(ii) to pay or discharge any Liens, including, without limitation, any tax lien, levied or placed on or threatened against the Collateral, to effect any repairs or any insurance called for by the terms of this Security Agreement and to pay all or any part of the premiums therefor and the costs thereof, which actions shall be for the benefit of the Secured Parties and not Grantor;

(iii) to (1) direct any person liable for any payment under or in respect of any of the Collateral to make payment of any and all monies due or to become due thereunder directly to the Secured Parties or as the Secured Parties shall direct, (2) receive payment of any and all monies, claims and other amounts due or to become due at any time arising out of or in respect of any Collateral, (3) sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications and notices in connection with Accounts and other Instruments and Documents constituting or relating to the Collateral, (4) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other right in respect of any Collateral, (5) defend any suit, action or proceeding brought against Grantor with respect to any Collateral, (6) settle, compromise or adjust any suit, action or proceeding described above, and in connection therewith, give such discharges or releases as the Secured Parties may deem appropriate, (7) license, or, to the extent permitted by an applicable License, sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any Copyright, Patent or Trademark throughout the world for such term or terms, on such conditions and in such manner as the Secured Parties shall in their discretion determine, and (8) sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Secured Parties were the absolute owners thereof for all purposes; and

(iv) to do, at the Secured Parties’ option and Grantor’s expense, at any time, or from time to time, all acts and things which the Secured Parties may reasonably deem necessary to protect, preserve or realize upon the Collateral and the Secured Parties’ security interest therein in order to effect the intent of this Security Agreement, all as fully and effectively as Grantor might do.

(b) The Secured Parties agree that, except upon the occurrence and during the continuation of an Event of Default, they shall not exercise the power of attorney or any rights granted to the Secured Parties pursuant to this Section 6. Grantor hereby ratifies, to the extent permitted by law, all that said attorney shall lawfully do or cause to be done by virtue hereof. The power of attorney granted pursuant to this Section 6 is a power coupled with an interest and shall be irrevocable until the Secured Obligations are completely and indefeasibly paid and performed in full and the Secured Parties no longer have any commitment to make any Loans to Grantor.

(c) If Grantor fails to perform or comply with any of its agreements contained herein and the Secured Parties, as provided for by the terms of this Security Agreement, shall perform or comply, or otherwise cause performance or compliance, with such agreement, the reasonable expenses, including reasonable attorneys’ fees and costs, of the Secured Parties incurred in connection with such performance or compliance, together with interest thereon at a rate of interest equal to the highest per annum rate of interest charged on the Loans, shall be payable by Grantor to the Secured Parties within five (5) business days of demand and shall constitute Secured Obligations secured hereby.

10

7. Rights And Remedies Upon Default. Beginning on the date which is ten (10) business days after any Event of Default shall have occurred and while such Event of Default is continuing:

(a) Upon the written consent of the Majority Lenders or C5, the Secured Parties may exercise in addition to all other rights and remedies granted to them under this Security Agreement or the Notes all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, Grantor expressly agrees that in any such event the Secured Parties, without demand of performance or other demand, advertisement or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon Grantor or any other person, may (i) reclaim, take possession, recover, store, maintain, finish, repair, prepare for sale or lease, shop, advertise for sale or lease and sell or lease (in the manner provided herein) the Collateral, and in connection with the liquidation of the Collateral and collection of the accounts receivable pledged as Collateral, use any Trademark, Copyright, or process used or owned by Grantor and (ii) forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, assign, give an option or options to purchase or sell or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at public or private sale or sales, at any exchange or broker’s board or at any Secured Party’s offices or elsewhere at such prices as they may deem commercially reasonable, for cash or on credit or for future delivery without assumption of any credit risk. Grantor further agrees, at the Majority Lenders’ or C5’s request, to assemble the Collateral and make it available to the Secured Parties at places which the Secured Parties shall reasonably select, whether at Grantor’s premises or elsewhere. The Secured Parties shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale as provided in Section 7(e), below, with Grantor remaining liable for any deficiency remaining unpaid after such application. Grantor agrees that the Secured Parties need not give more than twenty (20) days’ notice of the time and place of any public sale or of the time after which a private sale may take place and that such notice is reasonable notification of such matters.

(b) As to any Collateral constituting certificated securities or uncertificated securities, if, at any time when Secured Parties shall determine to exercise their right to sell the whole or any part of such Collateral hereunder, such Collateral or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under Securities Act of 1933, as amended (as so amended the “Act”), the Secured Parties may, in their discretion (subject only to applicable requirements of law), sell such Collateral or part thereof by private sale in such manner and under such circumstances as the Secured Parties may deem necessary or advisable, but subject to the other requirements of this Section 7(b), and shall not be required to effect such registration or cause the same to be effected. Without limiting the generality of the foregoing, in any such event the Secured Parties may, in their discretion, (i) in accordance with applicable securities laws, proceed to make such private sale notwithstanding that a registration statement for the purpose of registering such Collateral or part thereof could be or shall have been filed under the Act; (ii) approach and negotiate with a single possible purchaser to effect such sale; and (iii) restrict such sale to a purchaser who will represent and agree that such purchaser is purchasing for its own account, for investment, and not with a view to the distribution or sale of

11

such Collateral or part thereof. In addition to a private sale as provided above in this Section 7(b), if any of such Collateral shall not be freely distributable to the public without registration under the Act at the time of any proposed sale hereunder, then the Secured Parties shall not be required to effect such registration or cause the same to be effected but may, in their discretion (subject only to applicable requirements of law), require that any sale hereunder (including a sale at auction) be conducted subject to such restrictions as the Secured Parties may, in their discretion, deem necessary or appropriate in order that such sale (notwithstanding any failure so to register) may be effected in compliance with the Bankruptcy Code and other laws affecting the enforcement of creditors’ rights and the Act and all applicable state securities laws.

(c) Grantor also agrees to pay all fees, costs and expenses of the Secured Parties, including, without limitation, reasonable attorneys’ fees, incurred in connection with the enforcement of any of their rights and remedies hereunder.

(d) Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Security Agreement or any Collateral.

(e) The Proceeds of any sale, disposition or other realization upon all or any part of the Collateral shall be distributed by the Secured Parties in the following order of priorities:

First, to each Secured Party in an amount sufficient to pay in full the costs of such Secured Party in connection with such sale, disposition or other realization, including all fees, costs, expenses, liabilities and advances incurred or made by any Secured Party in connection therewith, including, without limitation, reasonable attorneys’ fees;

Second, to the Secured Parties in amounts proportional to the Pro Rata share of the then unpaid Secured Obligations of each Secured Party; and

Finally, upon payment in full of the Secured Obligations, to Grantor or its representatives, in accordance with the UCC or as a court of competent jurisdiction may direct.

(f) The costs of enforcing or pursuing any right or remedy hereunder, including without limitation any repossession, sale, possession and management (including, without limitation, reasonable attorneys’ fees), and distribution shall be borne Pro Rata by the Secured Parties. Each Secured Party shall reimburse each other Secured Party, as applicable, for its Pro Rata share of all such costs promptly upon demand.

8. Actions by the Secured Parties and Amendments. All actions, omissions and decisions of the Secured Parties hereunder or any amendment of this Security Agreement or the Notes (each called herein an “Act of the Secured Parties”) shall be determined by and require the written consent of the Majority Lenders and C5. Each Secured Party shall take such actions and execute such documents as may be necessary to confirm or accomplish any Act of the Secured Parties. Notwithstanding the foregoing, the consent of each affected Secured Party shall be necessary to do the following to any Note:

(a) reduce the percentage of the principal and interest amount of any Loan;

12

(b) reduce the rate of or change the time for payment of interest on any Loan;

(c) reduce the principal of or change the fixed maturity of any Loan; or

(d) make any Loan payable in money other than that stated in the Note.

9. Unequal Payment by Grantor. Each Secured Party agrees that if it shall obtain or receive, through the exercise of any right granted to the Secured Parties under this Security Agreement, under the Notes or by applicable law, including, but not limited to any right of set-off, any secured claim under Section 506 of the Bankruptcy Code or any other security or interest, any payment or payments greater than its Pro Rata share of all Loans, as measured immediately prior to the receipt of such payment or payments, then (a) such Secured Party shall promptly purchase at par (and shall be deemed to have thereupon purchased) from the other Secured Parties, a participation in the Loans of such other Secured Parties, so that each Secured Party shall have received payments in proportion to its Pro Rata share immediately prior to such transactions and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that the Secured Parties share the benefits of such payment on a Pro Rata basis. The term “Loan” as used in this paragraph shall include accrued interest thereon.

10. Indemnity. Grantor agrees to defend, indemnify and hold harmless the Secured Parties and their officers, employees, and agents against

(a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with the transactions contemplated by this Security Agreement and (b) all losses or expenses in any way suffered, incurred, or paid by any Secured Party as a result of or in any way arising out of, following or consequential to the transactions contemplated by this Security Agreement (including without limitation, reasonable attorney’s fees and expenses), except for losses arising from or out of such Secured Party’s gross negligence or willful misconduct.

11. Reinstatement. This Security Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against Grantor for liquidation or reorganization, should Grantor become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of Grantor’s property and assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Secured Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Secured Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

12. Miscellaneous.

12.1 Waivers; Modifications. None of the terms or provisions of this Security Agreement may be waived, altered, modified or amended except by an instrument in writing, duly executed by Grantor, C5 and the Majority Lenders. Each Secured Party acknowledges that because this Security Agreement may be amended with the consent of C5 and the Majority Lenders, each Secured Party’s rights hereunder may be amended or waived without such Secured Party’s consent.

13

12.2 Termination of this Security Agreement. Subject to Section 11 hereof, this Security Agreement shall terminate upon the payment and performance in full of the Secured Obligations and the expiration or termination of any commitment of the Secured Parties to make Loans to Grantor.

12.3 Successor and Assigns. This Security Agreement and all obligations of Grantor hereunder shall be binding upon the successors and assigns of Grantor, and shall, together with the rights and remedies of the Secured Parties hereunder, inure to the benefit of the Secured Parties, any future holder of any of the Secured Obligations and their respective successors and assigns. No sales of participations in the Secured Obligations or any portion thereof or interest therein, and no sales, assignments, transfers or other dispositions of any agreement governing or instrument evidencing the Secured Obligations or any portion thereof or interest therein, shall in any manner affect the lien granted to the Secured Parties hereunder.

12.4 Governing Law. In all respects, including all matters of construction, validity and performance, this Security Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of New York applicable to contracts made and performed in such state, without regard to the principles thereof regarding conflict of laws, except to the extent that the UCC provides for the application of the law of a different jurisdiction.

12.5 Amendment and Restatement. Notwithstanding this amendment and restatement of the Original Security Agreements, (i) all of the indebtedness, liabilities and obligations owing by the Grantors or any other person under the Original Security Agreements shall continue as obligations hereunder, as amended hereby, and shall be and remain secured by this Security Agreement, (ii) the security interest granted by the Grantor to each Secured Party, in all of the Grantor’s rights, title and interests in, to and under the assets and properties of the Grantor pursuant to the Original Security Agreements (the “Existing Security Interest”) shall continue as a security interest hereunder, as amended hereby, and (iii) this Security Agreement is given as a substitution of, and not as a payment of the indebtedness, liabilities and obligations of the Grantor under the Original Security Agreements and neither the execution and delivery of this Security Agreement nor the consummation of any other transaction contemplated hereunder is intended to constitute a novation of the Original Security Agreements or the Existing Security Interest created thereunder.

12.6 Counterparts; Facsimile or PDF Copies. This Security Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same agreement.

Exhibit 99.3

IronNet Enhances its Network Detection and Response Solution to Provide

Broader Visibility of Cyber Threats

Receives Bridge Loan Financing from C5 Capital

MCLEAN, Va. (January 4, 2023) – IronNet, Inc. (NYSE: IRNT), an innovative leader Transforming Cybersecurity Through Collective Defense^SM, announced today enhanced capabilities of its network detection and response (NDR) solution, IronDefense. Recognized with the highest possible rating for Enterprise Advanced Security NDR Detection by SE Labs, IronDefense enables advanced and early visibility of unknown cyber threats that have slipped past endpoint and firewall detection and entered the network, whether on-premises or in the cloud.

With IronNet’s latest NDR updates, Security Operations Center (SOC) analysts can use IronDefense to detect VPN abuse such as high failed logins, password spray, and suspicious login times, any of which may be indicative of a brute force attack or unauthorized access attempts. Additional analytics updates enable detection of ongoing patterns of both fixed-interval and randomized-timing beacon activity as well as the detection of DNS tunnels using advanced encoding techniques being leveraged by attackers.

“We strive always to integrate best-in-class behavioral analytics to stay ahead of ever-changing tactics, techniques, and procedures (TTP) used by both nation-state adversaries and cyber-criminal organizations. Our goal is to deliver enhanced, broad, and early visibility of threats on enterprise networks–well before business impact,” said Raj Sivasankar, IronNet Vice President of Product Management.

The IronNet product team also has evolved IronDefense’s ease of use. Specifically, new sensors can now be auto-commissioned and auto-upgraded without requiring interaction from the SOC staff. From an ecosystem perspective, IronDefense enables customers using SentinelOne endpoint detection and response (EDR) to create and update network inventory as well as isolate a device in a SentinelOne-deployed network remotely from the Entity page in the IronDefense user interface. Similar capability exists for CarbonBlack and Crowdstrike endpoints.

IronNet continues to empower security teams to do more with fewer resources, especially as organizations struggle to find the level of security talent needed to secure the network against both advanced and less sophisticated cyber attacks. The IronDefense product updates, suitable for organizations with more cyber-mature teams, complement IronNet’s new proactive command and control (C2) threat intel feed, IronRadar^SM. Developed by IronNet’s team of elite threat hunters, IronRadar scours the internet fingerprinting servers to determine whether they are C2 infrastructure while being stood up, even before a cyber attack, such as ransomware, is initiated.

Available now on AWS Marketplace for a free 14-day trial, IronRadar allows organizations with less sophisticated cybersecurity infrastructure to proactively and automatically update their existing cybersecurity tools to be able to block suspicious and malicious indicators of adversary infrastructure as they are being set up.

IronNet’s advanced threat detection technology and proactive threat intelligence allow the IronNet Collective Defense^SM platform, powered by AWS, to serve as an early warning system for all companies and organizations participating in IronNet’s shared defense approach to cybersecurity.

Bridge Loan from C5 Capital

IronNet today also announced it has received a loan from an affiliated fund of existing stockholder C5 Capital Limited (C5) in the amount of $2 million. The terms of the loan from C5 are substantially similar to those of the loans from certain of IronNet’s directors and another lender in the aggregate principal amount of $6.9 million that were previously announced on December 20, 2022. The loan from C5 bears interest at an annual rate of 13.8% and has a maturity date of June 30, 2023. The promissory note issued to C5 is secured by substantially all of the assets of the Company, excluding the Company’s intellectual property, pursuant to the terms of a security agreement entered into in conjunction with the promissory note. The Company, C5 and the previous lenders intend to amend and restate their promissory notes and security agreements to make certain adjustments so that all lenders have identical loan documents.

About IronNet, Inc.

Founded in 2014 by GEN (Ret.) Keith Alexander, IronNet, Inc. (NYSE: IRNT) is a global cybersecurity leader that is transforming how organizations secure their networks by delivering the first-ever Collective Defense platform operating at scale. Employing a number of former NSA cybersecurity operators with offensive and defensive cyber experience, IronNet integrates deep tradecraft knowledge into its industry-leading products to solve the most challenging cyber problems facing the world today.
