Thanks, Amit. Let me now dive deeper into Tenable's third quarter 2018 financial results and our business outlook. I'll begin by reminding you, that except for revenue, all financial results we will discuss today are non-GAAP, unless otherwise stated. As Andrea mentioned at the start of this call, GAAP to non-GAAP reconciliations of these financial measures can be found in our earnings press release issued earlier today. Revenue for the quarter was $69.4 million, representing a 42% growth over the same quarter last year, and it’s also above the high end of our guided range. Revenue was higher than expected due in part to better calculated current billings in the quarter as well as strong intra-quarter flow. Its also worth noting that 89% of our revenue in Q3 was recurring which is a benefit of our subscription model. As you may recall, we include revenue from subscription and maintenance contracts in recurring revenue but exclude professional service and perpetual license revenue in this definition as such amounts are not available for future renewal. Since we are on the topic of perpetual licenses, as a reminder, under ASC 606, we recognized revenue from perpetual licenses ratably over five years versus revenue recognition upfront previously. I briefly mentioned our subscription model earlier. But once again as a reminder, we sell our software primarily on an annual subscription basis with a term that is generally one year and less, although some customers prefer multiyear contracts. Substantially all of our contracts are paid upfront. The value of a contract can be based on the number of IPs or assets purchased. Now with that as a backdrop, I want to walk you through our calculated current billings. Since swings in the percentage of billings for multiyear prepaid contracts can meaningfully skew growth in total billings higher or lower in a given period, we believe calculated current billings is a better proxy of the underlying momentum of the business and generally correlates to annual contract value or ACV, which is how we manage the business. Calculated current billings, defined as the change in current deferred revenue plus revenue recognized in a period, grew 35% on a year-over-year to $86.7 million in the third quarter of 2018. This growth in scale is a testament to the growing strategic importance of VM and the broader Cyber Exposure opportunity that we are addressing. For Q3 in particular, which is the end of the US government's fiscal year we are very pleased that federal contributed over 20% of our total billings in the quarter. This is consistent with our continued position and strength this market. Now while fed sales do seasonally trend higher in the quarter, the third quarter, fed typically represents less than 15% of our total annual billings. Amit highlighted earlier our success in the federal market, but in short, we are very pleased with our growing presence in this important sector. In addition to the public sector, let's discuss some other growth drivers for the quarter. In simple terms this comes down to winning new customers, retaining customers and growing the value of our relationships with customers. In the third quarter, we added 258 new enterprise platform customers, which is relatively consistent with last year. While we had a strong quarter with expansions in our customer base we added a significant number of new enterprise logos in the quarter and we believe there is a long runway to continue to do so. Given our continuing focus to land and expand larger deals in the enterprise market, it is natural to expect some level of variability between volumes and deal sizes on a quarter-to-quarter basis. As it relates to large deals, we had 387 customers spending in excess of $100,000 in annual recurring revenue on an LTM basis, at the end of the third quarter, which is up 79% over the same period last year. Within this category, we also added a higher number of 500,000 to seven figure customers as compared to recent quarters. This resulted in an increase in ASPs for our new enterprise business in the quarter. The takeaway here is that we're seeing strong demand in the market and are experiencing continued momentum from new customer acquisition, upsell and renewals. I'll now turn to expense and profitability. Gross margin for the quarter was 84%, down from 85% in Q2 but came in better than expected. As previously discussed, we are making investments in our public cloud infrastructure in connection with our Tenable.io cloud platform. These investments are currently scaling better than expected. So gross margin has been contracting more gradually than anticipated, even in IO continues to grow as a percentage of sales. However, we do expect gross margins to settle in to low 80% range to high 70% range over time. Now, turning to operating expenses we are focused on improving operating leverage in our business over the long-term, but in the near-term we are investing for growth. Sales and marketing expenses for Q3 were $41.8 million compared to $29.2 million in the third quarter last year. This represents 60% of total revenue for the quarter, consistent with Q3 last year and an improvement from Q2 levels. Our investments in building a global sales organization tend to be weighted towards the beginning of the year, which produces leverage over time as new members of our sales team ramp the productivity. R&D expense in Q3 was $18.1 million compared to $15.4 million in Q3 last year. As a percent of total revenue R&D was 26% in the most recent quarter versus 31% in Q3 last year. Innovation remains a top priority for us across all of our products, but especially around data science, analytics and coverage of new paradigm assets, including OT, web app, cloud and containers. For Q3, we've also capitalized $600,000 or approximately $1.5 million year-to-date related to the development of Lumin. G&A expense was $10.3 million for the quarter compared to $6.2 million last year. As a percent of total revenue, G&A was 15% in Q3 versus 13% in Q3 last year. The increase largely reflects the occurrence of public company costs. Our non-GAAP loss from operations in the quarter was $12.2 million, better than our guidance of a loss of $17.5 million to $16.5 million and compared to loss of $9 million in the third quarter last year. Non-GAAP operating margin was negative 18%, consistent with the third quarter last year. Pro forma non-GAAP loss per share was $0.14, also better than our guidance of a loss of $0.19 to $0.18 and compared to a loss of $0.12 in the same period last year. The pro forma weighted average shares assumed preferred shares outstanding before our IPO were converted to common stock at the beginning of all periods presented. As a reminder, we are using pro forma shares for historical periods and guidance solely for comparability purposes. We finished the quarter with $287 million in cash and cash equivalents and short-term investments having closed our IPO in July. Our free cash flow burn was $2.9 million for the quarter compared to a burn of $1.9 million in the third quarter of 2017. We started our ESPP program in August, which contributed approximately $2.3 million towards free cash flow in the quarter. The first stock issuance under the ESPP program will be in March of 2019, which will reduce our free cash flow by approximately $8 million to $9 million in Q1, but we believe we will have -- it will have minimal impact on the overall free cash flow for the full year 2019 as the second half of the year will reflect proceeds from the new offering period. In short, we’re pleased with the efficiency and cash flow of the business and we continue to target positive cash flow till the time we exit 2020. Now, turning to guidance. For Q4 2018, we currently expect revenue to be in the range of $72.5 million to $73 million. Non-GAAP loss from operations to be in the range of $14 million to $13 million. Non-GAAP net loss to be in the range of $13.6 million to $12.6 million. And pro forma non-GAAP loss per share in the range of $0.15 to $0.14, assuming a weighted average shares outstanding of 92.2 million. For the full year 2018, we currently expect revenue of $264.6 million to $265.1 million, which is up from our prior guidance of $260 million to $261 million. We are also increasing our annual guidance on calculated current billings. For the full year 2018, we expect calculated current billings of $321 million to $322 million, which is up from our prior guidance of $314 million to $316 million and compares to the $235.6 million for the full year of 2017. We now expect non-GAAP loss from operations to be in the range of $52.3 million to $51.3 million. Non-GAAP net loss to be in the range of $53 million to $52 million. And pro forma non-GAAP net loss per share in the range of $0.63 to $0.61, assuming weighted average shares outstanding of 84.8 million. And now, let me turn the call back to Amit for some closing comments.
