ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

     On October 2, 2003, the Board of Directors of V-ONE Corporation  ("V-ONE"),
upon the recommendation of its Audit Committee,  approved the dismissal of Ernst
& Young LLP as its independent  auditors and the engagement of Aronson & Company
as its new independent auditors.  This determination followed V-ONE's efforts to
contain costs and seek an independent auditor better suited to its size. Aronson
& Company will audit  V-ONE's  financial  statements  for the fiscal year ending
December  31, 2003,  and is expected to complete the audit of V-ONE's  financial
statements  for the fiscal year ended December 31, 2002 and to issue a report on
such financial statements in conjunction with the filing by V-ONE of its amended
Annual Report on Form 10-K for the fiscal year ended December 31, 2002.  Aronson
& Company  also is  expected  to review  V-ONE's  financial  statements  for the
quarters ended March 31, 2003 and June 30, 2003 in  conjunction  with the filing
by V-ONE of its amended Quarterly Reports on Form 10-Q for such periods.

     During the two years ended  December  31,  2001 and the most recent  fiscal
year of V-ONE  ended  December  31,  2002 (which year was not audited by Ernst &
Young LLP), and the subsequent  interim  period through  October 2, 2003,  there
were no  disagreements  between  V-ONE and  Ernst & Young  LLP on any  matter of
accounting principles or practices,  financial statement disclosure, or auditing
scope or procedure, which disagreements,  if not resolved to Ernst & Young LLP's
satisfaction,  would  have  caused  Ernst & Young LLP to make  reference  to the
subject  matter  of the  disagreement  in  connection  with its  reports  on the
financial  statements  of V-ONE for the years ended  December 31, 2000 and 2001.
There were no "reportable events" as that term is described in Item 304(a)(1)(v)
of Regulation S-K.

     The audit reports of Ernst & Young LLP on the financial statements of V-ONE
as of and for the fiscal years ended  December 31, 2000 and 2001 did not contain
any  adverse  opinion or  disclaimer  of  opinion,  nor were they  qualified  or
modified as to uncertainty,  audit scope or accounting principles.

     V-ONE has requested  Ernst & Young LLP to furnish it a letter  addressed to
the U.S.  Securities and Exchange  Commission stating whether it agrees with the
above statements.  A copy of that letter,  dated October 7, 2003, is filed as an
exhibit to this form 8-K.

     During the two most recent  fiscal years of V-ONE ended  December 31, 2002,
and the subsequent interim period through October 2, 2003, V-ONE did not consult
with Aronson & Company  regarding any of the matters or events set forth in Item
304(a)(2)(i) and (ii) of Regulation S-K.


ITEM 7.  EXHIBITS.

Exhibit 16.1    Letter  from  Ernst  &  Young  LLP to the  U.S.  Securities  and
                Exchange Commission regarding change in certifying accountant.



                                   SIGNATURES

     Pursuant to the  requirements  of the Securities  Exchange Act of 1934, the
registrant  has duly  caused  this  report  to be  signed  on its  behalf by the
undersigned hereunto duly authorized.
