Pending Acquisition Expected to Create One of the Largest Network Security Vendors, Offering the Most Complete Network Security Solution to Businesses of All Sizes

McAfee, Inc. (NYSE: MFE) today announced the execution of a definitive merger agreement to acquire Secure Computing Corporation (NASDAQ:SCUR) for $5.75 per common share in cash, without interest, representing an equity value for Secure Computing’s common stock of approximately $413 million in the aggregate. In addition, Secure Computing’s outstanding shares of preferred stock will also be redeemed for cash as part of the proposed transaction, which would represent approximately, calculated as of today’s date, an additional $84 million. In total, net of cash held by Secure, the proposed transaction would be valued at approximately $465 million.

Secure Computing is a leading provider of network security with a product portfolio that spans businesses of all sizes. Through the pending acquisition of Secure Computing, McAfee expects to take another step toward its goal of strengthening its leadership position in security risk management (SRM).

Secure Computing delivers a comprehensive set of solutions that help customers protect their critical Web, email and network assets. With the pending addition of Secure Computing’s products and services, McAfee expects to be able to deliver the industry’s most complete network security portfolio (covering intrusion prevention, firewall, Web security, email security and data protection, network access control), from small and mid to the world’s largest organizations.

“Today’s announcement of this pending acquisition is a natural extension of McAfee’s security-only focus,” said Dave DeWalt, chief executive officer and president of McAfee. “We expect the pending combination of McAfee and Secure Computing will create an annual projected combined revenue of just under $500 million in the network security segment of our SRM portfolio. We believe that this pending acquisition will allow us to immediately establish a leading and highly competitive position in the network security space.”

The rationale for the proposed acquisition is as follows:

  • With Secure Computing, McAfee expects to become one of the largest network security players, delivering the industry’s most complete network security solution to businesses of all sizes, extending the success of its total protection strategy through best of breed technology suites
  • Secure Computing TrustedSource technology will extend McAfee’s “in-the-cloud” security as a service offering
  • With Secure Computing, McAfee expects to be able to deliver the complete content and data lifecycle management at the network, spanning detection, filtering, encryption, blocking, archiving, reporting and compliance
  • Secure Computing has more than 22,000 customers in 106 countries that will be able to rely upon McAfee as a single source for complete security portfolio—spanning endpoint, network, data and risk and compliance

“I believe the combination of the two companies will allow us to reap the benefits of a worldwide dedicated sales team three times our size, best-in-class security research, greater partner distribution and enhanced cross-selling opportunities,” said Dan Ryan, president and chief executive officer, Secure Computing. “Combined, we believe we will become a leader in the network security space.”

The proposed acquisition is subject to regulatory approvals and Secure Computing stockholder approval, and is expected to close in the latter part of the fourth quarter of 2008. McAfee anticipates that following the closing, Secure Computing’s technologies will be incorporated under McAfee’s Network Security product business unit, headed by Dan Ryan.

For additional information, please reference http://www.mcafee.com.

Forward-Looking Statements:

This release contains forward-looking statements, which include those regarding McAfee’s future plans for the Secure Computing business, the expected closing date of the acquisition, the expected financial impact of the Secure Computing acquisition on McAfee’s earnings, and expectations as to the future revenue of the combined McAfee and Secure Computing network security segment. Factors that could cause McAfee’s actual results or outcomes, levels of activity, performance or achievements, including the realization of expected financial and other effects of the acquisition, to be materially different from those anticipated in this release include among others, the inability to integrate successfully Secure Computing within McAfee or to realize synergies from such integration; costs related to the acquisition of Secure Computing; inability to obtain necessary regulatory approval or to obtain them on acceptable terms; the economic environment of the industries in which McAfee and Secure Computing operate, as well as facts relating to Secure Computing that may impact the timing or amount of synergies they can be realized and that are unknown to McAfee. In addition, actual results are subject to other risks and uncertainties that relate more broadly to McAfee’s overall business, including those more fully described in McAfee’s filings with the SEC including its annual report on Form 10-K for the year ended December 31, 2007, and its quarterly report filed on Form 10-Q for the second quarter of 2008.

The Browser War is Back: Choosing the Best Web Browser for PRTG Network Monitor

0 comments

Posted on 11th September 2008 by admin in PRTG |Paessler

, , , , ,

Those of you who use Paessler’s PRTG might be interested in this article as it discusses (due to the introduction of Google’s new Chrome web browser) which web browser works the best with PRTG.

The original article can be found at:

http://www.paessler.com/blog/2008/09/05/prtg-7/the-browser-war-is-back-choosing-the-best-web-browser-for-prtg-network-monitor/?utm_medium=nl&utm_source=PN08-09-09

The Browser War is Back: Choosing the Best Web Browser for PRTG Network Monitor

Since Google have launched their new browser “Chrome” a few days ago development in the world of Web browsers is becoming quite interesting. The new contender Chrome has already created a lot of buzz and includes a number of innovative features that will raise the innovation pressure for the other players.

We wanted to know which one of the four most used browsers is the best for accessing PRTG Network Monitor’s web interface which offers an ajaxified web interface experience.

Just last week we had added experimental support for the WebKit rendering engine (used by Safari and Chrome) to the latest beta of PRTG 7.0.9. So we could start right away testing Chrome against IE7, Safari 3.1 and Firefox 3.

The results in short:

  • Don’t use IE7 with PRTG Network Monitor (or other websites with heavy Ajax/Javacript usage), it is simply the slowest browser by far
  • You can’t go wrong using Firefox 3, it has the best overall experience
  • Safari seems to provide the fastest Javascript processing
  • No other browser manipulates DOM objects in the browser window as fast as Chrome

The plain numbers only tell about a speed difference of factor 4 between the fastest and the slowest browsers. From a subjective perspective (meaning: sitting in front of it and using PRTG’s interface) the difference feels more like factor 10 to 20 between Chrome and IE7.

Conclusion:

Because the support for WebKit (Safari/Chrome) is still experimental in PRTG the best choice right now is Firefox 3.

The future seems to look bright for web based application users as faster browsers are coming up. Chrome has raised the bar for the others. Mozilla has already announced a new and improved Javascript engine for the next version of Firefox. Safari 4 is also expected to include a new Javascript engine.

Note: We did not perform any speed tests with IE8 beta 2 yet, although support for IE8 has also been built into V7.0.9 of PRTG Network monitor as of last week. IE8 is expected to be on-par with Firefox 3, but the others are already going the next step…

Details:

Here are the detailed results of our runtime tests with various Javascript functions of the PRTG Network Monitor 7 web interface:

Test 1: Installing various DOM events on the “group.htm” page:

  • Safari 3.1: 130 ms
  • Chrome: 170ms
  • Firefox 3 (with Firebug): 550ms
  • Firefox 3 (without Firebug): 170ms
  • IE7: 500ms

Test 2: “Tab switching” on the “group.htm” page (tabbing from from the sensor tree view to the “edit root group” page):

  •  Safari 3.1: 90 ms
  • Chrome: 70ms
  • Firefox 3 (without Firebug): 110ms
  • IE7: 430ms

Tests were performed on a DELL Precision 390 (Intel Core 2 CPU X6800, 2.93 GHz, 4 GB RAM), all four browsers and the PRTG Core Server ran on the same system.

Barracuda Spam Firewall Rejects Invalid Non-Delivery Report Messages

0 comments

Posted on 10th September 2008 by admin in Barracuda Networks |Spam Firewall

, , , , , ,

Barracuda Networks Inc., the worldwide leader in email and Web security appliances, recently announced a new feature in the Barracuda Spam Firewall that can differentiate legitimate Non-Delivery Report (NDR) messages – also known as bounce messages – from invalid NDR messages resulting from spoofing attacks. Using [tag]Invalid Bounce Suppression[/tag], the [tag]Barracuda Spam Firewall[/tag] prevents “backscatter” messages from reaching innocent email senders.

“Backscatter is an unfortunate side effect of the continued prevalence of email spoofing by spam campaigns that is now plaguing corporate email servers,” said Stephen Pao, vice president of product management for Barracuda Networks.  “It is also a frustrating, and sometimes confusing, problem for email users who are the innocent victims.”

Backscatter occurs when spammers, hackers or other users with malicious intent, spoof the email addresses of legitimate email users to send spam, viruses or worms.  The receiving email server typically rejects the email and sends an NDR message to the spoofed email address. As a result, the legitimate email user receives a bounce message for emails that they never sent.

“While one common technique to minimize the impact of backscatter is to simply define policies to block all incoming bounce messages, doing so can result in the blocking of legitimate bounce messages,” said Pao.  “As such, distinguishing legitimate from invalid bounce messages can be extremely important to users who send business-critical email.”

Invalid Bounce Suppression tags the sender addresses of all outgoing messages sent from the Barracuda Spam Firewall’s outbound relay, or through the Barracuda Spam Firewall-Outbound appliance.  The tags are encoded with built-in expiration periods and encrypted to prevent forgery.  When an NDR message is received by the Barracuda Spam Firewall, a valid tag must be present in the bounce recipient address (i.e., the original sender address) for the bounce message to be delivered.  If the bounce recipient address does not contain a tag or if a tag is invalid, the NDR message is rejected.  Usage of the Invalid Bounce Suppression feature is transparent to legitimate senders and recipients.

“Beyond the reputation benefits of preventing spam and viruses from leaving an organization’s network, Invalid Bounce Suppression has a direct impact on reducing the amount of unwanted email that hits users’ email inboxes,” added Pao.  “Invalid Bounce Suppression provides another compelling reason why organizations should also consider relaying their outbound email through an email security solution, such as the Barracuda Spam Firewall or Barracuda Spam Firewall-Outbound.”

In addition to Invalid Bounce Suppression, the latest Barracuda Spam Firewall version also includes additional rules governing email policy, including new policy rules for character sets used in emails and attachments, reverse DNS resolutions of sending email servers, and full URLs (including query strings) embedded in emails.

Pricing and Availability:

The latest features, including Invalid Bounce Suppression, are available with Barracuda Spam Firewall firmware release 3.5.12 and above.  The Barracuda Spam Firewall is available in eight models with prices starting at $899.  International pricing and availability varies based on region.

About the Barracuda Spam Firewall:

The Barracuda Spam Firewall is available in eight models and supports up to 100,000 active users with no per user licensing fees.  Its architecture leverages 12 defense layers: denial of service and security protection, rate control, IP analysis, sender authentication, recipient verification, virus protection, policy (user-specified rules), Fingerprint Analysis, Intent Analysis, Image Analysis, Bayesian Analysis, and a Spam Rules Scoring engine.  In addition, the entire Barracuda Spam Firewall line features simultaneous inbound and outbound email filtering with the inclusion of sophisticated outbound email filtering techniques, such as rate controls, domain restrictions, user authentication (SASL), keyword and attachment blocking, triple-layer virus blocking, and remote user support for outbound email filtering.  The Barracuda Spam Firewall’s layered approach minimizes the processing of each email, which yields the performance required to process millions of messages per day.

Launch of GFI MailArchiver 6 – Stub-free email archiving is industry-first

1 comment

Posted on 3rd September 2008 by admin in GFI

, , , , , , , ,

The latest version of GFI MailArchiver will be released on September 2. The main feature in version 6 is integration with Microsoft’s Outlook email client. GFI is the first email archiving vendor to offer Outlook integration without the use of stub files. The use of stub files is not recommended by Microsoft due to their impact on Exchange (for more information visit Microsoft has a negative stance against stubbing and the Microsoft white paper).

Outlook integration will enable users to search and access all their old and deleted emails from a folder in their Outlook email client as if it were their Exchange mailbox or local PST file. Outlook integration reduces the workload for administrators and offers a much faster and improved archiving experience than products using stubs to access archived emails.
