We prepare and assist organizations in the management of an incident

One eSecurity is a market leading specialist in Threat Detection and Digital Forensics & Incident Response (DFIR) focused on providing services around the lifecycle of a cybersecurity incident. 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.

We assist cybersecurity leaders and work hand by hand with their cybersecurity teams in dealing with countless intrusions and data breaches, from preparation of teams, processes and technology through our cyber-consulting projects and cyberexercises (Readiness), to the early detection of threats through continuous and proactive Threat Hunting services (Detection). We excel in the provision of Incident Response services, whether Emergency (EIR) or not, where we focus on detection, containment, response, eradication and return to normal operations of the company when it has been victim of a cyberattack (Response).

Our clients are spread worldwide, being most of them multinational companies with presence in several countries around the world and many others are Global Fortune 500 companies and government agencies.

We have specialized our operations in the banking, finance, telecommunications, retail and energy sectors, among others, in more than 100 countries and we have permanent technical personnel in Europe, Asia and the Americas.

We are a special trusted partner of the SANS Institute with several SANS Instructors in our Team.
