We offer over 250 sensors out of the box and many customizable options like preconfigured custom sensors and using your own scripts. Phew, there is a lot to monitor, right? Get an overview of all PRTG features here.
With a PRTG Hosted Monitor, you can instantly start to monitor all servers, services, or devices that are publicly available via the internet. If you'd like to monitor targets in your LAN that aren't available over the internet, you can install a remote probe in your network. The remote probe collects the monitoring data from your internal network and connects back to your PRTG Hosted Monitor instance in the cloud, where all monitoring data is available in one place. The remote probe monitors all devices from your network using the sensors you have configured. You can connect as many remote probes as you'd like to make multiple LANs available that may be separated by firewalls, or to use packet sniffing on computers in your LAN. For more details on remote probes and an easy installation guide, please refer to the PRTG Manual.
PRTG Hosted Monitor is offered as a service by Paessler and runs in the cloud. You don't need a PRTG core server installation inside your network because we take over the hosting for you.
With PRTG Network Monitor, you integrate the PRTG core server directly into your network. Please see the following table for the most important differences:

By default, the PRTG Hosted Monitor user interface is only accessible via a secured HTTPS connection. On an operating system level, Amazon's AWS firewalls will ensure the security of your network and, of course, all passwords are secured using individual encryption.
The remote probe continues its monitoring and stores the results. Once the internet connection is re-established, cached data is sent to PRTG Hosted Monitor and written to the database. For details, see the PRTG manual on remote probes. Of course, without an internet connection, you will not be able to reach the web interface of your PRTG Hosted Monitor.
Your PRTG Hosted Monitor will instantly alert you as configured. Available notification methods are push notifications or email, for example. In order to receive these notifications, please make sure your receiving device is connected to the internet.
You can connect remote probes from different locations to your PRTG Hosted Monitor instance: the limit is your total number of sensors.
There's no need for redundant monitoring with PRTG Hosted Monitor. We have built our service so that it frequently saves backups of the configuration file. Should a instance crash, we simply restart your instance for you and automatically roll out the latest backup. The latest backup will not be older than one hour.
PRTG Hosted Monitor uses SendGrid for sending email notifications. These settings are preconfigured and cannot be changed to some other SMTP server. Emails sent by PRTG Hosted Monitor can originate from the following IPs:
By default, the email address of the subscription's owner is set as the sender of the notifications. This can be changed in "Setup | System Administration | Notification Delivery". Please note that depending on your email server's settings on the receiving end, those notifications could be blocked due to the fact that they do not really originate from your domain. In this case, you have two options:
- Update SPF/DMARC configuration on your end, so that it accepts those emails from the aforementioned IPs, see also https://sendgrid.com/docs/glossary/spf/
- Change the Sender Email to something generic like [email protected]
We monitor the email reputation of each instance and take measures to prevent emails being sent from instances with a poor reputation, which usually indicates that the instance is being abused for sending SPAM.
No, neither the license nor the data can be migrated. The reason behind this is that your instance's data is stored in the cloud and you can't simply access it on an operating system level as you could with PRTG on premises. Also, both PRTG Hosted Monitor and PRTG Network Monitor have two fundamentally different pricing structures. The former is a subscription model and the latter a one-time purchase plus maintenance.
On the PRTG Hosted Monitor status page, you can get updates on how our services and features are doing. If there are any interruptions to our service, we will post a note to keep you informed.
Currently, you can only purchase PRTG Hosted Monitor on a monthly basis.
Main advantage is the flexibility you get. Simply change subscription plans whenever you need more or less sensors.
We accept credit card payments.
Flexibility is key.
This is why PRTG Hosted Monitor is pre-billed monthly based on the subscription plan that you choose. If you subscribe to a plan, your credit card is charged up front with the monthly costs and you can use PRTG Hosted Monitor for one month. You can switch plans at any time. The balance on your account will be credited towards the new price. For example, if you select a new plan that costs half as much as the one you originally chose, you can use PRTG Hosted Monitor for a second month without being billed. If you switch plans during a month, you will be billed in part.
In comparison to a perpetual license, a PRTG Hosted Monitor subscription will always give you access to the latest updates, which include new features, numerous improvements, and bug fixes.
The move involves approximately a 15-minute downtime for your instance.
As PRTG Hosted Monitor is hosted in the cloud, you can simply access it via your web browser on any device and you don't need any additional hardware or software.
To gather monitoring data from inside your network, you need to install a remote probe in your environment. This requires a simple PC or server that runs Windows 7 or later in your network.
For detailed hardware requirements for remote probes, please refer to the PRTG manual.
2. What changes do I need to make to my on-premises infrastructure for PRTG Hosted Monitor to work (for example, firewall settings, new Active Directory admin account)?
The actual monitoring of your network will be performed by the remote probe that you need to install in your network. This probe initiates the connection from your local network to the cloud, so you might not need to configure anything (depending on existing network configurations). In general, a remote probe must be allowed to initiate an outgoing connection on port 23560 to your PRTG Hosted Monitor instance.
For details, please see the PRTG manual on remote probes.
We offer up to 10,000 sensors on PRTG Hosted Monitor instances.
If you need more than one instance, you can create an additional one at any time.
