Who We Are

We prepare and attend organizations in the management of an incident

One eSecurity is a market leading specialist in Digital Forensics and Incident Response (DFIR) company. Our clients trust us for our extraordinary levels of commitment and expertise. We have been on the ‘front-line’ fighting the biggest cyber-crime groups since 2007, being major players in dealing with some of the largest and most complex security incidents and operations ever

Our main goal is focused on the resolution of cybersecurity incidents: analyzing, investigating threats and breaches to contain and eradicate, and recover the systems of any company. Our clients are spread worldwide. Most of them are multinationals which are present in several countries across the world and many others are companies included in the Global Fortune 500 list.

Traditionally we have excelled in the banking sector; however, in recent years and thanks to our experience, we have specialized our operations in other sectors that are also under threat:

  • Banking and Finance
  • Critical Infrastructure/SCADA
  • Telecommunications
  • Energy
  • Construction
  • Law Enforcement
  • Defense and Intelligence
  • Consulting and Law
