What is the expected revenue growth rate for PING in 2021
rowth. This is the second consecutive quarter you have had over 30% growth on a year-over-year basis. So can you just talk about how your products have evolved and what might be driving that inflection and growth?
Andre Durand -- Chief Executive Officer
Andy, this is Andre. Thanks for the question. Our product platform, the PingOne Cloud Platform is reaching a level of maturity. Now it's a combination of our Advanced Services coming online Q4 of last year, combined with several new services, some acquired some built organically, like Risk, Fraud, Verification, and those services coming online line as well. So it -- the story here really is the maturation of the Ping Cloud Platform being offered to existing customers, as well as new customers.
Andrew Nowinski -- Wells Fargo -- Analyst
Okay, great. And then, I want to ask about some of the recent acquisitions, including SecuredTouch in June and then now Singular Key here in September. How do you think those acquisitions fit into this product evolution, where your platforms headed to them? How should we think about the inorganic contribution from those acquisitions in 2022?
Andre Durand -- Chief Executive Officer
We have always had a vision that identity needs to be intelligent, informed by risk and fraud signals to make better authentication and authorization decisions. So SecuredTouch is consistent with that. We had introduced PingOne Risk, which was a risk service for our workforce use case earlier in the year. SecuredTouch completes that by offering risk and fraud signals now for the customer and consumer use case. So the entire notion that we are building a virtuous cycle, where risk and fraud signals inform the identity control plane how to behave. It's also instrumental toward our password list vision, there is no way to achieve a password list experience without leveraging the implicit signals that are available to us, such that if risk is low and trust is high, we just let the user in, so to speak. So that acquisition was part of our strategy around an intelligent identity control plane.
The Singular or this -- yes, the Singular Key acquisition is a little bit different. If you step back identity is an integration game. We are trying to connect everyone to everything, speed of integration, time to value and the flexibility with which companies can actually integrate, not just the basic, but the more advanced identity technologies is critical to all of these large enterprises. Singular Key allows us to achieve a 10x on the time to value and the speed to integration. And it does so because much of the historical coding, as we say, the point-to-point hard coding has all been done in now Singular Key. So it allows the business to design user experiences without coding. So identity is an integration game, time to value, speed to integrate really matters, Singular Key allows us to orchestrate all of these identity experiences without coding.
Andrew Nowinski -- Wells Fargo -- Analyst
That's great. Any color on how we should think about their contribution in 2022 or is still too early?
Raj Dani -- Chief Financial Officer
Yes. Hey Andy, this is Raj. It is a little early. We are just a couple of weeks and a couple months into the -- into these integrations. So our first order of business right now is to integrate them with our own SaaS platform and continue to build pipe. What I will tell you is that, there's a ton of excitement from our customers, from our sales force, and just generally in the marketplace around these solutions; so just watch the space.
Andrew Nowinski -- Wells Fargo -- Analyst

Adam Tindle -- Raymond James -- Analyst
Okay, thanks. Good afternoon. I wanted to start on ARR. Last year you had just over $250 million and based on guidance this year, it's going to be just over $300 million. So I look at the new ARR that you are adding about $50
