Complete Security
Securing Mobile Devices
Fortinet designed and built FortiOS 5.2 to deliver the
advanced protection and performance that standalone
products simply can’t match. The services work together
as a system to provide better visibility and mitigation of the
latest network and application threats, stopping attacks
before damage can occur.
FortiOS 5.2 helps secure mobile device and BYOD
environments (including iOS®, Android® and Windows®
clients) by identifying devices and applying specific access
policies as well as security profiles, according to the
device type or device group, location, and usage.
Unique Visibility and Control
Advanced security features such as flow-based inspection
and integrated wireless controller capability allow you to
monitor and protect your wired and wireless networks
from endpoints to the core, and from remote offices to
headquarters. FortiOS allows greater traffic visibility and
more consistent, granular control over users, applications
and sensitive data.
Easier to Manage
FortiOS 5.2 lowers costs and reduces IT staff workloads.
Physical or virtual FortiGate appliances give you the
flexibility to match your security to your environment while
enforcing a uniform security policy. Single pane of glass
management and centralized analysis ensure consistent
policy creation and enforcement while minimizing
deployment and configuration challenges.
Client Reputation
Signature-based security alone is not enough anymore;
it is now critical to understand how devices on your
network are behaving. FortiView with threat score
provides a cumulative security ranking of each client
device on your network based on a range of behaviors. It
provides specific, actionable information that helps identify
compromised systems and potential zero-day attacks in
real time.
Smart Policies
FortiOS 5.2 enables intelligent, automatic adjustment
of role-based policies for users and guests based on
location, data, and application profile. Enhanced reporting
and analysis provides deeper insights into the behavior of
your network, users, devices, applications and threats.
Extensive Network Support
FortiOS supports numerous network design requirements
and interoperates with other networking devices. This
includes support for a wealth of routing, multicasting
and network resiliency protocols. Administrators can
also configure interfaces for VLANs, VLAN trunks, port
aggregation and one-armed sniffer mode.
It also offers robust high-availability and clustering options,
including advanced sub-second failover, virtual clusters and
much more.
Unified Access Security
FortiOS empowers organizations to apply consistent
policies across various types of networks, simplifying policy
enforcement in today’s complex environments. Its wireless
controller features extend the same protection to wireless
networks while endpoint control capabilities provision and
enforce security for mobile users even when they are away
from the office.
Device ID and User ID Access Control
FortiOS supports both local and remote authentication
services such as LDAP, Radius and TACACS+ to identify
users and apply access policies and security profiles
accordingly. It simplifies identity-based implementations
and also provides a seamless user authorization experience
with various single sign-on capabilities. FortiOS can
capture terminal service user or wireless login credentials,
among others, and intelligently apply policies and profiles
without additional user input.
As device types continue to evolve, you’ll be ready with
device access control. You can apply security policies
based on the type of device such as computers, tablets
or phones and apply different policies depending if the
devices are company or privately owned.
Sophisticated Application Control
Identifying applications and providing relevant enforcement
is essential in the current Web 2.0 and cloud environments.
FortiOS offers gradual controls and can identify over 3,000
applications, even those on encrypted channels. It also
offers mitigation against sophisticated botnet activities that
easily evade traditional firewalls.
Physical and Virtual Segmentation
From simple small wired networks to the complex multitenant managed datacenter environments, FortiOS
supports everything you need to set up and manage
your network traffic. You can configure physical network
segmentation using the LAN ports built-in to every
FortiGate, or you can provide virtual segmentation using
virtual LANs (VLANs).
Powerful & Scalable Management
FortiManager makes it easy to provision and manage
thousands of FortiGate devices in a distributed
organization. Using standardized setup profiles, you get the
ability to configure a standard set of policy and provisioning
workflows to meet your business needs or compliance
standards. Detailed configuration audit trails are supported
and can reside externally on secured storage with
FortiOS also integrates well with third-party solutions such
as Network Management Systems and SIEMs through
Fortinet’s technology alliances.
