Thanks Masnrock for the review.<br />

&gt;Yes, if it recognizes a domain that's been looked up in DNS as a malicious domain. This is by no means a replacement for a web filter.<br />
So a webfilter with 'Bad Reputation sites' feature will be better? &nbsp;Or a proxy (say Bluecoat) with 'Bad Reputation Sites' feature is better?<br />
<br />
<br />
Will wait for any other experts giving comparison between the above listed products

I need to compare/evaluate various DNS security products, meant to to prevent <br />
users accessing malicious sites; &nbsp;not sure if it'll help with spam (say user register<br />
their emails in unsolicited sites &amp;&nbsp;got spammed from hereon).<br />
<br />
A few products below come to mind but I don't know how to go about <br />
comparing/assessing:<br />
Cisco Umbrella<br />
Dyn<br />
FoolDNS<br />
Greenteam Internet<br />
Infoblox<br />

Much appreciated some guidelines &amp;&nbsp;inputs

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
