Investigations & evidence · employee and leaver enquiries

Workplace investigations, Exeter. The client list left a week before they did.

The pattern repeats itself: files funnelled into a personal cloud account, a USB stick used at some ungodly hour, and a laptop returned to you looking suspiciously like new. As for digital evidence of all of it, this is usually left behind. We then recover it (lawfully) through prompt, secure handling and examination of the device to an evidentially acceptable standard. This will allow you to present a credible written report to both HR and your legal representatives.

Where the evidence hides.

The USB trailWindows will quietly log every single storage device that has been added to the system, along with a timestamp. A thumbdrive stuck into the PC at one in the morning, two days prior to when notice went in, will be telling its own story.
Cloud and webmail exitsCloud-based storage services including Dropbox, OneDrive and Google Drive, as well as personal email accounts, generate historical evidence that remains even after attempts have been made to clean their digital footprints. The histories, sync databases and upload fragments generated by these applications may also provide additional evidence that cannot be easily deleted.
Wipers and mass deletesIf someone uses a wiping tool to remove data from a device, the fact that they ran a wiping tool (and which one), how long they ran the wiping tool for, and, tellingly, the areas where the wiping tool did not delete data will all still appear in the artefacts that remain.
The timeline is the caseAlthough any single piece of evidence is deniable on its own, combining them (folder staged, stick attached, data uploaded, wiper run) provides a tribunal with a clear trail of what happened and in what order.

Staying on the right side of the law.

What's neededThe practical effectOur answer to it
UK GDPR / DPA 2018A lawful basis is needed for accessing even a device owned by the company. This would typically be under the 'legitimate interests' legal basis, but it must always be proportionate and properly documented.The scope remains as narrow as possible: the data collected is based only on the level of justification for suspecting wrongdoing.
The ICO's monitoring guidance, October 2023By default, transparency is required. However, a Data Protection Impact Assessment (DPIA) needs to be completed if the risk level is high.First we review your company's policies. Then, we determine if an assessment is necessary and let you know.
Covert examinationThere are to be very few occasions when this can happen, i.e. when criminal activity or a serious breach of professional conduct is suspected, and then only with senior authorisationWe will not commence the process until we see that signed document in front of us.
ACAS expectationsAll disciplinary actions must be based on a reasonable and impartial investigation.Our examination is carried out independently; no one edits the findings of our examination.
How tribunals weigh itThe probative value of the material collected is weighed against the method used to collect the material.Custody records that support and enhance the evidence rather than undermine it.
Posting it to us: first of all, get a quote, either via a telephone call or using the quotation form. Once you have obtained your quote, please deliver your kit and media to our intake laboratory in Bristol using tracked and insured post. We will cover the return postage to you once processed. Alternatively, you may also personally drop the items off at our laboratory, Monday to Friday, 9am to 5:30pm, with no appointment needed. Are you unsure of sending methods? Please ring us first and we will be happy to suggest the safest method for your specific job (we do not collect). More information is available on the contact page.

01

Talked through in confidence, quoted in writing Free

When you instruct us on a new matter, we will first hold a confidential conversation about what has occurred, which devices/accounts matter and what the evidence needs to establish. Following this, you will receive a single written quote, fixed prior to any examination commencing, and the initial scope of works does not incur any cost.

02

Secure the device fast

Once your laptop, desktop computer or loose hard drive is placed behind a write blocker, it will be imaged in a matter of days. This imaging process occurs before any reissue or rebuild process takes place and before anyone else who may have access to your equipment destroys evidence.

03

Follow the data out

This image has details of activity relating to USB connections, synced data from the cloud, history of webmail access, patterns of deletion as well as any use of wiping tools. This information will be put together in one timeline indicating what left, at what time it left, and via which route.

Exfiltration routes tracedDeletions put in order
04

Write it up properly

We create a clear and detailed written report regarding your case. It is created in a format suitable for both HR and legal purposes. Throughout this report we have considered guidance provided by the ICO in their 2023 monitoring guidance and the standard expected of a fair investigation according to ACAS.

Drafted for tribunal useICO & ACAS aligned

Captured, documented, court-ready

You get everything: the report, all of the exhibits and the files behind each exhibit, as well as the hashes, the continuity record and our working notes. If at some time in the future a tribunal or another expert wishes to verify anything, they will be able to follow the entire chain of evidence from start to finish.

Rules the bench works by

  • IT rebuilds are the single greatest threat to your ability to gather evidence. More cases are destroyed when a departing employee's laptop is wiped clean for the new user who will take possession of it than by all deliberate attempts at hiding evidence combined.
  • Nobody edits the examiner's report: investigations have been criticised at tribunals when HR directed the findings, therefore our reports come to you in their exact form.
  • Vendor survey statistics exaggerate: surveys citing percentages of departing employees who take data can range anywhere from one-third upwards; assume the direction is accurate and view any precise numbers beyond that as marketing.
  • BYOD is a different field: a person's own laptop would need consent or very solid legal grounds before it could be examined (we do not examine phones or tablets), and we will establish this boundary with you first.

A single number that has credibility: in a 2013 Symantec/Ponemon study, approximately half of recent former employee respondents admitted to keeping confidential information from their previous employers. More recent percentages are mostly generated by vendors and have varied significantly. Bench experience is simpler; if an employer already believes data walked, then artefact agreement typically follows.

The client list slipped out three weeks ahead

The initial tip-off was a competitor's pitch deck that landed on the desk of an employer in Barnstaple. Next came a series of digital timelines which told a story in itself: a single folder collecting all of the documents, access to a personal cloud account by signing in, then finally the uploads were completed, all twenty days prior to any resignation letters being sent in. Undertakings shut it down quickly.

Before it leaves your hands.

Do

  • Collect the unit, turn off the unit and do not touch it any further.
  • Before the account is deactivated (which will delete the mailbox), you need to preserve the mailbox and accounts.
  • Find out what your company's policies actually told employees regarding monitoring their use of computer systems.
  • Get senior-level management written approval before doing any type of covert activity.

Steer clear

  • Allow IT to erase all information from the system and reissue the device.
  • Review files on the system prior to securing them in order to find out whether or not this is a valid case.
  • Contact the employee directly about it before proceeding to secure any data on the computer system.
  • Conduct covert monitoring without having any exceptional circumstances documented as justification.

Asked in private, answered plainly.

Can my employer inspect my work laptop?

Yes, generally speaking: provided that a lawful basis for examination existed and that employees were aware that an examination could occur based upon an acceptable-use policy. Covert examinations are relatively rare. They require authorised permission at the senior levels and are limited to situations involving possible criminal conduct by the employee, or serious breaches of employee discipline.

Is covert monitoring legal in the UK?

Rarely. The ICO's October 2023 advice states that covert monitoring can only take place under extraordinary conditions (suspected crime being the classic case), with senior approval of the monitoring, with limited scope for the monitoring and with a formal record of the monitoring.

Suspect a leaver walked off with data — first move?

Just put the device in a safe place and don't touch anything. Don't shut down their accounts or remove any of their contents, and have the device imaged prior to anyone in your organisation looking into it. The reason for this is that even if you merely browse through the files, you will destroy the traces as to how the information was removed.

Will the evidence stand up at tribunal?

When tribunals assess the usefulness of materials versus the methods used to obtain them, these three elements will make the difference between a folder full of screenshots and evidence which actually carries real weight: a lawful basis for obtaining the material; the scope of the investigation or access remaining proportionate; and evidence collection activities being properly documented as part of a chain of custody.

Evidence fades fast. Don't hang about.

When recorders overwrite on a loop, all recorded evidence will weaken and time limitations expire, so open your case now. The first review is completely free and confidential.
