Scotland achieved their best result since the 2006 RBS 6 Nations this year, repeating the finish of seven years ago by ending third in the table as Wales defended their title.
They bounced back from defeat to England in their opening fixture of the Championship to run in four tries in a 34-10 win over Italy in the first of three games at Murrayfield.
Despite following up on that with a 12-8 victory over Ireland, Scotland scored just one more try in the Championship, that coming in their final match a 23-16 loss to France in Paris.
And, while praising the steps made by the Scotland's defence which conceded 93 points in three autumn international fixtures last year, Visser doesn't want the attack to get forgotten.
"The strange thing about this campaign for us was that I spent more time defending than attacking, especially in the Ireland game," said Visser - who scored two of Scotland's seven tries.
"If you looked at the stats they had all of the ball. It was unbelievable. But our defence has had to improve, and it has done.
"If you look back to the autumn and where we are now, you can see all the work our defence coach Matt Taylor has done with the individuals and the team as a whole.
"We are now a better defensive unit. In the autumn we would not have been able to handle a lot of the stuff that has been thrown at us. Now the next step is for us to keep hold of our own possession."
