Accounting Policies [Abstract]	'
General	'
	NOTE 1:-	GENERAL
		a.	Varonis Systems, Inc. (“VSI” and together with its subsidiaries, collectively, the “Company”) was incorporated under the laws of the State of Delaware on November 3, 2004 and commenced operations on January 1, 2005.
	VSI has five wholly-owned subsidiaries: Varonis Systems Ltd. (“VSL”) incorporated under the laws of Israel on November 24, 2004; Varonis UK (“VSUK”) incorporated under the laws of England on March 14, 2007; Varonis Systems (Deutschland) GmbH (“VSG”) incorporated under the laws of Germany on July 6, 2011; Varonis France SAS (“VSF”) incorporated under the laws of France on February 22, 2012; and Varonis Systems Corp. (“VSC”) incorporated under the laws of British Columbia, Canada on February 19, 2013.
	The Company’s software products and services allow enterprises to map, analyze, manage and migrate their unstructured data. The Company specializes in human-generated data, a type of unstructured data that includes an enterprise’s word processing documents, spreadsheets, presentations, audio files, video files, emails, text messages, and any other data created by employees. Through its products the DatAdvantage platform, DataPrivilege, IDU Classification Framework, DatAnywhere, Data Transport Engine and DatAnswers (collectively, the “Products”), the software platform allows enterprises to realize the value of their human-generated data in ways that are not resource-intensive and easy to implement.
	VSI markets and sells products and services mainly in the United States. VSUK, VSG, VSF and VSC resell the Company’s products and services mainly in the UK, Germany, rest of Europe and Canada, respectively. The Company primarily sells its products and services to a global network of distributors and Value Added Resellers (VARs), which sell the products to end users customers.
	The Company had a stockholders’ equity (deficiency) of $93,146 (unaudited) and ($43,008) as of September 30, 2014 and December 31, 2013, respectively. The stockholders’ deficiency as of December 31, 2013 resulted from its preferred stock not being classified as equity. The preferred stock was only redeemable upon contingent events that were not probable. On March 5, 2014, the preferred stock was converted into common stock and therefore classified as equity (See Note 1b).
		b.	Initial Public Offering:
	On March 5, 2014, the Company closed its initial public offering (“IPO”) whereby 5,300,436 shares of common stock were sold by the Company to the public (inclusive of 500,436 shares of common stock pursuant to the full exercise of an overallotment option granted to the underwriters). The aggregate net proceeds received by the Company from the offering were approximately $106,071, net of underwriting discounts and commissions and offering expenses payable by the Company. Upon the closing of the IPO, all shares of the Company’s outstanding convertible preferred stock automatically converted into 15,082,141 shares of common stock, and outstanding warrants to purchase convertible preferred stock automatically converted into warrants to purchase 122,572 shares of common stock. On March 13, 2014, all such warrants were exercised, in a net share settlement, resulting in the issuance of 107,217 shares of common stock.
		c.	The significant accounting policies applied in the Company’s audited annual consolidated financial statements as of December 31, 2013 are applied consistently in these financial statements.
		d.	Basis of Presentation:
	The accompanying unaudited consolidated interim financial statements have been prepared in accordance with Article 10 of Regulation S-X, “Interim Financial Statements” and the rules and regulations for Form 10-Q of the Securities and Exchange Commission (the “SEC”). Pursuant to those rules and regulations, the Company has condensed or omitted certain information and footnote disclosure it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).
	In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its consolidated financial position, results of operations and cash flows. The Company’s interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the 2013 consolidated financial statements and notes thereto included in the prospectus filed with the SEC on March 3, 2014 (the “Prospectus”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”). There have been no changes in the significant accounting policies from those that were disclosed in the audited consolidated financial statements for the fiscal year ended December 31, 2013 included in the Prospectus.
		e.	Derivative Instruments:
	The Company’s primary objective for holding derivative instruments is to reduce its exposure to foreign currency rate changes. The Company reduces its exposure by entering into forward foreign exchange contracts with respect to operating expenses that are forecast to be incurred in currencies other than the U.S. dollar. A majority of the Company’s revenues and a majority of its operating expenditures are transacted in U.S. dollars. However, certain operating expenditures are incurred in or exposed to other currencies, primarily the New Israeli Shekel (“NIS”).
	The Company has established forecasted transaction currency risk management programs to protect against fluctuations in fair value and the volatility of future cash flows caused by changes in exchange rates. The Company’s currency risk management program includes forward foreign exchange contracts designated as cash flow hedges. These forward foreign exchange contracts generally mature within 12 months. The Company does not enter into derivative financial instruments for trading purposes.
	Derivative instruments measured at fair value and their classification on the consolidated balance sheets are presented in the following tables (in thousands):
			Liabilities as of
			September 30, 2014 (*)
			Notional		Fair
			Amount		Value
	Foreign Exchange Forward Contract Derivatives in cash flow hedging relationships - included in other current liabilities		$	8,079	$	(542	)
	(*)	The Company had no derivative instruments as of December 31, 2013.
	For the three and nine months ended September 30, 2014, the unaudited consolidated statements of operations reflect a loss of approximately $167 and $149, respectively, related to foreign currency forward contracts. The Company had no derivative instruments for the three and nine months ended September 30, 2013.
		f.	Recently Issued Accounting Pronouncement:
	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-08 (ASU 2014-08), “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company does not expect the impact of the adoption of ASU 2014-08 to be material to its consolidated financial statements
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”, an updated standard on revenue recognition. ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and US GAAP. The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (that is, payment) to which the company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. ASU 2014-09 will be effective for the Company in the first quarter of fiscal 2017 and may be applied on a full retrospective or modified retrospective approach. The Company is still evaluating the impact of implementation of this standard on its consolidated financial statements.

NOTE 2:-

FAIR VALUE MEASUREMENTS

The Company evaluates assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level to classify them for each reporting period. There have been no transfers between fair value measurements levels during the nine months ended September 30, 2014.

The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value:

•

Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

•

Level 2: Observable inputs that reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•

Level 3: Unobservable inputs reflecting our own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

The following table sets forth the Company’s assets and liabilities that were measured at fair value as of September 30, 2014 by level within the fair value hierarchy (in thousands):

	Summary information about geographic areas:
	ASC 280, “Segment Reporting,” establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company manages its business on the basis of one reportable segment and derives revenues from licensing of software, sale of professional services, maintenance and technical support (see Note 1 for a brief description of the Company’s business). The following is a summary of revenues within geographic areas:

Initial Public Offering	'
		b.	Initial Public Offering:
	On March 5, 2014, the Company closed its initial public offering (“IPO”) whereby 5,300,436 shares of common stock were sold by the Company to the public (inclusive of 500,436 shares of common stock pursuant to the full exercise of an overallotment option granted to the underwriters). The aggregate net proceeds received by the Company from the offering were approximately $106,071, net of underwriting discounts and commissions and offering expenses payable by the Company. Upon the closing of the IPO, all shares of the Company’s outstanding convertible preferred stock automatically converted into 15,082,141 shares of common stock, and outstanding warrants to purchase convertible preferred stock automatically converted into warrants to purchase 122,572 shares of common stock. On March 13, 2014, all such warrants were exercised, in a net share settlement, resulting in the issuance of 107,217 shares of common stock.
Basis of Presentation	'
		d.	Basis of Presentation:
	The accompanying unaudited consolidated interim financial statements have been prepared in accordance with Article 10 of Regulation S-X, “Interim Financial Statements” and the rules and regulations for Form 10-Q of the Securities and Exchange Commission (the “SEC”). Pursuant to those rules and regulations, the Company has condensed or omitted certain information and footnote disclosure it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).
	In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its consolidated financial position, results of operations and cash flows. The Company’s interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the 2013 consolidated financial statements and notes thereto included in the prospectus filed with the SEC on March 3, 2014 (the “Prospectus”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”). There have been no changes in the significant accounting policies from those that were disclosed in the audited consolidated financial statements for the fiscal year ended December 31, 2013 included in the Prospectus.
Derivative Instruments	'
		e.	Derivative Instruments:
	The Company’s primary objective for holding derivative instruments is to reduce its exposure to foreign currency rate changes. The Company reduces its exposure by entering into forward foreign exchange contracts with respect to operating expenses that are forecast to be incurred in currencies other than the U.S. dollar. A majority of the Company’s revenues and a majority of its operating expenditures are transacted in U.S. dollars. However, certain operating expenditures are incurred in or exposed to other currencies, primarily the New Israeli Shekel (“NIS”).
	The Company has established forecasted transaction currency risk management programs to protect against fluctuations in fair value and the volatility of future cash flows caused by changes in exchange rates. The Company’s currency risk management program includes forward foreign exchange contracts designated as cash flow hedges. These forward foreign exchange contracts generally mature within 12 months. The Company does not enter into derivative financial instruments for trading purposes.
	Derivative instruments measured at fair value and their classification on the consolidated balance sheets are presented in the following tables (in thousands):
			Liabilities as of
			September 30, 2014 (*)
			Notional		Fair
			Amount		Value
	Foreign Exchange Forward Contract Derivatives in cash flow hedging relationships - included in other current liabilities		$	8,079	$	(542	)
	(*)	The Company had no derivative instruments as of December 31, 2013.
	For the three and nine months ended September 30, 2014, the unaudited consolidated statements of operations reflect a loss of approximately $167 and $149, respectively, related to foreign currency forward contracts. The Company had no derivative instruments for the three and nine months ended September 30, 2013.
Recently Issued Accounting Pronouncement	'
		f.	Recently Issued Accounting Pronouncement:
	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-08 (ASU 2014-08), “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company does not expect the impact of the adoption of ASU 2014-08 to be material to its consolidated financial statements
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”, an updated standard on revenue recognition. ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and US GAAP. The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (that is, payment) to which the company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. ASU 2014-09 will be effective for the Company in the first quarter of fiscal 2017 and may be applied on a full retrospective or modified retrospective approach. The Company is still evaluating the impact of implementation of this standard on its consolidated financial statements.
