ISASecure and IEC 62443, explained with the numbers
What each certification program actually evaluates, how the security levels and device types change the scope, and where the common points of confusion come from — written by the assessors who run these evaluations.

Independent testing in ISASecure CSA: what the lab must test itself
ISASecure CSA flags 34 of its 166 functional requirements for testing by the lab itself. What the flag means, what happens to the rest, and what to prepare.
ISASecure vulnerability identification testing: how the pass threshold scales with security level
ISASecure VIT pass criteria: one severity band is added per security level, the scan is identical at every level, and a pass never requires zero findings.
Cloud links, wireless radios and the per-interface rule in ISASecure ICSA
In ISASecure ICSA, cloud and wireless links are ordinary accessible interfaces. How the per-interface rule and the untrusted-network declaration set the effort.
IIoT vulnerability testing: how ISASecure ICSA's two tiers set the pass threshold
ISASecure ICSA vulnerability testing: Core must address critical and high findings, Advanced adds medium. One scan, two filters; a pass is never zero findings.
Independent testing in ISASecure ICSA: the 47 requirements the lab exercises
ISASecure ICSA flags 47 of its 182 functional requirements for testing by the lab itself, 40 of them at Core. What the flag means and what to prepare.
SSA SDA-S artifacts: the 74 lifecycle rows ISASecure checks for a system, and why fuzz and load results are among them
ISASecure SSA's SDA-S stream re-checks 74 assessable rows of the SDLA-312 lifecycle catalogue for the system as sold, fuzz and load coverage included.
ISASecure SSA vulnerability testing: the scan where each zone sets its own pass threshold
How VIT-S works in ISASecure SSA: one known-vulnerability scan of every IP-addressed component, with the pass threshold set per component by its zone's level.
Independent testing in ISASecure SSA: eleven flagged requirements, one scan, one reference system
ISASecure SSA flags 11 of its 116 assessable rows for lab testing, plus one vulnerability scan on one reference system. What the lab tests and reviews.
