Note: This post was originally published in March 2024. It has been updated to reflect new capabilities to Tanium Certificate Manager that were announced in April 2025.

Your endpoint environment is constantly changing, introducing new devices to manage and new risks to mitigate. With Tanium Certificate Manager, we’ve expanded Tanium’s core visibility and control to cover more emerging use cases—and to close more of your exposures—from our single, unified platform.

Read on to explore how Certificate Manager can give you comprehensive, real-time visibility into your certificates, their current strengths, and when they will expire.

New for 2025: Certificate Replacement workflow

Tanium’s new Certificate Replacement workflow, part of Certificate Manager, is designed to assist customers in rotating their SSL/TLS certificates quickly and efficiently, especially in emergency situations. This feature was designed for Tanium Cloud and GovCloud users who need to ensure their certificates are replaced before they expire to avoid outages. The workflow provides a step-by-step guide to help users navigate the replacement process seamlessly.

Certificate Inventory

Additionally, the Certificate Inventory page offers a comprehensive certificate-level view of all certificates in a customer’s environment, including those for on-premises, cloud, and GovCloud customers. This page enables users to filter certificates by upcoming expiration dates and initiate necessary actions, such as replacements, directly from the inventory.

Figure 1: The Certificate Inventory tab introduces the ability to launch actions like “Replace” or “Download Certificate,” which can be accessed under the Actions column.

Activity Log

Furthermore, the new Activity Log page allows users to view historical actions taken around certificate replacements, ensuring they can track and review past activities.

What is Tanium Certificate Manager?

Studies show the average enterprise deploys 50,000+ digital certificates, and managing these has become mission-critical.

Unfortunately, many organizations struggle to maintain visibility and control over their certificates. Most attempt to manage their certificates manually via spreadsheets or by using legacy point tools that fail to provide real-time visibility into every one of the organization’s certificates located on every endpoint of their environment.

The result? Many organizations:

• Experience outages and compromises of their web services, creating lost revenue, reputation, and productivity.
• Invest a lot of time and effort attempting to manage their certificates, and still have weak, unknown, and expired certificates in their environment.
• Create risk by deploying exploitable certificates in their network and failing to integrate certificate management with their cybersecurity and IT functions.

Tanium’s Certificate Manager solves these problems. With Certificate Manager, you will:

• Find your certificates. Certificate Manager gives you comprehensive, real-time visibility into every certificate in your environment—including certificates that traditional tools often can’t find. From there, Certificate Manager tells you the health and status of your certificates and sends you alerts when one is about to expire. Then, Certificate Manager presents all of this information in a single inventory that makes certificate management simple.
• See where they are stored. Certificate Manager gives you an accurate, real-time picture of where your certificates are located on your endpoints. With this view, you will improve your security posture by quickly seeing which of your certificates are from authorized Certificate Authorities (CAs) and which are not and by knowing exactly which networks and ports to scan for indicators of compromise.
• Verify and improve their security. Finally, Certificate Manager analyzes the security level of each of your certificates and tells you which are stronger and less vulnerable to being compromised and which need a higher level of encryption. To do so, Certificate Manager shows you the key size of each of your certificates, highlights which need longer and stronger keys. With Certificate Manager, you will see where you are most vulnerable, and your organization can take prioritized action to close your biggest risks.

In sum: With Certificate Manager, you will reduce the time and effort you spend managing your certificates—while improving the accuracy and effectiveness of your processes—leading to fewer service disruptions, security risks, and wasted staff-hours.
