A pentest that went beyond the surface
A new authentication layer needed deeper validation. Sunbytes combined manual and automated grey-box testing to uncover and classify vulnerabilities, then guided the team through the findings and remediation options.
Grey-box pentest · SOC 2 & ISO-aligned reporting · 9 findings classified
From concept to a working prototype in 3 sprints
SandGrain needed to turn its post-quantum authentication concept into a secure, scalable cloud platform without compromising reliability. Sunbytes assembled a seven-person multidisciplinary team and delivered a functional prototype in three sprints.
15 releases · 3,380 test cases · 1,777 automated tests
Six weeks from security testing to launch readiness
Methodemeter was preparing to launch a digital education platform without dedicated in-house security expertise. Sunbytes ran a black-box pentest, guided remediation, and aligned testing with GDPR, NIS2 and ISO 27001.
6-week test-to-fix cycle · GDPR, NIS2, ISO 27001 · Launched clean
Web, API and mobile tested before an IPO security audit
C2C needed its production product tested across web, API, iOS and Android before an IPO security audit. Sunbytes ranked each finding and provided remediation guidance the team could act on.

DevSecOps and NIS2: what Dutch companies must do before July 2026
DevSecOps NIS2 readiness means proving that your software development process has working security controls, not just written policies. Before July 2026, Dutch companies in scope for the Cyberbeveiligingswet need evidence for Article 21 controls such as secure development, supply chain security, access management and effectiveness testing. For engineering teams, the practical evidence usually comes from […]

NIS2 penetration testing requirements: what Article 21(2) compliance looks like
NIS2 penetration testing is not a checkbox exercise. Article 21 does not name one single testing tool that every entity must use. It requires organisations to handle vulnerabilities and assess whether their cybersecurity risk-management measures work in practice. That distinction matters. A vulnerability scan can tell you that a known weakness exists. A DAST scan […]

For most EU SMEs, the work does not fail because Article 21 is unknown. It fails because scope, risk assessment, remediation, evidence, and board approval happen in the wrong order. This 12-week plan […]
