As threats to information and network systems continue to increase, companies and organizations with large networks are implementing different layers of security. There are firewalls, anti-virus, spam and content filtering, vulnerability scanning, and anti-penetration hardware. However, these security layers can be integrated by using UTM appliance. UTM stands for unified threat management and is considered as the most efficient way of managing security threats and vulnerabilities. With a single threat management appliance, network administrators will have an easier time detecting vulnerabilities and creating countermeasures to prevent external and internal attacks.

A UTM appliance is a piece of hardware that can be deployed on a large network. Such hardware has multiple security capabilities and features so it serves as an all in one security solution for corporate networks. Once deployed, a UTM device can perform regular vulnerability scanning of the entire network. Typically, you will need a penetration testing appliance or vulnerability scanning software to detect areas in your network that could become a potential source of problems. A UTM appliance can perform such task thus rationalizing the security solution of a network.

Another common security layer that is being deployed by companies is a spam and web content filtering system. Some of the most virulent viruses, Trojans, and worms penetrate a network through spam email messages. Normally, these viruses are contained in PDF attachments, media files, and streaming audios or videos. Malicious scripts and backdoor Trojans, on the other hand, may come from unsecured files downloaded through P2P sharing sites. Spam filtering systems can block such unsecured content from penetrating the network of a company. With a UTM appliance, there is no need anymore to deploy additional anti spam protection because this can be accomplished by the UTM device.

A UTM appliance can also be used as a control gateway of the network. Network administrators can configure such device to control the traffic coming in and going out of the network. It can also serve as a site filtering device to control the browsing activities of each workstation within the network. With its built-in vulnerability scanning capability, deploying a UTM system can significantly help IT managers and administrators in keeping the network safe from attacks. It can prevent access to desktop applications that can be used for personal purposes. It can also prevent heavy downloads of streaming media which affects the performance of corporate networks.

Your company can save resources by implementing a unified threat management system. If you have different security layers coming from different providers, you will have to pay for the regular upgrades of your network’s security devices and software. But with a UTM system, the cost of upgrading it would be cheaper and affordable. You will also deal with one provider only thus technical glitches can be solved faster. Most importantly, a UTM device can be deployed without disrupting the operations of the network. You can implement it over your network without rebooting your servers. So your company will stay live and productive during deployment and configuration of the UTM system.
