SentryFile is a web-based document system written as a set of .Net
Active Server Pages (ASP.net). The software runs on Microsoft
Internet Information Server (IIS). IIS is included
with Windows. The Microsoft Index Server provides full-text
searching capabilities. This software is also included with
Client computers access the system using Microsoft Internet
Explorer. If your client PC's already have Internet Explorer
installed then there is no requirement to install additional
client software. Simply provide your
staff with a URL that points to your SentryFile server.
All client workstations can scan documents to the system
directly through Internet Explorer with an ActiveX control.
This control provides imaging and Twain capabilities that
would normally not be available in a web application.
Users, Groups and Integration
SentryFile can authenticate users in numerous ways. The system
allows for authentication against a SentryFile internal
userlist, Windows Active Directory, POP/IMAP mail servers, FTP
Servers, or another SentryFile Server. The flexibility of
our authentication module gives you the ability to ensure
that "lost passwords" are a thing of the past.
Document Types / Data Storage
Documents that are uploaded to the system are stored in their
native format as flat files within the file system. They
are not encapsulated within a database. All index data
entered is stored in a Microsoft SQL Server Database.
If you don't own Microsoft SQL Server we include a copy
of the Free SQL Server Express Edition.
All data within the database is left in its natural state
(no encoding of the data values).
Tiff documents that are uploaded to the system are
auto-converted to PDF format. Scanned document
can also be recognized by our integrated Optical
Character Recognition (OCR) engine. This will
allow you to full-text search for documents that
have been scanned and OCR'd.
Microsoft Index Server provides full-text search. Index Server
works in the background with little or no administrative
interaction required. Essentially, Index Server "watches"
all documents within SentryFile. When new documents arrive
they are indexed for full-text searching. Natively supported
formats are all Microsoft Office Formats such as Word (DOC/DOCX),
Excel (XLS/XLSX), and PowerPoint (PPT/PPTX) etc. Other file types can
be supported by installing appropriate IFilters. IFilters are
typically provided by third parties free of charge. For instance,
Adobe provides a free IFilter for indexing PDF documents
with Index Server (We include the PDF iFilter with SentryFile).
IFilters are available for a wide range of
other products including Corel WordPerfect, XML, MP3 and more.
SentryFile can integrate within almost any backup system.
SentryFile resides within a folder typically called "c:\inetpub\wwwroot\sentryfile"
or similar. To backup the system simply include the installation
folder within your backup regimen. Many current customers use
technologies such as Tape backups, DVD backups, Network Attached
Storage (NAS) and removable hard disk technologies to achieve
their backup requirements.
Your SentryFile installation can be made available on the Internet
if you choose. Many of our clients prefer to have their installation
only available on their private LAN. Making your SentryFile
installation available over the Internet requires a full-time
dedicated Internet Connection. After this, it is necessary to
ensure that the IP address is available through any firewalls or
gateways installed within your organization. SentryFile supports
secure 128-bit encrypted connections, commonly used in e-commerce
and online banking applications. In order to achieve this it is
necessary to install a digital certificate within IIS, they can
be purchased through companies such as Verisign, or you can generate
