Leading south west legal practice Michelmores is
implementing a secure remote access system from AEP Networks to support its
growing demand for mobile working and to provide a contingency for
emergency situations. The 260-staff Exeter and London-based firm is also
considering using the system to create secure portal areas on its network
which will be accessible to clients and partners.
Security was a key requirement for Michelmores, which provides legal
services to major institutions, large companies, government departments and
public bodies nationwide. The AEP Netilla Security Platform (NSP) Secure
Sockets Layer Virtual Private Network (SSL VPN) appliance has been
configured to perform an in-depth integrity scan of all devices before
permitting web-based thin client access to Michelmores' Wide Area Network
(WAN) via Citrix.
"Based on the system's client integrity check, users will be automatically
allocated one of five pre-defined access levels to company applications and
resources. The most trusted level -- the only one that will allow
information to be transferred to and from our WAN -- will be reserved for
those identified as using Michelmores provided kit," said Simon Clarke, IT
Manager for Michelmores, who has been working with specialist remote access
systems integrator Community Internet to roll out the NSP.
The NSP was installed by Community Internet in June 2006 following a
successful one-month trial. It currently supports 25 concurrent users who
are given access to Microsoft Office applications, email and Michelmores'
time recording and digital dictation software. It is being rolled out to
more users and is expected to be taken up by around 35 percent of the
workforce initially.
NSP replaces a Cisco 'thick' client VPN that did not use Citrix.
Michelmores had outgrown the system and wanted a more scalable solution
with greater functionality, a high level of security and tight integration
with Citrix. Working with Community Internet, Michelmores evaluated SSL
VPNs and found that the NSP met a key requirement of securely handling the
complex issues involved in allowing end users to synchronise Microsoft
Outlook email onto their encrypted laptops.
"It sounds easy, but we found that NSP was one of the few systems we could
rely on to synchronise Outlook while maintaining effective security. This
was important to us as we wanted users to have access to email while
offline rather than only while connected. A synchronized and encrypted
local copy of their emails on their PC hard disk was the only option," said
Clarke.
Business continuity was also one of the drivers for the new system, which
is configured so that it can easily be modified to support additional users
in the event of an emergency.
"If we were a City law firm we would probably be able to relocate to one of
many contingency centres that are operated in London. But in the South
West of England there are no such facilities and remote-working technology
is one way for us to remain productive in the event of a disaster,"
explained Clarke.
Business Continuity is also supported by Michelmores' use of a wireless
broadband connection from Community Internet. The Red Kite high
performance WiMAX-ready fixed-wireless 5MB connection is delivered to a
wireless base unit in the Michelmores' Exeter office.
"In an emergency, if we unexpectedly need to have a bigger connection to
support more staff working remotely via the NSP, one phone call to
Community Internet can instruct them to scale our wireless link at the
touch of a button to 10 or even 20 MB. With fibre or copper links we'd have
a 40-day lead time to do this."
A mobile phone-based two-factor authentication system from VASCO has also
been implemented with the NSP to enhance security. The VASCO Java client
installed on employee mobile phones will generate a random code that users
must key in before accessing the WAN.
Longer term plans involve using the NSP's secure V-Realms facility to
create secure areas on the Michelmores network where clients can access
information, as well as a partner sections to facilitate greater
collaborative working.
