Compromise Assessment · Forensic analysis

Know whether attackers are already inside your systems.

A compromise assessment surfaces active and historical attacker traces in your environment — across endpoints, logs, identities and infrastructure. Before an undetected compromise turns into a full breach.

The problem

Your security stack can miss invisible attacker activity.

Even mature organisations with firewalls, EDR, SIEM and regular penetration tests miss advanced attackers. Persistent threats often go undetected — and the longer they stay hidden, the more expensive the damage.

A compromise assessment is built to surface exactly the traces that traditional controls don't bring clearly enough to the surface. It clarifies whether suspicious signals are isolated anomalies, historical artifacts or indicators of an active attack.

Definition

What is a compromise assessment?

An expert-led forensic investigation that hunts your environment for traces of attacker activity — both present and historical.

Focus on traces

Unlike a vulnerability scan or a pentest, a compromise assessment hunts the leftovers of an attack: indicators of compromise, suspicious processes, persistence mechanisms, unusual access patterns.

Tool & analyst

Tool-driven collection of artifacts — files, registry, processes, event logs — combined with manual validation by experienced analysts. No blind trust in automation, no pure gut feel.

A clear answer

What you get is not a hypothesis but a graded, documented answer: were traces found? Where? How widespread? What priority do they need?

When it fits

When a compromise assessment makes sense

Four typical situations where the factual basis of a compromise assessment makes the difference.

Active incident
Faster analysis, faster recovery. When the question „Are we still compromised?" needs an answer right now.
Proactive check
Before traces grow into an open incident. Clarity on whether undetected attacker activity is already present.
Before audits & certifications
Defensible evidence on your current security posture. Facts instead of assumptions — especially for ISO 27001, NIS2, KRITIS or DORA reviews.
M&A & integration
Don't carry dormant compromises or sleeping malware into a merged environment. Adds the forensic angle to cybersecurity due diligence.
How it works

How we work.

Four structured phases — from alignment through analysis to a documented recommendation.

1
Scoping & rollout
Systems, data sources and technical prerequisites are defined. Agents and tools are prepared, interfaces clarified.
2
Collection & scan
Endpoint, log and infrastructure data are collected. Telemetry, traffic and event logs are checked against relevant indicators of compromise.
3
Analysis & validation
Suspicious artifacts are assessed manually by analysts. Real findings are separated from noise — no false positive is left untouched.
4
Report & action
Documented findings, prioritised by risk. If active compromise is confirmed, a seamless handoff into Incident Response.
What you get

What you receive.

Concrete, defensible deliverables — not generic compliance documents.

A clear posture statement
An unambiguous assessment of whether signs of compromise were identified — and if so, to what extent.
Affected-systems overview
List of suspicious assets, anomalous behavioural patterns and the relevant indicators of compromise.
Evidence-based recommendations
Risk-prioritised actions — containment, cleanup, hardening — directly executable by your team.
Handoff into Incident Response
If active attacker activity is detected, we move seamlessly into an Incident Response engagement — without losing context.
Distinction

Not every security analysis answers the same question.

Vulnerability assessment, penetration test and compromise assessment complement each other — they don't replace one another.

Find weaknesses
Vulnerability Assessment
„Where are our weaknesses?"
  • Tool-driven identification of known vulnerabilities
  • Broad coverage of the attack surface
  • Answers the where, not the how far
Test exploitability
Penetration Test
„Are these weaknesses exploitable?"
  • Active, controlled exploitation by testers
  • Proof of practical risk impact
  • Answers the how, not the has it already happened
Surface real traces
Compromise Assessment
„Have they been exploited — and are attackers still inside?"
  • Forensic search for real attacker traces
  • Historical and present view of the environment
  • Answers the whether, the what and the what now
