INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF CYBERX SECURITY UK LIMITED
 

Opinion

We have audited the financial statements of CyberX Security UK Limited (the ‘Company’) for the year ended 31 December 2024 which comprise the Statement of Comprehensive Income, the Balance Sheet, the Statement of Changes in Equity and notes to the financial statements, including a summary of significant accounting policies. 
The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (United Kingdom Generally Accepted Accounting Practice).

In our opinion, the financial statements:

give a true and fair view of the state of the Company’s affairs as at 31 December 2024 and of its loss for the year then ended;
have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the Directors use of the going concern basis of accounting in the preparation of the financial statements is appropriate.
Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company’s ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.
Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections of this report.

Other information

The Directors are responsible for the other information. The other information comprises the information included in the Directors' Report, other than the financial statements and our auditor’s report thereon. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.
 
Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of the audit:
 
the information given in the Directors Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and
the Directors Report has been prepared in accordance with applicable legal requirements.

Matters on which we are required to report by exception

In light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Directors Report.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
the financial statements are not in agreement with the accounting records and returns; or
certain disclosures of Directors remuneration specified by law are not made; or
we have not received all the information and explanations we require for our audit.
the Directors were not entitled to prepare the financial statements in accordance with the small companies regime and take advantage of the small companies’ exemption in preparing the Directors Report and from the requirement to prepare a Strategic Report.

Responsibilities of Directors

As explained more fully in the Directors Responsibilities Statement set out on page 2, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the Directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Directors intend either to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

Auditor's responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.
 
The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below.
 
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. 

Based on our understanding of the Company and its industry, we considered that non-compliance with the following laws and regulations might have a material effect on the financial statements: employment regulation, health and safety regulation and anti-money laundering regulation.

To help us identify instances of non-compliance with these laws and regulations, and in identifying and assessing the risks of material misstatement in respect to non-compliance, our procedures included, but were not limited to:
Inquiring of management and, where appropriate, those charged with governance, as to whether the company is in compliance with laws and regulations, and discussing their policies and procedures regarding compliance with laws and regulations;
Inspecting correspondence, if any, with relevant licensing or regulatory authorities;
Communicating identified laws and regulations to the engagement team and remaining alert to any indications of non-compliance throughout our audit; and
Considering the risk of acts by the company which were contrary to applicable laws and regulations, including fraud.  

We also considered those laws and regulations that have a direct effect on the preparation of the financial statements, such as tax legislation, pension legislation, the Companies Act 2006.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF CYBERX SECURITY UK LIMITED
 

In addition, we evaluated the Directors and management’s incentives and opportunities for fraudulent manipulation of the financial statements, including the risk of management override of controls, and determined that the principal risks were related to posting manual journal entries to manipulate financial performance, management bias through judgements and assumptions in significant accounting estimates and significant one-off or unusual transactions.

Our audit procedures in relation to fraud included but were not limited to:
Making enquiries of the directors and management on whether they had knowledge of any actual, suspected or alleged fraud;
Gaining an understanding of the internal controls established to mitigate risks related to fraud;
Discussing amongst the engagement team the risks of fraud; and
Addressing the risks of fraud through management override of controls by performing journal entry testing.

There are inherent limitations in the audit procedures described above and the primary responsibility for the prevention and detection of irregularities including fraud rests with management. As with any audit, there remained a risk of non-detection of irregularities, as these may involve collusion, forgery, intentional omissions, misrepresentations or the override of internal controls.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council’s website at www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Use of the audit report

This report is made solely to the Company's members as a body in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the Company's members those matters we are required to state to them in an auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and the Company's members as a body for our audit work, for this report, or for the opinions we have formed.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

1.


General information

On February 15, 2019, the Cyber X Israel LTD established a subsidiary in the U.K., CyberX Security UK Ltd.
The Company is a private limited company, limited by shares, incorporated in England and Wales. The address of its registered office is 1 Blossom Yard, Fourth Floor, London, United Kingdom, E1 6RS. The Company's registered number is 11828229.
On July 1, 2020, Microsoft Corporation acquired from Cyber X Israel LTD the UK subsidiary and the other subsidiaries. As a result of the acquisition, the three former subsidiaries became sister companies and, it was determined that the Company will provide research and development services to Microsoft. In consideration for those services Microsoft shall pay, on an arm's length basis, all the Company's operating expenses on a cost-plus basis.
The Company's functional currency is the same as the primary economic environment in which it operates. All figures are presented in Pounds Sterling (£), rounded to the nearest £. 

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with FRS 102 'The Financial Reporting Standard applicable in the UK and the Republic of Ireland' and the requirements of the Companies Act 2006

 
2.2

Going concern

The Company has net liabilities as at 31 December 2024 and limited activity during the year. The Directors have confirmation that the group will continue to support the Company to meet its obligations as they fall due.
The Company is not trading, but the Directors have not yet started formal procedures to close it down. Therefore, based on the group support noted above the Directors have concluded that it is appropriate to adopt the going concern basis in preparing the financial statements.

 
2.3

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is GBP. Monetary amounts in these financial
statements are rounded to the nearest £.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)


2.3
Foreign currency translation (continued)


Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the Statement of Comprehensive Income except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Statement of Comprehensive Income within 'finance income or costs'. All other foreign exchange gains and losses are presented in the Statement of Comprehensive Income  within 'administrative expenses'.

 
2.4

Taxation

Tax is recognised in the Statement of Comprehensive Income except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the Company operates and generates income.


 
2.5

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

 
2.6

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

 
2.7

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.8

Financial instruments

The Company only enters into basic financial instrument transactions that result in the recognition of financial assets and liabilities like trade and other debtors and creditors, loans from banks and other third parties, loans to related parties and investments in ordinary shares.
Debt instruments (other than those wholly repayable or receivable within one year), including loans and other accounts receivable and payable, are initially measured at present value of the future cash flows and subsequently at amortised cost using the effective interest method. Debt instruments that are payable or receivable within one year, typically trade debtors and creditors, are measured, initially and subsequently, at the undiscounted amount of the cash or other consideration expected to be paid or received. However, if the arrangements of a short-term instrument constitute a financing transaction, like the payment of a trade debt deferred beyond normal business terms or in case of an out-right short-term loan that is not at market rate, the financial asset or liability is measured, initially at the present value of future cash flows discounted at a market rate of interest for a similar debt instrument and subsequently at amortised cost, unless it qualifies as a loan from a Director in the case of a small company, or a public benefit entity concessionary loan.
