Likelihood to Recommend

Nessus

Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.
Tejas Gandhi | TrustRadius Reviewer

Tenable.io

Tenable.io is a cost effective Internal and External scanner. The Internal scanner came with a .ova, so it was very simple and quick to deploy it into our ESXi environment. It has a cloud-based dashboard for management and the internal scanner is configured to auto-update from Tenable.io. The license came with 4 External PCI scans (with remediation) a year.

Pros

Nessus

  • With Nessus we can find the missing critical patches for a server or workstations.
  • Nessus points out any vulnerable or outdated software Technologies used in the system, thus eliminating any chances for security flaws being turned up.
  • Nessus typically points any configuration level issues in accordance with the OWASP guidelines. Even the configuration of SSL related which are most of the time handled by some vendors or 3rd parties.
  • Nessus not only lists out these Vulnerabilities but describes clearly the vulnerabilities in details with its thousands of plugins updated regularly, the tool also recommends solution with practical details of easy implementation.

Tenable.io

  • Scans using on-site and cloud scanners, giving you visibility from different angles.
  • The best in the business when it comes to plugin accuracy and coverage.

Cons

Nessus

  • Interaction with some other tools like Metasploit.
Omar Israel Sánchez Monroy | TrustRadius Reviewer

Tenable.io

  • There doesn't seem to be a feature to replicate a previous scan with the same IP addresses as before. You have to manually enter them each time.
  • It would be nice to be able to see the DNS (such as hovering to see it) without having to click on the actual IP address under the specific vulnerability.
  • It would be nice to be able to sort the vulnerabilities found in different ways. There are some options available, but more would be a plus.

Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.

It's very much a plug and play application that the user can go into with limited knowledge and set-up scans in minutes.

We have never had to contact them. We only contact Tenable when it comes time to renew Nessus.

Support is usually really great at walking you through any steps you need to take when you get stuck on something. There are a few false positives and errors that have come up over the years that required their help to get through. Unfortunately, the steps required to diagnose some problems are more tedious than I think should be necessary. (IE: SQL instances can throw errors that clog up your logs because one plugin affects it in a certain way. The process to diagnose this is to watch timestamps of plugins in a log while monitoring the SQL logs at the same time and using your best guess as to what is causing it.)

Alternatives Considered

Nessus

Tools like Qualys, Rapid7 stack up well against Nessus, but I think Nessus is superior overall when compared to them, given the features it has.
Tejas Gandhi | TrustRadius Reviewer

Tenable.io

Tenable.io has a comparable set of features, with excellent support and a competitive price. After less than desirable experiences with another company, we moved to Tenable and haven't looked back since.

Return on Investment

Nessus

  • Preventing attacks.
  • Saving the time of deep analysis.
  • Saves money.
Omar Israel Sánchez Monroy | TrustRadius Reviewer

Tenable.io

  • Our customers are requiring monthly internal scans and yearly external scans. Getting both in one was very convenient.
  • The time saved no longer having to manually check servers, switches, and firewall for vulnerabilities. The automated scans have allowed me more time to remediate the issues.
  • Having a third party shows the vulnerabilities and severity, has been helpful with persuading management the necessity of updates and upgrades.
