WebMARA

The Employee Internet Management System
that secures and improves your productivity

Does it take a long time for web pages to load on your company’s computers? Are your employees wasting bandwidth by downloading huge music or video files at work? Do you run any legal risks if an employee downloads questionable content from the Internet? If so, WebMARA is the solution.

WebMARA helps you save precious bandwidth by caching frequently accessed web pages locally, reducing the number of requests made on the Internet. This lowers traffic cost and optimizes the Internet access speed on each user's computer.

Besides speeding up web browsing, WebMARA also offers a user authentication feature, which compares users' login information with an external user database. This user authentication function, together with WebMARA's Internet content filtering feature, helps to identify the kind of content individual users access via Internet and eventually block it. WebMARA uses a comprehensive content classification database on the Internet. This optional content filtering protects employees and organizations from Internet misuse and abuse and reduces liability. By blocking content that is not related to work, productivity is improved and Internet bandwidth is conserved.

To improve productivity, reduce legal risks and ensure airtight security for your company network, WebMARA is your best choice.

WebMARA's Benefits

Anti-Virus and Contentfilter

Fine-grained control on anti-virus scanning and contentfilter reduces avoidable risks and ensures maximum browsing safety.

Bandwidth Savings

Highest bandwidth savings (BHR – Byte Hit Ratio) and bandwidth gain on the market. Supporting the most different content classes and including special optimizations for all popular services and sites.

Browsing Acceleration

Small objects are cached on and served from high performance Solid State Disks (SSDs). This improves Internet browsing experience significantly.

CDN Caching

Unique caching mechanism, highly accurate for arbitrary caching of videos and large rich media files from Content Delivery Networks (CDNs).

Powerful Policies

Define different policies for different groups of users. Use filtering based on user name/group, IP address, destination IP/domain/URL, MIME type, regular expressions and time-of-day filtering to define arbitrarily complex rulesets.

Features

Access Control

Provides easy and flexible access control to the Internet, e.g. by rules based on source type, user groups or single users, IP- and domain destinations, uploadable destination lists, mime-types, browsers, and time schedules.

Dynamic Anti-Virus Scanning

Seamless integration of anti-virus scanning does not require additional hardware for high-performance analyis, even for compressed archives.

Real-time Web Content Filtering

Local database and real-time cloud based ratings with over 100 predefined categories of Internet sites, realtime rating and analysis of threats and custom local policies.

Static & Dynamic Caching

Apart from static caching, dynamically served but unique content will be detected and can thus also be cached to improve response time and accelerate the performance of World Wide Web Internet applications.

Frequently asked questions

What are the benefits of Solid State Disks (SSDs)?

The performance of an HTTP proxy is limited by the performance of the used storage subsystem. The proxy needs to write a new object to disks in case of a Cache-MISS (the object is new and was not stored in the cache yet). In case of a Cache-HIT (the client requested an object that is already stored in the cache) it needs to read the object from the disks to serve it to the client. That means that each HTTP request results into a request to the disk subsystem in the worst case. Caching some parts of the requests in RAM helps to reduce the load to the disks a little bit but does not change the performance dramatically.

Performance without SSDs

Each enterprise SATA disk with 7.2k rpm can only handle approximately 100 requests per second. Faster SAS disks with 15k rpm can handle approximately 200 requests per second. That means that you need 30 SATA or 15 SAS disks to reach a performance of 3000 requests per second.

Performance with SSDs

We use high end SSDs to dramatically increase the performance. SSDs do not have any moving parts and have ultra low access times. High-End SSDs can do fifty thousand and more requests per second. The use of SSDs allows our solution to perform at many more requests per second than any other caching solution on the market.

You should not trust any vendor that tries to tell you that a HTTP proxy system that only uses SATA or SAS disks can do much more than 100-200 request per disk per second. This is just impossible because of the physical limitations of the disks. Disks have moving parts and it takes time to move the head to the requested position on the disk and read or write the object.
