4Safe is an Italian engineering company focused on cybersecurity, digital forensics, secure software engineering, enterprise software development, security research, infrastructure engineering, and DevSecOps.
We build commercial software, internal security tooling, and operational systems with a practical emphasis on correctness, maintainability, and security from the first design decision.
Our mission is to design and operate software systems that remain reliable under real-world security, compliance, and operational pressure.
We work at the intersection of software engineering and security: architecture, backend systems, evidence handling, infrastructure automation, defensive tooling, and secure delivery practices.
- Security by design: threat modeling, least privilege, secure defaults, and explicit trust boundaries.
- Privacy first: data minimization, clear retention policies, and careful handling of sensitive information.
- Clean architecture: readable boundaries, testable components, and long-term maintainability.
- Open standards: preference for interoperable protocols, documented formats, and portable infrastructure.
- Operational discipline: observability, repeatable deployments, backups, incident readiness, and measurable reliability.
- Code quality: clear reviews, focused tests, simple abstractions, and documented tradeoffs.
- Security assessment support and automation
- Secure software architecture
- Vulnerability analysis workflows
- Infrastructure hardening
- DevSecOps practices
- Security research tooling
- Evidence acquisition workflows
- Case and evidence management systems
- Chain-of-custody support
- Incident investigation tooling
- Technical reporting systems
- Enterprise web applications
- ASP.NET Core services and APIs
- PostgreSQL-backed systems
- Background processing and integration services
- Cloud and on-premises deployments
- CI/CD and infrastructure automation
The organization contains a mix of commercial products, internal tools, and research projects. Public repositories may include:
- 4Safe Platform: security service platform components.
- 4Safe Recon: reconnaissance and validation tooling for authorized targets.
- Digital forensics systems: software for evidence workflows, reporting, and operational case support.
- Infrastructure and DevSecOps tooling: automation used to build, secure, and operate systems consistently.
Availability varies by repository. Some work is private because it contains customer-specific logic, internal operational tooling, or security-sensitive implementation details.
We commonly work with:
| Area | Technologies |
|---|---|
| Backend | .NET, C#, ASP.NET Core, REST APIs, background services |
| Data | PostgreSQL, Redis, object storage, structured audit trails |
| Infrastructure | Linux, Docker, Caddy, reverse proxies, system hardening |
| Delivery | GitHub Actions, CI/CD, reproducible builds, deployment runbooks |
| Security | secure coding, vulnerability management, logging, monitoring |
| Observability | structured logs, health checks, metrics, traces |
We value contributions that improve security, correctness, maintainability, and clarity. Good contributions are scoped, reviewed, tested, and documented.
Before contributing to a public repository, read its local CONTRIBUTING.md,
SECURITY.md, and issue templates. If a repository does not define local
community files, the organization defaults in this repository apply.
Security issues must not be reported through public issues. See
SECURITY.md for responsible disclosure.
