The manager said his side have set the standard as a double from Alfredo Morelos and a goal from Malik Tillmans secured all three points in the Scottish Premiership.
Speaking to RangersTV at full-time, Beale said: “I thought we were at it defensively today, I thought Hearts picked a bold formation to attack us and we picked a bold formation to attack them as well.
“All around the pitch our pressing was the best it has been, we regained the ball in some really dangerous areas, and we were quite ruthless, on another day we might've scored one or two more. We are really pleased with the clean sheet and I was able obviously to make some changes in the game as well so overall it is the strongest performance yet.
“That is six away wins on the bounce so that is something we can be proud of, but I just said to them we have set a standard now and I don't want us to come off of that.”
Beale believes it was a real team performance, as he praised the squad for their approach to the match. He continued: “You know it is tough here and I thought the fans were up and it was a really good game. The teams went at it but on the night our forwards were really clinical. I thought Fashion [Sakala], Alfredo [Morelos] and Ryan Kent particularly were good with Malik [Tillman] breaking out of midfield. I was delighted all round, I thought the full-backs had big games so it was a real team performance and I am delighted for them.
“We have been asking the players to run in behind more and risk the ball in behind more so when we are getting caught just offside, I don't mind it so much because you will get in. Obviously, Fashion did get in on one for Alfredo to make it 3-0 so I am delighted.
“There were some big chances missed again as well so it is not like we are only creating three chances that we are scoring, we are creating a lot more than that.”
The manager hopes his squad can continue to push on moving forward as they build on tonight’s performance.
He continued: “Hearts have been in fine form and everyone is talking about them at the minute positively and I think that is fair as well because they have been playing ever so well but I thought it was a strong performance from us tonight.
“That is near to the standard I want. It's not the standard I want, I still want the team to push on and show more but that is certainly closer to the Rangers I want us to see regularly.”
