| SCENARIO 2 |
| Characteristic | Exposure | Description |
| Security Risk | HIGH | All viruses reach the corporate email server |
| Maintenance | MEDIUM | Only email server needs to be constantly maintained (virus and spam software) |
| Cost | MEDIUM->HIGH | Each new email client needs to be licensed (virus and spam software on the email server - ie Symantec, McAfee, SurfControl, etc. all based their licensing on the number of email boxes) |
| Scalability | LOW | Very limited vertical scalability as it directly depends on the email server hardware. Also as an added nuisance, the performance of the email server directly depends on the amount of overhead that it has to do in order to process viruses and spam load. |
| Economies of scale | LOW | The more you grow the more it costs - each new employee workstation increases the overall solution cost. |
