Thank you. As Amit mentioned earlier, we are pleased to cap the year on a very positive note with strong top line growth and operating margin. I will provide more commentary momentarily. But, first, please note that all operating results we discuss today are non-GAAP financial measures with the exception of revenue. As Erin mentioned at the start of this call, GAAP to non-GAAP reconciliations may be found on our earnings release issued earlier today. As a reminder, our financial results reflect the results of operations from Ermetic, which closed October 2. Now on to the results for the quarter. Calculated current billings, defined as revenue recognized in the quarter plus change in current deferred revenue, grew 14% year-over-year to $271.6 million and benefited from Tenable One which was 22% of total new sales. Exposure solutions, which include Tenable One, as well as standalone sales of cloud security, identity security and operational technology security, represented 50% of our total new enterprise sales. This reflects the continued traction in our exposure management platform and our ability to help customers translate asset, vulnerability and threat data across IT and OT assets, cloud resources, web apps and identity platforms and to business insights and actionable intelligence. As expected, Ermetic contributed minimally to CCB as our primary focus was integrating the two cloud security product platforms in Q4. As I've mentioned on prior calls, CCB is typically a close, but not perfect, proxy for sales in the quarter and is influenced by a number of factors, such as mix of business, deal timing, including early renewals. Notably, CCB in the quarter was more closely correlated to current RPO growth of 16%. In terms of key metrics, we added 597 new enterprise platform customers in the quarter, inclusive of Ermetic customers, which is up sequentially from the 386 we added last quarter. Mid-market stabilized this quarter and produced modest CCB upside, helping them select new platform customers higher. In terms of large deals, we added 156 net new six figure customers in Q4, and that numbers more than 2x higher than what we reported last quarter. Our dollar based net expansion rate was 111% in the quarter, and is consistent with last quarter. And as a reminder, the expansion rate is calculated on an LTM basis. Revenue was $213.3 million, which represents 16% year-over-year growth. Revenue in the quarter exceeded the midpoint of our guidance range by $7.3 million. Revenue from Ermetic was less than 1% of total revenue in the quarter, which was derived primarily from the acquired deferred revenue. Our percentage of recurring revenue remains high at 95% this quarter, which is consistent with prior periods. I'll turn to expenses now. Let's start with gross margin, which was 81% this quarter compared to 80% last quarter, and approximately 250 basis points better than expected. As previously discussed, we are integrating Ermetic public cloud infrastructure into ours. While this process introduces some additional costs, the progress out of the gate has been strong and exceeded our initial expectations and helped drive margins higher in the quarter. Gross margin for the full year was 80%, consistent with last year. Looking ahead, we continue to expect gross margins to be in the high 70s, low 80% range as we add new intelligence and functionality to Tenable One and our standalone cloud security offering. Sales and marketing expense was $88.5 million, which was up from $79 million last quarter. Sales and marketing expense as a percentage of revenue was 41% compared to 39% last quarter. Sales and marketing expense is seasonally higher in the fourth quarter, and increased sequentially, primarily due to increased personnel costs, incremental investments in marketing to build our brand, and higher sales commissions and variable compensation attributed to our strong sales performance and renewal base in the quarter. For the full year, sales and marketing expense as a percent of revenue was 42%, down from 44% last year, representing a 240 basis point improvement. R&D expense was $27.8 million, which was flat compared to last quarter. R&D expense as a percentage of revenue was 13% this quarter compared to 14% last quarter. R&D expense increased sequentially, primarily due to increased personnel, public cloud costs and Ermetic facility costs that was offset by foreign R&D tax credits. For the full year, R&D expense as a percentage of revenue was 14% compared to 16% last year. G&A expense was $19.5 million, which was up from $18.5 million last quarter. G&A expense as a percentage of revenue was 9% this quarter and flat relative to last quarter. G&A expense was 9% for the full year, down from 10% in 2022. We will continue to make investments in G&A on an absolute dollar basis to support the growth and scale of our business. Income from operations was $36.1 million, which was significantly better than expected and exceeded the midpoint of our guidance range by $12.6 million. Operating margin for the quarter was 17%, which was 550 basis points better than the midpoint of our guidance. The sizeable upside in earnings this quarter reflects the strength of our business model and our ability to cost effectively acquire customers and expand those relationships over time. Operating margin for the full year was 15%, which was a 520 basis point increase from last year, and is 400 basis points better than our expectations going into the year. It also represents a very significant increase from 6% operating margin that we reported in 2020, and reflects our ability to effectively balance growth with profitability, all while investing in expansionary TAM opportunities, including executing on a successful M&A strategy. All of this resulted in EPS of $0.25, which was approximately $0.115 better than the midpoint of our guided range. Now, let's turn to the balance sheet. After paying $243 million net cash for Ermetic, we finished the quarter with $474 million in cash and short term investments. Accounts receivable was $220.1 million and total deferred revenue was $750.5 million, including $4 million of acquired deferred revenue from Ermetic. Current deferred revenue was $580.8 million, which gives us a lot of visibility into revenue over the next 12 months. We generated $43.3 million of unlevered free cash flow during the quarter and $175.4 million for the full year, which is up from $128.1 million last year. With 95% recurring revenue, high gross margins and renewal rates, we feel confident that we can continue to expand our operating margins and free cash flow margins over the ensuing years. Also in November, we announced a $100 million share repurchase program pursuant to which we repurchased 356,000 shares of common stock, with an aggregate purchase price of $14.9 million. We are taking a programmatic approach to partially offsetting our share creep and we'll continue to evaluate the size of the program going forward based on valuation of our common stock as well as other factors. With the results of the quarter behind us, I'd like to discuss our 2024 outlook. For the first quarter, we currently expect revenue to be in the range of $212 million to $214 million, non-GAAP income from operations to be in the range of $27 million to $29 million, non-GAAP net income to be in the range of $20 million to $22 million, assuming interest expense of $8.2 million, interest income of $5.2 million and a provision for income taxes of $3.9 million. Non-GAAP diluted earnings per share to be in the range of $0.16 to $0.18, assuming 123 million fully diluted weighted average shares outstanding. And for the full year, we currently expect calculated current billings to be in the range of $982 million to $992 million, revenue to be in the range of $895 million to $905 million; non-GAAP income from operations to be in the range of $152 million to $160 million; non-GAAP net income to be in the range of $129 million to $137 million, assuming interest expense of $32.2 million, interest income of $21.7 million and a provision for income taxes of $10.6 million; non-GAAP diluted earnings per share to be in the range of $1.03 to $1.10 a share, assuming 125 million fully diluted weighted average shares outstanding; and unlevered free cash flow to be in the range of $220 million to $230 million. Now, I'd like to provide some commentary regarding our outlook today. Our CCB guide represents a range of 12% to 14% growth for the full year, which is consistent with the directional comments I made during our last call. In terms of quarterly flow, we expect growth to accelerate modestly during the course of the year as we finalize the Ermetic product integration and continue to build pipeline opportunities for our more expansive CNAPP offering. Our guidance tonight also reflects an operating margin in the 17% to 18% range, which at the midpoint is a 220 basis point improvement over the prior year. We also expect to follow the same seasonal spending patterns as prior years, with incremental investment more weighted in the first half of the year, resulting in higher operating margin in the second half of the year. This is a strong initial guide for the year, which is benefited by the optimization plan Amit spoke of earlier. Accordingly, I want to provide some clarifying remarks on the model impact of the restructuring costs. It's worth noting that we recognize $4.5 million of these costs in the fourth quarter and expect to recognize an additional $2 million to $3 million in the first quarter related to the reduction in force that took place in January. Further, we are currently in negotiations to sublease a portion of our real estate, which could result in a non-cash impairment charge of $6 million to $7 million, bringing total restructuring expenses to $12.5 million to $14.5 million. Please note that all restructuring expenses are excluded from our non-GAAP results. And in terms of cash flow for 2024, our guidance includes a $6 million to $7 million reduction for the cash outlay related to the restructuring charges. While these charges will not be given pro forma treatment for cash flow purposes, such amounts should be taken into consideration when determining the normalized cash flows of the business. It's also worth noting that our guidance of $220 million to $230 million of unlevered free cash flow represents a doubling from the initial guide of $120 million to $125 million that I provided on our October 2022 call when considering the $10 million to $15 million of dilution associated with the Ermetic acquisition. Looking ahead, we expect unlevered free cash flow margin to generally ramp through the year, with Q2 as the typical seasonal low point. Also, as a reminder, we do not plan to update our free cash flow guide quarterly as the timing of collections and payments can vary from quarter to quarter. Our next update is expected to be mid-year on our Q2 call. At this time, I'd like to turn the call over to Amit for some closing comments.
