Cyberoam UTM Solution Leaves Nothing to Chance for IESL
About International Energy Services Limited (IESL), Energy Services
Established in 1990, International Energy Services Limited (IESL) is an indigenous Energy
Services Company set up with the aim of providing integrated and customer oriented services in
the oil and gas industry with specialized expertise for both onshore and offshore developments.
The company contains sensitive information that can be possibly targeted by attacks from external entities and outside access attempts. Thus they needed a strong Firewall and IPS solution.

Uninterrupted Internet Connectivity
The varied business requirements of Internet are as follows:
According to Mr. Williams Oluwagbenro O, the IT Manager at IESL, “Continuous Internet connectivity with no breakdown or downtime was the most important requirement for us. Apart from that, we also had to address these additional business challenges.”
Securing the Periphery & Warding off Intrusion Attacks
Mr. Williams wanted a solution that would control the entire Internet traffic and establish clear-cut
boundaries between the internal networks and the outside world. Servers in the internal
networks hosted sensitive information related to their engineering projects and employee private
details, which had to be protected.
Scheming Surfing Practices
Unmanaged Internet access presents many challenges and introduces unnecessary risk. When
workers inadvertently or deliberately access sites containing inappropriate, illegal, or dangerous
content, use instant messaging (IM) and peer-to-peer (P2P) applications, they expose
themselves to legal liability, and experience degraded network performance.
IESL wanted to secure its entire email network from newly emerging malware threats and reduce overall spam incidence. This was required to keep mails secure and in-boxes clean. The spam filtering was required to be totally automated and perform irrespective of the language and content of the mail with an absolute minimum amount of false positives - as no organization can afford to lose a single business opportunity should a legitimate email being wrongly classified as spam.
Load balancing & Failover
Continuous Internet connectivity with no breakdown or downtime was the most important requirement for IESL. "IESL requires load balancing and reliable performance while providing sufficient bandwidth for employees to access web-based resources safely and securely," says Mr. Williams.
The Cyberoam Solution
In order to address their challenges, IESL looked into a number of security products including GateProtect. However, after seeing a trial demo of Cyberoam, they took the decision of deploying the Cyberoam appliance -one (1) CR500ia at the head office in Lagos in gateway mode.
Identity based Security
Cyberoam UTM comes with a unique identity-based security solution which protects against
insider threats by giving complete visibility into “Who is doing What” in the network and allows
creation of user identity-based policies. Mr. Williams used Cyberoam‘s Active Directory (AD)
facility to achieve the task of integrating IESL‘s users in the network through a wizard to import
Firewall & Stopping Intrusions
IESL operates Cyberoam‘s ICSA and Checkmark Certified Perimeter Firewall between the Internet and the organization‘s network to establish a secure environment for the organization‘s computer and network resources. Coupled with Intrusion Prevention module, Cyberoam UTM can counter any Denial of Service attack. Mr. Williams now felt the network is secure.
IESL installed Cyberoam not only to manage employee Internet access, but to minimize the risk
of other web security threats. In addition, they chose Cyberoam to help improve employee
productivity and save network bandwidth. IESL uses Cyberoam to block access to specific
category of websites. They utilize the Cyberoam‘s reporting functionality to help identify
organizational risk levels for productivity, security and network bandwidth loss trends.
Spam Free Internet
Cyberoam‘s Check Mark Level 5 certified Anti-Spam solution offers 98% protection against
zero-hour attacks with .0001% false positive rate, minimizing the threat of business mail loss.
Round the Clock Connectivity
Cyberoam‘s Multilink manager increases the overall network performance by load balancing the network traffic between their two (2) ISP links terminating on them, delivering continuity in security. In case of failure, the load is automatically transferred to the other ISP link, which leads to 100% Internet uptime, and round the clock connectivity to their employees.
To wind up
"Of all the solutions we looked at, Cyberoam is definitely the best fit with our technology and our needs. We highly recommend them to any corporate that wants to get a lever on its security problems and prevent unauthorized intrusions, whether from outside or inside the network.” said Mr. Williams.
