Utm Appliances: Why Businesses Need One?

Unified Threat Management (UTM) is a comprehensive solution which embeds all the security applications in one device

. It has emerged as a primary network gateway defense solution to protect the data intensive environment of organizations. An UTM may comprises security functions such as network firewall, intrusion prevention, gateway anti-virus, gateway anti-spam, VPN, content filtering, load balancing and on-appliance reporting in a single appliance.

An UTM can be termed as the evolution of traditional firewall. It tackles the increasing number of attacks prevalent today in the form of hacking, cracking, malwares, viruses and worms.

Only recently, Enterprises have begun to realize that user ignorance can lead to security lapses and loopholes. Unauthorized employee access and data security are two of the biggest challenges faced by enterprises. It is also observed that newer hacking techniques target the users who eventually become the primary cause of internal attacks. Hence, most of the UTM products have 8th layer technology wherein user is treated as the eighth layer of the network stack and protected. The 8th layer or human layer of UTM allows organizations to create user identity based security policies beyond the 7 layers of network framework of Open System Interconnection or OSI.

An UTM eliminates the dependency on IP addresses and offer complete visibility into activities of users without compromising the performance of Internet connectivity. The elimination of IP address allows company management to carry its own access rights and policies anywhere in the network even in the dynamic IP environments like DHCP and Wi-Fi.

Moreover, organizations can simply do away with the management and expenses of several overbearing security applications. Companies also do not have to install multiple security applications to manage their Network Security. There is one device to worry about, one source of support and a single way to manage and ensure every aspect of data security.

In an UTM appliance, the security solutions are integrated and work in tandem to provide solution and promise high output. It is a bundle of solutions that delivers day to day report of running system and immediate feedback. From small, medium to large enterprises can utilize the comprehensive security provided by UTM appliances. It frees companies from the log and security management burden while ensuring industry compliance. It reduces TCO and risk management with swift response. Without degrading the quality of network performance, an UTM appliance gives companies the flexibility and ease of management through the unique Plug & Play Architecture and Web-based GUI while cutting down on the expenses of technical training requirements.
