&lt;p&gt;In October 2023, Systerel received the Security Visa from the French National
Cybersecurity Agency (&lt;a class="reference external" href="https://en.wikipedia.org/wiki/Agence_nationale_de_la_s%C3%A9curit%C3%A9_des_syst%C3%A8mes_d%27information"&gt;ANSSI&lt;/a&gt;)
for the CSPN (&lt;a class="reference external" href="https://cyber.gouv.fr/en/security-visa"&gt;First Level Security Certification&lt;/a&gt;) of its product: &lt;a class="reference external" href="http://www.systerel.fr/en/innovation/products/safe-secure-opc/"&gt;S2OPC&lt;/a&gt;. This
achievement gives us the opportunity to focus on what the &lt;abbr title="Certificat de Sécurité de Premier Niveau"&gt;CSPN&lt;/abbr&gt; is and to
provide feedback on the certification process.&lt;/p&gt;

&lt;p&gt;Back-to-back testing (B2BT) techniques are used to verify that
two products of a software development process are
equivalent. By running the two products "back to back"
on a set of test cases, it is verified that they produce
the same output. If the scenarios are chosen carefully
and the two runs produce the same results, it can be
inferred that the two products are equivalent with some
level of confidence.&lt;/p&gt;
