Yet with Munster still to face next up before a final-day trip to the Warriors' Scotstoun fortress, Henderson insists his side cannot afford to let their intensity drop.
And with this year's GUINNESS PRO12 Final taking place at Ulster's Kingspan Stadium, the 23-year-old admits there is extra incentive to extend their current unbeaten home record in the league to the whole season.
"I don't think any team relishes coming here and that is one thing we are really proud of, to think that this is our fortress," Henderson told the Belfast Telegraph.
"We strive to keep it a fortress, and it's our goal to make this the toughest place to win for any GUINNESS PRO12 or European team coming here.
"We knew the run-in was going to be tough but we want to get the home semi-final secured because we know we have the home final.
"Munster are a big front-up side, they are very forward orientated and also have very sharp backs.
"We need to dominate them up front and as we've seen earlier in the season if we don't dominate up front we can't get the front-foot ball we need to show what we can do."
