What it solves

What matters, explained with clarity.

Detecting identity impersonation fraud requires visibility and control over who is actually accessing your systems. Relying only on usernames and passwords is no longer sufficient.

  • Access from unusual locations or devices are warning signs.
  • Use of valid credentials at unusual times or patterns may indicate fraud.
  • Lack of additional authentication makes impersonation easier.
  • Lack of monitoring prevents suspicious behavior from being detected.

The essentials, clearly explained

Identity impersonation turns an attacker into a “legitimate user.” Without proper controls, fraud goes unnoticed.

Designed for companies handling sensitive data or critical access. If you do not verify who is behind each login, you are exposed.

How we work

Intervene in a discreet, practical, and effective. way

1
Understand the context First, it is necessary to analyze how identities and access are managed: how users authenticate, what controls exist, and whether there is visibility over access. Without this, fraud cannot be detected.
2
Identify signs of identity impersonation Key questions: are there logins from unusual locations? Are suspicious credential changes detected? Are there repeated failed attempts? Are access events to critical systems monitored? This is where possible fraud is detected.
3
Turn findings into decisions Direct action: implement multi-factor authentication, continuous monitoring, anomalous behavior alerts, and strict verification policies. This allows fraud to be detected and blocked before causing impact.
