Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Contingencies — From time to time, the Company is involved in claims and legal proceedings that arise in the ordinary course of business. SecureWorks accrues a liability when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of the loss. The Company reviews the status of legal cases at least quarterly and adjusts its liabilities as necessary to reflect ongoing negotiations, settlements, rulings, advice of legal counsel and other relevant information. Whether the outcome of any claim, suit, assessment, investigation or legal proceeding, individually or collectively, could have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows will depend on a number of factors, including the nature, timing and amount of any associated expenses, amounts paid in settlement, damages or other remedies or consequences. To the extent new information is obtained and the Company’s views on the probable outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in accrued liabilities would be recorded in the period in which such determination is made. As of October 28, 2016, the Company does not believe there are any matters, individually or in the aggregate, that could have a material adverse effect on its results of operations, financial condition or liquidity. During the fiscal year ended January 29, 2016, there was one legal matter settled, which is summarized below: SRI International v. Dell Inc. and SecureWorks, Inc. — On April 26, 2013, SRI International filed a complaint in the United States District Court for the District of Delaware against the Company and Dell Inc. captioned “SRI International, Inc. v. Dell Inc. and SecureWorks, Inc., Civ. No. 13-737-SLR.” The complaint alleged that the Company and Dell Inc. were infringing and inducing the infringement of SRI International patent U.S. 6,711,615 covering network intrusion detection technology and SRI International patent U.S. 6,484,203 covering hierarchical event monitoring analysis. SRI International sought damages (including enhanced damages for alleged willful infringement), a recovery of costs and attorneys’ fees, and other relief as the court deemed appropriate, and demanded a jury trial. The Company filed an answer to SRI International’s complaint which asserted affirmative defenses and counterclaims, including that the Company does not infringe or induce the infringement of the asserted patents and that the asserted patents are invalid and unenforceable. In July 2015, the Company undertook settlement discussions with SRI International. In August 2015, SRI International and Dell Inc. entered into a settlement and license agreement under which SRI International granted to Dell Inc. and its affiliates a perpetual, fully paid-up, non-transferable, non-assignable or sublicensable worldwide license under the patents subject to the litigation. Dell Inc. paid to SRI International a one-time lump sum of $7.5 million and the parties agreed to stipulate to dismissal with prejudice of all claims asserted by SRI International and dismissal without prejudice of all claims asserted by Dell Inc. or the Company in the litigation. Under the settlement and license agreement, if any affiliate of Dell Inc. (including the Company) ceases to be an affiliate of Dell Inc., that entity will retain its license under the agreement with SRI International, subject to certain terms and conditions as set out in the agreement with SRI International. The United States District Court for the District of Delaware dismissed the action in September 2015. In connection with this matter, the Company expensed $3.0 million and $1.9 million in the first and second quarters, respectively, of fiscal 2016. In addition, the Company recognized a $2.6 million prepaid patent license agreement during the second quarter of fiscal 2016. Indemnifications — In the ordinary course of business, SecureWorks enters into contractual arrangements under which the Company agrees to indemnify its clients from certain losses incurred by the client as to third-party claims relating to the services performed on behalf of SecureWorks or for certain losses incurred by the client as to third-party claims arising from certain events as defined within the particular contract. Such indemnification obligations may not be subject to maximum loss clauses. Historically, payments related to these indemnifications have been immaterial. Concentrations — The Company sells solutions to clients of all sizes primarily through its direct sales organization, supplemented by sales through channel partners. The Company had a single client that represented approximately 8% of its revenue for both the three and nine months ended October 28, 2016 and 8% and 9% for the three and nine months ended October 30, 2015, respectively.
