Reasons I Hate Unified threat management (UTM)

A Unified threat management  UTM appliance is a hardware or it can be a software, device that is being install in to your network at the perimeter. It services includes gateway onto your corporate network, providing all the security services you need to protect your network from malware or any threat, unauthorized intrusion, and other security risks.

What I have researched i Think its a good approach but same time it include risk from which it made into my Hate list. Following Are some risk I can relate

Single point of failure: Also known as SPOF. A UTM contains all your security eggs in one basket, so if the UTM appliance fails, all your security systems fail. Many organizations get around this by having two UTMs, but this negates some of the cost and management benefits of a UTM.

Unnecessary costs: smaller organizations may require very few of the security features that a UTM offers, and may therefore pay for features that remain disabled.

Security efficacy: The risk mitigation provided by a UTM security appliance may not match the features and functionality of best-of-breed point solutions. In addition, UTMs may leave security holes if they simply offer a bundle of different products with a single interface rather than a genuinely unified solution.

Performance limitations: Enabling security features on UTM can have a hugely detrimental effect on the performance (in terms of data throughput) that an appliance offers.
