With fraudulent, inappropriate and offensive emails being delivered in vast quantities to businesses every day, anti-spam software is a vital component of your network security strategy. Spam wastes network users' time and network resources, and can also be dangerous.

We offer you a fast set-up and a high spam detection rate using Bayesian and statistical filtering ,very low false positives through automatic whitelist, and the ability to automatically adapt to your email environment to constantly tune and improve spam detection. Spam filter will eliminate over 98% of the spam and phishing emails from your network.

Information security is a business concern for all organizations. With security threats increasing in number and sophistication, businesses want to gain protection, control, and visibility over their security systems, preventing incidents and threats that disrupt productivity, impact customer relationships, and erode profits. Government regulations concerning the protection of information also add to the growing emphasis on security. Next Steps

A systems approach to security enables tighter integration with the network, which delivers better overall security. Point-product strategies rely on connecting disparate products that address individual aspects of security whereas an integrated, collaborative, adaptive approach uses the network to provide consistent and thorough protection to all parts of the organizational infrastructure.

Organizations want to align security policy to their business requirements, while having the agility to adapt easily as needs change. Integrating security into the network enables security professionals to control, deploy, and enforce policies according to business requirements, remaining secure yet flexible and agile.

Most firewalls are purchased with network security in mind, but the type of security is rarely defined. Webangel's network engineers work to understand how a network is used and then design the security to protect it. The design for the firewall can evolve as the company changes with security and services to meet your needs over the long term.

This evolutionary process doesn't have to start with a small firewall that is solely dedicated to security. Other services and "add-ons" can be designed-in to address various network or company needs. For instance:

• VPN - Secure remote access that encrypts data between the main office and a remote network or computer. More...
• Bandwidth Monitoring - this add-on gives text & graphic information on how connectivity resources are used.
• Web Caching - Can save up to 40% of the network's bandwidth by caching frequently visited web sites.
• Web Blocking - Allows the firewall to block traffic to many sites that are cause for concern or liability.
• DMZ Network - A DMZ network is a second network behind the firewall used for services that need to be accessed directly from the Internet, such as mail or web services. The DMZ network is still protected by your firewall (so it's safer to run systems that do not have built-in firewall capabilities.) Basically, the private network can access the Internet and the services on the DMZ, but the servers on the DMZ and requests from the Internet cannot reach the private network.

Webangel's staff will help you select the security design and services to meet your needs. A network engineer will then take care of the setup and installation of the firewall on your network.

Caching is a way to store requested Internet objects (e.g. data like web pages) available via the HTTP, FTP, and Gopher protocols on a system closer to the requesting site. Web browsers can then use the local Squid cache as a proxy HTTP server, reducing access time as well as bandwidth consumption. This is often useful for Internet service providers to increase speed to their customers, and LANs that share an Internet connection. Because it is also a proxy (i.e. it behaves like a client on behalf of the real client), it can provide some anonymity and security. However, it also can introduce significant privacy concerns as it can log a lot of data including URLs requested, the exact date and time, the name and version of the requesters' web browser and operating system, and the page that the requester got to the requested page from. It can be also used to restrict users access to the Web, stop them from lookng at unsolicited pages during work hours and protect your network from viruses and worms(web content can be scanned before delivery to end user).

ModSecurity is a web application firewall (WAF). With over 70% of all attacks now carried out over the web application level, organisations need every help they can get in making their systems secure. WAFs are deployed to establish an external security layer that increases security, detects, and prevents attacks before they reach web applications. It provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring and real-time analysis with little or no changes to existing infrastructure.

The basic goal of the High Availability Linux project is to:
Provide a high availability (clustering) solution for Linux which promotes reliability, availability, and serviceability (RAS) through a community development effort.
The Linux-HA project is a widely used and important component in many interesting High Availability solutions, and ranks as among the best HA software packages for any platform. We estimate that we currently have more than thirty thousand installations up in mission-critical uses in the real world since 1999.
