Business Editors/Technology Writers

BOSTON--(BUSINESS WIRE)--Jan. 30, 2001

Significant Upgrades to Protect Organizations from External and

Internal E-mail And Web Content Security Threats

Baltimore Technologies (Nasdaq:BALT) (LSE:BLM), a global leader in e-security, today announced the availability of upgrades to its award-winning MIMEsweeper(TM) product family for content security -- MAILsweeper for SMTP 4.2, MIMEsweeper for Domino R5, WEBsweeper 4 and e-Sweeper 1.1.

These comprehensive and flexible, policy-based content security solutions protect an organization's network and business from Internet e-mail, internal e-mail and Web content security threats providing the highest level of threat analysis on the market today.

"Customer demand is exploding for content security products that protect corporate intellectual property, ensure network integrity and offer businesses legal protection from employee violations of company policy concerning prohibited materials and the use of overburdened e-mail systems," said Chris Christiansen, vice president Internet Infrastructure and Security Software, IDC Research. "Baltimore Technologies offers very sophisticated e-mail and Web content analysis tools and is well-positioned in the content security market."

More than a quarter of the Fortune 200 companies use MIMEsweeper products, including seven of the top U.S. banks, to protect their networks and business.

"I would consider MIMEsweeper products to be a 'must-have' for any organization, if only to protect yourself," said Jeff Ferrera, e-mail administrator, Zenith Electronics. "We've been using MIMEsweeper for four years; I can't remember the last time we had an e-mail-borne virus in here. We also use additional capabilities, such as scanning outgoing mail for inappropriate information."

The new versions provide increased security, improved management capabilities plus feature and system upgrades that exemplify the depth and breadth of the Baltimore MIMEsweeper family. These include:

-- MAILsweeper for SMTP Version 4.2 -- Baltimore's leading e-mail content
security solution for Internet e-mail

-- WEBsweeper 4.0 -- New Web content security solution that enables customers
to implement content security policies on Web, HTTP and passive FTP transfers,
including personal Hotmail and Yahoo e-mail accounts

-- MIMEsweeper for Domino R5 -- Intranet e-mail and database content security
solution, now available for organizations using the Lotus Domino R5 platform

-- e-Sweeper Version 1.1 -- Solution for ISPs and ASPs to enable the provision
of a policy-based content security service to their customers

"Content security is much more than firewalls, stopping viruses and URL blocking. It's about agreeing upon policies and managing what information is moved by whom, when, where and how. This is only achievable with a comprehensive and flexible policy-based content security solution, such as MIMEsweeper," said Ken Sokol, senior product manager of Baltimore Technologies' Content Security Group. "The new upgrades in the MIMEsweeper solutions make it easier for organizations to protect themselves from degradation in network service, loss and corruption of data, as well as breaches of confidentiality."

The Baltimore MIMEsweeper solutions are best known for protecting organizations from content security threats, including e-mail-borne viruses and malicious codes, inappropriate images and text, encrypted objects and loss of confidential information. No other solutions on the market offer such comprehensive, in-depth content security from image analysis, unauthorized encrypted and signed objects, virus scanning, text analysis and adding disclaimers to contextual policy management that determines how content should be moved by who, what, how and when.

Upgrades To Meet Market Demand

According to a recent IDC report, the content security market grew from $33 million in 1998 to $66 million in 1999. With the integration of Web and e-mail content scanning for malicious code detection, IDC predicts this market will grow to $952 million by 2003. To meet this growing demand, Baltimore Technologies has made the following key enhancements to its MIMEsweeper solutions:

Baltimore MAILsweeper for SMTP 4.2

MAILsweeper for SMTP 4.2 now runs on the enhanced MIMEsweeper engine (v. 4). Additionally, it offers:

-- Clustering Capabilities -- MAILsweeper for SMTP v.4.2 now

offers clustering capabilities for supporting large,

distributed enterprise environments and provides a single,

central point of management. IT managers can better manage the

large volume of e-mails encountered on a daily basis, provide

higher uptime for mission-critical messaging systems and

obtain centralized policy management to support multiple

server configurations.

-- Real-Time Reporting -- MAILsweeper for SMTP v.4.2 has been

enhanced to provide real-time, direct auditing from the

MIMEsweeper engine directly into SQL databases. Now, IT

managers and other key decision makers can monitor activity in

near real-time to ensure e-mail security polices are

understood and complied with throughout the organization.

-- Enhanced Flexibility and Tools -- In direct response to

customer needs, MAILsweeper for SMTP v.4.2 now includes such

key features as enhanced file managers that allow

organizations to block MP3 files, as well as files by name or

file extension; a customized pattern matcher that allows end

users to define and identify file types they want to block or

manage (e.g. AutoCAD drawings); and expanded utilities that

allow IT managers to integrate MIMEsweeper with third-party

software for customized policy enforcement.

Baltimore MIMEsweeper for Domino R5

In addition to supporting the Lotus Notes R5 platform, MIMEsweeper for Domino has also been upgraded to provide:

-- Upgraded Archiving Capabilities -- Domino databases can fill

up fast. MIMEsweeper for Domino can help IT managers manage

the content being stored in the Lotus Notes databases by

setting archiving policies that can automatically store files

by date to ensure steady system performance.

-- Expanded Scalability -- MIMEsweeper for Domino supports

organizations of all sizes - from 50 to tens of thousands of

users.

-- Multiple Mailbox Support -- MIMEsweeper for Domino now

supports the multiple mailboxes feature that has been added to

the R5 platform.

Baltimore WEBsweeper 4

WEBsweeper has been significantly upgraded to meet the growing needs of Web-based activities within the organization. It runs on the same, powerful MIMEsweeper security and analysis engine contained in MAILsweeper for SMTP v.4.2, and now features:

-- Granular Policy Management -- IT managers can set security

policies for an enterprise, group or individual. This allows

organizations to clearly establish who can access what on the

Web, as well as where, when and why.

-- Bidirectional Content Analysis -- Organizations can now

analyze information downloaded from, as well as uploaded to,

the Web. This provides organizations the best tool for closing

the back door to a company's network and supporting already

existing SMTP policies. WEBsweeper can check content shared on

bulletin boards and Web-based e-mail, such as Hotmail or

Yahoo, as well as better protect against malicious codes and

loss of confidential information.

-- Real-Time Reporting -- As with MAILsweeper for SMTP v.4.2,

WEBsweeper provides real-time, direct auditing from the

MIMEsweeper engine directly into SQL databases.

Baltimore e-Sweeper v.1.1

e-Sweeper helps host and service providers protect their customers from a variety of different content security threats. Key enhancements made to v. 1.1 include:

-- Foreign Language Support -- e-Sweeper v.1.1 now offers support

for foreign language LEX lists for protecting against

profanity and other malicious content.

-- Oversized Message Management -- e-Sweeper has been upgraded to

help service providers better monitor incoming and outgoing

content by file type and file extension to maintain steady

system integrity.

-- Web Site Navigation -- e-Sweeper v.1.1 provides the ability

for host and service providers to easily navigate through Web

sites to provide a managed service for its customers.
