Automating Certificate Discovery, Compliance, and Reporting in Splunk with AppViewX

Managing certificates in Splunk can be a challenge when done manually tracking expirations, parsing JSON data, and running compliance checks all eat up valuable time. To address this challenge, AppViewX now offers a solution that automates the entire process: discovering certificate data from Splunk, parsing JSON data, running compliance checks, and generating reports delivering efficiency and accuracy at scale.

Solving Certificate Management Challenges with AppViewX AVX ONE CLM

Certificates play a vital role in enabling encryption, securing access to applications and devices, and maintaining digital trust. But when certificate lifecycles are managed manually, even small oversights like a missed renewal or a certificate not being pushed to the correct profile can lead to serious technical, security, and compliance issues.

Managing expirations, renewals, and revocations can be especially overwhelming for PKI administrators working across hybrid and multi-cloud environments. Without the right processes in place, expired or misconfigured certificates can trigger outages, expose critical vulnerabilities, and disrupt essential business operations.

That’s where AppViewX AVX ONE CLM makes the difference. It automates certificate discovery across your entire infrastructure, building a comprehensive inventory that gives PKI teams complete visibility to monitor expirations and identify vulnerabilities. Beyond visibility, it automates lifecycle management and policy enforcement, helping PKI teams efficiently handle renewals, provisioning, and revocations.

AVX ONE CLM also acts as a master orchestration solution. It not only automates routine certificate tasks but also coordinates workflows across multiple systems, ensuring accuracy, consistency, and compliance at every stage. The outcome is reduced operational complexity, zero outages, minimized risk, easier audits, and certificate processes that run at peak efficiency.

Now, let’s dive into how AVX ONE CLM integrates with Splunk to deliver visibility, compliance, and reporting.

Centralizing Enterprise Endpoint Certificate Visibility with Tanium and Splunk

Digital certificates are essential for authentication, encryption, and digital signatures. On enterprise-issued laptops, they verify user identities, secure communications, and establish trusted machine-to-machine connections. But managing visibility into these certificates at scale requires more than manual oversight.

This is where Tanium comes in. Tanium is an endpoint security and systems management platform that provides real-time visibility and control over enterprise endpoints, such as laptops. By deploying lightweight Tanium agents on each device, organizations can continuously collect data about endpoint configurations, activities, and security-related events including information about installed digital certificates.

However, collecting the data is just the first step. To truly leverage it, organizations need a way to centralize and analyze this data across all endpoints. That’s where Splunk helps. Splunk is a powerful data platform designed for searching, monitoring, and analyzing machine-generated data in near real time. With its ability to process inputs in formats like CSV, JSON, and more, it’s ideal for turning raw endpoint data into actionable insights.

By integrating Tanium with Splunk, certificate data collected from laptops can be sent directly to the Splunk server for centralized storage and analysis. This integration provides enterprises with a consolidated view of certificate usage and status across endpoints, enabling better visibility, stronger compliance, and more proactive security management.

AppViewX Integration with Splunk

While Splunk collects and stores certificate-related data, the real value comes from turning that raw data into actionable insights. This is where AppViewX helps. By integrating with Splunk, AppViewX automates certificate discovery, compliance validation, and reporting eliminating manual effort and reducing risk. The integration ensures that certificate data from Splunk is not only collected but also organized, analyzed, and used to streamline certificate lifecycle management (CLM) at scale.

1. Connection Establishment

The connection between AppViewX and the Splunk server is established by executing a Splunk archival query.

2. Data Collection

Once the connection is established, endpoint discovery is performed in Splunk. The data collection process follows these steps:

Step 1: Run a stats query

A search with the “stats count” option is executed to get the total number of matching events.

(Ex: source=”e-protector.appviewx.plus.json” -d stats count). This tells us how many results need to be imported into the CLM collection.

Step 2: Run the actual search

A search without the stats option is then executed to fetch the actual results.

The completion time depends on the number of matching events.
The workflow waits until the search finishes or the time exceeds a set limit.
Once complete, a GET API call retrieves the results. The workflow waits until all results are obtained or the time limit is reached.
The fetched data is then stored in a JSON file for further processing.

Step 3: Handling timeouts

The process has a timeout defined in a helper script. If the workflow exceeds this limit, Splunk data will not be captured for that cycle.
In the next scheduled run, the Splunk query is adjusted with the “earliest” option to include missed data from the previous cycle. (Ex: source=”e-protector.appviewx.plus.json” -d earliest_time=-24h@h)
The maximum number of previous-cycle data points to be included can be defined.

We can define the maximum number of previous cycle data points that have to be included in the search.

3. Data Storage

Once the data is obtained, the workflow will proceed to add it to the CLM collection. To ensure uniqueness, A unique identifier is generated by combining the username and subject CN. Ex: 1305733|abcde.uk.dev.net.
For each entry, if the identifier already exists, the record is overwritten; if not, a new document is created.

Along with adding data to the collection, the following details are captured: .

Expiry status (Valid/Expired) – configured in a helper script.
Compliance status (Yes/No) – certificate data is validated against a predefined set of values to determine compliance.
A count of received, added, and overwritten certificates – included in the final notification.

Conclusion:

Manual certificate management in Splunk whether it’s tracking expirations, parsing JSON, or running compliance checks can be slow, error-prone, and resource-intensive. With AppViewX AVX ONE CLM, these tasks are fully automated. The solution seamlessly discovers certificate data from Splunk, parses and processes it, enforces compliance, and generates reports with accuracy and speed.

By integrating Certificate Lifecycle Management (CLM) with Splunk, you can gain a streamlined, reliable, and scalable way to manage certificates eliminating manual effort, reducing risk, and ensuring stronger security and compliance.
