This report uses the NSS Labs Total Cost of Ownership (TCO) model to calculate TCO for advanced endpoint protection (AEP) products. The model assumes that enterprises that do not deploy AEP security, or that deploy an AEP security product with low protection, will incur less security savings in the event of a breach, since additional operational overhead will be required to remediate the effects of a compromised system and protect the business. Furthermore, security products that do not provide visibility and forensic detail will realize less security savings because compromises will have to be investigated manually, which would increase operational cost.
