If you deploy custom tags in a multideveloper environment or distribute your tags publicly, you can use the advanced security and template encoding capabilities of ColdFusion.

The ColdFusion security framework enables you to selectively restrict access to individual tags or to tag directories. This can be an important safeguard in team development. For more information, see Securing Applications.

You can use the command-line utility cfcompile to precompile your custom tag files into Java class files or byte code. For more information, see "Using the cfcompile utility" in Configuring and Administering ColdFusion..
