Energis Chooses Aladdin eSafe to Tackle Spam Problem

CHICAGO, March 21, 2005, - Aladdin Knowledge Systems Ltd. (NASDAQ: ALDN) today announced that UK-based Energis selected Aladdin eSafe to tackle the growing problem of spam and virus attacks.

A leading data, voice, call center, Internet and hosting services provider, Energis deployed the Aladdin eSafe content security solution on their network gateway, allowing them to centrally monitor behavioral patterns and prevent the entry of malicious content, including spam. By shutting out spam, Aladdin eSafe significantly reduced the number of emails Energis has to process. Within the first seven days of going live, Aladdin eSafe identified more than 862,000 spam messages out of approximately 1.2 million emails.

As the main provider of Internet and telecoms services to over 40 FTSE 100 companies and with a commitment to deliver its solutions at a consistent level of 99 percent availability, it is essential that Energis' systems run as efficiently as possible. The increase in spam was reducing the capacity of its systems, costing Energis valuable time and money. Aladdin eSafe ensures that these spam emails are filtered out while preventing legitimate emails that are important to the business from being blocked.

"Aladdin is a company that really wanted to build a relationship with Energis, and genuinely wanted to do all it could to help and provide the best security solution for our organization," said Graham Smith, security operations manager at Energis. "eSafe has proven to be extremely reliable in tackling Energis' problem with spam emails. It has ensured that we can continue to provide our customers with the excellent service they both expect and require from us."

Aladdin has worked closely with Energis to ensure that eSafe would allow it to efficiently manage the huge scale of emails entering its systems. Since using eSafe, Energis' issue with spam has been diminished. The amount reaching its servers has been reduced by 85 percent, resulting in massive time and resource savings for the company.

"As an integrated solution delivering all components required for complete corporate content security, eSafe is protecting Energis' entire enterprise from viruses, spam, worms and other malicious code threats," said Shimon Gruper, vice president of technologies for the Aladdin eSafe Business Unit. "Since using eSafe, Energis' issue with spam has been greatly reduced, freeing up the IT team's time and ensuring the company no longer needs to purchase additional, costly servers and other equipment to handle the previously massive levels of spam."
