Next-gen firewalls: Off to a good start
May 7, 2012
When we tested four next-gen firewalls strictly on performance, we found that the products could forward packets at impressive rates, but throughput dropped when advanced security features were...
Next-gen firewalls require external visibility tools
May 7, 2012
Knowing what's happening on your network is a pre-requisite to controlling the traffic. We call that visibility because it combines all of the information the firewall knows, including session and...
Palo Alto next-gen firewall stacks up well
May 7, 2012
Palo Alto Networks has bet everything on being a next-generation firewall. Without the next-generation hook, Palo Alto has little chance at breaking into the established world of firewalls, and...
SonicWall stands tall in SSL decryption testing
May 7, 2012
If one of the main advantages of a next-generation firewall is application and protocol identification and control, then SSL decryption is a basic requirement. We looked at the SSL decryption...
Check Point takes best approach to URL filtering
May 7, 2012
URL filtering has become a "checkbox" feature on most Unified Threat Management firewalls, and no wonder: it doesn't require a lot of imagination to do it right, and it's hard to really differentiate...
Basic firewall functionality: Check Point's maturity shows through
May 7, 2012
Enterprise firewalls must have policies to control traffic, ability to create site-to-site VPNs using standards-based IPsec, translate addresses and port numbers (NAT) when needed, and apply basic...
How we tested next-generation firewalls
May 7, 2012
We tested next generation firewalls by looking at seven separate areas that we felt would be important to network managers trying to deploy these products in enterprise networks.
Fortinet has highest catch rate in IPS testing
May 7, 2012
We tested the intrusion prevention capabilities of each of the next-generation firewalls to determine how well they work and how the IPS integrates with system management.
Fast-forwarding firewall faceoff
April 23, 2012
Next-generation firewalls claim to identify application-layer attacks and enforce application-specific policies while delivering top-notch performance, even with advanced security features turned on.
Scaling Up With SonicWALL's Supermassive
April 23, 2012
SonicWALL's initial response to results of our SSL decryption tests was "you've got to be kidding - we go way faster than that." Indeed, the vendor's internal tests showed the Supermassive decrypting...
How we tested the next-generation firewalls
April 23, 2012
We assessed performance using three sets of tests, covering forwarding rates with mixed HTTP content; rates with static HTTP content, and TCP connection behavior. Two pairs of Spirent Avalanche 3100...
WampServer delivers a smart, Windows-friendly platform for Apache, MySQL and PHP-based apps
April 23, 2012
While many popular website applications (WordPress, Drupal, Joomla, etc.) are open source and therefore freely available, running these PHP-based apps on a Windows IIS web server requires a bit of...
Arista 10G switch: Fast and flexible
March 26, 2012
Packing 384 10G Ethernet ports into an 11-rack-unit form factor is only the beginning for Arista Networks' DCS-7508 data center core switch.
How we tested Arista's DCS-7508 switch
March 26, 2012
We assessed the Arista DCS-7508 with tests of performance and power consumption. The performance tests used the Spirent TestCenter test instrument to measure layer-2 and layer-3 unicast throughput...
Three-stream Wi-Fi hits the mark
March 26, 2012
The rapid adoption of 802.11n has become a significant milestone in the history of wireless LANs. The MIMO-based technologies used in most 802.11n systems provide enough throughput, reliability, and...
A note on nomenclature
March 26, 2012
WLAN devices (access points and clients) supporting (up to) three spatial streams are often denoted as "3x3" devices, referring to the minimal number of transmitters and receivers required to make...
What you need to know about 802.11ac
March 26, 2012
A question we're hearing with increasing frequency concerns the upcoming 802.11ac standard, which promises to do to 802.11n what .11n did to .11g. While the IEEE 802.11ac standard likely won't be...
Tips for buying a three-stream access point
March 26, 2012
The decision to buy a three-stream access point (or likely, a whole lot of these) in an enterprise environment is more complex than throughput alone. You need to begin with overall IT requirements,...
Review: HP, IBM, CA deliver highly scalable network management suites
March 12, 2012
A network that measures downtime in millions of dollars per minute (or per second!) needs a serious, enterprise-level network management tool. Nothing less will do.
How we tested network management wares
March 12, 2012
We evaluated each product in several different areas: Discovery and enumeration of devices and computers, support for a variety of device manufacturers and device types, global directory integration,...
IPv6 deployment starts at the network edge
February 13, 2012
IT execs know they will have to deploy IPv6 at some point, but where to begin? One approach that establishes some  IPv6 capability without spending a lot of time or money is to start at the perimeter.
How to shop for Application Delivery Controllers
February 13, 2012
The key difference between Application Delivery Controllers (ADCs) is the way they can be integrated into your organization's network topology. Most organizations may deploy a server load...

We are in an awkward point in the history of the Internet. IPv4 address depletion has occurred yet we expect to use IPv4 for the next 15 to 20 years. Organizations see two paths before them. One...
First Look: Cisco Cius
February 13, 2012
We had a chance to see the Cius tablet at a Cisco office in Boston, and while we weren't able to bring it back to our own lab and pound on it, we did get a pretty good feel for what the Cius is and...
