// 01 — WHY PROSEC DEFENSE
Cyber security built on operational, investigative and intelligence experience
ProSec Defense GmbH is not a conventional cyber security company. Our expertise stems from decades of experience in military, intelligence and law-enforcement cyber environments – where attacks are not assessed in the abstract, but must be understood confidentially, operationally and under time pressure.
Within the ProSec Group we unite highly specialized hackers, incident responders and digital forensics experts into one team that understands attacks, interprets traces reliably and enables decisions in critical situations.
We combine DFIR, Threat Intelligence and Security Hardening into cyber security that does not merely advise, but holds up when it matters and takes effect preventively.
// WHAT SETS US APART

From analysis to hardening
DFIR, Threat Intelligence and Security Hardening combined into resilient cyber defense.
// 02 — SERVICES
Cyber defense services – modular and mission-oriented
Hybrid attacks require different capabilities – from rapid incident response to preventive hardening and the assessment of current threat situations. That is why our services are modular and mission-oriented, aligned to your situation, risk and need for action.
DFIR & Incident Response
When systems are compromised, we support forensic analysis, containment, situational assessment, recovery and post-incident monitoring.
- Digital Forensics & Incident Response
- Containment and recovery
- Post-incident monitoring
Resilience Ops & Security Hardening
We identify attack paths, prioritize technical risks and guide the operational hardening of critical systems, identities and configurations.
- Resilience Ops program
- Security hardening
- Attack surface reduction
Cyber Threat Intelligence
We analyze threat situations, relevant threat actor groups, attack patterns and technical indicators to prioritize security measures more precisely.
- Threat landscape & trend analysis
- Risk and security prioritization
- Proactive threat hunting
Post Incident
After containment we work through the incident in a structured way: root-cause analysis, lessons learned, lasting hardening and audit-ready documentation for management, regulators and insurers.
- Realistische Prüfung
- Context over isolated findings
- Risk-based testing strategy
// 03 — METHODOLOGY
Four phases – clear, repeatable, auditable
A process that aligns technical teams and stakeholders – with clear outputs per phase.
1
PHASE 1
Discovery & Scope
Objectives, systems, data sources, responsibilities.
Result: scope, communication plan, quick-win list.
2
PHASE 2
Telemetry & Controls
Ensure logging/EDR/cloud signals, establish hardening baselines.
Result: a reliable data foundation.
3
PHASE 3
Detection & Tuning
Build use cases, validate alerts, reduce noise.
Result: fewer false positives, higher alert fidelity.
4
PHASE 4
Response Readiness
Playbooks, roles, exercises.
Result: rehearsed procedures, fast decisions during an incident.
