Aladdin's eSafe did well enough and has some features that would be particularly useful during an outbreak, but performance was nothing special. Although eSafe is up to version 4 now, that version is purely appliance-oriented. The last version to support Exchange was 3.5, which the company still sells and supports (for now) despite its focus on moving away from that side of the business towards its Linux-based appliance version.

US mobile operator Verizon Wireless has filed a lawsuit in New Jersey, seeking an injunction against Passport Holidays of Ormond Beach, Fla., for allegedly violating federal and state laws by sending “tens of thousands” of unsolicited text messages to its customers.

As firewalls go, the CyberGuard SL3200 is a monster: a huge, noisy beast with performance that matches its rugged looks. The name denotes its capacity - 3.2 gigabits of total throughput, shared among a maximum of 26 Ethernet ports. Even more notably, it is able to multiplex several interfaces into a small number of very high-capacity pipes, all secured at wire speed.
Designed for high-demand environments, the box has all the HA features you'd expect - hot-swappable fans and power supplies, as well as RAID 5 storage, with an internal layout designed for maximum airflow and heat dissipation. Fail-over between two boxes is available if you have an extended license.

The SmartFilter product from Secure Computing was one of the earliest products to perform category-based URL filtering. Now in version 3.2, the basic principles of the product remain, with performance and management improvements aimed at making the task of controlling web access as simple as possible.
SmartFilter is intended to sit on a web proxy behind a firewall, or on the firewall itself. The product comprises agents that reside on the gateways, a management server that runs on Windows, Solaris and Linux servers, and a management console which can run on the same platforms. The server and console components are both Java based.

The Gordano Message Suite is not an anti-virus solution per se, it is a complete web-based messaging system with email, instant messaging, calendar feature and message filtering. The whole lot is managed from a central web console which is clean and consistent, with the exception of a Windows utility to add users to the database.

ViRobot is a lesser-known anti-virus solution from Korean developer Global HAURI. It is not really a newcomer - it has been in the market since 1998 - but it has taken until recent times to really start to make a mark in Western markets.

An Arizona court has outlawed text message spam for the first time in the U.S.

The SafeWord PremierAccess product immediately impresses as a solution that has been well considered from the outset. Developed around the dynamic password concept, it may nevertheless support smartcards and other tokens, and even biometrics. These methodologies may be mixed and matched depending upon the needs of the enterprise.

This solution is supplied as software, desktop or rack-mounted. Each network sensor is a separate appliance, handing high-availability, high-security 10/100 or gigabit monitored segments.Running on a hardened OS, based on Red Hat Linux, in a small installation it can be managed using a web-based interface, software or optionally as an appliance.

Policy enforcement is only as good as your management system allows, so a serious vulnerability could go unnoticed without prior knowledge of the problem.

Security Expressions allows deployment using no-agent technology to ensure that, once installed on either Windows NT or 2000 systems, the administrator can add machines within a group, that are required to adhere to the policies that pertain to that group.

Cobion's OrangeBox Web is a very similar product to DynaComm i:filter. Designed to integrate with a proxy server (for example, Microsoft ISA on Windows 2000/XP), it is also happy to sit on a number of popular Linux and Unix platforms. It can also be used as a proxy server in its own right if you have a small or medium-sized intranet network.

Another policy enforcement product, but with some added features that really give it some teeth, is iomart's NetIntelligence. As well as monitoring URL requests, it also looks at the network as a whole (hardware, software and all files) and can instantly detect whether any unauthorized changes have been made, or whether any prohibited content is suddenly present.

NetIQ MailMarshal was the sleeper hit of the recent email security Group Test. Can this New Zealand-based software development center make it two in a row with its WebMarshal browser control? The answer is a resounding yes.

BrightMail Anti-Spam is installed via a Java GUI or text install. India's Financial Express claims to have discovered that text messages sent to satellite TV users over Asian direct-to-home (DTH) satellites are effectively outside the scope of government surveillance technology. What arrives in our in-boxes these days is becoming progressively richer and fatter. The content includes HTML formatted rich text, hyperlinks and attachments of various types, including Office documents, databases, images, videos, etc. It is now estimated that more than 5 per cent of emails contain images.

Mail-Lock falls into a new category of email protection software, which the vendor calls email personal information containment, or EPIC for short. The software is claimed to allow users to carefully control what recipients of email can do with the messages and certain types of attachments. It does this using encryption technology to limit the functions within Outlook, as well as the length of time a message can be viewed by the recipient. The time control element is, as far as we can determine, the package's unique function within the POP-3/SMTP environment.
This version of Mail-Lock is designed to function as an add-in for Microsoft Outlook in all its desktop Windows variants, protecting the text of the email, as well as MS-Word, Excel and Powerpoint attachments. If an attachment from another application is attached and sent, Mail-Lock cannot control what happens to the attachment at the recipient's PC: it will simply open as normal. The company is developing versions for Outlook Express and Lotus Notes users, but no timescales for the updated releases have been made.

One very important area of email security is encryption. Unless you are using leased lines or virtual private networks (VPNs) to transmit information, the moment an email leaves your firewall it is at the mercy of the internet. Emails can be intercepted and read without your even knowing about it, which poses a terrible risk for corporate information. However, encrypting the email does give you a high degree of ­ reassurance.

PC Guardian provides a nifty little program called Encryption Plus Email that allows you to encrypt email body text and any attachments. The email product is very easy to install - full installation of the administration program takes less than a minute. The product is designed for individual use, so the administrator installs it on each workstation, then configures it centrally and rolls out the user files across the network. Encryption Plus Email is only available for Lotus Notes and Microsoft Outlook, but since these two cover a large proportion of companies this shouldn't be a problem.
