Nessus has been a core component of information security. We evaluated a lot of different tools before and we always knew that the threat intelligence level behind Nessus was really good. I’ve had a lot of success with it.

Nessus is essential to our security. We’ve had a situation where we realized that one of our devices was unsecured and Nessus successfully identified the threat. Nessus also helped us identify other unsecured devices in our network which dramatically improved our security.

Each day things are becoming more and more digital. This means that we have to actively think about data integrity and confidentiality. Tenable limits the cyber exposure which makes it less likely to have security incidents and data integrity issues.
