Organization Consolidation And Presentation Of Financial Statements [Abstract]
Business and Nature of Operations	(1) Business and Nature of Operations Everbridge, Inc., a Delaware corporation (together with its wholly-owned subsidiaries, referred to as “Everbridge” or the “Company”), is a global software company that provides critical communications and enterprise safety applications that enable customers to automate and accelerate the process of keeping people safe and businesses running during critical events. The Company’s SaaS-based platform enables the Company’s customers to quickly and reliably deliver messaging to a large group of people during critical situations. The Company’s enterprise applications automate numerous critical communications processes such as Mass Notification, Incident Management, IT Alerting, Safety Connection, Community Engagement, Secure Messaging and Internet of Things. The Company generates revenue primarily from subscription fees to the Company’s enterprise applications. The Company has operations in the United States, the United Kingdom and China.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. 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. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the final prospectus filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on September 16, 2016 (the “Prospectus”). The condensed consolidated balance sheet as of December 31, 2015, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2016 or any future period. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to judgment and use of estimates include allowances for doubtful accounts, the fair value of assets acquired and liabilities assumed in business combinations, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-based compensation. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engaged valuation specialists to assist with management’s determination of the valuation of its fair values of assets acquired and liabilities assumed in business combinations and, for all periods prior to the completion of the IPO, the valuation of the Company’s common stock. Concentrations of Credit and Business Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and accounts receivable. The Company maintains cash balances at several banks. Accounts located in the United States are insured by the Federal Deposit Insurance Corporation, or FDIC, up to $250,000. From time to time, balances may exceed amounts insured by the FDIC. The Company has not experienced any losses in such amounts. The Company’s accounts receivable are generally unsecured and are derived from revenue earned from customers located in the United States and the United Kingdom and are generally denominated in U.S. dollars or British pounds. Each reporting period, the Company reevaluates each customer’s ability to satisfy credit obligations and maintains an allowance for doubtful accounts based on the evaluations. No single customer comprised more than 10% of the Company’s total revenue or accounts receivable for the three months ended September 30, 2016 and 2015. No single customer comprised more than 10% of the Company’s total revenue or accounts receivable for the nine months ended September 30, 2016 and 2015. Significant Accounting Policies There have been no changes to our significant accounting policies described in the Prospectus. Recently Issued Accounting Guidance, Not Yet Adopted In August 2016, the Financial Accounting Standards Board ("FASB") issued new accounting guidance: Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice for certain cash receipts and cash payments. The amendments in this guidance are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and early adoption is permitted. The Company has elected not to early adopt. The Company is evaluating the impact of adopting this new accounting standard on its consolidated financial statements. In March 2016, the FASB Accounting Standards Updates (“ASU”) No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. This standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. The Company is evaluating the impact of this guidance on its condensed consolidated financial statements and related disclosures. In February, 2016, the FASB issued ASU No. 2016-02, “Leases”. The standard will affect all entities that lease assets and will require lessees to recognize a lease liability and a right-of-use asset for all leases (except for short-term leases that have a duration of less than one year) as of the date on which the lessor makes the underlying asset available to the lessee. For public companies, the new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. For leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, lessees and lessors must apply a modified retrospective transition approach. While the Company expects the adoption of this standard to result in an increase to the reported assets and liabilities, the Company has not yet determined the full impact that the adoption of this standard will have on its condensed consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”. This new guidance will replace most existing U.S. GAAP guidance on this topic. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14 which deferred, by one year, the effective date for the new revenue reporting standard for entities reporting under U.S. GAAP. In accordance with the deferral, this guidance will be effective for the Company beginning January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is permitted beginning January 1, 2017. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers, Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” clarifying the implementation guidance on principal versus agent considerations. Specifically, an entity is required to determine whether the nature of a promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). The determination influences the timing and amount of revenue recognition. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing”, clarifying the implementation guidance on identifying performance obligations and licensing. Specifically, the amendments reduce the cost and complexity of identifying promised goods or services and improve the guidance for determining whether promises are separately identifiable. The amendments also provide implementation guidance on determining whether an entity’s promise to grant a license provides a customer with either a right to use the entity’s intellectual property (which is satisfied at a point in time) or a right to access the entity’s intellectual property (which is satisfied over time). In May 2016, the FASB issued ASU 2016-12 “Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients”, which amends the guidance on transition, collectability, noncash consideration and the presentation of sales and other similar taxes. ASU 2016-12 clarifies that, for a contract to be considered completed at transition, all (or substantially all) of the revenue must have been recognized under legacy GAAP. In addition, ASU 2016-12 clarifies how an entity should evaluate the collectability threshold and when an entity can recognize nonrefundable consideration received as revenue if an arrangement does not meet the standard’s contract criteria. The effective date and transition requirements for ASU 2016-08, ASU 2016-10 and ASU 2016-12 are the same as the effective date and transition requirements for ASU 2014-09. The Company is evaluating the impact that these ASUs will have on its condensed consolidated financial statements and related disclosures and has not yet selected a transition method.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock Plans and Stock-Based Compensation

(9) Stock Plans and Stock-Based Compensation

The Company’s 2016 Equity Incentive Plan (the “2016 Plan”) became effective on September 15, 2016. The 2016 Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and performance share awards to employees, directors and consultants of the Company. A total of 3,893,118 shares of the Company’s common stock were initially reserved for issuance under the 2016 Plan, which is the sum of (1) 2,000,000 shares, (2) the number of shares reserved for issuance under the Company’s 2008 Equity Incentive Plan (the “2008 Plan”) at the time the 2016 Plan becomes effective (up to a maximum of 42,934 shares) and (3) shares subject to stock options or other stock awards granted under the 2008 Plan that would have otherwise returned to our 2008 Plan (up to a maximum of 1,850,184 shares). The number of shares of common stock reserved for issuance under the 2016 Plan will automatically increase on January 1 of each year, beginning on January 1, 2017, by 3% of the number of shares of the Company’s capital stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors.

As a result of the adoption of the 2016 Plan, no further grants may be made under the 2008 Plan. The 2008 Plan provided for the grant of stock options to the Company’s’ employees, directors and consultants. Stock option awards were granted with an exercise price equal to the fair market value of the Company’s common stock at the date of grant as determined by the Company’s board of directors. The option awards generally vested over four years and were exercisable any time after vesting. The stock options expire ten years after the date of grant.

2016 Employee Stock Purchase Plan

The Company’s Employee Stock Purchase Plan (“2016 ESPP”) became effective on September 15, 2016. A total of 500,000 shares of the Company’s common stock were initially reserved for issuance under the 2016 Plan. The number of shares reserved for issuance under the 2016 ESPP will automatically increase on January 1 of each year, beginning on January 1, 2017, by the lesser of 200,000 shares of the common stock, 1% of the number of shares of the Company’s common stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors.

The 2016 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15% through payroll deductions of their eligible compensation, subject to any plan limitations. Except for the initial offering period, the 2016 ESPP provides for separate six-month offering periods beginning each March and October of each fiscal year.

On each purchase date, eligible employees will purchase the Company’s stock at a price per share equal to 85% of the lesser of (i) the fair market value of the Company’s common stock on the offering date or (ii) the fair market value of the Company’s common stock on the purchase date.

For the three months ended September 30, 2016, no shares of common stock were purchased under the 2016 ESPP. The 2016 ESPP is considered compensatory for purposes of stock-based compensation expense.

Stock Options

The Company recorded stock-based compensation expense of $0.8 million and $2.2 million for the three and nine months ended September 30, 2016, respectively. The Company recorded stock-based compensation expense of $0.5 million and $0.9 million for the three and nine months ended September 30, 2015, respectively.

The total intrinsic value of options exercised for the three and nine months ended September 30, 2016 was $1.4 million and $2.0 million, respectively. This intrinsic value represents the difference between the fair market value of the Company’s common stock on the date of exercise and the exercise price of each option. Based on the fair market value of the Company’s common stock at September 30, 2016, the total intrinsic value of all outstanding options was $12.9 million.

The fair value of stock option grants is determined using the Black-Scholes option pricing model with the following weighted average assumptions. In addition, the fair value per share on grant date is presented below:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2016		2015		2016		2015
Employee Stock Options:
Fair value per share on grant date	$8.94 - $9.02		$5.06 - $7.76		$8.51 - $9.02		$5.06 - $7.76
Expected term (in years)	5.99 - 6.11		5.52 - 6.15		5.29 - 6.11		5.52 - 6.15
Expected volatility	70%		60%		70%		60%
Risk-free interest rate	1.21% - 1.25%		1.47% - 1.94%		1.21% - 1.86%		1.47% - 1.94%
Dividend rate		0%		0%		0%		0%

⁽¹⁾

The expected term represents the period that the stock-based compensation awards are expected to be outstanding. Since the Company did not have sufficient historical information to develop reasonable expectations about future exercise behavior, the Company used the simplified method to compute expected term, which reflects the average of the time-to-vesting and the contractual life;

⁽²⁾	The expected volatility of the Company’s common stock on the date of grant is based on the volatilities of publicly traded peer companies that are reasonably comparable to the Company’s own operations;

⁽³⁾	The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the options; and

⁽⁴⁾	The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on the Company’s common stock.

Total unrecognized compensation cost, adjusted for estimated forfeitures, related to nonvested stock options was approximately $6.7 million as of September 30, 2016, and is expected to be recognized over a weighted average period of 1.36 years.

A summary of activities under the 2008 Option Plan and the 2016 Option Plan is shown as follows for the years ended December 31, 2014 and 2015 and the nine months ended September 30, 2016:

	Stock options outstanding			Weighted average exercise price
Outstanding at December 31, 2014		699,662		$	2.24
Granted		1,190,317			12.19
Exercised		(37,559	)		1.32
Forfeited/canceled		(30,698	)		7.76
Outstanding at December 31, 2015		1,821,722			8.68
Granted		241,590			14.66
Exercised		(161,336	)		4.34
Forfeited/canceled		(55,123	)		8.29
Outstanding at September 30, 2016		1,846,853		$	9.89

Stock-based compensation expense is recognized over the award’s expected vesting schedule, which is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on the Company’s historical experience and future expectations.
