Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Business and Basis of Presentation	DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION Description of the Business SecureWorks Corp. (individually and collectively with its consolidated subsidiaries, “SecureWorks” or the “Company”) is a leading global provider of intelligence-driven information security solutions singularly focused on protecting the Company's clients from cyber attacks. The Company's solutions enable organizations of varying size and complexity to fortify their cyber defenses to prevent security breaches, detect malicious activity in near real time, prioritize and respond rapidly to security incidents and predict emerging threats. The Company has one primary business activity, which is to provide clients with intelligence-driven information security solutions. The Company’s chief operating decision maker, who is the President and Chief Executive Officer, makes operating decisions, assesses performance, and allocates resources on a consolidated basis. Accordingly, SecureWorks operates its business as a single reportable segment. On February 8, 2011, the Company was acquired by Dell Inc. (individually and collectively with its consolidated subsidiaries, “Dell” or “Parent”). On October 29, 2013, Dell was acquired by Dell Technologies Inc., formerly known as Denali Holding Inc. (“Dell Technologies”), a parent holding corporation. For the purposes of the accompanying financial statements, the Company elected to utilize pushdown accounting for the acquisition of Dell by Dell Technologies. On April 27, 2016, the Company completed its initial public offering ("IPO"), as further described below. Upon the closing of the IPO, Dell Technologies owned, indirectly through Dell Inc. and Dell Inc.’s subsidiaries, no shares of the Company's outstanding Class A common stock and all shares of the Company's outstanding Class B common stock, which as of February 3, 2017 represented approximately 86.9% of the Company's total outstanding shares of common stock and approximately 98.5% of the combined voting power of both classes of the Company's outstanding common stock. The predecessor company of SecureWorks was originally formed as a limited liability company in Georgia in March 1999, and SecureWorks was incorporated in Georgia in May 2009. On November 24, 2015, the Company reincorporated from Georgia to Delaware and, in connection with the reincorporation, changed its name from SecureWorks Holding Corporation to SecureWorks Corp. and its authorized capital from 1,000 shares of common stock, par value $0.01 per share, to 1,000 shares of Class A common stock and 1,000 shares of Class B common stock, each with a par value of $0.01 per share. There are no differences in dividend and liquidation rights between the Class A common stock and the Class B common stock. Each share of Class A common stock is entitled to one vote and each share of Class B common stock is entitled to ten votes. Upon the reincorporation, the 1,000 issued and outstanding shares of common stock of the Georgia corporation were reclassified into and became 1,000 issued and outstanding shares of Class B common stock of SecureWorks Corp., the Delaware corporation. In January 2016, the Company’s board of directors and stockholder approved a 70,000-for-1 stock split of the Company’s Class B common stock. The Company filed an amendment to its certificate of incorporation effecting the stock split on April 8, 2016. The amendment to the certificate of incorporation also increased the number of shares of Class A common stock authorized for issuance from 1,000 to 2,500,000,000 shares and increased the number of shares of Class B common stock authorized for issuance from 1,000 to 500,000,000 shares. All share and per share amounts presented in these financial statements have been retroactively adjusted to reflect the impact of the stock split. In April 2016, the Company’s board of directors and stockholder approved a restated certificate of incorporation further amending and restating the provisions of the certificate of incorporation. The restated certificate of incorporation, which was filed on April 22, 2016, authorized for issuance 200,000,000 shares of preferred stock, par value $0.01 per share. In connection with the IPO, the Company created certain new foreign legal entities that became consolidated subsidiaries of SecureWorks Corp. After their formation and generally effective on August 1, 2015, the carve-out date, the new subsidiaries of SecureWorks Corp. received transfers of net assets from other Dell legal entities of businesses that have been included in the historical combined financial statements of the Company. The net assets were transferred by Dell for no consideration, at their carrying values, which represented Dell’s historical costs and which constitute the basis reflected in these historical combined financial statements. Because these businesses already have been included in the historical combined financial statements for all periods, the sole impact of the transfers was the completion of the legal reorganization of entities under common control and the presentation of the resulting change in the reporting entity under Accounting Standards Codification (“ASC”) 805 – Business Combinations. Because SecureWorks Corp. legally owned all of the businesses reflected in the previously presented combined financial statements as of January 29, 2016, the presentation as of such date is of a consolidated business, with the only effect being the reclassification of the previously reported balances in net parent investment as common stock, additional paid in capital and accumulated deficit of SecureWorks Corp. Initial Public Offering On April 27, 2016, the Company completed its IPO in which it issued and sold 8,000,000 shares of Class A common stock at a price to the public of $14.00 per share. The Company received net proceeds of $99.6 million from the sale of shares of Class A common stock, after deducting underwriting discounts and commissions and unpaid offering expenses payable by the Company of $12.4 million. Upon the closing of the IPO, all of the Company's convertible notes automatically converted into 2,008,924 shares of the Class A common stock. For more information regarding the convertible notes see "Note 5—Debt." Basis of Presentation and Consolidation The Company’s consolidated financial statements have been prepared on a stand-alone basis in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and, for periods prior to the carve-out date, were derived from the accounting records of Dell and the Company, whereby certain transactions are outside SecureWorks Corp. Beginning in the third quarter of fiscal 2016, the costs of these services were charged in accordance with a shared services agreement between the Company and Dell that went into effect on August 1, 2015. The Company’s results of operations, particularly prior to the carve-out date, are not necessarily indicative of its future performance and do not reflect what the Company’s financial performance would have been had it been a stand-alone public company during all periods presented. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s financial statements. The consolidated financial statements include assets, liabilities, revenue and expenses of all majority-owned subsidiaries. Intercompany transactions and balances are eliminated in consolidation. Assets and liabilities that are specifically identifiable or otherwise attributable to the Company, such as intangible assets, are included in the Consolidated Statements of Financial Position. Debt held by Dell, and related interest expense have not been allocated to SecureWorks for any of the periods presented as these borrowings were not directly attributable to the Company’s operations. Cash transfers between the Company and Dell prior to August 1, 2015 have been included in these financial statements as a component of permanent equity, as such amounts do not require repayment. The total net effect of these transfers is reflected in the Consolidated Statements of Financial Position and the Consolidated Statements of Stockholders' Equity as transfers from Parent and in the Consolidated Statements of Cash Flows as a financing activity. For the periods presented, Dell has provided various corporate services to the Company in the ordinary course of business, including finance, tax, human resources, legal, insurance, IT, procurement and facilities-related services. Dell also has provided the Company with the services of a number of its executives and employees. Through the first two quarters of fiscal 2016, the costs of such services were allocated to the Company based on the most relevant allocation method to the service provided, primarily based on relative percentage of total net sales, relative percentage of headcount, or specific identification. Management believes the basis on which the expenses have been allocated to be a reasonable reflection of the utilization of services provided to or the benefit received by the Company during the periods presented. As discussed above, beginning in the third quarter of fiscal 2016, the costs of these services were charged in accordance with the shared services agreement that went into effect on August 1, 2015. For more information regarding the allocated costs and related party transactions, see “Note 10-Related Party Transactions.” During the periods presented in the financial statements, SecureWorks did not file separate federal tax returns, as the Company was generally included in the tax grouping of other Dell entities within the respective entity’s tax jurisdiction. The income tax benefit has been calculated using the separate return method, modified to apply the benefits for loss approach. Under the benefits for loss approach, net operating losses or other tax attributes are characterized as realized or as realizable by SecureWorks when those attributes are utilized or expected to be utilized by other members of the Dell consolidated group. See “Note 8—Income and Other Taxes” for more information. Fiscal Year The Company’s fiscal year is the 52- or 53-week period ending on the Friday closest to January 31. The Company refers to the fiscal years ending February 3, 2017, January 29, 2016, and January 30, 2015 as fiscal 2017, fiscal 2016, and fiscal 2015, respectively. Fiscal 2017 included 53 weeks, with the extra week included in the fourth quarter, and fiscal 2016 and fiscal 2015 included 52 weeks. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Estimates are revised as additional information becomes available. In the Consolidated Statements of Operations, estimates are used when accounting for revenue arrangements, determining cost of revenue, allocating cost in the form of depreciation and amortization and estimating the impact of contingencies. In the Statements of Financial Position, estimates are used in determining the valuation and recoverability of assets, such as accounts receivables, inventories, fixed assets, goodwill and other identifiable intangible assets, and estimates are used in determining the reported amounts of liabilities, such as taxes payable and the impact of contingencies, all of which also impact the Consolidated Statements of Operations. Actual results could differ from these estimates. Out-of-Period Adjustments The financial statements presented for the fiscal year ended January 29, 2016 include adjustments to correct errors related to the fiscal year ended January 30, 2015. For the fiscal year ended January 29,2016, the out-of-period adjustments increased loss before taxes and net loss by approximately $3.7 million and $2.4 million, respectively. The out-of-period adjustments primarily relate to the timing of services revenue, recognition, cost of sales of hardware equipment sold but not expensed, and compensation expense from fiscal 2015 not recorded. Because management concluded these errors, both individually and in the aggregate, were not material to any of the prior periods’ financial statements, and because the impact of correcting these errors in fiscal 2016 was not material to the financial statements presented, the Company recorded the correction of these errors in its fiscal 2016 financial statements presented in its registration statement on Form S-1 filed in connection with the IPO. Reclassification Certain amounts in prior fiscal years have been reclassified to conform with the presentation in the current fiscal year. See "Note 2—Significant Accounting Policies."

Initial Public Offering

On April 27, 2016, the Company completed its IPO in which it issued and sold 8,000,000 shares of Class A common stock at a price to the public of $14.00 per share. The Company received net proceeds of $99.6 million from the sale of shares of Class A common stock, after deducting underwriting discounts and commissions and unpaid offering expenses payable by the Company of $12.4 million.

Upon the closing of the IPO, all of the Company's convertible notes automatically converted into 2,008,924 shares of the Class A common stock. For more information regarding the convertible notes see "Note 5—Debt."

Basis of Presentation and Consolidation

The Company’s consolidated financial statements have been prepared on a stand-alone basis in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and, for periods prior to the carve-out date, were derived from the accounting records of Dell and the Company, whereby certain transactions are outside SecureWorks Corp. Beginning in the third quarter of fiscal 2016, the costs of these services were charged in accordance with a shared services agreement between the Company and Dell that went into effect on August 1, 2015. The Company’s results of operations, particularly prior to the carve-out date, are not necessarily indicative of its future performance and do not reflect what the Company’s financial performance would have been had it been a stand-alone public company during all periods presented. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s financial statements. The consolidated financial statements include assets, liabilities, revenue and expenses of all majority-owned subsidiaries. Intercompany transactions and balances are eliminated in consolidation.

Assets and liabilities that are specifically identifiable or otherwise attributable to the Company, such as intangible assets, are included in the Consolidated Statements of Financial Position. Debt held by Dell, and related interest expense have not been allocated to SecureWorks for any of the periods presented as these borrowings were not directly attributable to the Company’s operations. Cash transfers between the Company and Dell prior to August 1, 2015 have been included in these financial statements as a component of permanent equity, as such amounts do not require repayment. The total net effect of these transfers is reflected in the Consolidated Statements of Financial Position and the Consolidated Statements of Stockholders' Equity as transfers from Parent and in the Consolidated Statements of Cash Flows as a financing activity.

For the periods presented, Dell has provided various corporate services to the Company in the ordinary course of business, including finance, tax, human resources, legal, insurance, IT, procurement and facilities-related services. Dell also has provided the Company with the services of a number of its executives and employees. Through the first two quarters of fiscal 2016, the costs of such services were allocated to the Company based on the most relevant allocation method to the service provided, primarily based on relative percentage of total net sales, relative percentage of headcount, or specific identification. Management believes the basis on which the expenses have been allocated to be a reasonable reflection of the utilization of services provided to or the benefit received by the Company during the periods presented. As discussed above, beginning in the third quarter of fiscal 2016, the costs of these services were charged in accordance with the shared services agreement that went into effect on August 1, 2015. For more information regarding the allocated costs and related party transactions, see “Note 10-Related Party Transactions.”

During the periods presented in the financial statements, SecureWorks did not file separate federal tax returns, as the Company was generally included in the tax grouping of other Dell entities within the respective entity’s tax jurisdiction. The income tax benefit has been calculated using the separate return method, modified to apply the benefits for loss approach. Under the benefits for loss approach, net operating losses or other tax attributes are characterized as realized or as realizable by SecureWorks when those attributes are utilized or expected to be utilized by other members of the Dell consolidated group. See “Note 8—Income and Other Taxes” for more information.

Fiscal Year

The Company’s fiscal year is the 52- or 53-week period ending on the Friday closest to January 31. The Company refers to the fiscal years ending February 3, 2017, January 29, 2016, and January 30, 2015 as fiscal 2017, fiscal 2016, and fiscal 2015, respectively. Fiscal 2017 included 53 weeks, with the extra week included in the fourth quarter, and fiscal 2016 and fiscal 2015 included 52 weeks.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Estimates are revised as additional information becomes available. In the Consolidated Statements of Operations, estimates are used when accounting for revenue arrangements, determining cost of revenue, allocating cost in the form of depreciation and amortization and estimating the impact of contingencies. In the Statements of Financial Position, estimates are used in determining the valuation and recoverability of assets, such as accounts receivables, inventories, fixed assets, goodwill and other identifiable intangible assets, and estimates are used in determining the reported amounts of liabilities, such as taxes payable and the impact of contingencies, all of which also impact the Consolidated Statements of Operations. Actual results could differ from these estimates.

Out-of-Period Adjustments

The financial statements presented for the fiscal year ended January 29, 2016 include adjustments to correct errors related to the fiscal year ended January 30, 2015. For the fiscal year ended January 29,2016, the out-of-period adjustments increased loss before taxes and net loss by approximately $3.7 million and $2.4 million, respectively. The out-of-period adjustments primarily relate to the timing of services revenue, recognition, cost of sales of hardware equipment sold but not expensed, and compensation expense from fiscal 2015 not recorded. Because management concluded these errors, both individually and in the aggregate, were not material to any of the prior periods’ financial statements, and because the impact of correcting these errors in fiscal 2016 was not material to the financial statements presented, the Company recorded the correction of these errors in its fiscal 2016 financial statements presented in its registration statement on Form S-1 filed in connection with the IPO.

Reclassification

Certain amounts in prior fiscal years have been reclassified to conform with the presentation in the current fiscal year. See "Note 2—Significant Accounting Policies."
