Cloud Web Security (CWS) and Data Center Standards
Takes standards and procedures very seriously as a Security-as-a-Service provider

Cloud Web Security (CWS) and Data Privacy

Cisco® Cloud Web Security (CWS) takes standards and procedures very seriously as a Security-as-a-Service provider. In the data center and networking industries, al though certain Service Provider and Accreditation standards do exist, there is no central governing body regulating data center standards and procedures for cloud services. In many ways, providers define their own best practices. Cisco CWS data centers provide best in class cloud delivered security, with best in class infrastructure security and integrity, strict standards, true multi-tenant service, high resiliency and scalability.

Service Provider Accreditation and Best Practice

As mentioned, a lthough there is no central governing body, all of Cisco CWS partners are accredited or follow best practices as defined by various bodies in relation to their standards and procedures. These include, but are not limited to:

Cisco CWS European Datacenter providers are ISO27001:2005 Security Management certified (Germany IDW PS 951 certified), which ensures the proper selection of adequate and proportionate security controls to protect all information assets in Datacenters.

Service-Providing Infrastructure Standards and Procedures

Cisco CWS maintains the following standards and undertakes the following procedures in relation to the infrastructure that provides its services:

Infrastructure and Redundant Power

Cisco CWS Datacenters providers have a global average uptime of >99.999%. That means each of the Cisco CWS Datacenters typically experiences outages totalling less than 5 minutes and 15 seconds over the course of a year.

To ensure power is always available, Cisco CWS Datacenter providers have a minimum of N+1 power redundancy, meaning every mission-critical component has at least one backup power feed fed by UPS and with generator backup. Each Datacenter location also stores fuel on site to provide emergency power in the event of an ongoing power outage, and contractual agreements exist with fuel suppliers to ensure long term continuous operation.

Network Security

The network is protected by a number of layers:

In addition, CWS proxies will reject any web requests that do not include a valid license key from a current customer, or originate from non-recognized sources.

Physical Security

Access to the buildings, data floors and individual areas is monitored by 24/7 security. Personnel access each of the Cisco CWS Datacenter facilities by using a combination of biometrics and passcode security required at both building entry and the DC floor. Standardized procedures also ensure that only nominated staff gains access to our equipment whenever required, day or night.

Entry to each facility is tightly controlled, with strict procedures in place to monitor and control visitor access both into and within the Datacenter. Extensive CCTV video camera surveillance is in place across each facility, along with security breach alarms, biometric checks and controlled physical barriers.

Minimum Datacenter Facility Standards

For a datacenter facility to be considered as a location to host Cisco CWS equipment, the following is required:

Minimum Network Service Standards

For a network service to be considered suitable for access to Cisco CWS, the following is required:

Energy efficient

Cisco CWS takes cooling very seriously in its Datacenters and uses a combination of water-based, fully-redundant air conditioning. In addition hot aisles/cold aisle designs and innovate containment solutions are used for the best cooling. Energy efficiency has been at the forefront of the design and build of Cisco CWS Datacenters. Many Cisco CWS Datacenters benefit from free cooling systems which enable significant savings when the external ambient temperatures fall below a certain level.
