October 23, 2016

Mr. Amit Yoran

Dear Amit:

On behalf of Tenable Network Security, Inc. (the “Company”), I am pleased to offer you employment in the position of Chief Executive Officer, reporting to the Board of Directors of Tenable Holdings, Inc. (“Holdings”), the Company’s parent (the “Board”). Upon acceptance of this offer, this letter sets forth our mutual agreement with respect to your employment with the Company (the “Letter Agreement”), which will start on a date mutually agreed to by you and the Company, but in no event later than January 1, 2017 (the “Commencement Date”).

1. Duties; Conduct During Employment. As Chief Executive Officer, you will have duties and responsibilities typically associated with such position, together with such other duties and responsibilities consistent with your position as reasonably assigned to you from time to time by the Board. For so long as you are the Chief Executive Officer of the Company, you will serve as a member of the Board, without additional compensation; provided, however, that you will have no rights to attend any meetings (or portions thereof) held in executive session or any meetings (or portions thereof) where the item of discussion relates to your employment, including (but not limited to) your compensation, performance, and or service on the Board; provided, further, that, after an initial public offering, the Board shall only be obligated to cause you to be nominated for election to the Board; and provided, further, that the foregoing shall not be required to the extent prohibited by legal or regulatory requirements and you are treated in the same manner as similarly situated directors. In connection with your employment with the Company, you agree to observe and comply with all of the rules, regulations, policies and procedures established by the Company from time to time and all applicable laws, rules and regulations imposed by any governmental regulatory authority from time to time. Without limiting the foregoing, you agree that during your employment with the Company, you will devote your full business time, attention, skill and best efforts to the performance of your employment duties and you are not to engage in any other business or occupation; provided, however, that (i) with the prior written notice to the Board, you may serve as a member of boards of directors (or its equivalent in the case of a non-corporate entity) of non-competing businesses, (ii) you may engage in volunteer activities, publish or fulfill speaking engagements, and (iii) manage your passive personal investments, so long as the activities set forth in clauses (i), (ii) and (iii) do not interfere, individually or in the aggregate, with the performance of your duties and responsibilities for the Company, are not competitive with the business of the Company, will not otherwise result in your breach of the Non-Disclosure Agreement (as defined below) or create a business or fiduciary conflict.

2. Compensation .

a. Base Salary. You will be paid a starting base salary of $400,000 per year, less applicable tax and other withholdings in accordance with the Company’s normal payroll procedure.

b. Incentive Compensation. You will be eligible to participate in the Company’s annual bonus program, with an annual target bonus equal to $200,000. The actual bonus earned by you will be based on achievement against targeted goals and objectives established by the Board and consistent with the Company’s business plan for that year (as approved by the Board after consultation with you). Your annual bonus is subject to normal payroll deductions and to the terms and conditions of the Company’s discretionary incentive compensation plan in force at that time. Notwithstanding the foregoing, for 2016, you will receive a pro-rata target bonus based on the number of days in such year that you actually worked as an employee of the Company. The payment of any annual bonus will be made at the same time annual bonuses are generally paid to other similarly situated employees of the Company, subject to your continued employment with the Company through the applicable payment date.

c. Equity Grants. We will request that the Board approve a grant for you of non-qualified stock options to purchase 2,839,524 shares of common stock of Holdings (the “Option’’) and 1,582,685 shares of restricted common stock or restricted common stock units, at your election, which together represent approximately 4.75% of the fully-diluted capitalization of Holdings (collectively, the “Equity Awards”). One-quarter (1/4) of each Equity Award will vest on the first anniversary of the Commencement Date, and the

remainder of each Equity Award will vest in equal quarterly installments for I he subsequent three (3) years, in each case subject to your continued employment with the Company on such date; provided that the Option will contain an “early exercise” provision that allows you to exercise the option as to vested and unvested shares, subject to a right of repurchase with respect to unvested shares at your original cost. The exercise price for the Option will be determined based on the fair market value of Holdings’ common stock on the date of grant. The Option shall be designated as an “incentive stock option” to the maximum extent possible.

As a member of the executive team, we will request that the Board grant your Equity Awards with double trigger change in control vesting acceleration. As such, pursuant to the terms of the Option Grant Notice and Agreement (the “Option Agreement”) and Restricted Stock/Restricted Stock Unit Grant Notice and Agreement (the “RS/RSU Agreement”) to be provided by Holdings, and in addition to any and all severance benefits set forth in this Letter Agreement, in the event your employment with the Company is terminated by the Company (other than for Cause (as defined in Exhibit A hereto) or on account of your death or permanent disability) or by you for Good Reason (as defined in Exhibit A hereto), at any time commencing on the date the Company enters into a definitive agreement providing for a Change in Control (as defined in Exhibit A hereto) and ending twelve (12) months following the closing of such Change in Control, then the then-unvested portion of the Equity Awards will accelerate and be deemed to be vested in full as of your termination date, subject to your execution of the Company’s standard form of release agreement not later than forty-five (45) days following your termination date (in which you release any and all known and unknown claims you may have against the Company and its affiliates). The Equity Awards will otherwise be subject to the terms and conditions specified in the Option Agreement, the RS/RSU Agreement and Holdings’ 2016 Stock Incentive Plan, each of which will be provided by Holdings.

3. Benefits. You will also be eligible for paid time off, group health, dental, 401 (k) and disability benefits, on the same basis as other similarly situated employees of the Company, commencing as of the first of the month following your Commencement Date. The Company expressly reserves the right to change the benefit plans and programs it offers to its employees at any time.

4. Termination. Subject to the terms of this Letter Agreement, the nature of your employment at the Company is and will continue to be “at will,” meaning that either the Company or you may terminate your employment at any time, with or without notice, with or without cause, and for any reason or for no reason. Any statement or representation to the contrary is ineffective unless put into a writing executed on behalf of the Company by the Board or its designee. We do ask, however, that you give thirty (30) days’ notice if you decide to terminate your employment. Upon any termination of your employment, no further payments by the Company to you will be due other than accrued but unpaid salary, unpaid and properly documented expense reimbursements and accrued vacation through the applicable date of your termination and any other accrued benefits (including, if applicable, the severance benefits outlined below) to which you may be entitled pursuant to the terms of benefit plans in which you participate at the time of such termination.

5. Severance Benefits. Although the Company expressly reserves the right to terminate your employment at any time and for any reason, should your employment with the Company be terminated by the Company other than for Cause, by you for Good Reason or on account of your death or permanent disability, you will be entitled to severance consisting of (i) continued payment of your base salary for a period of twelve (12) months in accordance with the Company’s normal payroll procedure and (ii) should you timely elect to continue healthcare coverage through COBRA, twelve (12) months reimbursement of the amount by which your COBRA premium exceeds the premium paid by the Company’s active employees for similar coverage, payable monthly. The foregoing severance is conditioned upon your compliance with your continuing obligations to the Company (as detailed in the attached Intellectual Property, Non-Disclosure, and Non-Solicitation Agreement (the “Non-Disclosure Agreement”)), your resignation or termination from all positions you then hold with Holdings, the Company and any of their subsidiaries, and your execution of the Company’s standard form of release agreement not later than forty-five (45) days following your termination date (in which you release any and all known and unknown claims you may have against the Company and Its affiliates). Further, to the extent that any of the severance benefits constitutes “nonqualified deferred compensation” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), any payment of any amount or provision of any benefit otherwise scheduled to occur prior to the sixtieth (6^th) day following the date your termination of employment hereunder, but for the condition on executing the form of release as set forth herein, shall not be made until the first regularly scheduled payroll date following such sixtieth (60^th) day. In addition, the payment (or commencement of a series of payments) hereunder of any such “nonqualified deferred compensation” (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as you have also undergone a “separation from service” as defined in Treas. Reg. 1.409A-1 (h), at which time such nonqualified deferred compensation (calculated as of the date of your termination of employment hereunder) shall be paid (or commence to be paid) to you on the schedule set forth herein as if you had undergone such termination of employment (under the same circumstances) on the date of your ultimate “separation from service.” Each installment described in this section (and all other payments to be made in installments as a result of this Letter Agreement) shall be deemed to be a separate payment for purposes of Section 409A of the Code.

6. Golden Parachute Considerations. If any payment or benefit due under this Letter Agreement, together with all other payments and benefits that you receive or are entitled to receive from the Company or any of its subsidiaries, affiliates or related entities, would (if paid or provided) constitute an excess parachute payment for purposes of Section 280G of the Code, the amounts otherwise payable and benefits otherwise due under this Letter Agreement will either (I) be delivered in full, or (ii) be limited to the minimum extent necessary to ensure that no portion thereof will fail to be tax-deductible to the Company by reason of Section 280G of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state or local income and employment taxes and the excise tax imposed under Section 4999 of the Code, results in your receipt, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be subject to the excise tax imposed under Section 4999 of the Code. If the payments and/or benefits are to be reduced pursuant to this section, such payments and benefits shall be reduced such that the reduction of cash compensation to be provided to you as a result of this section is minimized. In applying this principle, the reduction shall be made in a manner consistent with the requirements of Section 409A of the Code and where two economically equivalent amounts are subject to reduction but payable at different times, such amounts shall be reduced on a pro rata basis but not below zero. Notwithstanding the foregoing, if it appears that any payment or benefit due under this Letter Agreement, together with all other payments and benefits that you receive or are entitled to receive from the Company or any of its subsidiaries, affiliates or related entities that is to be paid to you under this Letter Agreement or any other plan, program, agreement, or arrangement of the Company or any of its affiliates may constitute a “parachute payment” under section 280G(b)(2) of the Code, the Company shall use its reasonable best efforts to obtain shareholder approval of such payments in a manner intended to comply with Section 280G(b)(5) of the Code.

7. Non-Disclosure Agreement; Evidence of Employment Eligibility. As a condition of your employment with the Company, you will be required to sign, and comply with, the attached Non-Disclosure Agreement, and to provide the Company with documents establishing your identity and right to work in the United States. Those documents must be provided to the Company within three business days of your Commencement Date.

8. Background Checks. The Company reserves the right to conduct a background Investigation and/or reference check on all of its potential employees. Your offer of employment is contingent upon satisfactory completion of such background investigation and/or reference check, If any, In the sole discretion of the Company. All such background Investigations and/or reference checks shall be conducted In accordance with applicable state and federal laws.

9. Entire Agreement. This Letter Agreement, the Non-Disclosure Agreement, the Option Agreement and the RS/RSU

Agreement constitute the entire agreement between you and the Company regarding the terms and conditions of your employment, and they supersede all prior or contemporaneous negotiations, representations or agreements between you and the Company.

10. Former Employer Information.

By signing this Letter Agreement, you represent and warrant to the Company that you are under no contractual commitments Inconsistent with your obligations to the Company hereunder and that your acceptance of this offer of employment and your performance of the contemplated services hereunder does not and will not conflict with or result In any breach or default under any agreement, contract or arrangement to which you are a party to or violate any other legal restriction.
