including visibility into new operating systems, exploitable vulnerabilities and container instances.

When Renaud Deraison first announced Nessus on Bugtraq on Apr. 4, 1998, it was an “alpha” release. Today, as Nessus nears its 23rd birthday, the alpha release has become the alpha vulnerability scanner, the most widely adopted vulnerability assessment tool in the world.

More than 1,500 teams from nearly 140 countries competed in Tenable's first-ever Capture the Flag competition. And the winners are...

That’s a wrap on the first Tenable Capture the Flag event! 

We’d like to say a huge thank you to everyone who participated. We were overwhelmed by the response from the community. A few stats:

Building a precise inventory of existing assets across your attack surface is essential for effective vulnerability management. Here's how the asset detection process in Nessus scanners can help.

Establishing the right configurations and settings can improve Nessus scan results when scanning through firewalls.

Of all the factors that can inhibit a successful Nessus scan — busy systems, congested networks, legacy systems, hosts with large amounts of listening services — firewalls (and other types of filtering devices) are one of the major causes of slow or inaccurate scans. Network-based firewalls are essential for an organization’s perimeter protection and internal network segregation, while host-based firewalls are common on both Linux and Windows systems. 

Turning your Nessus scan results into actionable reports helps you dynamically visualize the vulnerability assessment process.

Conduct compliance audit scans effectively and efficiently with Nessus Professional by leveraging these best practices. 

Tasks required to maintain compliance don't find themselves on most people's lists of favorite activities. But while such regulatory responsibilities can sometimes be taxing, complex or tedious, that doesn't make them any less necessary. Among the standards and practices pertaining to information security, compliance scanning is one of the most important.

Penetration tests and vulnerability assessments make for an excellent tandem approach to cybersecurity. 

While similar — and sometimes confused for each other — penetration tests and vulnerability assessments are decidedly not the same thing. There are important, fundamental differences that actually allow these two tactics to be used in tandem.
