Information Security News:
Cisco offers more email security choices, but lacks vision
03 Mar 2009 | SearchSecurity.com
Cisco Systems Inc is claiming to break new ground in email security by offering hosted IronPort-based service offerings. But there does not appear to be any new security capability introduced in the announcement.
Cisco allows enterprise customers the choice of IronPort antispam services in the cloud as either a managed or co-managed service, along with the added capability of outbound data leakage prevention and encryption that can optionally be deployed as customer premise equipment. The Security-as-a-Service offerings are targeted at enterprise markets.
It is disappointing that there is no new, additional security protection provided to customers today. Cisco's email security now looks more like that of Symantec with its Vontu and Brightmail security lines, or even email security services with Google-Postini or Webroot.
The Cisco announcement is a reminder of the three main questions IT should answer when evaluating new security-as-a-service models:
- Are there any savings based on shared equipment? One theme of SaaS approaches is that infrastructure costs are shared among subscribers, and that sharing more efficiently utilizes resources leading to direct operational costs savings. Cisco's email security service is a dedicated solution for each customer. Operational expenses such as hardware, rack space real estate, power and cooling are simply transferred from the customer data center to Cisco's data center. The consumptive elements of email security have not been reduced and it is hard to see significant cost savings in equipment utilization.
- Are there any savings in labor? Similarly, customers expect SaaS offerings to pass on operational cost savings achieved either from shared labor for routine tasks or from highly skilled labor for difficult tasks. The work of managing email security does not go away, and customers will have to pay Cisco a profit margin on top of labor expenses that the company would pay for anyway. Customers investigating Cisco's email security services should compare ongoing labor costs to ensure they are saving money.
- Are there any functional improvements in security coverage? Security in the cloud can leverage intelligence of Internet traffic to deliver security that cannot be reasonably achieved in the customer network. Cisco IronPort's reputation services are a perfect example of a security approach that can only be reasonably implemented in the cloud. Customers may already have DLP features in their Check Point firewalls or Code Green DLP devices, and email security in McAfee Inc.'s email appliances or Mi5 gateways. Ask Security-as-a-Service vendors how their approach delivers stronger security or coverage that the organization can't with traditional products.
Cisco's email security announcement will give customers more choices about securing their messaging infrastructure. It would have been nice to see more vision in Cisco's first offering. The ability to orchestrate security responsibilities between the cloud and customer premise equipment is intriguing, as is the ability to integrate full Web protection with email security as a service, for example. Cisco has an impressive security business and this announcement must be a springboard for future innovations. Let's hope so, as the customers will be waiting.
