Prior to Cyberoam installation, Guaranty Trust Bank was facing the following Internet
Bandwidth Congestion and Abuse
Guaranty Trust Bank (GTB) faced bandwidth congestion because the available
bandwidth wasn‘t being used optimally. Employees abused their unrestricted Internet
access through irresponsible activities like unproductive surfing, constant download of
music, videos and other bandwidth intensive content. These activities dominated most
of the available bandwidth leaving little room for actual work. Also, much of their
bandwidth was choked because of unsolicited spam.
Unhealthy Surfing Practices
A pressing concern for Mrs. Cox was unproductive, unhealthy and possibly illicit internet
surfing by employees. She wanted to monitor and control web surfing patterns of
individual employees, employee groups and the organization as a whole. She wanted to
pull the reins on Internet surfing to avoid employees from being distracted and the
network from being exposed to various cyber threats.
Mrs. Cox wanted to protect the GTB network from virus, root-kit, worm, Trojan and
spyware infections. These malware attacks often take a blended form through email
attachments, PDF, Word documents etc. and have the potential to corrupt useful files
and destroy important data. “I was looking for a highly dependable anti-virus solution
which would offer real-time protection from malware attacks including blended
threats”, she said. The organization also wanted to secure its entire email network
from newly emerging malware threats and reduce overall spam incidence.
The Cyberoam Solution
In order to address these challenges, Mrs. Cox looked into a number of security
products. However, after seeing a trial demo of Cyberoam, she decided to entrust
Cyberoam with the security of the entire GTB network. They deployed Seven (7)
Cyberoam Appliances in their Head Office and Branch Offices, and One (1) Cyberoam
Central Console (CCC) Appliance in their Main Data Center in Monrovia to manage
them all. All the appliances are deployed in gateway mode. The models and locations
of the appliances are given in the table below

The business benefits are as follows:
- Fortified Network Perimeter
Cyberoam‘s ICSA and Checkmark certified firewall provides granular access controls
over Internet traffic and network resources. Users are given controlled access to
network and internet resources, ensuring that no security loopholes are left open.
With a comprehensive database of 3000+ signatures, Cyberoam‘s Intrusion
Prevention System protects GTB‘s network against intrusion attempts, DoS and DDoS
attacks, malicious code transmission, Trojans, malware, backdoor activity, blended
threats and more.
- Controlled Internet Surfing
Cyberoam UTM‘s web content filtering feature controls Internet access in the Bank by
blocking inappropriate and unsafe Web content, including phishing and other malwareladen sites, and by stopping unauthorized download of bandwidth intensive streaming
content. “We have created policies for Web and Application Filter based on our
organization‘s requirements. The default polices themselves are quite comprehensive,
but the fact that those polices can be customized to our needs is simply great”, said
- Bandwidth Managed
Cyberoam allows user-based limit on bandwidth, access time and volume of data
transfer. “We allocated bandwidth based on website categories as well as
users/groups. It helps us in prioritizing business-critical applications and committing
bandwidth to critical users at all times”, said Mrs. Cox.
- Malware and Spam Corked
Cyberoam UTM‘s Gateway Anti-Virus and Anti-Spyware puts a stop-cork between the
GTB network and variants of Viruses, worms, Trojans, keyloggers, spyware and more,
thus avoiding any network downtime
Cyberoam‘s Check Mark Level 5 certified Anti-Spam solution checks all inbound and
outbound mails in the GTB network for spam. Irrespective of the language and the
content of the mail, spam is detected and action is taken. After installing Cyberoam,
the inboxes of the employees remain clean and spam free.
- Business Continuity Upheld
Cyberoam‘s IPSec VPN connectivity ensures secure connection between the Data
Center and Remote Sites. Remote Office users seamlessly access the network without
any worries of breakdown in Internet traffic. Threat-free Tunneling (TFT)-driven VPN
ensures that all such traffic is securely encrypted and no malware sneaks through it.
It is of utmost importance for the Data Center to have continuous Internet connectivity.
Hence, it is safeguarded with 2 ISP links. In case of failure of the main Internet link, the
Automatic Link Failover feature automatically switches the traffic to the backup link. So
the organization gets a transparent link failover faciltiy with no human interference and
100% Internet uptime.
- To Conclude
“Cyberoam is a conglomerate of multiple features in a single bundle which has helped
our organization in curtailing the cost of myriad applications and devices. It is very
reliable and affordable”, said Mrs. Cox.
