Individual network audits and permanent monitoring
Network audit tools
IT managers perform a network scan or network audit to get an overview or solve a specific problem. There are many tools on the market designed especially for network audits. The fundamental problem, however, lies elsewhere: many networks are not monitored on a permanent basis This leads to disruptions, critical errors, and for sysadmins, the unshakable feeling they have lost all control of their networks.
PRTG monitors your network around the clock. It monitors your hardware, applications, bandwidth, traffic, and much more. With PRTG, you’ll be promptly notified in the event that a server, switch, or router is causing a problem. You can therefore quickly take action to make sure your network stays in tip-top condition. PRTG helps you keep disruptions and crashes to a minimum. You get a constant overview of your entire network. Upon installing the software, all devices within a specified IP range are scanned and added automatically.
5 sensors for checking the status of your network
What is a sensor?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Three situations calling for a network audit
New on the job
To get started, newly hired IT managers need an overview of the company network. Unfortunately, such an overview is not always available. And while it’s important to read the various company manuals, it’s likely new employees will not find the time to do so. Checklists, furthermore, are usually missing from the initial training process. PRTG provides for the necessary overview.
Here’s another reason why admins wish to perform a network audit: they have a specific problem but aren't exactly sure where it lies. Network connections are down, devices are acting up, or the company is dealing with minor or major malfunctions. PRTG helps you get to the root of the problem.
A growing network
As companies grow, so do their IT infrastructures. This means more and more devices and applications. Things get even more complicated when a company expands to new locations. Another problem involves shadow IT such as USB sticks which are simply inserted into devices and thus present a security concern. PRTG also helps you get a handle on larger networks.
Your network on a glance – even on the go
PRTG can be started within minutes and it's compatible with many mobile devices.

Network audits: 3 core elements for checking the status of your network
Hardware is the basis for every network audit. As a sysadmin, you need an overview of the devices in your network. This includes the total number of network devices and confirmation that all security-related updates have been performed.

What kind of traffic runs through your network? Which IP addresses and applications generate the most load? PRTG shows you exactly what is going on in your network.
PRTG sensor tip:
Practical tip: “Hey Sascha, when it comes to network audits, what are your three golden rules?”
“First of all, take your time. It’s important that managers grant their sysadmins plenty of time to prepare the network audit. Second, and conversely to the first rule, once the audit is run, time is of the essence. You’ll want to make sure any loopholes revealed by the audit are closed as quickly as possible. Finally, rerun the audit often. Regular network audits are an important part of a continual improvement process.”
Sascha Neumeier, Paessler AG IT Department
Network security audits: The benefits and limitations of PRTG
Improve overall security in the network
PRTG helps you make your network more secure. Among other things, it monitors firewalls, servers, and ports. You’ll notice unusual traffic and receive an alert if security updates have not been performed. If a critical error arises, PRTG lets you exclude a number of possible causes.
Security software and audits
PRTG is not security software. It is therefore unable to actively protect your network from attacks. To stop attacks, you'll need additional security software. What’s more, a security or IT security audit has its own standards, guidelines, and procedures.

Check your network for free
It doesn't cost a thing to try PRTG. All the software’s sensors and features are free for the first 30 days. You can use PRTG to check your network. If you need more detail, go ahead and pick up a separate network audit tool. After the free one-month trial, you can continue to access 100 sensors that never expire, as well as the alarm, reports function, and other features which will allow you to benefit from permanent network monitoring.
One centralized tool
Tired of a mishmash of network audit and network monitoring tools? Maybe it’s time to switch to PRTG. PRTG is a centralized tool for monitoring your entire network. It is compatible with all the biggest manufacturers, including HP, Cisco, and Dell. You can also use PRTG for distributed networks.
Improve the performance of your network
PRTG lets you quickly identify loopholes. Network monitoring is essential for improving the performance parameters of your network. When the network runs more smoothly, your coworkers are happier and the support desk receives far fewer complaints. As availability improves, so does uptime.
Keep an eye on everything: At all times and from anywhere
PRTG keeps a constant eye on your network devices, applications, and traffic. The software is available for desktops, tablets, and even smartphone apps while on the go. And thanks to PRTG alerts, you won't have to waste a single second wondering if everything is OK. PRTG is like a pair of eyes that never loses sight of your network.
PRTG monitors your IT infrastructure over long stretches of time. You can therefore run analyses to identify any changes that may not be obvious in the short term. These reports are easy to understand for both department heads and those with little technical expertise.

Network audit tools:
A large selection, but choosing the right one is a must
Many tools on the market
There are many different tools for performing a network inventory or audit. These include Network Inventory Advisor, Spiceworks, Total Network Inventory, Lansweeper, Open-Audit, and Emco Network Inventory.
Quick command line check
For specific problems, many sysadmins run a quick command line check first, e.g. via a ping query, traceroute, or netstat. But in reality, this is like trying to find a needle in a haystack.
Centralized monitoring tool
If you’re looking for a quick check, PRTG may not be the tool for you. PRTG is a permanent monitoring solution for your entire network. It constantly keeps you up-to-date such that future network audits become obsolete.
