DATA BREACHES
are making headlines
There were more data breaches
in 2014 than any year on record
The average cost of a data breach is now
$3.8 MILLION
AND SNOWDEN REVEALED GOVERNMENTS
HAVE SWEEPING SURVEILLANCE POWERS
Among them, the NSA:
Taps fiber optic cables that
carry much of the world’s
Internet traffic
Collects over 200
million text messages
each day
Intercepts unencrypted
data sent between Google
and Yahoo data centers

Security experts agree

Edward Snowden
“Encryption works. Properly
implemented strong crypto
systems are one of the few
things that you can rely on.”
Millions of people
encrypt data on their computers,
but what about when they use apps?
EMAIL IS LIKE A POSTCARD
Anyone who handles
your email in transit can
read it, including your
ISP, a hacker, or the NSA
Here are some secure alternatives
Encrypted so provider
can’t read it?
Encrypted in transit?
CryptoCat Silent Text Silent Phone Signal/RedPhone ChatSecure + Orbot
Can you verify
contacts’ identities?
Are past communications
secure if keys stolen?
Is code open to
independent review?
Is security design
properly documented?
Has code been audited?
Here are some secure alternatives

And when you browse the Internet,
people can see the unencrypted
data sent to and from a website
JUST 1.9%
of the Internet’s top 1
million sites use HTTPS
encryption by default
Browser plugins like HTTPS Everywhere
can switch to encryption to thwart
surveillance and cyber criminals

When it comes to the cloud,
of apps encrypt

Some of the biggest names in cloud computing
don’t store customer data encrypted
1. Facebook
2. Twitter
3. YouTube
5. Linkedin
6. Gmail
7. eBay
8. Paypal
4. TubeMogul
10. AOL Mail
9. Hotmail

APPSthat don’t encrypt data
WHY DOES IT MATTER?
When the government seized Megaupload’s servers, they
seized all the data customers had uploaded to the service
When hackers gained access to
Slack’s core systems, they stole
unencrypted usernames, email
addresses, phone numbers, and
Skype IDs
When data is stored encrypted, it is
by any third parties who may gain access
not readable
There are many encryption options
available today
