3. Broad Objective of Web Access today
Provide liberal Web 2.0 Internet Access to
Users with a good user experience while,
Ensuring security from malware, virus and
similar Web threats and,
Ensuring the security of Business
confidential information against leakage
- All of the above at
Costs that are predictable and optimal
4. Secure Web Access - Components
• Protection from
The Dynamic Malware,
Outside - In
Threats Viruses etc.
• Protection from
The Inside- Loss of Confidential
Out Information to the
Threats Internet
• Deliver a fast
browsing
Great User experience to the
Experience users
• At predictable costs
to the business
5. Liberal Internet Access Policy and No caching
Result:
• Dissatisfied Users
• Higher Annual
Bandwidth Costs
Poor response times
No caching=> Higher
Demand for bandwidth
Higher Internet usage
from user community

6. Liberal Internet Access Policy and Good caching
Result:
• Satisfied Users
• Controlled and Stable
Annual Bandwidth Costs
Faster response times
30 % Caching – Same
or Reduced bandwidth
Higher Internet usage
from user community

7. Bandwidth Cost Paradox
Unit Cost per
Mbps of
Bandwidth is
coming down
Total
Budgetary
Outlay for
Bandwidth has
gone up
What matters to the business is the Overall money spent on Bandwidth –
year after year.
8. Cost Savings with a Good Caching & Bandwidth
Management
Savings in 5
Years
Average through
Annual caching:
Average expenditure 112L
Cache Ratio: on Bandwidth
30% 75 L
9. Caching delivers great User Experience
• Performance for 2nd request
5X onwards for a web object
• Benefits all users
• Performance for 1st request
for web object
2X • Benefits the first user
requesting the web resource
10. Video Content consumption is on the Increase
Estimated proportion of
90% Video Content
consumption: 2012-
2014
Current estimate of the
proportion of Video out 25 -
of total Internet content
Consumption 30%
11. Video Content is…
Bandwidth Video consumes
Heavy higher bandwidth
Usability of the
Latency
video is sensitive to
Sensitive
latency – Jittery
to Users
video is unusable
12. Look for Cache that can do Media Stream Splitting &
Caching
Great User • Faster Videos
experience • No jitter
Less • User sensitivity to poor Video
complaints rendering is high
from Users
Control on IT • While delivering good user experience
• At great bandwidth gains and lower
Budgets bandwidth costs
13. Closing Thoughts
Web 2.0 makes the Internet a rich interactive application platform with two way
content a reality, increasing the chance of malware infection
HTTP/S replaces SMTP as the new primary threat vector. Email now delivers
pointers to MMC/malware infected websites
Email/web reputations scores are for the obvious. Professionals use reputable/trusted
sites to deliver malware
Selective Scanning migrates to a “Scan Everything” policy, a site is only as good as
its last transaction
Blocking impedes business value of Web 2.0 applications. SWGs need threat
protection layers and acceleration
Good caching not only provides hard savings through Bandwidth gains but also helps
in giving a fast and great Internet experience to users
Video content consumption is on the increase and media stream splitting and caching
provides good user experience while reining in potential bandwidth increase costs
