For small businesses that are tech savvy, I was looking forward to using this scanner. However the price hike this year makes it unattainable. However the current price is ridiculous. I loved using the scanner for home testing, guess I'll be switching back to openvas.
Been using Nessus since it was released, even paid for it for many years. Qualys is a ripoff. Tenable has done a good job improving the core functionalities of the product. We've been using the commercial version, which has been a bit slow. But lately the plugins have become unreliable.
Currently looking for something better. Not sure what some of the other reviews are talking about. I just installed the Home Feed, and was able to scan IPs off my local network over the Internet , and had no licensing issues.
Great product. Kicked out some nice reports that I can use. Works alright for scheduled scans; but alternations are clunky and upgrades are painful. We use the enterprise edition.
The world needs an easy to use stand-alone desktop edition again for one-off scans. Apparently Tenable has recently stopped providing trial versions even though their license agreement still states that they do and minimal pre-purchase sales support because it was apparently taking up too much of their time. IOS XR is not supported in case that matters to you. Even more disconcerting, for their plugins that indicate were for IOS XR, I checked the code of two of them and they do not obtain IOS XR version info or contains the affected versions in the matching statement.
Finally, support from the sales organization was less than helpful and let us with a very bad impression. Most high-level network traffic, such as email, web pages, etc reach a server via a high-level protocol that is transmitted reliably by a TCP stream.
To keep different streams from interfering with each other, a computer divides its physical connection to the network into thousands of logical paths, called ports.
So if you want to talk to a web server on a given machine, you would connect to port 80 the standard HTTP port , but if you wanted to connect to an SMTP server on that same machine you would instead connect to port Each computer has thousands of ports, all of which may or may not have services ie: a server for a specific high-level protocol listening on them. Nessus works by testing each port on a computer, determining what service it is running, and then testing this service to make sure there are no vulnerabilities in it that could be used by a hacker to carry out a malicious attack.
Nessus is called a "remote scanner" because it does not need to be installed on a computer for it to test that computer. Instead, you can install it on only one computer and test as many computers as you would like.
Nessus comes in two parts, a server called nessusd and a client, which can by any of several options. The server is the part of Nessus that actually runs the tests, and the client is used to tell the server what tests to run on what computers. Therefore, once the server is set up and running, an administrator can run regularly scheduled Nessus tests using a client written for almost any platform.
Go to www. This will install the Nessus server app and a client on the unix based machine note: this includes Mac OS X and above with developer tools installed. To run a scan, you must have the Nessus server running on some machine, then start up a Nessus client.
The client will look something like this:. The two most important tabs are "Nessusd host", which allows you to enter in the IP address of the Nessus server you will connect to, as well as the username and password needed to connect to this server.
The other critical tab is labeled "Target Selection". This is where you specify which host s you would like to scan. Once you are ready to scan, hit the "Start the scan" button.
