Building digital trust with Helmes

Security isn’t an add-on – it’s a foundation. At Helmes, we embed security into every step of design, development, and delivery to help our clients operate safely and confidently in a digital world.

Security by Design

We build security into every phase of development – from analysis to audit. With embedded Security Leads, continuous testing, and ISO27001-certified processes, your software is secure by design, not by accident.

Cybersecurity Services

Our experts identify vulnerabilities, validate defences, and guide improvements through penetration testing, threat modelling, and code reviews. You get clear, actionable insights – not theoretical risks.

NIS2 & Compliance

We help you prepare for NIS2 and other security standards through practical, hands-on assessments that uncover risks, validate protection measures, and strengthen your overall security posture.

Clients we helped become more secure

Strengthening OECD’s security posture

The OECD – an international organization of 38 member countries promoting policies for global economic and social well-being – engaged Helmes to assess a critical system managed by a U.S.-based third-party provider. Helmes performed a full-scope security audit, including:

  • Penetration testing (black-box & grey-box)
  • Architecture analysis of networks, data flows & endpoints
  • Infrastructure & configuration review
  • ISO 27001 Annex A compliance evaluation
  • Targeted code review
  • Cryptographic & data protection audit
  • Stakeholder interviews & documentation analysis

Scaling Keyfactor’s enterprise-grade PKI

Keyfactor, a global leader in digital identity security, provides PKI, certificate automation, and secure signing solutions.

Helmes supported secure development of two core platforms:
– EJBCA Enterprise: scalable PKI for certificate management and HSM integration
– SignServer Enterprise: high-performance engine for document, code, and timestamp signing

Work focused on feature development, performance optimization, hardware integration, and compliance with eIDAS, FIPS, and Common Criteria.

Audit of a leading digital bank

A European bank offering digital services to private and business clients engaged Helmes to audit its mobile app for security, performance, and compliance.

Helmes conducted a comprehensive audit covering:
– Security: vulnerabilities and exposure risks (e.g. MITM threats)
– Performance: build quality, technical debt, stability
– UI/UX: usability and accessibility compliance
– Strategy: alignment with the bank’s roadmap

The result: a phased action plan for critical fixes, optimizations, and modernization to boost trust and user experience.
