Revenue from Contract with Customer [Abstract]

We generate products revenue from the sale of (1) cloud-based subscriptions for our InsightIDR, InsightVM, InsightAppSec and InsightConnect products, (2) managed services offerings, which utilize our products and (3) term or perpetual software licenses for our Nexpose, Metasploit, and AppSpider products, and associated content subscriptions for our Nexpose and Metasploit products. We also generate appliance revenue that is included in our products revenue and is associated with hardware sold with our Nexpose product to certain customers. We generate maintenance and support revenue associated with customers’ purchases of our software licenses for Nexpose, Metasploit and AppSpider. We generate professional service revenue from the sale of our deployment and training services related to our solutions, incident response services and security advisory services. Our deployment services educate and assist our customers on the best use and best practices to deploy our solutions.

In accordance with FASB ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606), revenue is recognized when a customer obtains control of promised products or services. The amount of revenue recognized reflects the consideration that we expect to be entitled to receive in exchange for these products or services. To achieve the core principle of this standard, we apply the following five steps:

1) Identify the contract with a customer

We consider the terms and conditions of the contracts and our customary business practices in identifying our contracts under ASC 606. We determine we have a contract with a customer when the contract is approved, we can identify each party’s rights regarding the services to be transferred, we can identify the payment terms for the services, and we have determined the customer has the ability and intent to pay and the contract has commercial substance. We apply judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer.

2) Identify the performance obligations in the contract

Performance obligations promised in a contract are identified based on the products and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the products or services is separately identifiable from other promises in the contract.

3) Determine the transaction price

The transaction price is determined based on the consideration to which we expect to be entitled in exchange for transferring products or services to the customer. Variable consideration is included in the transaction price if, in our judgment, it is probable that no significant future reversal of cumulative revenue under the contract will occur.

In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to receive financing from our customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period.

4) Allocate the transaction price to performance obligations in the contract

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (SSP).

5) Recognize revenue when or as we satisfy a performance obligation

Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to a customer. Revenue is recognized when control of the products or services are transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those products or services.

Subscription Revenue

Subscription revenue consists of revenue from our cloud-based subscription, managed services offerings and content subscriptions associated with our software licenses.

•

We generate cloud-based subscription revenue primarily from sales of subscriptions to access our cloud platform, together with related support services to our customers. These arrangements do not provide the customer with the right to take possession of our software operating on our cloud platform at any time. Instead, customers are granted continuous access to our cloud platform over the contractual period. Revenue is recognized over time on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Our cloud-based subscription contracts generally have a term of one year, which is billed in advance and non-cancellable.


•	Managed services offerings consist of fees generated when we operate our software and provide our capabilities on behalf of our customers. Revenue is recognized on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Our managed services offerings generally have a term of one year, which is billed in advance and non-cancellable.


•	Revenue related to our content subscriptions associated with our software licenses is recognized ratably over the contractual period.


•	Some of our customers have the option to purchase additional subscription and support services at a stated price. These options generally do not provide a material right as they are priced at our SSP.

Certain subscription contracts contain service level commitments, which entitle our customers to receive service credits and, in certain cases, refunds, if our services do not meet certain levels. These service credits and refunds represent variable consideration. We have historically not experienced any significant incidents affecting the defined levels of reliability and performance as required by our subscription contracts and accordingly, no estimated refunds have been considered in the allocation of the transaction price.

Term and Perpetual Software Licenses

For our perpetual software licenses where the utility to the customer is dependent on the continued delivery of content subscriptions, the content subscription renewal options result in a material right with respect to the perpetual software license. As a result, the revenue attributable to the perpetual software license is recognized ratably over the customer’s estimated economic life of five years, which represents a longer period of time in comparison to the initial contractual period of maintenance and support. The estimated economic life of five years represents the period which the customer is expected to benefit from the material right. We estimated this period of benefit by taking into consideration several factors, including the terms and conditions of our customer contracts and renewals and the expected useful life of our technology.

For our term software licenses where the utility to the customer is dependent on the continued delivery of content subscriptions, we recognize the license revenue over the contractual term of the arrangement as a material right does not exist.

For our term and perpetual software licenses, which are not dependent on the continued delivery of content subscriptions, the license is considered distinct from the maintenance and support, and we therefore recognize revenue attributable to the license at the time of delivery.

Maintenance and Support

Maintenance and support services are sold with our perpetual and term software licenses. As maintenance and support services are distinct from the perpetual and term software license, revenue attributable to maintenance and support services is recognized ratably over the contractual period.

Professional Services

All of our professional services are considered distinct performance obligations when sold stand alone or with other products. These contracts generally have terms of one year or less. For the majority of these contracts, revenue is recognized over time based upon the proportion of work performed to date.

Other

Other revenue primarily includes revenue from delivery of appliances and other miscellaneous revenue.

Contracts with Multiple Performance Obligations

The majority of our contracts with customers contain multiple performance obligations. For these contracts, we account for individual performance obligations separately if they are considered distinct. The transaction price is allocated to the separate performance obligations on a relative SSP basis. We determine SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the geographic locations of our customers and selling method (i.e., partner or direct).

Contract Balances

Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are recognized as revenue over the contractual period consistent with the above methodology. For the three months ended June 30, 2019 and 2018, we recognized revenue of $66.6 million and $48.5 million, respectively, and for the six months ended June 30, 2019 and 2018, we recognized $117.2 million and $84.3 million, respectively, that was included in the corresponding

contract liability balance at the beginning of the periods presented. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining deferred revenue is recorded as non-current.

We receive payments from customers based upon contractual billing schedules. Accounts receivable are recorded when the right to consideration becomes unconditional. Contract assets, or unbilled receivables, include amounts related to our contractual right to consideration for both completed and partially completed performance obligations that may not have been invoiced. As of June 30, 2019 and December 31, 2018, contract assets of $0.5 million and $0.8 million, respectively, are included in prepaid expenses and other current assets in our consolidated balance sheet.

Deferred Contract Acquisition and Fulfillment Costs

We capitalize commission expenses paid to internal sales personnel and partner referral fees that are incremental costs to obtaining customer contracts. These costs are recorded as deferred contract acquisition costs in the consolidated balance sheets. Costs to obtain a contract for a new customer, up-sell or cross-sell are amortized on a straight-line basis over an estimated period of benefit of five years as sales commissions on initial sales are not commensurate with sales commissions on contract renewals. We determined the estimated period of benefit by taking into consideration the contractual term and expected renewals of customer contracts, our technology and other factors, including the fact that commissions paid on renewals are not commensurate with commissions paid on initial sales transactions. We periodically review the carrying amount of deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit. Commissions paid relating to contract renewals are deferred and amortized on a straight-line basis over the related renewal period. Costs to obtain a contract for professional services arrangements are expensed as incurred in accordance with the practical expedient as the contractual period of our professional services arrangements are one year or less.

Amortization expense associated with deferred contract acquisition costs is recorded to sales and marketing expense in our consolidated statements of operations.

We capitalize costs incurred to fulfill our contracts that relate directly to the contract, are expected to generate resources that will be used to satisfy our performance obligations and are expected to be recovered through revenue generated under the contract. Contract fulfillment costs are amortized on a straight-line basis over the estimated period of benefit and recorded as cost of products in our consolidated statement of operations.

The following table summarizes the activity of the deferred contract acquisition and fulfillment costs for the six months ended June 30, 2019 and 2018:



	Six Months Ended June 30,
	2019			2018
	(in thousands)
Beginning balance	$	39,955		$	27,165
Capitalization of contract acquisition and fulfillment costs	10,067			8,921
Amortization of deferred contract acquisition and fulfillment costs	(6,896		)	(4,391		)
Ending balance	$	43,126		$	31,695

Transaction price allocated to the remaining performance obligations

The following table includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied or partially unsatisfied as of June 30, 2019. The estimated revenues do not include unexercised contract renewals.



	Remainder of 2019		2020		2021 and thereafter
	(in thousands)
Subscription revenue	$	96,471	$	64,955	$	14,811
Term and perpetual software licenses	14,819		16,352		13,222
Maintenance and support	15,908		11,237		2,327

The amounts presented in the table above primarily consist of fixed fees, which are typically recognized ratably as the performance obligation is satisfied.

As of June 30, 2019, the estimated revenue expected to be recognized in the future related to professional services is $10.6 million. We will recognize this revenue as the professional services are completed, which is expected to occur within the next 12 months or less.
