Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognized an income tax expense of $50.1 million and $1.0 million for the three months ended April 30, 2021 and April 30, 2020, respectively. The tax expense for the three months ended April 30, 2021 was primarily attributable to the intercompany sale of intellectual property and pre-tax foreign earnings. The Company’s effective tax rates of (143.1)% and (5.7)% for the three months ended April 30, 2021 and April 30, 2020, respectively, differ from the U.S. statutory tax rate primarily due to U.S. losses for which there is no benefit and the tax impact from the intercompany sale of intellectual property from Humio. The Company has a full valuation allowance on its U.S. federal and state and its U.K. deferred tax assets. As a result, consistent with the prior year, the Company does not record a tax benefit on these losses because it is more likely than not that the benefit will not be realized. The balance of gross unrecognized tax benefits was $51.1 million and $24.4 million as of April 30, 2021 and January 31, 2021, respectively. The increase was primarily due to establishing an uncertain tax position associated with the intercompany sale of intellectual property. As of April 30, 2021 and January 31, 2021, approximately $23.0 million and $0.6 million, respectively of the unrecognized tax benefits including interest and penalties would affect the Company’s effective tax rate if favorably resolved. Given the uncertainty of the timing of resolving the issue, the Company is unable to estimate the range of possible changes to the balance of our unrecognized tax benefits within the next 12 months. In accordance with the guidance on the accounting for uncertainty in income taxes, for all U.S. and other tax jurisdictions, the Company recognize potential liabilities for anticipated tax audit issues based on the Company’s estimate of whether, and the extent to which, additional taxes and interest will be due. If the Company’s estimate of income tax liabilities proves to be less than the ultimate assessment, a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. The Company include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the condensed consolidated statements of operations. Accrued interest and penalties are included within other liabilities, noncurrent in the condensed consolidated balance sheet.
