In a context where software is becoming increasingly strategic and regulated, the Software Assurance Lifecycle (SAL) ensures security, quality, and compliance throughout an application’s entire lifecycle. Regulations such as GDPR, NIS2, and standards like OWASP SAMM and NASA-STD-8739.8B require constant checks and adequate tools. Choosing the right partner can simplify the adoption of secure development processes, reduce operational risks, and improve efficiency.

This article guides you through choosing among the top providers in Italy, comparing features, strengths, and ideal scenarios for every company.
