Item 4.01   Changes in Registrant’s Certifying Accountant.

On July 23, 2007, the Board of Directors of Vector Intersect Security Acquisition Corp. (the “Company”) dismissed Goldstein Golub Kessler LLP (“Goldstein”) as the Company’s principal accountants.  

During the Company’s two fiscal years ended December 31, 2006 and the subsequent interim period ended July 23, 2007, there were no disagreements with Goldstein on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to their satisfaction, would have caused them to make reference in connection with their opinion to the subject matter of the disagreement.

The audit reports of Goldstein on the consolidated financial statements of the Company and its subsidiaries as of and for the years ended December 31, 2005 and December 31, 2006 and as of and for the interim period ended May 1, 2007 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

There were no “reportable events”, as that term is described in Item 304(a)(1)(v) of Regulation S-K, for the two years ended December 31, 2006 and the subsequent interim period ended July 23, 2007.

Attached as Exhibit 16.1 is a copy of Goldstein’s letter addressed to the SEC relating to the statements made by the Company in this Current Report on Form 8-K.
