ProSecure STM Series Summary:

Additional Information » Request a Quote » STM Reference Manual » ProSecure STM Datasheet

The ProSecure™ STM series of gateway security appliances uses a patent-pending Stream Scanning architecture to deliver best-of-breed business security. ProSecure™ employs millions of signatures to protect against known threats, and in-the-cloud zero-hour protection technology to proactively discover and block any suspected threats that have not yet been identified. Likewise, the NETGEAR® in-the-cloud Distributed Spam Analysis architecture shields networks from spam, phishing attacks, and other Email-borne threats.

Other solutions significantly dilute the efficacy of their offering by either utilizing open source or cutting essential features and services from their enterprise products to fit an SMB price point. But through its patent-pending Stream Scanning architecture, NETGEAR® provides complete enterprise-grade solutions, including advanced scanning technologies such as its comprehensive anti-malware engine, in-the-cloud Distributed Spam Analysis, and a proactive behavioral defense system that eliminates the gap between a vulnerability being exploited and the time it is fixed.

With ProSecure™ STM, subscriptions are simple with no per-user licensing. ProSecure™ Web and Email subscriptions each contain comprehensive protection for an unlimited number of users.

Sizing Guidelines

ProSecure™ STM appliances manage an organization's Internet usage and protects these organizations from Internet borne malware, spam, viruses, and inappropriate web surfing. With the ProSecure™ STM appliance sitting between the organization and the Internet, it is critical that the STM appliance is sized appropriately and matches the performance needs of the organization.

There are no industry-standard metrics for determining the model to select, as every organization is unique and displays different Internet usage characteristics. As such, NETGEAR® uses several specifications to evaluate the applicability of an STM appliance:

Throughput:

A starting point is to estimate the throughput your organization requires between its internal network and the Internet. As the STM appliance sits between your internal network and the Internet, this throughput number is the total amount of traffic that can be passed with the STM in place.

Concurrent Clients:

The number of concurrent clients represents the maximum number of currently active clients that can simultaneously access the Internet through the STM. NETGEAR® STM Appliances' Concurrent Client rating is a number that is measured assuming that each active client is currently engaging in an "average" web browsing session with multiple connections to multiple websites.

In general, your organization's concurrent client count should be less than the total number of users in your organization. For instance, if your organization has 1000 users, perhaps only 800 of those users have Internet access via a computer. Moreover, on the average, perhaps only 75% of those users are in the office at any point in time (75% x 800 = 600 users). Lastly, you may perhaps estimate that only 50% of those users (50% x 600 = 300 users) are actually on the Internet browsing web traffic at a given time.

Concurrently Scanned HTTP Connections:

Users who are actively browsing the Internet can typically be estimated to have 5 active HTTP connections at any point in time with a 60% rate of concurrency (yielding 3 connections). This number accommodates averaged situations where some users are heavily browsing the web or using Internet bandwidth intensive applications. Note that the peak number of connections can exceed these estimates if there is extraordinarily heavy usage of Internet bandwidth or connection intensive applications such as Peer 2 Peer applications are being used.

Email Throughput:

The rate at which users send and receive Emails varies widely in organizations, and is also dependent on the amount of spam an organization is receiving. For instance, if users, on the average, send and receive 30 legitimate emails per hour and 70% of Email traffic is SPAM, then each user will contribute 100 Emails per hour to the overall system load. A 200 user organization could then be expected to experience an Email load of 200,000 messages per hour.
