Description of Business and Basis of Presentation and Consolidation Description of Business Rapid7, Inc. and subsidiaries is a leading provider of security data and analytics solutions that enable organizations to implement an active, analytics-driven approach to cyber security. Our solutions empower organizations to prevent attacks by providing visibility into vulnerabilities and to rapidly detect compromises, respond to breaches and correct the underlying causes of attacks. Basis of Presentation and Consolidation The accompanying unaudited consolidated financial statements have been prepared by us in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) as well as pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our final prospectus for our initial public offering (IPO) dated as of July 16, 2015 and filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended. The consolidated financial statements include our results of operations and those of our wholly-owned subsidiaries and reflect all adjustments (consisting solely of normal, recurring adjustments) which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results to be expected for any future period or the entire fiscal year.

Equity [Abstract]
Initial Public Offering	Note 2. Initial Public Offering On July 22, 2015, we closed our IPO of 7,417,500 shares of common stock at an offering price of $16.00 per share, including 967,500 shares pursuant to the underwriters’ option to purchase additional shares, resulting in net proceeds of $107.3 million, after deducting underwriting discounts and commissions of $8.3 million and offering expenses of $3.1 million. Upon the closing of the IPO, all of our outstanding preferred stock automatically converted into 18,322,605 shares of common stock, which included 1,939,990 additional shares of common stock issued upon conversion of our Series D preferred stock (IPO Participation Payment). As a result of the completion of the IPO and the IPO Participation Payment, we recorded a $14.2 million beneficial conversion charge during the three month period ended September 30, 2015. The amount of the beneficial conversion charge was calculated by multiplying the total number of shares of common stock issued upon the conversion of our Series D preferred stock, including the additional shares of common stock issued in connection with the IPO Participation Payment, by the difference between the fair market value of our common stock at the time of the original issuance of the Series D preferred stock and the effective conversion price of the Series D preferred stock, which is calculated as the aggregate proceeds from the sale of Series D preferred stock, divided by the total number of shares of common stock issued upon conversion of our Series D preferred stock, including the additional shares of common stock issued in connection with the IPO Participation Payment. On July 22, 2015, concurrently with the closing of our IPO, we issued and sold to entities affiliated with Technology Crossover Ventures 312,500 shares of our common stock in a private placement at a price equal to the IPO price of $16.00 per share, resulting in net proceeds to us of $5.0 million. Additionally, in connection with the closing of our IPO, we filed an amended and restated certificate of incorporation to, among other things (i) increase the total number of shares of our common stock that we are authorized to issue to 100,000,000 and (ii) eliminate all references to the various series of preferred stock that were previously authorized (including certain protective measures held by the various series of preferred stock), except for the reference to 10,000,000 shares of undesignated preferred stock that may be issued, and with terms to be set, by our board of directors.

Business Combinations [Abstract]
Business Combinations	Note 3. Business Combinations On April 30, 2015, we acquired 100% of the outstanding equity of NT OBJECTives, Inc. (NTO), a web application security testing company, expanding the web application testing capabilities of our Threat Exposure Management offering. We acquired NTO for total consideration of $6.1 million. We made an initial payment of $3.4 million in cash and issued $0.1 million (9,091 shares) of our common stock upon the closing of the acquisition, are obligated to pay $0.1 million in cash for the settlement of a working capital adjustment and are obligated to make two additional payments of $1.5 million each, less the amount of any indemnity claims, on the first and second anniversary dates of the closing. The net present value of these two additional payments, or $2.5 million, is included in the total purchase consideration paid. We expensed the related acquisition costs of $0.4 million in general and administrative expense. The following table summarizes the consideration paid for NTO and the preliminary allocation of purchase price to the estimated fair value of the assets acquired and liabilities assumed at the acquisition date: Consideration (in thousands): Cash $ 3,404 Stock consideration 99 Net working capital liability 48 Net present value of deferred cash payments 2,535 Fair value of total consideration transferred $ 6,086 Recognized amounts of identifiable assets acquired and liabilities assumed (in thousands): Net working capital $ (586 ) Intangible assets 2,090 Total identifiable net assets assumed 1,504 Goodwill 4,582 Net purchase price $ 6,086 The fair values of identifiable intangible assets were based on valuations using the income approach. The estimated fair values and useful lives of the identifiable intangible assets are as follows: Amount Weighted-average life (in thousands) (years) Developed technology $ 1,950 6 Customer relationships 100 4 Non-compete agreements 40 2 Identifiable intangible assets $ 2,090 The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. We believe the amount of goodwill is the expected synergistic benefits of being able to leverage the integration of our existing products and services with the acquired products to both NTO and our customer bases. The goodwill was allocated to our one reportable segment. The acquired goodwill and intangible assets will not be deductible for tax purposes. These preliminary amounts are subject to subsequent adjustment as we obtain additional information to finalize certain components of working capital. Pro forma results of operations have not been included, as the acquisition of NTO was not material to our results of operations for any periods presented. In May 2015, we entered into loan agreements with certain retained employees of NTO. The terms of these agreements require the employees to pay us the total amount borrowed, with accrued interest at 1.7% per annum, within 18 months of the agreement date. The loan agreements are secured by restricted stock awards granted to the employees. The aggregate amount of these loans was $0.5 million and is classified as other assets on the consolidated balance sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9. Commitments and Contingencies (a) Warranty We provide limited product warranties. Historically, any payments made under these provisions have been immaterial. (b) Litigation and Claims From time to time, in the normal course of business, various claims are made by customers or other third parties against us, or such claims may be pending or threatened. When we believe that an adverse outcome from such a claim is both probable and estimable, a reserve for the estimated liability is recorded. We do not expect any liabilities from claims to have a material adverse effect on our financial position or results of operations. (c) Indemnification Obligations We agree to standard indemnification provisions in the ordinary course of business. Pursuant to these provisions, we agree to indemnify, hold harmless and reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally our customers, in connection with any United States patent, copyright or other intellectual property infringement claim by any third party arising from the use of our products or services in accordance with the agreement or arising from our gross negligence, willful misconduct or violation of the law (provided that there is not gross or willful misconduct on the part of the other party) with respect to our products or services. The term of these indemnification provisions is generally perpetual from the time of execution of the agreement. We carry insurance that covers certain third-party claims relating to our services and limits our exposure. We have never incurred costs to defend lawsuits or settle claims related to these indemnification provisions. (d) Leases On August 17, 2015, we entered into an amendment to our lease agreement for our principal executive offices in Boston, Massachusetts for approximately 20,000 additional square feet. We expect to occupy the additional office space in 2016 and the term of the lease is 42 months.
