About Us:

N5 Networks (formerly TNL Systems) began in 1991 in Dayton, OH relocating to Eugene, OR in 2001.

TNL Systems began in 1991 developing software solutions for existing telecommunication packages (BBS Systems). A few years after the company started, the internet and the World Wide Web began gaining acceptance and popularity. As the World Wide Web progressed into what it is today the need for more complex solutions and managed services came into high demand. With an obvious strength in these areas TNL Systems became N5 Networks.

Frequently Asked Questions

Why free security audits?


The internet is a dangerous place. Free security audits are provided in order to aid server administrators and website owners the tools they need to identify potential security vulnerabilities and detect outdated software to make the internet a safer place to operate a business and to use in general.

My scan didn't find anything am I safe?


The security audit is intended as tool to help identify possible issues. It is not an all-inclusive test of your website security. Security vulnerabilities can come in all shapes and sizes and no one tool is qualified to test and discover all of them. Tools like the security audit help make the job of identifying potential problems easier.

Why does it take so long to scan my site?


We have a team of monkeys who are manually surfing your site, this takes time. Just kidding! To protect our network integrity, we have set limits on the number of simultaneous scans our system will perform at any given time. Depending on the size of your site and the number of sites ahead of yours the scan may take some time. Scan results are delivered within 24 hours of submitting them 90% of the time you will get your results within an hour or two.

How can I identify your scanner in my logs?

For web servers look for the user agent called:
Mozilla/4.75 ( (Evasions:XXXXX) (Test:XXXXX)

What exactly does your scan cover?

Our site scanner uses the GPL Nikto scanning engine. Here is some more information directly from the Nikto home page:

Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6100 potentially dangerous files/CGIs, checks for outdated versions of over 950 servers, and version specific problems on over 260 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software. Scan items and plugins are frequently updated and can be automatically updated.

Nikto is not designed as an overly stealthy tool. It will test a web server in the quickest time possible, and is fairly obvious in log files. However, there is support for LibWhisker's anti-IDS methods in case you want to give it a try (or test your IDS system).

Not every check is a security problem, though most are. There are some items that are "info only" type checks that look for things that may not have a security flaw, but the webmaster or security engineer may not know are present on the server. These items are usually marked appropriately in the information printed. There are also some checks for unknown items which have been seen scanned for in log files.

Nikto is written by Chris Sullo and David Lodge..

Our scan employs some additional options provided by Nikto such as the anti-IDS options, deep CGI inspection and a handful of the mutate options.

Someone is Scanning My Site!
