A
Resilient
Network
Architecture
for
Your
Distributed
Enterprise
Dear
Mr
.
Chen
,
I
am
reaching
out
because
your
organization
is
navigating
one
of
the
most
complex
networking
transitions
in
years
.
Over
the
past
thirty
-
six
months
,
your
workforce
has
shifted
to
hybrid
and
remote
models
,
your
branch
offices
now
rely
on
direct
internet
access
to
cloud
applications
,
and
your
operational
-
technology
footprint
has
expanded
well
beyond
the
traditional
campus
perimeter
.
Yet
much
of
your
infrastructure
still
rests
on
legacy
switching
,
siloed
wireless
controllers
,
and
perimeter
-
based
security
models
that
were
architected
for
a
time
when
every
user
and
application
sat
inside
one
building
.
The
result
is
a
fragmented
network
that
your
IT
team
manages
through
multiple
disconnected
dashboards
,
command
-
line
interfaces
,
and
vendor
-
specific
tools
—
creating
blind
spots
between
the
LAN
,
the
WAN
,
and
the
cloud
edge
.
Cisco
has
spent
four
decades
architecting
the
enterprise
networks
that
power
the
world
'
s
most
demanding
organizations
.
Our
intent
-
based
networking
portfolio
—
spanning
Cisco
Catalyst
switching
and
wireless
,
Cisco
Catalyst
SD
-
WAN
,
Cisco
Meraki
cloud
management
,
and
Cisco
Secure
Access
—
unifies
your
campus
,
branch
,
and
remote
connectivity
under
a
single
,
resilient
architecture
.
Unlike
environments
that
force
you
to
bolt
together
switching
,
wireless
,
WAN
,
and
security
from
separate
vendors
,
Cisco
offers
an
integrated
platform
engineered
to
enforce
consistent
policy
,
visibility
,
and
security
from
the
data
center
to
the
remote
worker
.
It
is
the
same
infrastructure
that
supports
global
financial
institutions
,
healthcare
systems
,
and
industrial
leaders
—
built
for
organizations
that
treat
connectivity
as
mission
-
critical
.
Here
is
how
it
addresses
the
specific
constraints
you
face
today
.
1 / 4
First
,
Cisco
Catalyst
Center
and
Cisco
Meraki
replace
manual
,
box
-
by
-
box
network
management
with
centralized
automation
and
cloud
-
native
control
.
Your
network
administrators
gain
a
unified
view
of
every
switch
,
access
point
,
and
WAN
edge
on
the
network
,
with
AI
-
driven
analytics
that
proactively
identify
anomalies
,
recommend
optimizations
,
and
accelerate
troubleshooting
before
users
open
tickets
.
For
an
organization
managing
dozens
of
sites
alongside
a
growing
remote
workforce
,
this
capability
compresses
operational
overhead
and
eliminates
the
configuration
drift
that
typically
leads
to
security
gaps
and
downtime
.
Second
,
Cisco
Secure
Access
and
Cisco
Duo
deliver
zero
-
trust
network
access
that
replaces
legacy
VPN
bottlenecks
with
a
cloud
-
native
security
edge
.
Every
connection
—
whether
from
a
headquarters
desk
,
a
home
office
,
or
a
temporary
field
site
—
is
verified
continuously
based
on
user
identity
,
device
posture
,
and
real
-
time
threat
intelligence
from
Cisco
Talos
.
Your
security
team
gains
consistent
enforcement
across
all
entry
points
without
backhauling
traffic
through
centralized
data
centers
,
which
means
hybrid
workers
experience
direct
,
low
-
latency
access
to
SaaS
applications
while
your
organization
maintains
enterprise
-
grade
protection
.
Third
,
Cisco
ThousandEyes
and
Catalyst
wireless
technologies
provide
end
-
to
-
end
visibility
into
the
experience
your
users
actually
receive
.
ThousandEyes
monitors
path
performance
across
the
internet
,
into
SaaS
providers
,
and
through
your
SD
-
WAN
fabric
—
pinpointing
whether
an
outage
stems
from
your
LAN
,
an
ISP
,
or
the
cloud
provider
itself
.
When
combined
with
Wi
-
Fi
6
E
and
Wi
-
Fi
7
ready
Catalyst
wireless
,
this
intelligence
ensures
that
video
collaboration
,
real
-
time
IoT
telemetry
,
and
cloud
-
based
design
tools
perform
reliably
,
even
in
high
-
density
environments
.
The
business
value
extends
far
beyond
IT
simplification
.
Organizations
that
standardize
on
Cisco
'
s
integrated
networking
platform
typically
reduce
operational
complexity
by
converging
network
and
security
management
onto
common
cloud
and
on
-
premises
dashboards
.
Your
IT
team
gains
hours
back
every
week
through
automated
provisioning
and
policy
updates
.
Your
security
team
gains
a
hardened
architecture
with
embedded
encryption
and
segmentation
that
isolates
critical
devices
without
re
-
engineering
the
network
.
Your
application
owners
gain
SLA
-
grade
visibility
into
how
cloud
services
perform
from
every
branch
and
every
home
office
.
Most
importantly
,
your
executives
gain
confidence
that
the
network
is
no
longer
a
constraint
on
geographic
expansion
,
M
&
A
integration
,
or
new
digital
service
launches
.
2 / 4
Cisco
is
consistently
recognized
as
a
Leader
in
the
Gartner
Magic
Quadrant
for
Enterprise
Wired
and
Wireless
LAN
Infrastructure
and
serves
as
the
established
market
leader
in
enterprise
networking
,
powering
the
campus
and
branch
environments
of
the
majority
of
the
Fortune
Global
500
and
the
world
'
s
largest
public
-
sector
networks
.
Our
security
research
organization
,
Cisco
Talos
,
is
one
of
the
largest
commercial
threat
-
intelligence
teams
in
the
world
,
analyzing
billions
of
DNS
requests
,
malware
samples
,
and
network
flows
daily
to
inform
protections
that
deploy
automatically
across
Cisco
security
and
networking
products
.
Cisco
ThousandEyes
monitors
billions
of
internet
and
cloud
measurements
every
day
,
providing
the
external
visibility
that
traditional
network
monitoring
cannot
reach
.
When
you
choose
Cisco
,
you
are
not
purchasing
another
point
product
;
you
are
adopting
the
networking
platform
that
has
defined
enterprise
connectivity
standards
for
nearly
four
decades
.
Delay
has
a
cost
.
Every
month
your
teams
spend
navigating
disjointed
management
tools
,
troubleshooting
wireless
coverage
gaps
manually
,
or
responding
to
security
incidents
without
unified
visibility
is
a
month
where
competitors
with
modernized
networks
are
onboarding
new
sites
faster
,
enabling
seamless
hybrid
work
,
and
delivering
cloud
-
based
services
without
friction
.
The
question
is
not
whether
your
organization
can
afford
to
modernize
its
network
;
it
is
whether
you
can
afford
to
let
operational
complexity
and
blind
spots
compound
as
your
distributed
footprint
grows
.
I
would
like
to
invite
you
to
a
private
45-
minute
Executive
Network
Architecture
Briefing
tailored
to
your
current
environment
and
hybrid
-
work
roadmap
.
We
will
walk
through
how
Cisco
Catalyst
and
Meraki
simplify
your
multi
-
site
operations
,
how
Secure
Access
replaces
legacy
VPN
constraints
with
zero
-
trust
connectivity
,
and
how
ThousandEyes
extends
visibility
into
the
cloud
applications
your
business
depends
on
.
There
is
no
obligation
—
only
a
substantive
conversation
about
what
is
possible
when
your
LAN
,
WAN
,
and
security
edge
are
engineered
to
function
as
one
platform
.
Please
reply
to
this
letter
or
contact
me
directly
at
the
number
below
to
reserve
a
time
that
works
for
your
calendar
.
I
am
available
the
week
of
June
23
rd
and
will
gladly
accommodate
your
schedule
.
Sincerely
,
