How We Chose the Best eDiscovery Software

eDiscovery software is electronic discovery software used by legal professionals to review, process, and tag electronic data and documents, such as emails, text messages, social media posts, and computer files. They use the information discovered to prepare electronic documents for investigations and lawsuits. eDiscovery software digitizes the process, making it much quicker than manually going through all this data. There are numerous eDiscovery software companies, and all tout multiple features and services. We evaluated these companies on important eDiscovery features, integrations, and reports to create our list.

eDiscovery Features

An average civil case can involve 130 gigabytes of data, which is equal to 6.5 million pages of data. With the right features, eDiscovery makes the process of gathering, processing, and indexing all this data much faster and more accurate. We recommend software that comes with a variety of features for eDiscovery, especially document indexing, full text extraction, and keyword search.


eDiscovery must be able to leverage other technologies to be effective. The best software has pre-built integrations for tools that are often used together with eDiscovery software. We looked for software with key technology integrations that improve the exchange of up-to-date information, including integrations with HR systems, case management software, and other enterprise data sources and IT investments.


Good eDiscovery software often includes various pre-built reports, such as summary reports that monitor case progress to ensure resources are properly allocated and deadlines met. Activity reporting is also valuable to create an audit trail for all users’ actions, and life cycle reporting covers the entire eDiscovery process from collection through production. Detailed reports help the user understand and improve the performance of their discovery process, so we focused on companies with robust reporting built into their software.

What Is eDiscovery Software?

Electronic discovery, or eDiscovery, software takes care of the electronic aspect of identifying, collecting, reviewing, and tagging all types of electronically stored information. These platforms provide the tools that legal professionals need to process electronic information, including emails, chat sessions, instant messages, social media posts, word processing documents, digital audio and/or video recordings, cell phone data, GPS data, and all other types of digital records. Legal teams use the processed data to produce documents that may be used in investigations, subpoena responses, litigation, compliance matters, and other legal proceedings.

Unlike hardcopy evidence, electronic data and documents are more dynamic and typically contain metadata, such as author and recipient information, time-date stamps, and other file properties. To use electronically stored information in legal proceedings, the original content and the metadata must be preserved to eliminate claims of tampering. Besides uncovering the data and processing it for review, eDiscovery software preserves this data and creates an audit trail to prove the data was unadulterated. The sheer volume of electronic data produced and stored by people makes it nearly impossible to process this data for legal proceedings without the use of eDiscovery software.

Benefits of eDiscovery Software

Collecting, reviewing, tagging, and organizing electronically stored information in complex legal cases is extremely time-consuming without the help of eDiscovery software. This software automates the entire process, making it much more efficient and reducing costs. Because legal teams often have limited time for eDiscovery, one of the biggest benefits is the time it saves. Some of the many other benefits of eDiscovery software include:

  • Avoiding eDiscovery sanctions: When discovery is handled incorrectly by legal teams or not completed in the timeframe given, legal sanctions may occur. These risks can be mitigated with eDiscovery software.
  • Identifying gaps: Gaps may exist between dates where there should be documents and point out that some electronically stored information has been deleted. eDiscovery software searches for gaps to identify what’s missing from a production, which might otherwise be overlooked.
  • Performing auto-redactions: This is a version history feature that ensures all the original content of a document remains preserved and searchable. It also makes sure an audit trail of the redaction is retained for legal purposes.
  • Advanced search: eDiscovery software has the technology to enable advanced search features, such as tagging and metadata, making it easier to focus on specific keywords and other parameters.

Must-Have Features for eDiscovery Software

When identifying eDiscovery software must-have features, technology integrations should top that list. The right integrations empower legal teams to coordinate activities efficiently and give users immediate access to search for and collect data for eDiscovery projects. Integrations can preserve custodian data, prevent users from deleting information relevant to a legal matter, and transmit data between applications accurately. Other important must-have features include:

  • Document indexing: Associates documents with keywords so they can be more efficiently searched for review
  • Keyword search: Helps narrow down the content produced to find relevant details to export for the case and reduces the amount of content that needs managed
  • Full-text extraction: Scans entire files and runs optical character recognition so they can be indexed and searched
  • Metadata extraction: Extracts and stores all the metadata attached to electronically stored documents
  • Topic clustering: Groups related information together so users can review the clusters provided and search for common patterns or themes that run through the electronic documents
  • Case analytics for reporting: Analytics provide the tools for data mining and event tracking to create reports that provide insight and analysis for document review

The Cost of eDiscovery Software

eDiscovery costs depend on multiple factors, including how complex the review is and the size and type of data being processed for the review. The type of eDiscovery solution used also factors into the cost. Performing a completely in-house review using legacy software eliminates data storage fees but requires firms to purchase the equipment required to house this data. An in-house review using a cloud-based provider solves the storage problem, but most charge upload fees that can add up. Upload and download fees are very common and usually charged on a per gigabyte basis. These fees are above the monthly subscription fee, which is the most common way eDiscovery software providers charge for using their platform.

Like any product, choosing the cheapest provider can cost more in the long run. Inferior eDiscovery software can slow the discovery process, expose legal teams to court sanctions, and leave data vulnerable to hackers. Compare costs along with company reputation. While most of the companies on our list don’t provide public pricing information for comparisons, the average monthly costs were between $295 and $495. Hosted eDiscovery systems with a subscription-based fee structure must also meet Federal Rules of Civil Procedure regulations.
