PRODUCT OVERVIEW

Are your SSL certificates still valid? PRTG will tell you!

It has certainly happened to every sysadmin at some point in their professional life. The website's SSL (secure sockets layer) certificate has expired and you've realized it too late. As soon as the certificate authority or one of the endpoints is unavailable, or the SSL certificate encounters problems, it is time for a website monitoring tool  that keeps a central overview of the SSL certificates. This is where Paessler PRTG comes into play!

Monitoring

Get automated monitoring

PRTG continuously monitors SSL certificates expiration dates, validity, and potential issues. You no longer need to manually check your certificates.

Instead, you can focus on other critical tasks without worrying about missed expiry dates or unnoticed problems that could lead to security vulnerabilities or outages.

Alerts

Receive real-time alerts

PRTG sends immediate notifications via email, SMS, or push messages when SSL certificates are about to expire or encounter problems.

With this proactive approach, you don't have to explain a website downtime caused by a SSL certificate issue to your manager.

Reports

Generate precise reports

PRTG is a network monitoring tool that generates comprehensive reports on SSL certificate status and history, which give you the needed insights to keep track of all your SSL certificates.

You can store the reports in your documentation and are thus also prepared for future network audits.

  • If the common name or subject-alternative names match the host address or SNI
  • Days to expiration
  • Public key length
  • If the certificate has been revoked and if it is trusted as root authority
  • If a self-signed certificate is used

PRODUCT OVERVIEW

”PRTG helps us monitor critical security systems to give customers the peace of mind that their devices are operational and protecting their valuable assets.”

Rob Jackson, President
Integrated Precision Systems

“Monitoring with PRTG is crucial for security. Today’s threats can move low and slow, so in addition to looking at the usual suspects, you also need to keep tabs on other indicators. For example, if a server is running a peak capacity for no apparent reason, you want to know so you can take a look and see what’s up – for example an open connection that is being used to extract data in a ransomware attack.”

Jon Larsen, CIO
Richweb

“When it comes to security, we do of course use classic tools such as firewalls, virus scanners, and intrusion detection systems. However, these are no longer enough today. PRTG provides for additional security by detecting unusual behavior which may be a sign that a hacker has outsmarted our security systems.”

Damir Karacic, IT Administrator

SSL Certificate Monitoring: FAQ

 

What is an SSL certificate and why do I need it?

An SSL (secure sockets layer) certificate is a digital cert that is needed for website authentication and enables an encrypted connection. It's essential for securing data transmitted between a user's browser and the web server. The SSL certificate protects sensitive information like login credentials and payment details from eavesdropping and tampering. SSL certificates also help build trust with users by confirming the website's legitimacy.

Why should I monitor SSL certificates?

Monitoring SSL certificates helps to avoid unexpected expirations of the certificate, which can lead to security vulnerabilities, loss of user trust, and downtime. Continuous monitoring prevent SSL expiry and ensures that certificates are valid and properly configured.

What are the key aspects of SSL certificate monitoring?

Key aspects of SSL certificate monitoring include the certificate's validity period, confirmation that it has not expired, detection of certificate errors and confirmation of the strength of the encryption used. Real-time alerts for issues and detailed reporting are also helpful.

How can I check the expiration date of an SSL certificate with PRTG?

To check the expiration date of an SSL certificate with PRTG, use the SSL Certificate sensor. This sensor continuously monitors the certificate's validity and provides detailed information, including the expiration date. PRTG will send you alerts if the certificate is close to expiring, allowing you to renew it in time.

What SSL metrics can I monitor with PRTG?

With SSL certificate monitoring tools like PRTG, you can monitor several SSL metrics, including certificate expiration dates, validity status, issuer and subject details, and encryption strength. You can also track the performance of HTTPS connections.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
