4code sp. z o.o.

4code is a Poland-based software development and cybersecurity consulting firm founded on the premise that security should be embedded into the development process from day one, not bolted on afterwards. The company operates as a nearshore provider, building and extending teams for clients who need secure custom development, DevSecOps transformation, and security audits. While exact team size isn't stated, 4code positions itself as a multidisciplinary operation with specialists in backend engineering, DevOps, security architecture, and IT recruitment.

The company's core conviction is that treating security as an afterthought is both expensive and dangerous. Rather than selling security as an add-on, 4code advocates for a "SecDevOps" philosophy: integrating security checks, threat modeling, and vulnerability management directly into the software development lifecycle. This means developers adopt security practices as part of their Definition of Done, not as a separate gate.

Services and capabilities

4code offers six main service lines. Secure custom development means building applications with security properties baked in from design phase—confidentiality, integrity, availability, isolation, and least privilege. The company helps teams move from traditional Agile + DevOps to a SecDevOps model where security becomes a first-class concern.

Cybersecurity consulting covers compliance, technical, and organizational advisory. The source notes they maintain expertise across all three areas simultaneously and have experience in both global and Polish markets. This spans architecture reviews, threat modeling, penetration testing, vendor assessments, and infrastructure audits.

Managed teams means 4code staffs an agile team dedicated to a client's project, handling delivery within agreed timelines and budgets. Managed services goes further: the company takes over full project responsibility, planning, quality control, and maintenance under SLAs.

Build-Operate-Transfer (BOT) is a custom model where 4code builds and runs a software development center for the client until it reaches maturity, then transfers full ownership. This reduces risk for clients trying to establish internal capability.

Secure cloud solutions focus on infrastructure design, cloud architecture, and migration. They help clients manage and secure data and cloud services, build hybrid cloud environments with open-source and secure technologies, and optimize DevOps capabilities for cloud workloads.

The company works with GitLab CI, Kubernetes, Google Cloud Platform (GCP), TypeScript, JavaScript, and container security tooling including Static Application Security Testing (SAST) solutions and Advanced Cluster Security scanning.

Notable work

A two-month fixed-price engagement involved a comprehensive cybersecurity audit for a client launching a new application. 4code delivered architecture review, threat modeling, secure development process assessment, penetration testing, infrastructure audit, and vendor assessment. They used manual and automated methods—data flow diagrams, vulnerability identification via STRIDE and DREAD methodologies, OWASP TOP 10 and ASVS frameworks, and DevSecOps maturity modeling. The output was a detailed report with security control assessment and remediation recommendations.

For Urban, 4code built a microservices platform on Google Cloud Platform with TypeScript backend, native mobile, and JavaScript frontend. The platform helps wellness practitioners manage a marketplace and their business operations. The team provided stable team extension with on-call support.

For RailSoft, 4code developed custom reports in the RailSoft system to give field engineers and management visibility into railway data. The team served as technical point of contact, analyzed the system, optimized reports for big-data performance, and reviewed integration options with enova360.

Client testimonials mention efficiency in task execution, technical excellence, successful DevSecOps role embedding, and reliable partnership. Thaumatec Tech Group (via their COO) praised 4code as a partner for extended delivery services. Cargounit noted the thoroughness of detailed deliverables. Bertek highlighted successful DevSecOps implementation and identification of security improvement areas.

How they work

4code engages via fixed-price projects, dedicated managed teams, and managed services under SLAs. The company uses agile frameworks and emphasizes security at each stage of the SDLC—from requirements through maintenance. For audits and consulting, they combine video conferences with detailed information-gathering meetings. They support remote work across geographies and appear to operate without geographic constraints on team composition.

Team and credentials

The company does not disclose headcount publicly in the provided source material. Named team members include Łukasz (backend engineer, based in Malta), Bartek (platform/DevOps/automation focused), and recruitment specialists Zuza and Ania. The company emphasizes hiring for secure development philosophy rather than just technical skills. No formal certifications (ISO 27001, SOC 2, etc.) are mentioned in the source. No partnership status with cloud providers or awards are stated, though they demonstrate hands-on experience with GCP and Kubernetes.

English proficiency appears solid based on website copy and client testimonials, though the company is Polish-founded and operates from Poland.
