Case studies and stories
Common IT challenges in financial services industry and proven ways to address them
Helmes track record in mission-critical, large scale systems where reliability and security are non-negotiable – 30+ years.
From stalled legacy systems to phased digital transformation with early results
Typical challenges: legacy drag, slow releases, all-at-once full-scale transformation risks.
Helmes approach: phased modernization + fast first iteration to prove value and build momentum, backed by large-organization delivery experience (e.g., ESA portal update shipped quickly as an agile benchmark).
First steps we recommend:
- Digital transformation blueprint (target architecture + phased roadmap).
- Legacy software modernization plan (integrations first, replacements only where needed).
- Initial “value slice” scope + release plan.


Security & Compliance that build resilience
Typical challenges:
- Security added on late -> findings in audits, slow remediation, expensive rework
- Rising phishing/ransomware and mobile/API attack surface
- Hard to prove controls across SDLC (not just policies)
Helmes solution:
- Practical security services (e.g. security audits / penetration testing) to identify and fix critical gaps fast
- Secure-by-design delivery framework: security from architecture through deployment, with continuous security testing, code reviews, and compliance validation built into the delivery flow
- ISO 27001-certified processes + thread modeling to reduce real risk and increase audit readiness
Digital trust: identity, PKI, consent and privacy-by-design
Typical challenges:
- Strong authentication and digital signing are hard to scale securely (keys, certificates, HSMs, lifecycle)
- Privacy and cross-border data handling and complexity (consent, transparency, auditability)
- Zero-trust architectures require robust identity foundations
Helmes solution:
- Digital identity & PKI expertise: national-ID style integrations, PKI platforms, secure signing services, HSM-backed architectures
- Engineering aligned with trust standards (e.g. eIDAS-oriented trust service patterns) and security best practices
- Privacy-by-design systems: consent management, encryption, and audit trails embedded in the platform design
