Proof Finder FrEquently Asked Questions

What Is Proof Finder?

In December 2011, Nuix released a software product called Proof Finder. It is a philanthropic venture to raise money for a fabulous and worthwhile charity, Room to Read. Our original aim was to raise $100,000 by giving individuals and companies the chance to access the power of Nuix for a fraction of the normal price, with 100% of their payment going to this charity.

To date, money raised by Nuix through Proof Finder has resulted in a new school building being built in Nepal, funds transferred to support the building of a new school building in Sri Lanka, the publication of 9,000 local language books in Nepal and fund has been allocated to sponsor 30 girls through school.

Proof Finder is a limited version of Nuix’s desktop investigation software that allows individual users to undertake any number of small cases (up to 15GB) for a token price of $100/year. The vast majority of cases undertaken by law enforcement officers, government officials, lawyers, HR managers and in-house investigators are quite small and this product would be an ideal solution for them. Proof Finder enables individual users with small cases to get the benefits of Nuix’s advanced eDiscovery and electronic investigation software for a fraction of the cost.

Why are you selling Proof Finder for $100 per year, when your other products start in the thousands?

Proof Finder is a philanthropic software offering which enables Nuix to give back to both the legal and investigation community and also to help children in the developing world. As a successful global business, we believe we have a responsibility to do this.

With Proof Finder, investigators and lawyers all over the world have the chance to buy the most advanced electronic discovery and investigative technology to help them solve their puzzles and crimes. Even though the size of their investigations might be small in terms of Nuix’s normal application, it can still be incredibly difficult to find evidence without good eDiscovery and electronic investigation technology. Lawyers and investigators will be able to quickly find proof regarding a range of issues, including fraud, inappropriate behaviour and images, child abuse and intellectual property leaks.

Because of our position of having created such advanced eDiscovery and electronic investigation software, we have an opportunity to help real people with real problems that would never be solved without the application of technology. We have priced Proof Finder at just $100 per year to remove the barriers for this community.

And at the same time, every Proof Finder license sold raises much needed funds for Room to Read. For every license sold, we give 100% of the purchase price to Room to Read.

Room to Read is a charity that helps improve education in the developing world by establishing libraries and schools, publishing local language books, sponsoring the education of girls, organizing reading programs, and more.

How does Proof Finder compare to other Nuix solutions?

While Proof Finder does not have the same processing power of Nuix's enterprise offerings, it processes data at between 2-6 GB per hour, depending on the user’s hardware configuration and has significant search capability. This processing speed is still an order of magnitude faster than most forensic investigation toolsets that are sold for many thousands of dollars, while also providing Nuix's unparalleled ability to search text, metadata images, deleted and encrypted data as well as files which have been modified to hide their identity.

Proof Finder has many of the same search and analysis capabilities as any Nuix eDiscovery and electronic investigation solution. It can interact with all the various email and forensic formats and exports into native files. Proof Finder has a limit of 15 GB expanded file of data that it can investigate per case, but it can be used across any number of cases per year. The vast majority of cases around the world come under this limit so it is an ideal desktop tool for an individual investigator or lawyer working on many small cases.

What will Nuix do with the $100?

Nuix donates 100% of the payment for every Proof Finder license sold to Room to Read. Nuix absorbs all of the transaction costs incurred in processing the payment as well as support, training and administration costs. Rather than distributing small amounts of money to a number of organizations, Nuix has chosen to support a single non-profit organization which is profoundly changing the world by educating children. Over seven million children have benefitted from Room to Read’s programs over the past ten years. Read more about Room to Read.

Do I have to be a computer forensics examiner to use Proof Finder?

No. Many people from all professions need the ability to investigate data in an environment that protects the data being investigated. Proof Finder protects your data while you search and review it.

What are the key features and benefits of Proof Finder?

Proof Finder provides powerful, easy-to-use workflows to help you make sense of data faster, even with the largest and most complex eDiscovery and investigation tasks. Our advanced searching and analytical tools give you rapid insights into the evidence, so you can drive strategy, make informed decisions and save time and money.

Deep forensic analysis: Proof Finder includes all the capabilities required for in-depth forensic analysis of disk images, including recovering deleted files, carving unallocated space and unidentified data items, fully indexing and navigating Windows Registry files and a hex viewer to analyze files and file fragments.

Visualize, analyze, report and automate: Proof Finder’s Visual Analytics framework provides hundreds of ways to visually explore your data, making it easier to detect trends and isolate outliers across multiple evidence sources and formats. You can also create and modify workflows to automatically cull, search, tag and manipulate data, and generate powerful, customized reports.

New features for Proof Finder 4.2: The latest version of Proof Finder includes support for Cellebrite and Micro Systemation XRY mobile device images; Android device call, voicemail and message databases; Autonomy IDOL IDX files; and deeper metadata extraction from Linux and Mac OS file systems.

What are the key benefits for people doing eDiscovery?

Proof Finder is a powerful and intuitive solution for eDiscovery processing, investigation, analysis, review and production. It enables you to rapidly find and act on critical evidence for litigation, compliance and regulatory matters, while minimizing costs.

Finds Facts Fast: Proof Finder uncovers the key evidence faster and more comprehensively than any other technology. We help you find the custodians, communication threads, documents and metadata that will decide the case and quickly get to the heart of the matter. Lawyers, analysts and investigators with minimal training can start using Proof Finder in minutes to find relevant evidence.

Make an informed case assessment: In the same time it takes your opponents to evaluate the quantity and make-up of their data, Proof Finder enables you to assess the strengths and weaknesses of your case. You can set the best case strategy at the outset and maintain a leading edge throughout litigation.

Simplify complex data sets: Proof Finder rapidly and directly indexes complex data sets such as Microsoft Outlook PST and OST files and Lotus Notes. We have an unmatched reputation for processing and searching the most complex data sets so you can unlock critical evidence.

What are the key benefits for people doing investigations?

Proof Finder offers all the capabilities you need to triage, process, analyze and bring to the surface critical evidence across complex data sets. Our technology automatically identifies intelligence such as email and IP addresses and phone, social security and credit card numbers.

Content-based forensic triage: Investigators can use multiple data management, analytical and forensic techniques to focus on the most critical sources until the key evidence emerges. Nuix has the only technology currently available that can manage this entire process.

Investigate all sources at once: Proof Finder can extract data from hard drives, smartphones, tablets and memory cards, as well as cloud services such as Hotmail and Gmail accounts, and corporate repositories such as email servers, email archives, collaboration systems and file shares.

Extract and correlate intelligence: Proof Finder automatically extracts and cross-references intelligence items such as names, companies, sums of money, email addresses, IP addresses and identity, phone and credit card numbers. This can reveal connections across multiple data sources and investigations.

Would any of your existing customers be able to substitute Proof Finder for their existing Nuix solution?

Proof Finder is not a replacement for Nuix as it doesn’t have anything like the speed, power, scale, review or export capabilities. However, it is a perfect solution for individuals who need to undertake small (sub 15GB) investigations and it could also be used to expand the number of people in an organization who use Nuix, simply by keeping the quantum of data that needs to be reviewed to under 15GB and utilizing Nuix Enterprise's "sub-case export" functionality.

What products does this compete with in the marketplace?

Nuix is not trying to compete with anyone in the market for this product. The small case/individual lawyer and investigator community is a group which is underserviced and mostly ignored by the commercial marketplace. This is largely because they are hard to identify and in general they have significant budget limitations for technology.

Also, if they are individuals within large companies or government departments, the sales cycles take so long that it is difficult to justify the effort. Nuix thinks there is a need for this kind of desktop software to enable organizations to resolve electronic investigations quickly and efficiently. And we are proud to be able to provide this tool, with 100% of the proceeds going to a worthwhile organization that is educating children in developing countries.

Why are you giving all of the proceeds to charity?

Because we can. Nuix has hundreds of customers in over 35 countries, many of whom are large and successful public and private organizations. It is very important to the management and employees of Nuix that we find ways to care for the communities we exist within and also to find ways to make the world a better and smarter place – to play our part in changing lives for the better. Proof Finder gives us the chance to do both, and we are both passionate and proud of the product and what it has achieved since we launched in December 2011.

Is this a hidden introductory price offer?

No, Proof Finder is just $100/year and we are committed to a $100 price point for the foreseeable future, and also to this being a product that raises money for charity. All people who purchase Proof Finder (or who have purchased in the past) will be able to repurchase Proof Finder when their 12 month license expires for $100.

What happens if a user goes over the 15GB file size?

Proof Finder will not work on file sizes above 15GB. When the case size limit is reached Proof Finder will display a message screen which will indicate that the user has exceeded the threshold and will not open the case. To use the data a user would need to index a smaller amount of data.

I am an HR manager or an investigator in a larger company. Is Proof Finder right for me?

If the quantities of data you are investigating are under 15GB and the evidence is in the data set, you will be able to find what you are looking for with Proof Finder quickly and easily. If you have larger cases greater than 15GB, you should speak to a Nuix expert to help you define your requirements.

What happens if a company wants to purchase a large number of Proof Finder licenses for their staff to use?

Companies with large Proof Finder requirements should contact Nuix at sales@nuix.com and an expert can review the request and assist to make the most efficient purchase and licensing arrangements.

Who uses Nuix software?

Nuix is a worldwide provider of information management technologies, including eDiscovery, electronic investigation and information governance software. Nuix customers include the world’s leading advisory firms, litigation support providers, enterprises, government departments, law enforcement agencies and all of the world’s major corporate regulatory bodies.

Does the purchase of Proof Finder include a tax deductive donation receipt since the proceeds are going to charity?

Unfortunately not. The reason is that people are actually purchasing the license and Nuix is making the $100 charitable donation on their behalf.

What is the Proof Finder License?

  1. An annual license for Proof Finder software
  2. Includes 12 months support, maintenance and upgrades
  3. Acceptable for commercial use by a single user of a single computer
  4. Supports 15GB cases only; you cannot combine multiple cases over 15GB
  5. Proof Finder is locked (or licensed) to your computer so if you change computer you will need to repurchase Proof Finder
  6. Changing the time clock on your computer will invalidate the license

What happens after one year?

Proof Finder will stop working after 12 months when the license expires. To continue using the software, receiving software updates and to have access to technical support, users will need to repurchase their license for $100. The software has an inbuilt reminder mechanism that will alert you of pending expiry, plus the license holder will be contacted by email prior to the expiration of the software to remind them.

How is the training delivered?

A series of demonstration and training videos are on the Proof Finder website training page.

Can you give me some use cases for where Proof Finder would be useful?

Law enforcement: An ever increasing number of cases revolve around data that has been seized through the collection or forensic imaging of laptops and hard drives. Law enforcement members are particularly burdened with email investigations. Proof Finder provides a simple way for users and investigators to interact with individual people’s files very quickly, through a simple yet powerful user interface.

Lawyers: Proof Finder gives lawyers the ability to interact with their clients’ data on their desktop. A client may come in and hand over their case data, and within a matter of an hour or two, using Proof Finder, the lawyer could easily undertake an initial early case assessment. Proof Finder would enable a lawyer to become intimate with the case and case data in the shortest possible time. This would include not just the text, but also the metadata, which often identifies what is true from what is false. It is a great way for lawyers to start to get used to eDiscovery technology as a powerful and strategic tool in their legal strategy.

In a Deposition: Where the person being deposed is using internet mail, Proof Finder would allow for the web based mail account to be harvested on the spot, by connecting to the internet and downloading the Gmail/yahoo/Hotmail data. All of the mail could be processed and made searchable in minutes. This has recently been used very successfully in employee disputes.

Company investigation: Whether the smallest or largest company, if you need to investigate one or two PST (email) files along with some electronic documentation for any number of issues (pornography, intellectual property leaks, fraud, inappropriate behaviour) – Proof Finder will enable you to find the evidence if it exists in the data set.

My Proof Finder License is not activating my software, what do I do?

We have noticed some people having issues once they receive their Proof Finder license key and they attempt to activate their software.

We believe this to be issues with different mail systems removing parts of our email. When you paste your key into the registration window please double check that it has the following format:

  • Ensure you are copying and pasting the whole key including -----BEGIN LICENCE----- and -----END LICENCE----- .  Please note that there are 5 dashes at the start of these lines.
  • There is a blank line between the PFNXAxxxx number and the first line of the license key text: For example,

If you have chosen to run Proof Finder on a Virtual Machine, please ensure you read our technical FAQ for running Proof Finder on a Virtual Machine.

If you still experience issues with activating your software using your emailed Proof Finder license key please contact pf-support@nuix.com.

What happens if a case goes over the 15GB limit?

Nuix calculates the size of a case as the fully expanded size once all documents have been extracted from compression files, such as .zip files.  Proof Finder will not work on expanded file sizes above 15GB. When the case size limit is reached, Proof Finder will display a message which will indicate that the user has exceeded the threshold and Proof Finder will not open the case.

If your data is larger than 15GB you have two options: break the data down into smaller (sub-15GB) chunks for processing, or click here to contact Nuix to discuss your requirements with a Nuix Sales representative.

What does 15GB of data look like?

Proof Finder has the capacity to investigate up to 15GB per case. For one payment of $100 you can undertake as many cases of up to 15GB of expanded (uncompressed) data per case as you like for one year.

As a guide this means you can process and search between 80,000 and 350,000 emails - excluding containers or system files - per case. Older data sets will typically be smaller than current ones. This is however only a guide. The number of emails and items in the 15GB will depend largely on factors such as data type, compression of data, attachments in emails, and many other factors. Click here for more information.

How many cores is Proof Finder licensed for?

Proof Finder 2 is a basic dual-core license.

Can purchasers try before they buy?

No. We are developing a number of demo videos on this site for you to view, and we will be running regular webinars to demonstrate the tool and train people in how to make best use of it in their investigations. See Training for more details.

Does the product come with a dongle?

No, once a purchaser has downloaded Proof Finder and paid for it, a license key will be automatically generated through our system and emailed to you. This license key is connected with the computer you will use Proof Finder on. The license is not transferable to another computer or another user.

How do I get upgrades?

Nuix is constantly upgrading its software and Proof Finder customers may want to upgrade to the latest release.

In the same email we send to you with your Proof Finder License Key, we will include the URL of our Customer Portal, as well as a unique username and password. Upgrades can be downloaded and installed from here in minutes. There is also a range of training and documentation available for customers to use.

You will be notified via email when a new release is available.

I haven’t been emailed my license key after purchase, what do I do?

Your Proof Finder license key should be emailed to you within 30 minutes of purchasing to the email address you supplied. Please check your spam filter in your email program in the first instance if your email fails to arrive. 

To allow for Internet issues beyond normal business control, if you key does not arrive, please allow up to 3 hours to pass and then email pf-support@nuix.com outlining the details you used for purchasing, including the name, company name and email address used to purchase.

What happens if I change my system clock?

Proof Finder is valid for 12 months from the date of purchase. If your machine's system clock is turned backwards prior to the time you last logged in during this 12-month period, you will receive an error message telling you that your license is not valid.

This is part of the security features of Proof Finder. The license will rectify itself once the current time on the machine is changed to be later than the last time you logged in. This security feature cannot be released by support technicians so it is best avoided if possible.

What if my computer that has Proof Finder installed fails during my license period?

As this is a charity initiative, should your machine fail or be reassigned, your license will no longer be valid as it is only issued to that machine. It is advisable that this situation is planned for as much as possible.

How do I create a set of system diagnostics to provide to technical support?

To create System Diagnostics within Proof Finder, click Help > System Diagnostics and save the .zip file created.

This should be done while the issue is occurring. For example, they can be collected while ingesting data, or straight after a task, after exporting for example.

These logs tell Support what was happening in Proof Finder at the point the issue occurred, as well as some limited information regarding the current environment Proof Finder is running in.

Should your diagnostics .zip file exceed the maximum limit your mail server will allow you to email, please email pf-support@nuix.com and we can provide a secure location to upload the logs.

Can Proof Finder decrypt encrypted files?

Proof Finder can find and identify encrypted documents and often extract metadata but is not able to decrypt encrypted files.

Can I open Proof Finder cases with other Nuix licenses?

If you are currently a Nuix customer you will not be able to open any Proof Finder cases with any other normal Nuix license unless it is audited.

Can I install Proof Finder on a Virtual Machine?

Proof Finder can be installed and used on a virtual machine (VM) as long as the configuration of the VM is static during the license period of Proof Finder. By ensuring your VM is configured as desired with cores and memory prior to installing Proof Finder it will ensure that there is no change in machine ID which will invalidate your Proof Finder license.

Please note that we have found that even reverting back to previous settings on a Virtual Machine will generate a completely new machine ID for the VM which will still not be valid with your original license of Proof Finder. A validation of a Windows license may change the machine ID after validation so it is advised that this is done prior to installing Proof Finder.
