Compromise Assessment

Compromise Assessment

Many organizations assume they are secure simply because no alerts are firing. In reality, sophisticated attackers often remain undetected for months, silently moving through systems and collecting sensitive data. There are contexts — when different companies in the same sector have suffered multiple attacks, or in situations of global technological instability or threats of different origins (political, economic, etc.) — in which the level of concern about potential attacks increases. For business leaders, the critical question is: “Are we already compromised without knowing it?”

A Compromise Assessment provides clear, evidence-based assurance. It identifies whether attackers have already gained access, whether traces of past intrusions remain, and where hidden threats may still be active. The result is confidence in your current security posture—or immediate insight into urgent risks that require attention.

DEFION’s solution

DEFION’s Compromise Assessment is a structured analysis of your systems designed to uncover signs of intrusion, both past and present. By reviewing logs, artifacts, and security telemetry, our experts detect indicators of compromise (IOCs) and adversarial techniques (TTPs) that may have bypassed existing defenses.

This service delivers not only technical findings but also strategic clarity for executives, answering the key question: Is our organization compromised, and if so, what should we do next?

If required, DEFION can tailor the assessment to focus on particular subsidiaries or network segments, helping you understand and manage risks that span across your entire organization.

Methodology

Our assessment follows a four-phase approach:

1. Access – Secure access to SIEM/EDR consoles and, where needed, forensic agents.

2. Identification – Search for IOCs and TTPs linked to potential compromise.

3. Acquisition – Collect artifacts and logs needed for forensic validation.

4. Analysis – Perform in-depth review of evidence to confirm or rule out compromise.
