A screenshot is not evidence

Anyone can edit a screenshot in a minute, and the other side knows it. That is why, when a case of impersonation, harassment or defamation reaches a Spanish court, loose screenshots are easily challenged. And if the content is deleted in the meantime, the evidence disappears with it.

As a court-appointed IT forensic expert, I certify the content exactly as it is published, using a technical procedure that makes it possible to prove later that it has not been altered.

What we certify

  • Profiles and posts on Instagram, TikTok, Facebook, X, YouTube or LinkedIn.
  • Conversations on WhatsApp, Telegram, email or direct messages.
  • Web pages, forums and comments, with their address and full content.
  • Videos and audio recordings published online.
  • Reviews and ratings when they are part of an attack or a campaign.

How we do it

  1. Forensic acquisition of the content: it is downloaded and documented with tools that record how and when it was obtained.
  2. Digital fingerprint (hash) of each file, which changes if a single character is modified.
  3. Timestamp that proves the date and time of the certification.
  4. Chain of custody documented from acquisition to delivery.
  5. Forensic report, signed and explained in a way a judge can understand, and ratification in court if requested.

When it helps

Identity theft, fake profiles, cyberbullying, threats, extortion, defamation, information leaks or disputes with former employees and former partners. And always before requesting removal: if we remove the content without certifying it, you lose the evidence.

Evidence first, removal second

The usual approach is to combine both jobs: we certify the content so you can report it and then we request its removal from the platform. That way you do not have to choose between taking it down as soon as possible and being able to defend yourself.

We work remotely and in English, with clients in any country, so you do not need to be in Spain to have content certified. Tell us about your case in the free analysis.

Frequently asked questions

How is this different from a notary?

A Spanish notary attests to what they see on screen at that moment. An IT forensic expert also analyses the content technically (origin, metadata, authenticity) and can explain and defend it at trial. In many cases it is more thorough and faster.

Does it work if the content has already been deleted?

It depends. Sometimes copies remain in caches, archives or on the devices themselves (for example, the messages on your phone). Tell us about the case and we will tell you what can be recovered and certified.

Can you find out who is behind a fake profile?

We can provide technical indications to support the complaint. The definitive identification of who uses an account has to be requested from the platform by a court, and the forensic report helps that request succeed.

What is an IT forensic examination?

It is a technical analysis of digital evidence, such as messages, profiles, websites or emails, carried out by an IT forensic expert who issues a signed report. The report explains what was analysed, how, and what conclusions can be drawn, and it can be submitted in court. It is signed by our lead, Javier Arenillas, a court-appointed IT forensic expert with a master's degree in cybersecurity.

When do I need an IT forensic expert?

When you are going to file a complaint or a lawsuit and the evidence is digital: impersonation, harassment, threats, defamation, fake websites or WhatsApp conversations. Also when the other side may challenge your screenshots or when there is a risk that the content will be deleted.

How is a WhatsApp conversation certified?

It is analysed directly on the device and, if necessary, a copy is extracted with forensic tools, calculating a digital fingerprint that makes it possible to prove later that it has not been altered. The report sets out the method, the technical data and the content. A simple screenshot or a transcript cannot offer that assurance.

How long does a forensic report take?

Urgent certification of published content is done within 24 to 48 hours. A full forensic report, with analysis of devices or of several pieces of content, may take longer depending on its scope. We give you a specific timeframe before we start.

How much does an IT forensic examination cost?

It depends on the amount of evidence, whether devices need to be analysed and whether the report has to be ratified in court. You get a fixed quote in writing after the free analysis, before any work starts.

Do I have to go to court with the expert?

You do not have to do anything special. If the court requests it, the expert attends to ratify the report and answers questions from the parties and the judge, as provided for in Spain's Civil Procedure Act (Ley de Enjuiciamiento Civil). That ratification is part of what gives the report its value.

What do I need to commission a forensic report?

The links or the device where the evidence is, and an explanation of the case. If you have a lawyer, it is best that we coordinate with them so the report addresses what the proceedings need. If you do not, we can bring in a law firm we work with when a case requires it.

Is what you analyse confidential?

Yes. We only access what is needed for the report, we store the evidence securely and we do not share it with anyone except your lawyer or the court when appropriate. We will sign a confidentiality agreement if you need one.
