I can truly say that I have received a 100% service. Jack took the time to call me. He was polite, courteous and attentive to my needs. The best type of service for my needs and within no more than a few hours I had a full report, if you ever need a private investigating service, I would encourage you to use National Private Investigators. Thank you, Jack and your team.

Our TSCM sweeps are not just services; they are a commitment to safeguarding your corporate integrity. By employing state-of-the-art technology and methodologies, we ensure that your confidential discussions remain just that – confidential.

How We Help:

  • Site visit/ evaluation: One of our team of experts will do a site visit to assess your environment, identifying potential vulnerabilities and areas of concern. A quote can then be provided.
  • A two-tier sweep: We meticulously scan your offices, boardrooms, and communication systems for any signs of eavesdropping devices or vulnerabilities. We have a basic sweep and a government level sweep team. To cater for all eventualities.
  • Ongoing contingency sweeps: Espionage threats are ever present and so we offer ongoing support and quarterly annual sweeps to ensure your defence remains impenetrable against any new threat against your business.
  • Training and awareness: Beyond technical sweeps, we teach your team with knowledge of TSCM and data security to recognise and mitigate risks, fostering a culture of security.
