Our eDiscovery litigation team handles all types of electronic data from multiple sources, such as computers, mobile devices, servers, and cloud storage. Using our knowledge of the discovery process and tools, we work diligently to collect and preserve digital files as well as the metadata embedded within them. With our specialists at the helm, you can trust that we’ll provide accurate, defensible solutions for every phase of your discovery process.
The Defense for Early Case Assessment
We offer advanced processes such as Early Case Assessment (ECA) to drastically reduce e-Discovery costs. By performing low-cost data processing on the initial data set, we can limit the data size pushed to review, saving processing costs and costly reviewer time.
The ECA process includes filters for date and keyword, email-threading, near-dup analysis, and culling of system files and unwanted emails to generate high-quality reports. These reports contain refined search terms, email gap analysis, file-type analysis, and more to ensure a quick and efficient review. With these sophisticated e-Discovery solutions, your legal team can spend more time and effort on building a stronger case.

CONTACT USThe e-Discovery Process & What to Expect
Identification
Our e-Discovery specialists consult with attorneys to identify potential sources of ESI, the volume of data that might be discoverable, and the custodians of discoverable evidence. In this way, we can make sure that no valuable evidence is overlooked and that only relevant data is gathered, reducing the risk of unnecessary costs and time spent on irrelevant files.
Preservation & Collection
Once relevant data is identified, it must be preserved in its original state to prevent alteration and destruction (otherwise known as spoliation, which is a sanctionable offense in some cases). Our specialists follow the Electronic Discovery Reference Model (EDRM) and adhere to best practices to guarantee that discoverable ESI is collected and preserved in a forensically sound manner and later admissible in court.
Processing, Review & Analysis
After data is collected, it must be processed to eliminate duplicate files and irrelevant information, making it easier for legal teams to review. For example, data may be converted into a format that is suitable for searching, sorting, and analyzing. Additionally, metadata, such as timestamps and file properties, may be extracted to help establish the context and authenticity of the evidence.
Whether you are responding to a discovery request or complying with a subpoena, we partner with you to process and organize ESI. Specifically, we use Junto.net, our online document review platform, to upload, process, search, and review files seamlessly. We also help you set up a protocol to define precise search parameters within the tool so that you can reduce the volume of information you need to review.
Production
Often in a lawsuit or investigation, attorneys have to respond to a request (or a series of requests) for production. Pursuant to the Federal Rules of Civil Procedure, a party producing ESI must produce the information in a form or forms in which it is ordinarily maintained or in a reasonably usable form or forms. Attorneys can leverage our e-Discovery specialists in this process to prepare and produce ESI in an efficient and usable format to reduce cost, risk, and errors in compliance with agreed production specifications and timelines. This can be done either electronically through secure download links or on encrypted hard drives.

We are trial experts in the technical presentation of evidence for hearings, mediations, arbitrations, and trials.

CONTACT USFrequently Asked Questions
What is considered electronically stored information (ESI)?
ESI is a broad term that encompasses virtually any type of data created or stored in a digital format. Common examples include:
- Emails and attachments
- Databases and application data
- Internal chat and collaboration messages (e.g., Slack, Microsoft Teams)
- Voicemails and text messages
- Social media posts and messages
- Website content and digital photos/videos
- Information stored on servers, laptops, mobile phones, and in the cloud
What is the role of metadata in eDiscovery?
Metadata is information embedded in digital files that provides valuable context, such as who created a document, when it was created, and any changes made to it. In eDiscovery processing, metadata can be vital in establishing the authenticity and timeline of documents or communications. This is why our specialists take extra care to preserve metadata.

What is EDRM?
The Electronic Discovery Reference Model (EDRM) is a standardized framework that outlines the key stages of the e-Discovery process from start to finish. The stages include: Identification, Preservation, Collection, Processing, Review, Analysis, and Production. Cornerstone Discovery uses this model to ensure a comprehensive, defensible, and repeatable process for every matter.
What is a litigation hold (or legal hold)?
A litigation hold is a formal directive sent to key employees (custodians) instructing them not to delete or modify any ESI that may be relevant to a legal matter. It is one of the most critical steps in the e-Discovery process as it prevents spoliation.
What is spoliation, and why is it a major concern during eDiscovery processing?
Spoliation is the intentional, reckless, or negligent destruction, alteration, or concealment of evidence. In electronic discovery, this could be as simple as an employee deleting relevant emails after a litigation hold is in place. Courts take spoliation very seriously, and the penalties can be severe since it undermines the integrity of the legal process.
Can my IT department handle data collection?
While IT departments are experts at managing systems, they are generally not trained in forensic data collection and do not know how to preserve critical metadata (like creation dates and authors) or that they should establish a defensible chain of custody. Instead of risking improper collection methods that inadvertently alter data, making it inadmissible in court and exposing your company to claims of spoliation, hire Cornerstone Discovery for eDiscovery services in PA, NJ, NY, DE, and anywhere else in the United States.
