Transfer data packets safely
with PRTG SSL monitoring
- PRTG uses SSL and TLS protocols to check devices
- PRTG monitoring data can be accessed via SSL
- Individual SSL certificates can be imported
PRTG determines the extent to which your connections are protected
Safe data transmission via the Internet or the company network is one of the fundamental aspects of IT security. The instruments used to ensure safe data transmission are the hybrid cryptographic protocols Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL). In order to transfer data safely, IT administrators must know which encryption possibilities are available to devices at any given time.
To avoid sending data via unsecured connections, SSL monitoring checks your devices for their SSL/TLS capabilities. To do so, PRTG has developed the SSL Security Check Sensor, which tests the selected device for its possibilities of being accessed via these security protocols. You can therefore learn if your connections are strong, weak, or not protected at all.
PRTG also lets you use SSL to encrypt your own monitoring data. For even this data may contain sensitive information, information which must be protected against unauthorized access while being sent across the company network. Individual SSL certificates can be imported for this purpose.
With PRTG, everyone will work with peace of mind.

How SSL monitoring with PRTG works
iWhat 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.
Device Port Sensor
The sensor on the device’s port establishes whether it can connect to the protocol (“accepted”) or if the connection is “denied,” and based on this information provides a sensor status:
- SSL 2.0: weak security (“warning” if accepted, "up” if denied)
- SSL 3.0: weak security (“warning” if accepted, "up” if denied)
- TLS 1.0: weak security (“warning” if accepted, "up” if denied)
- TLS 1.1: strong security (“up” if accepted, otherwise “gray”)
- TLS 1.2: perfect security (“up” if accepted, otherwise “gray”)
SSL Security Check Sensor
The SSL Security Check Sensor monitors Secure Sockets Layer (SSL) connectivity on a chosen port on your device.
This sensor attempts to connect to various SSL/TLS protocol versions using the device’s specific TCP/IP port number, and returns a value that corresponds to whether or not the respective protocol is supported.
The security rating displays the connection security of the selected port by way of one of the following statuses:
- Down: No security protocol is available. The sensor is unable to connect to any of the protocols.
- Warning (weak): The sensor is able to connect to at least one of the weak protocols SSL 2.0, SSL 3.0, or TLS 1.0.
- Up (strong): The sensor is only able to connect to one of the strong protocols TLS 1.1 or TLS 1.2. Connections to weak protocols are not possible.
This type of sensor uses lookups to determine the status values of one or more sensor channels. This means that the possible statuses are defined in a lookup file. You can change the behavior of a channel by editing this lookup file. For more details, see: Define lookups.

A sneak peek into SSL monitoring with PRTG
Quickly see which devices support which encryption
– even while on the go
PRTG can be started within minutes and it's compatible with many mobile devices.
Four good reasons
to choose PRTG as your SSL monitoring tool
Ensure secure data traffic
Constant monitoring guarantees that security loopholes due to insufficient SSL/TSL capabilities are eliminated as quickly as possible.
Secure an overview
Our dashboard provides a convenient overview of the status of the encryption that is supported by your devices’ ports.
Stay in the know
If the security rating changes, you’ll be notified at once, wherever you happen to be.
Instead of checking device ports individually, you can simply rely on the PRTG sensors and notifications.
