Because the pattern is not anchored at either end the string 'SSL Certificate' will never match.

$ perl -le'
my @strings = (
    "SSL",
    "SSL Certificate",
    "VASCO",
    "something else",
    );
for ( @strings ) {
    print $1 if /(SSL|SSL Certificate|VASCO)/;
    }
'
SSL
SSL
VASCO

With no anchors you need to put the longer strings first:

$ perl -le'
my @strings = (
    "SSL",
    "SSL Certificate",
    "VASCO",
    "something else",
    );
for ( @strings ) {
    print $1 if /(SSL Certificate|SSL|VASCO)/;
    }
'
SSL
SSL Certificate
VASCO

That's a good point, but in the OP's use case it's irrelevant. In fact, the regex could be trimmed down to: `/(SSL\|VASCO)/` Or, to avoid unnecessary capturing: `/(?:SSL\|VASCO)/`	[reply] [d/l] [select]
