Freedom from virus attacks and hackers was a prime necessity for us.

Mr. Edwin Jovin

Zanzibar Telecom Ltd.


Mr. Edwin Jovin, the Network Administrator at Zantel, was looking for a solution that could give them freedom from virus attacks and hackers.

The security issues which they faced were:

Penetrable Network Periphery

The Zantel network comprised of confidential data, business secrets and other client sensitive information. All these were under a constant threat from DoS, DDoS, IP Spoofing, Man-in-the-middle and other network attacks. Jovin said, “Protection against intentional and unintentional intrusion attempts was necessary for us”.

Torrent of Spam Mails

Jovin wanted to put a full stop, to the amount of mails received as Spam. These mails often made the employees waste a considerable amount of time, energy and productivity in reading and deleting them. Some Emails were such that lured the employees to click malicious links ultimately giving way to troubles for the organization and the employees.

Lack of User Visibility

Jovin wanted to keep a track of user activity in the network. They did not have a reporting solution that would give them reports, based on identity for managing the activities of the staff. Hence, he said, “We were unknown to the activities going on in the network”.

The Cyberoam Solution

Zantel explored the market to find a solution that would meet their requirements. Having considered many solutions like WatchGuard, Jovin ended his search on Cyberoam. They purchased Two (2) CR750ia appliances, all of which are deployed in Gateway Mode at the Head Office. The benefits noticed after deploying Cyberoam are:

  • Impenetrable Network Periphery

    Cyberoam’s ICSA and Check Mark 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. It also provides a Fusion technology enabling the administrator to create policies for multiple features through a single interface.

    With a comprehensive database of 4000+ IPS signatures, Cyberoam’s Intrusion Prevention System (IPS) protects Zantel’s network from spoofing, DoS and DDoS attacks in addition to keyloggers and Trojans. It also provides signature updating facility that updates the signatures regularly and provides zero-hour protection against latest attacks.

    Jovin said, “Thankfully, Cyberoam has made us tension free from hackers and threats that can invade our network’s privacy”.

  • User Integration

    Jovin said, “We integrated Cyberoam with our Active Directory as well as used Cyberoam’s Local Authentication to bring the Zantel users under its scrutiny”. This feature greatly helps him to create policies for controlling the activities based on identity of the users rather than IP Addresses. Thus it helps him to know what is going on in the network.

  • Torrent of Malware and Spam Controlled

    Cyberoam’s Gateway Anti-Virus and Anti-Spyware solution scans the web, Email and VPN traffic protecting against malware including viruses, spyware, worms, keyloggers and Trojans. In addition, the Anti-Virus blocks attachments for specified file types like executables, media files and password-protected attachments before these threats enter and destroy the network.

    Cyberoam’s Check Mark certified Anti-Spam solution provides Spam detection rate of over 98% and false positive rate of 1 in 1 million. This ensures that legitimate mails reach safely to employee’s inboxes while Spam is kept at bay leading to minimal business loss. In addition, the Recurrent Pattern Detection (RPD) technology which is content and language independent, offers real-time protection from the very first moment a new outbreak emerges.

    After deploying Cyberoam Jovin said, “Cyberoam has filtered a considerable amount of Spam mails, providing a clean mailbox”.

  • Complete Visibility- Who is doing What?

    Cyberoam’s reporting feature enables the company to know “Who is doing What?” across the network and remote locations. Cyberoam’s on-appliance reporting solution eliminates the need for independent reporting solution thereby reducing cost and need for extra peripherals. By providing 1000+ granular reports, the company can keep a track of each employee and know the work trend. Hence based on the trend, the company can also tweak the business policies to stop the surfing habits of the users.

    On the other hand the employees knowing that their activities are being monitored will work accordingly, leading to increased productivity.

    Jovin said, “Cyberoam’s reporting solution has helped us a lot in knowing the users surfing trend and taking actions accordingly”.

  • To Conclude

    Jovin said, “Cyberoam proved to be an Internet Security solution with many hidden benefits. Without being aware of it, the employees’ Internet usage discipline improved and the fact that someone is watching what they are doing, helped”.
