Tenable.io

I've been using this product since it began as an open source product, I really like it and for the money, I think it's probably the best choice for most companies who need a product like this. Over the years I've seen the interface change quite a bit and sometimes I think it's a bit unclear how to do certain things and the different packages can be confusing, these are the only reasons I'm giving it a 9 instead of a 10.

Tenable.io is a useful tool to use in any scenario where you are looking to increase your visibility of security vulnerabilities in the organization. It supports a large number of use cases for vulnerability management and would only not really be very appropriate for anything that is not supported by the solution (not yet encountered in our organization).

The software is well suited for Information Technology departments that need a way to constantly check their servers and equipment for any and all vulnerabilities. This would be of huge importance to larger organizations with large networks and multiple servers. The software might be less suitable for a smaller organization with a more localized network or need, but that isn't necessarily a guarantee. I think it's appropriate for any Information Technology departments.

I give it this rating since I have never had an issue with receiving adequate support for this product. Any and all concerns have been dealt with in a timely manner, and there are ample options for getting help with any issues a user might experience with working with this product.

Tenable.io works in almost any scenario imaginable. It can scan your cloud environments with pre-configured AWS/Azure scanners. It can give you an external view of your infrastructure, or scan internally. There are also agents you can deploy for assets on a network you don't have access to scan over. I imagine that per asset licensing would be prohibitive for extremely large environments when you could do a Nessus Professional or Security Center deployment instead, but I haven't researched those options much since we're at 800 assets total.

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.)

Excellent for standard vulnerability scanning, especially for AWS and with the web and PCI scanning, it provides a complete package.

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.
