Cisco CWS and OpenDNS Data Center Locations

Cisco Cloud Web Security (CWS) and OpenDNS both provide cloud based security services. CWS offers an HTTP/HTTPS proxy and OpenDNS provides security and visibility at the DNS resolution layer. I’ve been asked many times where both CWS and OpenDNS host their services as this can make a big impact in end user experience if the hosting location is far away from the user and could lead to high latency and a lousy experience.

Cisco Tools Link

I regularly share useful links with customers and colleagues and often find that this page is a great starting point to explore some of the web tools Cisco has available http://www.cisco.com/c/en/us/support/web/tools-catalog.html

Some of these tools include the Cisco Power Calculator, Cisco Feature Navigator, Cisco IOS to NX-OS configuration converter, and many others. Give it a click and explore some tools you likely didn’t even know existed.

Cisco Cloud Web Security

Link

Cisco acquired a company named ScanSafe in 2009 to provide cloud based web proxy services and this service was renamed to Cisco Cloud Web Security (CWS). Cloud Web Security offers an alternative to on premise proxy services by hosting proxy services in data centers around the world. There is a single management portal where an administrator can create policies and run reports. Once a policy is created it is available across all the proxy servers around the world which greatly decreases the burden of creating consistent policies.

There are a variety of ways to leverage CWS including:

  • Cisco AnyConnect
  • Connectors for Cisco ISR G2 routers (1900, 2900, and 3900 series)
  • Connectors for Cisco ISR 4000 routers (4300, 4400 series)
  • Connector for Cisco ASA firewalls
  • Integration with the on premise Web Security Appliance (WSA)
  • Direct integration via client proxy configuration (point your operating system to the CWS proxy)

The connectors for the routers and firewalls offer transparent redirection which makes deployment very straightforward. The integration with AnyConnect provides a very simply solution for securing internet access for users when they are outside of the corporate network without requiring all internet traffic to be backhauled.

More information on the service can be found here http://www.cisco.com/c/en/us/products/security/cloud-web-security/index.html and information on the current proxy locations is available here http://servicestatus.sco.cisco.com/status

Check Cisco Warranty and SMARTnet Coverage

Need a simple, easy way to check if a piece of Cisco hardware is covered under warranty or SMARTnet? Look no further than this useful site: https://cway.cisco.com/sncheck

You will need to login using your Cisco.com (CCO) username and password, but then  you can check on coverage for ANY serial number. If the serial number is covered under a contract associated with your CCO account then you will see additional details including coverage end date and coverage level.

Web Based Network Diagramming Tool – Gliffy

I recently discovered the excellent web based diagramming tool named Gliffy. You can think of it as a web based version of Microsoft Visio at a high level. In addition to network diagrams you can create flowcharts, org charts, sitemaps, user interface diagrams, etc. The import/export functionality works well and even supports importing Visio VDX files (not VSD though). Gliffy offers smooth integration with Google Drive.

A free account offers you the ability to test drive the capabilities of their platform with a few limitations including:

  • Total diagrams are limited to 5
  • Storage is limited to 2 MB
  • Inability to create private diagrams (everything you create is viewable by anyone)

I encourage you to take their tool for a test drive at http://www.gliffy.com/
