We hereby consent to the use of the following information derived from
"Federal IT Market Forecast, FY2003-FY2008," an INPUT report, and to all
references to us included in or made part of DigitalNet Holdings, Inc.'s
Registration Statement on Form S-1, any related prospectus and any future

According to INPUT, an independent federal government market research
firm, the overall federal information technology market for
vendor-furnished information systems and services is expected to grow
at a compound annual growth rate of 8.5% from $45.4 billion in federal
fiscal year 2003 to $68.2 billion in federal fiscal year 2008.
Federal government spending on outsourced information technology
services, our primary market, is expected to grow from $8.9 billion in
fiscal year 2003 to $16.1 billion in fiscal year 2008, a compound
annual growth rate of 12.6%, according to INPUT.
According to INPUT, the Department of Defense's spending on information
technology services and solutions is expected to increase from $21.2
billion in federal fiscal year 2003 to $31.5 billion in federal fiscal
year 2008.
For example, the reform of the GSA Multiple Award Schedule in 1998
allowed agencies to take advantage of ordering services through
pre-approved vendors and as a result, according to INPUT, the federal
sales cycle has declined approximately 29% from federal fiscal year
1998 to federal fiscal year 2001.
According to INPUT, federal government spending on network services and
network management is expected to grow at a compound annual growth rate
of 9.6% from $2.7 billion in federal fiscal year 2003 to $4.3 billion
in federal fiscal year 2008.
