Thanks, Mark. I'll now turn to our results in the quarter, which, as a reminder, includes the impact from the acquisition of Vulcan. Calculated current billings defined as revenue recognized in the quarter change in current deferred revenue grew 9% year-over-year to $215.4 million. As discussed earlier driven by Tenable One, including cloud security. Current RPO grew 13% year-over-year, 400 basis points ahead of CCB growth as backlog accelerated during the quarter. During the quarter, we added 361 new enterprise platform customers and our LTM net new six-figure count was 54%. Our net dollar expansion rate was consistent this quarter 108% and our overall renewal rates remained strong. Now on to the P&L for the quarter. Revenue was $239.1 million, which represents 11% year-over-year growth. Revenue in the quarter exceeded the midpoint of our guided range by $5.1 million. Our percentage of recurring revenue remains high at 96% this quarter. Gross margin was 82% this quarter, flat relative to last quarter and in line with expectations. Going forward, we continue to expect gross margins to be in the high 70s to low 80% range. While we are investing to deliver enhanced functionality and analytics to customers, the scalability of our platform has enabled gross margins to remain constant. Sales and marketing expense was $85.5 million, up from $80.1 million last quarter. And as a percentage of revenue, sales and marketing was 36% compared to 34% last quarter. Sales and marketing expense was higher sequentially on an absolute dollar basis and a percentage basis primarily due to costs associated with our annual sales kickoff conference in February, partially offset by lower sales commissions from a seasonally lower renewal base in the quarter. Looking ahead, we expect sales and marketing as a percentage of revenue to be modestly higher in Q2 due to the industry events and other investments we're making, including sales capacity, and trend lower in the second half of the year. R&D expense was $39 million, which was up from $32.5 million last quarter. R&D expense was higher this quarter in comparison to last quarter, primarily due to increased personnel costs, resulting from the Vulcan acquisition as well as the foreign tax credits we received last quarter. As a result, R&D expense as a percentage of revenue was 16% this quarter, up from 14% last quarter. We expect R&D expense as a percentage of revenue to increase in Q2 due to a full quarter of Vulcan costs with improved margins in the second half of the year. G&A expense was $22.7 million, which was up from $20.5 million last quarter, primarily due to compensation expense associated with the passing of our former CEO and pay taxes which reset at the beginning of the year. G&A expense as a percentage of revenue was 9% this quarter, which was flat relative to last quarter. Income from operations was $48.7 million and exceeded the midpoint of our guided range by $7.7 million. Operating margin for the quarter was 20%, which was approximately 300 basis points better than the midpoint of our guided range. We're very pleased with our ability to drive continued leverage in the business while investing for growth. EPS for the quarter was $0.36 a share, which was $0.095 better than the midpoint of our guided range. Now, let's turn to the balance sheet. We finished the quarter with $460 million in cash and short-term investments, reflecting $149 million of net cash used for the Vulcan acquisition. Accounts receivable was $168 million and total deferred revenue was $808 million. Current deferred revenue was $633 million, which gives us a lot of visibility into expected revenue over the next 12 months. We generated a record $87 million of unlevered free cash flow during the quarter. While this quarter's result was influenced by seasonal timing of collections from Q4 sales, we feel confident that we can continue to expand our operating and free cash flow margins over the ensuing years as we have done so every year since our IPO. During the quarter, we repurchased 1.6 million shares of our common stock for an aggregate purchase price of $60 million. In total, we've repurchased almost 4.3 million shares for $175 million since November of 2023 and have $125 million of remaining authorization. Now, with the results of the quarter behind us, I'd like to discuss our outlook for Q2 and the full year 2025. For the second quarter, we currently expect revenue to be in the range of $241 million to $243 million. Non-GAAP income from operations to be in the range of $43 million to $45 million. Non-GAAP net income to be in the range of $36 million to $38 million, assuming interest expense of $7.1 million, interest income of $4 million, and a provision for income taxes of $3.2 million. And non-GAAP diluted earnings are to be in the range of $0.29 to $0.31 a share, assuming 123 million fully diluted weighted average shares outstanding. For the full year, we currently expect calculated current billings to be in the range of $1.25 billion to $1.45 billion. Revenue to be in the range of $970 million to $980 million. Non-GAAP income from operations to be in the range of $205 million $215 million. Non-GAAP net income to be in the range of $178 million to $188 million, assuming interest expense of $28.4 million, interest income of $16.8 million and a provision for income taxes of $13.1 million. Non-GAAP diluted earnings per share to be in the range of $1.44 to $1.52 per share, assuming 123.5 million fully diluted weighted average shares outstanding. And unlevered free cash flow range of $265 million to $275 million. While we're off to a great start for the year and see real momentum in our business, there is clearly more economic uncertainty in the market now than at the beginning of the year. As a result, we are taking an incrementally more cautious approach with our outlook today. Specifically, we extended the cautious first half outlook we provided in February in the US public sector for the remainder of the year. We also acknowledge that recent US policy actions have the potential to reduce visibility in our enterprise business, which could lessen sales cycles. It's important to note that demand creation and top of the funnel remains strong. Our revised guidance today simply reflects the fact that the world is more uncertain and his ability into when deals close has become murkier since we provided our initial guide in February. We believe our updated guidance appropriately balances these potential geopolitical and economic risks and sets us up for success to the remainder of the year. Our guidance for operating income remains unchanged, reflects our emphasis on profitable growth. We expect operating margins to generally increase throughout the year, resulting in an approximate 100 basis point improvement over 2024, even as we absorb the costs associated with the Vulcan acquisition. Notably, our disciplined approach to balanced growth has enabled us to manage the business in a way that allows us to continue to drive strong margins in multiple environments. As a reminder, we typically update our leveraged free cash flow with our Q2 call, but we continue to expect to deliver $265 million to $275 million of unlevered free cash flow in 2025. With that said, Mark and I would like to thank everyone for joining the call today. We're very excited about the opportunity ahead and look forward to updating you throughout the year. We hope to see you at JPMorgan and D.A. Davidson conferences in the coming weeks. And we now like to open the call for questions.
