Who are the major players? We need a solid LAMP security company to keep our cloud instances secure, secure the PHP code (while maintaining functionality) and provide proactive/reactive resolution of OS problems and software (PHP/mySQL) problems when detected - particularly companies with the expertise to remedy these problems. .

We have a stage and production instance that will need these services and need a US-based company able to take care of us on an ongoing basis and willing to sign an NDA before gaining accessing the cloud (using SoftLayer).

Suggestions anyone? Thanks!
