Our Review Methodology

How We Test & Score Tools

We’ve spent years building, refining, and improving our software testing and scoring system. The rubric is designed to capture the nuances of software selection and what makes a tool effective, focusing on critical aspects of the decision-making process.

Below, you can see exactly how our testing and scoring works across seven criteria. It allows us to provide an unbiased evaluation of the software based on core functionality, standout features, ease of use, onboarding, customer support, integrations, customer reviews, and value for money.

Core Functionality (25% of final scoring)

The starting point of our evaluation is always the core functionality of the tool. Does it have the basic features and functions that a user would expect to see? Are any of those core features locked to higher-tiered pricing plans? At its core, we expect a tool to stand up against the baseline capabilities of its competitors.

Standout Features (25% of final scoring)

Next, we evaluate uncommon standout features that go above and beyond the core functionality typically found in tools of its kind. A high score reflects specialized or unique features that make the product faster, more efficient, or offer additional value to the user.

We also evaluate how easy it is to integrate with other tools typically found in the tech stack to expand the functionality and utility of the software. Tools offering plentiful native integrations, 3rd party connections, and API access to build custom integrations score best.

Ease of Use (10% of final scoring)

We consider how quick and easy it is to execute the tasks defined in the core functionality using the tool. High scoring software is well designed, intuitive to use, offers mobile apps, provides templates, and makes relatively complex tasks seem simple.

Onboarding (10% of final scoring)

We know how important rapid team adoption is for a new platform, so we evaluate how easy it is to learn and use a tool with minimal training. We evaluate how quickly a team member can get set up and start using the tool with no experience. High scoring solutions indicate little or no support is required.

Customer Support (10% of final scoring)

We review how quick and easy it is to get unstuck and find help by phone, live chat, or knowledge base. Tools and companies that provide real-time support score best, while chatbots score worst.

Customer Reviews (10% of final scoring)

Beyond our own testing and evaluation, we consider the net promoter score from current and past customers. We review their likelihood, given the option, to choose the tool again for the core functionality. A high scoring software reflects a high net promoter score from current or past customers.

Value for Money (10% of final scoring)

Lastly, in consideration of all the other criteria, we review the average price of entry level plans against the core features and consider the value of the other evaluation criteria. Software that delivers more, for less, will score higher.

Ease of Use

Splunk’s interface is dense and can feel overwhelming for new users, especially those without a technical background. While its search language and dashboard tools are powerful, they require training and experience to use effectively. Many users note that once configured, Splunk offers fast access to insights and flexible customization, but the initial setup and ongoing management demand significant expertise. This makes Splunk best suited for teams with dedicated technical resources.

Onboarding

Splunk’s onboarding process is thorough but can be time-consuming, with many users citing a steep initial learning curve. The platform offers extensive documentation, online training, and an active community forum, which help new users get started. However, configuring data sources and building initial dashboards often requires hands-on support or professional services. This means organizations should plan for a longer ramp-up period before realizing full value from the platform.

Customer Support

Splunk offers responsive customer support with multiple channels, including live chat, phone, and a detailed knowledge base. Users often highlight the expertise of support staff and the value of the active user community for troubleshooting complex issues. Premium support tiers provide faster response times and dedicated assistance, which is especially helpful for enterprise deployments. However, some users mention that resolving highly technical problems can still take time, depending on the complexity of the environment.

Integrations

Splunk integrates with Amazon Web Services (AWS), Microsoft Windows, Google Cloud Platform, Microsoft Cloud Services, Unix and Linux, Salesforce, Okta Identity Cloud, ServiceNow, Cisco ASA, and Jira, among others.

Splunk also offers a robust API and supports connections with third-party integration tools for custom workflows and data ingestion.

Value for Money

Splunk is widely recognized for its advanced capabilities, but many users find its pricing steep, especially as data volumes grow. The platform’s flexible plans suit large enterprises best, while smaller organizations may struggle to justify the cost without significant data analytics needs or technical resources.

Ingest Pricing: Pay based on GB/day of data indexed, with unlimited searches after ingestion.
Workload Pricing: Pay based on compute capacity (SVCs/vCPUs) used for search and analytics.
Entity Pricing: Pricing based on the number of hosts or entities monitored in observability.
Activity-based pricing: Cost tied to activities like metrics, traces, sessions, or uptime requests.
