Cisco Is Launching A New Type Of Network To Help Stop Cyberattacks

  • Cisco's new "intentional-based" networking solution can detect malware even when it is hidden in encrypted traffic.
  • Cisco says it is using automatic learning and artificial intelligence to help detect these threats.

Cisco announced the launch of a completely new network based on intentions that will be able to detect malware when hidden in encrypted traffic, something that states no other company can do.

The new technology could make it more difficult for cyber-attackers to carry out attacks against organizations using Cisco equipment.

"We are ushering in a new age of networks that is driven by intent, informed by context and over time continues to adapt and learn," Cisco president Chuck Robbins told CNBC's David Faber. "This is a seminal moment in networking."

Cisco says that this new intentions-based software, Encrypted Traffic Encryption, is the most advanced way to detect anomalies in billions of devices and data. ETA is able to detect pattern abnormalities in encrypted traffic without compromising privacy, Cisco says.

The software, which will be offered as a subscription service, is currently in field trials with 75 clients, and according to Robbins, it is 99 percent effective.

"With our investors we've been talking about this ongoing shift toward greater software content in our business," Robbins said. "We believe this launch today is the start of a journey to help us launch that software and subscription model in our core, which is what our investors have been asking us."

Shares of Cisco were under pressure last month when the company gave fourth-quarter revenue guidance that was below expectations. So far this year, shares have risen about 7 percent.

Cisco Systems: Good Income And Total Return For This Computer Network Provider

Summary
  • Cisco Systems' total return exceeded the DOW average for my 53-month trial period by 18.96%.
  • Cisco Systems has increased its dividend for 7 of the last 10 years with a current yield of 3.6%, which is well above average.
  • The price of Cisco Systems can gain some traction if the president of the United States reduces the tax on foreign earnings.




This article is about Cisco Systems (CSCO) and why it is a purchase for the total return investor with interest also for the dividend growth investor. Cisco Systems develops a range of information technology products that provide integrated solutions to the computer network infrastructure in the United States and in foreign countries. I've had comments on previous articles about why I compare performance with DOW average, so I'll look at some other DOW companies and see how they work well enough to add to my portfolio. The third to consider is Cisco Systems and is a buy when forward growth improves. I use the DOW because six of the good business portfolio companies are in the DOW and got there because they are good businesses that make money in good times and bad.The basics of Cisco Systems will be reviewed on the following topics: The Good Business Portfolio Guidelines, Total Yield and Annual Dividend, Last Quarter Earnings, Company Business and Recent Portfolio Changes and Changes.


I use a set of guidelines that I coded in recent years to review the Good Business portfolio (my portfolio) and other companies I'm checking out. For a complete set of guidelines, see my article "The Good Business Portfolio: Guidelines Update and Performance Review for July 2016." These guidelines provide me with a balanced portfolio of revenue, defensive, total return and business growth that I hope keeps me ahead of the Dow average.
