Thanks, Yaki. Good afternoon, everyone. In addition to providing more color on our first quarter performance and our updated 2023 full year outlook, I plan to focus my time today on our SaaS transition and how the economy continues to affect our customers and in turn, our business. We are pleased with how the team performed during Q1 and are encouraged about what this means for the rest of the year. Although it is early, and we have a lot of work to do, the reception of SaaS from our customers and our sales force, together with our confidence in the pipeline and the ARR uplift we are seeing, allows us to raise both our SaaS mix and our full year ARR guidance. As I discussed in length at the Investor Day in March, ARR, free cash flow and ARR contribution margin are the leading indicators for our business during this transition. The shift from on-prem subscription licenses where approximately 80% of the deal value is recognized upfront to a SaaS model with fully ratable revenue will cause initial headwinds on reported revenue as the SaaS mix increases. However, these headwinds are simply a function of accounting treatment and are not indicative of the trajectory of our transition or of our overall business. In fact, the greater these accounting-related headwinds are, the faster it means we are progressing throughout our transition, which we obviously view as positive. Given the momentum we saw in the first quarter and our pipeline and expectations going forward, we are raising our ARR and SaaS mix outlook, which also means we are adjusting lower our revenue outlook. Our better-than-expected start is being driven by Varonis SaaS, which is resonating with our customers and our sales force. Our first quarter SaaS mix represents 37% of new business and net new upsell ARR, this is our guidance of 15% and the examples that Yaki just discussed are evidence of this reception. Early feedback and the average deal sizes we have seen so far gives us further confidence in the pricing uplift that we previously provided. To that end, during the quarter, some of our reps did decide to go back to deals where an on-prem subscription quote was already put in front of the customer and introduced the SaaS product into the conversation. While some of these did convert, for other deals, it created some near-term disruption and elongated those sales cycles. We think this will work itself out in the second part of this year and is already factored into our guidance. We even saw some existing customers that during the renewal conversations, were happy to convert their entire platform to SaaS and buy additional SaaS licenses. Although the ARR impact of these renewal conversions wasn't material this quarter, it was ahead of our projection. As it relates to our updated guidance, we're not assuming significant conversions or a material change in the dollar value of these conversions versus Q1. But as a modeling note, if these conversions continue to trend ahead of our projections, this will further benefit our North Star metrics, which are ARR free cash flow and ARR contribution margin. At the same time, this would cause a headwind to reported revenue and operating margin, which you should view as a positive in terms of the progression of the transition. As I look at our Q2 pipeline of renewal conversions, it has increased significantly versus Q1, which you should keep in mind as you think through your models. Turning to our sales force. As expected, we did see some turnover, but we are pleased with the engagement of the vast majority of our sales force and their ability to transition to selling SaaS is tracking better than our initial expectations. Further, some of this success is being driven by our learnings from our 2019 transition around setting up programs to reduce friction while providing the right incentives for both the rep and the company. As Yaki mentioned, we believe we have the right solution for the market since Varonis SaaS as allows customers to achieve a faster time to value with significantly lower infrastructure costs. And while it's still early in the year, we feel good about the benefits both our customers and we will achieve as a result of the SaaS transition. In the first quarter, ARR grew 18% year-over-year to $478.1 million and assuming the same SaaS mix as we guided for, we would have been well ahead of our revenue guidance. We generated $35.7 million of free cash flow, which was up from $21 million in the same period last year, reflecting our commitment to top line growth while improving cash flow generation. I'd like to elaborate on what I said earlier regarding the macro environment. During Q1, we saw the slowing economic climate continue to weigh on customers' purchasing patterns. Across the board, we continue to see an elevated level of deal scrutiny and extended sales cycles involving multiple layers of approval, with Europe, in particular, seeing the largest impact. We expect longer deal cycles to continue as a result of ongoing budgetary scrutiny, and our updated guidance already takes this and more into consideration. Turning now to our first quarter results in more detail. Before I get into the numbers, let me remind you of what we've said from the beginning. ARR, free cash flow and ARR contribution margin are the leading indicators for this transition. Remember the shift of our business from term licenses to a SaaS model will make our traditional income statement metrics less indicative of the true health of our business than they have been in the past. We have again included several slides in the investor presentation that illustrate the impact of the transition on various metrics. Now on to the numbers. Q1 total revenues were $107.3 million, up 12% year-over-year. During the quarter, as compared to the same quarter last year, we had approximately a 7% headwind to our year-over-year revenue growth rate as a result of having increased SaaS sales in our bookings mix, which are recognized ratably versus the upfront recognition of our on-prem subscription products. Subscription revenues were $83 million in maintenance and services revenues were $24.4 million as our renewal rates, again, were over 90%. In North America, revenues grew 18% to $81.2 million or 76% of total revenues. In EMEA, revenues declined 5% to $22.9 million or 21% of total revenues. Currency was a 7% headwind in the region. Rest of the World revenues grew 9% to $3.2 million or 3% of total revenue. Just to remind you, reported revenue growth rates throughout all regions were impacted by a higher SaaS mix. Moving down the income statement. I'll be discussing non-GAAP results going forward. Gross profit for the first quarter was $92.9 million, representing a gross margin of 86.5% compared to 85.6% in the first quarter of 2022. Operating expenses in the first quarter totaled $97.1 million. As a result, first quarter operating loss was $4.3 million or an operating margin of negative 4%. This compares to operating loss of $7.9 million or an operating margin of negative 8.2% in the same period last year. During the quarter, as compared to the same quarter last year, we had approximately a 6% headwind to our operating margin as a result of having increased SaaS sales in our bookings mix which are recognized fully ratable versus the upfront recognition of our on-prem subscription products. First quarter ARR contribution margin was 5.6%, up from 4.1% last year, reflecting our ability to drive strong incremental margins while growing ARR and transitioning to SAP. During the quarter, we had financial income of approximately $7.2 million, driven primarily by interest income on our cash deposits and short-term investments. Net loss for the first quarter of 2023 was $0.1 million or $0.00 per basic and diluted share compared to a net loss of $10.2 million or a loss of $0.09 per basic and diluted share for the first quarter of 2022. This is based on $108.4 million and $108.2 million basic and diluted shares outstanding for Q1 2023 and Q1 2022, respectively. As of March 31, 2023, we had $756.3 million in cash, cash equivalents, marketable securities and short-term deposits. For the three months ended March 31, 2023, we generated $36.8 million of cash from operations compared to $24.5 million generated in the same period last year, and CapEx was $1.1 million compared to $3.5 million last year. During the first quarter, we repurchased 100,000 shares at an average purchase price of $25.19, and we have $41 million remaining on our share repurchase authorization. We ended the quarter with approximately 2,150 employees, roughly flat versus last quarter. Turning to our guidance in more detail. Our second quarter and full year guidance now assumes a 35% SaaS mix of new business and upsell ARR, up from 15% previously. A few additional modeling notes on this metric as we look to the back half of the year. First, Federal's largest quarter is the third quarter, and because we are not yet Fed-run certified, we expect this to be a headwind to our SaaS mix in Q3. Second, despite the momentum we saw this quarter, Q1 is still the smallest quarter of the year. And as such, we are taking a prudent approach in building our outlook as the dollar value of deals we expect to close in the second half is much larger than in the first, which is in line with historical trends. And third, we're not assuming significant conversions of renewals from on-prem subscription to SaaS or a material change in the dollar value of these conversions versus Q1. We are raising our ARR guidance, which reflects the faster adoption from our customers to Varonis SaaS. This also results in greater ARR contribution margin, which reflects our ability to focus on operating leverage during the transition. The higher SaaS mix drives corresponding adjustments to revenue and operating income guidance because of the ratable accounting treatment of SaaS versus the upfront accounting treatment of on-prem subscription. Ultimately, we view the update to our guidance as a clear sign that the transition is progressing in a positive direction and continue to view ARR, free cash flow and ARR contribution margin as our North Stars during this transition. Lastly, as a reminder, our guidance continues to factor in headwinds from macro perspective, which includes ongoing budgetary scrutiny, longer sales cycles and an increase in unemployment as well as worsening of other economic conditions. From a SaaS transition standpoint, we are still factoring in a ramp up period in the first half of the year, which assumes increased sales force turnover, lower sales productivity and longer sales cycles as an on-prem subscription deals in flight may convert to SaaS. Now turning to our guidance. For the second quarter of 2023, we expect total revenues of $118 million to $120 million, representing growth of 6% to 8%. Non-GAAP operating income of $0.5 million to $1.5 million and non-GAAP net income per diluted share in the range of $0.01 to $0.02. This assumes 127.2 million diluted shares outstanding. For the full year 2023, we now expect ARR of $520 million to $528 million, representing growth of 12% to 14%. Free cash flow of $20 million to $25 million, which includes a $6 million to $8 million headwind related to the TCJA capitalization of R&D provision. Total revenues of $510 million to $520 million, representing growth of 8% to 10%. Non-GAAP operating income of $29 million to $34 million and non-GAAP net income per diluted share in the range of $0.30 to $0.34. This assumes 126.8 million diluted shares outstanding. In summary, despite continued challenges in the macro environment, the year is off to a solid start with the adoption of Varonis SaaS, showing positive momentum reflected by our first quarter SaaS mix of 37%. These results in our pipeline give us the confidence to raise our full year ARR outlook while driving strong incremental contribution margins. With that, we would be happy to take questions. Operator?
